Hydraulic cylinder for high-speed and high-temperature environment

Abstract

The hydraulic cylinder for the high-speed and high-temperature environment comprises a hydraulic cylinder body, a telescopic rod is arranged on the hydraulic cylinder body, the hydraulic cylinder body is arranged in a high-temperature working chamber, and the telescopic rod slidably penetrates out of the high-temperature working chamber; a high-speed buffer structure is arranged at the bottom end of the hydraulic cylinder body, penetrates out of the high-temperature working chamber and is connected with a piston barrel, one side of the piston barrel is connected with a water supply assembly, the other side of the piston barrel is connected with a water outlet assembly, the water outlet assembly is communicated with the high-temperature working chamber, and the high-temperature working chamber is further connected with an exhaust assembly. And the high-temperature working chamber and the piston cylinder are arranged on the bracket. According to the hydraulic cylinder for the high-speed and high-temperature environment, an existing hydraulic cylinder system can adapt to the high-speed and high-temperature environment, the working life of the hydraulic cylinder is greatly prolonged through the combined action of the high-speed buffering structure, the piston barrel and the cooling system, and the hydraulic cylinder has the advantages of being high in high-temperature resistance, reliable in work and good in buffering performance.

Description

technical field

[0001] The invention belongs to the technical field of hydraulic cylinders, and in particular relates to a hydraulic cylinder for high-speed and high-temperature environments. Background technique

[0002] The movement speed of the high-speed hydraulic cylinder piston is very high, which will produce strong impact, collision and vibration at the end of the piston stroke, resulting in damage to parts, and proper buffer braking must be carried out. At present, there are two main ways of buffering of hydraulic cylinders: one is external buffering of hydraulic cylinder, that is, adding a throttle control device to the control circuit of hydraulic cylinder to buffer by changing the throttling area; the other is internal buffering of hydraulic cylinder, that is A buffer structure is arranged inside the hydraulic cylinder for buffering, which has the advantages of simple structure, reliable operation and good buffering performance.

[0003] In addition, with the co...
