When we use the slurry pump, it is unavoidable that accidents will occur, resulting in the normal use of slurry pump. So, when we are facing the slurry pump failure, how should we find out the cause of the failure and propose solutions? Please follow the Xiaobian to have a look at it together! uuuuuuuuuu
What are the common faults of slurry pump? Introduce the methods to deal with the faults of slurry pump
(1) Failure of slurry pump
(1) the pump does not turn.
(2) insufficient pump flow;
(3) leakage of filler;
(4) Vibration and noise of the pump;
(5) bearing heating;
(6) Short life of bearings.
(2) Treatment of Slurry Pump Faults
(1) Solid sediment in the vortex shell is silted up, and measures for removing silt can be taken.
(2) If the impeller or the inlet and outlet pipelines are blocked, the impeller or pipeline can be cleaned. If the impeller is worn seriously, it should be replaced. If the filler leaks, the filler should be compressed. For these reasons, Yantai Xinhai Mining Machinery adopts advanced technology to develop a variety of slurry pumps, which have the advantages of abrasion resistance, anticorrosion resistance, high lift and large flow rate, and is widely used in various fields.
(3) If the axis is different from the feeding box, the main reason is that the processing 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 worn seriously, a new water ring should be replaced. If the sealed water pipes are blocked, the sealed water can not enter the middle of the packing roots, resulting in rapid wear and tear of the packing roots, leading to material leakage. The blocked water pipes should be dredged to keep the sealed water clean.
(4) There are five main reasons: (1) the density of medium is not uniform. The uneven density of medium causes the vibration of the pump when it is just started. When the pump is normally opened, the vibration of the pump will disappear. This situation does not need to be dealt with, but before driving, pay attention to the medium with high-pressure air blowing; 2) the installation of the pump is not level. The level of pump body should be checked during installation and operation. The impeller of the pump is unbalanced because of cavitation. The installation height should be reduced, the outlet valve should be adjusted to reduce the import resistance. (4) Intake of inhalation tube is not uniform. The feed condition of the pump should be improved and the uniform stability of the intake should be strengthened. _Large clearance of pump bearing. The excessive clearance of bearings will lead to large vibration of the pump. In the daily operation of equipment, we should pay attention to the situation of the pump at any time, and find that the pump shaft and motor shaft are not centralized or the bearing damage should be handled in time.
(5) There are five main reasons: (1) If the cold water is not opened or the cooling water tank is blocked, the cooling water function should be opened or the cooling water channel should be dredged. The lubrication of equipment is not good. The amount of lubricating oil should be adjusted according to the instructions. (3) The lubricating oil is not clean and there are impurities in the oil. Bearings should be cleaned and lubricants changed. 4. The thrust bearing is not in the right direction. According to the inlet pressure, adjust the direction of thrust bearing. The blockage of bearing outlet results in that the heat in the bearing box can not be discharged, which makes the equipment temperature rise. The outlet should be cleaned up.
(6) There are four main reasons: (1) The motor shaft and the pump shaft are asymmetrical or not parallel. The motor shaft or pump shaft should be adjusted. If the shaft is deformed or bent, the shaft should be replaced directly. (2) The assembly of bearings is unreasonable. Load bearings and axles, or replace bearings. (3) There is friction in the pump or the impeller is out of balance. Friction should be eliminated or new impellers should be replaced. (4) lubrication is not good. Excessive amount of impurities will lead to short service life of bearings. Bearings should be removed and cleaned before use.
