Automatic Clamping Comprehensive Performance Test Bench For Water Ring Vacuum Pump Of Electric Vehicle

Automatic Clamping Comprehensive Performance Test Bench For Water Ring Vacuum Pump Of Electric Vehicle

Product Introduction

WPT-9 redefines the electric vehicle vacuum pump testing standard with automated clamping technology and full-condition simulation capabilities:

1. Automated clamping system

Quick positioning: The six-axis robotic arm (positioning accuracy ±0.1mm) cooperates with the visual recognition system to complete the automatic clamping of different types of vacuum pumps (horizontal/vertical) within 5 minutes, and is compatible with the G1/4"-G3/8" interface of mainstream brands (Bosch, Mahle, and United Electronics).

Adaptive sealing: Pneumatic elastic clamps (adjustable pressure 10-50kN) ensure zero leakage of flange/threaded interfaces, solve the problem of unstable sealing of manual clamping, and adapt to IP67/IP6K9K protection level vacuum pump testing.

2. Full performance testing capabilities

Vacuum performance:

Vacuum range 1-100kPa (accuracy ±0.1kPa), support maximum 80m³/h pumping rate test, and real-time drawing of vacuum-flow curve (ISO 28580 Clause 5.3 requirements).

The ultimate vacuum test (≤1kPa) and recovery time verification (vacuum drop rate after power failure ≤0.5kPa/s) simulate the emergency working conditions of the electric vehicle braking system.

Environmental adaptability:

The temperature control module supports -40℃ low temperature start-up and 125℃ high temperature endurance (accuracy ±1℃), with humidity adjustment (10%-95% RH), to verify the operating stability of the vacuum pump in the extreme environment of the battery compartment.

3. Intelligent measurement and control and data management

Operation interface: 12-inch industrial-grade touch screen (Chinese and English switch) with built-in 10+ test templates, one-click start of GB/T 32864 specified efficiency test, AEC-Q100 temperature cycle and other processes, parameter setting time shortened by 60%.

Data traceability: 256GB solid-state hard drive automatically records 50+ parameters such as vacuum, power consumption, vibration, etc., supports real-time acquisition of CAN/LIN bus data, and generates PDF reports that meet ISO 9001 requirements (including SPC process capability analysis).

4. Safety and reliability design

Hardware protection: Stainless steel test chamber (protection level IP67) with dual pressure sensors (primary and standby redundancy), automatic unloading of overpressure (110% set value), in line with IEC 60664-1 electrical safety standards.

Fault diagnosis: AI algorithm analyzes vibration spectrum in real time (resolution 0.1Hz), identifies 6 types of early failures such as impeller wear and bearing failure, with a diagnostic accuracy of >98%, and automatically triggers shutdown protection.
