离心风机的运用这种类型的风机设备,目前来说大多数人运用离心风机面对的问题便是风机速度不稳，形成这种状况是怎么回事呢?
The application of centrifugal fan This type of fan equipment, at present, most people use centrifugal fan to face the problem of unstable fan speed. What is the reason for this situation?
(1)四个整流二极管中的某一只要问题
(1) Any one of the four rectifier diodes has a problem
(2)电机转子与整流子之间有碳粉或碳刷本身不良等，本着先易后难的修理准则，首要丈量可调电阻，阻值随调理而有规律的变化，证明电位器是好的，再丈量可控硅也未发现问题，因为该二极管是大电流金封管，一端上螺丝紧固在电路板上，另一头用线焊接到电路板上，从电路板上拆下时，发现正负极有松动现象，再一边丈量一边摇摆，证实该二极管时好时坏。
(2) There is carbon powder or poor carbon brush between the motor rotor and commutator. Based on the repair principle of "easy before difficult", first measure the adjustable resistance. The resistance changes regularly with conditioning, proving that the potentiometer is good, and then measure the thyristor, no problem was found, because the diode is a high current metal sealed tube, with one end screwed to the circuit board, and the other end wired to the circuit board. When it is removed from the circuit board, We found that the positive and negative poles were loose, and we measured and swayed them to confirm that the diode was good or bad.
(3)可控硅出现问题的也不少，通常是击穿短路，开路，不能触发或内部接触不良等。
(3) There are also many problems with thyristor, usually due to breakdown, short circuit, open circuit, failure to trigger, or poor internal contact.
(4)可调电阻，柜式离心风机因可调电阻安装在控制面板上，运用频率非常高，时刻长了，出现接触不良的状况很普通。
(4) Adjustable resistance: cabinet type centrifugal fan is installed on the control panel with adjustable resistance, so the application frequency is very high and the time is long. It is common that poor contact occurs.
大家在操作过程中假如发现风机出现了速度不稳现象，不妨以上面提及的四点作为排查方向，迅速找出原因，提高维修保养的功率,风机设备的多样化和多样性在无比很多的工业设备运用状况下一直是个问题，咱们应该在运用风机设备的时分清楚明了的认识到问题，认清多样化风机设备的实用性和重要性。离心风机的特点便是运用便捷轻松，可是并不代表运用是简略不需要认清的，形成离心风机运转速度不稳无非便是这几点因素，了解自己所运用的设备也是很重要的。
If you find that the speed of the fan is unstable during operation, you can use the four points mentioned above as a troubleshooting direction to quickly identify the cause and improve the power of maintenance. The diversity and diversity of fan equipment have always been a problem in many industrial equipment applications. We should have a clear understanding of the problem when using fan equipment, Recognize the practicality and importance of diversified wind turbine equipment. The feature of centrifugal fan is that it is convenient and easy to use, but it does not mean that the use is simple and need not be recognized. The unstable running speed of centrifugal fan is all these factors, and it is also important to know the equipment you use.
