Single Slider Vacuum Pumps Design & Development
The structure of the single slider vacuum pump is simple and cost-effective, capable of meeting the requirements for medium vacuum applications (with an absolute vacuum degree not
exceeding 10Pa), such as pneumatic systems like brake boosters in automobiles. APT's proprietary technology allows for the customization of high performance, high reliability,
lower NVH, and lower power consumption for customers' specific applications.
The geometric profile of the working surface of the pump body chamber fully constrains the motion characteristics and dynamic behavior of the blade. It dictates the rate of volume
change in the suction chamber, the contact stress and speed rate between the slider and the chamber, the speed rate between the slider and the slide groove, as well as critical
parameters such as the curvature of the sealing interface. Consequently, these factors determine the performance and reliability metrics of the vacuum pump.
Differing from the commonly used helical-type profiles in the industry, APT utilizes various novel stator profile curves solved through the Real Motion® algorithm. This enables
a more precise definition and control of slider motion characteristics. Depending on specific technical requirements and operating conditions, one can choose a particular chamber
profile and further perform multi-parameter optimization to achieve the optimization of suction-discharge characteristics, friction wear, vibration noise, and component lifespan.

- Lubrication and air circuit control technology
APT's proprietary technology quantifies lubricating oil supply, optimizes the lubrication of bearings and slider, and improves gap sealing to ensure stable operation of all
friction pairs. Significant enhancements in suction efficiency are achieved through phase optimization of the intake and exhaust channels, along with the parameter optimization
of check valve.
- Motion and performance simulation analysis
APT's algorithms and design software can real-time simulate the motion parameters and performance parameters of components, as well as conduct vacuum performance analysis and BENCHMARK
analysis for the entire assembly. These analyses are synchronized with the design process, facilitating rapid iterations to achieve optimal solutions.
