Electric Vehicle Water Ring Vacuum Pump Automated Clamping Comprehensive Performance Test Bench

Product Introduction

• The WPT-9 Electric Vehicle Water Ring Vacuum Pump Automated Clamping Comprehensive Performance Test Bench is specialized testing equipment for core components of new energy vehicles, such as vacuum braking systems and air conditioning auxiliary pumps. It adopts a servo-driven automated clamping mechanism, completing positioning and fixing of the tested pump within 15 seconds. Equipped with a high-precision sensor set and intelligent control system, it synchronously collects 12 key parameters including vacuum level, flow rate, power, and temperature. Test data is uploaded to an industrial-grade database in real time, enabling traceability and analysis.
• Compared with traditional manual testing equipment, this test bench features "automated clamping + full-parameter closed-loop testing" as its core advantages. It reduces errors caused by manual intervention (test repeatability error ≤ 0.5%) and is compatible with water ring vacuum pumps of φ20-φ100mm caliber. It meets the efficient testing needs of mass production lines and helps enterprises improve product yield and R&D efficiency.

Product Features

• Fully automated process: Servo motor-driven clamping mechanism completes pump positioning, sealing, testing, and unloading with one click, reducing manual operations by 80% and minimizing human errors.
• High-precision testing capability: Adopts imported pressure sensors (0.1%FS accuracy) and electromagnetic flowmeters (±0.5% measurement error) to ensure accurate and reliable testing of vacuum degree, flow rate, and other parameters.
• Multi-parameter synchronous acquisition: Supports simultaneous monitoring of 12 parameters including vacuum degree, flow rate, rotational speed, power, and inlet-outlet temperature difference, with a sampling frequency of 1kHz to capture instantaneous performance fluctuations.
• Flexible compatibility design: Adaptable to water ring vacuum pumps with φ20-φ100mm calibers through adjustable tooling, compatible with customized pump models from different automakers without frequent fixture replacement.
• Intelligent data analysis: Equipped with industrial-grade testing software, it automatically generates data curves and qualification reports, supporting integration with MES systems to achieve closed-loop management of production data.
• Safety protection system: Equipped with overpressure protection, leakage protection, and emergency stop devices, compliant with ISO 13849-1 safety standards to ensure safe and stable testing processes.
