Xining in Qinghai electric damper for SWF and blower

Qinghai should reach fans hotline: 0971-8149731 18,997,216,111 18,997,216,222 13,997,124,405 13,519,703,458, Qinghai SWF blower fan is between a new axial and centrifugal fan between having a high pressure centrifugal fans, axial fans big flow, high efficiency, energy saving, low noise, easy installation and so on. Xining SWF when the blower fan design Ying, compact structure, small size, light weight, easy to install, compared with the old-fashioned centrifugal fans can save 20% speed is less than 2000r / min, the noise is less than 75dB (A), Qinghai When SWF blower installed in the connecting pipeline and air conditioning inside, noise is less than 70dB (A). You can replace 2000pa below, the low-pressure centrifugal fan, widely used in industrial, civil ventilation and dust removal. Xining main SWF blower impeller, housing, import collector, deflector, electric motors and other components. Meridian impeller has accelerated features twisted flat welded on wheels. Qinghai SWF blower by balancing check, speed test, a good aerodynamic performance. Circular enclosure, functional style is coupled into a whole set. Xining SWF blower outlet is equipped with deflector, has a good flow distribution, pressure is stable. Xining electric damper material is divided into: carbon steel, galvanized sheet. Electric fire damper is installed in the ventilation and air conditioning system, the air return duct, usually was turned on, when the fire shut down the pipeline when the flue gas temperature reaches 70 degrees. Xining electric fire damper is installed in the ventilation and air conditioning system, the return air duct, usually was turned on when the fire when the smoke pipe, close the temperature reached 70 degrees, and in a certain amount of time to meet and smoke leakage fire integrity requirements, since the role of smoke fire retardant. Qinghai electric damper usually in a normally open state, when the airflow temperature reaches 70 ℃, the temperature sensor operation, the valve closes, the valve can be closed by power; low air leakage Xining electric dampers, airtight performance, power consumption current open small, strong corrosion resistance, long life, flexible actuator drive. Feedback, interlock signal accurate. Qinghai electric damper for a room to prevent fire and smoke after the fire through the pipeline collusion to another room. Xining electric fire damper is installed in the exhaust pipe, smoke damper usually closed, after the room exhaust fan fire started, but smoke damper open, smoke room for the fire to reach the person can not escape in time when smoke damage, the fire is too large, the flame will enter the exhaust pipe through the air vents, this time 280 ° smoke damper on the fusible rod blows, smoke damper closed, exhaust fan and gives a signal to close.
