Video course of oil pump refueling

The water pump refueling tutorial is as follows:

1. If it is a single feed pump, you can directly open the breathing hole of the bearing seat to refuel.

2. If it is a feed water pump set in the form of coupler, directly add it to the coupler oil tank. If it is a feed water pump driven by a steam turbine, directly add it to the oil tank of a small steam turbine.

3. Ensure that the submersible pump is closed, disconnect the power supply, and wait for the pump body to cool before refueling. 2. Find the oil filler plug or dipstick on the pump body and remove the oil filler plug.

4. Inject a proper amount of special lubricating oil for submersible pump, not too full, which shall be subject to the scale line of dipstick. 4. Replace the oil filler plug and tighten it.

5. Open the submersible pump to fully lubricate the lubricating oil in the pump body and make it work more smoothly. It should be noted that the lubricating oil of oil-immersed submersible pump needs to be replaced regularly to ensure its stable performance and long service life.

Expand knowledge-pump explanation;

Generally speaking, it is recommended to change the lubricating oil once a year, and the specific time interval should be determined according to the frequency of use and working conditions. Before filling the submersible pump, it is necessary to check whether there are impurities and dirt in the pump body, and if necessary, it needs to be cleaned and maintained to ensure the clean and normal operation of the pump body.

A water pump is a machine that transports or pressurizes liquid. It transfers the mechanical energy or other external energy of the prime mover to the liquid, which increases the energy of the liquid. It is mainly used for conveying liquids, including water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, as well as liquids, gas mixtures and liquids containing suspended solids.

The technical parameters of pump performance include flow, suction, lift, shaft power, hydraulic power and efficiency. According to different working principles, it can be divided into positive displacement pump and vane pump. The displacement pump uses the change of its working chamber volume to transfer energy; Vane pumps use the interaction between rotating blades and water to transfer energy, including centrifugal pumps, axial pumps and mixed-flow pumps.
