Inspect plastic processing equipment regularly to prevent potential safety risks

After the operation of plastic processing equipment for a period of time, even if everything runs normally, it is necessary to check and maintain the processing equipment regularly. Because regular inspection and maintenance can preinspect the hidden security risks of processing equipment, and can be dealt with in time. In this way, it can avoid the sudden failure of plastic processing equipment because it is not found in time, which will affect the progress of work and cause losses. By then, it will be late to check and maintain.

Inspection steps for plastic processing equipment:

1. Check the plastic processing equipment on each part of the oil and dust in the electric control box is accumulated, and timely cleaning, erasure treatment.
2. Open the reducer box and bearing gland of plastic processing equipment, check the quality of lubricating oil and the amount of metal powder in the oil. If the lubricating oil inside becomes dirty, it is necessary to clean and change the oil.
3. Check the wear of various transmission parts of plastic processing equipment. The gears with serious wear should be mapped, so that they can be replaced during the next maintenance.
4. Check the wear of plastic processing equipment v-belt drive belt, and adjust the tightness of the v-belt installation, v-belt wear serious to be replaced.
5. Check the wear of plastic processing equipment barrel and screw, for slight scratches and wear rough surface, use whetstone or fine emery cloth to smooth and smooth, record the measured size of the barrel and screw working face.

6. Record the type and specification of v-belt and bearing with severe wear, and put forward the order plan for damaged parts after maintenance, so as to prepare for replacement in the next maintenance.

7. Check and correct the difference between the heating temperature of plastic processing equipment barrel (measured with mercury thermometer) and the temperature displayed on the instrument to ensure the correct operation of extrusion process temperature.

8. Adjust and test each safety alarm device to verify its reliability and accuracy.

9. Test and check whether all kinds of pipelines (water, gas and lubricating oil) are unobpatened, and repair the leaking and blocking parts.

10. Check and adjust the position of electric heating device, cooling fan and safety cover of zhejiang plastic processing equipment to ensure that they can work effectively and normally.
