What are hydraulic parts


Hydraulic accessories are composed of many parts, and the inherent reliability depends on the reliability of each part, especially the reliability of some key components. Therefore, the quality of the materials, design, processing, and assembly methods used for each component, as well as the performance and failure mode of each component. Life characteristics, reliability levels, and mutual cooperation effects all directly affect the reliability indicators of components. Similarly, a hydraulic system is composed of several hydraulic components, and its inherent reliability also depends on the reliability of each component and the combination of components, that is, the design of the system. For a newly designed element or system, reliability should be used to guide the overall plan at the beginning of the design, and the reliability design method should be used to design each component, so that the design object has high inherent reliability in the theoretical soil, and then Try to ensure that the design goals are achieved during processing and assembly, and finally obtain products with high inherent reliability. For existing products, to improve their inherent reliability, we must first analyze and study the main factors affecting product life and reliability, and then use reliability design methods and take reasonable measures to improve the product.

It can be seen that in order to improve the stability of products, reliability design methods must be adopted, and reasonable use of reliability design methods will surely ensure that products have high inherent reliability. Of course, the premise is that the production process ensures various design indicators, that is, the parts meet the design accuracy, and the indicators of each process meet the design requirements.

Reliability design, as a probabilistic design method, is a relatively new field, especially in hydraulic technology. Reliability design is still at the stage of theoretical and practical exploration. Subjectively, the majority of designers still lack the knowledge of reliability design theory. Objectively, there is not yet complete design data for reliability design (such as the probability distribution of the strength of the material used, the probability distribution of the stress of the mold part when the component is working, etc.). Even the failure modes and mechanisms of various hydraulic components. All are still under discussion and research. However, with the improvement of product reliability requirements and the development of corresponding industrial sectors, it is imperative to adopt reliability design methods for the design of hydraulic components and systems.
