一是離線沖洗即建立獨立于液壓系統以外的臨時沖洗泵站，進油用粗過濾器，回油用精過濾器，原因是回油壓力較低而且脈動不大。其優點是沖洗泵站獨立于液壓系統之外，對設備自身的安全不會產生影響，另外還可以在沖洗設備上添加加熱器提高沖洗效果。
二是利用液壓系統自身的工作泵站作為沖洗泵站，包括利用本泵過濾器，含隨機帶來的濾芯加熱器等設備，通常稱之為在線沖洗。它可以節省大量的設備和勞力成本，適用于管道少的小型液壓系統，但要充分考慮液壓設備自身的技術參數，確保系統設備的自身安全，施工技術要求較高。
對沖洗方案的選擇原則是，在保證安全的原則下首先考慮用本泵沖洗，在本泵沖洗能夠達到沖洗所需要的流量和壓力的情況下，可采用本泵沖洗，否則就要采用離線沖洗。
武鋼液壓站各試驗臺系統本泵能夠提供的最大流量，經過與沖洗系統所計算的最小流量進行比較可知油缸馬達試驗臺，油泵試驗臺和液壓閥試驗臺的液壓管道必須采用離線沖洗的方式，而伺服閥試驗臺和大流量伺服閥試驗臺則采用本泵沖洗就能完成沖洗要求。
There are usually 2 options for the establishment of a circulating irrigation pump station.
First, the off-line flushing is to establish a temporary flushing pump station outside the hydraulic system, and a coarse filter for oil inlet and a fine filter for oil return. The reason is that the oil return pressure is low and the pulsation is not large. The utility model has the advantages that the flushing pump station is independent of the hydraulic system, and has no influence on the safety of the equipment itself, besides, the heater can be added to the flushing device to improve the flushing effect.
Two is the use of the hydraulic system itself, the pump station as a flushing pump station, including the use of the pump filter, including random filter, heater and other equipment, often referred to as online irrigation. It can save a lot of equipment and labor costs for small hydraulic system in the pipeline is less, but to fully consider the technical parameters of its hydraulic equipment, ensure the equipment safety system, the construction of higher technical requirements.
The choice principle of flushing plan is to ensure the safety of the principle of first consideration flush with the pump, the pump in flushing can achieve the required flow rate and flushing pressure, the pump can be used to wash, otherwise you will use offline flushing.
The maximum flow test system of the hydraulic pump can provide Wuhan station, after comparing the cylinder motor test bench and minimum flow flushing system to calculate the hydraulic pipeline pump test and hydraulic valve test rig must be used offline flushing mode, and the servo valve test bench and large flow servo valve test bench is used this pump can finish washing washing requirements.
