Product Overview

Core Product Competitive Advantages

1. Stable AC‑Driven Cam‑Mechanism for Reproducible Oscillation Motion
   Precision AC motor drives cam‑shaft assembly, strictly implementing 20 mm free‑fall drop height and 100 r/min cyclic frequency. The heavy‑weight vibration box (over 10 kg) delivers authentic mechanical shock effect as defined in international respirator‑test norms, securing excellent inter‑batch repeatability for pretreatment results.
2. 32‑Bit ARM Micro‑Controller & Intuitive Colour Touch‑Screen HMI
   High‑performance 32‑bit ARM processor executes closed‑loop logic for timing and cycle‑counting. Colour touch‑screen offers straightforward parameter setup. Two independent working logics are selectable: time‑based countdown mode and cycle‑count‑based mode. Both ascending‑count and descending‑count display options are available to adapt varied laboratory‑operating habits.
3. Robust Multi‑Compartment SUS304 Stainless‑Steel Vibration Box
   The sample‑holding bin adopts full stainless‑steel construction with divided internal compartments. Multiple filter‑element specimens can be loaded simultaneously while preventing mutual collision during oscillation cycles. Solid welding craftsmanship resists repeated mechanical‑shock fatigue for long‑term workshop‑lab service life.
4. Separated Modular Layout of Vibration Base and Control Cabinet
   The unit is split into two standalone assemblies: mechanical vibration base unit and vertical touch‑screen control stand. This modular layout reduces vibration transfer toward electronic control components, protecting touch‑screen and internal circuit boards from continuous mechanical‑shock. Adjustable anti‑vibration foot pads ensure horizontal installation on uneven lab‑floor surfaces.
5. Automatic Test Termination & Status‑Indication Function
   Once preset oscillation duration or target cycle‑number is achieved, the instrument automatically halts motor rotation. Operators can directly read completed test‑parameters from screen without manual stop‑watch recording, minimising human‑caused operational errors during lengthy pretreatment workflows.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation
   Place vibration base and control cabinet on solid horizontal lab‑floor, adjust anti‑vibration foot‑pads for full levelling. Connect signal‑cable between two units and switch‑on AC power‑supply. Inspect vibration box interior, remove foreign debris. Prepare respirator filter‑element specimens to be pre‑conditioned. Enter target parameters on touch‑screen: choose timing‑mode or counting‑mode, set test duration / total oscillation‑cycles.
2. Specimen Loading
   Open the top of stainless‑steel vibration box. Place filter‑element samples separately into divided compartments. Ensure individual specimens retain proper clearance and will not collide against each other during drop‑oscillation cycles. Close vibration‑box lid securely.
3. Start Mechanical Oscillation Pretreatment
   Trigger test‑start command. Cam‑drive mechanism lifts the vibration box and releases it for free‑fall repetitively. Touch‑screen displays real‑time elapsed‑time or remaining‑cycle‑count throughout running‑process.
4. Automatic Completion & Specimen Retrieval
   When pre‑defined time or cycle‑threshold is reached, equipment stops oscillation automatically. Open vibration‑box, take‑out all pre‑treated filter‑element specimens. Carry‑out visual inspection for cracks, detachment and mechanical damage, then proceed with subsequent filtration‑efficiency and breathing‑resistance performance‑tests.
5. Post‑Test Tidying
   Clear fragments and residues from inside vibration‑box. Shut‑down instrument power‑supply. Periodically inspect cam‑drive components, fastener tightness and touch‑screen signal‑connection status for preventive‑maintenance.
