介紹酒店冷庫的氣密性測量方法
Introduce hotel refrigerator air-tightness measuring method
1、首先將排氣截止閥桿順時針選到底，食品冷庫使系統在壓縮機的排氣口失去循環通道。
1, first of all, the selection of the exhaust valve lever clockwise to the end, make the system in the compressor vent lost circulation channel.
2、逆時針旋下排氣截止閥多用通道的細牙螺塞，使排氣口與大氣相通。
2, unscrew the exhaust valve counterclockwise multi-purpose channel of fine thread plug, vent and atmosphere are interlinked.
3、打通系統內的所有閥門。
3, get through all valves in the system.
4、短接低壓繼電器的觸點，臨時性撤去保護功能（事后必須復原）。
4, short answer the under-voltage relay contact, temporary removed protection function (must recover later).
5、啟動壓縮機，使系統內的空氣排入大氣（壓縮機的吸氣閥門應緩慢打開，以免系統內的氣體來不及排出，造成排氣壓力過高而引起高壓保護等）。
5, start the compressor, make the atmosphere of air inside the system (compressor suction valve should be opened slowly, in order to avoid the system enough time of gas discharge, high exhaust pressure caused by the high voltage protection, etc.).
6、觀察低壓端的真空表，直至真空壓力表的讀數達到--0.1MPa，適當時間后將排氣截止閥桿旋轉退出并旋緊。
6, observing the low voltage side vacuum gauge until the vacuum pressure gauge readings to -- 0.1 MPa, the appropriate time will exhaust valve rod rotation exit and tighten.
