X‑ray lead‑lined protective doors are specialised shielding assemblies built for hospital radiology departments as well as industrial non‑destructive inspection sites. A high‑purity lead sheet forms the primary radiation‑blocking core. Combined with smart drive hardware and comprehensive safety mechanisms, these units maintain strict radiation containment while delivering quiet, dependable access. All design outputs satisfy requirements laid out in GBZ 130‑2020 and other applicable industry specifications.
Radiation‑Shielding Performance
Lead equivalent rating: baseline ≥2 mmPb; custom shielding range: 1 mmPb ~ 6 mmPb
Radiation blocking efficiency: ≥99.9 % attenuation for medical‑grade X‑rays within 80‑150 kV tube voltage
Gap leakage mitigation: three‑stage labyrinth‑style joint design paired with lead‑silicide sealing gaskets; resultant leakage dose rate stays below 0.25 μSv/h
Structural materials: 1.5 mm cold‑rolled steel framework (SUS304 stainless steel as optional upgrade); internal cross‑grid reinforcing ribs; antibacterial surface coating survives more than 2000 cycles of alcohol‑based surface disinfection wiping.
Drive & Control Module
Motor unit: 24 V DC brushless motor, power output ranging 0.4‑0.75 kW; A‑weighted sound level ≤45 dB
Adjustable motion profile: infinitely variable travel speed from 10 cm/s up to 20 cm/s; soft start‑stop cushioning distance limited within 2 cm
Equipment interlock capability: DICOM‑protocol compatible linkage with radiology devices. The door will auto‑lock once X‑ray emission is triggered.
Active Anti‑Trapping Protection
Dual‑sided 8‑beam infrared light‑barrier sensor, detection coverage height spans 5 cm‑180 cm, system response＜0.1 seconds
Flexible bottom‑mounted pressure‑sensing safety edge: instant door‑reversal upon contact force reaching ≤5 kg
Emergency Handling Functions
Manual unlatching force ≤100 N for power‑out scenarios; mechanical emergency pull rod included as standard configuration
On‑board fault‑diagnosis chip; LED display outputs fault codes E01‑E20 for fast field troubleshooting
Custom‑Built Configuration Choices
Opening dimension scope: fits rough openings measuring 0.9 m × 2.1 m through to 2.4 m × 2.8 m; out‑of‑range non‑standard dimensions are acceptable upon request
Opening mechanism types: recessed‑track sliding door; 90‑degree hinged swing door furnished with air‑seal hinges
Optional add‑on components: lead‑glass viewing window (≥8 mmPb shielding rating), access‑control kit, UV disinfection assembly
Certifications & After‑Sales Services
Qualification documents: Class‑II medical device registration, radiation safety permit, CE EN61331‑1 compliance certification
Endurance validation data: After completing 100 000 open‑close durability cycles, variation of lead‑shielding attenuation remains less than 3 %; track abrasion wear ≤0.2 mm
Warranty & inspection terms: major functional components carry a 3‑year manufacturer warranty. Quarterly radiation‑dose inspection service is available, complying with JJG 774‑2022 metrology standards.
