壓縮機內部已封入了0.025~0.05MPa(表壓)的干燥氮氣,使用時應先拔掉高壓側(排氣管)的橡膠塞,否則冷凍油會噴出壓縮機。
Compressor is charged with 0.025~0.05MPa dry nitrogen , remove high pressure side (discharge tube
side) rubber plug first before application, otherwise refrigerant oil will gush from the compressor.
不得有水濺入壓縮機內。
The compressor should not be splashed with water inside.
壓縮機不得在空氣中持續打開15 分鐘以上。
The compressor should not be left open in the atmosphere for more than 15 minutes.
壓縮機不得自身抽真空及空運轉,系統抽真空應保證抽到絕對壓力為133Pa以下
The compressor should not be operated to form a vacuum and to absorb air; the evacuation of the
system shall ensure that absolute pressure is below 133Pa..
當壓縮機處于真空狀態下,不應向密封接線柱上加電脈沖。
The electric pulse should not be applied to the hermetic terminals when the compressor is under
vacuum.
壓縮機與配管,配管與配管之間的焊接應注意決不能讓焊藥、灰塵等雜質進入制冷系統。
Take care that the foreign matters like solder, dust, etc will not get into the refrigerating system from
soldering/welding joints between compressor and piping, as well as between piping.
只使用規定的制冷劑,制冷劑應從制冷系統冷凝器的尾端注入,而不能直接注入壓縮機,當制冷劑量超出規定值時,應同我公司聯系
Use only the is specified refrigerant. Refrigerant should be charged from the end of the condenser of therefrigerating systems. Never charge refrigerant to the compressor directly. When the charge amountexceeds designated value, contact us.
在壓縮機穩定運行時,系統內溫度不應低于-35℃,以防止油中蠟的成分沉淀。
Temperature within systems during stable compressor operation should not be less than -35℃ toprevent the wax in the oil from precipitation.
壓縮機起動運行前應確保接線正確,每兩次起動應間隔3 分鐘以上,絕對禁止壓縮機反向運轉和在空氣中運行。
Make sure that wiring is correct before starting the compressor, the duration between two start-ups shall exceed three minutes, it is forbidden to run compressor in reverse direction and in the air.
在裝配系統時應保證系統潔凈,為防止毛細管等堵住,必須在制冷回路中裝上過濾器。
Keep the system clean during assembly, the filter shall be assembled into the refrigerating loop to
prevent block up of capillary tube etc.
壓縮機已裝入了規定的適量冷凍油,使用時不得增加或減少。
Do not reduce or increase the refrigerant oil during application as the compressor has been charged with specified amount of oil.
為保證制冷系統的油流回壓縮機,在設計管路時氣體的最小速度,水平管內為4m/s,豎直管內為7m/s。
To ensure the oil inside the refrigerating system returns to compressor, when designing the piping, the
minimum gas velocity is 4m/s for horizontal pipe,and is 7m/s for vertical pipe.
