Note for commissioning and installation of high-temperature centrifugal fan

When the high temperature centrifugal fan reaches the normal speed, measure whether the input current of the fan is normal, and the operating current should not exceed its rated current. If the operating current exceeds its rated current, check whether the supplied voltage is normal. The debugging of high temperature centrifugal fan is not good, and the operating condition can not enter the state. According to the correct method, the efficiency can reach the standard. When the centrifugal fan is in test, the product manual should be read carefully to check whether the wiring method is the same with the wiring diagram; whether the working voltage of the fan power supply meets the requirements, whether the power supply is missing or in the same phase, and whether the capacity of the electrical components meets the requirements. During the commissioning, there shall be no less than two people, one shall control the power, observe the operation of the fan, immediately stop for abnormal phenomenon; first check whether the rotation direction is correct; after the high temperature centrifugal fan starts running, immediately check whether the operating current is balanced and whether the current exceeds the rated current; if there is abnormal phenomenon, should stop for check. After five minutes of operation, stop to check whether the fan has any abnormal phenomenon, and confirm that there is no abnormal phenomenon and start up again.
