正确的匹配易胜博手机版的风机

      一般易胜博手机版风机均为离心式风机,启动时间长,启动电流大(约6~8倍额定电流),对易胜博手机版电机和易胜博手机版风机的机械冲击力很大,严重影响其使用寿命。而采用变频调速后,可以实现软起动和软制动,对易胜博手机版电机几乎不产生冲击,可大大延长机械的使用寿命。
 
 投入变频器后易胜博手机网址除尘风机可以非常平滑稳定的调整风量,运行人员可以自如的调控,易胜博手机版风机运行参数得到了改善,提高了效率。
 
   除尘设备的风量经常需要根据工艺的要求变化,在过去用挡板调节时,存在执行机构的开度与流量的关系曲线的线形问题。除尘设备部位往往由于执行机构的磨损量过大,阀门特性发生变化,出现非线形问题,致使调节过程失误,自动控制系统无法正常工作。
 
 而变频调速始终保持在线形高精度0.1~0.01HZ的范围内工作,为实现除尘设备的自动化创造优越条件。安装变频调速后,易胜博手机版风机经常工作在比原来定速时低150转/分的转速下运行,因此,大大减少了易胜博手机版风机叶轮的磨损,减少了易胜博手机版风机振动。延长易胜博手机版风机的大修周期,节省检修费用和时间。
  Fans are generally dust centrifugal fan, start a long time, starting current (about 6 to 8 times rated current), the filter dust collector fan motor and a large mechanical impact, seriously affecting their life. The use of frequency control, you can achieve the soft start and soft braking, the motor almost no impact on ESP, can significantly extend the service life of machinery.

After the bag filter fan into the inverter can be very smooth and stable adjustment of air flow, operating personnel can freely control, dust blower operating parameters have improved, increasing efficiency.

Dust removal equipment of the wind often changes according to process requirements, in the past with a plate adjustment, the implementing agency of the existence and flow of the opening curve of the linear problem. Dust removal equipment parts often due to excessive wear of the actuator, the valve characteristic changes, presence of non-linear problem, resulting in the adjustment process errors, automatic control system does not work.

The frequency control is always maintained high-precision 0.1 ~ 0.01HZ online form within the work, dust removal equipment for the realization of automation to create favorable conditions. After the installation of frequency control, filter fans often work in low than when the original constant speed 150 rev / min speed run, therefore, greatly reducing the filter fan impeller wear, reducing the dust collector fan vibration. Extend the filter fan overhaul cycle, saving maintenance cost and time.
