How to adjust the fresh air air -changing machine under application?
The fans of the fresh air aircraft consent to the rated power start or lower voltage starting of the motor.When the electricity network is lacking, it should take a decompression start.When the output power exceeds 11kW, the pressure starting should be used.
When trial operation, the fan should browse the product manual carefully to check whether the connection method is in line with the same wiring method; should carefully check whether the working voltage of the supply fan switch power supply is in line with the regulations, whether the switching power supply is broken or the same as the phase,Bad, is the volume of electrical components complied with regulations.
The total number of trial running is not less than two people. One person manipulates the switch power supply, one person investigates the work of the fan, and finds that the abnormal situation is turned off immediately; you must first check whether the rotating position is appropriate. After the fan starts, it should check whether the working current is balanced.Whether the current spans the additional current; if there is an abnormal condition, it should be turned off and check it.After working for five minutes, turn off to check whether the fan is abnormal, and then start the work without abnormal situation.
When the single -speed fan is tried on, you must start with a low speed gear first, and check whether the rotating position is appropriate; when the starting speed, you must wait for the wind turbine to stop and start to prevent rotation in the direction of speed, resulting in switching and switching and motor damage.When the fan arrives at all normal speed ratios, it should be detected whether the aircraft key is normal, and the working current of the fan cannot cross its additional current.If the working current spans its additional current; it should be checked whether the working voltage of the supply fan is normal.
In the whole process of the fans in the fresh air firing machine, it is likely to cause some problems. The common faults related to the related must be quickly checked and dealt with properly to prevent the occurrence of accidents.
