The purpose of the erosion is to prevent impurities are accumulated, to prevent the air bag formed to maintain and improvelubrication, when the washed liquid temperature is low, both the cooling effect. Erosion of the main methods are as follows:

　　One, within the erosion

　　1, positive scour

　　Features: (1) utilization of the host to be sealed by the export side of the pump introduced through the pipe sealed chamber.

　　(2) Application: for cleaning fluid into the P1, slightly larger than P coolers, filters, etc. When the temperature is high or impurities, canbe set in the pipeline.

　　2, anti-erosion

　　Features: (1) utilization of the host to be sealed, introduced by the export side of the pump seal chamber, after scouring through the pipeline to flow back into the pump inlet.

　　(2) Application: for cleaning fluid, and P

　　3, the whole washed

　　Features: (1) utilization of the host to be sealed by the export side of the pump through the pipeline the introduction of the sealed chamber, washed and then administered road to flow back into the pump inlet.

　　(2) Applications: cooling effect is better than the first two for the cleaning fluid, and P1 and P in and P out close to.

　　Second, the outer erosion
