Tri lobe blower

What is a tri lobe blower?

The three-blade Roots blower is a commonly used volumetric fan. It is mainly composed of three intermeshing impellers (rotors), so it is also called a three-blade Roots blower. The working principle of this blower is based on the spatial changes between the impellers to compress and transport gas.
Specifically, when two impellers mesh and rotate with each other, the space between them will periodically expand and contract as the impellers rotate, thereby sucking in gas and compressing the gas between the impellers, and finally discharging the compressed gas. go out. In this way, the Roots blower can suck in air and compress it in continuous rotation to achieve the purpose of transporting gas.

The main features of the three-blade Roots blower include:

1.High efficiency: The design of the three-blade Roots blower can achieve high efficiency and maintain efficient gas delivery even when operating at low speed.
2.Low noise: Due to the large gaps between the impellers and between the impellers and the casing, the noise generated during operation is low.
3.The transported gas is pure: Since there is no metal contact between the impellers, gases containing solid particles or viscous components can be transported without causing secondary pollution to the gas.
4.Simple structure: The structure of the three-blade Roots blower is relatively simple, mainly composed of an impeller, a casing and a transmission system, which is easy to maintain and maintain.
5.Stable operation: The impellers rotate in the same direction, making the fan operate smoothly and with little vibration.
6.Wide range: It has a wide range of applications and can be used in chemical industry, environmental protection, water treatment, food, pharmaceutical and other industries.

What is the difference between twin lobe and tri lobe blowers?

1.Number of leaves
The main difference between a two-blade fan and a three-blade fan is the number of blades. A two-blade fan has only two blades, while a three-blade fan has three blades.
2.Functions and usage
There are also differences in functions and usage between two-blade fans and three-blade fans. Double-blade fans are suitable for situations where the air volume is small, such as ventilation, cooling and heat dissipation. The three-blade fan is suitable for situations with large air volume, such as air conditioning and refrigeration, generator cooling, factory workshops, etc.
3.Noise and vibration
Two-blade fans have less noise and vibration than three-blade fans. However, when running at high speed, the double-blade fan is prone to instability, which affects its service life.
4.Efficiency
Due to the structural characteristics of the three-blade fan, it can better adapt to high-speed movement and has a larger flow rate, so it is highly efficient. The double-blade fan performs better at low speeds, but its efficiency gradually decreases at high speeds.

Advantages and Disadvantages of Two-Blade Fans and Three-Blade Fans

1.Advantages and disadvantages of double blade fan
Double-blade fans have smaller power consumption and lower prices, and are suitable for situations with small air volume and low power. At the same time, it is also easier to clean and maintain, so it is loved by many users. However, the noise and vibration of the double-blade fan are relatively large, and it is prone to instability at high speeds.
2.Advantages and disadvantages of three-blade fans
The three-blade fan has relatively high efficiency and is suitable for occasions with large air volume and high power. Because it has more blades, it can handle high-speed movements more easily. At the same time, the noise and vibration of the three-blade fan are smaller. However, due to its complex structure, maintenance and cleaning are difficult, and the price is relatively high.
