Horizontal slurry pump product common fault solution

Common slurry pump failures:

(1) pump is not turned;

(2) the pump flow is insufficient;

(3) packing leak;

(4) the pump vibration and noise;

(5) bearing heating;

(6) bearing life is short.

Measures:

(1) eddy shell solid hard sediment silting up, can adopt measures to remove blockages.

(2) such as impeller or in and out of the water pipe road blocks, can adopt clean impeller or pipeline. Such as impeller wear serious, should be taken to change. Such as packing leakage, pressure filler. Conveying height is too high, tube resistance loss is too big, reduce transmission height or decrease resistance, according to these the cause of the problem, yantai xin sea mining machine adopts advanced technology research and development of a variety of slurry pump, wear-resistant anti-corrosion, high head, large flow etc, and widely used in various fields.

(3) such as the axis and axis of container is different, the main reason is that great error in the processing, installation is not correct. Should be paid attention to in the inspection after installation is correct. Such as seal water ring wear serious, need to replace new water ring. Such as sealing pipe blockage, seal water not deal among packing packing wear fast, cause leakage of material. For plugging pipe dredge, keep the seal water clean.

(4) basically has the following five reasons: (1) uneven medium density. Medium density caused by uneven pump vibration occurs has just started, when the pump is normal after opening, the vibration of the pump will disappear, does not need to handle this kind of situation, just before driving, pay attention to the medium with the high-voltage wind; (2) the installation of the pump is not level. In the process of installation and operation should check the level of the pump body. (3) a cavitation, make the pump impeller imbalance. Should reduce installation height, the small water valves, import less resistance. (4) uneven suction inlet. Should improve pump feed situation, strengthen the uniform stability of the intake. (5) pump bearing clearance. Bearing clearance will lead to pump vibration is big, should pay attention to the pump at any time in the daily operation of the situation, found that different heart or pump shaft and motor shaft bearing damage should be handled in a timely manner.

(5) basically has the following five reasons: (1) not open cold water or blockage in a cooling water tank, should open the function of the cooling water or cooling waterway dredging. (2) equipment lubrication is not good. Should be in accordance with the manual adjustment quantity of lubricating oil. (3) lube oil is not clean, impurities in oil. Should clean bearing, lubricating oil. (4) thrust bearing direction is not correct. In view of the inlet pressure situation, adjust the direction of thrust bearing. (5) bearing the port congestion, lead to bearing the casing heat can't discharge, temperature rise of the device. Deal with the outlet to clean up.

(6) has the following 4 reasons: (1) motor axis parallel to the asymmetry of pump shaft or not. The motor shaft and pump shaft should be adjusted, if shaft bending deformation or replace the shaft directly. (2) bearing assembly is not reasonable. The bearing and axle load, or replace the bearing. (3) pump with friction or impeller out of balance. Should eliminate friction or replace a new impeller. (4) the lubrication is not good. Too much too little impurity will result in bearing life is short, should remove bearing clean after use.
