Pneumatic conveying roots blower It is very important to select a gas source for the management system. When some users raise some questions, it seems that some of our pneumatic conveying systems use air compressors on site, while others use Roots blowers. Maybe both of them were chosen to develop as gas sources, but they have their own advantages. Then pneumatic conveying can be divided into dilute phase pneumatic conveying and dense phase high-pressure pneumatic conveying. Normally, roots blower is used for low-pressure ones and air compressor is used for high-pressure ones.

Features of Roots blower for pneumatic conveying:

1. In the fixed spiral mode where the spiral shape is more than 20 °, the air inlet and exhaust shield wires of the shell enter the spiral and gradually open through the rotation of the rotor. The air inlet and exhaust pulsation is slight and the operation sound is low.

In addition, the special shape of the rotor can maintain the clearance between the rotors and further improve the power.

3. Since the rotor is a three blade straight line, the rotor with small axial displacement contacts. To ensure that the rotor clearance is OK.

4. There is no functional error between fans due to the use of fine CNC machine tools to produce rotors. In addition, the rotor has been in a balanced state during the manufacturing process. The machine does not vibrate during operation.

5. When we select some high-end market drive system gears, not only the life span is effectively extended, but also the low noise is ended. Therefore, the bad disturbance of the goods from the gear pair is thoroughly swept away.

6. The other is that the output air is clean, free of any oil dust, and there is no need for oil lubrication inside the casing, and the structural design to prevent bearing gear oil from mixing into the casing is selected.

The company has established a production management system based on the quality ISO 9001 standard, with the goal of exchanging terminal parts, reducing production costs and short-term delivery.

In the use of the pneumatic conveying roots blower, the selection of air source is very important. The main working time of the main feeding force is in the air source. As long as we select the right air source equipment, we can achieve the ash conveying function of twice the result with half the effort. Therefore, some student brothers think that if we can use the air compressor as the air source if the conveying distance is far away, isn't it OK for us? It is not the case originally. Generally speaking, the use of air compressor for powder conveying consumes a bit of energy. Now we need to think about the pressure and flow. The equipment management not only can not reach the research on the role of energy-saving technology in time, but also needs to use the combined flow of people. In addition, the company also occupies a large area, which is composed of electric vehicles The compressor of diesel engine is driven by V-belt, so that the crankshaft structure changes the rotation direction, and the piston reciprocates by analyzing the connecting rod. Sometimes the air compressor may not be able to complete the estimated transportation output value when it is operated under low-pressure pneumatic transportation. We don't think about air compressors. Through scientific and careful skills education and practice, we choose low pressure continuous pneumatic conveying air source of different majors - Roots blower, which will perfect the information processing problem.

Therefore, the teaching method of knowledge and skills of continuous transportation in our country, together with the fact that the pneumatic transmission power air source is usually designed to use the pneumatic transmission roots blower, so the power air source usually does not need to establish an effective purification network system, only has certain requirements for air volume and pressure, and can use the independent air source or the compressor station air source commonly used in the project (centralized air source).

Therefore, the selection of pneumatic conveying air source between Roots blower and air compressor can be judged according to the financial situation!
