Hydraulic Fittings Suppliers Introduces The Requirements For Th
-
Hydraulic Fittings Suppliers introduced that if 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 rate and a smaller resistance. Therefore, coarse oil filters with lower filtration accuracy are usually used to protect the hydraulic pump so that it will not suck in a large amount of mechanical impurities. In order not to affect the pump's oil absorption performance and prevent cavitation, the filtering capacity of the oil filter should be greater than twice the pump flow rate, and the pressure loss should not exceed 0.01~0.035MPa.
If installed on the oil return pipeline, this installation method can often remove impurities in the oil. In order to prevent the oil filter from clogging and the oil can still flow back to the oil tank smoothly, a safety valve should be connected in parallel. Since the pressure in the oil return pipe is low, a low-strength oil filter can be used.
If it is installed on the oil pipeline of a hydraulic pump, this installation method can protect other components except the hydraulic pump and the overflow valve, and a fine filter is usually used. As 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 pump from overloading or damaging the filter element when the oil filter is blocked, a blockage indicating device or a safety valve can be connected in parallel to the pressure oil pipe. Installed before important parts, before important parts, you can install a separate oil filter as needed to ensure the normal operation of these parts.
During installation, it should be noted that the hydraulic oil filter can only be used in one direction, that is, the inlet and outlet cannot be interchanged.
