BK Three-lobe Roots Blower

The BK series of three-lobe Roots blowers with integrated impeller and shaft are mainly used in many industries such as environmental protection, electric power, building materials, and pneumatic conveying.

Features:

• Synchronous gear of helical gear structure adopted for stable transmission
• Compact structure, same air inlet and outlet structure for flexible installation
• Reasonable bearing structure for long service life
• Low noise, small vibration, small size, low energy consumption

Performance Data:

Compared with the BK blower, water cooling adopted for end cover bearing to increase the blower’s applicable pressure

Adopte Standard horizontal installation type, vertical installation type available if required.

Same as BK blower: integrated impeller and shaft structure, helical gears, imported bearings and oil seals.

Outlet diameter: 65~350mm

Air capacity range: 25~146.88m³/min

Applicable pressure range (discharge rising pressure): 6~1.0kgf/cm²

• Realize two-stage air compressing in one blower main body to achieve higher pressure
• water cooling adopted for housing, end cover bearing for more stable operation
• Compared with the BKD type, size is smaller.
• It runs smoothly and can be used in vehicle-mounted systems.
• Outlet diameter: 65~150mm
• Air capacity range: 2.4~40m3/min
• Applicable pressure range (discharge rising pressure): 1.0~1.5kgf/cm2
• The blower’s housing is divided into upper and lower parts, which are easy for disassembling and convenient for maintenance.
• Higher applicable pressure realized by adopting internal segmented compressing way, no need of middle cooler
• Water cooling adopted for lowering bearing and lubricating oil temperature during operation.
• Double oil tank structure adopted to improve bearing lubrication conditions
• The inside of the blower adopts dry seal for ensuring small internal leakage

1. Special coating are sprayed on the inner surface of housing, end cover and rotor to protect blower from being corrupted by conveying gas.
2. More reliable sealing type of multiple sealing structure to ensure no gas leakage
3. PTFE oil seal is used, which has strong corrosion resistance, good pressure resistance and excellent sealing performance.
4. Inlet and outlet anti-type silencer adopted for good noise reduction effect and long service life
5. Re-flux structure adopted, when pipeline pressure is too high, gas will return to inlet pipe through the return pipe to prevent gas leakage.

1. Compact structure with same air inlet and outlet for flexible installation
2. Explosion-proof and anti-corrosion design suitable for conveying various flammable, explosive and corrosive special gas
3. Adopt stainless steel return pipe and expansion joint
4. The integrated impeller-shaft structure avoids the defects of the split type.
5. Water cooling adopted for prolonging the service life of bearing and improving the working condition of bearing
6. The interior and the surface of impeller are sprayed with special coating of good lubricity and anti-sticking properties.

• Two BKW blowers are used for series compression to reach higher pressure.
• An intercooler installed between the two blower to reduce the intake temperature of the second stage blower
• Compact structure for saving floor space
• Outlet diameter: 65~300mm
• Air capacity range: 3.32~150.88m3/min
• Applicable pressure range (discharge rising pressure): 1.0~1.5kgf/cm2

The key components of the BX Roots blower are precisely machined from stainless steel.

The key components are processed at one time in the machining center for ensuring the machining accuracy and achieving the stability of blower under different working conditions.

The impeller is made of stainless steel with special strength and rigidity enabling the impeller to meet the high-speed continuous running condition without fatigue and deformation.

Water cooling double mechanical sealing structure is adopted for ensuring reliability of the sealing system under different harsh conditions so that the leak-free operation of BX Roots blower can be promised.

BE series Roots Blower

• 45 degree angle inclined installation adopted for solving gear oil trapping problem and reducing noise
• Speed can be high or low, which improves the adjustment range of blower capacity.
• Weight is 10%-30% lighter than same type blower for realizing more smooth running and lower vibration

BH series Roots Blower

• Use high-precision three-lobe rotor, low vibration and low noise
• Integral impeller and shaft (integral cast promises the same deform when heated)
• Use special bearings of long service life
• Horizontal structure, compact structure, small size, low vibration and low energy consumption

BSW series Roots Blower

• Stable transmission, low vibration and low noise by using high-precision three-lobe rotor
• Adopt mature technology and stable water-cooled structure
• Adopt special bearings of long service life and low energy consumption
