SPRAY SYSTEM PRESSURE AND RATIO CONTROL |
摘要 |
A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a target primary-to-secondary spray component flow ratio, sensing an output pressure of the first pump, controlling the first pump to a first speed set via a proportional-integral-derivative loop using the sensed output pressure and the target spray pressure, and controlling the second pump to a second speed equal to the first speed multiplied by the target primary-to-secondary spray component flow ratio. |
