The common problems and solutions of high lift slurry pump

High lift slurry pump will often encounter many problems in the application, if not timely and effective treatment, the conveying effect may influence the pump, this paper mainly aims at the high lift slurry often appear in the application of the problem and how to solve the topic do related analysis, the hope can help the concentrator to better improve the efficiency of transporting pump, to increase economic benefit.

Slurry pump is a kind of high lift, high lift mine conveying equipment, compared to the traditional pump efficiency is more significant, can transport the lift has been increased greatly, is widely used in the field of mining, metallurgy, coal, electric power and other industries. High lift slurry pump common problems at work mainly includes: the head is insufficient, bearing, motor overheating running overload, no water, slurry pump.

The common problems and solutions of high lift slurry pump

1, issue: lift less than. High lift slurry pump because the pump cavitation may be inadequate or insufficient, the motor speed impeller wear caused serious.

1, solution: such as the lower pump installation position, or increase the height of the liquid at the inlet of the pump, and timely replacement of severe wear of the impeller, motor selection.

2, issue: bearing overheating. High lift bearing in slurry pump if it exceeds the transmission capacity of the pump will affect the normal temperature range, a common cause of overheating of bearing are: deterioration of lubricant, the bearing box is lack of oil, pump shaft is not concentric with the motor shaft, and the pump shaft deformation.

2, common solutions such as: timely replacement add oil and lubricating oil, check the rolling bearing runout, generally not more than 0.05MM.

3 issues: the operation of the motor overload. There are many, the cause of high lift slurry pump motor running overload include: large flow pump, pump running shaft deformation, mutual friction between rotating parts.

3, common solutions such as: timely check the correction of pump shaft, the proper use of control operation parameters, discharge the mutual friction problem between the pump body.

4 problem: no water slurry pump. Water slurry pump is due to the high lift impeller flow channel blockage, lift device beyond the scope of design and running direction lift impeller error causes.

Solution: 4, general as long as the time to clean up the debris blocked impeller, correct the motor power wire connection or select the appropriate pump can not solve the problem of water pump and effective.

The correct use and inspection of high lift of slurry pump maintenance is very important, is the premise to ensure the basic working pump work in normal operation; in addition, in the purchase of slurry pump should be targeted to buy. At present, An Pump Machinery is a professional production and sale of high lift rubber slurry pump professional manufacturers, high lift wear rubber slurry pump production and two-stage wear-resistant slurry pump used An Pump wear resistant rubber, energy saving, stable operation, high lift, large flow quantity, low cost, high work efficiency compared with other slurry pump, easy maintenance and management, is the choice of the material conveying highly corrosive best, by the vast number of domestic and foreign customers trust and recognition.
