When entering the debugging after installation, you should first check whether the voltage of the power supply is within the specified range, otherwise, the voltage should be adjusted and the voltage should be adjusted.
2.Check the ventilator well.
3.Before the fan trial operation, click the power supply to check whether the direction of the fixed signs fixed with the case outside the case is consistent, otherwise the power supply phase should be adjusted.
4.In order to ensure that the fan is running according to the performance curve, the fan is not allowed to have any obstacles and ensure that the entry (out of) is unblocked. Otherwise, the blocking (out) is blocked to reduce the air volume, and even seriously causes asthma.
5.During debugging, check whether the three -phase current is balanced.Pay attention to whether the motor, impeller, drive parts, etc. have an abnormal noise at any time.Once abnormalities are found, the reasons should be disclosed immediately to stop the operation of power.
6.All fan impeller has strictly balanced correction according to the standard before leaving the factory, and the balance accuracy meets ISO-G.8 level standards.All the wind turbines have been performed before the factory is out of the factory, and the vibration speed of the whole machine meets the regulations of JB/T8689.If the wind turbine finds a severe vibration when debugging or running, it should be stopped to check the reason. The reason is found and the reasons are eliminated before it can continue to run.
7.All fans produced by the company are tested or tested in accordance with the requirements of the GB/T1236 "Test Method of Ventilation Machine Air Power Performance".If the air volume is discovered, you should first check whether the fan selection type is appropriate, and then check the resistance of the ventilation system.wait.
8.When the fan starts, the current can reach several times the rated current in an instant, so it must be prevented before startup.This series of explosion -proof roof fan is similar to a bearing fans, and should be started at a lighter load.After running normally, the load is gradually increased to avoid burning the motor.
9.When trial operation and normal operation, the temperature of the motor bearing should be checked in time.In an environment with the ambient temperature less than 50 ° C, the bearing temperature is generally not allowed to exceed 40 ° C, otherwise, it should be stopped to check.
