Knowledge of Roots fans
Roots FansAfter purchasing back, in order to ensure that the Roots fan better service for everyone, I think you should understand the relevant knowledge points of the Roots fan.
1, check the voltage, because the voltage is too low when starting is easy to cause damage to the Roots fan
2, fan in the trial, should carefully read the product specification, check the wiring method is consistent with the wiring diagram; should be carefully checked to supply the fan power supply voltage is not in line with the requirements of the power supply is not the lack of phase or the same phase, the capacity of the electrical components are in line with the requirements.
3, Roots fan trial number of not less than two people, a person to control the power supply, a person to observe the fan running, found anomalies immediately shut down to check; first check whether the direction of rotation is correct; fan began to run, you should immediately check the phase of the running current is balanced, whether the current is more than the rated current; if there is anomalous phenomenon, should be shut down to check. After five minutes of operation, stop the machine to check whether there is any abnormal phenomenon of the fan, confirm that there is no abnormal phenomenon and then start the operation.
4, Roots fan test run to empty running for a period of time to determine the operation of the normal, in the pressurized operation, pay attention to the observation of the fan's operating state, if the state is not right timely shutdown to check!
5, when the Roots fan reaches the normal speed, should measure the fan input current is normal, fan running current can not exceed its rated current. If the running current exceeds its rated current, the voltage supplied should be checked to see if it is normal.
