In the use of powder coating equipment, we should pay attention to the oil injection and exhaust operation of the powder coating equipment system, according to the relevant operating regulations. Enter the whole system, supply the powder coating equipment system after the oil is full, then open the cold oil replacement valve for exhaust operation, and close the replacement valve after exhausting. When the oil is filled up, it enters the expansion tank, and the oil level of the powder coating equipment rises beyond the overflow port and returns to the oil filling tank, which will close the oil injection pump of the powder coating equipment and the inlet and outlet oil valves of the powder coating equipment.
After the cold cycle exhaust is completed, the dehydration and exhaust procedure must be carried out in the form of gradual temperature rise, so that the residual air, moisture, and low-boiling vapors in the powder coating equipment system can be further exhausted, and the temperature rises by 20 degrees per hour. The heating rate is carried out for about five to six hours. If there is no abnormal situation, let the powder coating equipment heat up to the temperature to be used, so that it can be put into normal work.
In order to ensure the safe use of powder coating equipment, during the operation of its heat transfer oil product, the oil position of the expansion tank of the powder coating equipment is as low as the position of the alarm oil, and the position of the oil should be raised as much as possible. timely replenishment.
