Common faults of horizontal slurry pump
What should I do if the horizontal slurry pump encounters the following conditions during use? This article gives a good answer.
Common malfunctions of horizontal slurry pump
1. The pump does not rotate;
2. Insufficient pump flow;
3. Leakage at the packing;
4. The pump vibrates and is noisy;
5. Bearing heating;
6. Short bearing life.
Treatment measures of horizontal slurry pump
(1) The solid and hard sediments in the volute are blocked, and measures can be taken to remove the silt.
(2) If the impeller or the water inlet and outlet pipes are blocked, clean the impeller or pipes. If the impeller is severely worn, it should be replaced. If there is air leakage from the packing port, the packing should be pressed tightly. The conveying height is too high, the loss resistance in the pipe is too large, reducing the conveying height or reducing the resistance. For these failure reasons, Xinfengda Water Pump Factory adopts advanced technology to develop a variety of slurry pumps, which are wear-resistant and anti-corrosive, have high lift, and large flow. , It is widely used in various fields.
(3) If the shaft is different from the refill box, the main reason is that the machining error is large and the installation is incorrect. Attention should be paid to check whether the installation is correct after installation. If the sealing water ring is severely worn, it needs to be replaced with a new one. If the clean water pipe is blocked, the sealing water cannot enter the middle of the packing, causing the packing to wear quickly and cause material leakage. The blocked water pipe should be dredged to keep the sealing water clean.
(4) There are mainly the following 5 reasons: ①The medium density is uneven. The uneven density of the medium causes the pump to vibrate when it is just started. When the pump is turned on normally, the vibration of the pump will disappear. This situation does not need to be dealt with. Just pay attention to blowing the medium with high-pressure air before driving; ② Pump installation Not level. The level of the pump body should be checked during installation and operation. ③There is cavitation, which makes the impeller of the pump unbalanced. The installation height should be lowered, the outlet valve should be reduced to reduce the inlet resistance. ④The intake pipe is uneven. The feeding condition of the pump should be improved to strengthen the uniform stability of the air intake. ⑤The bearing clearance of the pump is large. Excessive bearing clearance will cause the pump to vibrate greatly. In daily equipment operation, you should always pay attention to the condition of the pump. It is found that the pump shaft and the motor shaft are not concentric or the bearing is damaged should be dealt with in time.
(5) There are mainly the following 5 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 cleared. ②The equipment is not well lubricated. The amount of lubricating oil should be adjusted according to the instructions. ③The lubricating oil is not clean and there are impurities in the oil. The bearings should be cleaned and the lubricant should be changed. ④The thrust bearing is in the wrong direction. According to the inlet pressure, adjust the thrust bearing direction. ⑤ The air outlet of the bearing is blocked, causing the hot air in the bearing box to not be discharged, which increases the temperature of the equipment. The air outlet should be cleaned.
(6) There are mainly the following 4 reasons: ① The motor shaft and the pump shaft are not symmetrical or parallel. The motor shaft or pump shaft should be adjusted. If the shaft is deformed or bent, replace the shaft directly. ②The bearing assembly is unreasonable. Reassemble the bearing and axle, or replace the bearing. ③There is friction in the pump or the impeller is out of balance. The friction should be eliminated or the impeller should be replaced with a new one. ④The lubrication is not good. Excessive too little impurities will lead to short bearing life, the bearing should be taken out and cleaned before use.
