Operation method of two-stage buffer capable of controlling buffering sequence stage by stage

Abstract

The invention relates to an operation method of a two-stage buffer capable of controlling a buffering sequence stage by stage. The two-stage buffer comprises a first stage buffer part and a final stage buffer part, wherein each of the first stage buffer part and the final stage buffer part comprises a columniform cylinder body; cylinder covers are arranged at open ends of the cylinder bodies in a sealing manner; a piston rod is movably matched with a center through hole of each cylinder cover in a sealing manner; piston body components are arranged at the right ends of the piston rods; the piston body components can make piston motion in the cylinder bodies, and are movably matched with inner walls of the cylinder bodies in a sealing manner; the cylinder body of the first stage buffer part forms the piston rod of the final stage buffer part; and pressure sensors for detecting medium pressures are arranged on the right end surfaces of the piston body components of the first stage buffer part and the final stage buffer part. The operation method of the two-stage buffer comprises the steps that the piston body components of both the buffer parts can adjust the medium traffic flows in the corresponding cylinder bodies according to the medium pressures detected by the pressure sensors to control the speed of the piston motion during the piston motion.

Description

technical field [0001] The invention relates to a buffer, in particular to a working method of a two-stage buffer using elastic colloid as a buffer medium. Background technique [0002] In the field of cushioning and shock absorption, buffers are widely used, and their main functions are to absorb various impact energy, protect equipment and reduce noise. [0003] The authorization number CN 202149175 discloses a buffer, which is a two-stage buffer, through the difference of the medium maximum force F1max and the initial minimum force F2cmin in the primary buffer and the secondary buffer, to control the primary buffer, secondary buffer The order of action of the first-stage buffer; and it is mentioned in the specification that the capacity of the entire buffer is set according to the impact energy, but in real work, because the impact energy is not constant, there may be changes, so it depends on the medium To realize the working order of buffers at all levels, it is diffic...
