Sprayer thermal protection

摘要

In an electric airless sprayer ( 16 ), as the motor ( 14 ) temperature approaches allowable limits, several performance cutbacks can be used to prevent overheating. The preferred method is to gradually reduce the controlled pressure. If the temperature continues to rise, the control ( 20 ) switches to on/off or deadband control. If the temperature continues to rise in spite of these measures, the control ( 20 ) shuts the unit down.
