The construction department should have specialized maintenance personnel, responsible for the construction machinery maintenance and repair. On a regular basis mud pump and other mechanical inspection, maintenance, problems to be resolved as soon as possible in order to avoid downtime. Construction should pay attention to the size of sediment particles, that must often test the muddy parts of the mud pump in order to timely repair or replacement. Mud pump is easy to damage the components of the pump shell, bearings, impellers 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.
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, liquid mud pump before starting, suction pipe, bottom valve, the pump body must be filled with water, pressure gauge top of the buffer filled with oil.
3, hand rotation, so that the piston back and forth twice, no obstruction and the line insulation is good when the no-load start, after starting, 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 often test mud sediment content 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, don`t change speed when the mud pump in the operation ,otherwise you need to shift the pump.
