Abstract

Electro hydraulic proportional pressure-flow compound valve (P-Q valve) is a new type of energy saving combination valve. The velocity and output force of the actuator can be proportionally controlled by the P-Q valve in different working state. The author puts forward a new scheme that the hydraulic elevator applies the P-Q valve to hydraulic driving control system. The author also makes theoretic analysis and builds a model of the elevator mechanical drive system and hydraulic driving system, according to which the system is simulated by computer. The results show that: the hydraulic driving control system which is based on P-Q valve of the hydraulic elevator has the advantage of smooth starting, high control precision and small impact in the case of emergency stop.
