Detection of magnetic suspension concentration--determination of pear-shaped tube

Detection of magnetic suspension concentration--determination of pear-shaped tubeHow to use:

In order to carry out the correct magnetic particle inspection, the concentration of the magnetic suspension liquid should be tested periodically.

1. The magnetic particle flaw detection machine The motor runs for several minutes, carries on the full agitation, causes the magnetic suspension liquid the concentration to be even.

2. The magnetic suspension from the rubber tube and nozzle out for several minutes, so that the rubber tube and nozzle in the concentration of magnetic powder into a uniform concentration.

3. The magnetic suspension 100cc into the magnetic suspension of the tube, static for 30 minutes, or to make her completely precipitate.

4. After the magnetic powder is completely precipitated, the magnetic powder deposition at the bottom of the measuring tube is read out, and the magnetic suspension is checked for the specified concentration. Fluorescent Magnetic Powder: 10 to 2.4CC, fluorescent magnetic powder: 0.1 to 0.5CC (attention should be paid to the magnetic suspension of dust and foreign bodies)

5. Less than the above concentration indicators, you need to supplement the magnetic powder, after a certain period of time, a type a standard test piece developed by a machine department is tested to obtain sufficient defect display marks and pass the test by the Inspector. Confirm that the magnetic suspension is not suitable, the use of the magnetic suspension should be fully discharged after washing and updating the magnetic suspension.

6. If the new magnetic suspension is prepared, it can be prepared according to the proportion of the 3.4 point.
