Five solutions to sand dredge pump problems
With the continuous development of technology, it has brought great convenience to people. In the coastal water-filling project, the use of sand pumping pump and the traditional mountain-loading soil-removing construction use the sand pump to fill the land, the advantage is to avoid The use of mountains to extract soil brings environmental damage, but also improves work efficiency. At the same time, the pump is also used in chemical, mining, electric power, building materials and other industries. China Do Pump is a dredge pump solution provider, for how to select a sand dredge pump, due to the different working environment, dredge pump can be selected as submersible dredge pump, on board sand pump, ladder pump, booster pump, in many working conditions, ladder submerged dredge pump are working with on board sand pump and booster pump, therefore China Do Pump would like to share with the knowledge of five solutions to sand dredge pump problems
Five solutions to sand dredge pump problems
1. The pump does not turn when starting.
Cause: The packing is too tight or the impeller and the pump body are stuck by the debris; the pump shaft, the bearing, and the leakage ring are rusted; the pump shaft is severely bent.
Remedy: Relax the packing, dredge the large pump for draining the pump: remove the pump to remove debris or rust; correct the bent shaft or replace the pump shaft.
2. After the start, the sand pump does not produce water.
Cause: There is air or inlet pipe in the pump; the bottom of the impurity pump is not tightly filled, the vacuum pump is seriously leaking; the gate valve or the door is not closed.
Remedy: remove debris, replace the damaged rubber mat, large sand pump to change the direction of the valve; press or replace the new filler, close the gate valve or flap the door; increase the amount of irrigation until the vent plug does not take Bubble; replace the cracked tube water; reduce the lift, press the nozzle of the pump into the water 0.5 m.
3, the pump flow is insufficient
Reason: The actual lift of the pump exceeds the allowable head; the speed is not matched or the belt is slipping, the speed is low; the installation angle of the axial pump blade is too small; the suction stroke is too high; the bottom valve, pipeline and impeller are partially blocked or the impeller is missing; the outlet pipe is leaking serious.
Remedy: reduce the lift, restore the rated speed, remove the belt dirt and adjust the belt tightness; adjust the blade angle to reduce the pump installation position; tighten the gland, seal the water pump leakage, press the packing or replace the packing; remove the blockage, Replace the impeller with a sand pump; replace the leak ring and block the leak.
4, the flow of the pump from large to small
Cause: The filter or bell mouth is gradually blocked by debris; the water level of the impurity pump is lowered, and the water depth of the inlet pipe is insufficient. Remedy: Remove debris and increase the depth of the bottom valve.
5. The water discharge during the operation of the pump is not interrupted by water or intermittently, and the water is less. 1 The motor does not start, the circuit is faulty; 2 the pipeline is blocked, the blockage is removed; 3 the pipeline is broken, repaired or replaced; 4 the filter screen is blocked, the blockage is removed; 5 the water outlet is exposed to the water surface, if the discharge pump is still When it is invalid, it is recommended to change the pump; 6 electric pump reverses, replaces the phase sequence of the power line; 7 pump casing seal ring, impeller damage, replace new parts.
