You need to know several things before determining when to replace a hydraulic hose. This includes the routing, chemical compatibility, and the other failures that could be in the system. In addition, you should also know how to prevent work-related injuries.
When replacing a hydraulic hose, it is essential to ensure that the routing is appropriate. Poor routing can damage the hose and cause premature failure. This can lead to costly repairs.
Hoses should be routed in a way that avoids sharp bends. Bends should be gradual and positioned away from areas where there is a possibility of abrasion.
If your hose leaks, find hydraulic hose replacement Charlotte NC to help you throughout the repair process.
A hose bent too sharply can create friction, which can wear out the hose.
Moreover, too sharp a radius can also impede the smooth flow of fluid.
To achieve proper routing, it is recommended to use swivel fittings. These will help you to make a smooth twist-free installation.
You should also avoid routing the hose near high temperatures or abrasive areas. Hoses should also be placed in an area sheltered from external heat.
It would help if you also were sure that the hose you choose is compatible with the fluids in your system. This can be determined by the tube and the seals on your hose.
If you are looking for a new hydraulic hose, you will need to decide whether or not it is chemically compatible with your system. A hose with good chemical compatibility can lead to a hose failure.
There are several ways to determine the chemical compatibility of a hose. The first is to ask the manufacturer. Some manufacturers have an engineering department and access to labs to perform tests. They can provide recommendations on what fluids are compatible with their hoses.
Another way to determine if a hose is chemical compatible is to look at its Material Safety Data Sheet. These documents contain the percentages of individual chemical components and recommend handling and storage practices.
You can also look at the chemical resistance tables. These are a collection of common chemicals and their resistance properties. While they do not guarantee that the hose is resistant, they can be a helpful resource.
The most important thing to remember about a hose’s chemical compatibility is that it needs to be tested with the fluid it is meant to use. Otherwise, you could have a hose that cannot withstand high pressures in your system.
Preventing Work-related Injuries
Hydraulic hoses are critical to the proper operation of a hydraulic system. However, if not replaced regularly, they can lead to costly accidents, damage to property and the environment, and loss of production. In addition, it is essential to train workers on the safest ways to operate the equipment.
Some of the most common accidents involve pressurized fluid that cuts through the skin. A broken hose can put a person at risk of serious injury. Also, a leak can contaminate the surrounding environment.
The best way to prevent a hose burst is to use protective sleeves. These are made of tightly woven polyamide fibers that provide extra abrasion protection. They are also similar to modern body armor.
It is recommended that a company with heavy equipment train operators on the safest ways to operate the machine. This can reduce the number of injuries and casualties.
Likewise, companies with energized power lines should use insulated hoses to cover them. These safety precautions are a good idea, but they can also help ensure that an electrical storm does not damage the line.
Other Failures in the System
Hydraulic hose failure is one of the significant problems that can affect the operation of hydraulic systems. It can result in increased costs, lost productivity, and unscheduled downtime.
Fortunately, a majority of hose failures can be avoided by proper maintenance. In addition to regular preventative maintenance, identifying the most common causes of loss can help you prevent them from occurring in the first place.
The most common cause of hydraulic hose failure is abrasion. Abrasive debris can get inside the hose and cause small cracks in the inner tube, eventually leading to complete loss.
Another cause of hose failure is high temperatures. The elastomer plasticizers will break down or harden in high temperatures. When this happens, the hose will become stiff and break.
High-pressure hydraulic hoses can also cause physical injury to workers. They are prone to abrasion from the surrounding metal edges. For this reason, it is essential to protect them with spacers and protective covers.
