HCDX1500 Movable Magnetic Particle Flaw Detector AC/DC

HCDX1500 Movable Magnetic Particle Flaw Detector AC/DC

I Technical specification

II Structure characteristic

A 10 square three-core cable is equipped for the power input, one end is connected to the upper end of the circuit breaker, and the other end is connected to the air switch on the power grid distribution board, also the body is grounded.
RD and BK wires of the three-core cable are connected to the power phase conductor, and the BU wire is connected to the protective grounding cable.
Built-in fuse protection device. Turn on the external 220V power supply, turn on the device power switch, and power on the main circuit.
For easy removal and replacement of the output cable, a quick connector is used for easy connection of the magnetization coil or support probe.
The probe head of the support rod is a detachable copper head, which can contact the workpiece through the copper mesh pad, so that it is not prone to failure caused by poor contact. A rod probe with a push-button switch has a three-core cable connected to a round socket in the middle of the panel through a round aviation plug. The push-button switch on the support rod probe can be used as the green button on the operation panel. The round aviation plug on the three-core cable is connected to the round socket in the middle of the copper bar, and the foot switch can be connected with the green button on the operation panel.

V Application & usage

1. Notice and attention before use

Pls read this instruction manual in detail. First time or long time before use, pls check whether the external parts are well intact, also you can open the cover to check whether if any loose of the internal parts, but pls do not disassemble and assemble any parts without permission.

It should be stored and used in a dry, clean, well-ventilated environment without acid or alkali and other corrosive gases. This environment should not have high temperature and strong vibration or impact.

Before switching on the power supply, pls check whether the power supply is consistent with the required power supply, as well as whether the connection is correct, and whether the power grid and switch capacity meet the requirements.

2. Use & Operation

(1) Connect the power cable to the power grid, connect the power distribution cabinet, and connect the main circuit to the power grid

(2) Switch on the "Power", "Power" indicator light, then it realizes circuit control on the power supply and exhaust fan starts work;

(3) When AC magnetization is required, turn the "AC/DC" selector switch to the "AC" position, and turn the Current regulating knob "Current ADJ" to the minimum or appropriate position;

(4) Connect the copper connector of one end of two 120mm² cables to the corresponding output interface of the machine, and pay attention to the cable to connect to the corresponding output end (AC end or DC end);

(5) Press on the panel trigger button or foot switch, trigger circuit will trigger pulse to control the SCR work, and realize AC magnetization inspection;

(6) Connect the rod electrode to the workpiece, or wind the cable to the workpiece or through threading-bar technique.

(7) Press the trigger button or foot switch, adjust the current adjusting knob to make ammeter indicated the current value required by flaw detection, and then press the trigger button to complete the magnetization. Under maximum current, apply external magnetic particle inspection, generally the magnetization time is less than 2 seconds, and there should be more than 5-10 times of intermittent time (less magnetization times, multiple of intermittent time can be reduced accordingly).

(8) If demagnetization is needed, just turn the "Mag. / Demag." selector switch to the "Demag." and make operations as above steps (1) to (7);

(9) If you need to use half wave DC magnetization, just turn the "AC/DC" selection switch to the "DC" position, at this time, the internal working relay KC1 suction, complete the work switching. (It should be noted that the output cable should also use the corresponding output end after switching)

(10) When stopping use, turn off the main "Power" switch and power distribution board switch, and remove the external accessories if necessary.
