AI Technical Summary
Existing screw compressor slide valve mechanisms suffer from problems such as redundant and complex structure, unreliable sealing, poor motion stability, large space occupation, and serious noise pollution, making it difficult to meet the requirements of high efficiency, compactness, and long service life.
The externally suspended hydraulic cylinder is eliminated, and an integrated design is adopted to integrate the hydraulic cylinder and volumetric flow slide valve structure inside the compressor. The movement of the slide valve is controlled by a three-position four-way reversing valve, which simplifies the structure, reduces dynamic seals, and improves coaxiality and sealing reliability.
It achieves the miniaturization and integration of compressors, avoids oil leakage, improves the adjustment accuracy and operational stability of slide valves, reduces equipment vibration and noise, extends service life, and adapts to the industry's demand for efficient and compact development.
