Pump body structure and compressor with it

Abstract

The invention provides a pump body structure and a compressing machine with the same. The pump body structure comprises air cylinders, a communication part and a control valve, wherein the air cylinders comprise the first air cylinder and the second air cylinder; the communication part comprises a high-pressure exhaust passage and a low-pressure suction passage which communicate with the first air cylinder correspondingly; and the control valve comprises a communication passage, the control valve optionally communicates with the high-pressure exhaust passage or the low-pressure suction passage through the communication passage, when the communication passage communicates with the high-pressure exhaust passage, the first air cylinder is in a normal working state, and when the communication passage communicates with the low-pressure suction passage, the first cylinder is in an idling state. The pump body structure can effectively reduce power consumption of the compressing machine and improve the practicality and the reliability of the compressing machine.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a pump body structure and a compressor having the same. Background technique [0002] Variable capacity compressors achieve the purpose of variable capacity by changing the number of cylinder blocks that inhale refrigerant. Usually, the external control pipeline introduces high-pressure refrigerant gas from the compressor discharge pipe through a solenoid valve or from the compressor. The intake pipe introduces low-pressure refrigerant gas into the sealing cavity of the sliding plate of the variable capacity cylinder, and controls whether the sliding plate is working by adjusting the pressure in the sealing cavity of the sliding plate of the variable capacity cylinder to realize the normal operation or stop of the variable capacity cylinder, thereby realizing variable capacity. Such as figure 1 As shown, the variable capacity compressor in the prior art includes a l...
