When the high-pressure centrifugal fan is running, the current consumed by the motor will increase with the increase of pressure and vacuum. If the current is too high, the contactor will jump off. To prevent tripping or power saving, please increase the outlet as much as possible. The area, or the air pressure regulating valve on the suction or exhaust side device.
A. Air supply - inlet should be equipped with filter
1. In the case of pressurized air supply, the outlet temperature is normal to the ambient temperature of 10 °C due to air friction, so the iron pipe should be used more than 1M.
2. If used for water supply in water, the water depth of the high pressure fan should be less than 70% of the maximum static pressure indicated on the catalogue.
3. The total cross-sectional area of the air outlet should be greater than one-half of the cross-sectional area of the fan outlet.
B. Suction silencer can be installed at the suction-exit
The total cross-sectional area of the suction hole should be greater than one-half of the cross-sectional area of the inlet of the high-pressure fan.
