Abstract

An amphibious motor for mining comprises a motor body and an air-water pressure self-balancing sealing device, wherein the air-water pressure self-balancing sealing device comprises a dynamic sealingdevice, an oil-air pressure self-balancer and an oil-water pressure self-balancer; the dynamic sealing device is installed at an output end of a power rotating shaft of the motor body and is connectedwith the front end cover of the motor body; the oil-air pressure self-balancer and the oil-water pressure self-balancer are mounted on the outer shell of the motor body through a bracket, and are connected with the dynamic sealing device. The invention is applicable to the use of power equipments such as power motors and pumps in damp mine environment, realizes amphibious operation of land and water, especially improves the ability of resisting water inrush disaster of the mine, or rapidly recovers drainage capacity after flooding, and realizes rapid recovery of production.

Description

technical field [0001] The invention relates to the technical field of mining power equipment, in particular to a mining amphibious motor. Background technique [0002] As the depth and difficulty of mine mining continue to increase, mine water inrush and flood accidents occur frequently. At present, the power equipment such as motors, water pumps, fans, and hydraulic stations in the main drainage system of mines have only realized the popularization and application of underground explosion-proof technology. , neither moisture-proof, nor waterproof, nor can it be operated in deep water. The motor is damp and causes insulation reduction, which often causes failures and shutdowns. At present, coal mine safety regulations stipulate that large-scale submersible pumps must be installed in large water mines to prevent flooding disasters, and regular water test operation or maintenance should be carried out. Due to the low reliability of submersible pumps, frequent start-up failur...
