Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and particularly relates to a cylinder of a piston compressor. Background Art

[0002] A piston air compressor provides a gas source power and is the core equipment in a pneumatic system and the main body in a mechanical and electrical air source device. It is a device that converts the mechanical energy of the prime mover into gas pressure energy and is a pneumatic pressure generating device for compressed air. A large amount of heat is generated during the compression of air, and the increase in temperature will accelerate the loss of the equipment. Most of the existing cylinders use water cooling or air cooling for heat dissipation. Among them, water cooling is suitable for occasions with large heat dissipation requirements. By setting a water jacket outside the cylinder and allowing cooling water to circulate in the water jacket to absorb the heat generated by the cylinder, the temperature of the cylinder is reduced; while air cooling is suitable for occasions with not particularly large heat dissipation requirements. Heat dissipation fins are arranged outside the cylinder, and natural wind or forced convection by a fan is used for heat dissipation. However, the heat dissipation methods of the cylinders in the existing technology are usually unique, resulting in users being unable to selectively use the heat dissipation method of the cylinder according to the actual usage requirements. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art. The purpose is to provide a cylinder of a piston compressor. By using the detachable connection between the cover plate and the cylinder block, the cylinder block can select whether to use air cooling or water cooling according to the actual working requirements, avoiding unnecessary waste of resources.

Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in combination with the embodiments and the accompanying drawings. The illustrative embodiments of the present utility model and their descriptions are only used to explain the present utility model and do not constitute a limitation to the present utility model.

[0031] Embodiment

[0032] As Figures 1 to 6 shown, the present utility model includes a cylinder block 1, a chamber 13 for the reciprocating movement of a piston is provided inside the cylinder block 1, heat dissipation grooves 17 are provided on both sides of the cylinder block 1, and the two heat dissipation grooves 17 are communicated through a channel 16. A plurality of water channels 14 communicated with the heat dissipation grooves 17 are also provided on the cylinder block 1, and plugs 10 are arranged in some of the water channels 14; it further includes cover plates 18 on both sides of the cylinder block 1. The cover plates 18 are detachably connected to the cylinder block 1, and the cover plates 18 are used to block the openings of the heat dissipation grooves 17.

[0033] In the prior art, the heat dissipation method of the cylinder block 1 is usually fixed. Generally, air cooling or water cooling is used for heat dissipation. This causes users to be unable to selectively use the heat dissipation method according to the actual usage requirements of the cylinder block, resulting in unnecessary waste of some resources. Therefore, in this technical solution, heat dissipation grooves 17 are provided on both sides of the existing cylinder block 1. The provided heat dissipation grooves 17 are close to the cavity inside the cylinder block 1. In this way, the heat generated when the piston in the cavity 13 works can be transferred to the heat dissipation grooves. At the same time, covers 18 are provided at the openings of the heat dissipation grooves 17, and the covers 18 are detachably connected to the cylinder block 1. Therefore, when the heat generated when the piston in the cylinder block 1 works is small, the covers 18 provided on both sides of the cylinder block 1 are removed, so that the heat dissipation grooves 17 are exposed. In this way, the natural wind or the cold air generated by the fan acts in the heat dissipation grooves, and heat exchange is carried out with the heat transferred from the inner wall of the cavity 13 to the heat dissipation grooves, thereby achieving the purpose of air cooling the cylinder block 1.

[0034] When the working intensity of the cylinder block 1 is high and the generated heat is large, the provided covers 18 are installed on both sides of the cylinder block 1, and the openings of the heat dissipation grooves 17 are blocked by the provided covers 18, so that the heat dissipation grooves are in a sealed state at this time. Then, the water pipe connected to the water pump is inserted into one of the water channels 14 of the cylinder block 1, and the water pipe can be used to convey cooling water into one of the heat dissipation grooves 17. After the cooling water enters one of the heat dissipation grooves 17, heat exchange is carried out between the cooling water and the heat transferred to the heat dissipation grooves. Then, the cooling water enters another heat dissipation groove 17 through the provided channel 16, and continues to carry out heat exchange with the heat in the other heat dissipation groove 17. Finally, the cooling water is discharged to the outside through the water channel 14, thereby achieving the purpose of water cooling the cylinder block 1.

[0035] Preferably, there are four water channels 14, and the four water channels 14 are evenly distributed on the upper and lower surfaces of the cylinder block 1, and the two water channels 14 on the same side are both communicated with the same heat dissipation groove. Since the piston in the cavity 13 will have a certain amount of wear after working for a long time, this causes different amounts of heat to be generated at different positions in the cavity 13 when the worn piston moves in the cavity 13. During the process of cooling the cylinder block by cooling water, as the cooling water continuously flows in the cylinder block 1, the water temperature will gradually increase, resulting in a decrease in the heat dissipation effect of the cylinder block 1. To solve the above problems, when Figure 4When the heat generated on the left inner wall of the cavity 13 of the cylinder block 1 is greater than that on the right side, a plug 10 is installed in the water channel 14 on the left side of the upper surface of the cylinder block 1, and at the same time, a plug 10 is installed in the water channel 14 on the right side of the lower surface of the cylinder block 1. Then, an external water pipe is connected to the water channel 14 on the left side of the lower surface of the cylinder block 1, and cooling water is introduced into the heat dissipation groove 17 on the left side of the cylinder block 1 through the water pipe, so that the cooling water preferentially enters the heat dissipation groove 17 on the left side, ensuring that the cooling water at a lower temperature can preferentially exchange heat with the heat dissipation groove 17 on the left side at a higher temperature. After the heat exchange in the left heat dissipation groove 17, the cooling water enters the heat dissipation groove 17 on the right side through the channel 16, and then continues to exchange heat with the relatively stable and lower right heat dissipation groove 17. Finally, the cooling water is discharged to the outside through the water channel 14 on the right side of the upper surface of the cylinder block 1.

[0036] Similarly, when the heat generated on the right inner wall of the cavity 13 of the cylinder block 1 is greater than that on the left side, the plug 10 in the water channel 14 on the left side of the upper surface of the cylinder block 1 can be unscrewed and installed in the water channel 14 on the right side of the upper surface of the cylinder block 1. Then, the plug 10 in the water channel 14 on the right side of the lower surface of the cylinder block 1 is unscrewed and installed at the left side of the lower surface of the cylinder block 1. Then, an external water pipe is connected to the water channel 14 on the right side of the lower surface, so that the water channel 14 on the left side of the upper surface of the cylinder block 1 is the cooling water discharge port. In this way, it is ensured that the cooling water can preferentially enter the heat dissipation groove 17 on the right side of the cylinder block 1, exchange heat with the relatively high-temperature right heat dissipation groove 17, and then exchange heat with the left heat dissipation groove 17, thereby improving the heat dissipation effect of the cylinder block 1.

[0037] Preferably, the provided cover plate 18 is connected to the cylinder block 1 by bolts, thereby realizing the detachable connection between the cover plate 18 and the cylinder block 1.

[0038] A cylinder liner 8 for installing a piston is further provided in the cavity 13 of the cylinder block 1. One end of the cylinder block 1 is further provided with a cylinder head 6. The cylinder head 6 is connected to the cylinder block 1 by bolts and fixes the cylinder liner 8 in the cylinder block 1.

[0039] In this embodiment, by using the provided cylinder liner 8, it can be ensured that during the movement of the piston in the cavity 13 of the cylinder block 1, the generated heat is transferred to the cylinder liner 8, and then the cylinder liner 8 transfers the heat to the periphery of the heat dissipation groove 17, so as to use the heat dissipation groove 17 to dissipate heat and cool down the inside of the cylinder block 1.

[0040] There are also two cavities 12 provided in the cylinder block 1, and both of the two cavities 12 communicate with the cavity 13 of the cylinder block 1; there are also several mounting holes provided on the cylinder block 1 that communicate with the cavities 12, and pressure valve covers 5 for installing air valves are provided in the mounting holes; there are also valve covers 2 on the cylinder block 1 with the same number as the number of mounting holes, there are also several stud bolts provided on the cylinder block 1, the valve covers 2 are sleeved on the stud bolts, and nuts 3 are also provided on the stud bolts, and the nuts 3 are used to fix the valve covers 2 on the cylinder block 1.

[0041] In this embodiment, the pressure valve cover 5 provided can fix the air valve in the cylinder block 1, so that during the reciprocating movement of the piston in the cylinder block, the purpose of gas supercharging can be achieved; the valve cover 2 provided facilitates the loading and unloading of the pressure valve cover 5.

[0042] There is also an air inlet and an exhaust port 9 provided on the cylinder block 1, the air inlet communicates with one of the cavities 12, and the exhaust port 9 communicates with the other cavity 12.

[0043] There are several heat dissipation fins 15 provided in the heat dissipation groove 17, and the heat dissipation fins 15 are distributed on the inner wall between the cavity 13 and the heat dissipation groove 17.

[0044] In this embodiment, in order to further improve the heat dissipation effect of the cylinder block 1, heat dissipation fins 15 are provided in the heat dissipation grooves 17. In this way, the heat generated during the operation of the piston can be transferred to each heat dissipation fin 15. When the cylinder block 1 uses cold air as the heat dissipation method, the cold air generated by natural wind or a fan acts in the heat dissipation groove 17, and the cold air can exchange heat with the heat transferred to the heat dissipation fins 15, thereby increasing the acting area of the cold air and further improving the heat dissipation effect of the cylinder block 1; when the cylinder block 1 uses cold water as the heat dissipation method, the cooling water entering the heat dissipation groove 17 exchanges heat with the heat transferred to the heat dissipation fins 15, thereby increasing the cross-sectional area of the cooling water in the heat dissipation groove 17 and further improving the heat dissipation effect of the cylinder block 1.

[0045] There is also a groove provided on the side wall of the cover plate 18 facing the heat dissipation groove 17, and a moving plate 19 is also provided in the groove, and the moving plate 19 is used to adjust the size of the heat dissipation cavity formed by the cover plate 18 and the heat dissipation groove 17.

[0046] When the cylinder body 1 adopts cold water as the heat dissipation method, in order to increase the flow rate of the cooling water in the heat dissipation groove 17, thereby improving the heat dissipation of the cooling water to the cylinder body 1, a groove and a movable plate 19 are provided on the cover plate 18. The shape of the groove is consistent with the shape of the movable plate 19, and the movable plate 19 can move in the groove toward the heat dissipation fins 15. In this way, when it is necessary to increase the flow rate of the cooling water in the heat dissipation groove 17 to improve the heat dissipation effect on the cylinder body 1, the movable plate 19 located in the groove is moved to force the movable plate 19 to extend out of the groove, thereby reducing the spacing between the movable plate 19 and the heat dissipation fins 15, thereby reducing the size of the space formed by the movable plate 19 and the heat dissipation groove 17. When the space formed by the movable plate 19 and the heat dissipation groove 17 is reduced, the flow rate of the cooling water in the heat dissipation groove 17 will increase, so that the cooling water can pass through the two heat dissipation grooves 17 faster, thereby taking away more heat from the cylinder body 1 and improving the heat dissipation effect of the cylinder body 1.

[0047] The cover plate 18 is further provided with an adjusting rod 22 , which is threadedly connected to the cover plate 18 , and is used to push the moving plate 19 to move in the groove.

[0048] In order to enable the movable plate 19 to move in the groove in this embodiment, an adjusting rod 22 is provided on the cover plate 18. When the movable plate 19 needs to be pushed to move, the adjusting rod 22 is rotated so that the adjusting rod 22 moves toward the movable plate 19 and then pushes the movable plate 19 to move.

[0049] The adjusting rod 22 extends outward from the cover plate 18 and is provided with a limit block 20 .

[0050] In this embodiment, in order to prevent the adjusting rod 22 from completely pushing the movable plate 19 out of the groove, a limit block 20 is provided on the adjusting rod 22. When the limit block 20 on the adjusting rod 22 is in contact with the cover plate 18, the limit block 20 will limit the further movement of the adjusting rod 22, thereby preventing the movable plate 19 from being completely moved out of the groove.

[0051] An elastic member 21 is further disposed in the groove, one end of the elastic member 21 is connected to the bottom of the groove, and the other end of the elastic member 21 is connected to the moving plate 19 .

[0052] In order to ensure that the movable plate 19 can be retracted into the groove in this embodiment, an elastic member 21 is also provided. The elastic member 21 is a spring. When the adjusting rod 22 is rotated in the opposite direction so that the adjusting rod 22 retreats away from the heat sink fins 15, the pulling force generated by the elastic member 21 can pull the movable plate 19 back into the groove.

[0053] A sealing ring is further provided between the movable plate 19 and the inner wall of the groove, and the sealing ring is sleeved on the movable plate 19; a pressure relief hole 23 communicating with the groove is further provided on the cover plate 18.

[0054] In this embodiment, in order to prevent the cooling water introduced into the heat dissipation groove 17 from leaking through the gap between the movable plate 19 and the groove, a sealing ring is further provided on the movable plate 19, and the sealing ring can prevent the cooling water in the heat dissipation groove 17 from leaking from the movable plate 19.

[0055] At the same time, in order to ensure that the movable plate 19 can move normally in the groove, a pressure relief hole 23 is further provided on the movable plate 19 to ensure that the negative pressure generated during the movement of the movable plate 19 in the groove can suck external gas into the groove through the pressure relief hole 23.

[0056] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
