How to maintain a progressive cavity pump

Screw pump structure is simple, not only stable and reliable when running, but also very durable, and has the advantage of low input costs, is currently one of the mainstream transport equipment, but in order to further extend its service life, know how to maintain the screw pump is still very necessary, in the pump industry to study the field of screw pumps for more than thirty years, has a mature and rich experience in pump making, the following for you to briefly introduce relevant maintenance knowledge.

For the screw pump how to maintain, mainly according to the frequency of use of equipment to carry out a series of routine checks, timely detection and correction of problems. It is recommended to arrange a person responsible for the use and maintenance of the screw pump, according to the following introduction to the pump body maintenance.

First, daily inspection and maintenance

Screw pumps are mostly used to deal with the complex composition of the media, inevitably over a long period of time on the internal structure of the pump body caused by wear and tear, the base and pump body fastening bolts may also occur loose, if not pay attention to inspection may lead to the displacement of the pump body, resulting in the consequences of pipeline rupture. Therefore, it is recommended that the equipment users spend a few minutes to observe the fastening bolts of the machine pump, gear box oil level and wear of the packing before starting the equipment every day to ensure that it is normal before starting the machine, and listen carefully to the normal running sound after starting the machine, if the internal mechanism is damaged it is likely to lead to strange noises.

Second, develop a regular maintenance plan

It is usually recommended that three months to six months for a more comprehensive inspection, the specific time according to the working environment and the frequency of use to decide, the first need to replace the gearbox oil, and clean the gearbox to ensure the lubricity of the screw pump. Pay extra attention to rolling bearings and gearbox lubrication, while ensuring that the rubber sheath of the coupling is intact without wear and tear, followed by a variety of vulnerable parts of the pump body aging and wear inspection, replace new parts as needed.

Third, a long time after the maintenance of the pump

For more than a week of pump downtime equipment, it is recommended to focus on lubricating oil or soapy water, and the use of tools to wrench a few turns to ensure adequate lubrication before connecting to the power supply, and remember to check the valves on the inlet and outlet pipelines to ensure that they can work properly, all aspects of the confirmation is correct before normal start.

Above, is the basic introduction of how to maintain the screw pump, I believe you also have a clearer understanding of this, if you are interested in knowing more details, you can continue to pay attention to Zhaoquan.
