The three blade Roots reciprocating unit is a composite equipment that combines Roots blower and reciprocating machinery. Its working principle and characteristics are as follows:
1、 Working principle
1. Roots blower section: Two three bladed rotors rotate synchronously in reverse within an elliptical casing, utilizing volume changes to forcibly transport gas. There is a small gap between the rotors, and the gas is sucked in from the inlet and compressed before being discharged from the outlet, forming a continuous airflow.
2. The reciprocating unit section usually adopts a piston structure, which converts rotational motion into linear motion through a crankshaft connecting rod mechanism to achieve gas compression and transportation. The combination of the two can adapt to higher pressure or more complex working conditions.
2、 Core Features
1. Efficient and stable: The three leaf Roots section has high volumetric efficiency, and the flow rate is proportional to the rotational speed. Pressure fluctuations have little impact on the flow rate; The reciprocating unit can provide a higher compression ratio to meet high-pressure requirements.
2. Low noise and low vibration: The three bladed rotor design significantly reduces airflow pulsation, and further reduces noise when combined with a muffler; The reciprocating unit optimizes vibration control through a balancing mechanism.
3. Strong adaptability: It can transport clean air, corrosive gases (such as chlorine and hydrogen), and particulate materials, and special materials expand its application scenarios.
4. Easy maintenance: no contact wear on the rotor, long bearing life; The modular design of reciprocating units facilitates maintenance and replacement of vulnerable parts.
5. Energy saving advantages: The three leaf section has low energy consumption, and the reciprocating unit optimizes energy efficiency through multi-stage compression, resulting in significant long-term cost-effectiveness.
3、 Typical applications
1. High pressure gas transportation: such as chlorine gas compression and hydrogen gas recovery in the chemical industry.
2. Complex operating system: It needs to meet both high flow and high pressure scenarios, such as large-scale sewage treatment aeration systems.
3. Special material conveying: pneumatic conveying containing corrosive or flammable and explosive media.
The unit has achieved a wider range of applications and higher operational reliability by integrating the advantages of two types of machinery.
