Key words: "what is roots blower", "roots blower manufacturer"

Roots blower is a transliteration of Roots blower in English. Roots is a family name in the United States, which is translated as roots. Francis roots and Frances roots brothers invented it in 1854. It belongs to rotary positive displacement compressor fan. Because the discharge pressure (< 0.2MPa) is within the scope of low-pressure blower, it is generally known as roots blower Roots blower

So roots is just a name, it represents a new type of blower, this kind of blower is different from the ordinary fan relying on blade blowing. The principle of this kind of blower is that the air is pushed outwards by the rotation of the impeller. Its pressure is much higher than that of the ordinary blower, and it has the characteristics of forced air supply. The air pump can be replaced in many occasions. Zhangqiu Hongguang Machinery Co., Ltd Roots blower For more than 10 years, it has been recognized by users in the industry. Its products are sold all over the country and exported to various countries. Some users do not know about this kind of fan. Today, Hongguang "roots blower manufacturer" introduces it from the following points.

1、 Composition

  a、 Roots blower It is composed of shell, wallboard, impeller, oil tank and muffler.

B. shell: mainly used for supporting (wallboard, impeller, muffler) and fixing.

C. wallboard: it is mainly used to connect the casing and impeller, support the rotation of impeller, and achieve the effect of end face sealing.

D. impeller: Yes Roots blower The rotating parts are divided into two and three blades. However, the three blade type has gradually replaced the two leaf type because of its advantages of small export pulsation, low noise and stable operation.

E. oil tank: mainly used for storing lubricating oil of gear and bearing.

F. muffler: used to reduce the noise generated by the air flow pulsation when roots blower is in and out.

2、 Principle

   Roots blower It is a kind of positive displacement blower. Two three blade impellers rotate relatively in the space sealed by shell and wall plate. Because each impeller is enveloped by involute or epicycloid, the three blades of each impeller are identical, while the two impellers are identical, so the machining difficulty is greatly reduced. When machining the impeller, the numerical control equipment is used to ensure that the minimum clearance can be maintained no matter where the two impellers rotate under the condition that the center distance of the two impellers remains unchanged, so as to ensure that the gas leakage is within the allowable range.

The two impellers rotate in reverse. Because the gap between impeller and impeller, impeller and shell, impeller and wall plate is very small, the air inlet forms a vacuum state. Under the action of atmospheric pressure, air enters the intake chamber. Then, the two blades of each impeller form a sealing chamber with the wall plate and the shell. During the impeller rotation, the air in the inlet chamber is continuously transported to the exhaust chamber through a seal chamber formed by two blades. Because the impellers in the exhaust chamber mesh with each other, the air between the two blades is squeezed out, thus the continuous operation, the air is continuously transported from the inlet to the outlet, which is the whole working process of Roots blower.

3、 Service conditions

The inlet temperature of the conveying medium shall not exceed 1.40 ℃.

2. The content of particles in the medium shall not exceed 100 mg / m3, and the maximum size of particles shall not exceed half of the minimum working clearance.

3. The bearing temperature shall not be higher than 95 ℃ and the lubricating oil temperature shall not be higher than 65 ℃.

4. The working pressure shall not be higher than the pressurization range specified on the rating plate.

  5. Roots blower The clearance between impeller and casing, impeller and side plate, impeller and impeller has been adjusted before delivery. Ensure clearance when reassembling.

6. During operation, the oil level of main oil tank and auxiliary oil tank must be between two red lines of oil level gauge.

7. Check whether the connection parts of the inlet and outlet have forgotten to fasten, and whether the pipe supports are complete. For blowers and vacuum pumps requiring cooling water, check whether the installation of cooling water meets the requirements.

4、 Main features

Due to the use of the three blade rotor structure, the structure of the air inlet and outlet in the shell is reasonable, the fan vibration is small and the noise is low. Impeller and shaft are integrated structure, impeller no wear, fan performance is constant for a long time, fan can run continuously for a long time. The fan has the advantages of large volume utilization, high volume efficiency, compact structure and flexible installation mode. Complete models can meet the needs of different users and different purposes.

Conclusion: the above is Hongguang Roots blower What is roots blower introduced by the manufacturer? I think you will have a new understanding of this fan after reading this article, so that you can see whether you need it according to your own production process, Roots blower It is widely used in aquaculture aeration, sewage treatment aeration, cement transportation, and is more suitable for gas transportation and pressure system in low pressure occasions, and can also be used as vacuum pump.
