How to choose Hydraulic Hose correctly in hydraulic system
The correct selection of hydraulic hose is related to the normal management of the entire hydraulic control system and the improvement of the procurement cost of enterprises. The following are the factors we choose hydraulic hose(1SN hydraulic hoses ,2SN hydraulic hoses ,4SH hydraulic hoses,4SP hydraulic hoses 6SP hydraulic hoses).
1, hydraulic hose size
The inner diameter of the hydraulic hose is too small, it will increase the flow rate of the working medium in the pipe, so that the system has more heat, efficiency and reduction, and it will produce pressure drop of too much pressure, affecting the performance of the entire management system; Excessive inner diameter will affect the normal operation of the system by increasing the company's procurement cost. When the hose is fixed with a pipe clip or the hose is passed through the steel plate, we should pay attention to the different sizes of the outer diameters of the hose. The use of the hose flow, diameter and flow rate of the relationship between the diagram, you can quickly make a choice of their own appropriate hose diameter.
2, hydraulic hose pressure
Hydraulic hose more pressure, the higher the price. The maximum working pressure of the hose should be determined according to the pressure of the system. Selection not only ensures the normal operation of the system, but also saves the purchase cost. Because of the impact load of the hydraulic system, the maximum working pressure of the hose is generally greater than the maximum working pressure of the hydraulic system, the explosion pressure of the hose is generally 3ー4 times the maximum working pressure.
3, hydraulic hose temperature range
The working temperature of the hydraulic hose is too high or too low, which will affect the life and pressure capacity of the hose. Therefore, no matter how the working state of the hose changes, the ambient temperature can not exceed the temperature limit of the hose. If the temperature is below or above the recommended temperature limit, the performance of the hose may be reduced, leading to hose damage and leakage. Therefore, when the hose is arranged near the heat source, appropriate heat insulation measures must be taken.
