After the refrigeration system is filled with refrigerant, if it can stop and start normally, the process port of the compressor can be sealed.
制冷系統(tǒng)充灌制冷劑后，若能正常停、啟，就可以封住壓縮機(jī)的工藝口了。

Sealing the process port of the compressor should be carried out when the compressor is running, and the specific steps are as follows.
封住壓縮機(jī)的 工藝口應(yīng)在壓縮機(jī)運(yùn)轉(zhuǎn)時進(jìn)行，具體操作步驟如下。

(1) From the nozzle of the compressor to fill the refrigerant 15 cm outward, use the process pliers to seal the compressor to clamp two places, and then in
①從壓縮機(jī)充灌制冷劑的管口向外15     cm處，用封住壓縮機(jī)的工藝口鉗夾扁兩處，再在

Use pliers to cut off the outer end 10 mm from the clamping point.
夾扁處外邊一端10 mm處用鉗子截斷。

② Polish the cut off with sand, insert into the water, there should be no air bubbles, and then wipe and apply the flux.
②用砂皮打光截斷處，插入水中，應(yīng)沒有氣泡，然后揩干并涂上助焊劑。

Solder (or gas)
用焊錫(或氣焊）
