Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1, the bender hydraulic synchronous system that a kind of hydraulic synchronous motor controls, comprise fuel tank 1, inlet oil filter 2, oil hydraulic pump 3, return filter 4, one-way valve 5, pressure meter switch 6, pressure gauge 7, relief valve 8, one-way speed-regulating valve 9, three-position four-way electromagnetic directional valve 10, hydraulic synchronous motor 11, first oil hydraulic cylinder 121, second oil hydraulic cylinder 122.
In bender working procedure, oil hydraulic pump 3 is by the hydraulic oil sucking-off in fuel tank 1, and the oil outlet through oil hydraulic pump 3 enters one-way valve 5, is divided into two oil circuits through one-way valve 5, and wherein fuel tank 1 is got back to through relief valve 8, return filter 4 in a road; Another road binders road enters three-position four-way electromagnetic directional valve 10 through inlet oil filter 2, shunts the rodless cavity entering the first oil hydraulic cylinder 121 and the second oil hydraulic cylinder 122 respectively through hydraulic synchronous motor 11; Hydraulic oil flows out from the rod chamber of the first oil hydraulic cylinder 121 and the second oil hydraulic cylinder 122, is connected the return line of relief valve 8, returns fuel tank 1 through return filter 4 through one-way speed-regulating valve 9 with three-position four-way electromagnetic directional valve 10; One-way valve 5 damages oil hydraulic pump 3 in order to prevent hydraulic oil from flowing backwards; Pressure meter switch 6, pressure gauge 7 are in order to monitoring system pressure; Return filter 4, with bypass, bypass has a cracking pressure be the one-way valve of 0.3 MPa; The filter core grade of inlet oil filter 2 and return filter 4 is 10 μm; The structure of the first oil hydraulic cylinder 121 and the second oil hydraulic cylinder 122, size, precision, volumetric efficiency are identical.
