Overview

The Jianhu JH-10 Oscillating Pipe Rain Test Chamber is an engineered environmental simulation system designed to evaluate the ingress protection (IP) performance of electrical enclosures, outdoor equipment housings, automotive components, and industrial control panels against directed water exposure. It operates on the principle of controlled oscillatory water projection—where a precisely dimensioned stainless-steel pipe, fitted with uniformly spaced nozzles, sweeps across defined angular ranges while delivering calibrated water flow at regulated pressure. This replicates real-world rain conditions including light showers, heavy downpours, and lateral spray, enabling standardized assessment of sealing integrity, gasket effectiveness, and housing design robustness under dynamic wetting stress. The chamber conforms to the test requirements specified in GB 4208–1993 (equivalent to IEC 60529:1991 for IPX1 through IPX6 classifications), making it suitable for internal quality assurance labs, third-party testing facilities, and R&D centers validating product compliance prior to certification.

Key Features

• Two selectable oscillation radii (1.0 m and 0.6 m) to accommodate varying specimen sizes and test severity levels per GB 4208–1993 clauses.
• Precision-machined SUS304 stainless-steel oscillating pipe with 0.4 mm diameter nozzles spaced at 50 mm intervals—ensuring uniform droplet distribution and reproducible spray density.
• Adjustable oscillation angles (±180°, 120°, or quasi-360° continuous sweep) to simulate vertical rain, angled precipitation, and circumferential exposure scenarios.
• Independent frequency-controlled drives for both oscillation and turntable rotation—enabling precise, stepless speed regulation (1–17 rpm for turntable; variable oscillation frequency via inverter).
• Stainless-steel construction throughout all water-wetted surfaces—including inner/outer chambers, piping, nozzles, reservoir, and filtration system—to prevent corrosion and ensure long-term metrological stability.
• Integrated pressure regulation (80–150 kPa) with analog pressure gauge and inline flow meter for real-time hydraulic monitoring and repeatability verification.
• Modular control architecture featuring imported inverters for motion control and domestically sourced, UL-recognized electrical components meeting industrial safety standards.

Sample Compatibility & Compliance

The JH-10 accommodates specimens up to 800 mm in diameter on its motorized turntable, supporting upright, tilted, or rotating configurations during testing. Its mechanical layout permits evaluation of both stationary and rotating enclosures—critical for applications such as motor housings, junction boxes, and outdoor lighting fixtures. The system meets the physical configuration and operational criteria outlined in GB 4208–1993 for IPX1 (dripping water), IPX2 (tilted dripping), IPX3 (oscillating tube), IPX4 (splashing water), IPX5 (water jet), and IPX6 (powerful water jet). While not certified to ISO/IEC 17025, the chamber’s design supports traceable test execution when paired with calibrated pressure gauges, timers, and flow meters—facilitating documentation required for internal GLP-aligned validation protocols or pre-audit readiness for IP certification bodies.

Software & Data Management

The JH-10 operates via a hardwired industrial control panel with manual parameter setting—no embedded software or digital interface is included. All operational parameters (oscillation angle, pressure setpoint, turntable speed, and test duration) are configured using analog dials and push-button controls. Timing is managed by a dedicated mechanical or digital timer (user-selectable), with output signals capable of interfacing with external data loggers via dry-contact relay outputs. For laboratories requiring audit trails, users may integrate external USB-based pressure/flow data loggers compliant with FDA 21 CFR Part 11 guidelines—though native electronic recordkeeping is not provided. Calibration records for pressure transducers, flow meters, and timers should be maintained per organizational quality management system (QMS) requirements.

Applications

• Verification of IP rating claims for consumer electronics, industrial sensors, and telecom cabinets.
• Pre-certification testing for CE, CCC, and KC mark submissions where rain resistance is mandated.
• Design validation of ingress barriers in electric vehicle charging stations and battery enclosures.
• Reliability screening of outdoor LED luminaires, traffic signal housings, and solar inverter cabinets.
• Quality gate testing in final assembly lines for white goods and HVAC control units.
• Research into material wettability, sealant aging effects, and condensation mitigation strategies under cyclic wet-dry conditions.

FAQ

Does the JH-10 support automated test sequences or programmable profiles?

No—the system uses manual parameter adjustment via physical controls and does not include microprocessor-based sequencing logic.
Can the chamber be used for IPX7 or IPX8 testing?

No—submersion testing requires a separate immersion tank; the JH-10 is limited to oscillating pipe and spray methods per GB 4208–1993 Sections 13.2–13.4.
Is calibration documentation provided with shipment?

Factory calibration certificates for pressure and flow instrumentation are available upon request; field recalibration must be performed by accredited service providers.
What maintenance is required for long-term reliability?

Regular cleaning of stainless-steel nozzles and inline filters is recommended; periodic verification of inverter output stability and seal integrity of water joints is advised every 6 months.
Are replacement nozzles and SUS304 pipe sections available as spare parts?

Yes—Jianhu supplies OEM-specified nozzle arrays and pipe segments with documented dimensional tolerances and material certifications (EN 10088-1).
