Summary of empirical data: Choose a vacuum suction cup with a diameter of 50 to work under -0.04MPa pressure or choose a vacuum suction cup with a diameter of 4,40 to work under -0.087MPa pressure, in order to carry out transportation, through the above data analysis, I want to tell you that it is necessary to use the vacuum suction cup reasonably, in order to play its due role, for this reason as a vacuum suction cup manufacturer we, All kinds of vacuum suction cups (vacuum suction principle detail paper) are sorted out for everyone, and the data analysis is carried out.

1. Press the operating button of the grinding wheel motor to start the switch of the electric permanent magnet chuck. Note: the workpiece cannot be drawn, the contact of the relay is interlocked, and the grinding wheel motor cannot be started. 2, open the special distribution box of the machine tool, use the measuring pen to detect whether there is electricity at both ends of the fuse, and then use the multimeter 500V to measure the power supply voltage to 380V.
