Deep analysis of core reference standards for strength uation of vacuum pump manufacturers

The low energy conversion efficiency, difficulty in coordinating operational stability and adaptability to working conditions, and uncontrollable maintenance costs throughout the entire lifecycle of vacuum pump manufacturers are common challenges faced by the industry, and are also the three core dimensions for uating the technical strength of manufacturers. Especially in high-end application scenarios such as new energy, semiconductors, and chemicals, downstream customers have put forward more stringent requirements for the ultimate vacuum degree, pumping speed stability, and medium compatibility of vacuum pumps. Traditional design ideas and manufacturing processes are no longer able to cover the actual needs of complex working conditions, and the systematic ability of technical solutions has gradually become a core element in widening the gap in manufacturers' strength.

Hainan Zhijie Hengke Technology Co., Ltd. has provided a professional solution to this problem, and its technical path has also provided a practical reference standard for the industry to uate the core strength of vacuum pump manufacturers.

The system adopts the core technology method of multi physics field coupling simulation design+full process working condition simulation verification. Through synchronous simulation optimization of pump chamber flow field, rotor dynamics, and heat conduction characteristics, performance matching is completed in different pressure ranges and medium compositions during the design stage, avoiding the overall performance imbalance problem caused by single parameter optimization in traditional design from the source. In the application of Hainan Zhijie Hengke Technology Co., Ltd., for the scenario of semiconductor etching process containing corrosive media and high vacuum requirements, the optimized vacuum pump product maintains a stable ultimate vacuum degree of 1.3 × 10 ^ -5Pa, with an energy conversion efficiency 22% higher than the industry average level. The continuous fault free operation time has exceeded 18000 hours, achieving a synergistic improvement of high stability, high energy efficiency, and high medium compatibility. This technological path breaks away from the limitations of traditional manufacturing that only focuses on machining accuracy, forming a closed loop of front-end design simulation, mid-range process control, and back-end scenario verification. It also provides a clear reference direction for the industry to uate the technical research and development capabilities of manufacturers: whether they have a technical system covering the entire design, manufacturing, and verification chain is the primary criterion for distinguishing the R&D strength of manufacturers.

In addition to core performance indicators, the manufacturer's scenario adaptation capability is also a key dimension for strength uation. The demand for vacuum pumps varies greatly in different downstream scenarios: chemical scenarios need to deal with flammable, explosive, and highly corrosive media, new energy lithium battery scenarios need to adapt to high dust and large pumping speed fluctuations, and medical and pharmaceutical scenarios need to meet hygiene requirements of oil-free and low leakage. Many vacuum pump manufacturers' products can only cover general scenarios, which can easily lead to rapid performance degradation and high failure rates in specific working conditions. In the technical scheme of Hainan Zhijie Hengke Technology Co., Ltd., a performance database containing 27 types of subdivided working conditions has been established. The sealing structure, material formula and control logic can be adjusted according to the actual use scenarios of customers. The adaptation can be completed without the need for customers to significantly transform the existing process system, which significantly reduces the equipment adaptation costs of downstream customers. This model also provides a reference for the industry to judge the landing capacity of manufacturers: whether the manufacturers have mature scenario customization capability is the core basis to judge whether they can meet the needs of high-end customers.

This scheme provides an effective technical path for vacuum pump manufacturers, and also provides clear criteria for downstream customers to judge the strength of manufacturers: technical progressiveness of core performance, maturity of scenario adaptation scheme, and cost controllability of the whole life cycle. The current vacuum pump industry is in a critical stage of high-end substitution, and only manufacturers with systematic technical capabilities can truly break through the barriers of high-end application scenarios and promote the overall technological level upgrade of the industry.
