Double-Cylinder Filter

The double-cylinder filter is mainly installed on the oil return line of the hydraulic system. Various kinds of dirt such as abrasive grains generated by various hydraulic components during the working process can be intercepted by setting the oil filter of the return oil line to avoid returning to the fuel tank again. It is again sucked by the hydraulic pump. The allowable pressure difference of the oil return line of the return line is in the range of 0.3 to 0.5 MPa depending on the pressure level. The accuracy is determined according to the requirements of the degree of oil contamination. In the working process, when the single-cylinder filter element is blocked to a certain extent, it is necessary to stop the main machine work to replace the filter element when cleaning or replacing the filter element. This not only wastes time, but also can not meet the continuous working needs of the host. The double-tube filter effectively solves the single The defect of the cartridge filter can be cleaned or replaced without stopping the machine to ensure the normal operation of the mainframe. When a filter element is clogged and needs to be replaced, it is not necessary to stop the main machine. Just open the pressure balance valve and turn the reversing valve. The other filter can work and replace the blocked filter.
