What is a Negative pressure pumping Roots vacuum pump? Introduction to the advantages and characteristics of the roots vacuum pump functions

Negative pressure pumping Roots vacuum pumpis an efficient and reliable vacuum equipment.，Mainly used forvacuum treatment,Vacuum extraction,vacuum packaging,Gas treatment andvacuum distillation，the advantage is In the process of air intake and exhaust, the Negative pressure pumping Roots vacuum pump 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.、It has high efficiency and can realize gas transportation and pressurization with low energy consumption.、Small size and small floor space make it easy to arrange and install in places with limited space.、Simple structural design, stable and reliable operation and convenient maintenance. This enables it to maintain high working efficiency and stability in long-term operation.、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 pumping Roots vacuum pump less vibration and noise.，Cheap and high quality。

1、Brief introduction of Negative pressure pumping Roots vacuum pump

Negative pressure pumping Roots vacuum pumpbelonging to a rotary vacuum pump.，in the course of work,the suction, compression and exhaust processes are completed by synchronous high-speed rotation of two or more trilobal rotors in the pump cavity. The rotor consists of three blades, whose shapes and positions are symmetrical. When the motor is started, the two rotors start to rotate. Due to the symmetry of the design and position of the blades, air enters the pump body from the air inlet, and is gradually squeezed and discharged by the blades, forming a vacuum.，is based on hyde powder is a kind of Negative pressure pumping Roots vacuum pump manufactured by hyde powder。

2、Functional advantages of Negative pressure pumping Roots vacuum pump

Negative pressure pumping Roots vacuum pumps have the following advantages.

1. Wide application range

Negative pressure pumping Roots vacuum pumps are suitable for many industries, such as smelt and other fields, and are used in various technological processes such as vacuum distillation, drying, purification, pumping and vacuum packaging.

2. stability

The structure is simple and practical, and there is no need to refuel, so it has little impact on the environment and gas pollution. In addition, because the rotor adopts a trilobal shape, the vibration and noise generated by its movement are very small and the operation is stable.

3. reliability

Because there is no liquid and oil film, the Negative pressure pumping Roots vacuum pump will not have oil leakage and other problems, with longer service life and lower maintenance cost.

4. Long service life

The rotor of the Negative pressure pumping Roots vacuum pump is usually made of wear-resistant materials, and the structure of the pump body is firm, so the service life is relatively long.

5. high-effect

The Negative pressure pumping Roots vacuum pump has very high pumping speed and exhaust capacity, especially in the range of high vacuum, and its performance is particularly outstanding.

4、Negative pressure pumping Roots vacuum pump structure

The Negative pressure pumping Roots vacuum pump has the following structure

1. pump body

Pump body is usually made of cast iron or cast steel, which has good strength and sealing performance.

2. sealing device

The sealing device is used to ensure that the gas in the pump cavity will not leak to the external environment.

3. bearing

Bearings are responsible for supporting the rotary motion of the rotor, and high-precision bearings are usually used to ensure the stable operation of the rotor.

4. gearing

The transmission device is usually driven by motor or reducer, which makes the rotor rotate relatively in the pump cavity.

5. rotator

Rotor is the core component of the Negative pressure pumping Roots vacuum pump, and its profile design and machining accuracy directly affect the performance and service life of the pump.

5、Negative pressure pumping Roots vacuum pump function

Negative pressure pumping Roots vacuum pumpmultifunctional, with functions such as dehydrate, pick up the suction, cool, material handling and Desulfurization oxidation，Widely used inGas treatment,vacuum packaging,vacuum drying,Vacuum extraction,vacuum treatment and so on，the principle is simple.the suction, compression and exhaust processes are completed by synchronous high-speed rotation of two or more trilobal rotors in the pump cavity. The rotor consists of three blades, whose shapes and positions are symmetrical. When the motor is started, the two rotors start to rotate. Due to the symmetry of the design and position of the blades, air enters the pump body from the air inlet, and is gradually squeezed and discharged by the blades, forming a vacuum.，at the start of the operation,mainly based on the relative rotational movement of the rotor in the pump chamber. There are two rotors in the pump, and a certain gap is kept between them and the inner wall of the pump shell. Through the rotation of the rotor, the gas is sucked in from the air inlet, and then discharged from the air outlet through the processes of compression and exhaust. Due to the special design of the rotor profile, the gas in the pump cavity is effectively compressed and discharged, thus achieving vacuum extraction.，the product looks beautiful.。

6、Negative pressure pumping Roots vacuum pump application

Negative pressure pumping Roots vacuum pumpIt can be used for vacuum distillation, vacuum packaging, Gas treatment, vacuum drying, Vacuum extraction, vacuum treatment and so on，is a kind of vacuum equipment that uses a pair of rotors (usually two impellers with special profile) that rotate synchronously and reversely in the pump cavity to extract gas.。

Negative pressure pumping Roots vacuum pumpThe 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 pumping Roots vacuum pump 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 pumping Roots vacuum pump runs stably and reliably, without contact and wear parts, and has a long service life.、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 Negative pressure pumping Roots vacuum pump 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 pumping Roots vacuum pump less vibration and noise.，the principle is simple.mainly based on the relative rotational movement of the rotor in the pump chamber.
