The Longgu LGSR65 Roots blower belongs to our company's LGSR series Roots blower, with a flow range of 1.67-3.65m3/min, a boost of 9.8-98kpa, and a motor power of 0.55-55k. We continuously improve our technology by integrating advanced domestic and foreign technologies, using modern fan production and processing centers, high-precision hard tooth synchronous gears, high production and processing accuracy, long service life, low noise, and high cost-effectiveness. The impeller of the LGSR65 three blade Roots blower is manufactured with a special curve processing, which ensures more reasonable meshing during operation, less leakage, high operating efficiency, clean conveying air, no oil and dust pollution, and good conveying quality.
The Longgu LGSR65 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 various models have high exhaust pressure when used in dry conditions
1. The Longgu LGSR65 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 LGSR65 three blade Roots blower adopts advanced synchronous drive gears, with a wide service life and low noise
1. The Longgu LGSR65 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 LGSR65 three blade Roots blower has lower gas pulsation effect, vibration, and noise.
2. The impellers on the two shafts of the Longgu LGSR65 three blade Roots blower and the holes in the elliptical housing, as well as between the impeller end faces and the front and rear end covers of the fan, and between the fan impellers, always maintain a small gap. Under the drive of the synchronous gear, the air is transported from the fan inlet along the inner wall of the housing to the exhaust side.
3. The internal cavity of the Longgu LGSR65 three blade Roots blower does not require lubricating oil, with a simple structure, smooth operation, and stable performance.
