Mining type flameproof submersible motor

Abstract

The invention discloses a mining type flameproof submersible motor, comprising a left end cover and a right end cover; a tube-shaped engine base is hermetically fixedly connected between the left and right end covers, the engine base is internally provided with a stator core, the stator core is internally provided with a rotor, and the output shaft of the rotor stretches out the left end cover; one end of the engine base is hermetically connected with a cable outlet device, the cable of the stator core is led out by the cable outlet device; the upper part of the engine base is provided with a forced cooling fan, the air outlet of the forced cooling fan is provided with a duct, and the outlet of the duct is arranged corresponding to the right end cover. The invention has compact structure, the tube-shaped engine base is hermetically fixedly connected with the left and right end covers, and the tube-shaped engine base is hermetically connected with the cable outlet device, so that the mining type flameproof submersible motor has good sealing property and is applicable to underwater use. The invention has less vibration when in operation and good heat dissipation effect, the existing permeable disaster relief device is not required to be used when the invention is adopted, and cost is greatly saved.

Description

technical field [0001] The invention relates to a mining motor. Background technique [0002] Existing common motors have no waterproof function and cannot be used underwater. The motors used in existing submersible pumps are all wet submersible motors. Compared with ordinary motors (non-wet motors), this kind of motor has extremely low operating efficiency. It is in line with the environmental protection policy of energy saving and consumption reduction that the country is currently vigorously promoting, and cannot be used as a motor for the normal drainage system of coal mines. The above situation makes it necessary for a mine to be equipped with an additional set of mine permeable disaster relief equipment. Currently, the commonly used permeable disaster relief equipment is expensive (about 20 million yuan), and the later repair and maintenance costs are relatively high. In order to reduce the investment cost of coal mines and improve the operation economy of drainage e...
