Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mud pumps, in particular to a built-in heat dissipation device for a mud pump. Background Art
[0002] At present, in the coal mining industry, mud pumps are often used in conjunction with underground horizontal directional drilling rigs. Due to the limited space underground, the mud pump is required to be as small as possible. In order to reduce the volume, the mud pump is generally designed with a high pump speed of 400-700 strokes per minute. The heat problem caused by high-speed operation is more obvious, so corresponding heat dissipation devices are needed.
[0003] Figure 1 As shown, this is a commonly used high-speed mud pump body and its heat dissipation structure. Its working principle is: the crankshaft (108) rotates at high speed, and the connecting rod (110) converts the rotational motion into the linear reciprocating motion of the crosshead (113) and the pull rod (114). There is high-speed friction heat generation between the connecting rod big end bearing (9) and the crankshaft (108), between the connecting rod small end bearing (112) and the crosshead pin (111), and between the crosshead (113) and the mud pump body (107), thereby increasing the oil temperature. In order to reduce the oil temperature, in addition to natural heat dissipation through the mud pump body (107) and the rear cover (106), there is generally a forced heat dissipation device. The gear pump (104) sucks out the oil through the oil pipe B (105), and then discharges the oil into the radiator (101) through the oil pipe A (102). After cooling, the oil flows back to the mud pump body (107) through the oil outlet pipe (103). The cooler dissipates heat through circulating water. The disadvantage of this structure is that it takes up a certain amount of space and increases the volume, and also increases the cost because a separate radiator and gear pump need to be added. Summary of the invention
[0004] The present application provides a built-in heat dissipation device for a mud pump, thereby solving the problem that the heat dissipation device of the existing mud pump not only occupies a certain space and increases the volume, but also increases the cost.
[0005] In order to achieve the above-mentioned purpose, this application adopts the following technical solution.
[0006] Provided is a built-in heat dissipation device for a mud pump, comprising a pump body and a rear cover plate installed at the end of the pump body; the rear cover plate protrudes outward from the pump body; a heat conduction plate is provided between the rear cover plate and the pump body, so that a first cavity is formed between the heat conduction plate and the pump body, and a second cavity is formed between the heat conduction plate and the rear cover plate, and the second cavity is provided with a water inlet and a water outlet connected thereto.
[0007] The present application has at least the following technical effects or advantages: compared with the prior art, the present invention not only simplifies the structure and layout of the heat dissipation device and reduces the volume of the whole machine, but also eliminates the need to purchase external radiators and gear pumps, thereby reducing production costs.

[0012] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0013] See also Figure 2 A built-in heat dissipation device for a mud pump includes a pump body 203 and a rear cover plate 201 installed at the end of the pump body 203. The rear cover plate 201 protrudes outward from the pump body 203. A heat conducting plate 202 is provided between the rear cover plate 201 and the pump body 203, so that a first cavity 204 is formed between the heat conducting plate 202 and the pump body 203, and a second cavity 205 is formed between the heat conducting plate 202 and the rear cover plate 201. The second cavity 205 is provided with a water inlet 206 and a water outlet 207 connected thereto.
[0014] When in use, the oil temperature in the first cavity 204 transfers heat to the second cavity 205 formed between the heat conducting plate 202 and the rear cover plate 201 through the heat conducting plate 202, and water enters the second cavity 205 from the water inlet 206 and flows out of the second cavity 205 from the water outlet 207, thereby taking away the heat in the second cavity 205 and realizing the heat dissipation of the mud pump.
