This 3T servo press for leak testing is a high-precision integrated solution designed for the precision packaging and testing of ion exchange membrane modules or cell stack units, the core components of liquid flow batteries.
It provides a stable press force of up to 3 tons to ensure uniform force and tight fit of membrane electrodes and flow field plates and other components during the assembly process. The equipment adopts full closed-loop servo control and millisecond pressure feedback system, which can control the press-fitting process with micron-level precision, effectively avoiding damage to sensitive and fragile membrane materials and sealing structures due to pressure or displacement deviation.
PRODUCT DESCRIPTION
Technical Highlights
1. Precision Servo Pressing System
●Constant Force Control: Driven by a servo motor and high-precision ball screw, the system enables closed-loop control of pressing force and position. It simulates stack assembly torque and end plate pressure based on preset programs.
●Anti-Offset Guide Design: A rigid four-column guide structure ensures parallel platen movement, protecting the stack from uneven stress.
●Stepless Pressure Adjustment: Infinitely adjustable pressing force adapts to stacks of varying sizes and cell counts.
2. High-Accuracy Leak Detection
●Dual-Mode Testing: Supports differential pressure testing for high sensitivity to micro-leaks and direct pressure testing for fast, large-volume applications.
●Multi-Channel Independent Control: Enables separate gas charging and leak detection for positive, negative, and external sides of flow battery stacks, precisely identifying leak paths.
●Corrosion-Resistant Pneumatics: Key components are corrosion-protected to withstand residual electrolyte vapor when using compressed air or nitrogen.
3. Intelligent Operation & Full Traceability
●Touchscreen + PLC: User-friendly HMI for one-click start after setting pressure, dwell time, and leak rate limits.
●MES Integration: Built-in barcode scanner links test results to the stack ID, enabling real-time data uploads and "one stack, one file" traceability.
●Auto Pass/Fail: Visual and audible alarms instantly alert operators, and failed units are locked out to prevent further processing.
Typical Applications
●R&D Labs: Seal performance testing of new materials (membranes, bipolar plates) for all-vanadium, iron-chromium, and zinc-bromine flow batteries.
●Process Development: Validation of seal bead designs and gasket performance (e.g., EPDM, Viton) under various compression ratios.
●Incoming QC: Leak testing of bipolar plates and end plates to verify flatness and seal groove integrity.
●Pre-Shipment Sampling: Final leak checks for small assembled stacks prior to delivery.
