AI Technical Summary
Technical Problem
Existing oil-immersed submersible pumps are prone to clogging after impurities enter, affecting water intake efficiency and energy consumption. Furthermore, their heat dissipation is limited, leading to increased energy consumption.
Method used
Design an oil-immersed energy-saving multi-stage submersible pump. The pump uses a ring array of heat dissipation baffles distributed on the outside of the inlet filter cartridge for heat exchange and impurity blocking to prevent filter pore blockage. It is combined with insulating lubricating oil for heat dissipation and lubrication.
Benefits of technology
It improves heat dissipation and water intake efficiency, reduces the probability of clogging, lowers energy consumption and costs, and enhances energy-saving performance.

Abstract
The utility model discloses an oil-immersed energy-saving multistage submersible pump which comprises a submersible motor, a multistage impeller and a water inlet filter cylinder, the water inlet filter cylinder is arranged above the submersible motor, the multistage impeller is arranged above the water inlet filter cylinder, a first cover plate is arranged at the top of the submersible motor, and a second cover plate is arranged at the bottom of the submersible motor. A first flange connected with the first cover plate is arranged at the bottom of the water inlet filter cartridge, and heat dissipation stop levers vertically extending to the outer side of the water inlet filter cartridge are arranged on the first cover plate at intervals. According to the oil-immersed type energy-saving multi-stage submersible pump, the heat dissipation stop levers are distributed on the outer side of the water inlet filter cylinder, the oil-immersed type energy-saving multi-stage submersible pump can make contact with flowing water flow to conduct heat exchange, the heat dissipation effect is improved, impurities can be blocked, large impurities are prevented from entering gaps between the heat dissipation stop levers and the water inlet filter cylinder, and therefore the probability that filter holes are blocked is reduced, and the service life of the submersible pump is prolonged. The water inlet efficiency is improved, and the energy consumption and cost are reduced.
