BHB series operating principle
the impellers in the BHB-series machines are mounted directly on the motor shaft for noncontact compression entirely without friction. Maximum operational reliabilityk,even at high differential pressures,is ensured by the arrangement of the bearings outside the compression chamber.
the gas is taken in through the inlet 1,As it enters the side channel 2,the rotating impeller 3 imparts velocity to the gas in the direction of rotation.Centrifugal force in the impeller blades accelerates the gas outward and the pressure increase.Everyrotation adds kinetic energy,resulting in the further increase.Everyrotation adds kinetic energy,resulting in the further increase of the pressure along the side channel.The side channel narrow at the rotor,sweeping the gas off the impeller blades and discharging it through the outlet silencer 4 where it exits where it exits the side channel blower.
Recker High Pressure BlowerFeatures
1.Designed and improved by the latest Europe technology,molded with high strengh ADC12 aluminum alloy,processed on precision CNC machine.
2.Two-pole motor with protection calss IP and insulation F,high temperature resistant to 180°c.
3.Motor reached Europe EFF2 standard,save more electricity,and more durable.
front bearing structure makes dynamic stability.
5.the rotating parts are not in contact with the casing,no friction during operation,no internal lubrication needed.
6.All products ard strictly tested befored leaving the factory,such as no-load test,impulse winding test,frequency withstand voltage test etc.For motor.Pressure,airflow,noise test for blower.
Recker High Pressure Blower Applications
Recker High Pressure blower have two major function,blowing and indraft. Recker High Pressure are suitable for all these applications requiring considerably higher pressure that which can be achieved using centrifugal fans.
It's widely used in environmental equipment,wastewater treatment,printing industry,bulb industry,aquatic breeding,plastic welding,chemical industry,electroplating,feeding material packing,textile,and glass utensil manufacture.
