Hydraulic Hose Filter System Design

The hydraulic hose must match the highest pressure capable in the hydraulic filters system, which is usually the pressure given by the pump. However, of course there is a component of increased pressure on the engine that can be much higher than hydraulic reliefs or pump pressure capacity, especially when the cylinder intensifies the pressure produced. Special attention must apply when designing a system with a flow divider because of this effect.

Hose usually has a rating of burst 4 times the pressure rating so that even though the lower ranking can work for a short time, they will be exhausted and then fail in a shorter time. A good idea to then see a failed hose to ensure it will match the pressure ranking of the hydraulic flow circuit. Sometimes people can easily make hydraulic hose assemblies from the wrong type of hose and will not realize it only to failure. This can happen even from the factory.

High pressure hydraulic lines for cellular equipment usually come in some amount of pressure range. There are exceptions for this, especially with those producers who try to enter the market share by offering different benefits to their customers. a 6000 psi pressure tube can usually be found on closed hydro-static loop circuits such as path drive and higher horsepower drives used in drilling, excavation equipment, etc.

Furthermore, there is a 4000-PSI interval used in several open piston loop pumping systems involved in manufacturing. The most common hydraulic hose found in the industry is the 3000 PSI ranking hose, which is common with a tooth pumping circuit used in correlation with high pressure cylinders and dental motor systems. There are many 1500 interval and lower PSI rankings for the return path and other special case applications. Most of these hydraulic filters are used to supply valves and then return to the oil cooler, hydraulic filter, and oil reservoir. If you ask questions, why not use the highest hydraulic tube on everything on the oil circuit; That's because of a higher cost.

Often, steel lines have advantages compared to hydraulic rubber hose due to greater heat rejection, better abrasion resistance, fire resistance, and better pressure resistance. If there is a long distance running to the machine, it can be a smart idea to install a solid steel line that is bent to the shape to replace the hydraulic oil circuit.

The hose develops with each pressure cycle. This interval usually has a wrinkled steel tip is also called hydraulic fitting. The failure of the tube fatigue will usually occur near the end of the hose because the rubber tube and the tip of the steel fitting hose will expand at a different rate. The end of the hydraulic hose can also be vulnerable to the wrong crimp process if the crimping technician is not trained. Steel hydraulic lines will not be asflected hydraulic hose, so be careful not to load any component that is connected when installing steel filter to the machine.

During the manufacture, the hydraulic hose is the last thing done on the engine when built. When technicians and engineers are rushed and under the working pressure to meet the deadline, it is hydraulics and hydraulic hoses that usually suffer. Overtime, after complaints back from customers or if you have good technicians, they can repay the hose and hydraulic equipment to provide the best service from components.

Conclusion

From the above discussion, we can conclude that hydraulic hoses are an important part of any hydraulic system. However, they need to be carefully selected based on the specific application and requirements. Furthermore, regular maintenance and inspection is necessary to ensure that they are in good condition and functioning properly.
