BLG permanent magnet variable frequency screw blower:
1.The male and female rotors of the oil-free screw blower are precisely designed. Compared with roots blower, they achieve internal compression in the cavity, and are more efficient and save more than 20% energy under the same energy consumption conditions.

2.The conveying air volume is stable, and the air volume fluctuates less with the change of pressure.

3.It has higher conveying pressure and lower operating noise.

4.It can be controlled by PLC intelligent remote control, using a variety of communication methods, and convenient operation and management.

2. Product features

Design concept:

(1) Main structure: dry oil-free twin-screw rotor design, using spiral internal compression mode, no pulse of air output. Ductile iron production, high efficiency, rotor surface coating, strong adhesion, extend the life of the main engine.

Bearings:  original composite bearings adapt to changing loads, providing a high degree of flexibility and efficiency.

Seal: Labyrinth seal, carbon ring seal combination or gas seal, magnetic oil seal combination, to provide oil-free and dust-free pure compression chamber.

(2) More efficient and energy saving: The high efficiency and energy saving screw blower adopts oil-free screw energy-saving host and permanent magnet frequency conversion system, which has more intuitive economic benefits than the traditional Roots fan. Oil-free screw blower based on the principle of thermal compression, the total efficiency of more than 75%, than Roots fan energy saving about 10%. It also has higher exhaust pressure and lower pressure pulse.

(3) More stable and reliable: After high temperature performance test, durable and reliable, multi-duct air intake, can overcome a variety of complex conditions.

(4) Lower noise: The pneumatic noise of the screw fan is very small, the smooth output eliminates the sudden release of the internal air, and the air rattle of the wavy inlet and outlet is reduced, making the fan noise less than the traditional blower, without whistling. Due to the internal compression of the helical rotor, the pressure impact noise of the blower outlet pressure and pipeline pressure is eliminated, the gas is output smoothly, and the wave inlet and air outlet reduce the airflow fluctuation. Box screw overall noise ≤85 dB.
(5) Stability

Compared with Roots blowers:

The unit has small leakage, low temperature rise and strong pressure boost, up to 150KPa (1.5bar).

Compared with centrifugal blowers:

Strong adaptability to working conditions, no surge, flow rate almost does not change with pressure changes.

(6) Intelligence

The integrated skid box can be installed and moved as a whole. Site installation workload is less, only need to complete the interface pipe

The connection between the road and the external electrical can work.

The box is integrated with temperature and pressure monitoring instrument, signal control module, frequency converter, touch screen and other electrical components, without additional installation.

Operation control system: integrated station monitoring instrument, signal control module, frequency converter, touch screen and other no additional installation, optimize the selection of driving components, parameter setting class accurate to achieve high efficiency, automatic control and protection functions, while realizing online control and remote control, a variety of operating modes, users can adjust the power saving operation according to changes in working conditions.

(7) Low cost: The optimized structural design enables us to consume less, ensure the durability of the product, and the unit runs smoothly, the load is small, and no special infrastructure is required.

(8) Self-lubrication: the host internal oil dumping device, suitable for low pressure, 40~90KPar, some models can be used to 120KPa.

(9) Forced lubrication: the main engine has no lubrication device, and the oil pump needs to be forced to supply oil to achieve the effect of lubrication and cooling. Applicable pressure up to 150KPa.
