What is a Negative pressure three blade Roots blower? Introduction to the Working Principle of blower

Negative pressure three blade Roots blowera rotary compressor that uses two lobed rotors to move relative to each other in a cylinder to compress and transport gas.，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.。The following is to introduce the Negative pressure three blade Roots blower:

1、Brief introduction of Negative pressure three blade Roots blower

Negative pressure three blade Roots bloweris a double impeller synchronous compression machine, belonging to a positive displacement blower.，is a popular Negative pressure three blade Roots blower，it has been widely used in Flue gas treatment, pneumatic transport, water treatment, smelt, petrify and other industries。

2、Negative pressure three blade Roots blower field real shot

The following is the live video of Negative pressure three blade Roots blower designed and produced by hyde for users, from which we can see the the advantage is In the process of air intake and exhaust, the Negative pressure three blade 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.、Simple structural design, stable and reliable operation and convenient maintenance. This enables it to maintain high working efficiency and stability in long-term operation.、Because of the design of three-blade rotor, the Negative pressure three blade Roots blower has little vibration and low noise during operation, and the operation is stable and reliable、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 three blade Roots blower less vibration and noise.、In the process of air intake and exhaust, the Negative pressure three blade 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. of hyde powderNegative pressure three blade Roots blower.。

As you can see from the live video.，hyde powder widely used inmine,petrochemical industry,chemical fertilizer,power,aquaculture and other industries。

3、Introduction of advantages of Negative pressure three blade Roots blower

Negative pressure three blade Roots blowers have the following advantages.

1. Wide application range

Widely used in many fields, such as commodity industry, etc., it is more suitable for gas transportation and pressurization systems in low-pressure occasions, and can also be used as vacuum pumps.

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 Negative pressure three blade Roots blower is relatively simple and easy to maintain.

4. Long service life

The mechanical friction of the Negative pressure three blade 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.

5. Run smoothly

Due to the design of three-blade rotor, the Negative pressure three blade Roots blower has little vibration and low noise during operation, and the operation is stable and reliable.

4、Negative pressure three blade Roots blower function

Negative pressure three blade Roots blowerit has the functions of aeration, cool, pressurized transportation, mix and material handling，it is widely used inpneumatic transport,water treatment,coal chemical industry,pottery and porcelain,power and other industries，it is mainly composed of fuel tank, case, wallboard, bearing and case，This productThe overall structural design is simple, diverse and beautiful.，at runtime,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.，is carefully developed by hyde combined with advanced technology。

6、Negative pressure three blade Roots blower application

Negative pressure three blade Roots blowerIt has the functions of aquaculture, Material fluidization, sewage disposal, dehydrate and exhaust emission，the principle is simple.It mainly depends on the relative movement of two lobed rotors (usually three-bladed impellers) in the cylinder to compress and transport gas.，it has the characteristics of run smoothly, energy-efficient, wide application range, wide application range and Precise control，low in price，be of high quality。

Negative pressure three blade Roots blower

Negative pressure three blade Roots blowerat work,The gas is compressed and transported by the relative rotation of a pair of trilobal rotors in the cylinder. Each trilobal rotor is supported by two bearings, and the relative position of the two rotors is always kept constant by using a pair of synchronous gears. During the rotation of the rotor, there are tiny gaps between impeller and impeller, impeller and casing, impeller and side cover, so there is no friction in the working chamber and no lubrication is needed, thus realizing the smooth transportation of gas.，Simple structure and reliable operation.，the main structure includes case, muffler, muffler, rotator and impeller，the product looks atmospheric.。
