Oil immersion type water proof diving pump

Abstract

The present invention relates to an oil-immersed waterproof submerged pump. A rotor and a stator coil wound with waterproof wires are arranged in the housing cavity of a submerged motor; insulating oil is used as the cooling medium of the housing cavity; a rear bearing and a bearing cover are mounted on the rear end of a motor shaft; a lead-out wire tube, which can lead out a lead-out wire, is mounted on a base; a housing, the base and a front cover close the housing cavity; a front bearing and a mechanical seal, which are fastened in the central hole of the front cover, are mounted in the middle part of the motor shaft; water fills up a sealing chamber; a submerged pump vane wheel is mounted on the front end of the motor shaft; a pump seat is mounted on the front end of the sealing chamber; a pump cover is mounted on the front end of the pump seat; the pump cover is provided with a water inlet; a filtering net is mounted on the front end of the pump cover; a water outlet is arranged on a submerged pump body. The oil-immersed waterproof submerged pump has the advantages that: the temperature raise of the motor is reduced, and the power of the motor is increased; the service life of the motor is increased; the service life of a bearing is prolonged; water source is prevented from being polluted; the oil-immersed waterproof submerged pump can be used in dirty water.

Description

technical field [0001] The invention relates to an oil-immersed waterproof submersible pump. Background technique [0002] At present, the insulating oil in the sealing chamber of the oil-immersed small submersible pump submersible motor commonly used is easy to leak, resulting in short service life and water pollution; If it is not good, it will cause bearing damage and the insulating oil in the sealed chamber of the dry submersible pump will easily leak, resulting in water pollution, poor heat dissipation, and easy coil burnout. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide an oil-immersed waterproof submersible pump with long service life and no water source pollution. [0004] The technical solution of the present invention is: an oil-immersed waterproof submersible pump, which is characterized in that: the inner cavity of the submersible motor has a rotor and a stator coil of waterproof wire ...
