Description

Technical Field

[0001] The present invention belongs to the technical field of compressor equipment, and in particular relates to a compressor. Background Art

[0002] Refrigeration compressors have gradually become essential key equipment in various sectors of the country's economic pillar industries. The cylinder block is the carrier of the compressor's moving pair. The quality of its structure directly affects the reliability of the cylinder block itself and the moving pair, and also affects the efficiency of the compressor. Therefore, the design or improvement of the cylinder block is particularly important.

[0003] Nowadays, compressors are used in small refrigeration equipment, so they must be matched with small compressors accordingly. However, the existing compressor cylinder seats are too large to be matched with small compressors. In addition, the existing compressor cylinder seats have uneven structural weight distribution, which will increase the overall vibration of the fuselage during operation. When processing the compressor cylinder seat, threaded holes are drilled on the legs of the cylinder seat. Too deep threaded holes make it difficult to discharge iron chips. If iron chips are still retained in the holes later, the compressor cylinder seat will be uneven after installation. Since the compressor needs to be smaller, the gas supply S-pipe inside the existing compressor cannot be better arranged inside it, resulting in the size of the small compressor being limited. After the small compressor is designed, the guide belt stability becomes worse due to the reduction in its internal construction weight, so it is necessary to increase its stability effect.

[0026] Since the compressor housing is filled with lubricating oil, when the present invention is operated for a long time, its internal mechanical parts will continue to be high in temperature. At this time, the lubricating oil also reduces its cooling effect. The lubricating oil inside the compressor housing is extracted by a circulating pump, and the lubricating oil enters the circulation pipe for circulation. At this time, the cooling fan is started, and the cooling fan cools the circulation pipe by wind, and also cools the compressor housing, and the heat sink improves the heat dissipation effect.

By providing the oil leakage hole 24, the lubricating oil is discharged downward, and at the same time, the heat dissipation of the motor can be improved.

[0046] The oil leakage hole 16 is opened on the left rear side of the annular groove 11 near the metal exhaust muffler chamber 22. In the present invention, the metal exhaust muffler chamber 22 is provided, which causes the left side of the cylinder base bracket 7 to be heavier. By providing the oil leakage hole 16 on one side of the metal exhaust muffler chamber 22, the weight there can be reduced, thereby stabilizing the cylinder base bracket 7 during operation.

[0047] A first boss 25 is provided at the upper end of the two front support leg connecting frames 12, and a second boss 26 is provided on the left and right sides of the upper surface of the pumping and pressing mechanism mounting seat 17. A third boss 27 is provided at the edge of the left side of the metal exhaust silencer chamber 22.

[0048] A notched opening 28 is provided between the two front support leg connecting frames 12 and at the front end portion of the cylinder block bracket 7. The S-tube 23 surrounds the left, front and right sides of the cylinder block bracket 7. The S-tube 23 body is provided with three downwardly bent sections.

By setting the upper end of the foot sleeve 806 into a cone shape, the support spring 802 can be better sleeved on the foot sleeve 806.

[0050] The middle parts of the four support bolts 801 pass through the four corners of the outer edge of the drive motor 9, and the upper ends of the support bolts 801 are fixed in the threaded holes 15 of the support legs. After the support bolts 801 are screwed upward, the support springs 802 are limited and fixed on the lower side of the drive motor 9.

By having the distance between the centers of the two legs 14 at the front and rear ends of the cylinder seat bracket 7 be 46-54 mm and the distance between the centers of the two legs 14 at the left and right ends of the cylinder seat bracket 7 be 62-68 mm, it is possible to install it in the casing of an existing small compressor.

[0052] The suction muffler 172 is box-shaped, and the rear side surface of the suction muffler 172 is arc-shaped. The material of the suction muffler 172 is PBT.

[0053] Four supporting platforms 29 are provided on the bottom side of the interior of the compressor housing 1, and the four supporting platforms 29 have the same height. Pits 30 are provided on the left and right sides of the front side of the housing top cover 2. The bottoms of the four cylinder seat supports 8 are supported on the four supporting platforms 29 to achieve the purpose of stable installation. The two pits 30 cause two lower bosses to appear on the inner side of the housing top cover 2. The two lower bosses are used to limit the upper ends of the two first bosses 25 respectively, thereby stabilizing the cylinder seat bracket 7.

[0054] like Figure 12 As shown, a cooling mechanism is provided in the middle of the left side of the compressor housing 1, and the cooling mechanism includes a circulation pipe 31 and a circulation pump 33.

The middle part of the circulation pipe 31 is annular, and the circulation pump 33 is provided at the inlet end of the circulation pipe 31. A plurality of heat sinks 34 are connected to the outside of the middle pipe of the circulation pipe 31. Since the compressor housing 1 is filled with lubricating oil, when the present invention is operated for a long time, its internal mechanical parts will continue to be high in temperature. At this time, the lubricating oil also reduces its cooling effect. The lubricating oil inside the compressor housing 1 is extracted by the circulation pump 33, and the lubricating oil enters the circulation pipe 31 for circulation. At this time, the circulation pipe 31 dissipates heat through the heat sink 34, and the heat sink 34 improves the heat dissipation effect.

[0055] like Figure 13As shown, a cooling fan 32 is provided in the circular ring at the end of the circulation pipe 31. The cooling fan 32 is connected to the power terminal 6 through a power line. When the cooling fan 32 is started, the cooling fan 32 cools the circulation pipe 31 by wind power, and also cools the compressor housing 1. The heat sink 34 improves the heat dissipation effect.

[0056] The use principle of the present invention:

[0057] First, the compressor mounting bracket 3 of the present invention is fixed to the working point of the existing refrigeration system to ensure stable operation of the present invention. The air inlet pipe 4 and the air outlet pipe 5 of the present invention are connected to the pipelines of the existing refrigeration system, and the power supply terminal 6 is electrically connected to the power supply of the existing refrigeration system. At this time, the compressor can be operated at any time;

[0058] During operation, the driving motor 9 drives the crankshaft 101 to rotate, and the crankshaft 101 drives the suction and pressure piston to reciprocate in the piston hole 18. Through the movement of the suction and pressure piston, the suction and pressure cylinder 171 extracts refrigerant gas from the muffler inlet pipe 174 into the suction muffler 172. After the suction muffler 172 is silenced, the refrigerant gas is input into the suction and pressure cylinder 171 through the muffler outlet pipe 173. The refrigerant gas is pressurized by the unidirectional suction and pressure of the suction and pressure cylinder 171 and then input into the metal exhaust muffler chamber 22. The metal exhaust muffler chamber 22 is silenced again to achieve a silent effect. Then, the compressed refrigerant gas is output to the existing refrigeration system pipeline through the outlet pipe 5 through the S pipe 23. When the present invention is in operation, its crankshaft 101 will guide the lubricating oil in the compressor upward. At this time, part of the lubricating oil is located at the annular groove 11. By providing the oil leakage hole 24, the oil leakage hole 24 discharges the lubricating oil downward, and at the same time, it can improve the heat dissipation of the motor.

[0059] The compressor housing 1 is filled with lubricating oil. When the present invention is operated for a long time, its internal mechanical parts will continue to be high in temperature. At this time, the lubricating oil also reduces its cooling effect. The lubricating oil inside the compressor housing 1 is extracted by the circulation pump 33, and the lubricating oil enters the circulation pipe 31 for circulation. At this time, the cooling fan 32 is started, and the cooling fan 32 cools the circulation pipe 31 by wind, and also cools the compressor housing 1. The heat sink 34 improves the heat dissipation effect.

[0060] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention are deemed to fall within the scope of protection of the present invention.
