Description

Technical Field

[0001] The invention relates to the technical field of pump body processing detection, in particular to a pump body air tightness detection device. Background Art

[0002] Sewage pumps are a type of centrifugal impurity pumps, and come in a variety of forms: submersible and dry. Most sewage pumps are mainly used to transport urban sewage, feces or liquids containing solid particles such as fibers and paper scraps. At the same time, some sewage pumps can also be used in industrial production to discharge high-temperature high-pressure sewage, so some sewage pumps are designed to withstand high temperatures of 80°C or even 100°C.

[0003] During the production process of submersible sewage pumps, the pump body needs to be tested for air tightness. Usually, an interface is installed on the vent screw hole of the pump body and the air pipe is inserted. At the same time, a closed interface or a pressure gauge is installed on the other end of the pump body, that is, the oil chamber cover oil filling hole. The pump body is then submerged in the water of the test pool for observation to see whether there are bubbles to determine whether the quality of the pump body is qualified. However, the water temperature is mostly room temperature, which cannot simulate a high temperature environment and cannot detect the air tightness of the pump body under a high temperature environment. Even if the water temperature is heated to 100°C, the water will boil and produce a large number of bubbles, affecting observation. The pump body will be stained with some dust during the processing process, or some pump bodies will be locally rusted due to being stored for too long, and there are also debris generated by the workshop itself. These impurities follow the pump body into the water in the pool. After testing multiple pump bodies, the pool water can easily become turbid under the influence of impurities, affecting the observation of bubbles. Therefore, the water needs to be replaced frequently, consuming a lot of water resources. Summary of the invention

At this time, the pump body is suspended and fixed above the pool body 4, and the hose 2511 is connected to the pump body. Then, the valve on the surface of the gas pipe 8 is opened to allow high-pressure gas to enter the shell 1. The air pressure sensor 27 will monitor the air pressure in the shell 1 and transmit it to the control panel 5, and display it on the control panel 5 until the air pressure inside the shell 1 is 200kPa, which is about two atmospheres, and the air supply to the inside of the shell 1 is stopped.

[0044] While supplying air to the inside of the shell 1, the drive motor 18 is turned on, and its output shaft drives the long rotating rod 15 to rotate through gears, and the long rotating rod 15 drives the spiral blades 16 on its surface to rotate. Since the height of the inner cylinder 14 is lower than the pool body 4, the water inside the pool body 4 enters the inner cylinder 14 through the connecting pipe 12 under the action of gravity. Under the action of the spiral blades 16, the water is continuously pushed to the end close to the delivery pipe 19. At the same time, the electric heating pipe 17 heats the water flowing inside the inner cylinder 14 to increase the water temperature. The heated water flows into the treatment pool 20 through the delivery pipe 19.

[0045] The scooping and filtering mechanism 21 includes a first transverse plate 211, a frame 217, and a second transverse plate 2112. The number of the first transverse plate 211 and the second transverse plate 2112 are both several. The first transverse plate 211 and the second transverse plate 2112 are both bolted to one side of the treatment tank 20. The surface of the first transverse plate 211 is rotatably connected to a rotating column 212. The surface of the rotating column 212 is fixed with a first gear 213. A connecting frame 216 is also welded to one side of the surface of the rotating column 212. The other end of the connecting frame 216 is bolted to the frame 217. A filter screen 218 is installed on the surface of the frame 217. A scooping net 219 is also installed on the surface of the frame 217. The shape of the inner wall of the treatment tank 20 is an inverted trapezoidal design, and the shape of the frame 217 is the same as the shape of the inner wall of the treatment tank 20. The first A torsion spring 215 is fixed to the surface of the horizontal plate 211, and a lever 214 is also fixed to the surface of the rotating column 212, and the lever 214 and the other end of the torsion spring 215 are in contact with each other. A connecting rod 2110 is rotatably connected to the surface of the second horizontal plate 2112, and a second gear 2111 used in conjunction with the first gear 213 is fixed to the surface of the connecting rod 2110. The tooth distribution angle of the second gear 2111 is 250-270°, that is, there is a gap without teeth on the surface of the second gear 2111. A support platform 29 is also bolted to the inside of the housing 1. The scooping and filtering mechanism 21 also includes a support plate 2113 bolted to one side of the support platform 29. The surface of the support plate 2113 is rotatably connected to a vertical transmission column 2114. The bottom end of the vertical transmission column 2114 is connected to the long rotating rod 15. The top of the vertical transmission column 2114 is connected to the connecting rod 2110 through a bevel gear transmission connection. When the heated water falls into the treatment tank 20 through the delivery pipe 19, the long rotating rod 15 drives the vertical transmission column 2114 to rotate through the bevel gear. The vertical transmission column 2114 drives the connecting rod 2110 to rotate through the bevel gear. The connecting rod 2110 drives the second gear 2111 on its surface to rotate. After the water enters the treatment tank 20, it passes through the filter screen 218 on the surface of the frame 217. The filter screen 218 can filter and block impurities in the water, and the scoop net 219 can precipitate impurities. The filtered water returns to the interior of the tank body 4 from the connecting pipe 22 on the other side of the treatment tank 20. This cycle heats the water and raises the water temperature. Under the action of two atmospheres of pressure, the water temperature can only boil when it rises to 120°C. The 100°C required by the test will not produce a large number of bubbles. At the same time, during the rotation of the second gear 2111, the teeth of the second gear 2111 are engaged with the first gear 213, and the second gear 2111 drives the first gear 213 to rotate. Then the first gear 213 drives the rotating column 212 to rotate, so that the rotating column 212 drives the connecting frame 216, the frame 217 and the filter screen 218 to rotate in a direction away from the treatment tank 20. At the same time, the scoop net 219 moves with the impurities, and the lever 214 also rotates with it, and the torsion spring 215 is in a compressed state. Then the opening of the scoop net 219 faces downward, and under the action of gravity, the impurities in the scoop net 219 fall down.Several collecting boxes 23 are placed on the top of the support table 29. Impurities enter the collecting boxes 23 for collection. After that, the part of the second gear 2111 without teeth contacts the first gear 213. Under the reaction force of the torsion spring 215, the rotating column 212 drives the frame 217 and the filter 218 to rotate in the opposite direction and re-enter the processing tank 20. At the same time, the notches on the surfaces of the multiple second gears 2111 face different angles. Therefore, the angles of different frames 217, filter screens 218 and scoop nets 219 are also different at the same time. Some play a filtering role in the processing tank 20, and some have already been used to dump impurities outside the processing tank 20. Therefore, multiple frames 217, filter screens 218 and scoop nets 219 work alternately to filter, scoop and dump impurities in the water, avoid a large amount of impurities causing turbidity in the water and affecting the detection condition, and also allow the water to be recycled, reducing the waste of water resources.

[0046] The water temperature sensor 28 detects the water temperature. When the water temperature is about 100°C displayed on the control panel 5, the hydraulic rod 9 is turned on, and its output shaft is extended to drive the long board 11 to descend.

The fixed frame 261 is bolted to both sides of the long board 11, the rack 264 and the fixed frame 261 are bolted to each other, the number of vertical plates 265 is several and they are bolted to the top of the inner cavity of the shell 1, the horizontal transmission column 266 is rotatably connected to the vertical plate 265, and one end of the horizontal transmission column 266 is fixed with a transmission gear 267 that meshes with the rack 264, the bottom end of the vertical rotation rod 252 is connected to the horizontal transmission column 266 through a bevel gear transmission, and the transmission mechanism 26 also includes a The vertical plate 262 has a blocking plate 263 bolted to the top thereof. Before the long plate 11 is lowered, the blocking plate 263 is located at the entrance of the inlet pipe 258 to achieve blocking, and the high-pressure gas inside the shell 1 cannot enter. During the descent of the long plate 11, it drives the fixing frame 261, the vertical plate 262, the blocking plate 263 and the rack 264 to descend together, and the blocking plate 263 is disengaged from the entrance of the inlet pipe 258. At the same time, the rack 264 drives the transmission gear 267 to rotate, and the transmission gear 267 drives the horizontal transmission column 266 to rotate. A slide rail 268 is also bolted to the top of the inside of the shell 1, and the rack 264 is slidably connected to the surface of the slide rail 268 to increase the stability of the rack 264 during the up and down movement. The horizontal transmission column 266 is driven by a bevel gear. The vertical rotating rod 252 is driven to rotate, and the vertical rotating rod 252 drives the driving rod 253 above to rotate. The driving rod 253 drives one end of the transmission rod 254 to make a circular motion, and the transmission rod 254 drives the movable rod 255 at the other end to make a reciprocating motion. The movable rod 255 slides back and forth along the inner wall of the sliding sleeve 256, thereby driving the piston plate 257 to move back and forth inside the box body 251. In the process of the piston plate 257 moving toward the side close to the sliding sleeve 256, the internal volume of this side increases and the air pressure decreases, which makes the gas inside the shell 1 pass through the inlet pipe 258 and push open the first one-way door 2512 to enter the box body 251. Since the second one-way door 2513 cannot be opened to the inner side of the box body 251, the air in the short tube 259 will not enter. When the piston plate 257 moves toward the side away from the sleeve 256, the volume of the side decreases, the air pressure increases, and the second one-way door 2513 is pushed outward. At the same time, the first one-way door 2512 cannot be opened in the direction away from the inside of the box 251, and the gas is transported to the short tube 259. Therefore, when the long board 11 descends, the piston plate 257 is driven to reciprocate through the cooperation of the rack 264, the transmission gear 267, the horizontal transmission column 266 and other structures. At the same time, under the action of the first one-way door 2512 and the second one-way door 2513, the high-pressure gas inside the shell 1 is transported to the short tube 259, and then the high-pressure gas enters the pump body to be tested through the main transmission pipe 2510 and the hose 2511.During the descent of the long board 11, the connecting board 101, the arc board 104 and the fixed pump body can also be lowered. The pump body is tested in the water at 100°C. At the same time, the long board 11 stops descending, and the extraction and delivery mechanism 25 stops delivering gas to the pump body. There are 2 atmospheres of pressure in the shell 1. Water will not boil at around 100°C and produce a large number of bubbles. The staff can observe whether bubbles are generated in the water through the glass window 3 or the picture taken by the camera 24. If bubbles appear, it means that the seal of the pump body is not good. If no bubbles appear, it means that it is qualified, thereby achieving the effect of testing the air tightness of the pump body in a high temperature environment. At the same time, the high-pressure gas in the shell 1 can also be used to test the air tightness of the pump body.

[0047] During the detection process, the drive motor 18 is continuously turned on, and the water is still circulating and flowing slowly, which not only continues to heat and keep warm, but also can remove impurities in the water. If the water temperature in the pool body 4 exceeds 110°C, it may boil. At this time, the drive motor 18 needs to be temporarily turned off to stop the circulation and heating of the water.

[0048] After the test is completed, one side of the surface of the gas pipe 8 is also connected to an exhaust pipe 30, and a solenoid valve 31 is installed on the surface of the exhaust pipe 30. The solenoid valve 31 is opened and the valve on the surface of the gas pipe 8 is closed. The gas inside the shell 1 passes through the part of the gas pipe 8 and is discharged from the exhaust pipe 30. Then, the sealing door 2 is opened, and the hydraulic rod 9 is turned on to drive the long board 11 to rise, so that the pump body leaves the water, and the screw rod 103 is turned to let the pressure plate 105 rise, and then the fixation of the pump body is released, and the next pump body to be tested is replaced.
