鉆式抽沙船的進出水管路應(yīng)有承載支撐，避免管路重力施加于泵體。管路安裝應(yīng)從泵進出口法蘭向外延伸，并立即做好支撐定位。泥沙泵工作時必須對填料室注入高壓清水以保護軸封組件。主泵在正常工作時不得關(guān)閉高壓清水泵。鉆式抽沙船清水壓力應(yīng)大于泥沙泵工作壓力。填料室組件在沒有高壓清水保護的情況下會很快磨損。

The drill water pipeline pump dredger should avoid pipeline bearing support, gravity imposed on the pump body. Pipeline installation should be extended from the pump inlet and outlet flange, and immediately do a good job supporting positioning. The mud pump must work to protect the high pressure water injection packing chamber seal assembly. The main pump in normal operation shall not be shut down the high pressure water pump. Drilling pumping sand water pressure should be greater than the pump working pressure of sediment. Packing chamber assembly in the absence of high pressure water to protect the case will soon wear.
