Description

Technical Field

[0001] The invention relates to the technical field of compressors, and in particular to a piston compressor with a damping mechanism. Background Art

[0002] The piston compressor is a common fluid machine, widely used in refrigeration, air conditioning, chemical industry and other industries to compress gas or other media. Its working principle is mainly to change the volume of the working chamber through the reciprocating motion of the piston in the cylinder, thereby achieving the purpose of increasing the gas pressure. However, since the piston generates inertia and friction during the movement, the periodic changes of these forces will cause the compressor to vibrate, causing noise and affecting the stability and life of the equipment. Therefore, damping shock absorbers are installed on the compressor to absorb and slow down the impact force and vibration generated by the piston movement to varying degrees;

[0003] However, in actual use, the connection between the crankshaft and the connecting rod in the casing is prone to loosening and deviation due to long-term operation, which in turn causes irregular movement of the piston at the end of the connecting rod and causes vibration, thereby increasing the overall vibration amplitude of the compressor and increasing noise pollution. Therefore, we propose a piston compressor with a shock absorbing mechanism to solve the above-mentioned problems. Summary of the invention

[0033] Reference Figure 1-8A piston compressor with a shock absorbing mechanism comprises a pump body 1, a driving shaft 20 is arranged on the pump body 1, one end of the driving shaft 20 is rotatably connected with a connecting rod 21 through a bearing, a first piston 22 is arranged at one end of the connecting rod 21, and the first piston 22 is slidably connected in the pump body 1, a valve port 23 is arranged on the top of the pump body 1, a heat sink 24 is arranged on the surface of the pump body 1, a damper 25 is installed at the bottom of the pump body 1, an air induction component 3 arranged in the pump body 1, one end of which is sleeved on the outside of the pump body 1 for disturbing the internal heat of the pump body 1; an intermittent component 4 is arranged on the air induction component 3, and the intermittent component 4 is driven to intermittently move to lubricate the connecting rod 21 when the air induction component 3 reciprocates; an auxiliary component 5 is also arranged in the pump body 1, and the intermittent component 4 can also drive the auxiliary component 5 to run synchronously in the reciprocating state to recover the lubricating liquid dripping in the pump body 1.

[0034] In the present invention, the driving shaft 20 can drive the connecting rod 21 to rotate, and the connecting rod 21 drives the first piston 22 to reciprocate inside the pump body 1, thereby introducing air into the pump body 1 and then discharging it from the exhaust port to achieve normal operation of the equipment. Considering that in actual use, the equipment is prone to vibration when it is running, a damper 25 is arranged at the bottom of the pump body 1 to buffer and reduce the vibration generated by the operation of the internal components of the pump body 1, thereby reducing the damage caused by the vibration of the equipment to other components. There are many reasons for the vibration of the compressor equipment. Among them, the driving shaft 20 and the connecting rod 21 are generally connected by the crank pin journal and the center rotating pin crosshead pin of the crosshead component. However, when the components are in operation for a long time, the connection between the components is prone to wear and heat, which in turn affects the trajectory of the movement of the components, thereby causing the equipment to vibrate. Therefore, it is very important to ensure that the driving shaft 20 and the connecting rod 21 operate normally. Although the prior art seals the pump body 1 as a whole and then injects lubricating oil, subsequent maintenance is more troublesome, and the lubricating oil is stored in the pump body 1, which is prone to dirt deposition.

[0035] Therefore, the above scheme is adopted, and an air inlet component 3 is arranged inside the pump body 1. When the driving shaft 20 rotates, the air inlet component 3 can be driven to run synchronously and make up and down reciprocating motion. When the air inlet component 3 is running, external air can be introduced into the interior of the pump body 1, and a part of the air flow is transported to the interior of the pump body 1 to disturb the heat generated inside the pump body 1, thereby accelerating the heat dissipation. At the same time, the connection between the driving shaft 20 and the connecting rod 21 can be auxiliary cooled to ensure the normal operation of the mechanism, and another part of the air flow can be guided to the outside to blow air to the heat sink 24 to prevent dust accumulation, improve the heat dissipation effect, and avoid deformation of the pump body 1. When the air bleed component 3 is running, it can drive the intermittent component 4 to run synchronously. The intermittent component 4 makes intermittent movement to spray the pre-stored lubricating oil intermittently. On the one hand, it effectively saves maintenance costs, and lubricates the connection between the connecting rod 21 and the drive shaft 20 to reduce the wear between the components, thereby effectively reducing the amplitude generated by the operation of the equipment, improving the shock absorption effect, and reducing the vibration source. At the same time, the air bleed component 3 can also drive the auxiliary component 5 to run during operation, and the fallen lubricating oil can be collected and reused, thereby avoiding waste of resources, automating operation, reducing maintenance costs, and preventing the lubricating oil from being deposited in the pump body 1 and affecting the equipment.

[0036] In a preferred embodiment, referring to Figure 3 , Figure 4 , Figure 7 and Figure 8 The air induction assembly 3 includes a first connecting cylinder 31 installed in the pump body 1, the interior of the first connecting cylinder 31 is slidably connected to the second piston 32, a lifting rod 33 is fixed to the top of the second piston 32, one end of the lifting rod 33 is fixed to a connecting plate 34, an extrusion spring 35 is fixed between the connecting plate 34 and the first connecting cylinder 31, the extrusion spring 35 is sleeved on the surface of the lifting rod 33, a circular block 36 is attached to the top surface of the connecting plate 34, the axis of the circular block 36 is installed together with one end of the driving shaft 20, and an auxiliary part is provided at one end of the first connecting cylinder 31, and the auxiliary part includes a connecting plate 34 connected to the first connecting cylinder 31. An air duct 37 is connected at one end of the connecting tube 31, and one end of the air duct 37 passes through the pump body 1 and extends to the outside. A connecting tube 371 is fixedly connected to one side of the first connecting tube 31, and the end of the connecting tube 371 is connected to an air delivery channel 38. The air delivery channel 38 is opened on the inner wall of the pump body 1, and an air outlet at one end of the air delivery channel 38 is connected to an injection disc 39, and a nozzle 391 is installed on the surface of the injection disc 39. A protective cover 392 is provided on the surface of the pump body 1 outside the nozzle 391. A shunt pipe 393 is fixed to one end of the first connecting tube 31, and an air guide head 394 is provided at the end of the shunt pipe 393.

[0037] With the above solution, when the drive shaft 20 rotates, the circular block 36 is driven to rotate synchronously. As the circular block 36 rotates and squeezes the connecting plate 34, the second piston 32 slides inside the first connecting cylinder 31. In this reciprocating state, the external air is introduced into the first connecting cylinder 31 through the air duct 37, and then transported to the air guide head 394 through the shunt pipe 393 for spraying. The air guide head 394 points to the connection between the drive shaft 20 and the connecting rod 21. In this way, on the one hand, the cold air sprayed into the pump body 1 can be used to disturb the heat generated in the pump body 1, accelerate the heat dissipation, and cool the pump body 1. The temperature is lowered and the connection between the connecting rod 21 and the driving shaft 20 is directly blown to improve the cooling effect. When the air introduced into the first connecting cylinder 31 is squeezed by the second piston 32, a part of the airflow is output through the air duct 37, and then passes through the air delivery channel 38 and finally enters the jet disk 39, and then is sprayed out through multiple nozzles 391 to clean the dust retained on the surface of the heat sink 24. At the same time, the blown airflow blows on the heat sink 24 to accelerate the conduction heat dissipation effect of the heat sink 24, effectively alleviate the friction heat deformation at the sliding connection between the pump body 1 and the first piston 22, and improve the stability of the overall structure.

[0038] It should be noted that a one-way valve is provided at the connection between the air duct 37 , the connecting pipe 371 and the first connecting tube 31 to ensure the normal operation of the mechanism.

[0039] In a preferred embodiment, referring to Figure 5 , Figure 6 and Figure 7 The intermittent component 4 includes a rack 41 fixed to one side of the connecting plate 34, a rotating gear 42 is meshed on the surface of the rack 41, a ratchet 43 is provided on one side of the rotating gear 42, one side of the ratchet 43 rotates a limiting plate 44 through a bearing, a bump 45 is installed on the surface of the ratchet 43, and an oil spraying member is provided on the surface of the bump 45. The oil spraying member includes a moving rod 46 arranged on the surface of the bump 45, an extrusion ring 48 is fixed to the end of the moving rod 46, an air bag 49 is attached to the top of the extrusion ring 48, the air bag 49 is installed on the inner wall of the pump body 1, a liquid spraying head 491 is installed on the surface of the air bag 49, a liquid inlet pipe 492 is embedded in the inner wall of the pump body 1, one end of the liquid inlet pipe 492 is fixedly connected to the air bag 49, a return spring 47 is sleeved on the surface of the moving rod 46, one end of the return spring 47 is fixedly connected to the moving rod 46, and the other end of the return spring 47 is fixedly connected to the extrusion ring 48.

[0040] By adopting the above scheme, when the connecting plate 34 moves up and down, the rack 41 can be driven to move synchronously, and the rack 41 meshes with the rotating gear 42 to drive the rotating gear 42 to rotate. The rotating gear 42 cooperates with the ratchet 43, so that when the rotating gear 42 rotates clockwise, it will not drive the ratchet 43 to rotate. When the rotating gear 42 rotates in the opposite direction, it drives the ratchet 43 to rotate, and so on. When the protrusion 45 on the ratchet 43 contacts the moving rod 46, the moving rod 46 is moved up by the extrusion force, and then the extrusion ring 48 is synchronously moved up to squeeze the airbag 49, and the lubricating oil pre-stored in the airbag 49 is sprayed out through the spray head 491, and the spray head 491 points to the connecting rod 2 1. The lubricating oil on the connecting rod 21 flows along the surface to the connection with the drive shaft 20, lubricating the connection part, reducing the wear caused by the connection movement between the parts, improving the stability of the structure, and reducing the amplitude. Compared with the existing technology, this solution can eliminate or alleviate the source of vibration from the source, and facilitate maintenance. There is no need for manual disassembly and maintenance operations, which improves the working efficiency of the equipment. Moreover, using this structural design, there is no need for additional power source, and the intermittent motion mode for a long period of time saves maintenance costs and avoids waste of resources. A one-way valve can be set at the liquid inlet pipe 492 to facilitate the introduction of airflow into the airbag 49 when the airbag 49 is reset, so as to ensure the normal operation of the mechanism.

[0041] In a preferred embodiment, referring to Figure 4 , Figure 7 and Figure 8 The auxiliary component 5 includes a movable rod 51 fixed to the bottom of the connecting plate 34, a third piston 52 is fixed to the bottom of the movable rod 51, the third piston 52 is slidably connected in the second connecting cylinder 53, the second connecting cylinder 53 is installed on the bottom inner wall of the pump body 1, a connecting pipe 55 is fixed to one end of the second connecting cylinder 53, a collecting box 56 is fixed to one end of the connecting tube 55, the collecting box 56 is installed on the bottom inner wall of the pump body 1, a reflux member is provided at one end of the second connecting cylinder 53, the reflux member includes a reflux pipe 54 connected to the second connecting cylinder 53, the reflux pipe 54 is fixedly connected to the airbag 49, and a one-way valve is provided at the connection between the reflux pipe 54, the connecting pipe 55 and the second connecting cylinder 53.

[0042] By adopting the above scheme, when the connecting plate 34 is lifted and lowered, the movable rod 51 is driven to operate synchronously, so that the third piston 52 slides inside the second connecting cylinder 53, and the lubricating oil collected at the collecting box 56 is sucked into the second connecting cylinder 53 through the connecting pipe 55. Then, as the third piston 52 is pressed downward, the lubricating oil is transported to the inside of the airbag 49 through the reflux pipe 54, thereby realizing the collection of the lubricating oil and facilitating its reuse. On the other hand, it can also prevent the lubricating oil from being deposited inside the pump body 1, effectively reducing the maintenance cost.

[0043] In a preferred embodiment, referring to Figure 5 and Figure 7 A fixed plate 6 is fixed inside the pump body 1, a limit block 60 is fixed on one side of the fixed plate 6, the moving rod 46 is slidably connected in the limit block 60, a T-shaped groove 7 is provided on the surface of the fixed plate 6, a T-shaped slider 8 is slidably connected inside the T-shaped groove 7, one end of the T-shaped slider 8 is fixedly connected to the connecting plate 34, a heat dissipation port 9 is provided on one side of the pump body 1, and a dustproof net is arranged inside the heat dissipation port 9.

[0044] In the present invention, the T-shaped groove 7 and the T-shaped slider 8 are provided to limit the movement of the connecting plate 34, thereby improving the stability of the structure, and the connecting shaft is installed at the axis of the rotating gear 42 and is installed on one side of the fixed plate 6. The heat dissipation port 9 is provided to facilitate the discharge of heat from the inside of the pump body 1 and accelerate the dissipation of heat from the pump body 1.
