Maintenance

Model PZ-5QSpraying Machine is designed for harsh site condition, requiring little maintenance. However, like other rotating type spraying machine, it also needs routine maintenance.

1.The sealing plate and the rotator lining plate are key parts of this machine, so it is essential to pay much attention to their maintenance to avoid failure in operation.

Pressure on the sealing plate exerted by the fastening system is not even, the max. pressure find itself between the mix outlet and the exhaust air outlet. And this max. pressure point is drifting due to rotation of the rotator, however this pressure difference can be regulated by the fastening system itself. So the air leakage from the jointing surface during machine running is little.

Proper fastening is essential to reduce wear and waste cost. If the fastening is not proper, the compressed air along with the fine grain of mixture will leak between two plates. This type of fine grain can corrade the sealing plate and make it useless.

Excessive fastening will lead to excessive abrasion and overheating of the sealing plate. 110℃ is the max. temperature sustainable to the sealing plate. The normal working temperature of it is less than 80℃.
