Inspection method of plastic fan

1. The shape standard must conform to the drawing standard.

2. The planning of the plastic fan housing and legs should ensure satisfactory strength and rigidity. When the external force and external torque of the interface flange reach the allowable value, it should not affect the normal operation of the high-pressure fan.

3. The type of connection structure between the impeller and the shaft protects the balance of the rotor from changing at high working speeds until the trip speed.

4. The noise at 1 meter from the main body of the fan shall not meet the low noise standard requirements of the use address.

5. The motor equipped with plastic fan should meet the requirements.

6. When the power grid is short-circuited and the power loss does not exceed 0.5 seconds, the fan motor function immediately returns to normal, and the motor can work continuously under full load.

7. When the fan motor is working normally, when the voltage drops to 85% and the voltage is unstable for 20 seconds, it can work continuously at the rated power without overtemperature.

Plastic fans are widely used in the exhaust of corrosive acid and alkali gases in industrial plants, the exhaust of supporting chemical laboratory equipment, the ventilation of biological laboratories, the exhaust of deodorization and purification equipment, and the exhaust of humid and corrosive areas in coastal areas.

The application environment of the plastic fan should always be kept clean and the appearance should be kept clean. Import and export without debris, plastic fan, pipe dust should be regularly removed. Plastic fans can only operate under completely normal conditions. At the same time, it should be ensured that the capacity of the power supply equipment is sufficient, the voltage is stable, and the defective operation is prohibited. The power supply line must be a special line, and the temporary line shall not be used for a long time.
