Introduction to HDSR250V Roots Vacuum Pump, advantages, characteristics and principles of Roots Blower

HDSR250V Roots Vacuum Pumpa rotary compressor that uses two lobed rotors to move relative to each other in a cylinder to compress and transport gas.，Gas is compressed and transported based on the relative motion of two lobed rotors in the cylinder. When the two rotors rotate, the volume between them changes constantly, thus realizing the suction, compression and discharge of gas.，Mainly used foraeration,cool,mix,aeration andexhaust emission，the product looks beautiful.，it is widely used inport,pottery and porcelain,Pharmaceutical and chemical industries,manufacturing industry,petrify and other industries。The following is to introduce the HDSR250V Roots Vacuum Pump:

1、Brief introduction of HDSR250V Roots Vacuum Pump

HDSR250V Roots Vacuum Pumpis a double impeller synchronous compression machine, belonging to a positive displacement blower.，at work,It mainly depends on the relative movement of two lobed rotors (usually three-bladed impellers) in the cylinder to compress and transport gas.，is a kind of high quality and low price HDSR250V Roots Vacuum Pump。

2、Introduction of advantages of HDSR250V Roots Vacuum Pump

HDSR250V Roots Vacuum Pumps have the following advantages.

1. Smooth operation

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.

2. Economical and durable

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

3. Convenient maintenance

The structure of the HDSR250V Roots Vacuum Pump is relatively simple and easy to maintain.

4. Compact structure and small floor space.

The HDSR250V Roots Vacuum Pump is small in size and occupies a small area, which makes it easy to arrange and install in places with limited space.

5. Long service life

The mechanical friction of the HDSR250V Roots Vacuum Pump 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.

Speak directly with facts on the spot。

HDSR250V Roots Vacuum Pump

As you can see from the live video.，Shandong Haide Fenti Engineering Co., Ltd. is a device that generates positive pressure or negative pressure through the relative rotation of two impellers, thus compressing and conveying gas.。

4、HDSR250V Roots Vacuum Pump structure

The HDSR250V Roots Vacuum Pump structure is introduced as follows:

1. impeller

It is the rotating part of the HDSR250V Roots Vacuum Pump, 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 HDSR250V Roots Vacuum Pump has gradually replaced the two-leaf HDSR250V Roots Vacuum Pump.

2. 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.

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. rotator

The core components are two identical lobed rotors, which usually adopt involute or epicycloid envelope design to ensure close cooperation during rotation and reduce leakage.

5. case

It mainly plays the role of supporting (wallboard, impeller, muffler) and fixing. The casing is the external structure of the HDSR250V Roots Vacuum Pump, which is used to support and fix the rotor, bearings and other components, while ensuring the gas tightness.

5、Working principle of HDSR250V Roots Vacuum Pump

HDSR250V Roots Vacuum Pumpat 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 mainly composed of rotator, bearing, case, wallboard and muffler，it has the functions of aeration, material fluidization, supply air, cool and desulfurization oxidation。

HDSR250V Roots Vacuum Pumpthe product looks atmospheric.，widely used inpower,sewage disposal,chemical fertilizer,Food and beverage processing,pneumatic transport and other industries，The structural form of the three-blade rotor and the reasonable structure of the air inlet and outlet in the shell make the HDSR250V Roots Vacuum Pump less vibration and noise.、Small size and small floor space make it easy to arrange and install in places with limited space.、Due to the adoption of synchronous gear transmission and small gap design, the HDSR250V Roots Vacuum Pump runs stably and reliably, without contact and wear parts, and has a long service life.、Because of the design of three-blade rotor, the HDSR250V Roots Vacuum Pump has little vibration and low noise during operation, and the operation is stable and reliable、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 HDSR250V Roots Vacuum Pump perform well in many situations where stable airflow is needed.。
