Full set of mechanical parts;
Electrical control part.
5 Test method
5.1 The polarity of the magnetic pole in Article 4.5 shall be checked by permanent magnet block or tolsado meter. 5.2 The withstand voltage test in Article 4.6 shall be carried out in accordance with Article 6.3 of GB998. 5.3 The requirements of Articles 4.10 and 4.11 shall be checked and measured in an idling test of not less than 4h. The machine noise shall be measured with a sound level meter at a distance of 1m from the machine and 1.5m above the ground. 5.4 The measurement of the temperature rise of the exciting coil in the table of Article 3.1 shall be carried out in accordance with Article 5.3.1 of GB998 when the current is 2A. 5.5 The magnetic induction intensity shall be measured by the following method using a Tesla meter with an accuracy level not less than 2.5 and a probe with a thickness not greater than 2mm:
For the measurement of the magnetic induction intensity of the permanent magnet feeder in the table of 3.1, the average value of 13a.
points shall be taken at 4mm from the magnetic pole surface on the middle section of the magnetic system, as shown in Figure 2;
b, for the magnetic induction intensity in the table of 3.1, it shall be measured at the tip of the magnetic disk when the current is 2A and the working gap is 3mm. When measuring, the arc length of the magnetic disk along the width of the feeder disk on the middle magnetic pole side shall be evenly divided into 10 points (see Figure 3), and the average value shall be taken. 5.6 For the painted appearance quality disk in 4.12, the paint film thickness shall be measured with a magnetic thickness gauge, and the paint film adhesion shall be tested in accordance with the provisions of GB1720.
