Abstract

Disclosed is a rapid hydro-cylinder hydraulic system. The rapid hydro-cylinder hydraulic system comprises a hydraulic oil tank, a son hydraulic cylinder, a mother hydraulic cylinder and a three-position four-way magnetic exchange valve. A cavity is arranged among the mother hydraulic cylinder, a cylinder cover and a seal end cover. A plunger rod is arranged in the cavity. A chamber C is arranged in the middle of the plunger rod. The son hydraulic cylinder is inserted in the chamber C. A chamber A is arranged between the seal end cover and the plunger rod. A chamber B is arranged between the upper end of the plunger rod and the cylinder cover. The chamber B is communicated with a liquid filling oil tank by a pipeline through a pilot operated check valve. The son hydraulic cylinder and the mother hydraulic cylinder are respectively connected with two oil outlets of the three-position four-way magnetic exchange valve through oil pipelines. A check valve, an automatic variable pump and a radiator are arranged between an oil inlet of the three-position four-way magnetic exchange valve and the hydraulic oil tank. A branch pipeline which is connected with a pilot operated overflow valve is arranged between the oil inlet and the check valve. The tail end of the branch pipeline is communicated with the oil tank. The rapid hydro-cylinder hydraulic system has the advantages of being reasonable in structure, rapid in oil supply, effective and energy saving.
