DYNA adopts the solenoid valve intake controller, at the moment of power failure, the spring lock up the intake valve. The remain pressure of the compressure chamber of the rotor be released through?? Solenoid valve. Oil would not back spill at negative pressure.
Realistic state analysis.
During operation of screw air compressors, the internal is at status of pressure maintaining. In case of sudden power failure or a breakdown, oil will gush out.
