During Multifunctional coolant machine work of the present invention, need coordinate the high-low pressure table to carry out work.
The workflow of this Multifunctional coolant machine is carried out in the steps below:
A. reclaim refrigerant: in order to prevent from the air-conditioning maintenance machine reclaiming refrigerant, air in pipeline is sneaked in refrigerant, at first the first extension tube attached 17 on casing is connected with the common port of high-low pressure table, make the low-pressure end of high-low pressure table be connected with the low-voltage interface of motorcar air conditioner, the high-pressure side of high-low pressure table is connected with the high voltage interface of air conditioning for automobiles again.Close low pressure valve and high pressure valve on the high-low pressure table, then press the vacuumizing start button, exhaust solenoid valve 6 is opened, and opens and vacuumizes hand valve 12, and compressor 1 running vacuumizes, compressor 1 and the air exhausting that reclaims input magnetic valve 2, vacuumize in hand valve 12 these two segment pipes are removed, after emptying 1-2 minute, press immediately and vacuumize stop button, exhaust solenoid valve 6 is closed, turn off and vacuumize hand valve 12, stopping compressor 1(a step purpose is to guarantee to reclaim refrigerant not containing air).
B. open the height pressure valve on the high-low pressure table, press the refrigerant recovering start button, reclaim input magnetic valve 2 and reclaim output solenoid valve 3 and open simultaneously, compressor 1 starts running, under the acting in conjunction of the suction produced in the pressure of refrigerant itself and compressor 1 running, the refrigerant in the motorcar air conditioner refrigeration system is smoothly through high-low pressure table, the first extension tube attached 17 input refrigerant workover rig.Refrigerant, through filter 16, recovery input magnetic valve 2, the first check valve 24, separator 10, compressor 1, recovery output solenoid valve 3, the second check valve 23, condenser, reservoir 15, finally is recovered and is stored in reservoir 15.After refrigerant recovering, close the low pressure valve of high-low pressure table, press the refrigerant recovering stop button, compressor 1 quits work, reclaim input magnetic valve 2 and reclaim output solenoid valve 3 and close simultaneously, meanwhile return-air magnetic valve 5 and oil drain solenoid valve 25 are opened simultaneously, compressor 1 high-pressure side gases at high pressure cooled via return air magnetic valve 5 input separators 10, by oil drain solenoid valve 25, the waste oil of separator 10 bottoms is discharged to together and connects oil bottle 26.
C. motorcar air conditioner pressurization leak detection: the high pressure valve of opening the high-low pressure table, press pressurization leak detection start button, pressurization input magnetic valve 4 and pressurization output solenoid valve 7 are opened simultaneously, open pressurization hand valve 13, air enters compressor 1 through pressurization input magnetic valve 4, be compressed into gases at high pressure by compressor 1, gases at high pressure, through pressurization output solenoid valve 7, the 3rd check valve 22, pressurization hand valve 13, finally in the first extension tube attached 17, high-low pressure table input automobile air conditioner system, are realized the pressurization leak detection function to refrigeration system.The pressurization leak detection is complete, turns off the high pressure valve of pressurization hand valve 13 and high-low pressure table, presses pressurization leak detection stop button, and compressor 1 shuts down, and pressurization input magnetic valve 4 and pressurization output solenoid valve 7 are closed simultaneously.
D. automobile air conditioner system vacuumizes: press the vacuumizing start button, exhaust solenoid valve 6 is opened, open the height pressure valve that vacuumizes hand valve 12 and high-low pressure table, start compressor 1, air in air-conditioning system through high-low pressure table, the first extension tube attached 17, vacuumize hand valve 12, compressor 1, exhaust solenoid valve 6 and discharge, observe the reading of high-low pressure table, when the demonstration of high-low pressure table enters negative pressure, press and vacuumize stop button, exhaust solenoid valve 6 is closed, turn off again the height pressure valve that vacuumizes hand valve 12 and high-low pressure table, stop compressor 1.
E. the Multifunctional coolant machine fills refrigerant; At first start automobile and open air-conditioning, open the low pressure valve that fills hand valve 14 and high-low pressure table, under the acting in conjunction of the pressure of refrigerant itself and the formed suction of automobile air conditioner system vacuum, refrigerant is inhaled in automobile air conditioner system, annotate after suitable coolant quantity, close the low pressure valve that fills hand valve 14 and high-low pressure table, the whole course of work finishes.
Embodiment 2, as shown in Figure 2, the unique distinctive points of embodiment 2 and described embodiment 1 is: also be provided with stop valve 28 on described the first extension tube attached, stop valve is the same with the effect of above-mentioned high-low pressure table, can play and be communicated with or disconnection automobile air conditioner system and Multifunctional coolant machine system.
