1380*1380*370 suction air ventilation fan

1380*1380*370 suction air ventilation fan use of foreign advanced technology for the production of F class insulation fan special aluminum shell motor. With under phase overload protection, long service life, stable operation, low noise.

Animal husbandry and fan of negative pressure fan

Animal husbandry is also known as negative pressure fan, fan is the latest type of ventilation fans, belong to the axial flow fan, because is mainly used in negative pressure ventilation cooling engineering while the negative pressure fan. Negative pressure ventilation cooling engineering contains the meaning of the two aspects of ventilation and cooling, ventilation and cooling problems at the same time. Suction fan is also applied to the positive pressure type water environmental protection air conditioning, the positive pressure air supply, the positive pressure blower, etc. Negative pressure fan has a huge volume, large air duct, ultra strong wind leaf diameter, large exhaust air volume, low energy consumption, low speed, low noise, etc.

1).ABOUT US

Qingdao Peng Sheng Electrical appliance CO.,LTD. Located in the cultural historical seaside famous city -- Jimo ,which predecessor is the Qingdao Hong Sheng Electrical Appliance factory(founded in 1998),in 2012 according to the international technical standards and combination with QingDao Hongxing Electrical Appliance Factory technology, established the QingDao Peng Sheng Electrical Appliance CO., LTD. Focus on ventilation fan more than 20 years.

2).OUR PRODUCT

A famous company specializing in the production of air blower, exhaust fan, axial fan, centrifugal fan, the enterprise of science and technology of ventilation equipment, about 20years has been committed to developing of science and technology products.

Some question and solution:

1. supply voltage is too low, negative pressure fan start or run, produce abnormal sound and vibration.

Solution: the power supply voltage is controlled within the range of rated voltage. Can usually choose the voltage regulator or power voltage regulator to stabilize the voltage.

2. negative pressure fan wind blade impact wind casing (cover).

Solution: fan blade adjustment reasons: vacuum blower fan motor bearing adverse, axial flow fan base screw loosening, wind leaf on the shaft is not fixed tightly, wind leaf apex and a hood body gap.

3. negative pressure fan base screw loose, impeller assembly is poor, the speed is too fast, fixed screw on the shaft and so on.

Solution: the negative pressure fan base, the shaft of the screw fastening. To re assemble and adjust the gap between the impeller and the impeller according to the technical requirement.
