Background

Various pumps are important power equipment for offshore oilfield medium transportation, and a filter screen for removing impurities is usually arranged at an inlet of each pump so as to ensure the stable operation of the pump. However, after the filter screen is used for a period of time, the filter screen is easily blocked by particles in the medium, so that the over-liquid capacity of the filter screen is reduced, and the efficiency of the pump is further reduced; in severe cases, the pumps may not operate normally or be damaged. Especially for the most common centrifugal pump, due to the filth blockage of the filter screen, the liquid supply at the suction port is easy to be insufficient, and the pump stop is caused. The pumps in the critical flow path have serious consequences if the pumps are suddenly stopped. Therefore, in one-line production, pump filter cleaning is a relatively routine and very important task.

At present, on the cleaning of a filter screen, an offshore platform basically depends on manual cleaning, and the following three modes are mainly adopted: 1. washing by externally connecting high-pressure water and a water gun head; 2. scrubbing by using diesel oil; 3. and (5) adopting the air pressure of a public gas station for flushing. However, the three methods have large workload, so that the dirt of the filter screen cannot be completely cleaned, and time and labor are wasted; moreover, because no protective device is arranged, the cleaned water and diesel oil are easy to scatter to pollute the deck; the cleaning media are as follows: the produced water and diesel oil often cause harm to human bodies of operators.
