Hydraulic hose is a type of hose that is superior to ordinary hoses in both performance and function. It is mainly composed of an inner rubber layer, a middle rubber layer and several coils of steel wire. The inner rubber layer allows the conveyed medium to withstand a certain pressure and prevents the steel wire from being corroded. The outer rubber layer is to prevent the steel wire from receiving other types of damage. The clever combination of the two allows the inner steel wire layer to play a certain reinforcing role as a skeleton material. It can not only use hydraulic power to transport media such as water and gas, but also transmit high-pressure media such as oil, so that the liquid can circulate continuously and energy can be transmitted. So what factors do we need to consider when choosing a hydraulic hose?
The hydraulic system transmits energy by transmitting fluids of different pressures and flows. In order to minimize pressure loss and avoid system damage caused by excessive heating, the size of the hose and connector must be appropriate.
The selection of hydraulic hoses and connectors must ensure that the maximum working pressure of the hose assembly is equal to or greater than the maximum working pressure of the hydraulic system, and the pulse working pressure or peak pressure of the system must be less than the maximum working pressure of the hose. The applicable range of hydraulic hose pressure is often overlooked by designers and hose assembly manufacturers. In fact, the pressure range of the hose assembly is determined by the lowest working pressure of each component of the hose assembly, and the pressure range of many joints is much smaller than that of the pipe.
When selecting a hydraulic hose, the medium transported inside the hose and the ambient temperature outside the hose should be carefully considered. It is said that under the combined conditions of high temperature and high pressure, the service life of the hose will be reduced. We can choose a high-temperature resistant hose with the last character of the hose code as 6; low temperature will reduce the softness of rubber products. Generally, the lowest temperature of a hydraulic hose assembly refers to the lowest temperature that can be adapted to the outer surface of the hose without reducing the bending performance of the hose.
Doctors are some factors that we need to consider when choosing hydraulic hoses. In fact, when purchasing hydraulic hoses, you also need to pay attention to many related selection skills. You must know that the smaller the bending radius of the hydraulic hose is not the better. We must test whether it is deformed in a certain installation environment before using it.
