How to select rubber hydraulic hose

How to select rubber hydraulic hose

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

  • Please choose the suitable size of hose fitting for hose.
  • When the joint tube end portion is inserted into the hose, paint the hose and pipe tail in oils, do not roast with fire. If it’s unable to insert, heat the hose with hot water and then it will be available insert into the connector.
  • Please make sure the serrated tube tail portion of the connector is completely inserted into the hose.
  • Do not use a joint that can be pushed into for one time, it may cause hose rupture.
  • Please avoid using excessive ligation wire, please choose a special sleeve or cable tie.
  • Avoid using injurious or rusty joints.

Security matters:

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.
