What is a Vacuum negative pressure Roots blower? Introduction to the advantages and characteristics of blower functions

Vacuum negative pressure Roots bloweris a positive displacement blower with forced gas transmission characteristics.，it has the characteristics of run smoothly, Precise control, wide application range, convenient maintenance and strong adaptability。

1、Brief introduction of Vacuum negative pressure Roots blower

Vacuum negative pressure Roots bloweris a device that generates positive pressure or negative pressure through the relative rotation of two impellers, thus compressing and conveying gas.，is a Vacuum negative pressure Roots blower newly developed by hyde powder。

3、Structural advantages of Vacuum negative pressure Roots blower

The Vacuum negative pressure Roots blower has the following structure

1. muffler

Used to reduce the noise caused by airflow pulsation when the Vacuum negative pressure Roots blower enters and exits.

2. fuel tank

Mainly used for storing lubricating oil used for lubricating gears and bearings. The oil tank is used to store lubricating oil to lubricate bearings and gears and reduce wear and friction.

3. impeller

It is the rotating part of the Vacuum negative pressure Roots blower, which is divided into two leaves and three leaves. However, due to many advantages such as smaller air pulsation, less noise and smoother operation, the three-leaf Vacuum negative pressure Roots blower has gradually replaced the two-leaf Vacuum negative pressure Roots blower.

4. case

It mainly plays the role of supporting (wallboard, impeller, muffler) and fixing. The casing is the external structure of the Vacuum negative pressure Roots blower, which is used to support and fix the rotor, bearings and other components, while ensuring the gas tightness.

5. bearing

It is used to support the rotation of the rotor and bear the weight of the rotor and the load during operation.

4、Working principle of Vacuum negative pressure Roots blower

Vacuum negative pressure Roots blowerWhen the motor drives one impeller to rotate, the other impeller will rotate synchronously at the same speed and in the opposite direction under the action of the synchronous gear. In the process of rotation, because the gaps between impeller and impeller, impeller and casing, impeller and wallboard are very small, a vacuum state is formed at the air inlet, and air is sucked into the air inlet cavity under the action of atmospheric pressure. As the impeller continues to rotate, two blades of each impeller, the wallboard and the casing form a sealed cavity, and the air in the air inlet cavity is continuously brought to the exhaust cavity by the sealed cavity formed by the two blades. Because the impellers in the exhaust cavity are meshed with each other, the air between the two blades is squeezed out. After continuous inhalation and extrusion, air is continuously transported from the air inlet to the air outlet, completing the whole gas transportation process.，can be customized according to user's needs.。

5、Introduction of Vacuum negative pressure Roots blower characteristics

Vacuum negative pressure Roots blowersmooth operation,convenient manufacture,low noise,energy-efficient,economical and durable，is an efficient volumetric gas conveying and pressurizing equipment.，in the course of work,The two three-blade impellers rotate relatively in the space sealed by the casing and the wallboard. Each impeller adopts the envelope of involute or epicycloid, the three blades of each impeller are exactly the same, and the two impellers are also exactly the same, which greatly reduces the machining difficulty. During the rotation of the impeller, air enters the air inlet cavity under the action of atmospheric pressure, and then two blades of each impeller, the wallboard and the casing form a sealed cavity. During the rotation of the impeller, the air in the air inlet cavity is continuously brought to the exhaust cavity by the sealed cavity formed by the two blades, and because the impellers in the exhaust cavity are meshed with each other, the air between the two blades is squeezed out, so that the air is continuously transported from the air inlet to the air outlet.，has been favored by more and more customers.。

6、Company selection skills

Choosing a suitable Vacuum negative pressure Roots blower manufacturer requires comprehensive consideration of many aspects. First of all, we should examine the strength of manufacturers, including production capacity, R&D team and industry experience. Strong manufacturers can better ensure product supply and innovation ability. Secondly, product quality is the key, and it is evaluated by product certification, material selection and manufacturing process to ensure the durability of products. Product performance can not be ignored, so we should choose manufacturers with matching technical parameters, rich types and customized services according to actual needs. After-sales service is equally important. Professional and timely service team, perfect after-sales content and extensive service network can make users worry about nothing. In addition, market reputation is also an important reference. We can understand the reputation and status of manufacturers through customer evaluation, industry reputation and award-winning honor. Finally, it is necessary to analyze the price and cost performance, and on the premise of ensuring the quality and performance, choose a manufacturer with reasonable price and high cost performance, so as to purchase Vacuum negative pressure Roots blower products that meet the demand and have good cost performance.。
