DESIGN AND FABRICATION OF A TOXIC GAS SUCTION PUMP FOR RAID-M100 AUTOMATIC CHEMICAL AGENT DETECTORS AND RAID-XP RADIATION MEASUREMENT DEVICES

Abstract

The RAID-M100 automatic chemical agent detector and the RAID-XP radiation measurement device require a stable and continuous gas flow to ensure the accuracy of the ion mobility spectrometry (IMS) analysis chamber. This paper presents the design and fabrication of a miniature toxic gas suction pump developed to meet the specific technical requirements of these two devices. The pump is designed with a high-sealing structure, low flow rate, and stable suction pressure, ensuring reliable gas sampling under continuous operating conditions. The study focuses on structural design, material selection, manufacturing processes, and performance evaluation through experimental testing. The results show that the pump achieves stable airflow, low leakage, and reliable operation within the required voltage and pressure ranges, fully satisfying the conditions for integration into the RAID-M100 and RAID-XP devices. The proposed solution contributes to domestic component localization and enhances the technical readiness of specialized detection equipment.
