How to adjust the tunnel fan to the best status?
Tunnel ventilation fan is currently one of the most widely used ventilation and exhaust equipment in industrial production, but due to the influence of professional knowledge, many business owners often ignore it once it is installed. In fact, under different conditions of the tunnel fan, the effect can be different. Therefore, how to debug so that the tunnel fan can be in the best state is very important. 1. The fan allows full-voltage starting or step-down electric, but it should be noted that the current at full-voltage starting is about 5-7 times the rated current, and the step-down starting torque is proportional to the voltage square. When the grid capacity is insufficient, the fan should be Start with reduced voltage. 2. When the tunnel fan is commissioned, carefully read the product manual and check whether the wiring method is consistent with the wiring diagram; carefully check whether the working voltage of the power supply to the fan meets the requirements, wheth...
