Abstract

A hydraulic cylinder is a volumetric hydraulic motor that converts the energy of the fluid flow into various types of movement of the output link. The use of volumetric hydraulic drives with a hydraulic cylinder working element in all possible fields of industry does not require high capacities. One of the advantages is the ease of operation and overload protection. There are also disadvantages. For example, the hydraulic cylinder depends on the working fluid and in case of contamination it may fail, and therefore the reliability of the hydraulic cylinder decreases. In order to protect hydraulic cylinders from moisture and dirt entering them, as well as to increase their reliability, seals with dirt-removing rings are provided. When assembling or disassembling hydraulic cylinders, important conditions must be taken into account, since failure to comply with these conditions can lead to a defect. Considerable efforts have been made to the parts, so some manual operations are excluded when assembling and disassembling hydraulic cylinders. The reliability of the hydraulic cylinder and, consequently, its reliability are the main topic of the study. Hydraulic cylinders can be of translational action and rotary action. Translational ones include: piston, plunger, telescopic. Reciprocating, in turn, can be one-sided and two-sided. If it is required to create an effort in only one direction, a one-way hydraulic cylinder is designed. At the beginning of the work, a diagram of a volumetric hydraulic drive and its principle of operation is presented. Special attention is paid to assessing the reliability of the hydraulic cylinder. In conclusion, the results of the analyses and the conclusions of the calculations are given. The change in the reliability of the hydraulic cylinder over time was also indicated and the reasons for this change were named. Keywords: Reliability, hydraulic cylinder, hydraulic drive, failure, reliability assessment, pipeline, pump, valve, operating time, hydraulic distributor.

双向液压缸的可靠性

液压缸是一种容积式液压马达，它将流体流动的能量转化为输出环节的各种类型的运动。在所有可能的工业领域中，使用带有液压缸工作元件的容积式液压驱动器不需要高容量。其优点之一是易于操作和过载保护。也有缺点。例如，液压缸依赖于工作流体，如果受到污染，它可能会失效，因此液压缸的可靠性降低。为了保护液压缸不受湿气和污垢的影响，并提高液压缸的可靠性，液压缸采用了带去污环的密封。在组装或拆卸液压缸时，必须考虑到重要的条件，因为不遵守这些条件可能导致缺陷。由于对零件做了相当大的努力，所以在拆装液压缸时，排除了一些人工操作。液压缸的可靠性是本文研究的主要内容。液压缸可以是平移动作和旋转动作。平移式包括:活塞式、柱塞式、伸缩式。反过来，往复可以是单方面的，也可以是双面的。如果只要求在一个方向上产生作用力，则设计单向液压缸。本文首先给出了容积式液压传动的原理图及其工作原理。对液压缸的可靠性进行了评估。最后，给出了分析结果和计算结论。还指出了液压缸可靠性随时间的变化，并指出了这种变化的原因。关键词:可靠性，液压缸，液压传动，故障，可靠性评估，管道，泵，阀，操作时间，液压分配器。
