Radio-hydraulic control technology

Radio-hydraulic control technology

Radio-electrohydraulic control technology combines the advantages of electro-hydraulic control technology and wireless communication technology, and can be widely used in fields such as engineering machinery. It not only improves the automation level and operability of engineering machinery, but also improves the working environment of operators and reduces operational errors caused by limited vision. It has been widely used in industries such as construction and mining in engineering machinery, accelerating the process of national industrialization. I. Basic Principles of Radio-Electrohydraulic Control Technology The basic working principle of radio-electrohydraulic control technology: First, the radio-electrohydraulic control system will allow operators or

Technical Development of Computer-Aided Hydraulic Integrated Block Design

Technical Development of Computer-Aided Hydraulic Integrated Block Design

Abstract: This article divides the technological development history of computer-aided hydraulic integrated block design software and discusses the technical characteristics of each development stage. In hydraulic system design, the integrated block is the main board that connects the channels or pipelines of various functional valve blocks of the system; it is not only a connection mapping of the hydraulic schematic diagram on the three-dimensional valve block, but also an expansion based on the installation conditions of the functional valve block and the manufacturing process of the integrated block; the design of the integrated block is an assembly design from known functional valve bodies, from the bottom up; the design not only considers the functional valve block on a certain surface of the integrated block

Reasons and solutions for poor hydraulic cylinder seal performance

Reasons and solutions for poor hydraulic cylinder seal performance

Everyone knows that after using a hydraulic cylinder for a period of time, the two most common undesirable phenomena are a decrease in operating speed and insufficient thrust. The main reasons for these two situations are as follows: 1. Excessive leakage of hydraulic oil inside the hydraulic cylinder. 2. The oil seal at the end of the hydraulic cylinder is pressed too tightly, but it is also possible that the piston rod has bent, resulting in a significant increase in resistance and friction. 3. The operator frequently uses only a certain section of the stroke when using the cylinder, leading to poor linearity of the cylinder, and in severe cases, causing damage to the hydraulic cylinder.
