Working principle and characteristics of pneumatic conveying roots blower
The selection of air source is very important in the pneumatic conveying roots blower management system. Some pneumatic conveying systems use air compressors on site, and some use roots blowers. Maybe both of them were originally selected as gas sources for development, but they have their own strengths. Then pneumatic conveying can be divided into dilute phase pneumatic conveying and dense phase high-pressure pneumatic conveying. Usually, roots blower is used at low pressure and air compressor is used at high pressure.
Characteristics of pneumatic conveying Roots blower:
1. In the fixed spiral mode with a spiral shape of more than 20, the shell inlet and exhaust shield wires enter the spiral and gradually open through the rotation of the rotor. The inlet and exhaust pulsations are slight and the operation sound is small. The rotor adopts a special shape, which can maintain the gap between the rotors and further improve the power.
3. The rotor is a three blade straight line, and the rotor with small axial displacement contacts. The clearance of the rotor can be ensured.
4. There is no functional error between fans due to the use of precision CNC machine tools to produce rotors. In addition, the rotor is always in a balanced state during manufacturing. The machine does not vibrate during operation.
5. The selection of gears for the high-end market drive system not only effectively extends the service life, but also reduces the noise. Therefore, the adverse disturbance of gears to commodities is completely eliminated.
6. The other is a structural design in which the output air is clean, does not contain any oil dust, the interior of the box does not need oil lubrication, and the bearing gear oil does not mix into the interior of the box.
In the use of Roots blower for pneumatic conveying, the selection of air source is very important. The main action time of conveying main force is in the air source. As long as the air source equipment is correctly selected, more work can be completed. Under normal use, it takes a little energy to transport the powder using an air compressor. Now we need to consider pressure and flow, so this equipment management can not achieve the research of energy-saving technology very quickly, and the flow of people that must be used together is also unqualified, and the area is also very large. The electric and diesel engines drive the air compressor through the V-belt, change the crankshaft structure, change the rotation direction, analyze the connecting rod, and make the piston reciprocate. Although the air compressor may rotate in the work of low-pressure pneumatic conveying, it may not be able to better achieve the expected conveying output value. Without considering the air compressor, through scientific and meticulous skill education and practice, roots blower, a low-pressure continuous transmission air source in different professional fields, is used to perfectly solve this part of the problem.
