Professional words to explain the negative pressure Roots fan, the must-know terminology in the Roots fan industry

Roots fan is the most common and basic type of fan in the market today, and is widely used in many fields, while negative pressure Roots fan is a special type of application of Roots fan. For those who are engaged in the Roots fan industry, it is very necessary to master the terminology related to negative pressure Roots fans. In this paper, the terms related to negative pressure Roots fan will be explained in detail, so that industry personnel in this area of understanding and application more in-depth.

First, the definition of negative pressure Roots fan

Negative pressure Roots fan is also known as negative pressure transmission fan, it is a use of Roots impeller inhalation of negative pressure gas and transmission fan. In short, it is a kind of equipment that utilizes the suction characteristics of Roots fan for material conveying.

Second, the working principle of negative pressure roots fan

Negative pressure Roots fan using the rotation of the Roots impeller, in the suction area to generate a negative pressure, will be transmitted to the pipeline materials through the impeller and the gap between the cylinder into the cavity, in the cavity is constantly being cut and torn crushed, and then beat into the material flow and with the rotation of the Roots impeller is pushed into the pipeline transmission.

Third, the main application areas of negative pressure Roots fan

Negative pressure Roots fan is mainly used for conveying solid granular materials, powder and fiber, etc. It is suitable for food, medicine, chemical industry, building materials and other industries. Its complete sets of equipment can realize the automatic integrated control of material conveying, storage and other processes.

Fourth, the advantages of negative pressure Roots fan

1、It has self-absorption conveying ability, does not need external air source, and has wide range of application.

2、Stable air velocity in the conveying pipeline, small abrasion, controlled material flow rate, not easy to produce clogging.

3、Applicable to a wide range of flow rate, pressure is not large, generally use negative pressure.

4, good sealing, can effectively control the material pollution.

Fifth, the main terms of negative pressure Roots fan

1, suction area: negative pressure Roots fan Roots impeller rotation in the suction area to generate a negative pressure, and through the suction hole to the gas into the fan.

2, air leakage port: in the Roots impeller rotation process, if the impeller and barrel clearance is too large will produce internal air leakage, which in turn will affect the efficiency and effectiveness of the fan. In order to reduce air leakage, the air leakage port is designed on the cylinder body.

3, vibration: fan operation if there is vibration, in addition to may affect the service life of the equipment, but also may bring noise and equipment itself is damaged. Therefore, good vibration detection and control is an important part of fan operation.

4、Impeller: It is the core component of Roots fan, and its function is to provide the energy of intake and exhaust through rotation, and complete the compression and transmission of gas.

5、Cavity: Inside the Roots fan, it is a closed space formed by two mutually engaging impellers as well as the cylinder.

6, pressure equalization system: in the negative pressure Roots fan operation, based on the pressure equalization design can reduce the pressure difference inside the machine, improve the efficiency and stability of the machine.

Six, negative pressure Roots fan maintenance specification

1、Safety protection

Ensure that the fan components and maintenance equipment is intact, improve staff and equipment safety protection capabilities.

2, equipment cleaning

Regularly clean up the dust and debris inside the fan to avoid piling up with each other, the same need to pay attention to the cleanliness and hygiene around the fan.

3、Regular maintenance

Regularly clean up the impeller, cavity and pipeline, check whether the connecting rod and bearing are worn or aging, and also check the running condition of other key parts to ensure the reliability and long-term stable operation of the equipment.

Seven, the future development trend of negative pressure Roots fan

1, technological innovation: the combination of modern technology means, such as artificial intelligence, big data, etc., to achieve more intelligent equipment, automation.

2, diversification, refinement: various industries need different transmission volume and transmission speed, the future of the negative pressure Roots fan will be more diversified, so that the transmission is more accurate.

3, safe and reliable: the reliability and safety of the fan is an important trend in the development of equipment, the future of the equipment will be more secure and controllable.

In summary, negative pressure Roots fan as one of the most widely used type of fan, the importance of the industry is self-evident. This article describes in detail the definition, working principle, main application areas, advantages, main terms, maintenance specifications and future development trends of the negative pressure Roots fan, which is believed to be inspiring and helpful for those working in this field.
