Core Product Competitive Advantages

1. Precision‑Machined Pneumatic‑Clamping Mechanical Assembly Pneumatic clamping structure delivers adjustable clamping pressure up to 5 kg/cm². Upper‑lower pressing‑ring concentricity is controlled below 0.25 mm, which effectively prevents specimen slippage during pressurisation and lowers system‑caused measuring deviation. Stable clamping performance guarantees repeatable test‑result consistency for batch‑sample testing.
2. High‑Speed Micro‑Processor Measuring & Control System High‑resolution pressure‑sensor paired with dedicated digital processing chip captures real‑time pressure‑change signals throughout the whole bursting cycle. 0.01 kg/cm² fine resolution captures the exact pressure moment when the sample ruptures. Built‑in power‑off memory function preserves completed test datasets in case of unexpected power interruption.
3. Intuitive Colour Touch‑Screen Human‑Machine Interface Touch‑screen panel supports multi‑unit switching including kg/cm² and KPa. Operators configure test parameters, view real‑time pressure values, check historical test records and execute data‑statistical computation directly on‑screen. Test indexes such as maximum burst‑pressure, minimum value and average value can be displayed in one interface.
4. Integrated Thermal‑Printing & PC‑Data‑Communication On‑board miniature thermal printer outputs complete test reports containing individual‑sample data and batch‑statistical results. It also supports external PC connection for further data archiving, sorting and report customisation. No extra complicated auxiliary equipment is required for on‑site quality‑control spot‑check tasks.
5. Mature Hydraulic‑Diaphragm System & Easy‑Maintenance Design Standard hydraulic medium is mixed liquid of 85 % glycerin plus 15 % distilled water. Interchangeable rubber‑diaphragm accessories with different convex‑height specifications are supplied to satisfy different‑material test requirements. Diaphragm‑replacement and routine‑calibration steps are clearly defined in the manual for lab‑staff daily maintenance. Compact bench‑top cabinet‑type layout occupies limited lab‑bench footprint.

Complete Technical Parameter Table

Rubber‑diaphragm reference parameter: 10 mm convex‑height diaphragm: resistance 170‑220 kPa; 18 mm convex‑height diaphragm: resistance 250‑350 kPa.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Check external air‑supply pressure status, confirm hydraulic‑liquid volume and inspect rubber‑diaphragm condition. Power‑on instrument, complete pre‑run self‑check, select corresponding test‑standard and set sample‑batch quantity parameters on touch‑screen.
2. Specimen Loading Cut test‑pieces to standard dimension, lay flat the specimen between upper‑lower clamping rings. Initiate clamping procedure to fix sample tightly and eliminate wrinkles.
3. Automatic Burst‑Strength Test Trigger test‑start command. Hydraulic system pressurises at preset flow‑rate. System continuously tracks pressure‑variation. Once specimen ruptures, the instrument instantly captures peak burst‑pressure value and automatically executes hydraulic‑cylinder return‑stroke.
4. Data Review & Report Output After test completion, view single‑sample reading or batch‑statistical results on touch‑screen. Users can choose to print inspection‑report locally or transmit datasets to computer terminal for long‑term filing.
5. Post‑Test Tidying Take‑away broken specimen. Clean debris on clamping‑ring surface. Shut‑down instrument after finishing all‑batch tests; cut‑off air‑source and main‑power supply. Carry‑out diaphragm‑resistance periodic‑calibration according to maintenance‑requirements.

Safety‑Operation‑Reminder

Confirm external air‑source pressure stays within the specified working‑range before testing. Periodically inspect rubber‑diaphragm performance and replace ageing diaphragm timely. Do not place hands near clamping‑ring zone during automatic‑testing cycles.
