The invention discloses a pump body assembly and an enthalpy-increasing rotor compressor. The pump body assembly comprises an air cylinder, an integrated rotating shaft, a first bearing, a second bearing and a combined air supply channel, wherein the combined air supply channel comprises an air introduction hole formed in the first bearing or the second bearing, a first air supply channel formed in the sealing end face of the first bearing or the second bearing, and a second air supply channel formed in the end face of the eccentric part of the integrated rotating shaft. Only when the integrated rotating shaft rotates to a first preset range, all parts of the combined air supply channel are communicated with one another at the same time, and a channel from the air introduction hole to the compression cavity is formed. When the integrated rotating shaft rotates to other angles except the first preset range, the combined air supply channel is disconnected. The control over connection and disconnection of the combined air supply channel is achieved by controlling changes of communication states of all parts of the combined air supply channel, so that time nodes of starting and ending of the air supply process and the air supply amount are controlled, and the air supply and enthalpy increase efficiency of the compressor is improved.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a pump body assembly and an enthalpy-increasing rotor compressor. Background technique [0002] Traditional rotary compressors have been widely used in the heat pump industry. At present, when the heat pump is used at a lower ambient temperature (such as winter at higher latitudes), its startup and heating effects will be affected by the decrease in temperature. Adverse effects, the ideal heating effect cannot be achieved. Therefore, it is urgent to increase the compression ratio and improve the compression efficiency of the rotary compressor. If a two-stage or multi-stage compressor is used to increase the compression ratio, it not only increases the compressor power and energy consumption, but also makes the internal structure of the compressor more complicated and increases the manufacturing cost. [0003] In order to solve this problem, an enthalpy-increasing rotary com...
