Natural gas medium and high temperature drying tunnel operation process and usage instructions

1. Before starting the machine, check or adjust the set temperature of each heating zone to meet the process temperature of the coating. Generally, the set temperature of the inner coating is between 150-280 °C and the second section is 380-430 °C (if The coating should be slightly adjusted.) Generally, the set temperature of the outer coating is between 120-200 °C, and the second section is 260-300 °C (if the coating is different, it should be slightly adjusted). After setting the process temperature of each group, Press its switch to the measurement position.

2. Check if the tachometer is at zero position. If it is not at the zero position, turn it to the left position. Then turn on the net belt motor and rotate the tachometer to adjust the speed of the net belt to the line speed required by the process.

3. Before starting the dry furnace or sintering furnace, first check whether the natural gas pressure gauge is in the normal range (10G dynamic pressure is 3-5kpa, 34G dynamic pressure is 4-6kpa)

4. Start the stirring fan and start the burner (you must start the stirring fan first and then start the burner!!!).

5. Observe the temperature gauge. If the process temperature is reached, you can start to put the workpiece into production.

6. Each piece of product should be inspected for quality to meet the standard requirements.

Precautions

1. The operator must carry out training. The personnel without the training or the consent of the workshop shall not adjust the electrical switch, process temperature, damper and mesh belt running speed without authorization.

2. Before starting the machine, check whether the motors are running normally. If there is abnormal sound, stop the machine immediately.

3. During the operation, if the network belt is found to be biased or slack, it should be adjusted in time.

4. After each shift is warmed up, if the temperature is abnormal, check whether the burner or thermocouple is abnormal.

5. At the end of the work, other power sources should be turned off, but the circulating fan should also be turned off automatically after 1.5 hours of operation to avoid overheating of the burner on the combustion chamber due to immediate shutdown! !

Paint operation process and method

1. Generally, single-layer wow paint, just after opening the package, stir it evenly with a wooden stick, put a proper amount of thinner, filter it through a 200-250 mesh filter, and then put it into a pressure tank or a pressure pump to carry out the spraying operation; If the paint is different, it should be adjusted).

2. The spray gunner should adjust the angle of the spray gun and the amount of oil discharged from the distance to avoid unnecessary waste.

3, the workpiece is sprayed into the drying oven, should check whether the product meets the product quality standards, the above should be a little feel (the residual heat can not be too high), in order to carry out the surface coating operation; (with or without sag, thin, etc.) Put it into the drying oven; check the color after drying, if there is any abnormality, compared with the swatch, no abnormality can be produced normally.

Fourth, maintenance and maintenance

1. Regularly refuel the rotating bearings and add a butter to the rotating chain every week.

2. The gearbox is added with butter every three months and the butter is replaced once a year.

3. Each motor, fan, water pump and electrical components should be inspected regularly. If abnormal sound is found during work, it must be stopped immediately.
