Slurry Pump Maintenance and repair
Note the editor
Mud pump before starting, please check the inlet pipe, outlet pipe is blocked, whether the front and rear bearing butter, check the packing is full. Mud pump work should be equipped with high pressure water pump, will be greater than the pressure of the mud pump water leakage leak-proof filler, the filler protection, mud pump work should not close the washing pump, otherwise, will make the seal part of the rapid wear and tear. Whether the gap between the impeller and the guard plate is reasonable, a great impact on the life of the mud pump. The gap is unreasonable, the pump running vibration and noise, the flow components will soon be damaged, so replace the impeller, should pay attention to the gap to meet the requirements of the drawings, gap adjustment, through the rear bearing body on the adjustment screw to carry out. The allowable suction of the mud pump is measured when the water is delivered, and the effect of the mud on the suction capacity should be taken into account when sucking the slurry.
Maintenance and repair
The construction department should have specialized maintenance personnel, responsible for the construction machinery maintenance and repair. Regular mud pump and other machinery to check, maintain, early problems to be resolved, so as to avoid downtime. Construction should pay attention to the size of sediment particles, particles will often check the muddy parts of the mud pump in order to timely repair or replacement. Mud mud damage parts are mainly pump shell, bearings, impeller and so on. The use of advanced anti-wear measures to improve the service life of vulnerable parts, can reduce the input of the project to improve production efficiency. At the same time should be prepared vulnerable parts, in case of timely replacement.
Construction, machinery, mud pump continuous normal work in order to make the mud pump to play the highest efficiency. Therefore, there must be a reasonable schedule, strict management system.
Edit the operation procedure
1, before the start of inspection: the connection parts to be fastened; electric rotation direction should be correct; clutch flexible and reliable; pipe connection is firm, reliable sealing, flexible and effective bottom valve.
2, before the start of the mud pump before the suction pipe, the end of the valve, the pump must be filled with water, pressure gauge buffer filled with oil at the top.
3, by hand rotation, so that the piston back and forth twice, no obstruction and the line insulation is good when no load start, start, to be normal operation and then gradually increase the load.
4, the operation should pay attention to the sealing device sealing situation, if necessary, to be adjusted. The rod and the auxiliary rod should always be lubricated with oil.
5, the operation is often tested mud sediment concentration shall not exceed 10%.
6, there are several speed of the mud pump to make the splash lubrication and reliable, should be in the operation of each class will be a few files speed were running, the time is not less than 30 seconds.
7, is strictly prohibited in the operation of the variable speed, the need to shift the pump should stop gear shift.
