What is the reason for the leakage of dirty oil pipe of Nanjing Oasis 206 oil separator?

According to the query, Douding.com shows.

1. First, the sliding chassis is stuck or the sliding chassis and the separating cylinder cover cannot stick together. The main reason is that the sliding chassis is worn for a long time, or the sealing ring at the upper end of the sliding chassis is invalid, and the transmission gear and bearing are excessively worn, so that the vertical shaft sinks.

2. Secondly, the slip ring can't move up, which leads to the blockage of the sealing water cavity. The main reason is that the small hole on the separator is blocked, the spring below the slip ring is seriously invalid, and the plastic plug above the slip ring is not tightly sealed.

3. Third, insufficient working water pressure in the working water system, insufficient water in the water tank, leakage of compressed air, leakage of working water pipeline, dirty blockage or filter screen blockage will make the working water pressure insufficient and the sealing water insufficient.
