Correct selection of rubber hydraulic hose can ensure the safety of the entire hydraulic system.

The correct choice of hydraulic pipe should pay attention to the following aspects:

First of all to know the product request, Based on the request , then we can clarafiy the working pressure , inner diameter, outer diameter, conveying medium, use environment, service life, length size, minimum bending radius of the rubber hose .

1. The maximum working pressure of the hose should be bigger than the actual working pressure. The higher the pressure , the higher the price.

2. The inner diameter of the pipe should ensure the medium can be smoothly transmitted , not blocked;The outer diameter of the hydraulic hose should not be too large or too small to ensure normal assembly.Pay attention to the outside diameter of the hose when the hose is clamped or passed through a shim such as a steel plate

3. The medium of transmission is hydraulic oil, then it is necessary to choose the resistance of hydraulic oil

4.  whether open air, light time, friction, external temperature,should according to the working environment .The working temperature of the commonly used hose is -40℃ -- 100℃,  highest temperature is 125℃. should consider the life of  hose and replacement of the difficulty and cost.Besides, the length of the hose should according to the specific u, neither to excessive bend or be in a state of strong tension.

5.  Should pay attention to the bending radius , and calculate the bending radius minus the length of the joint buckle.Determine the appropriate minimum bending radius, so as to make the normal use of hydraulic hose environment does not exceed the minimum bending radius.If the bending radius of the hose is too small, it will reduce the pressure capacity of the hose and affect its service life.
