When cold water machine starts to the attention of

(1)低温冷水机转动联轴器2-3圈，比较好移动，不应过紧。

(1) low temperature cold water machine rotation coupling 2-3 ring, good move, should not be too tight.

(2)接通电源开启冷水机，同时要打开制冷机的排气阀。

(2) power on opening the cold water machine, at the same time, the exhaust valve to open the refrigerator.

(3)当电动机开始运转后应调整油压。

(3) when the motor starts to run after the adjustment of oil pressure.

(4)级当制冷机启动后，开启吸气阀时，若听到液击声侧要立即关闭后关小吸气阀门，待液击声消除后 再级慢打开。

(4) level when after the start of the refrigerator, open the suction valve, if heard, liquid hammer sound side to immediately after the closure of small suction valve closed, stay liquid hammer sound eliminated after the level is slow to open.

(5)能量调节阁应在负荷需要逐级调节，一般应每隔2-3min拨一挡，并注意每援一挡时要看油压有无变化。

(5) ge energy regulation should be adjusted in the load need step by step, the general should be every 2-3min dial a block, a block and each aid to see there is no change in pressure.

(6)排气压力不得高于1.6MPa。工作电流应符合顺定值.当电流读数剧烈上升时应立即停机检查，排除故津后再重新启动。

(6) the exhaust pressure shall not be higher than 1.6MPa. The current work should be consistent with the CIS constant. When the current rises sharply when reading should stop immediately check and eliminate it and restart the tianjin.

(7)根据高压贮液器的液面及制冷压缩机的负荷情况，开启调节站的有关澎胀阀向氮液分离器或低压贮液捅供液。当低压循环楠的液面高于50%时.应先开氮泵再开制冷压络机。

(7) according to the load condition of the liquid level of high pressure liquid storage and refrigeration compressor, open the regulatory site of the Peng expansion valve to poke a liquid nitrogen separator or low pressure liquid storage for liquid. When the liquid level low pressure circulation Nan is higher than 50%. Nitrogen pump should be open open refrigeration pressure winding machine.

(8)填写冷水机的工作运转日记。记录开机时间和制冷压缩机的吸、排气沮度和吸、排气压力.油压、轴封沮度，冷凝器进、出水沮度及其他运行情况。

(8) the operation of the chiller to fill in the diary. Boot record time and refrigeration compressor suction, exhaust Ju and ceiling, exhaust pressure. Pressure, shaft seal Ju, into the condenser, the effluent Ju and other operating conditions.
