[0002] A mud pump is a device used to transport mud or suspended particle liquid. It is widely used in oil drilling, underground engineering, mining, construction engineering and other fields for mud circulation, cleaning, transportation and pressurization. A mud pump is usually composed of a pump body, a motor, a delivery pipeline and a control system. Its working principle is to generate pressure through mechanical equipment such as pistons, gears, and impellers inside the pump body to suck mud or suspended particle liquid into the pump body, and then transport it to the required location through pipelines. Mud pumps are corrosion-resistant, efficient and stable, and can adapt to complex working conditions. Depending on specific engineering requirements and operating scenarios, the types and specifications of mud pumps will vary.

In order to reduce mud erosion, a protective casing is often set outside the mud pump. In order to ensure the heat dissipation effect, the existing mud pump protective casing has poor sealing, poor protection effect, and better sealing but poor heat dissipation performance.
