Three leaf Roots blower LGSR200

The Longgu LGSR200 Roots blower belongs to our company's LGSR series of three leaf Roots blowers, with an air volume of 27.65-58.81m3/min, a boost of 9.8-98kpa, and a motor power of 15-90kw. It can be used in different industries such as pneumatic conveying, powder conveying, aquaculture, sewage treatment, chemical industry, and power. There are different types of Roots blowers, including explosion-proof Roots blowers, special sealed Roots blowers, piston ring sealed Roots blowers, water-cooled Roots blowers, and double oil tank Roots blowers. The compact structure, low operating noise, long service life, and stable and reliable operation for a long time. Conventional models can be used to transport air and other inert gases, while special sealed explosion-proof Roots blowers can be used to transport toxic and harmful gases in flammable and explosive machines. They are well sealed and have no defects. Leakage.

Introduction to Wind Turbine

The Longgu LGSR200 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/cm2 in dry conditions;.

Fan characteristics

1. The Longgu LGSR200 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 LGSR200 three blade Roots blower adopts advanced synchronous drive gears, with a wide service life and low noise

Working principle

1. The Longgu LGSR200 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 LGSR200 three blade Roots blower has lower gas pulsation effect, vibration, and noise.

2. The impellers on the two shafts of the Longgu LGSR200 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 LGSR200 three blade Roots blower does not require lubricating oil, with a simple structure, smooth operation, and stable performance.
