On be provided with oil level indicator, the oil-suction oil filter is connected with oil pump；The oil pump is electric with precise oil filter and AC servo respectively
Machine connects；The precise oil filter is connected with oil circuit reversal valve；The oil circuit reversal valve respectively with unloading valve, master cylinder, clamping
Reversal valve connects with pressure regulator valve；The clamping reversal valve is connected with clamping cylinder.As preferential technical scheme, in the fuel tank
It is provided with antiwear hydraulic oil.As preferential technical scheme, the oil pump motor is AC servo motor, and its rotating speed controls
Scope is 1:More than 500000.
(3) beneficial effect
Compared with prior art, it has the advantages that the utility model：The utility model electro-hydraulic servo control
System, debug and simple to operate, greatly improve control accuracy, noise can be controlled within 40 decibels, due to without using price
Higher hydraulic efficiency servo-valve, manufacturing cost reduces by 1/3rd, and solves the heating problem of hydraulic system, Energy in use
It is greatly reduced.
