How to maintain a multi-stage pump

Multi-stage pumps, which are horizontal centrifugal multi-stage pumps, adopt the hydraulic model of high-efficiency and energy-saving products recommended by the country and occupy a leading position in the industry. D-type horizontal centrifugal multi-stage pump has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long life, easy installation and maintenance.

Applicable to factories, mines, cities, power plants, petroleum, chemical, light work, environmental protection, water supply and drainage, farmland drainage and irrigation and various water conservancy projects. Multi-stage pumps are relatively common and the material is generally cast iron. Therefore, it can be seen that the application of D-type horizontal centrifugal multi-stage pump is more extensive, and more occasions are used, so we need to have a good maintenance and maintenance of D-type horizontal centrifugal multi-stage pump in order to make horizontal centrifugal Multi-stage pumps operate safely and steadily with long service life.

1. Maintenance:

a. Multi-stage pump deactivation period. Replace the old horizontal centrifugal multistage pump packing; Replace the horizontal centrifugal multi-stage pump oil (pump at the pump thrust bearing); Rinse the horizontal centrifugal multistage pump guide bearing in water every month for about 2 minutes; while turning the pump rotor Check the hydrodynamic horizontal multi-stage pump water-skiing system and check if the fasteners are loose.

b. Leakage of multistage pump packing when multi-stage pump is running; Lubrication pressure of multi-stage pump; Lubricating oil level and bearing temperature of multi-stage pump; Good operation log, such as horizontal centrifugal multi-stage pump failure recording.

2. Overhaul:

a. When overhauling the multi-stage pump, the motor control switch must be in the “off” position and hang the warning plate to avoid personal injury.

b. When the multi-stage pump is disassembled, marks shall be made at the fittings of the various parts so that the installation can be carried out smoothly; the small parts and fasteners removed from the multi-stage pump are packed in boxes, marked well, and the place is marked The parts removed by the multi-stage pump are cleaned, coated with anti-rust oil, if there is rust on the painted surface, the corrosion shall be removed and repainted; the horizontal multi-stage centrifugal pump “O” ring, packing, and rust Fasteners cannot be reused and spare parts are ready.
