Atlan editor told you the precautions for using the lubricating oil filter:

The correct use of the filter can effectively control the cleanliness of the lubricating oil, reduce the wear of the mechanical lubrication parts, greatly reduce the failure rate of the equipment, and then improve the service life of the equipment. The maintenance of filters is the key link.

Since most of the lubricating oil systems are uninterrupted working systems, most of the lubricating oil filters are double-barrel filters. The user should read the instruction manual carefully and maintain it strictly in accordance with the operating procedures.

During work, when dirt blocks the filter element and the differential pressure rises to the set value, the differential pressure transmitter announces a signal alarm, and the filter element needs to be replaced at this moment.

During operation, the operator must first loosen the venting plug of the spare cavity and open the pressure balancing valve. After the liquid fills the spare cavity, tighten the venting plug. Roll the selector valve handle to another station. At this time, the spare cavity starts to work, and the original cavity is closed together. After closing the pressure balancing valve, you can unscrew the vent plug of the original working cavity and the drain plug at the lower part to drain the dirty oil. After that, open the filter cover and take out the dirty filter element. Clean and clean the filter housing and filter cover, check and replace the aging or damaged seal ring on the filter housing, replace with a new filter element and install the filter cover, and screw on the oil drain plug for future use.

Although most products are equipped with a bypass valve in preparation for the signal from the differential pressure transmitter, and when there is no one at the scene or it is inconvenient to stop at the moment, the bypass valve opens only when the differential pressure continues to rise to the agreed maximum value. jobs. However, it should be noted that at this moment the oil is not filtered and cleanliness cannot be guaranteed. Therefore, after the alarm is issued, the filter element should be replaced in time.

When replacing the filter element, care must be taken to prevent dirt from falling into the clean oil cavity to prevent secondary pollution. Since most of the lubricating filter elements are metal mesh filter elements, the dirty filter elements can be cleaned and reused.
