The correct use of the filter can effectively control the cleanliness of the smooth oil, reduce the wear of the smooth parts of the machine, greatly reduce the failure rate of the equipment, then increase the service life of the equipment. maintaining the filter is the key link.

Since most of the lubricating oil system is an uninterrupted operation system, the lubricating oil filter is mostly a double-tube filter. Wholesale users of multi-stage filters should carefully read the operating instructions strictly follow the operating procedures for maintenance.

In the process of operation, when the filter element is blocked by dirt the pressure difference rises to the set value, the pressure difference indicator will signal an alarm, the filter element needs to be replaced at this moment.

During operation, the operator must first loosen the bleed plug of the backup cavity open the pressure balance valve, tighten the bleed plug after the liquid fills the backup cavity. Roll the reversing valve handle so that it is in another station. At this time, the spare cavity starts operation, the original operation cavity is closed at the same time. After closing the pressure balance valve, you can unscrew the vent plug of the original working chamber the lower oil drain plug to drain off the dirty oil, then open the filter cover take out the dirty filter element. The multi-stage filter company cleans the filter housing filter cover, checks replaces the aged damaged sealing ring on the filter housing, replaces the filter element with a new filter element, installs the filter cover, screwed on the oil drain plug for use.

Although most products are equipped with a bypass valve to prepare for the signal the differential pressure transmitter, when there is no one on site it is inconvenient to stop the machine at the moment, the bypass valve will only open when the pressure differential continues to rise to the maximum allowed to ensure continuous operation of the system . But it should be noted that the oil is filtered at this moment, the cleanliness cannot be guaranteed. Therefore, the filter element should be replaced in time after the alarm of the signal transmitter.

When replacing the filter element, be sure to prevent dirt falling into the clean oil chamber to avoid secondary pollution. Since most of the filter elements used for smoothing are metal mesh filter elements, the dirty filter elements can be cleaned reused.
