Desk Training Purpose 200mm Stroke Magnetic Particle Flaw Detector

Training Purpose Magnetic Particle Flaw Detector Magnetic Particle Testing Machine

Standard magnetic particle flaw detector is applicable to detect the surface and near surface defects such as cracks and slag of small or medium-sized ferromagnetic class workpiece (such as bolt, pin shaft, shaft sleeve, gear, gear ring, crankshaft, etc.). Generally, these defects are caused by forging, quenching, grinding, and fatigue.

Model HMP-500NX is specially designed for school and colleague training purpost.

1.6 The system has strong stirring, the V-shaped structure ensures that the magnetic powder is not easy to precipitate, and the spray pressure is adjustable;The capacity is 20L;

1.7. Magnetization and demagnetization power supply system:

The equipment adopts AC magnetization method, which is two sets of independent magnetization power supplies. The two main transformers provide the magnetizing current respectively. The controllable module converter technology is used to control the current of the circuit, and the isolated voltage is sent to the electrodes and coils. The size is continuously adjustable and the corresponding instrument indication is set. The current can be preset, and the alarm will be alarmed when the preset current is insufficient or exceeded to prevent misdetection and missed detection, and ensure that the workpiece obtains the specified magnetization intensity. AC with power-off phase control function to maintain stable residual magnetism, which can be used for residual magnetism flaw detection.

With AC attenuation method demagnetization function.

The material of the current path: all red copper bars or copper cables.

1.8. Electrical control system:

1) The electrical control system is controlled by OMRON PLC, including controllable modules and their protection devices, current adjustment trigger devices, ammeters, control buttons and indicator lights, cylinders, triples, solenoid valves, pressure regulating valves, air switches, intermediate relays, Control devices such as AC contactors. Main power circuit breaker with overload protection.

2) Man-machine interface control system:

The computer (human-machine interface system) controls the magnetization current, magnetization time, magnetization, etc., which greatly improves the detection accuracy, and can automatically complete the step-by-step operation of magnetization, magnetization current preselection, and tracking.

The touch screen programmable display communicates with the PLC programmable controller through an adapter to directly display the key parameters of the system. And set the authority password, and the parameters can be adjusted within the authority. Screen design: Homepage-company name. Any touch can enter the main screen-"Main Menu", "Work Page", "Alarm Record", "Precautions", "Current Waveform", touch each function key to automatically switch to the corresponding screen, and the process parameters of various typical workpieces Can be stored.

The magnetizing current can be preset, and the automatic tracking circuit is formed through the touch screen programmable display system, and the error between the preselected value and the actual passing current value is ≤±3%.

The system has fault self-diagnosis function. Over-current, under-current, abnormal air pressure, excessive temperature rise of the main circuit, sound and light alarms and automatically stop working.

3) The equipment shell is grounded reliably, and the insulation resistance of the whole machine is ≥2MΩ.

4) The equipment has complete safety protection and interlocking and alarm functions.

5) The electrical schematic diagram, wiring diagram and the actual circuit of the equipment should be completely consistent.

6) The PLC contact is equipped with an intermediate relay to protect the contact.

7) The wiring of each electrical component is required to be marked with a wire number, and the wiring between each component is provided with a wire slot board.
