Introduction to Negative pressure Roots blower, Roots Blower advantages, characteristics and principles

Negative pressure Roots bloweris a double impeller synchronous compression machine, belonging to a positive displacement blower.，low noise,run smoothly,durable performance,economical and durable,convenient manufacture，it has the functions of desulfurization oxidation, material fluidization, pressurized transportation, pick up the suction and exhaust emission。The following is to introduce the Negative pressure Roots blower:

1、Brief introduction of Negative pressure Roots blower

Negative pressure Roots blowerthe models are complete and can meet the needs of different users for different purposes.，the product looks atmospheric.，The structural form of the three-blade rotor and the reasonable structure of the air inlet and outlet in the shell make the fan have small vibration and low noise.、The air volume is directly proportional to the rotating speed, so its air output is very stable and basically unaffected by pressure changes. This characteristic makes the Negative pressure Roots blower perform well in many situations where stable airflow is needed.、The structural form of the three-blade rotor and the reasonable structure of the air inlet and outlet in the shell make the Negative pressure Roots blower less vibration and noise.、Due to the adoption of synchronous gear transmission and small gap design, the Negative pressure Roots blower runs stably and reliably, without contact and wear parts, and has a long service life.、In the process of air intake and exhaust, the Negative pressure Roots blower will not produce air pulsation, which means that it does not need an additional buffer gas tank to output gas smoothly. This is particularly important for processes that require stable airflow.，at the start of the operation,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.，it is usually composed of bearing, case, impeller, bearing and case。

3、Negative pressure Roots blower performance advantage

The advantages of Negative pressure Roots blower are as follows:

1. Compact structure and small floor space.

The Negative pressure Roots blower is small in size and occupies a small area, which makes it easy to arrange and install in places with limited space.

2. Convenient maintenance

The structure of the Negative pressure Roots blower is relatively simple and easy to maintain.

3. Long service life

The mechanical friction of the Negative pressure Roots blower is small and the loss is low, so its service life is relatively long. This enables it to maintain high working efficiency and stability in long-term operation.

4. Run smoothly

The structure form of the three-blade rotor and the reasonable structure of the air inlet and outlet in the shell make the fan have small vibration and low noise.

5. Economical and durable

The design without lubrication reduces the maintenance cost and improves the economy of the equipment.

4、Negative pressure Roots blower structure composition

The Negative pressure Roots blower has the following structure

1. case

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

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. bearing

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

4. wallboard

It is mainly used to connect the casing with the impeller, support the rotation of the impeller, and play the role of end sealing.

5. muffler

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

5、Negative pressure Roots blower principle

Negative pressure Roots blowerat work,Gas is compressed and transported based on the relative motion of two lobed rotors in the cylinder.，usually used in manufacturing industry, power, smelt, make paper, chemical fertilizer and other fields，Simple structure and reliable operation.，generally, it is composed of muffler, case, bearing, impeller, rotator and other major components，the advantage is It has high efficiency and can realize gas transportation and pressurization with low energy consumption.、The air volume is directly proportional to the rotating speed, so its air output is very stable and basically unaffected by pressure changes. This characteristic makes the Negative pressure Roots blower perform well in many situations where stable airflow is needed.、Due to the adoption of synchronous gear transmission and small gap design, the Negative pressure Roots blower runs stably and reliably, without contact and wear parts, and has a long service life.、The structural form of the three-blade rotor and the reasonable structure of the air inlet and outlet in the shell make the Negative pressure Roots blower less vibration and noise.、Because of the design of three-blade rotor, the Negative pressure Roots blower has little vibration and low noise during operation, and the operation is stable and reliable，Widely used in Material fluidization, dry, Pressurized transportation, exhaust emission and pick up the suction。
