The hydraulic oil filter is installed on the suction pipe of the hydraulic pump. This installation method requires the filter to have a larger oil flow capacity and a smaller resistance. Therefore, a coarse oil filter with a lower filtering accuracy is generally used to protect the hydraulic pump. , So that it will not inhale large mechanical impurities. In order not to affect the oil absorption performance of the pump and prevent cavitation, the filtering capacity of the oil filter should be more than twice the pump flow rate, and the pressure loss should not exceed 0.01~0.035MPa.
The hydraulic oil filter is installed on the oil return pipeline. This installation method can frequently remove impurities in the oil. In order to prevent the oil filter from being blocked, the oil can still flow back to the oil tank smoothly, a safety valve should be connected in parallel. Due to the low pressure of the oil return pipe, a low-strength oil filter can be used.
The hydraulic oil filter is installed on the oil pipeline of the hydraulic pump. This installation method can protect other components except the hydraulic pump and the overflow valve. Generally, a fine filter is used. Since the oil filter works under high pressure, the filter element and housing should be able to withstand the working pressure and impact pressure of the system. In order to prevent the overload of the pump or damage to the filter element when the oil filter is blocked, a blockage indicating device or a safety valve can be connected in parallel on the pressure oil line. Installed before the important components, in front of the important components, a separate oil filter can be installed as needed to ensure the normal operation of these components.
The hydraulic oil filter is installed in the bypass filter system outside the system. The large hydraulic system can be specially equipped with an oil filter subsystem composed of a hydraulic pump and a filter to filter out impurities in the oil to protect the main system.
When installing the hydraulic oil filter, pay attention to: Generally, the oil filter can only be used in one direction, that is, the inlet and outlet are not interchangeable.
