Three leaf Roots blower LGSR300

The Longgu LGSR350 Roots blower has an air flow rate of 87.1-136.7m3/min, a boost pressure of 9.8-98kpa, a motor power of 22-160kw, a fixed volume fan, and a forced gas transmission characteristic. The flow rate changes very little with pressure changes, and the conveying air is clean and free from any oil and dust pollution. The overall structure is compact, small in size, light in weight, and has a beautiful and elegant appearance. The Longgu LGSR350 three blade Roots blower adopts a special curved impeller, which has more reasonable meshing, less leakage, high efficiency, low energy consumption, energy saving and environmental protection, beautiful appearance, high-precision hard tooth synchronous gear, longer service life, low noise, and wide application, and can be used in different working conditions and environments.

Introduction to Wind Turbine

The Longgu LGSR300 three blade Roots blower adopts a new type of line, which further improves the volumetric efficiency and provides excellent air volume and pressure characteristics. The blower has reduced heat generation and temperature, and the exhaust pressure of various models can reach 0.6Kg/cm ² in dry conditions.

Fan characteristics

1. The Longgu LGSR300 three blade Roots blower adopts a fixed spiral method of 20 ° or more. The intake and exhaust shielding wires of the casing are cut into a spiral, forming a triangular intake and exhaust port with a smooth surface at the top of the rotor, which gradually opens through the rotation of the rotor.

2. The inlet and outlet of the fan do not open or close instantly like traditional Roots spiral fans, so it has the characteristics of low operating sound and low exhaust pulsation;

3. The fan adopts a three bladed linear rotor, which only needs to ensure the clearance between the rotor and the casing on the profile, with excellent performance and smooth and reliable operation.

4. Each rotor of the fan undergoes strict dynamic and static balance tests to eliminate unbalanced factors and ensure smooth and reliable operation.

5. The fan adopts a special shaped rotor, which is easy to maintain the mutual clearance between rotors and has high efficiency;

6. The fan casing does not require oil lubrication and adopts a structural design to prevent bearing and gear oil from mixing into the interior of the casing. The output air is clean and free of any oily dust.

7. The LGSR300 three blade Roots blower adopts advanced synchronous drive gears, with a wide service life and low noise.

Working principle

1. The Longgu LGSR300 three blade Roots blower is a commonly used positive displacement fan, and the amount of air delivered is proportional to the number of fan revolutions. The three bladed impeller does not rotate once and is sucked and discharged three times by two impellers. Compared with the two blade Roots blower, the Longgu LGSR300 three blade Roots blower has lower gas pulsation effect, vibration, and noise.

2. The impellers on the two shafts of the Longgu LGSR300 three blade Roots blower and the holes in the elliptical housing, as well as the clearances between the impeller end faces and the front and rear end covers of the blower, and between the blower impellers, always maintain a small gap. Under the drive of the synchronous gear, the air is transported from the blower inlet along the inner wall of the housing to the exhaust side.

3. The internal cavity of the Longgu LGSR300 three blade Roots blower does not require lubricating oil, with a simple structure, smooth operation, and stable performance.
