Slurry pump pipe road configuration considerations, pipe diameter size to consider system resistance, comprehensive factors such as the critical settling velocity of slurry. Suction tube short and straight as far as possible. The entrance in the pump suction, equipped with a best with imported straight pipe of the same diameter, the length shall be not less than three times the diameter of imports. Suction tube flow generally 1.5 3.0 m/s, depending on the conveyor slurry settling velocity.
Using high layout of the pump inlet line should avoid formation of slug, recommends the busbar for levels of variable diameter tube. Flow adjusting valve, regulating valve should be located in the pump discharge, are not allowed in regulating valve in the inlet pipe on the road, lest produce cavitation.
Slurry pump, the pump must be placed on land, suction pipe in the water, also need irrigation pump start-up. Mud pump and axillary slurry pump due to the limitation of the structure, work when the motor must be placed on the surface, pump into the water, so must be strong, otherwise, the motor falls into the water will lead to scrap. And because the long axis length is usually fixed, so the pump installation using more troublesome, is limited by a lot of application occasions.
Furthermore is to avoid frequent switch, do not frequently switch slurry pump, this is because the electric pump stalling generates a return, if immediately turned on the motor load startup, causing the start current is too large, burn winding due to the large startup current, frequent start will burn out submersible pump motor windings.
