Gas valve technology

Reed valves and sheet valves remain the research topics of many compressor technicians, indicating that after 40 years of research using modern instruments and analyses, a method for designing fault-free valves has not yet been found. The current research on gas valves mainly includes: flow analysis around the gas valve and the study of pressure loss affecting the performance of the compressor.

Airflow pulsation

Airflow pulsation is an important compressor technology. In the airflow pulsation, a simulator was adopted to calculate the natural frequency of the air column, pulsating pressure, resulting vibration, and the natural frequency of the complex pipeline system, as well as analyze the dynamic response, making the pipeline system design reasonable and the vibration damping measures effective.

Compressor frequency

At present, the research on compressor technology mainly focuses on two aspects: enhancing the lifespan and efficiency of products. Research aimed at enhancing the efficiency of compressors involves two scenarios: one is to optimize the internal factors of the compressor, and the other is to modify the structure of the compressor. For the former, the first step is to analyze the performance of the compressor, which is divided into items such as pressure loss, leakage loss, mechanical loss and motor loss, and adopt an optimization method for its influencing factors. For the latter, within the capacity range between rotary compressors and screw compressors, the transition from the traditional reciprocating type to the vortex type is an example.

Vibration and noise

Reducing the noise of compressors has always been a compressor technology of great value. Many articles on the geometry of turbine casings, vibration and sound radiation, electromagnetic noise, cavitation connection pipes, and airflow pulsation in silencing devices are all related to noise control.
