In order to ensure the safe operation of the high-pressure fan, the power supply should use a fixed voltage and a fixed cycle wave number. Usually, the label of the device has the corresponding recorded value, and the correct wiring is assembled according to the wiring diagram. In addition, the voltage fluctuation of the high-pressure fan must be within five percent of the fixed voltage. Ten percent can be used, but if the voltage changes for a long time, the high-pressure fan is prone to failure, please avoid using it.
Because the high-pressure fan does not have an overheating load protection device, the heat of the fan cannot be monitored frequently, so the overload protection electromagnetic switch needs to be set with the same horsepower. Also, please adjust the safe current at the same value. At the same time, the standard wiring is selected by the horsepower of the motor and the method of electrical operation.
After the wiring of the high-pressure fan is completed, turn on the switch to confirm the direction of rotation and check whether there is noise. The direction of rotation is indicated by the arrow of the blower. If the direction of rotation is incorrect, the order of sucking and supplying air is reversed. If the three-phase system is three-phase, then any two of the three external circuits can be changed.
At the same time, high-voltage enthusiasts need to be grounded in order to prevent accidents when leakage occurs. The leaf valve with metal parts of the high-pressure fan is installed on the suction port. When the pressure exceeds the set pressure value of the high-pressure fan, or when the pressure fluctuation of the high-pressure fan exceeds the set value, the pressure leaf valve immediately opens within 0.2 seconds to release the excess pressure through the air flow to protect the leaf effect of the high pressure F.
In short, pay attention to the accessories and installation details of the high-pressure fan, provide a good foundation for the safe and reliable driving of the high-pressure fan, reduce the possibility of failure, and play a better role by extending the service life of the equipment. Cement that can cope with it.
How to debug the high pressure fan to make it in a better state
1. The high-pressure fan allows full-voltage start or reduced-voltage electric, but it should be noted that the current at full-voltage start is about 5-7 times the rated current, and the reduced-voltage starting torque is proportional to the square of the voltage. When the grid capacity is insufficient, Start with reduced voltage.
2. When the high-pressure fan is being tested, read the product manual carefully to 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, whether the power supply is missing or in the same phase, and the power distribution components Whether the capacity meets the requirements.
3. During the test run, there are no less than two people. One person controls the power supply, and the other observes the operation of the high-pressure fan. If any abnormal phenomenon is found, stop and check immediately; first check whether the direction of rotation is correct. After the high-pressure fan starts to run, check whether the operating current of each phase is immediately Whether the balance and current exceed the rated current; if there is any abnormality, stop the machine for inspection. After running for five minutes, stop the machine and check whether there is any abnormality in the high-pressure fan, confirm that there is no abnormality, and start the machine.
