The regular maintenance of the heat sealing machine is generally completed by the instrument manager and the engineering and technical personnel. It is an organized and planned maintenance measure that is continuously cycled. This helps to grasp the operating rules of the instrument and is helpful for finding after the fault: regular The content and time of maintenance, different instruments have different practices. Generally can be divided into 3 levels:
(1) One insurance: Generally it can be carried out once a month to one quarter. The main content can be removed from the daily maintenance work of the factory, and the dust can be removed, dirt, foreign matter, tightening screws and lubricants can be removed. Check the service device, components for wear, deformation, ablation, breakdown, looseness, moisture, aging, poor grounding, etc.; detect the power supply voltage and ripple of each group, check the operation and contact of high-voltage components;
(2) Second insurance: Generally, it can be carried out once every six months to one year. In addition to a good protection, the main content can be tested and corrected for the sensitivity and accuracy of each instrument and operation control system on the console of the machine. Replace the loss of the high-voltage generator insulation, etc., in the circuit. The voltage of each test point, the waveform is systematically tested and the deflection test is performed;
(3) Three guarantees: Generally, it can be carried out once every 2-4 years: In addition to the second guarantee, the main contents can be completely disassembled for cleaning and overhaul. The components exceeding the use period should be replaced or repaired as much as possible. It is entirely possible that the instrument will be fully and thoroughly debugged to restore its working accuracy and performance to the extent that it meets or exceeds the new machine.
