During the use of a dual filter, when the filter element of one of the filters is blocked, resulting in a pressure difference of 0.35mpa between the inlet and outlet, the transmitter sends a signal. At this time, rotate the directional valve to make the backup oil filter work, and then replace the blocked filter element. When the clogged filter element cannot be replaced in a timely manner due to certain reasons, causing the pressure difference between the inlet and outlet to further increase to 0.4 MPa, the bypass valve will automatically start working to protect the normal operation of the filter element and system. However, users should replace the filter element as soon as possible.
The duplex oil filter DQ150AW25H1.0S is used in the filter to remove impurities in the system oil, keep the oil returning to the tank clean, and facilitate the circulation of the oil flowing through the filter.
