Description

Technical Field

[0001] The utility model relates to the technical field of motor structures, in particular to special equipment for spraying powder coating primer on petroleum pipelines. Background Art

[0002] During the production of oil pipelines, a powder coat primer is applied to the inner wall to enhance the pipeline's corrosion resistance and extend its service life. During this process, a paint spray motor is used. The primary function of a paint spray motor is to provide power to drive the spray equipment. Using either electric or pneumatic means, the paint is dispersed into a mist and sprayed onto the surface. Specifically, the paint spray motor operates by controlling the airflow to momentarily reverse the direction of the air distribution reversing mechanism, thereby causing the pneumatic motor's piston to perform a steady and continuous reciprocating motion. The piston is rigidly connected to the plunger in the paint pump. The larger area of ​​the piston increases the pressure of the drawn paint. The pressurized paint is then transported via a high-pressure hose to the spray gun, where it is instantly atomized and released onto the surface, forming a coating film.

[0003] Existing paint spray motors need to run for a long time when spraying primer on a large area. A large amount of heat is generated during the operation of the motor. Currently, a fan is mostly installed to dissipate heat from the motor, but the heat dissipation effect is poor and easily affects the service life of the motor. Utility Model Content

When the paint spraying motor body 1 drives the output shaft 11 to rotate during operation, it can drive the No. 1 pulley 24 to rotate, and the No. 2 pulley 253 is driven to rotate through the transmission of the belt body 254, thereby prompting the rotating shaft 252 to rotate on the side of the liquid driving cylinder 251, providing power for the circulation of the coolant, avoiding the problem of high cost caused by relying on the drive device to provide power.

[0021] As an implementation method in this embodiment, Figure 1-Figure 4As shown, the left side of the liquid driving cylinder 251 is rotatably connected to the rotating shaft 252, and the left end of the rotating shaft 252 is fixedly connected to the second pulley 253. The outer walls of the second pulley 253 and the first pulley 24 are detachably connected to the belt body 254. The inner wall of the liquid driving cylinder 251 is rotatably connected to the impeller 2511. The right end of the rotating shaft 252 extends into the inner cavity of the liquid driving cylinder 251 and is fixedly connected to the left side of the impeller 2511. When the impeller 2511 rotates in the inner cavity of the liquid driving cylinder 251, it can push the coolant in the inner cavity of the liquid driving cylinder 251 to the left, causing the coolant to circulate through the curved pipe 1 263, the strip pipe 1 26, the arc-shaped copper pipe 262, the strip pipe 261, the curved pipe 3 283, the hollow plate 281, the curved pipe 282 and the inner cavity of the liquid driving cylinder 251.

Through the design of the reinforcement seat 27, the paint spraying motor body 1 can be firmly supported with the help of the right side plate seat 23. The cold end of the semiconductor refrigeration plate 284 is attached to the outer surface of the hollow plate 281. The operation of the semiconductor refrigeration plate 284 can be controlled to cool the circulating coolant. The low-temperature coolant will circulate through the inner cavity of the arc-shaped copper tube 262, and will be subjected to heat exchange and cooling treatment on the outer surface of the paint spraying motor body 1. Through the design of the partition 2811 and the through hole 2812, the uniformity of the flow of the coolant in the hollow plate 281 is improved, and the cooling effect of the coolant is increased.
