How to choose the right hydraulic hose? Hydraulic hose selection needs to pay attention to several points:
1. Size: The inner diameter of the hose refers to the inner diameter of the hose (not the outer diameter)
2, temperature: temperature refers to the medium temperature rather than working environment temperature. But saying that the operating temperature exceeds the technical characteristics of the hose may lead to the following situation:
Give way
(1) Reduce the service life of the hose (high temperature)
(2) Affect the mechanical properties of the hose (low temperature)
3. Application: Mainly speaking, the entire hydraulic system is in the actual working environment.
4. Medium: The inner glue layer, outer rubber layer and pipe joints must have good compatibility with the medium in contact. (chemical compatibility with media)
5, pressure: mainly refers to the following kinds of pressure: working pressure, pulse pressure, peak pressure, test pressure, burst pressure.
6. Connection of two kinds of thread at the end of the joint: The end of the tube is usually determined by the port of the equipment to which it is connected, and the origin of the equipment has a great influence on the type of joint.
7, delivery status: The delivery time of the hose will not exceed 2 years.
8, other unpredictable situations:
A. Arrangement of hose route, whether pipe clamp is needed
B. Whether it is an oil/gas suction condition
C. Whether the use environment of the hose needs to wear
D. Does the hose need to be anti-static

While paying full attention to the above requirements, special attention is also needed. What hydraulic hose is selected for the hydraulic system is used. The most important thing is to see how the actual operating conditions are, because of the poor workmanship. Under the circumstances, the working status and time of the same type of hose are different.
