Because of its special function, high-pressure metering pump is often used under high pressure conditions, but also some intermittent work, continuous work, no matter what kind of conditions will cause some damage to high-pressure metering pump. In order to find out the problems of high-pressure metering pump or avoid adverse events, maintenance of high-pressure metering pump is carried out, from the maintenance of four aspects of high-pressure metering pump.
1. After each use of the high-pressure metering pump, flush the remaining liquid in the hose and nozzle with clean water, clean the chassis, put the power cord together, and then store it in a fixed place. Damage or insufficient pressure was found. Maintenance should be marked and used only after timely notification.
2. Maintenance personnel are responsible for the maintenance of high-pressure metering pump, check the operation of high-pressure metering pump every day, and make good records. If damaged leather bowl is found, aging will lead to air leakage, pressure will not disappear, should be replaced in time.
3. Electrical performance, mechanical performance, main engine and main contactor switch of high-pressure metering pump motor shall be checked every half month, and necessary lubricant shall be added to ensure the normal use of the equipment and record well.
4. High-pressure metering pump should maintain a certain oil level. Generally speaking, the oil-immersed surface should be kept between 6/10 and 7/10. If oil shortage is found, it should be replenished in time to ensure the normal operation of the unit.
