Information

  Roots blower should adjust the air volume of the blower according to the oxygen demand of the aeration tank. When abnormal phenomena such as sudden power failure occur in the fan, water and oil cooling system, measures should be taken immediately to ensure that the fan does not malfunction.

 
  When the fan is running, the operator should pay attention to observe the wind pressure, oil temperature, oil pressure, air volume, current and voltage of the fan and motor, and record it in time.
 
   If an abnormal situation cannot be eliminated, the machine should be shut down immediately.
 
   Check whether the cooling and lubrication system is unobstructed, and whether the temperature, pressure, and flow meet the requirements.

罗茨鼓风机的操作规程

一、开车前的准备与检查

  电压的波动值在380V±10%的范围,三相电源不能缺相;仪表和电器设备应处于良好状态,需接地的电器设备接地应可靠;风机与管道连接、机座螺栓等均应紧固;齿轮箱内润滑油应按规定牌号并加到油标线;启动前用手转动皮带轮2~3圈,看是否有异常现象;风机的出口阀停机状态应关闭,放空阀处于全开状态。

  二、开机运行

  打开放空阀和空气出口阀;启动电源,30秒后如无异常现象(如金属摩擦声、电流过大等),渐渐关闭放空阀,使其正常运行;正常运行时,决不能关闭出口阀,以免造成爆裂事故;如果同时开启数台风机,则应先开一台,待空载运转正常后再开另一台。空载运行正常后(30秒)再关闭放空阀。

  三、停机操作

  在停机前做好记录,记下电压、电流、风压、温度、运行时间等数据;逐步打开放空阀;按停机钮;关闭空气出口阀。

  四、对风机的巡视

  风机正常运行后一小时巡视一次,每隔2~3小时进行一次抄表记录(电压、电流、风压、温度等)。在巡视过程中,注意风机的声音是否正常,运行时不应有摩擦撞击声,如有异常,应立即停机检查。

  五、风机的保养

  做好例行保养工作,风机房应保持清洁,通风良好,机组表面无积尘和油垢;定期(每月)检查风机各连接螺栓的紧固程度;初次运行或大修后,风机在运行48小时后应将油箱内的润滑油全部换掉,一般连续工作500小时以上时换油;备用风机每周至少开机一小时,通常风机运转10小时后应与备用风机切换一次,以延长风机的使用寿命;正常情况下,风机运行500小时检查一次,2000小时小修一次,3000小时中修一次,15000小时大修一次。
