At the beginning of the design of the control equipment, we need to conduct in-depth research on the characteristics of the control equipment, analyze the design parameters of the product, discuss and guarantee the performance and use conditions of the product, and develop a scientific and reasonable design scheme in this case. The structure and type of the product need to be designed according to the application space. The size of the product determines the type of product and its production scale and production volume.
The difference in the form and type of products also affects the economic performance of the product. These aspects need to be considered at the time of design, and any aspect missing will have some impact on the overall reliability of the equipment. In the case of ensuring the technical requirements of the device, the value engineering concept is adopted to select an economical and reasonable solution to design the parts to reduce the cost of the production products and reduce the manufacturing cost of the entire equipment. Choosing reasonable materials and components under careful thinking not only reduces the production cost, but also improves the practical performance and operation and maintenance performance of the product, and improves the reliability of the equipment as a whole.
Due to the large number of components in the equipment, it is necessary to be cautious when selecting components. The parts and components in the equipment should be as small as possible, and the general-purpose parts produced by professional manufacturers should be used as much as possible. This not only ensures the accuracy of the parts, but also guarantees the use performance, and can deal with the hardware problems of the equipment in time for maintenance and replacement. Strictly inspect at the time of purchase to prevent any leakage, and not to purchase economically poor materials due to vicious competition in the market.
How to choose components should be selected according to the technical conditions of the working environment, technical performance and quality level requirements of components. When selecting, the standard components are preferred, and there are enough substitutes to ensure timely replacement in case of failure. Due to the influence of temperature, the reliability of electronic equipment is directly related to the reliability of the entire equipment. Therefore, the selected electronic components have better heat dissipation performance, especially for electronic components with higher power, and heat dissipation must be good. At the same time, humidity also affects the reliability of electronic equipment. Especially in the environment of low temperature and high humidity, when the humidity of the air reaches saturation, the condensation of the components and printed circuit boards will cause the electrical performance of the electrical components to drop. In general, ensuring the reasonable selection of electronic components is one of the main methods to improve the reliability of electrical automation control equipment. |
