讓離心風機廠傢給大傢分享一些常用調試方法

離心風機是一臺構造復雜的設備，主要有進風口，風閥，葉輪，電機、出風口組成。在不同的狀態下，離心風機的效果也不相同。因此，不同的部分運行狀況不同意，離心風機的效果會受到影響。所以要將離心風機調試至最佳狀態，可以從多個方面入手，接下來讓離心風機廠傢給大傢分享一些常用調試方法.
Centrifugal fan is a complex equipment, mainly composed of air inlet, air valve, impeller, motor and air outlet. Under different conditions, the effect of centrifugal fans is also different. Therefore, different parts of the operation do not agree, the effect of centrifugal fans will be affected. Therefore, the centrifugal fan can be debugged to the best condition. It can start from many aspects. Next, let the centrifugal fan manufacturer share some common debugging methods for you.
1、離心風機答應全壓起動或降壓電動，但應留意，全壓起動時的電流約為5-7倍的額定電流，降壓起動轉矩與電壓平方成正比，當電網容量不足時，應選用降壓起動。
1, the centrifugal fan promises full pressure starting or depressurization, but it should be noted that the current of the full pressure starting is about 5-7 印花地坪times the rated current, the starting torque is proportional to the square of the voltage, and when the capacity of the power grid is insufficient, the starting of the pressure lowering should be selected.
2、離心風機在試車時，應仔細閱讀產品說明書，查看接線方法是否同接線圖相符；應仔細查看供給風機電源的作業電壓是不是符合要求，電源是否缺相或同相位，所配電器元件的容量是否符合要求。
2, when the centrifugal fan is in trial, we should read the product instructions carefully to see whether the wiring method is in accordance with the wiring diagram; it should be carefully checked whether the operating voltage of the supply fan power is in conformity with the requirements, whether the power supply is missing or the same phase, and whether the capacity of the components of the electrical appliance is in conformity with the requirements.
3、試車時人 數不少於兩人，一人操控電源，一人觀察風機工作狀況，發現異常現象當即停機查看；首要查看旋轉方向是否正確；離心風機開端工作後，應當即查看各相工作電流 是否平衡、電流是否超越額定電流；若有不正常現象，應停機查看。工作五分鐘後，停機查看風機是否有異常現象，承認無異常現象再開機工作。
3, the number of people in the test is not less than two people, one person manipulates the power supply, one person observes the working condition of the fan, and finds out the abnormal phenomenon immediately to see if the rotating direction is correct. After the centrifugal fan begins to work, it should be to see whether the current is balanced or whether the current is beyond the rated current; if there is no normal current, it is abnormal. The phenomenon should be stopped to check. After working for five minutes, stop to check if there is any abnormal phenomenon of the fan, admit that there is no abnormal phenomenon and then start the work again.
4、雙速離心風機試車時，應先起動低速，查看旋轉方向是否正確；起動高速時有必要待風機停止後再發動，以防高速反向旋轉，引起開關跳閘及電機受損。
4, when the double speed centrifugal fan is test, we should start the low speed first to see whether the rotation direction is correct; it is necessary to start at high speed when the fan is stopped, so as to prevent the high speed reverse rotation and cause the switch trip and motor damage.
5、離心風機到達正常轉速時，應丈量風機輸入電流是否正常，離心風機的工作電流不能超越其額定電流。若工作電流超越其額定電流，應查看供給的電壓是否正常。
5. When the centrifugal fan reaches the normal speed, it is necessary to measure whether the input current of the fan is normal, and the working current of the centrifugal fan can not exceed its rated current. If the working current exceeds its rated current, check whether the supply voltage is normal.
6、離心風機 所需電機功率是指在必定工況下，對離心風機和風機箱，進風口全開時所需功率較大。若進風口全開進行工作，則電機有損壞的風險。風機試車時最好將風機進口或 出口管道上的閥門封閉，工作後將閥門漸漸敞開，到達所需工況停止，並留意風機的工作電流是否超越額定電流。
6. The power required by the centrifugal fan is larger than that required for the centrifugal fan and fan box when the inlet is fully opened under certain conditions. If the intake port is fully open, the motor is at risk of damage. When the fan is in test, it is better to close the valve on the inlet or outlet pipe of the fan. After working, the valve will be opened gradually to the required condition, and whether the working current of the fan exceeds the rated current.
嚴厲依照上述調試方法對離心風機進行調試，可讓離心風機的效率到達98%以上。
According to the above debugging method, the centrifugal fan can be adjusted to make the centrifugal fan 透水地坪more efficient than 98%.
