The annual inspection of the feeding port refers to the inspection and maintenance of the raw material feeding port in the production process every year to ensure the smooth progress of the production process. The annual inspection of the feeding port is a very important work link, which can effectively prevent accidents and ensure the normal operation of production. The specific steps and precautions for the annual inspection of the feeding port are as follows:

First, the equipment needs to be thoroughly cleaned before the annual inspection of the feeding port to ensure that there is no dust, debris and other impurities on the surface of the feeding port. Then, check the sealing performance of the feeding port to ensure that the sealing ring of the feeding port is intact and has no damage or aging. For transmission parts, it is necessary to check whether the transmission belt, chain, gear, etc. are in good condition to ensure the normal operation of the transmission system.

Secondly, check the auxiliary equipment and instruments, such as checking whether the control valve, valve transmission system, valve seal, etc. of the feeding port are normal to ensure the normal use of the equipment. At the same time, calibrate the instruments and sensors to ensure the accuracy and sensitivity of the instruments.

Then, perform performance tests on the feeding port, such as testing the switch flexibility, delivery speed and other parameters of the feeding port to ensure the normal operation of the equipment. For the automation system, it is necessary to test whether the automatic control system is normal to ensure the reliability of the automation process.

Finally, a comprehensive assessment is made on the working status of the entire feeding port, and problems are solved in a timely manner, and they are recorded and reported. It should be noted that when conducting the annual inspection of the feeding port, attention should be paid to safety protection measures and relevant operating procedures should be followed to ensure the safety and smooth progress of the operation.

In short, the annual inspection of the feeding port is an important work link, which plays a vital role in the normal operation of the production process. Through the annual inspection of the feeding port, problems can be found in time, accidents can be prevented, production efficiency can be improved, and production safety can be guaranteed. Therefore, when conducting the annual inspection of the feeding port, it is necessary to be serious and responsible, meticulous, and ensure that the work is comprehensive, meticulous and accurate.
