Embodiment 1

[0040] Embodiment 1: a kind of filling process of refrigerant cylinder, specifically comprises the following steps:

[0041] Step 1, start up: first turn on the main power switch, turn on the cooling water circulation system, then turn on the vacuum pump and recovery compressor, and slowly open the valve of the vacuum pump and the inlet and outlet valves of the recovery machine;

[0042] Step 2, debugging: start the liquid supply pump, adjust the return valve, so that the pressure gauge is at 5.5kg / cm 2 ;

[0043] Step 3, weighing the gas cylinder: put the gas cylinder on the scale, and record the tare weight, serial number and electronic tag number of the gas cylinder;

[0044]Step 4, liquid filling: connect the liquid filling pipe, first open the vacuum valve, evacuate the liquid filling pipe for 9 seconds, then open the gas cylinder valve to evacuate the gas cylinder for 6 minutes, then close the vacuum, open the cylinder valve and pipeline liquid filling hand valve to car...

Embodiment 2

[0049] Embodiment 2: A filling process for a refrigerant gas cylinder, which differs from Embodiment 1 in that it specifically includes the following steps:

[0050] Step 1, start up: first turn on the main power switch, turn on the cooling water circulation system, then turn on the vacuum pump and recovery compressor, and slowly open the valve of the vacuum pump and the inlet and outlet valves of the recovery machine;

[0051] Step 2, debugging: start the liquid supply pump, adjust the return valve, so that the pressure gauge is at 5kg / cm 2 ;

[0052] Step 3, weighing the gas cylinder: put the gas cylinder on the scale, and record the tare weight, serial number and electronic tag number of the gas cylinder;

[0053] Step 4, liquid filling: connect the liquid filling pipe, first open the vacuum valve, evacuate the liquid filling pipe for 8 seconds, then open the gas cylinder valve to evacuate the gas cylinder for 4 minutes, then close the vacuum, open the cylinder valve and p...

Embodiment 3

[0058] Embodiment 3: a filling process of a refrigerant gas cylinder, which differs from Embodiment 1 in that it specifically includes the following steps:

[0059] Step 1, start up: first turn on the main power switch, turn on the cooling water circulation system, then turn on the vacuum pump and recovery compressor, and slowly open the valve of the vacuum pump and the inlet and outlet valves of the recovery machine;

[0060] Step 2, debugging: start the liquid supply pump, adjust the return valve, make the pressure gauge at 6kg / cm 2 ;

[0061] Step 3, weighing the gas cylinder: put the gas cylinder on the scale, and record the tare weight, serial number and electronic tag number of the gas cylinder;

[0062] Step 4, liquid filling: connect the liquid filling pipe, first open the vacuum valve, evacuate the liquid filling pipe for 10 seconds, then open the gas cylinder valve to evacuate the gas cylinder for 8 minutes, then close the vacuum, open the cylinder valve and pipelin...

Abstract

The invention discloses a filling process of a refrigerant gas cylinder, relates to the technical field of refrigerant filling, and solves the problem that a part of the refrigerant remains in the pipeline during the filling process, which causes the refrigerant to be filled multiple times. There will be a lot of waste. Connect the gas cylinder to the liquid filling pipe, first open the vacuum valve, evacuate the liquid filling pipe for 8-10s, then open the gas cylinder valve to evacuate the gas cylinder for 4-8min, then close the vacuum, open Fill the steel cylinder valve and pipeline liquid filling hand valve. After filling the liquid, close the gas cylinder valve, open the recovery valve for 8-16s, recover the remaining liquid in the liquid filling pipe, and then remove the liquid filling pipe. Repeat the above operation After filling, screw the filling tube on the bulkhead, and close all instruments and their valves. The filling process of the refrigerant gas cylinder in the present invention can recover the refrigerant remaining in the pipeline in time during the actual use process, so that a large amount of refrigerant will not be wasted when filling multiple times, and the overall performance is good. Apply effects.

Description

technical field [0001] The invention relates to the technical field of refrigerant filling, more specifically, it relates to a filling process of refrigerant cylinders. Background technique [0002] Refrigerants, also known as refrigerants, refrigerants, and refrigerants, are the medium substances used in various heat engines to complete energy conversion, and the delivery of refrigerants is mainly carried out by tank trucks, and they are filled into small packages at the subpackaging plant, and then circulated to the market, and filling operations are required in the process. [0003] In the Chinese invention patent application document with the publication number CN106439481A, the refrigerant gas cylinder filling process within 1 liter is disclosed, which is carried out according to the following steps: 1) first vacuumize the gas cylinder, and then fill in a small amount of refrigerant gas to be filled Eliminate the vacuum; 2) Then evacuate the gas cylinder again, and the...
