It is mainly used in: hydraulic presses, high-pressure cleaning, high-pressure rust removal, hydraulic cleaning, mine water supply, boiler water supply, light industry and food, chemical industry, oil field water injection, oil transportation and other departments that need to transport high-pressure liquids.

[0003] The pump needs to run efficiently for a long time. At the same time, the motor temperature must not exceed 90°C, the lubricating oil temperature must not exceed 70°C, and the temperature of the plunger and seal friction pair must not exceed 75°C. In order to ensure the stability of the pump during operation, the slurry pump needs to be cooled and its temperature controlled.

[0004] The existing cooling method is to weld heat sinks on the surface of the motor and install water-cooling pipes for heat dissipation. However, under harsh working conditions, the joints of the water-cooling pipes are prone to lose their seals after being exposed to the sun, resulting in leakage of the coolant, while water droplets, oil stains, dust, etc. are not allowed to enter the inside of the motor. It is also necessary to regularly check and clean the motor terminals, check whether the wiring screws of the junction box are loose, and perform a series of maintenance work. Therefore, the water-cooling pipes installed on the surface of the motor need to be removed during each maintenance, resulting in cumbersome maintenance. Utility Model Content

[0008] A second switch door is arranged on the side of the shell, a blower is penetrated through the second switch door, and through holes are opened on both sides of the shell.

[0009] Preferably, universal wheels are provided at four corners of the bottom of the shell, a first switch door is provided at the top of the shell, and heat insulation panels are provided on the surfaces of the shell, the first switch door and the second switch door.
