In some embodiments, when compressor needs to shut down, second switch valve 52 and third switch valve 62 are opened, the One switch valve 42 and the 4th switch valve 72 are closed, and low-pressure fluid enters first and adjusts pipeline 2, are generated first to adjustment sheet 12 and are pushed away Power;High-pressure fluid enters second and adjusts pipeline 3, generates the second thrust to adjustment sheet 12;First thrust is less than the second thrust, thrust Official post adjustment sheet 12 resets, and adjustment sheet 12 separates venting flow path 11, and the ventilatory capacity of venting flow path 11 is zero.
In unit running process, compressor can be in different operating conditions, and the supplementing method for air of compressor making-up air device is suitable for pressure The case where compressor is in the first operating condition and the second operating condition is set forth below in the different operating conditions of contracting machine.
When running the first operating condition for unit:
1) when the rigid starting up of unit, adjustment sheet 12 is in initial position, separates venting flow path 11, venting flow path 11 it is logical Tolerance is zero.Adjustment sheet 12 is locked, prevents adjustment sheet 12 from malfunctioning.First, which adjusts pipeline 2, second, adjusts pipeline 3 in closing State does not adjust pipeline 3 to the first adjusting pipeline 2, second and is passed through gaseous coolant, can not establish pressure difference, and adjustment sheet 12 is in complete Closing shuts state, does not carry out tonifying Qi to compressor, can effectively avoid unit band and carries starting.
2) when running the first operating condition after unit booting, first switch valve 42 and the 4th switch valve 72 are opened, second is closed and opens Valve 52 and third switch valve 62 are closed, takes gaseous coolant to be passed through the first adjusting pipeline 2 from condenser 8, the first thrust F1 is generated, from sudden strain of a muscle Hair device 9 takes gaseous coolant to be passed through the second adjusting pipeline 3, generates the second thrust F2 (as shown in Figure 4), and F1 > F2,12 band of adjustment sheet Dynamic central axis 13 starts to rotate, and aperture starts to change from 0 ° to 90 ° of maximum opening of initial position.
Default initial pressure value of the flash evaporation 9 under the first operating condition is Ps01,
Wherein, Ps01Pressure value when being in the steady operational status under the first operating condition for compressor, in flash evaporation 9;
Pe01Pressure value when being in the steady operational status under the first operating condition for compressor, in evaporator;
Pc01Pressure value when being in the steady operational status under the first operating condition for compressor, in condenser 8.
Work as Psx=Ps01, i.e. pressure value P of the unit during bring into operation to stable state, in flash evaporation 9sxWith it is pre- If initial pressure value Ps01When equal, adjustment sheet 12 is rotated to an optimal aperture, at this time locks adjustment sheet 12.
First switch valve 42 and the 4th switch valve 72 are simultaneously closed off, second switch valve 52 and third switch valve 62 are constantly in Closed state.Stop to first adjusting pipeline 2 and second adjusting pipeline 3 be passed through gaseous coolant, prevent adjustment sheet 12 because differential pressure after Continuous rotation.
3) compressor emergency shutdown resets: when unit needs to shut down, second switch valve 52 and third switch valve 62 being opened, first Switch valve 42 and the 4th switch valve 72 are closed;It takes gaseous coolant to be passed through the first adjusting pipeline 2 from flash evaporation 9, takes gas from condenser 8 State refrigerant is passed through the second adjusting pipeline 3;Release the locking of adjustment sheet 12 simultaneously, gaseous coolant sets up pressure difference, adjustment sheet 12 because Thrust starts to rotate with central axis 13, and aperture starts to change for 0 ° from optimal aperture to minimum aperture, until aperture is reduced to minimum After 0 ° of aperture, then adjustment sheet 12 locked.It closes second switch valve 52 and third switch valve 62, first switch valve 42 and the 4th is opened Close valve 72 be constantly in closed state, stop to first adjusting pipeline 2 and second adjusting pipeline 3 be passed through gaseous coolant, stop to Compressor tonifying Qi.
When running the second operating condition for unit, working principle is same as above.
1) when the rigid starting up of unit, adjustment sheet 12 is in initial position, separates venting flow path 11, venting flow path 11 it is logical Tolerance is zero.Adjustment sheet 12 is locked, prevents adjustment sheet 12 from malfunctioning.First, which adjusts pipeline 2, second, adjusts pipeline 3 in closing State does not adjust pipeline 3 to the first adjusting pipeline 2, second and is passed through gaseous coolant, can not establish pressure difference, and adjustment sheet 12 is in complete Closing shuts state, does not carry out tonifying Qi to compressor, can effectively avoid unit band and carries starting.
2) when running the second operating condition after unit booting, first switch valve 42 and the 4th switch valve 72 are opened, second is closed and opens Valve 52 and third switch valve 62 are closed, takes gaseous coolant to be passed through the first adjusting pipeline 2 from condenser 8, the first thrust F1 is generated, from sudden strain of a muscle Hair device 9 takes gaseous coolant to be passed through the second adjusting pipeline 3, generates the second thrust F2 (as shown in Figure 4), and F1 > F2,12 band of adjustment sheet Dynamic central axis 13 starts to rotate, and aperture starts to change from 0 ° to 90 ° of maximum opening of initial position.
Default initial pressure value of the flash evaporation 9 under the second operating condition is Ps02,
Wherein, Ps02Pressure value when being in the steady operational status under the second operating condition for compressor, in flash evaporation 9;
Pe02Pressure value when being in the steady operational status under the second operating condition for compressor, in evaporator;
Pc02Pressure value when being in the steady operational status under the second operating condition for compressor, in condenser 8.
Work as Psx=Ps02, i.e. pressure value P of the unit during bring into operation to stable state, in flash evaporation 9sxWith it is pre- If initial pressure value Ps02When equal, adjustment sheet 12 is rotated to an optimal aperture, at this time locks adjustment sheet 12.
It closes first switch valve 42 and the 4th switch valve 72, second switch valve 52 and third switch valve 62 is constantly in closing State.Stop being passed through gaseous coolant to the first adjusting pipeline 2 and the second adjusting pipeline 3, prevents adjustment sheet 12 from continuing to revolve because of differential pressure Turn.
3) compressor emergency shutdown resets: when unit needs to shut down, second switch valve 52 and third switch valve 62 being opened, first Switch valve 42 and the 4th switch valve 72 are closed;It takes gaseous coolant to be passed through the first adjusting pipeline 2 from flash evaporation 9, takes gas from condenser 8 State refrigerant is passed through the second adjusting pipeline 3;Release the locking of adjustment sheet 12 simultaneously, gaseous coolant sets up pressure difference, adjustment sheet 12 because Thrust starts to rotate with central axis 13, and aperture starts to change for 0 ° from optimal aperture to minimum aperture, until aperture is reduced to minimum After 0 ° of aperture, then adjustment sheet 12 locked.It closes second switch valve 52 and third switch valve 62, first switch valve 42 and the 4th is opened Close valve 72 be constantly in closed state, stop to first adjusting pipeline 2 and second adjusting pipeline 3 be passed through gaseous coolant, stop to Compressor tonifying Qi.
