HDYRAULIC HOSE PIPE EN 8564SH WIRE SPIRAL REINFORCEMENT

Hose in the use and design should pay attention to the following matters

The bending radius should not hose is too small, the general should not be less than < hydraulic hose

assembly features Technical Regulations > in the value.

The hose assembly shall be a straight part connected with a pipe joint, two times the length of the pipe

diameter should not be less than

2. The length of hose assembly, hose should be taken into account in the oil pressure, length contraction

deformation will occur, the general contraction for length 3 ~ 4%. so the hose assembly is installed, is not

allowed in a tight state.

3, the hose assembly should be installed to ensure no torsional deformation. The joint axis of the tube

should be placed in the plane. To avoid damage to each other during exercise.

4 ends of hose, hose should avoid contact and friction with the sharp corners of the mechanical parts, to

avoid pipe damage

1, pressure hose specified working pressure is usually not less than the maximum pressure of the

system, not only in constant use, allowed increased by 20%; for the frequent use, often to reduce the

torsional shock pressure 40%. system if higher than the specified working pressure hose, not only

reduces the service life of the hose, and may lead to people accidents.

2, temperature, fluid temperature and ambient temperature, whether it is stable or transient, shall exceed

the temperature limit of the hose, the recommended temperature is lower or higher than the hose, hose

can reduce the performance caused by the hose is damaged, causing leakage.

3, fluid compatibility: fluid in the hose. Product samples shall comply with the "use" made in the

regulations, beyond the prescribed use can not guarantee that the service life and the safety of the pipe.

At the end of

4, the appropriate connection: as the nut is connected The utility model has the advantages of convenient

operation and low cost, and is widely used, but when the vibration is large, the nut loosening problem is

taken into account.
