1. When the heat sealing plastic film is not strong, it can be reflected:
a, whether the vibration coil can be loose;
b, whether the input voltage can be too low;
c. Whether the cross-connect capacitor can be broken;
d. The vibration tube is aged or lost.
2, Gongfu controllers can be introspected when it is forbidden or lost control:
a. Whether the breaker cable package in the man-hour controller can be broken;
b. Whether the dielectric container and other containers connected at both ends of the relay can be damaged;
c. Can the potentiometer and carbon film resistor be damaged?
3, every day with a cotton yarn with gasoline to clear the copper knife.
4. Self-denying tools are made of bronze.
5. Add smooth oil to each sliding place every ten days.
6. When the temperature is high, the side door can be turned over, and the vibration tube and the electron tube are blown by the electric fan, but special attention should be paid to the safety, and the wooden fence should be used when necessary.
7. When the power input is determined, and the voltmeter has no index, and the tube is not lit, the following components can be reflected:
a, the power switch is in poor contact;
b, the low pressure conditioning switch is damaged;
c. Can each joint have a virtual soldering sight?
8. When the index of the screen flow meter is significantly lower than usual, it can be reflected whether the rectification can be normal, whether the vibration tube can be aging or damaged.
9. When the brightness and voltage index of the tube inside the machine are normal, the pedal switch has a "ping" sound and the screen flow meter has no index (heating without fever) can reflect the following parts:
a, wirewound resistor R1 is open;
b, the screen lead is shorted;
c. The contact of the AC contactor J1 is damaged.
10, when the screen flow chart index is infinite, and burn out the fuse fuse can reflect:
a, whether the electrode (copper knife and lower electrode plate) can be in direct contact;
b. Whether the high voltage ceramic bypass capacitor can be broken down, and other local high voltage can be grounded.
