The invention discloses a screw type hydraulic system. The screw type hydraulic system comprises a motor, a screw and a piston; a connecting plate is arranged on the top of the motor, a protection cylinder is arranged on the top of the connecting plate, the screw is arranged in the protection cylinder, a screw nut is arranged on the outer side of the screw, a piston rod is arranged on the top of the screw nut, a rear cavity is formed in the outer side of the piston rod, a rear oil outlet is formed in the outer side of the rear cavity, the piston is arranged on the top of the piston rod, an oil storage tank is arranged on the outer portion of the piston, a front cavity is formed in the inner side of the oil storage tank, and a front oil outlet is formed in the top of the front cavity; the manner that the screw is directly driven through the motor is adopted, the piston is directly driven to do reciprocated motion, hydraulic oil is pushed to enable a hydraulic execution element to work, the function of a common hydraulic system is achieved, use cost is reduced, meanwhile, the synchronous requirement of an execution element mounted at the same point can be perfectly executed, and use reliability is improved.
Description
technical field [0001] The invention relates to a hydraulic system, in particular to a screw type hydraulic system. Background technique [0002] As we all know, the traditional hydraulic system converts the pressure energy of the liquid into mechanical energy through the working medium, and drives the load for linear motion or rotary motion, which is widely used in various fields. The traditional hydraulic system is composed of motors, oil pumps, multiple hydraulic solenoid valves, oil circuit switching valve blocks, oil tanks, oil filters, pressure gauges and other components. Too many components cause high cost and high maintenance cost, and the For actuators installed in the same place, the synchronization requirements cannot be perfectly executed, and the reliability is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a screw-type hydraulic system, which can re...
