Embodiment 1

[0019] A new type of linear reciprocating hydraulic cylinder, which has a cylinder barrel 1, a cylinder head 2 and a piston 3, the outer surface of the cylinder barrel 1 is sprayed with an anti-corrosion layer 4, the cylinder barrel 1 is provided with a cylinder head 2, and the outer diameter of the piston 3 is A sealing ring 5 is arranged on it.

Embodiment 2

[0021] Example 2 as figure 1 As shown, it is improved on the basis of Embodiment 1. There is an oil drain hole 6 on its cylinder barrel 1. When the hydraulic cylinder moves to the end of the stroke, it has relatively large kinetic energy. If no deceleration treatment is performed, the hydraulic cylinder piston and cylinder The cover will be mechanically collided, resulting in impact, noise, and destructive. The drain hole is safely treated to meet this requirement.

Embodiment 3

[0023] Example 3 as figure 1 As shown, it is improved on the basis of Embodiment 1. Its piston 3 is provided with a relief valve 7, and the piston plays the role of suppressing oil and power conversion. Sometimes the oil pressure is too large, and the relief valve is required to adjust the pressure. , to prevent the piston from being crushed and deformed. The relief valve acts as a safety back pressure. Relief valves are essential, not only for problems that arise, but also to provide a safe working environment for hydraulic cylinders.

Abstract

The invention discloses a novel linear reciprocating motion type hydraulic cylinder. The novel linear reciprocating motion type hydraulic cylinder comprises a cylinder barrel 1, a cylinder cover 2 and a piston 3, wherein an anti-corrosion coating 4 is sprayed on the outer surface of the cylinder barrel 1; the cylinder cover 2 is arranged on the cylinder barrel 1; a sealing ring 5 is arranged on the outer diameter of the piston 3; an oil draining hole 6 is formed in the cylinder barrel 1; an overflow valve 7 is arranged on the piston 3; a safety valve 8 is arranged on the cylinder cover 2; a spring 9 is arranged between the piston 3 and the cylinder barrel 1. The novel hydraulic cylinder is simple in structure and convenient to use, has better sealing performance, can eliminate a phenomenon of liquid leakage, works reliably and saves the cost, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to a novel hydraulic device which can reduce noise and improve the service life of the device, in particular to a novel linear reciprocating hydraulic cylinder. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into receiving and unloading energy and performs linear reciprocating motion. It has a 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. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it has been widely used in various mechanical hydrau...
