In recent years, ultrasonic cleaning technology has been widely used in industrial fields such as automotive manufacturing, aerospace, electronic semiconductors, and optical precision manufacturing, relying on the micro cleaning ability of cavitation effect. It gradually replaces traditional manual or spray cleaning methods, effectively solves the cleaning problems of complex structural components, and helps the manufacturing industry improve quality and efficiency, and reduce costs.In the field of automotive parts manufacturing, ultrasonic cleaning technology has become the core support for mass production. A certain German automotive parts supplier uses a five slot ultrasonic cleaning system to treat engine cylinder heads, achieving full process automation of "heavy oil cleaning → precision rinsing → spraying → rust prevention → drying", reducing residual oil from ≥ 15g/m ² to ≤ 0.5g/m ², significantly reducing the number of metal particles, achieving VDA19 standa...

When purchasing electric ball valves, only specifying the specifications, categories and working pressure to meet the purchasing requirements is not perfect in the current market economic environment. For the competition of products, the electric ball valve manufacturers carry out different innovations under the concept of unified design of electric ball valves, forming their own enterprise standards and product personality. Therefore, it is very necessary to put forward technical requirements in detail when purchasing electric ball valves, and coordinate with manufacturers to reach a consensus as an accessory of electric ball valve purchase contract.1. General requirements1.1 The specifications and categories of electric ball valves should meet the requirements of pipeline design documents.1.2 The model of the electric ball valve should indicate the requirements of the national standard number. If it is an enterprise standard, the relevant description of the model sho...
