High-pressure-bearing and high-load-bearing vertical pipeline pump

Abstract

The utility model discloses a high-pressure-bearing and high-load-bearing vertical pipeline pump which comprises a pump body. The impeller end of the pump body is sleeved with two shells, and the shells are of a symmetrical structure and jointly form a complete protection shell structure. A water injection port is formed in the top of one shell and is used for injecting water into the protective shell formed by the two shells; a plurality of heat exchange pipes which are uniformly distributed up and down are arranged on the sides, far away from each other, of the shells; one end of the heat exchange pipe is communicated with an air inlet pipe which is longitudinally arranged; therefore, cold air in the heat exchange pipe can exchange heat with the heat-conducting medium in the shell, the heat-conducting medium can continuously absorb heat in an impeller cavity of the pipeline pump due to the fact that the temperature of the heat-conducting medium is reduced, and it is guaranteed that the pipeline pump cannot be overheated when conveying a high-temperature medium. Therefore, the high pressure-bearing and high-bearing performance of the pipeline pump is reduced, and the service life of the pipeline pump is prolonged.

[0028] Please refer again to Figure 4 As shown in the figure, one of the housings 2 is provided with a water inlet 14 at the top, the water inlet 14 is used for injecting water into the protective shell formed by the two housings 2; a heating pipe 5 is arranged in the protective shell formed by the two housings 2, and the heating pipe 5 is used for increasing the temperature of the water body; a temperature sensor 10 is further arranged in the protective shell formed by the two housings 2, and the temperature sensor 10 is used for detecting the temperature of the water body in the protective shell formed by the two housings 2.

[0029] Please refer again to Figure 4 and Figure 5 As shown in the figure, a plurality of heat exchange pipes 7 are arranged on the sides of the housings 2 away from each other and are uniformly arranged upward and downward, the heat exchange pipes 7 are in U-shaped structure, the corners of the heat exchange pipes 7 are arranged on the inner side of the housings 2, and the straight pipes are arranged on the outer side of the housings 2; one end of the heat exchange pipe 7 is communicated with an air inlet pipe 6, and the air inlet pipe 6 is arranged longitudinally.

[0030] Please refer again to Figure 5 As shown in the figure, the upper end of the air inlet pipe 6 is fixedly connected with a fixed plate 11; the fixed plate 11 is provided with a fan 12; a filter screen 13 is arranged on the air inlet side of the fan 12, the filter screen 13 is used for preventing mosquitoes and dust from entering the inside of the heat exchange pipe 7; the fan 12 and the filter screen 13 are fixedly connected with the fixed plate 11 through bolts.

[0031] In order to facilitate the understanding of the above technical scheme of the utility model, the working principle or operation mode of the utility model in the actual process is described in detail as follows:

[0032] The working personnel first fixes the two housings 2 at the impeller end of the pump body 1 through the cooperation of the screw 9 and the bolt, accommodates the pump cavity inside the protective shell formed by the two housings 2, and completes the sealing between the two housings 2 by the flange 3 and the sealing gasket 8 to ensure that the air tightness is sufficient; then, clean water or other heat-conducting liquids such as oil liquid are added from the water inlet 14 to the inside of the protective shell formed by the two housings 2; after that, if the heat of the medium delivered by the pump body 1 is high, the fan 12 is started to deliver cold air or air from the air inlet pipe 6 to the inside of the heat exchange pipe 7, and since the heat exchange pipe 7 is partially located inside the housing 2, the cold air in the inside of the heat exchange pipe 7 can exchange heat with the heat-conducting medium in the inside of the housing 2, at this time, since the temperature of the heat-conducting medium is lowered, the heat-conducting medium will continuously absorb the heat in the inside of the pump impeller cavity, so that the pipeline pump will not overheat when delivering high-temperature medium, the high-pressure and high-load performance of the pipeline pump is reduced, and the service life of the pipeline pump is improved.

[0033] It is worth noting here that: in addition to reducing the heat in the inside of the heat exchange pipe 7 by the fan 12, the inside of the air inlet pipe 6 can also exchange heat with the cooling liquid, and the cooling effect is better; the straight pipe of the heat exchange pipe 7 is located outside the housing 2, which can exchange heat with the outside air in cold weather, and improve the cooling effect of the pipeline pump when delivering high-temperature medium.

[0034] If the heat of the medium delivered by the pipeline pump body 1 is low, and the pipeline pump is located in an area with low temperature, the impeller in the inside of the pump body 1 will freeze in the stopped running state due to the low temperature, the pipeline pump will become brittle, it is difficult to rotate when starting, and it is easy to be damaged when being knocked from the outside, so the use of the housing 2 not only plays a role in protecting the impact, but also cooperates with the heating pipe 5 to heat the liquid in the inside of the protective shell formed by the two housings 2, and thaw the inside of the pipeline pump body 1 through heat exchange, so as to ensure the normal operation of the pipeline pump, improve the service life of the pipeline pump, and improve the load and pressure bearing capacity.
