How to do daily maintenance of tape machine
07-20
1. Precautions for daily inspection of the sealing tape machine
1. Carefully monitor and record the display parameters on the human-machine interface of the frequency converter, and report any abnormalities immediately
2. Carefully monitor and record the ambient temperature of the frequency conversion room. The ambient temperature should be within Between -5℃～40℃. The temperature rise of the phase-shifting transformer cannot exceed 130℃.
3. When the temperature is high in summer, the ventilation and heat dissipation of the inverter installation site should be strengthened. Make sure that the surrounding air does not contain excessive dust, acid, salt, corrosive and explosive gases
4. Summer is the rainy season, so rainwater should be prevented from entering the inside of the inverter (for example, rainwater enters along the wind outlet)
5. The inverter cabinet door The filter should usually be cleaned once a week; if the working environment is dusty, the cleaning interval should be shortened according to the actual situation.
6. During normal operation of the inverter, a piece of A4 paper with standard thickness should be firmly adsorbed on the air inlet of the cabinet door to filter Online
7. The frequency conversion room must be kept clean and tidy and should be cleaned at any time according to the actual situation on site.
8. The ventilation and lighting in the frequency conversion room must be good, and the ventilation and heat dissipation equipment (air conditioner, ventilation fan, etc.) can operate normally.
2. Items that need maintenance after the tape machine is shut down
1. Use a vacuum cleaner with a plastic nozzle to thoroughly clean the inside and outside of the frequency converter cabinet. Make sure there is no excess dust around the equipment.
2. Check the ventilation and lighting equipment in the frequency conversion room to ensure that the ventilation equipment can operate normally.
3. Check that the connections between the cables inside the inverter should be correct and reliable.
4. Check that all groundings in the inverter cabinet should be reliable and that the grounding points are not rusty
. 5. All cables inside the inverter should be tightened again every six months (within). Connecting nut
6. When the inverter of the sealing tape machine resumes operation after being shut down for a long time, the insulation of the inverter (including the phase-shifting transformer and the main circuit of the bypass cabinet) should be measured, and a 2500V megger should be used. Only after the insulation test is qualified can the frequency converter be started.
The above is about how to perform daily maintenance of the tape machine. I hope it can help you.
