Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration compressors, in particular to a compensator used for oil return of a compressor. Background Art

[0002] A compressor is a device used to compress and increase the pressure of a gas (such as air, nitrogen, hydrogen, etc.) or a gas mixture. The compressor mainly increases the pressure of the gas by reducing the volume of the gas so that it can meet specific industrial or production needs. Compressors are generally widely used in refrigeration, air conditioning, air compressors, chemical industry, petrochemical industry, energy and other fields. In a compressor, the compensator is an important component used to adjust the working state of the compressor. Its main function is to maintain the high efficiency and stable operation of the compressor under different working conditions.

[0003] Most of the compensators in existing compressors are straight-through compensators, which have poor oil return effects and lead to defects in the oil level of the compressor. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a compensator for oil return of a compressor, aiming to improve the problem that the oil return effect of the existing compensator is poor, resulting in defects in the oil level of the compressor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compensator for compressor oil return, comprising a shell, three hanging plates are fixedly connected to the upper part of the outer wall of the shell, a hanging hole is opened on one end surface of the hanging plate, a vent pipe is provided on the upper end surface of the shell, an oil supply port is fixedly connected to the left side of the lower part of the outer wall of the shell, and an oil unloading port is fixedly connected to the right side of the lower part of the outer wall of the shell.

[0006] Preferably, the three hanging plates are evenly distributed along the central axis of the shell.

[0007] Preferably, the length of the sub-oil supply port is shorter than the length of the hanging plate, and the length of the oil unloading port is equal to the length of the sub-oil supply port.

[0008] Preferably, the oil supply port and the oil discharge port have the same inner diameter.

[0009] Preferably, the ventilation pipe is arranged above the central axis of the shell.

[0010] Preferably, the oil supply port and the oil unloading port are at the same height.

[0011] The utility model has the following beneficial effects:

[0012] 1. In the utility model, by setting the vent pipe, the oil distribution port and the oil discharge port, since the height of the oil distribution port and the oil discharge port are consistent, gas is introduced into the interior of the compensator. According to the communicating vessel principle, the storage oil amount of the compressor can be increased. When the oil amount is too much, the excess oil can be released through the oil discharge port. On the contrary, when the oil amount is too low, the oil distribution port is used to supply the compressor with oil, so that the oil amount of the compressor is always kept within a normal range, which can provide guarantee for the stable operation of the compressor.

[0018] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-Figure 3The utility model provides an embodiment: a compensator for compressor oil return, comprising a shell 1, three hanging plates 3 are fixedly connected to the upper part of the outer wall of the shell 1, and the three hanging plates 3 are evenly distributed along the central axis of the shell 1. A hanging hole 4 is opened on one end surface of the hanging plate 3, and the hanging hole 4 on the hanging plate 3 provides an installation position for facilitating the connection of the compensator to the inside of the compressor; a vent pipe 2 is provided on the upper end surface of the shell 1, and the vent pipe 2 is arranged above the central axis of the shell 1. The vent pipe 2 is an external thread pipe mouth and is connected to the crankcase ventilation to provide gas for the inside of the compensator, and a sub-oil supply port 5 is fixedly connected to the left side of the lower part of the outer wall of the shell 1, and an oil unloading port 6 is fixedly connected to the right side of the lower part of the outer wall of the shell 1, and the oil unloading port 6 is connected to the oil cavity of the compressor, and the oil unloading port 6 is horizontal to the oil bottom surface of the compressor, and the sub-oil supply port 5 and the oil unloading port 6 are at the same height, and the inner diameter of the sub-oil supply port 5 and the oil unloading port 6 are the same, and the length of the sub-oil supply port 5 is shorter than the length of the hanging plate 3, and the length of the oil unloading port 6 is equal to the length of the sub-oil supply port 5.

[0020] Specifically, by utilizing the connecting device principle, gas is introduced into the interior of the compensator through the ventilation pipe 2. When the oil level is too high, the excess oil can be released through the oil unloading port 6. When the oil level is too low, the oil can be added to the compressor through the oil supply port 5. This setting can keep the oil level inside the compressor within a normal range.

[0021] Working principle: through the communicating vessel principle, since the oil unloading port 6 and the oil distribution port 5 are maintained at the same height, the gas entering through the vent pipe 2 can keep the oil volume in a balanced state. During the operation of the compressor, if the oil volume is too high, the excess oil can be discharged through the oil unloading port 6. Conversely, when the oil volume is too low, oil can be supplied to the inside through the oil distribution port 5, so that the oil volume inside the compensator reaches a balanced state.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
