Product Application
As a kind of typical gas pressurization and conveying machinery, roots blower in the specific pressure area has wide applicable characteristics. The traffic is usually 0.5 ~ 800 m3 / min, up to about 1400 m3 / min, single stage work pressure of 53.3 ~ 98 kpa, two-stage series, which can realize - 80 ~ 200 kpa.

In terms of application, most of roots blower for the use of air blower. Their use in building materials, electric power, metallurgy, paper making, aquaculture and so on many fields.
Blower working principle
Roots blower is a double rotor compressor, the axis of the two rotors are parallel to each other. The rotor is composed of an impeller and a shaft, and the impeller and the impeller, the impeller and the casing and the wall plate are provided with a tiny gap to avoid mutual contact friction. Two the rotor is driven by a pair of synchronous gears driven by the original, and is rotated in the opposite direction.
With the mutual engagement of the two gears, the inlet and outlet of the blower are not communicated directly. The impeller and the casing and the wall plate are enclosed into the base unit volume, so as to achieve the effect of conveying gas.
Main Features:
1. Speed roots blower can also be used for coupling transmission..
2. The selected motor is generally 4 motors, voltage 380V.
3. When the boost is greater than 63.7kPa, it is a high pressure fan, marked as NSR- II -H.
4. NSR- II series Roots blower standard with double fuel tank.
5. When 73.5kPa6. Fan tank water cooling water consumption is 5-7L/min, the cooling water inlet temperature is not higher than 25 DEG C, the inlet pressure is 196kPa (tap water pressure can)

i, High-pressure Roots Blower Low noise
Hot-Sale Roots Air Blower for Reverse Cleaning of Filter Bags with adoption of helical tri-lobe roots rotors and the discharge port of special geometry, the airflow noise is much lower compared to typical straight-lobe roots blower. The noise level can be reduced by 8db in the band of low frequency; hence the noise in the surroundings of blower can be significantly improved.

JHJHBJH
ii, High adiabatic efficiency
High-pressure Roots Blower with design of helical tri-lobe roots rotors, Hot-Sale Roots Air Blower for Reverse Cleaning of Filter Bags the airflow pulsation is less and the air streamline would be more stable. Therefore the fluctuation in airflow is less and then the energy waste can be reduced. Additionally, the instantaneous backflow of discharge is lower by the design of special discharge port. Compared to straight-lobe roots blower, the adiabatic efficiency can be raised up to 20%.

HJJHBJH
iii, High-pressure Roots Blower Super Energy saving
Compared to the typicalHot-Sale Roots Air Blower for Reverse Cleaning of Filter Bags under the same operation conditions of discharge pressure and airflow volume, the power consumption of helical tri-lobe roots blower will be lower by 20.
