LBT-ZM-820 Safety Helmet UV Aging Chamber

Description

Product Introduction

The safety helmet UV aging chamber is developed in accordance with GB/T 2812-2006 “Test Methods for Safety Helmets” and GB/T 2811-2019 “Safety Helmets,” and is specifically designed for pre‑treatment of safety helmets by UV irradiation. It is widely used in specialized labor protective equipment supervision and inspection stations, architectural research institutes, and construction engineering testing centers.

Reference standard:

GB/T 2812-2006 “Test Methods for Safety Helmets” and GB/T 2811-2019 “Safety Helmets”

Product Features:

Enclosure: The entire enclosure is constructed from cold-rolled steel sheet.

Temperature sensor: employs a high-precision PT100 temperature sensor.

Xenon Lamp: ★ Equipped with a 450W high‑pressure xenon lamp (our company’s xenon lamp was jointly developed in collaboration with a leading xenon lamp manufacturer; its radiant energy is identical to that of imported Osram xenon lamps, and its spectral curve closely matches Osram’s. The spectral peak attenuation is approximately 95% similar. Moreover, it is paired with a dedicated power supply and igniter, ensuring data stability.)

Internal Space: ★ The instrument features a unique internal design that makes efficient use of limited space, enabling simultaneous testing of 14 safety helmets over a 400-hour test period, thereby significantly saving time and costs.

Cooling System: ★ The instrument employs an integrated turbo‑fan air‑circulation system. Given the extended test duration of up to 400 hours, we have mounted the supply‑air turbine fan inside the electrical cabinet and use exhaust ventilation to cool the electrical components, significantly reducing component failure rates caused by heat generated by the electronics during testing. Additionally, the airflow is directed from the electrical cabinet—via the turbine fan—to the surface of the xenon lamp, ensuring a wind speed of 3 m/s around the lamp housing and preventing issues such as lamp rupture that could arise from an inadequately designed air‑circulation system.

Monitoring System: ★ The instrument is equipped with both an illuminance monitoring system and a light-sensor‑based monitoring system. The illuminance monitoring system continuously tracks light intensity, enabling timely replacement of the xenon lamp when its output drops to an ineffective level, thereby ensuring the validity of the test.

Light sensor: ★ If the xenon lamp shuts off unexpectedly during the test, the device will automatically stop timing and save the last recorded test duration; after replacing the xenon lamp, timing can resume.

Cooling method: Air-cooled. The instrument’s top is equipped with an advanced turbine‑type exhaust fan, which significantly increases airflow, operates at higher speeds, ensures stable performance, and is less prone to failure. With a bottom‑inlet, top‑outlet design, it maintains the internal temperature of the test chamber consistently below the 60°C limit specified in the standard.

Protection System: The equipment is equipped with an internal protection system that automatically shuts off all power to the experimental chamber in the event of a malfunction, ensuring the safety of both the equipment and the laboratory. The instrument also features a data‑saving function that can store the last recorded time.

Technical Specifications:

Ultraviolet light source: Uses a 450 W high‑pressure short‑pulse xenon lamp as specified in the standard.
Temperature sensor: Equipped with a high-precision temperature sensor, providing temperature measurement accuracy of 0.2%.
Temperature control system: employs a high-precision PID temperature control instrument; timing range: 0–999 hours; test time accuracy: 1 second.
Pre-processing quantity for safety helmets: 1–14 units
Experiment module temperature: <60℃
