Fault prone to slurry pump in operation

Fault prone to slurry pump in operation

In the production of sometimes slurry pump without sizing phenomenon, the main reasons are:

(1) the slurry processing is not good and the production management, the slurry mixing with wood chips, rope, yarn and other debris, causing slurry pump port plug. Encounter this kind of situation, must stop cleaning. In order to prevent this phenomenon, we must strengthen the management of slurry concentration and clean production workshop.

(2) slurry pump flange or the stuffing sealing lax, into the air, or slurry fiber adsorption amounts of air, resulting in slurry pump conveying capacity and head down, when the need to tighten the flange and the packing gland. As for the adsorption of a large number of air bubbles in the pool of slurry, water washed or adding defoaming agent, to remove the slurry in the air.

(3) slurry pond bottom slurry concentration is too high, grout resistance, hinder the slurry pump export into pulp, then, need to add water dilute the pool size.

(4) into the slurry pipeline with small diameter, elbow, long distance, plus elbow angular misalignment, resulting in pulp resistance, concentration is high will slurry pump without sizing. Solution: in addition to control the slurry concentration, should use the overhaul time to transform into the slurry pipeline.

(5) slurry pump slurry inlet pipeline valve opening is small, slurry flow is small, the filtered water is good in the long fiber pulp thickening, caused by slurry agglomerate and interrupt pulp. The solution is: to open a large valve, increase the amount of slurry through.

(6) slurry pond slurry level is too low, the slurry entrained air into the slurry pump.

(7) the new installation of the slurry pump or slurry pump motor maintenance, motor wiring errors caused by slurry pump, slurry pump reverse operation, no starch. The correction circuit wiring.
