Problems solved by technology

However, the existing motor cooler is directly installed at the end of the motor cavity to form an integral structure, which leads to the fact that the submersible motor can only be used in water. If it is placed on land, the cooler cannot touch the water, and the motor cannot be to cool down
Moreover, the integrated cooler will increase the length of the motor, which requires a wider diameter slot when it is placed in the mine cavern.

Embodiment Construction

[0025] For ease of understanding, combined here Figure 1-2 , the concrete structure and working mode of the present invention are further described as follows:

[0026] The specific structure of the present invention is as Figure 1-2 As shown, it mainly includes a motor cavity 40, the motor is placed inside the motor cavity 40, the motor cavity 40 is provided with a cavity, and the cavity is located outside the motor rotor cavity. The cavity is filled with coolant, and when the rotor of the motor heats up, the heat is transferred to the coolant in the cavity for heat exchange, thereby cooling the motor.

[0027] It also includes a cooler 10, the cooler 10 is a hollow structure, and a cooling cavity 11 is provided inside it, and the cooling cavity 11 communicates with the motor cavity 40, and the cooling fluid after heat exchange flows into the cooling cavity 11 along the hot water pipe 30 for cooling .

[0028] The cooling chamber 11 surrounds the inner pipe 12 to increas...

Abstract

The invention belongs to the field of mine construction, and particularly relates to a land-submersible dual-purpose motor which comprises a motor cavity used for containing a motor and provided with an internal pipeline. The motor cavity is provided with a cavity used for being filled with cooling liquid, and the cavity is arranged outside a motor rotor cavity, so that heat exchange between the cooling liquid and the rotor cavity can be facilitated. The motor further comprises a heat exchange part arranged in water, the heat exchange part comprises a cooling cavity arranged at the outer side of the internal pipeline, and the cooling cavity is communicated with the cavity of the motor cavity through a pipeline so as to facilitate the circulation of cooling liquid. The internal pipeline is communicated with an external water body so as to facilitate the water absorption and heat exchange, and the internal pipeline and the motor cavity are arranged in a split mode and is connected through a pipeline, so that the motor can be used in water and also can be used on land; and when the motor is used on land, only a cooler needs to be placed in water to absorb water flow, and the split type structure enables the length of the motor to be shortened, thereby being more flexible.

Description

technical field [0001] The invention belongs to the field of mine construction, and in particular relates to a land-submarine dual-purpose motor. Background technique [0002] The main drainage pumps in mines are mostly traditional MD multistage centrifugal pumps, and the motors used are mostly traditional air-cooled motors, which are afraid of water ingress. However, in recent years, the development of water-filled submersible motors has provided an additional option for mine safety, which can It is very good at responding to sudden and extreme situations, and provides assistance for disaster relief and mine recovery rescue. [0003] Due to the characteristics of submersible motors that require diving, the sealing performance must be particularly perfect, which makes it difficult to solve the problem of heat dissipation, so a cooler must be used to take away the heat of the motor in a water-cooled manner. However, the existing motor cooler is directly installed at the end ...
