Description

Technical Field

[0001] The invention relates to the technical field of vacuum pumps, and in particular to a multi-stage direct-connected water ring vacuum water pump. Background Art

[0002] Multi-stage water ring vacuum pump is a commonly used vacuum equipment. Through the rotation and centrifugal action of the water ring and a continuous multi-stage exhaust process, the gas is drawn into the pump, thereby achieving a high vacuum extraction effect. It has a simple structure, is easy to operate, has low maintenance costs, and has high exhaust efficiency, which can effectively improve work efficiency.

[0003] However, the multi-stage water ring vacuum pump also has some shortcomings. Due to the friction and impact of the water ring, the pump noise is relatively large; the water ring is subject to wear and corrosion and needs to be replaced and maintained regularly. Therefore, the multi-stage water ring vacuum pump needs noise reduction and regular maintenance, which means that the vacuum pump is required to have the characteristics of low noise and easy disassembly and assembly.

[0004] To solve the above problems, we proposed a multi-stage direct-connected water ring vacuum pump. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose a multi-stage direct-connected water ring vacuum water pump.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a multi-stage direct-connected water ring vacuum water pump, including a vibration-damping pump body and a pump seat, the vibration-damping pump body includes a vacuum pump, the lower side wall of the vacuum pump is fixedly provided with a support seat, the lower side wall of the support seat is symmetrically fixed with two unconnected pads, the lower side of the pad is provided with a mounting plate, the lower side wall of the pad is symmetrically provided with two rubber pads, the rubber pads are fixedly connected to the upper side wall of the mounting plate, the left and right ends of the mounting plate extend outwardly from the corresponding pads, the middle part of the lower side wall of the support seat is fixedly provided with a spring 1 located between the two pads, and the spring 1 is fixedly connected to the mounting plate.

[0007] The cam is connected with a support plate at the upper end thereof to form a rotation between the two support plates, the upper end of which is connected with a spring, and the two support plates are connected with a spring.

[0008] In the above-mentioned multi-stage direct-connected water ring vacuum water pump, the limiting mechanism includes a socket fixedly connected to the upper side of the rotating seat, the socket is provided with a socket 1 that penetrates the front and rear side walls thereof, the front side wall of the rotating block is provided with a socket 2 corresponding to the socket 1, and an insertion rod is slidably inserted in the sockets 1 and 2, the front end of the insertion rod extends out of the outside of the socket, the front end of the insertion rod is fixedly connected with a pull handle, the insertion rod is provided with a spring 3, and the two ends of the spring 3 are respectively fixedly connected to the pull handle and the front side wall of the socket.

[0009] In the above-mentioned multi-stage direct-connected water ring vacuum water pump, a rubber pad is fixedly provided in the middle of the upper side wall of the transverse plate.

[0010] In the above-mentioned multi-stage direct-connected water ring vacuum water pump, vertically upward baffles are fixedly provided on the front and rear edges of the upper side wall of the transverse plate, and the clamping block is located between the two baffles.

[0011] In the above-mentioned multi-stage direct-connected water ring vacuum water pump, the clamping blocks are arranged in a strip shape, and the opposite side walls of the two clamping blocks are arranged inclined.

[0012] In the above-mentioned multi-stage direct-connected water ring vacuum water pump, a plurality of positioning holes are provided on the positioning plate.

[0013] Compared with the existing technology, the advantages of this multi-stage direct-connected water ring vacuum water pump are:

[0014] 1. The pump body of the present invention has a vibration reduction characteristic, thereby achieving noise reduction when the vacuum pump is working. The pad and the mounting plate are fixedly connected by a plurality of rubber pads. The rubber pads are close to the outer edge of the mounting plate. The rubber pads are elastic and can reduce the intensity of vibration transmitted to the mounting plate, and have a certain buffering effect. At the same time, the spring located in the middle of the lower wall of the support seat can also reduce the intensity of vibration, further buffer the vibration of the vacuum pump, and achieve noise reduction.

[0015] 2. The pump seat is fixed in the working environment of the vacuum pump through the positioning plate. The pump seat is symmetrically provided with blocks. When the mounting plate is pressed down horizontally, the blocks are squeezed by the mounting plate and slide to both sides until the mounting plate goes down over the blocks. At this time, under the elastic action of the second spring, the blocks return to the original position to limit the mounting plate. The rubber pad on the horizontal plate is elastic and exerts squeezing force on the mounting plate to make the mounting plate fit with the blocks. When disassembling the pump body and the pump seat, only the handle needs to be pulled outward to release the limit of the rotating block by the plug rod and make the rotating block deflect to both sides. At this time, the blocks will deflect immediately and the mounting plate can be directly taken out. The design of this pump seat is conducive to the rapid disassembly and assembly of the vibration-damping pump body and the pump seat, and is convenient for regular maintenance of the vacuum pump.

[0016] In summary, the present invention achieves noise reduction by arranging a spring and multiple rubber pads between the support seat and the mounting plate to weaken the vibration intensity generated by the operation of the vacuum pump. At the same time, the mounting plate and the pump seat are limited by a clamping block. The limiting mechanism can release the limitation of the insert rod on the rotating block, and the clamping block can be deflected, which is beneficial to the rapid disassembly and assembly of the vibration-damping pump body and the pump seat.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 6 A multi-stage direct-connected water ring vacuum water pump comprises a vibration-damping pump body and a pump seat. The vibration-damping pump body comprises a vacuum pump 1. A support seat 2 is fixedly arranged on the lower side wall of the vacuum pump 1. Two unconnected pads 3 are symmetrically fixed to the lower side wall of the support seat 2. The pads 3 are respectively located at the left and right ends of the support seat 2. A mounting plate 4 is arranged on the lower side of the pad 3. The mounting plate 4 is arranged in a rectangular shape, and the front and rear side walls of the mounting plate 4 are aligned with the front and rear side walls of the pad 3. Two rubber pads 5 are symmetrically arranged on the lower side wall of the pad 3. The rubber pads 5 are fixedly connected to the upper side wall of the mounting plate 4. The left and right ends of the mounting plate 4 extend outwardly from the corresponding pads 3. A rubber pad 5 located at two ends is fixedly arranged in the middle of the lower side wall of the support seat 2. A spring 6 is provided between the pads 3, and the spring 6 is fixedly connected to the mounting plate 4. The vibration generated by the vacuum pump 1 when working is transmitted to the mounting plate 4 through the support seat 2 and the pad 3. The spring 6 uses its own elastic characteristics to buffer the vibration force transmitted from the support seat 2 to the mounting plate 4, reduce the intensity of the vibration, and weaken the vibration force transmitted to the mounting plate 4. At the same time, in addition to supporting the pad 3, the rubber pad 5 is also elastic and can buffer the vibration force transmitted from the pad 3 to the mounting plate 4, and weaken the intensity of the vibration. Under the joint action of the spring 6 and multiple rubber pads 5, the vibration transmitted from the vacuum pump 1 to the mounting plate 4 is buffered, thereby achieving a noise reduction function.

[0026] In order to improve the connection strength between the rubber pad 5 and the pad 3 and the mounting plate 4, two threaded tubes are fixedly embedded in the rubber pad 5, and the two threaded tubes face the pad 3 and the mounting plate 4 respectively. The pad 3 and the mounting plate 4 are fastened to the two threaded tubes by screws respectively to improve the connection strength between the rubber pad 5 and the pad 3 and the mounting plate 4.

[0027] The pump seat includes a transverse plate 7, which is arranged in a rectangular shape. The left and right ends of the transverse plate 7 are fixedly connected to support plates 8 arranged vertically downward. The lower ends of the support plates 8 are fixedly connected to positioning plates 9. The positioning plates 9 are provided with a plurality of positioning holes 21. The positioning plates 9 can be fixed in the working environment of the vacuum pump 1 through the positioning holes 21, so that the pump seat is fixed. When disassembling and assembling the shock-absorbing pump body, the pump seat is kept fixed, and the shock-absorbing pump body is installed on the pump seat or removed from the pump seat.

[0028] The two positioning plates 9 are symmetrically arranged horizontally outward, and two rotating seats 10 are symmetrically fixed on the outer wall of the support plate 8. The two rotating seats 10 are respectively located at the front and rear ends of the support plate 8. A rotating block 11 is connected to the two rotating seats 10 for common rotation. The rotating block 11 is arranged vertically upward, and the inner side wall of the rotating block 11 is in contact with the outer side wall of the corresponding support plate 8. The support plate 8 limits the rotating block 11. The rotating block 11 is symmetrically arranged with guide holes running through its left and right side walls front and back. The two guide holes are distributed near the front and rear ends of the rotating block 11. Guide columns 12 are slidably inserted in the guide holes, and the ends of the two guide columns 12 are fixed together. A block 13 located on the inner side of the rotating block 11 is fixedly connected, and the block 13 is located on the upper side of the cross plate 7. The block 13 is arranged in a strip shape, and the relative side walls of the two blocks 13 are inclined. Specifically, the inclined wall of the right block 13 is arranged with the left lower and the right higher, and the inclined wall of the left block 13 is arranged with the right bottom and the left higher, that is, it is convenient for the mounting plate 4 to squeeze the block 13 downward from the upper side of the block 13 so that the block 13 slides outward. The inclined side walls are all smoothly arranged, and a spring 2 14 located between the block 13 and the rotating block 11 is sleeved on the guide column 12, and the two ends of the spring 2 14 are fixedly connected to the block 13 and the rotating block 11 respectively.

[0029] The two rotating seats 10 located at the front end of the support plate 8 are both provided with a limiting mechanism, which is used to adjust the position of the rotating block 11, that is, to control the rotating block 11 to be in a fixed state or an active state. The limiting mechanism includes a socket 15 fixedly connected to the upper side of the rotating seat 10, and the socket 15 is provided with a socket 1 that runs through its front and rear side walls, and the front side wall of the rotating block 11 is provided with a socket 2 corresponding to the socket 1, and a rod 16 is slidably inserted in the sockets 1 and 2, and the front end of the rod 16 extends out of the outside of the socket 15, and the front end of the rod 16 is fixedly connected to a handle 17, and the outer wall of the handle 17 is provided with an anti-slip texture to facilitate workers to operate. The pull handle 17 and the plug rod 16 are sleeved with a spring three 18, and the two ends of the spring three 18 are fixedly connected to the pull handle 17 and the front side wall of the socket 15 respectively. The spring three 18 generates a pulling force on the pull handle 17, so that the plug rod 16 squeezes the inner bottom wall of the socket two, so that the plug rod 16 is stabilized in the sockets one and two and remains stable. At this time, the rotating block 11 remains vertically set and is limited by the plug rod 16. When the pull handle 17 is pulled outward, the spring is stretched, the plug rod 16 moves out of the socket two, and the limit on the rotating block 11 is released, keeping the plug rod 16 in the socket one. At this time, the deflected rotating block 11, the guide column 12 will drive the card block 13 to deflect to both sides.

[0030] A rubber pad 19 is fixedly provided in the middle of the upper side wall of the transverse plate 7, and vertical baffles 20 are fixedly provided at the front and rear edges of the upper side wall of the transverse plate 7, and the clamping block 13 is located between the two baffles 20. The pump seat is first fixed in the working environment of the vacuum pump 1 through the positioning plate 9, and then the vibration reduction pump body is disassembled and assembled. The process of installing the vibration reduction pump body to the pump seat is as follows:

[0031] When the mounting plate 4 is moved downward over the block 13, the extrusion force exerted on the block 13 disappears, and the block 13 returns to its original position under the action of the spring 14, forming a limit for the mounting plate 4 on the lower side. After the mounting plate 4 exceeds the block 13 downward, it contacts the rubber pad 19, and the rubber pad 19 is elastic, which generates an upward pressure on the mounting plate 4, so that the mounting plate 4 fits the block 13. At the same time, the two baffles 20 on the cross plate 7 limit the front and rear side walls of the mounting plate 4, so that the mounting plate 4 is fixed on the pump seat.

[0032] The process of removing the vibration damping pump body from the pump seat is as follows:

[0033] Pull the two handles 17 on the front side respectively, pull the insertion rod 16 forward out of the second socket on the rotating block 11, and separate the insertion rod 16 from the rotating block 11. At this time, the rotating block 11 is deflected to the outside of the support plate 8. At this time, the guide column 12 will also drive the block 13 to deflect outward, and the block 13 is separated from the mounting plate 4. The limit of the mounting plate 4 is released. At this time, the vacuum pump 1 can be directly held by hand to take the vibration reduction pump body out of the pump seat.

[0034] When installing the vibration damping pump body again, deflect the rotating block 11 to be vertical, and then insert the insertion rod 16 into the second insertion hole on the rotating block 11 to fix the rotating block 11 vertically, and then repeat the above installation steps.

[0035] The present invention has the following characteristics:

[0036] 1. The pump body has vibration reduction characteristics. The pad 3 and the mounting plate 4 are fixedly connected by a plurality of rubber pads 5. The rubber pads 5 are elastic and can reduce the intensity of the vibration transmitted to the mounting plate 4, and have a certain buffering effect. At the same time, the spring 6 located in the middle of the lower wall of the support seat 2 can also reduce the intensity of the vibration, and further buffer the vibration of the vacuum pump 1, so as to achieve noise reduction when the vacuum pump 1 is working.

[0037] 2. The pump seat is fixedly arranged in the working environment of the vacuum pump 1 through the positioning plate 9. The blocks 13 are symmetrically arranged on the pump seat. When the mounting plate 4 is pressed down horizontally, the blocks 13 are squeezed by the mounting plate 4 and slide to both sides until the mounting plate 4 exceeds the blocks 13 downward. At this time, under the elastic action of the spring 2 14, the blocks 13 return to the original position to limit the mounting plate 4. The rubber pad 19 on the cross plate 7 is elastic and produces an extrusion force on the mounting plate 4, so that the mounting plate 4 fits with the blocks 13. When disassembling the pump body and the pump seat, it is only necessary to pull the handle 17 outward to release the limit of the rotating block 11 by the plug rod 16, so that the rotating block 11 deflects to both sides. At this time, the blocks 13 deflect immediately, and the mounting plate 4 can be directly taken out. The design of the pump seat is conducive to the rapid disassembly and assembly of the vibration-damping pump body and the pump seat, and is convenient for regular maintenance of the vacuum pump 1.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
