Abstract

The present invention provides a pump body assembly, a compressor and a heat exchange system. The pump body assembly includes a main shaft, a negative pressure part, an oil pipe component, an air cylinder and a first flange, the main shaft is provided with a hollow cavity; the negative pressure is arranged on the first end of the main shaft to form a negative pressure in the hollow cavity; the oil pipe component is arranged on the second end of the main shaft, and is connected with the hollow cavity of the main shaft; the first flange and the air cylinder are stacked along the axial direction of the main shaft, the end surface of one side, toward the air cylinder, of the first flange is provided with a lubricating oil groove, and the hollow cavity of the main shaft is communicated with the lubricating oil groove. The negative pressure part is arranged at the end of the main shaft, when the negative pressure part works, the negative pressure can be formed in the hollow cavity of the main shaft, so that oil in an oil tank of the compressor is sucked into the hollow cavity of the main shaft by the oil pipe component, and then flows to the lubricating oil groove of the first flange under effect of the centrifugal force of the hollow cavity brought by rotation of the main shaft to provide a reliable backpressure for a sliding piece in the air cylinder so as to effectively solve the problem of insufficient backpressure oil supply caused by backpressure instability.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a pump body assembly, a compressor and a heat exchange system. Background technique [0002] The back pressure of the vane compressor in the prior art is supplied by the oil channel on the lower flange, and the power supply for the movement of the vane is provided by the pressure difference between the oil pool and the tail of the vane groove. Unstability, so that the pump body assembly has the problem of poor back pressure reliability, resulting in poor followability of the sliding vane, and even leakage of the front and rear chambers of the sliding vane. [0003] For a better explanation, please refer to Figure 1 to Figure 3 A specific embodiment of a vane compressor is shown. [0004] Such as Figure 1 to Figure 3 The compressor shown includes a housing 10', a main shaft 20', a cylinder 30', an upper flange 40' and a lower flange 50', and its back pressure oil is suppl...
