Problems solved by technology

[0002] The fan speed of the oil supply assembly of the existing rolling rotor compressor is the same as the crankshaft rotation speed of the compressor, and the oil supply is limited by the crankshaft speed. There is a demand for the compressor to operate at an ultra-low speed in the market, such as considering the heat management of the whole vehicle The air conditioner of new energy vehicles, under certain conditions of some models, only needs to cool down the power battery, the required cooling capacity is very low, which is very different from the required cooling cap

Example Embodiment

[0039] In order to make the objects, technical solutions, and advantages of the present invention, the technical solutions of the present invention will be described in conjunction with the specific embodiments and appended claims. Obviously, the described embodiments are merely embodiments of the invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.

[0040] Combine Figure 1 to 8 As shown, the present invention provides a fuel supply assembly, and the oil supply assembly 10 includes a fan 12, and the fan 12 is configured to be capable of adjusting the pressure differential of the crankshaft center oil hole 212 of the crankshaft 21 according to the real-time speed of the compressor motor 30. Make the crankshaft center oil hole 212 to operate normally during the compressor motor 30.

Abstract

The invention provides an oil supply assembly, a compressor and a control method. The oil supply assembly comprises a fan, and the fan is configured to adjust the pressure difference between the two ends of a crankshaft center oil hole according to the real-time rotating speed of a compressor motor so that the crankshaft center oil hole can be normally oiled when the compressor motor runs. The technical problems that the rotating speed of a fan of an oil supply assembly of a compressor is consistent with the rotating speed of a crankshaft of the compressor, the oil supply amount is limited by the rotating speed of a crankshaft, and consequently oil supply is not smooth during operation of the compressor are solved, the rotating speed range of the compressor motor is widened, and on the other hand, the oil spitting rate of the compressor can be reduced.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an oil supply assembly, a compressor and a control method. Background technique [0002] The fan speed of the oil supply assembly of the existing rolling rotor compressor is the same as the crankshaft rotation speed of the compressor, and the oil supply is limited by the crankshaft speed. There is a demand for the compressor to operate at an ultra-low speed in the market, such as considering the heat management of the whole vehicle The air conditioner of new energy vehicles, under certain conditions of some models, only needs to cool down the power battery, the required cooling capacity is very low, which is very different from the required cooling capacity when running at full load. At this time, the working speed of the compressor motor even only It needs 5rps. The minimum working speed of the existing compressor motor generally requires more than 10rps. If it i...
