Description

Technical Field

[0001] The utility model relates to the technical field of water ring vacuum pumps, in particular to a self-adaptive gas volume regulating structure of a water ring vacuum pump. Background Art

[0002] The water ring vacuum pump is a positive displacement pump. The pump body is filled with an appropriate amount of liquid (usually water) as the working medium. When the eccentrically installed impeller rotates, the liquid is thrown around due to the centrifugal force, forming a closed circular ring similar to the shape of the pump chamber. At this time, a closed cavity is formed between the impeller hub and the liquid ring, and the gas enters the closed cavity on the suction side at a certain flow rate through the suction port of the distribution plate.

[0003] According to an automatic air volume regulating device for a vacuum pump mentioned in Chinese utility model 202222864882.9, the automatic air volume regulating device for a vacuum pump solves the current problem that the air volume of the vacuum pump is adjusted by replacing the piston and the connecting rod, and the disassembly is complicated and affects the work efficiency of the staff. However, the process of adjusting the air volume of the automatic air volume regulating device for the vacuum pump is relatively complicated when in use, and the correlation effect cannot be achieved if a single part is damaged. Therefore, it is necessary to propose an adaptive air volume regulating structure for a water ring vacuum pump to solve the above-mentioned problems. Utility Model Content

[0006] The gas volume regulating mechanism includes a first support bearing, the first support bearing is fixedly installed inside the fixed plate, the second support bearing is fixedly installed inside the pump pipe, connecting rods are movably installed inside the first and second support bearings, a connecting tube is fixedly connected to one end of the connecting rod, and a limited rotation plate is fixedly connected to one side of the connecting tube.

[0008] Furthermore, a limiting through hole is provided inside the limiting rotating plate, the positioning rod passes through the limiting through hole, and the positioning rod is slidably installed inside the limiting through hole.

[0009] Furthermore, the rotating structure includes a driving motor, and the driving motor is fixedly installed on the top of the fixed plate. A gear is fixedly connected to the output shaft of the driving motor, and gear rings are meshed with each other on the outer surfaces of the gears.

[0010] Furthermore, the gear ring is fixedly mounted on the outside of the swivel.

[0011] Furthermore, an air volume regulating plate is fixedly mounted on the outer surface of the connecting rod, a micro balance wheel is fixedly mounted on the inner wall of the rotating ring, and the micro balance wheel is slidably mounted on the outer surface of the pump tube.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The adaptive gas volume regulating structure of the water ring vacuum pump is provided with a gas volume regulating mechanism. When in use, by starting the driving motor, the output shaft of the driving motor will drive the gear to mesh with the gear ring, so as to drive the swivel to rotate outside the pump pipe. When the swivel rotates, the positioning rod will be driven to rotate horizontally. Since the positioning rod passes through the limiting through hole, the limiting rotating plate is further driven by the positioning rod to change its angle. When the limiting rotating plate rotates, the connecting tube will be driven to rotate. When the connecting tube rotates, the connecting rod will be driven to rotate inside the first support bearing and the second support bearing.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The gas volume regulating mechanism 6 includes a first support bearing 601, the first support bearing 601 is fixedly installed inside the fixed plate 4, the second support bearing 603 is fixedly installed inside the pump pipe 1, a connecting rod 602 is movably installed inside the first support bearing 601 and the second support bearing 603, a connecting tube 604 is fixedly connected to one end of the connecting rod 602, and a limited rotation plate 606 is fixedly connected to one side of the connecting tube 604.

[0021] In specific implementation, by setting the gas volume regulating mechanism 6, when in use, by starting the driving motor 301, the output shaft of the driving motor 301 will drive the gear 302 to engage with the gear ring 303, so as to drive the swivel 2 to rotate outside the pump tube 1. When the swivel 2 rotates, it will drive the positioning rod 605 to rotate horizontally, and because the positioning rod 605 passes through the limiting through hole 608, the limiting rotating plate 606 is further driven by the positioning rod 605 to change the angle. When the limiting rotating plate 606 rotates, it will drive the connecting tube 604 to rotate. When the connecting tube 604 rotates, it will drive the connecting rod 602 to rotate inside the first support bearing 601 and the second support bearing 603. When the connecting rod 602 rotates, it will drive the gas volume regulating plate 5 to adjust the angle, so as to achieve the effect of gas communication between the pump tube 1 and the outside world. The larger the rotation angle of the gas volume regulating plate 5, the more gas passes through the pump tube 1, which greatly shortens the gas volume regulation steps and the operation steps are simple.

[0022] When implementing, follow these steps:

[0023] 1) First, through the action of the rotating structure 3;

[0024] 2) Then, by starting the driving motor 301, the output shaft of the driving motor 301 drives the gear 302 to mesh with the gear ring 303, thereby driving the rotating ring 2 to rotate outside the pump pipe 1;

[0025] 3) When the rotating ring 2 rotates, the positioning rod 605 will be driven to rotate horizontally, and the positioning rod 605 passes through the limiting through hole 608;

[0026] 4) Finally, the positioning rod 605 is used to further drive the limit rotating plate 606 to change its angle. When the limit rotating plate 606 rotates, it will drive the connecting tube 604 to rotate. When the connecting tube 604 rotates, it will drive the connecting rod 602 to rotate inside the first support bearing 601 and the second support bearing 603. When the connecting rod 602 rotates, it will drive the gas volume adjustment plate 5 to adjust its angle, thereby achieving the effect of gas communication between the pump tube 1 and the outside world.

[0027] In summary, the adaptive gas volume regulating structure of the water ring vacuum pump is provided with a gas volume regulating mechanism 6. When in use, by starting the driving motor 301, the output shaft of the driving motor 301 will drive the gear 302 to mesh with the gear ring 303, so as to drive the swivel 2 to rotate outside the pump pipe 1. When the swivel 2 rotates, it will drive the positioning rod 605 to rotate horizontally. Moreover, since the positioning rod 605 passes through the limiting through hole 608, the limiting rotating plate 606 is further driven by the positioning rod 605 to change the angle. When the limiting rotating plate 606 rotates, it will drive the connecting tube 604 to rotate. When the connecting tube 604 rotates, it will drive the connecting rod 602 to rotate inside the first support bearing 601 and the second support bearing 603. When the connecting rod 602 rotates, it will drive the gas volume regulating plate 5 to adjust the angle, so as to achieve the effect of gas communication between the pump pipe 1 and the outside. The larger the rotation angle of the gas volume regulating plate 5, the more gas passes through the pump pipe 1, which greatly shortens the steps of gas volume regulation and has simple operation steps.
