Hydraulic Hose Replacement: To repair or replace?

When your hydraulic hose fails you, it will bring your hydraulic system to a standstill, can put your employees at risk, potentially damage your system, and can lead to a mess of environmental ramifications. The best way to prevent this from happening is to recognize the signs of impending failure, perform replacements before failure occurs, and take measures for foreseeable failures.

Hydraulic Hose Basics

The Hydraulic hose is used to transmit fluid through your hydraulic system, often at very high pressures and speeds. They are vital to the correct operation of your hydraulic system, whether it be a hydraulic power unit or an airport runway, or the hydraulics that power an excavator.

The Main Job of a Hydraulic Hose

Hydraulic hoses must contain fluids while they are being transferred while also protecting the fluid from outside containments. Hose failure means that 1. The hose is no longer able to contain the fluid and/or 2. It can no longer prevent outside containments from getting into the fluid. When a hose fails, it not only affects the system’s performance but can also lead to serious damage and expensive repairs to other components within the system.

Common Hose Issues

Your hydraulic hose should last you between a year or two years with many lasting up to ten years, so if you notice your hoses are failing in less than two years, then there are some external factors that are reducing its lifetime. Temperatures more than the recommended operating temperature, especially if the hose is making direct contact with a component that has extremely high temperatures, can cause a hose to fail. Contact with components that are involved in vibratory motion will lead to surface wear, abrasions, or cuts that can shorten the useful life of a hydraulic hose.

Chemical compatibility can also be another issue that compromises the integrity of the hose and can include the fluid used in the system or external chemicals that the hose comes in contact with. The material of the tube should always be selected to be compatible with the media that will be flowing through it. If there is incompatibility, the hose can weaken and eventually fail.

Also, using a hose that is not rated for the operating pressure of the hydraulic system can lead to damaging surge conditions whether the pressure is too high or too low. This incompatibility may be the result of the type of hose material of the type of reinforcement used in the hose. In addition, hydraulic fluid contamination can lead to wear within the hose as well as premature hose failure.

Lastly, your hose assemblies must be put together correctly, and the type of fitting must be compatible with the port it will be used with. The fittings themselves must be installed correctly as well or there can be a risk of a leak or other issues.

Hose Checks

It’s important to check your hoses for heat exposure, sun exposure and signs of again to prevent it from hardening and cracking. You should also look for kinks or excessive twists in the line, which will limit flow and lead to pressure buildup. Flat areas in your line indicate bad routing and could mean that the hose is pulling a vacuum or been pinched.

Check to make sure your hose is not rubbing on anything sharp and that no parts of it are worn or deeply cut. You should also inspect for leaks, especially at connection points, which are the most common points of failure.

Is it time for a Hydraulic Hose Replacement?

Deciding if you should repair or replace a hose relies on one simple rule: when in doubt, replace it. Any type of damage to the length of the hose will compromise the integrity of its walls and can prevent it from holding fluid under a certain pressure, so you’ll want to replace it. Often, the damage occurs at the end of the hose or at a point of connection. Sometimes, to fix it, you’ll need to simply tighten a fitting, but in other cases, you might need to replace the O-ring. In some cases, the fitting breaks but there is enough room left at the end of the hose. If that is the case then you’ll need to remove the fitting and install a new one.

However, in some cases, such as with a brake flex line, the hose should be replaced. Smart preventative services can also be taken, such as installing hose protectors at the first sign of any minor wear. Never open or attempt to repair a hose that is under any type of pressure, and always, always wear appropriate eye and hand protection.

Hoses keep things flowing, and with regular maintenance checks, they can do their job. Now that you know what to look for in a hydraulic hose, you can take smart action at the first sign of any wear or tear.

All About Hydraulics ~ Protect Your Hydraulic Cylinders from Extreme Heat and Cold

Your hydraulic systems are made to handle demanding work conditions and harsh environments. But even the most rugged, high-performing equipment can fail due to certain harsh conditions. In work environments that involve high and low temperatures, the hydraulic cylinders and the components of these robust systems are prone to damage.

Whether you operate mobile or industrial hydraulic equipment, use these tips below to help you understand all about hydraulics and the effects of high and low temperatures on your hydraulic systems and how to protect them from damage.

Protecting Your Hydraulic Cylinders in Extreme Heat

All hydraulic systems generate heat during operation. Extremely high temperatures, however, either from mechanical or environmental sources, can do hard on your hydraulic system.

High Temperatures and Hydraulic Fluid Viscosity

You know how oil will thin out once you add it to a hot pan? Well, heat has the same effect on hydraulic fluid and lubricants. Heat is actually considered a type of hydraulic cylinder fluid contamination because of how it changes the chemical properties which result in lower fluid viscosity and oxidation. The changes heat causes affect how well fluid lubricates the hydraulic cylinder components. Inadequate lubrication increases friction, which makes your hydraulic cylinders and components more prone to damage and wear.

Changes to Hydraulic Cylinder Seals and Hoses in High Temperatures

Extremely high temperatures can alter material properties, causing the seals and hoses to lose resistance to tearing, abrasion, or friction. Seals that have been compromised can introduce moisture, grime, and air into your hydraulic fluid and cause your system to fail. Construction and other applications that involve prolonged exposure to extreme heat should consider Viton, PTFE, or other materials with high-temperature ratings.

Protecting Hydraulic Cylinders in Extreme Cold

All Phase Hydraulics is based in Michigan, so we know cold! We also know that exposure to low temperatures is hard on your hydraulic cylinders, especially the seals and fluid.

Low Temperatures and Hydraulic Fluid Viscosity

Hydraulic fluid has a freezing point of -10 F (-23 C), but even temperatures above the freezing point can change the fluid viscosity. Cold temperatures cause the fluid to thicken, making it more difficult for the fluid to move through your system. Lubricants are also sensitive to extreme temperatures and can harden or lose lubricity in extreme cold.

all about hydraulics

Using hydraulic fluid with a lower viscosity grade can help prevent hydraulic cylinder failure in those colder temperatures. Another way to maintain the fluid viscosity in colder temperatures is using an externally mounted heat source. There are many different types of heating elements you can purchase to keep the hydraulic fluid at the right temperature and viscosity.

How Cold Affects Cylinder Seals and Components

Elastomer and thermoplastic hydraulic seals will shrink and harden under cold conditions, which make the sealed components more prone to leaks. Worn deals cause hydraulic cylinder failure, so it’s crucial to protect your seal components from lower temperatures.

Temperature ratings for hydraulic hoses and seals vary widely because of what material they are made out of. If you plan to use your hydraulic cylinders in frigid temperatures, choose components that have a low temp rating and are compatible with your hydraulic fluid type.

Preventative Maintenance and Using the Right Parts Make a Difference

Performing regular preventative maintenance paired with understanding your mobile equipment application and its operating environment will protect your hydraulic cylinders and other equipment and keep your hydraulic system in pristine condition. Check your fluid levels regularly and inspect your seals and hoses for any signs of wear. Replace bad fluid and worn parts right away will also prevent bigger issues down the road.

What are 3 types of hydraulic pumps

What are 3 Types of Hydraulic Pumps?

When taking a look at hydraulic systems, there are typically 3 types that stand out. The three categories of pumps include gear, piston, and vane, other variants fall under one of these. They are a very critical part of industrial machinery and have the important job of converting mechanical force into fluid energy. Each different pump has a different use, and something that it specializes in. 

Type of Hydraulic Pump #1: Gear Pump

The most commonly used Hydraulic Pump is the gear pump. Called a Gear Pump because it has two rotating gears that turn in the body of the pump. There are two kinds of gear pumps, internal and external which reflect how the system is set up. Internal gear pumps have two different-sized gears that interlock and move within each other. External gears have two of the same sized gears that interlock, reinforced by different shafts. It’s a simple and compact system that can be easier to fix compared to the other systems due to fewer parts.

Gear Pumps are often used in different industries to transfer a variety of high-viscosity fluids. They tend to be used in situations where specific dosages or high pressure is necessary. Output is also not affected much by the pressure which helps with irregular quantities. Some of the fluids used with hydraulic gear pumps…

  • Chemicals
  • Resin
  • Oil 
  • Resin
  • Ink
  • Food Products
  • Paint
Hydraulic Industry News

Type of Hydraulic Pump #2: Piston Pump

The Piston Pump is a more complex system and is found predominantly in the manufacturing world. There are also two main kinds of piston pumps Axial and Radial (there are others, but they are not as popularly used). The difference between the two is that radial piston pumps can be used with all kinds of fluids. Axial piston pumps are used more for their ability to handle high-pressure applications. Both the axial and radial have specific uses and should not be used interchangeably. Piston pumps are able to move liquids without the flow rate being messed up or decreased, they have a wide pressure range.

Axial pumps have a propeller like design that helps them push the flow of fluids in a spiral-like motion. Perfect for producing high flows of fluid and can handle a wide range of tasks. 

Used For: 

  • Dewatering Floods
  • Automotive Air Conditioning Compressor
  • Construction Equipment 

Radial pumps are able to push the flow of fluid outward after creating high amounts of pressure. They do an efficient job at making hydraulic power out of mechanical energy. 

Used For: 

  • Energy Generation
  • Power Steering and Braking
  • Small Airplanes

Type of Hydraulic Pump #3: Vane Pump

Vane pumps have a smooth and low pulsation output and can pass thin liquids at high pressures. They have a robust and compact design while also being lightweight. Vane pumps can execute a steady flow while under different pressures. The pump’s vanes can also add or release tension so they can still reach the pumps walls no matter the viscosity of the liquid that is passing. 

Vane pumps can offer a consistent flow pumping low to medium-viscosity liquids.  Vane pumps also can be used to pump liquids as well as liquids containing solids. They have components that are hardened so that wear and tear takes longer to happen on the equipment.

Used For: 

  • Drink Dispenser 
  • Fridge Coolants
  • Chemical Industry

Wrapping up the 3 Types of Hydraulic Pumps....

Taking in all of this information can be a lot to think about if you’re trying to figure out what pump is best. However, we may have a few questions to ask that may make it easier….

  • What is the desired fluid flow rate?
  • What kind of hydraulic fluid is used in the system?
  • What kind of replacement costs are feasible?
    • Maintenance Fees?
  • What is the maximum operating pressure?
    • High-pressure or low-pressure application?

How Often Should I Refinish the Chrome on my Equipment?

The longevity of hydraulic rechroming services on your equipment largely depends on the condition and environment in which you most frequently work in. Most experts recommend rechroming services every couple of decades in non-wear circumstances, even if you work in harsh conditions. Factors that will require hydraulic rechroming services are commonly determined by:

  • The thickness of your current chrome plating layer
  • How often regular equipment maintenance and proper routine care are performed 
  • The quality of chrome plating materials

The chrome plating not only provides a clean and attractive finish but also is intended to protect your equipment from wear, impact, and corrosion. If you notice early signs of damage or rust then you may need rechroming services sooner than later.

Benefits of Rechroming Services for your Equipment

The rechroming process involves using an electrical current to apply a thin layer of metallic chromium on a surface. When a proper thickness layer of coating is applied to your equipment like hydraulic cylinders, pistons, and other mechanical components, it delivers durable and dependable protection against any excessive wear and corrosion buildup.

Ever wonder why steel and other materials and naturally strong and can withstand heavy duty use yet you still need to invest in chrome refinishing services? Well, by having the chrome plated on your equipment routinely refinished, you can have an extra layer for better wear and rust resistance for improved performance as well as the following rechroming benefits:

  • Added flexibility to apply hard chrome on a range of different materials including brass, copper, and stainless steel.
  • Ability to finish those irregular surfaces and shapes that are hard to reach inside holes, tight spaces, and bores.
  • Increasingly long-term protection capacity with a decreased risk of flaking or delamination during the coating’s lifespan.
  • Low-temperature application, causing little damage or effects on the substrate metal surface.

When you invest in quality chroming services that prevent corrosion, improves wear resistance, and increases the materials hardness- you can expect to minimize additional operating expenses and reduce work downtime.

Hydraulic Fluid 101: Everything You Need to Know When Choosing a Hydraulic Fluid for Your System

Hydraulic Fluid 101: Everything You Need to Know When Choosing a Fluid for Your System

Your pumps may become inefficient or even fail simply because you have used the wrong type of hydraulic fluid. How do you know if you are using the right kind of fluid for your specific hydraulic pump? The answer to that question is it’s dependent on several factors, including the type of pump you have, its maximum operating temperature, its maximum operating pressure, and the type of material that was used to make the pump’s seals.

Hydraulic Fluid

Hydraulic fluid 101: It can serve multiple purposes in a hydraulic system and its components including pumps. The purposes of hydraulic fluid include:

Lubricating Components within the Hydraulic System

Preventing Corrosion

Dissipating Heat

Transmitting Energy

Mainly, the most important factor of the hydraulic fluid is the ability of the fluid to transmit energy, but that can be compromised if too much heat is trapped within the pump, internal components are allowed to corrode, or there is not enough lubrication to prevent surface damage of the internal components.

Why the Hydraulic Fluid is Important for Pumps

The hydraulic pump is known to be the heart of the hydraulic system, and if the wrong fluid is used it can impact the pump’s performance and life expectancy. This being said the use of a fluid that is poorly matched to the pump can lead to a failure that can cause cascading issues throughout the system. Issues that can arise if the wrong fluid is used include:

Excessive Heat Generation

Formation of Sludge and Varnish

Erosion and Excessive Surface Wear

Reduced Component Life

Significantly Reduces System Efficiency

If you notice any of these systems, it may be time to research a better-suited hydraulic fluid for your system.

Hydraulic 101

Key Properties of Hydraulic Fluids

It’s important to understand what properties are important for your particular application before selecting a fluid for your system. The most important characteristics of hydraulic fluids include their viscosity, lubrication, thermal properties, flammability, stability, and foaming.

Viscosity

Viscosity is a measure of the fluid’s resistance to flow, with honey being an example of high viscosity, water being an example of medium-level viscosity, and most gases exhibiting very low viscosity. It is closely related to temperature, with hydraulic fluids becoming more viscous as temperature, with hydraulic fluids becoming more viscous as the temperature drops.

If a hydraulic fluid has a viscosity that is too high, the system will not run efficiently due to the losses involved in overcoming the resistance of the fluid to move. Additionally, damage can occur because components within the system will not be fully lubricated. However, if the viscosity is too low, there can still be some lubrication issues and the fluid might not be as effective at transmitting energy.

Lubrication

A good hydraulic fluid will serve as a lubricant throughout the system, protecting critical surfaces from damage and preventing metal-to-metal contact. In some instances, a hydraulic system or pump might require a hydraulic fluid with some additives to help maintain its lubricity in the presence of high pressures.

Thermal Properties

It’s important to keep in mind the system’s range of operating temperatures so the hydraulic fluid will remain stable and be able to maintain the desired viscosity. This can be a huge issue for equipment that is exposed to outdoor temperatures, especially when the temperatures drop below freezing. In addition, the fluids need to be able to dissipate the heat that is generated by pressure drops and friction.

Flammability

Hydraulic fluid should have a high flashpoint when being used in an explosive or highly flammable environment. The flashpoint is the temperature at which the hydraulic fluid gives off enough vapor to ignite in the air. However, keep in mind that hydraulic fluids can easily ignite if they are discharged under high enough pressure to produce a fine oil mist. Hydraulic fluids should have a non-petroleum makeup or contain a large amount of water If flammability is an issue.

Stability

If possible, the hydraulic fluid should be non-volatile. It should remain both physically and chemically stable in the presence of extreme pressure fluctuations, a wide operating temperature range, and even long-term storage.

Foaming

Another potential issue to look out for with hydraulic fluids is foaming, which occurs when the hydraulic fluid releases trapped gases. Foaming is a result of increased system temperatures as well as a loss of hydraulic fluid as the gases are released.

Types of Hydraulic Fluid

There are three types of basic hydraulic fluid: water-based, petroleum-based, and synthetic. Each type has its own characteristics that make it ideal for certain systems. In addition, there are some fluids that are ideal for applications that can affect the environment.

Water-Based Hydraulic Fluid

This is the oldest type of hydraulic fluid but in modern times is not used as much as the other types. Keep in mind that while water may not be as effective at lubrication, it’s ideal for situations where the possibility of fire is a concern. Water-based fluids tend to be cheaper than synthetic fluids but still more expensive than petroleum-based fluids.

Petroleum-Based Hydraulic Fluid

This type of hydraulic fluid is far more commonly used than water-based fluids and is a cheaper alternative to synthetic fluids. Various types of petroleum-based fluids are different from each other based on how the petroleum products are processed:

Group I: Produced from Solvent Neutral Mineral Oils

Group II: Comprised of Hydroprocessed Base Oil

Group III: Comprised of Hydrocracked Base Oils

Additives comprise about 1% or less of petroleum-based fluids but have a tremendous impact on hydraulic fluid performance. Key additive package components include antioxidants, anti-wear components, foam inhibitors, viscosity modifiers, and rust inhibitors.

Synthetic

This type of hydraulic fluid is man-made and designed specifically to provide high-performance properties that work well in flammable environments. Synthetic hydraulic fluids are the most expensive but work better than other types of fluids when exposed to extreme temperature variations and high pressures. However. Unlike petroleum-based and water-based fluids, they may be incompatible with certain seal materials and can be toxic.

Let's Wrap It Up on Hydraulic Fluid 101:

Unless your system is being used in a very flammable environment, either petroleum-based or synthetic fluids should work well. The viscosity of fluid- which is one of the most important factors involved when selecting a hydraulic fluid- is heavily dependent on both temperature and pressure, with low-temperature working conditions requiring a lower-viscosity fluid. Additionally, the fluid needs to be chemically compatible with the seals used in the pump; this is typically a problem related to the use of synthetic fluids.

All Phase Hydraulics offers maintenance plans to help meet your preventative maintenance needs and goals- and this includes making sure that the most appropriate hydraulic fluid is being used in your system.
