Mitech XXQ-3005 Portable X-Ray Flaw Detector

Mitech XXQ-3005 Portable X-Ray Flaw Detector

Product Overview

The Mitech XXQ-3005 is a portable inflatable X-ray generator designed for non-destructive testing (NDT). It utilizes the varying absorption levels of different materials and thicknesses to detect internal flaws in components and welded structures. The system produces high-resolution radiographic images on specialized film, revealing the size, shape, and location of internal defects with clarity and precision.

Engineered for versatility and portability, the XXQ-3005 features a compact design, light weight, and intuitive operation. It is especially suitable for field inspections, including high-altitude and remote applications. The system requires no special surface preparation and is largely unaffected by material grain size, making it ideal for a wide range of industrial inspection needs.

Applications

The XXQ-3005 is widely used across industries such as:

• Shipbuilding

• Aerospace and aviation

• Railway inspection

• Machinery and heavy equipment manufacturing

• Pressure vessels and boilers

• Oil and gas

• Chemical processing

• National defense and military applications

Working Principle

The detector operates by generating high-voltage X-rays via a silicon-controlled rectifier circuit. Electrons are accelerated in the X-ray tube and collide with the anode, generating X-rays. These rays penetrate the test material, with their intensity reduced based on the internal structure.

The variations in X-ray intensity are captured on special film coated with silver halide emulsion. Areas receiving higher exposure turn darker during processing. This contrast allows accurate visualization and assessment of internal flaws, enabling inspectors to determine the type, size, and position of defects.

Environmental and Operating Conditions

• Ambient Temperature: -25°C to 40°C

• Relative Humidity: ≤ 85%

• Safe Operating Pressure: 0.35 – 0.50 MPa

• Note: Do not operate the device if air pressure is below 0.35 MPa.

Key Features

• Microcomputer control for precise operation

• Compact and lightweight construction for easy transport and on-site use

• Built-in over-temperature protection that automatically cuts off high voltage to protect the X-ray tube

• Stable mA unit adjusts filament voltage and frequency to ensure consistent X-ray output

• Continuously adjustable kV for compatibility with various material types

• Anti-interference circuit reduces electrical noise from high-voltage impulses

• Comprehensive protection features and fault code display for diagnostics

• Duty cycle of 1:1 for balanced operation and cooling

• Delayed high-voltage start to allow the operator to exit the hazard zone

• Electrical isolation between the high-voltage section and control system enhances operational safety

• Compatible with unstable power sources such as generator units

Operation Instructions

1. Connect the system and power on. Ensure the fan and display are functioning.

2. Allow 15 seconds for the system to enter standby mode.

3. Preheat the tube to ensure vacuum stability.

4. Set the desired tube voltage (kV) and exposure time.

5. Press the high-voltage (HV) button to start exposure. The system will automatically stop after the preset duration.

6. Use the delayed start function (0.1 to 5 minutes) to exit the radiation area safely before activation.

7. Cancel the delay by restarting the unit or pressing the HV button again.
