Description

Technical Field

[0001] The utility model relates to the field of pump cooling devices, in particular to an automatic water cooling device for a vacuum pump. Background Art

[0002] When the temperature of the vacuum pump is too high, the pump will trip, which may be caused by the following reasons: 1. Too much gas in the pump. When too much gas accumulates in the vacuum pump, the gas pressure and temperature will rise sharply, causing the pump temperature to be too high, thus causing the pump to trip.

[0003] 2. Abnormal working conditions. Some abnormal working conditions can also cause the vacuum pump temperature to be too high, such as overload or cycle overheating.

[0004] 3. There are foreign objects inside the pump body. If too much pump oil or other objects enter the pump body, it will cause abnormal heat accumulation and cause the pump temperature to be too high.

[0005] An automatic water cooling device can be provided on the surface of the pump body to reduce the temperature of the vacuum pump during operation.

[0006] The existing automatic water cooling device for vacuum pumps is not easy to achieve uniform cooling effect on the surface of the vacuum pump body, which may lead to reduced cooling efficiency of the device. The existing automatic water cooling device for vacuum pumps is not easy to conveniently disassemble and assemble the device, which may lead to reduced efficiency during inspection and maintenance of the device.

[0007] Therefore, in view of the above problems, an automatic water cooling device for a vacuum pump is proposed. Utility Model Content

[0026] Furthermore, the shape of the top surface of the support plate 2 matches the shape of the surface of the vacuum pump body 41, and the inner wall of the support frame 3 is slidably connected to the surface of the vacuum pump body 41;

[0027] During operation, the inner wall of the support frame 3 and the surface of the vacuum pump body 41 are designed to be slidably connected, and the vacuum pump body 41 and the cooling pipe 12 are disassembled to facilitate the inspection and maintenance of the interior of the device.

[0028] Furthermore, the inner wall of the liquid storage tank 6 is provided with two through holes 10, and the inner sides of the two through holes 10 are fixedly connected with cooling pipes 12;

[0029] During operation, the inner sides of the two through holes 10 on the inner wall of the liquid storage tank 6 are fixedly connected with cooling pipes 12, so that the coolant circulates through the through holes 10 and the cooling pipes 12, thereby improving the cooling effect of the device.

[0030] Furthermore, the cooling pipe 12 is zigzag in shape, the inner wall of the cooling pipe 12 is closely attached to the surface of the vacuum pump body 41 , and the cooling pipes 12 are evenly distributed on the surface of the vacuum pump body 41 .

[0031] During operation, the zigzag cooling pipes 12 are evenly distributed on the surface of the vacuum pump body 41 through the structural design, and the inner wall of the cooling pipe 12 is tightly fitted to the surface of the vacuum pump body 41, so that the cooling pipe 12 has a uniform cooling effect on the surface of the vacuum pump body 41, thereby improving the cooling efficiency of the device.

[0032] Furthermore, a shell 5 is mounted on the surface of the support plate 2, and a storage box 13 is fixedly connected to the inner wall of the shell 5;

[0033] During operation, the outer shell 5 is installed by snap-fitting the surface of the support plate 2, thereby improving the sealing between the outer shell 5 and the vacuum pump body 41. The inner wall of the outer shell 5 is fixedly connected with the storage box 13, and quicklime is placed in the storage box 13 to absorb moisture from the air inside the outer shell 5, thereby reducing the amount of moisture adhering to the surface of the cooling pipe 12 when the device is cooled, thereby protecting the cooling pipe 12 and increasing the service life of the device.

[0036] Working principle: When the motor 4 drives the vacuum pump body 41 to work, a large amount of heat is generated inside the vacuum pump body 41 due to the friction between the parts. The vacuum pump body 41 is slidably installed on the surface of the support plate 2 and the support frame 3 in advance. At this time, the surface of the vacuum pump body 41 fits the surface of the cooling pipe 12. A proper amount of coolant is added through the water inlet pipe 8. The sealing cover 9 is installed on the top of the water inlet pipe 8. The water pump 11 is started by an external power supply. The water pump 11 draws coolant from the through hole 10 and pours it into the cooling pipe 12. Since the zigzag cooling pipes 12 are evenly distributed on the surface of the vacuum pump body 41, the inner wall of the cooling pipe 12 fits tightly to the vacuum pump body 41. The surface of the empty pump body 41 makes the cooling pipe 12 have a uniform cooling effect on the surface of the vacuum pump body 41. The outer shell 5 is clamped above the support plate 2, and the storage box 13 is fixedly connected to the inner wall of the outer shell 5. Quicklime is placed in the storage box 13 to absorb the moisture of the air inside the outer shell 5, thereby reducing the moisture attached to the surface of the cooling pipe 12 when the device is cooled, protecting the cooling pipe 12, and improving the service life of the device. The inner wall of the support frame 3 is slidably connected to the surface of the vacuum pump body 41, which facilitates the disassembly of the vacuum pump body 41 and the cooling pipe 12, and facilitates the inspection and maintenance of the inside of the device.
