Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning compressor detection, and in particular to a leakage detection device for an air-conditioning compressor. Background Art

[0002] The air conditioning compressor is the core component of the air conditioning system. Its main function is to compress the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gas, thereby improving the refrigeration efficiency. The air conditioning compressor usually needs to be leak-tested to ensure that it is well sealed. Once the high-pressure refrigerant gas inside the compressor leaks, it will cause system failure and reduced efficiency.

[0003] The existing leak detection method is generally as follows: first seal the exhaust port of the air-conditioning compressor, then connect the air inlet to the pressure device through a hose, and the pressure device can inject gas (such as air, nitrogen, etc.) into the air-conditioning compressor to increase the pressure inside the compressor. Then immerse the air-conditioning compressor in a pool of water, start the pressure device and observe whether bubbles are generated in the pool, or leave it for a while after the pressure is pressed to observe the changes in the pressure gauge of the pressure device. If there are bubbles, there is a sealing problem, otherwise there is no bubble. If the value of the pressure gauge on the pressure device decreases, there is a sealing problem, otherwise there is no change.

[0004] An air-conditioning compressor is usually composed of a tank and a main cylinder. The tank is connected to the main cylinder by a curved pipe, and the tank is made up of two parts. The main cylinder is made up of an end cover and a cylinder body. These connection positions are key positions for sealing, and the air-conditioning compressor is often subject to vibration during operation, or shaking during transportation and installation. At this time, it is inconvenient to measure whether these connection positions are sealed reliably. If slight leaks occur at these connection positions due to vibration or shaking, it will affect the normal use of the air-conditioning compressor. The existing static water immersion leak detection can only show the sealing of the compressor in a stationary state, ignoring the sealing performance in other states, and the accuracy of the leak detection is poor. To this end, we propose a leak detection device for air-conditioning compressors. Summary of the invention

[0034] The driving assembly includes an L-shaped block 11 and an arc-shaped tooth plate 30. The L-shaped block 11 is fixedly connected to the upper edge of the vertical wall of the Z-shaped plate 10 located in the front, and a motor 32 is fixedly installed through the vertical wall of the L-shaped block 11.

The arc-shaped tooth plate 30 is fixedly connected to the top of the swing plate 26, and the arc-shaped tooth plate 30 and the gear 31 are meshed with each other.

[0035] Working principle: First, start the two electric push rods 9 to drive the two Z-shaped plates 10, the semicircular ring 19 and the semicircular bracket 13 to move up together until they reach a height that is easy for the staff to reach. The swing plate 26, the threaded sleeve 20, the stud 12, the connecting ring 33 and the rubber ring 34 connected to the Z-shaped plate 10 in the front will move up accordingly, and then the compressor body 5 will be placed on the semicircular bracket 13, and the tank of the compressor body 5 will face upward, and then the threaded rod 29 will be rotated, and the threaded rod 29 will move toward the compressor body 5 in the fixed block 28, and the threaded rod 29 will also drive the arc clamping plate 27 to slide on the inner arc surface of the semicircular bracket 13 and will contact the compressor body 5, and then the arc clamping plate 27 will push the compressor body 5 to fit with the semicircular ring 19 to release the threaded rod 29, at this time The front and rear position of the compressor body 5 can be limited between the semicircular ring 19 and the arc clamping plate 27, and the compressor body 5 can rotate on the inner arc surface of the semicircular bracket 13. Then, rotate the stud 12 outward to move it toward the tank container in the threaded sleeve 20. At the same time, rotate the compressor body 5 to make the exhaust port on the tank container correspond to the stud 12 until the stud 12 slides and is inserted into the exhaust port of the tank container. Then, rotate the connecting ring 33 toward the tank container until the connecting ring 33 drives the rubber ring 34 to tightly press against the exhaust end of the tank container, thereby sealing the exhaust end of the tank container. At this time, the compressor body 5 can be kept fixed. Then, connect the air pumping end of the electric press 1 to the air inlet end of the compressor body 5 through a hose. Finally, inject a proper amount of water into the pool 2.

[0036] Then, the two Z-shaped plates 10, the semicircular ring 19 and the semicircular bracket 13 are driven downward by the two electric push rods 9, so that the compressor body 5, the swing plate 26, the threaded sleeve 20, the stud 12, the connecting ring 33 and the rubber ring 34 will move downward accordingly, and the state after the downward movement is as follows. Figure 2 As shown (it should be noted that the hose connecting the air pump end of the electric press 1 and the air inlet end of the compressor body 5 is not Figure 1 or Figure 2 The hose and how the hose is connected between the air pumping end of the electric press 1 and the air inlet end of the compressor body 5 are well-known prior art and will not be elaborated on herein). At this time, the compressor body 5 will be completely immersed in water to prepare for leak detection.

[0037] Then start the motor 28, which can drive the screw rod 17 to rotate. Since the threads on both sides of the outer wall of the screw rod 17 are symmetrically arranged, the U-shaped plates 15 threadedly sleeved on both sides of the outer wall of the screw rod 17 will move close to each other on the outer walls of the screw rod 17 and the guide column 16, and each U-shaped plate 15 will drive the connected connecting plate 14, multiple knocking columns 4 and connecting plate 2 18 to move toward the direction of the compressor body 5. One end of the multiple knocking columns 4 will first contact the outer wall of the compressor body 5, and the movement of the multiple knocking columns 4 will stop at this time. At this time, as the connecting plate 14 continues to move, the connecting plate 14 will squeeze the spring 22 connected to the multiple fixing rings 21. The multiple fixing rings 21 are respectively connected to the outer walls of the multiple knocking columns 4, and the connecting plate 14 will drive the protrusion 23 to leave the connecting plate 2 18 a little distance. At this time, turn off the motor 28. Figure 8 From the perspective of the above, one end of the multiple knocking columns 4 connected to each U-shaped plate 15 will contact multiple connection positions on the compressor body 5 respectively, and these multiple connection positions are key sealing positions on the compressor body 5. The specific connection positions are: the joints between the elbow pipe on the compressor body 5 and the storage tank and the main cylinder, the joints between the two parts of the storage tank, and the joints between the end cover on the main cylinder and the cylinder body. The compressor body 5 is composed of an elbow pipe, a storage tank, a main cylinder and an end cover, etc. This is the prior art and will not be elaborated. At this time, the entire component state is still as follows Figure 2 shown.

[0038] Then, the electric press 1 is started to inject a proper amount of gas into the compressor body 5 to increase the pressure inside the compressor body 5, and then the electric press 1 is turned off. Then, whether bubbles are generated in the water of the pool 2 is observed. If no bubbles are generated, the two motors 16 are started at this time. Each motor 16 will drive the rotating shaft 7, the rotating column 25 and the protrusion 23 to rotate. Each protrusion 23 will push the corresponding connecting plate 2 18 outward once. Then, when the connecting plate 2 18 moves outward, it will drive the connected multiple knocking columns 4 to move away from the outer wall of the compressor body 5, and the fixing rings 21 on the multiple knocking columns 4 will further The spring 22 is squeezed, and the ends of the multiple knocking columns 4 will leave the multiple connection positions on the compressor body 5. When the protrusion 23 rotates away from the corresponding connecting plate 18, the multiple knocking columns 4 and the connecting plate 18 will be reset under the action of the spring 22, and the multiple knocking columns 4 will knock on the multiple connection positions on the compressor body 5, and so on. Then observe whether there are bubbles in the water of the pool 2. If no bubbles are generated, the motor 2 8 can be used to drive the screw rod 17 to reverse, so that the two U-shaped plates 15 will move away from each other, and the multiple knocking columns 4 at the two locations will be driven to leave the compressor body 5. Then, the motor 32 is started, and the motor 32 can drive the gear 31 to rotate forward and reverse and reciprocate (the motor 32 is a reversible motor and can work in a cycle between forward and reverse rotation). Then, the gear 31 will drive the arc-shaped toothed plate 30 to swing back and forth counterclockwise and clockwise, thereby driving the swing plate 26 to swing back and forth counterclockwise and clockwise on the Z-shaped plate 10, and the swing plate 26 will drive the threaded sleeve 20, the stud 12, the connecting ring 33 and the rubber ring 34 to swing back and forth counterclockwise and clockwise (it should be noted that the swing plate 26 and the Z-shaped plate 10 are connected to each other). The rotation point corresponds to the center of the air inlet of the compressor body 5, and the center of the semicircular bracket 13 also corresponds to the center of the air inlet of the compressor body 5), then the stud 12 will drive the compressor body 5 to swing back and forth counterclockwise and clockwise on the semicircular bracket 13, and then turn off the motor 32 to stop the reciprocating swing of the compressor body 5, and then observe whether there are bubbles in the water of the pool 2. If there are no bubbles and the pressure value of the electric press 1 does not change, then there is no problem with the sealing of the compressor body 5, otherwise, there is a problem with the sealing of the compressor body 5.

[0039] Finally, the two Z-shaped plates 10, the semicircular ring 19 and the semicircular bracket 13 are driven upward by the two electric push rods 9, and the compressor body 5 is loosened and removed according to the opposite operation to the previous one, so as to perform a leak detection on the next compressor body 5.

[0040] It should be noted that when the air-conditioning compressor is being tested for leaks by immersion, the joints between the elbow and the tank and the main cylinder, the joints between the two parts of the tank, and the joints between the upper end cover and the cylinder body of the main cylinder, these key sealing positions will be subjected to knocking vibrations simultaneously, and the air-conditioning compressor will also be subjected to reciprocating swings, simulating the sealing performance of the air-conditioning compressor in other states such as the working state, and improving the accuracy of leak detection. At the same time, the air-conditioning compressor can also be positioned by its exhaust port before being immersed in water, so that the air-conditioning compressor can avoid displacement when simulating other states.
