Shishui Shishui Industrial and Mining Pump Industry: Common Faults and Treatment Methods of Slurry Pumps
The Shijiazhuang stone pump industry describes the common faults and treatment methods of the slurry pump during use as follows: (1) The slurry pump does not turn; (2) The pump has insufficient working flow; (3) The packing seal has leakage; (4) The pump body is vibrating and there is noise; (5) The bearing is hot and hot; (6) The bearing has a short service life. Treatment measures: (1) Check whether there is solid and solid sediment siltation in the volute, and measures to remove silt can be taken. (2) Check the impeller or the inlet and outlet pipes for blockage. Wash the impeller or piping. If it is found that the impeller wear is serious, the method of replacing the impeller should be adopted. If the packing port leaks, the packing should be pressed. If it is found that the conveying height is too high, the resistance loss in the tube is too large, reducing the conveying height or reducing the resistance. (3) Check whether the shaft and the filling box are installed with different axes. The main cause of this problem is the large machining error and incorrect installation. Care should be taken to check that the installation is correct after installation. If the seal ring is found to be severely worn, a new water ring needs to be replaced. If the sealed water pipe is blocked, the sealing water cannot enter the middle of the packing, causing the packing to wear quickly, resulting in leakage. The blocked water pipe should be unblocked to keep the sealed water clean. (4) There are five main reasons: 1) The density of the slurry is not uniform. Uneven density of the slurry will cause vibration when the pump is just started. When the pump is normally turned on, the vibration of the pump will disappear. This situation does not need to be treated. Just before the pump is turned on, pay attention to the uniformity of the slurry with high pressure; 2 pump The mounting base is not level. The level of the pump body should be checked during installation and operation. 3 There is cavitation, which makes the impeller of the pump unbalanced. The installation height of the pump should be reduced, the outlet valve should be adjusted to reduce the inlet resistance. 4 The suction tube is not evenly fed. The feed of the pump should be improved to enhance the uniform stability of the incoming leaves. 5 pump bearing clearance is large. If the bearing clearance is too large, the pump will vibrate. Check the operation of the pump during daily use. It is found that the pump shaft and motor shaft are not concentric or the bearing is damaged.
(5) There are five main reasons: 1 If the cold water is not turned on or the cooling water tank is blocked, the cooling water function should be turned on or the cooling water channel should be dredged. 2 equipment lubrication is not good. The amount of lubricant should be adjusted according to the instructions. 3 The lubricating oil is not clean and there are impurities in the oil. The bearings should be cleaned and the lubricant replaced. 4 thrust bearing direction is wrong. Adjust the thrust bearing direction for the inlet pressure. 5 bearing air outlet blockage, the hot air inside the bearing housing can not be discharged, so that the temperature of the equipment rises. The air outlet should be cleaned up.
