Description

Technical Field

[0001] This utility model relates to the field of self-priming pump technology, specifically to a leak-free vertical self-priming pump. Background Technology

[0002] The leak-free vertical self-priming pump is a pioneering product that fills a gap in the domestic market. It is widely used in industries such as petroleum, chemical, metallurgy, power, steel, mining, papermaking, electroplating, environmental protection, fire protection, construction, and sewage treatment. It partially replaces submersible pumps, long-shaft pumps, submersible sewage pumps, or pumps used in situations where they are frequently started. It is used to transport clean water, seawater, sewage containing small particles (excluding fibrous materials), industrial wastewater, oil, or various corrosive media.

[0003] For example, utility model CN208184995U discloses a leak-free vertical self-priming pump, including a pump body. The top of the pump body is connected to a support base via a support rod. The top of the support base is connected to a motor via a fixing rod. The output end of the motor is connected to one end of a rotating shaft, and the other end of the rotating shaft passes through the support base and the top of the pump body in sequence. This utility model has a simple structure. When bearing lubrication is required, rotating the screw causes the two connecting blocks to move closer together due to the opposite threads at the connection between the screw and the two connecting blocks. This causes the squeezing block to move closer to the cam, and the cam rotates. Through the combination structure of the squeezing block, connecting rod, connecting block, screw, and slider, and under the action of the second spring, the piston rod of the air cylinder moves back and forth, inflating the oil cylinder. Under the action of air pressure, the piston slides, squeezing the lubricating oil on one side of the piston and spraying it out from the oil guide pipe to lubricate the bearing and improve its service life. When lubrication is not required, simply rotate the screw in the opposite direction, which is extremely convenient.

[0004] In the process of developing this application, the following problems were found in the technology: when the air cylinder is reciprocated, the adjusting components (connecting block, screw, connecting rod) may loosen when the air cylinder inflates the oil cylinder, resulting in poor extrusion effect on the air cylinder and potentially insufficient amount of lubricating oil added to the bearing.

[0005] To address these shortcomings, a leak-free vertical self-priming pump was proposed, and the existing equipment was upgraded and modified. Utility Model Content

[0006] The purpose of this utility model is to provide a leak-free vertical self-priming pump in order to solve the problems in the background technology.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A leak-free vertical self-priming pump includes a pump body. A support frame is fixedly installed at the upper end of the pump body. A bearing is fixedly installed on the inner wall of the support frame. A rotating shaft is fixedly installed on the inner side of the bearing. A gear one is fixedly installed at the outer end of the rotating shaft. A gear two is meshed with the outer end of the gear one. The middle of the gear two is rotatably connected to the inner wall of the support frame. A sliding block is slidably connected to the inner wall of the gear two. A transmission block is provided at the outer end of the sliding block. A sliding plate is slidably connected to the outer end of the transmission block. A transmission rod is slidably connected to the inner wall of the sliding plate. A pressing plate is fixedly installed at one end of the transmission rod. An air cylinder abuts against the outer end of the pressing plate. The outer end of the air cylinder is fixedly installed to the inner wall of the support frame. An air pipe is fixedly installed at the outer end of the air cylinder. A hydraulic cylinder is fixedly installed at one end of the air pipe. A piston is slidably connected to the inner wall of the hydraulic cylinder. A connecting pipe is fixedly installed at the outer end of the hydraulic cylinder. One end of the connecting pipe abuts against the outer end of the bearing. An adjustment mechanism is provided at the outer end of the gear two.

[0009] Furthermore, a rotating plate is fixedly installed on the outer end of the support frame, and a one-way feed port is fixedly installed on one side of the upper end of the support frame. One end of the one-way feed port is fixedly installed on one side of the outer end of the oil cylinder.

[0010] Furthermore, a support plate is fixedly installed on the inner wall of the support frame, and the inner wall of the support plate is slidably connected to the outer end of the transmission rod.

[0011] Furthermore, the adjusting mechanism includes a pull block, the inner wall of the sliding plate is slidably connected to the pull block, the lower end of the pull block and the transmission block is rotatably connected to a slide rod, one end of the slide rod is fixedly installed with a rack plate, and the inner wall of the gear and the outer end of the transmission are provided with tooth grooves for the outer end of the rack plate to engage.

[0012] Furthermore, a stop block is fixedly installed at the outer end of the slide rod, and a spring is fixedly installed at the outer end of the stop block. One end of the spring is fixedly installed to the inner wall of the slide block or slide plate.

[0013] Furthermore, an inlet pipe is fixedly installed at one end of the pump body, and an outlet pipe is fixedly installed at the other end of the pump body.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention uses a rotating shaft to drive a first gear to rotate, which in turn drives a second gear to move a sliding plate at the outer end of the transmission block back and forth. This causes the transmission rod to compress the air cylinder, inflate the oil cylinder, and spray lubricating oil from the connecting pipe onto the side of the compression piston to lubricate the bearing and improve its service life.

[0016] This invention uses an upward pull on the transmission block and the pull block to move the slide rod, separating the rack plate from the tooth groove. This facilitates adjustment of the position of the slide block on the second gear and the position of the slide plate on the transmission rod, making it easier to avoid (or reduce) the pressure on the air cylinder and reduce the output of lubricating oil. The rack plate is connected to the tooth groove by the action of the spring, which facilitates fixation and improves stability. Attached Figure Description

[0026] like Figures 1 to 4 As shown, the leak-free vertical self-priming pump includes a pump body 1. A support frame 12 is fixedly installed on the upper end of the pump body 1. A bearing 16 is fixedly installed on the inner wall of the support frame 12. A rotating shaft 10 is fixedly installed on the inner side of the bearing 16. A gear 23 is fixedly installed on the outer end of the rotating shaft 10. A gear 22 is meshed with the outer end of the gear 23. The middle of the gear 22 is rotatably connected to the inner wall of the support frame 12. A sliding block 28 is slidably connected to the inner wall of the gear 22. A transmission block 21 is provided on the outer end of the sliding block 28. A sliding plate 29 is slidably connected to the outer end of the transmission block 21. A transmission rod is slidably connected to the inner wall of the sliding plate 29. 20. A compression plate 19 is fixedly installed at one end of the transmission rod 20. An air cylinder 18 is abutted at the outer end of the compression plate 19. The outer end of the air cylinder 18 is fixedly installed on the inner wall of the support frame 12. An air pipe 25 is fixedly installed at the outer end of the air cylinder 18. A hydraulic cylinder 27 is fixedly installed at one end of the air pipe 25. A piston 26 is slidably connected to the inner wall of the hydraulic cylinder 27. A connecting pipe 24 is fixedly installed at the outer end of the hydraulic cylinder 27. One end of the connecting pipe 24 abuts against the outer end of the bearing 16. An adjustment mechanism 3 is provided at the outer end of the gear 22. A water inlet pipe 14 is fixedly installed at one end of the pump body 1. A water outlet pipe 15 is fixedly installed at one end of the pump body 1.

[0027] Specifically, the rotating shaft 10 drives the gear 23 to rotate, which in turn drives the sliding plate 29 at the outer end of the transmission block 21 to move back and forth. This causes the transmission rod 20 to compress the air cylinder 18, inflate the oil cylinder 27, and spray lubricating oil from the connecting pipe 24 onto the side of the compression piston 26 to lubricate the bearing 16 and improve its service life.

[0028] like Figure 1 and Figure 2As shown, a rotating plate 13 is fixedly installed on the outer end of the support frame 12, and a one-way feed port 11 is fixedly installed on one side of the upper end of the support frame 12. One end of the one-way feed port 11 is fixedly installed on one side of the outer end of the oil cylinder 27; specifically, this facilitates the addition of lubricating oil to the oil cylinder 27.

[0029] like Figure 1 and Figure 2 As shown, a support plate 17 is fixedly installed on the inner wall of the support frame 12, and the inner wall of the support plate 17 is slidably connected to the outer end of the transmission rod 20; specifically, this facilitates the stable movement of the transmission rod 20.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the adjusting mechanism 3 includes a pull block 31, which is slidably connected to the inner wall of the sliding plate 29. The lower ends of the pull block 31 and the transmission block 21 are rotatably connected to a slide rod 34. A rack plate 36 is fixedly installed at one end of the slide rod 34. The inner wall 22 of the gear and the outer end of the transmission 20 are provided with a tooth groove 32 for the outer end of the rack plate 36 to engage. Specifically, by pulling the transmission block 21 and the pull block 31 upward, the slide rod 34 is moved, so that the rack plate 36 is separated from the tooth groove 32, which facilitates the adjustment of the position of the sliding block 28 on the gear 22 and the position of the sliding plate 29 on the transmission rod 20, so as to avoid (or reduce) the pressure on the air cylinder 18 and reduce the output of lubricating oil.

[0031] like Figure 3 and Figure 4 As shown, a stop block 35 is fixedly installed on the outer end of the slide bar 34, and a spring 33 is fixedly installed on the outer end of the stop block 35. One end of the spring 33 is fixedly installed on the inner wall of the slide block 28 or the slide plate 29. Specifically, the rack plate 36 is connected to the tooth groove 32 by the action of the spring 33.

[0032] In summary: When lubrication is required inside the device, the rotating shaft 10 drives the gear 23 to rotate, which in turn drives the sliding plate 29 at the outer end of the transmission block 21 to move back and forth. This causes the transmission rod 20 to compress the air cylinder 18, inflate the oil cylinder 27, and spray the lubricating oil from the connecting pipe 24 onto the side of the compression piston 26 to lubricate the bearing 16.

[0033] When the lubricating oil output needs to be adjusted, the transmission block 21 and the pull block 31 are pulled upward to move the slide rod 34, so that the rack plate 36 and the tooth groove 32 are separated, making it easier to adjust the position of the sliding block 28 on the gear 22 and the position of the sliding plate 29 on the transmission rod 20, so as to avoid (or lower) the pressure on the air cylinder 18 and reduce the output of lubricating oil. The rack plate 36 and the tooth groove 32 are connected by the action of the spring 33.
