Problems solved by technology

The existing oil return control method cannot perform proper oil return according to the actual lubricating oil storage inside the compressor. There may be problems that the oil return is not turned on when the compressor is short of oil, resulting in abnormal wear or even burning of the compressor.

Embodiment 2

[0072] Such as image 3 As shown, the main structure of the compressor in this embodiment is the same as that in Embodiment 1. The lower space of the stator 6 is attached to the inner surface of the housing 11, and a liquid level sensor 35 can be installed axially, which is connected to the Data acquisition center, and pre-calibrate the minimum oil level position W4, the liquid level sensor 35 can directly measure the oil level height, if the oil level is above the minimum oil level, no oil return control is required; if the oil level reaches the minimum oil level or below, turn on the oil return control to ensure that the compressor always has enough lubricating oil. The liquid level sensor 35 can be fixed on the inner wall of the housing 11 by means of spot welding, etc., and the data line passing through the housing 11 is fixed with the housing by means of glass surrounding the data line, etc., and realizes the sealing at this place.

Abstract

The invention discloses a compressor and a heat pump system. The compressor is suitable for being applied to the heat pump system; the heat pump system is provided with an oil return device connected with the compressor and a control device used for controlling the oil return device; the compressor is provided with a detection part used for detecting the height of the oil level in a cavity, and the control device is suitable for being electrically connected with the detection part so as to control oil return according to a detection result. According to the compressor in the embodiment of the invention, the detection part capable of detecting the oil level in the compressor is arranged, therefore, the purpose of controlling oil return according to the detection result of the detection part is achieved, it is guaranteed that the compressor always has sufficient lubricating oil, and the condition of abnormal wear or compressor burning caused by oil shortage is avoided.

Description

technical field [0001] The invention relates to the field of refrigeration and heating equipment, in particular to a compressor and a heat pump system Background technique [0002] Scroll compressors are widely used in systems such as air conditioners and heat pumps because of their high efficiency, small size, light weight, and smooth operation. In the scroll compressor, a series of crescent-shaped compression chambers are formed by the meshing of the movable scroll and the fixed scroll. With the eccentric operation of the movable scroll, the crescent-shaped compression chambers Move towards the center. As a result, the refrigerant in the chamber is pushed to the center, its volume decreases continuously and the pressure rises continuously until it communicates with the central exhaust hole, the refrigerant becomes high-pressure gas and is discharged from the compression chamber to complete the compression process. [0003] During the operation of the scroll compressor, l...
