AI Technical Summary
Existing reciprocating compressor cylinder clearance volume adjustment systems suffer from problems such as a single power source with no emergency backup, dual power sources lacking interlocking and prone to pressure surges, clearance maintenance without mechanical locking, poor dynamic response due to air in the hydraulic oil, and thermal drift caused by the thermal expansion and contraction of the oil.
It adopts a dual-power oil supply system, including a hydraulic pump and a manual pump, and achieves passive interlocking through a shuttle valve; a two-way hydraulic lock is added to automatically lock the position of the hydraulic baffle when the oil supply stops; an intelligent online venting component is set to separate the gas in the hydraulic oil; and a thermally compensated bypass piston is added to absorb the volume change of the oil due to thermal expansion and contraction.
It enables emergency operation protection in the event of power failure or malfunction, avoids clearance volume drift and response lag, improves system reliability and regulation stability, and ensures clearance control accuracy over a wide temperature range.
