Technology information for hose assembly

Lots of factors can impact the use of rubber hose assembly. Choosing the rubber hose and couplings rightly according to the working situation, could ensure the reliability and economy of the hose.

1. Size of rubber hose

The inner diameter of rubber hose should be suitable. The too small radius will speed up the medium flowing in the pipeline, which makes the system heat, decreases the rate, generates overlarge pressure-reduction, and then impacts the system. More over, when rubber hose is stabled by pipe clamp or the rubber hose crosses through the steal plate, please notice the size of outside diameter of the rubber hose.

2. Working pressure

The dynamic working pressure of the rubber hose in this construction is the highest pressure when continuously working. According to the security coefficient ordained by the international standard of hydraulic pressure, the working pressure advised is one-forth of the lowest burst pressure of the rubber hose.

3. Impulse pressure and fatigue life

The choice of the rubber hose is according to the highest pressure of the hydraulic pressure system. Due to the dynamic pressure value of the hydraulic pressure system. It will generate the impulse pressure that exceeds the highest pressure value of system. However, the impulse pressure will not heavily impact the fatigue life because the system has the flooding value. For the hydraulic pressure system with high frequency impulse pressure, please use the rubber hose which is especially endured by the impulse.

4. Range of temperature

The user should use the rubber hose under the range of temperature limited by the quality criterion. When the working temperature exceeds the range, the using life will be impacted and the enduring pressure will be decreased significantly. For the system working long under too high or too low temperature, the rubber hose jacket should be used.

5. Chemistry consistent

The user should ensure that the rubber hose inside, rubber hose outside, fitting and o-type sealing ring of the chosen rubber hose assembly is consistent with the medium when using the special pressure medium.

6. Bend radius

Pay attention to the minimum bend radius when installing the rubber hose assembly. The too small bend radius will decrease the pressure endurance of the rubber hose and also reduce its using life.

7. Friction

Please attache the spring jacket outside the rubber hose if it always touches or rubs with the rigid things.
