Extending liquid slurry pump under transient method

how to extend household liquid slurry pump used under full

the supply of the following several ways to progress under the liquid slurry pump self-priming ability, extend its using life:

1, liquid slurry pump intake pipe cuts corners, drop height and horizontal distance.

2, liquid slurry pump in the pump suction pipe under the road set vacuum pump, the pump before the launch, vacuum pump, first make the pump suction tube is full of water, first ensure the pump automatically, sensitive.

3, liquid slurry pump suction pipe under the device suction foot valve at the end. Suction bottom valve is actually a check valve, it ensure that water can only be by the pool in suction pipe and cannot put back the clock, although the pump axis of water level elevation above the pool of homework, but due to have the effect of the suction bottom valve, the suction tube of water will not flow into the pool, can make the suction tube always be full of water.

4, this method has some trouble, but also is useful: liquid pump slurry pump set below before absorbing water tank.

pump shaft and motor shaft is not concentric can cause bearing temperature is too high, there are perhaps users to buy their own motor device in the process of the device itself is not good, only need to revise the pump shaft and motor shaft concentricity can. Bearing damage, may owe good quality also will affect the use, if found bearing wear more serious demand timely replacement.

under the corrosive liquid slurry pump discharge pressure faults cleaning methods

1, perhaps with reason

import pipeline gasket seal owe good, a flat. Partial blockage, packing leakage, impeller mouth ring wear may wear, impeller, pump shell inlet pressure was not enough.

2, solution

check import pipeline, replace, gaskets, adjust the packing gland, replace the packing may be mechanical seal, recoil pump cavity, clean the objects in the impeller, check parts, whether admit that mouth ring space within the scope of the rules, check the import line, to prevent clogging, open the valve.

under the liquid slurry pump assembly methods:

pump into the liquid pipe diameter shall not be greater than the rules require, in meet the requirements of the situation, the shorter the better. Into the liquid at the bottom of the tube is necessary gear mesh, particles or sundries are to prevent excessive after entering the pump body damage or affect the operation of the pump impeller, filter area should be greater than 3 - pipeline cross-sectional area 4 times. of the fluid control necessary is equipped with the valve in the road, traffic, to adjust the pump under the rules of traffic assignment, prevent excessive water pump can not work, after the liquid slurry water pump under liquid pipe diameter shall not be less than rules requirements, in the case of perhaps a liquid pipe diameter is bigger, the better.
