How is the hydraulic hose selected?
Introduction to hydraulic hoses:
There are many factors that affect the use of hydraulic hoses. Only in accordance with the correct selection of hose and fittings in accordance with the working conditions, can ensure the reliability and economy of the use of hose. But we must focus on the following factors:
1, Hydraulic Hose size
The inner diameter of the hydraulic hose should be appropriate. Too small pipe diameter will increase the flow rate of the medium in the pipeline, so that the system heats up, reduces efficiency, and will produce excessive pressure drop, affecting the performance of the whole system. If the hose is fixed with a tube clip or the hose passes through the steel plate and other spacers, it is also important to pay attention to the outer diameter dimensions of the hose.
2, Hydraulic Hose working pressure
The dynamic working pressure of the hydraulic hose in the data refers to the maximum pressure allowed by the hydraulic hose during continuous operation. In accordance with the safety factor of the hydraulic hose as set by the relevant international standards, the recommended working pressure is usually about one quarter of the minimum blasting pressure value of the hydraulic hose.
3, Hydraulic Hose temperature range
The user should use the hose within the temperature range allowed by the hydraulic tube quality specification. If the operating temperature exceeds this range, it will affect the life of the hydraulic hose, and its pressure capacity will be greatly reduced. Hose guards are recommended for systems where the working environment temperature is too high or too low for a long time.
