What Adjustments are Required Before Operation of the Slurry Pump

Before starting the slurry pump, the entire unit should be checked according to the following steps.

(1) The slurry pump should be placed on a solid foundation to bear the full weight of the slurry pump to eliminate vibration, and tighten all anchor bolts.

(2) Pipes and valves should be supported separately. There is a sealing gasket at the flange of the slurry pump. When tightening the connecting bolts, you should pay attention to the fact that some metal linings of the slurry pump are higher than the flange. At this time, the bolts should not be overtightened to avoid damaging the sealing gasket.

(3) Turn the shaft in the direction of rotation of the slurry pump by hand. The shaft should be able to drive the impeller to rotate and there should be no friction. Otherwise, the impeller clearance of the slurry pump should be adjusted.

(4) Check the motor rotation and ensure that the slurry pump rotates in the direction of the arrow marked on the pump body. Note that the slurry pump is not allowed to rotate in the opposite direction, otherwise the impeller thread will trip, causing damage to the slurry pump.

(5) In direct-coupled transmission, the pump shaft and motor shaft should be accurately aligned. In belt transmission, the pump shaft and motor shaft should be parallel, and the position of the sheave should be adjusted so that it is perpendicular to the grooved belt to avoid severe vibration and wear.

(6) A detachable short pipe should be installed at the suction pipe of the slurry pump. Its length should be sufficient to dismantle the pump cover and replace wearing parts to facilitate the maintenance of the slurry pump. The length is shown in the overall dimension drawing of each slurry pump.

(7) Shaft seal inspection: Due to the difference in the parking seal structure of the slurry pump with the auxiliary impeller shaft seal, when an oil cup is installed on the decompression cover, grease needs to be added through the oil cup. The recommended grease is calcium sodium. base grease.

Before starting the packing seal slurry pump, you should open the shaft seal water and check whether the amount of shaft seal water and water pressure are appropriate. Adjust the tightening screw of the seasoning gland to adjust the tightness of the packing. Adjust the shaft seal water from the The amount of leakage should be drop by drop. If the packing is too tight, the sleeve will easily heat up and consume power. If the packing is too loose, the amount of liquid leakage will be too large.
