1, because conventional dynamic balance motor-driven variable valve adopts the high-drag stop valve to keep two ends pressure reduction,, increases pump energy consumption so obviously increase SR;
2, because valve adopts the self-operated type equilibrium principle, hydraulic equilibrium is to regulate according to the pressure reduction at valve two ends, need to adopt special-purpose regulating device in the adjustment process, and need the professional and technical personnel to debug, if but system changes, the difficulty that secondary is adjusted is bigger, and system is not easy permanent maintenance;
3, valve actuator mainly is to regulate aperture to use, and connection terminal relates generally to power supply, control signal, valve position feedback etc., does not have computing power, can't know information such as flow, energy;
4, valve does not have ability to communicate, when system needs secondary to regulate, can only regulate one by one, can not analysis system hydraulic equilibrium situation;
5, because hydraulic equilibrium partly adopts is self-operated type, the feedback information deficiency of valve, when valve went wrong aspect hydraulic equilibrium, system is feedback not fully.
