中文使用说明：

1、运行初期由于润滑油的粘滞而有噪音和电流过高的情况，运行10一20分钟可自行消失。

2、流量大小不能通过开关阀门来调整。该风机是容积型压缩机，通过调整转速来改变流量和轴功率：关闭阀门，压力上升，风机超负荷运转，易被破坏，故通过改变转速或增设溢流管道来调整流量。

3、风机应在规定压力下进行工作。超负荷运转风机受损，特别是电机电流值要低于铭牌上的额定值，否则电机寿命降低。

4、压力表开关处于常闭状态，如需测定压力时可将压力表开关打开。罗茨风机

5、同一机型噪音也有差异，因为风机在机械室内的位置及配管情况不同会造成噪音的差异。

6、当风压超过58．8Kpa时，风机采用循环水冷却的方式降温，冷却水压力四6一294Kpa，冷却水温度不大于25℃。

7、冷却水用量，HDSR80型—HDSR125型，用水量5-8L/min,HDSR150型-HDSR300型，用水量8-13L/min.

8、风机运行时，先开冷却水，停机时，后关冷却水。

9、冬季风机长期不用时，应放掉冷却水，以免损坏风机。

English：

1、At the beginning Of running，due to the viscosity Of lubricating Oil, there will have noise and over-current situation. Its will automatically disappear after running about 10-20 minutes.

2、Flow quantity cant be adjusted by turn on/off valve.

3、This blower is a volume compressor，through regulating the speed to change the flow quantity and shaft power; Shut-off valve，pressure rise，blower is running under the overload condition and easy to be damaged. SO you shall change the speed or add a overflow tubing to adjust the flow quantity.

3、Blower shall be running under the authorised pressure. Overload running will damage the blower. Especially that the motor current value shall be lower than the rated value，or else its will reduce the motor’s life span.

4、Pressure gauge switch shall be under the normal close condition，ifyou need to measunng the pressure，you can turn on it.

5、Noise also has differences in the same model. Because the position Of blower in the mechanical room and the difference tubing condition can cause the difference in noise.

6、When the wind pressure is more than 58.8Kpa，blower uses the circulating water to cooling. Pressure of cooling water is 196-294Kpa，temperature Of cooling water shall be not more than 25 ℃。

7、Using quantity Of cooling water,HDSR80 Type一 HDSR125 Type，water consumption is 5-8L/min; HDSR150  Type -HDSR300 Type，water consumption is 8-13L/min.

8、When turn on the blower，you shall open the cooling water first; When shut off the blower, you shall close the cooling water late .

9、In winter，if you are not use the blower for a long time，you shall let out the cooling water avoid damage the blowe 。
