Abstract

The invention provides a submersible electric pump. The submersible electric pump comprises a submersible pump body and a submersible motor. The submersible pump body and the submersible motor are connected together. The submersible electric pump further comprises an explosion-proof cover. The explosion-proof cover is of a cover structure with an opening part and is connected to the submersible motor through the opening part, so that the main part of the submersible motor is located in the cover structure. According to the technical scheme, the explosion-proof cover is arranged on the main part of the submersible motor in a covering mode; on the condition that combustible gas exists in the place where the submersible electric pump exists, even if short circuit, sparking and other faults occur in an inner cavity of the submersible motor, the faults can be enclosed in the explosion-proof cover, combustion gas in the ambient environment cannot be ignited, and therefore the safety of the submersible electric pump is improved.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a submersible electric pump. Background technique [0002] Submersible pumps are mainly used in petroleum, chemical, coal mine and other industries. For example, submersible pumps can be used to pump liquids containing flammable gases in the medium, or to pump liquids with flammable gases in the workplace. [0003] With the rapid development of my country's industrialization process, petroleum, chemical, natural gas, petrochemical, coal mine, pharmaceutical and other industries need a large number of submersible pumps with explosion-proof or explosion-proof functions. However, ordinary submersible pumps do not have explosion-proof or explosion-proof functions, and faults such as motor ignition and short circuit may cause the explosion of surrounding flammable gases, so there are potential safety hazards. Therefore, it is necessary to improve the above-mentioned defects existing in the...
