6 Inspection methods and inspection rules
6.1 Factory inspection
Eddy current cars should be inspected one by one by the quality inspection department of the manufacturer, and can only be shipped after passing the inspection. 6.1.1 The insulation level of the excitation coil should be inspected in accordance with the provisions of 5.4. 6.1.2 Use a 500V megohmmeter to check the resistance of the excitation coil to ground in accordance with the provisions of 5.5. 6.1.3 Turn the rotor shaft and press 5.2. Check the air gap value according to the provisions of 2. Every time it rotates 120, use a feeler gauge to measure the gap value through the six observation holes on both sides of the eddy current brake. Rotate three times continuously, and measure three gap values ​​for each observation hole according to the above provisions. Among the 18 air gaps, more than 14 should meet the requirements to be qualified: the air gap value is equal to the gap value plus the coating thickness of the stator outer cylindrical surface plus the coating thickness of the rotor inner cylindrical surface). 6.1.4 Check the operation according to the provisions of 5.8, at a speed of not less than 150r/min, without cooling water (wind), without inputting excitation current, and run idly for more than 20min.
At a speed of not less than 250r/min, pass cooling water (wind), do not input excitation current, and run idly for more than 1h. The amount of cooling water for water-cooled type is based on a small amount of water spraying out after the screw plugs are opened at the upper observation holes on both sides of the eddy current brake. Check the temperature rise of the bearing and the seals at all locations according to the provisions of 5.9 and 5.10. 1) The coating thickness shall be based on the production inspection record or on-site disassembly inspection. 4
6.1.5 Inspect the weld quality according to the provisions of 5.6. 6.1.6 Inspect the coating quality according to the provisions of 5.7. 6.1.7 Inspect the electrical equipment of eddy current brake according to the provisions of 5.3. 6.2 Type inspection
6.2.1 Type inspection shall be carried out in any of the following situations: a) When the new product or old product is transferred to the factory for trial production and identification; b) After formal production, if there are major changes in structure, materials, and processes, which may affect product performance; c) When the quality and technical supervision agency proposes a requirement for type inspection. 6.2.2 Type inspection shall be carried out after all factory inspection items are qualified. SY/T 55332002
6.2.3 According to the maximum no-load speed specified in Table 1, water (wind) no-load operation shall be carried out, and the time shall be no less than J: 20min. In the bearing temperature rise, it shall comply with the provisions of 5.9.

At the rated speed, the braking torque generated by the maximum excitation power should comply with the provisions in Table 1.
6.2.5 After the load test, the excitation current is cut off and the brake braking effect is terminated. At the rated speed, the reverse rotation brake is turned.
