Abstract

The invention discloses a multiple-cavity high thrust energy-saving oil cylinder which comprises a cylinder body, a cylinder head, an end cap, a piston rod and a control valve set. The cylinder head and the end cap are arranged at the two ends of the cylinder body, a piston doing reciprocated movement along an inner cavity of the cylinder body is arranged at the middle portion of the piston rod, a cylinder bottom is fixedly arranged outside the end cap, and a pressurization cavity is formed between the cylinder bottom and the end cap; the piston rod penetrates the cylinder head and the cylinder body and extends out the end cap to be located in the pressurization cavity, a pressurization opening is formed in the cylinder bottom, and a hydraulic oil way is connected to the pressurization opening through a pipe. The pressurization cavity is arranged on the multiple-cavity high thrust energy-saving oil cylinder, and therefore pushing force during starting is increased, and the aim of reciprocating motion of the piston rod at a constant speed is guaranteed; and under the condition of the same pushing force requirement, a small-specification oil cylinder can be selected for achieving the aim. Energy consumption is reduced, the manufacturing cost is reduced, and on-site installation space is saved.

Description

technical field [0001] The invention relates to a vibration cylinder, in particular to a multi-chamber high-thrust energy-saving oil cylinder. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides. [0003] Therefore, in the existing technology, it is necessary to increase the thrust of the hydraulic cylinder, and most of them adopt to increase the effective area of ​​the piston, which inevitably results in a larger volume of the overall hydraulic...
