压缩机内部已封入了0.025~0.05MPa(表压)的干燥氮气,使用时应先拔掉高压侧(排气管)的橡胶塞,否则冷冻油会喷出压缩机。
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.
不得有水溅入压缩机内。
The compressor should not be splashed with water inside.
压缩机不得在空气中持续打开15 分钟以上。
The compressor should not be left open in the atmosphere for more than 15 minutes.
压缩机不得自身抽真空及空运转,系统抽真空应保证抽到绝对压力为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..
当压缩机处于真空状态下,不应向密封接线柱上加电脉冲。
The electric pulse should not be applied to the hermetic terminals when the compressor is under
vacuum.
压缩机与配管,配管与配管之间的焊接应注意决不能让焊药、灰尘等杂质进入制冷系统。
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.
只使用规定的制冷剂,制冷剂应从制冷系统冷凝器的尾端注入,而不能直接注入压缩机,当制冷剂量超出规定值时,应同我公司联系
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.
在压缩机稳定运行时,系统内温度不应低于-35℃,以防止油中蜡的成分沉淀。
Temperature within systems during stable compressor operation should not be less than -35℃ toprevent the wax in the oil from precipitation.
压缩机起动运行前应确保接线正确,每两次起动应间隔3 分钟以上,绝对禁止压缩机反向运转和在空气中运行。
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.
在装配系统时应保证系统洁净,为防止毛细管等堵住,必须在制冷回路中装上过滤器。
Keep the system clean during assembly, the filter shall be assembled into the refrigerating loop to
prevent block up of capillary tube etc.
压缩机已装入了规定的适量冷冻油,使用时不得增加或减少。
Do not reduce or increase the refrigerant oil during application as the compressor has been charged with specified amount of oil.
为保证制冷系统的油流回压缩机,在设计管路时气体的最小速度,水平管内为4m/s,竖直管内为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.
