Title:
PUMP ASSEMBLY AND ENTHALPY-INCREASING ROTOR COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/097898
Kind Code:
A1
Abstract:
A pump assembly and an enthalpy-increasing rotor compressor, the pump assembly comprising a cylinder (100), an integrated rotating shaft (200), a first bearing, a second bearing and a combined gas replenishment channel. The combined gas replenishment channel comprises a gas introduction hole (510) formed in the first bearing or the second bearing, a first gas replenishment channel formed in a sealing end face of the first bearing or the second bearing, and a second gas replenishment channel formed in an end face of an eccentric portion of the integrated rotating shaft (200). Only when the integrated rotating shaft (200) rotates to a first preset range, all parts of the combined gas replenishment channel are in communication with each other at the same time to form a passage from the gas introduction hole (510) to a compression cavity. When the integrated rotating shaft (200) rotates at other angles other than the first preset range, the combined gas replenishment channel is disconnected. The control of the communication and disconnection of the combined gas replenishment channel is achieved by means of controlling the change of the communication state of all the parts of the combined gas replenishment channel, so that start and end timings and the gas replenishment amount in a gas replenishment process are controlled, thereby improving the gas replenishment and enthalpy increase efficiency of the compressor.
