Duplex filters, also called double-barrel return pipeline filters, are composed of two single-barrel filters and two six-way reversing valves, which have simple structure, easy to use, and with by-pass valve and filter core pollution clogging transmitter, in order to ensure the safety of the system.
The double-barrel filter is mainly installed on the return pipeline of the hydraulic system. Various kinds of dirt such as abrasive particles produced by various hydraulic components in the working process can be intercepted by setting the Oil Filter of the return pipeline to avoid returning to the fuel tank again. Inhaled again by a hydraulic pump. The allowable pressure difference of the oil filter in the return pipeline is 0.3 ~ 0.5mpa. according to the different pressure level. The accuracy is determined according to the oil contamination requirement. In the working process, when the filter core is clogged to a certain extent and the filter core needs to be cleaned or replaced, it is necessary to stop the mainframe operation to replace the filter element, which is not only a waste of time but also can not meet the needs of continuous operation of the main engine. The double-barrel filter can effectively solve the defect of single-barrel filter and can clean or replace the filter core without stopping to ensure the mainframe work normally and continuously. When one filter core is blocked and needs to be replaced, it is not necessary to stop the mainframe operation. Just open the pressure balance valve and turn on the reversing valve. The other filter can take part in the operation and then replace the blocked filter element
