Qiaopu electrical operation using the standard general-purpose magnetic particle detector

One. Scope: for Qiaopu appliances can be magnetized surface crack inspection.
II. Specifications:
1, the maximum instantaneous input power: 19KVA
2, using the power supply: 380V/50Hz
3, loading conditions: 2 × 3M. 95mm2 cable.
4, the magnetization time: 0.5 to 2 seconds.
III. Instructions:
Preparation prior to use:
1, the magnetic fluid configuration: magnetic fluid concentration is appropriate, usually in the suspension medium added per liter to 30 grams of powder 12, the suspension medium is a mixture of transformer oil and kerosene, the ratio of 1:4.
Check that the power to meet the requirements, instrumentation is intact, and the current adjustment knob counter-clockwise rotation to the minimum position. 2, the magnetization of the workpiece (AC):
The two cable plug to the bottom and middle of the instrument jack, and tighten. Turn the power on, power indicator light. Set the time and magnetizing current through the magnetic, both ends of the pole and the workpiece touch probe must be firmly affixed force, pressing on the handle through the magnetic switch that started the workpiece through the magnetic magnetization. Through magnetic, the observation of KV form instructions, adjust the knob to the desired transfer current value of the workpiece through the magnetic magnetization, the magnetic fluid with a watering can will be sprayed on the surface, pay attention to spray evenly. If there are cracks in the surface, this time to the fore, such as the display is not clear, could get under fluorescent lights to enhance the observed effect. Observation is completed, the workpiece should demagnetization process, the pole at both ends of the probe in contact with the workpiece firmly affixed, press the switch on the handle of the demagnetization, the demagnetization process of the workpiece, with the demagnetization current size of the magnetic current through the same size.
IV. Caution:
1, the instrument should be Qiaopu electrical hand operation and maintenance.
2, the testing did not prepare well, do not just press the call button on magnetic and demagnetization
