1, size: hose inner diameter 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 the operating temperature that exceeds the technical characteristics of the hose may lead to the following situations:
1) reduce the service life of the hose (high temperature)
2 ) affect the mechanical properties of the hose (low temperature)
3, application: the main said is the entire hydraulic system In the actual work 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 the medium)
5. Pressure: Mainly refers to the following kinds of pressure: working pressure, pulse pressure, peak pressure, test pressure, and 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: hose delivery time will not exceed 2 years.
8, other unforeseen circumstances:
A, the arrangement of the hose line, whether tube clamp
B, whether the condition suction / gas
C, hose wear environment need
D, if required antistatic hose
Precautions of hydraulic hose when it is assembled
The operator must wear safety protective clothing, including gloves, rubber boots, eye shields, and the equipment to be used mainly to protect the safety of the operators.
To ensure the work zone is safety and orderly.
To check each hose joint is firm.
When not in use, and do not make hose in pressure state. Shut off pressure to extend the service.
