The pre-start inspection step of the slurry pump is an important operation to ensure that the slurry pump is prevented from being damaged when starting. The slurry pump must be checked according to the following steps before starting, otherwise it will easily cause the failure of the slurry pump.
Before starting the slurry pump, the whole unit should be checked according to the following steps
1. The slurry pump should be placed on a firm foundation to withstand the full weight of the slurry pump to eliminate vibration and tighten all anchor bolts;
2. The pipeline and valve should be supported separately. There is a gasket at the flange of the pump. When tightening the connecting bolts, it should be noted that some pump metal linings are higher than the flange. At this time, the bolts should not be tightened too tightly to avoid damage to the gasket.
3. Rotate the shaft by hand according to the direction of pump rotation. The shaft should be able to drive the impeller to rotate without friction, otherwise the impeller clearance should be adjusted.
4. Check the direction of the motor. Make sure that the pump rotates in the direction of the arrow marked on the pump body. Note that the pump is not allowed to rotate in the reverse direction, otherwise the impeller thread will trip, causing damage to the pump.
5. During direct drive, the pump shaft and motor shaft should be accurately aligned. During belt drive, the pump shaft and motor shaft should be parallel, and the position of the sheave should be adjusted to be perpendicular to the sheave to avoid causing severe vibration and wear.
6. A detachable short pipe should be installed at the suction pipe of the slurry pump, and its length should be long enough to remove the pump cover and replace the wearing parts to facilitate the maintenance of the pump.
7. Shaft seal inspection: The pump of the slurry impeller impeller shaft seal is different due to the parking seal structure. Therefore, when the oil cup is installed on the decompression cover, grease must be added through the oil cup. The grease is recommended to be calcium and sodium based.
