METHOD FOR SYNCHRONIZING LINEAR PUMP SYSTEM

摘要

A method for synchronizing pistons within linear pumps of a variable dispense ratio system comprises operating first and second pistons, controlling the first and second pistons, and reversing direction of one of the first and second pistons. The first and second pistons are operated within first and second cylinders so that the first piston moves at a slower speed than the second piston to produce a variable dispense ratio. The first and second pistons are controlled to reverse directions whenever one piston reaches an end of its respective cylinder to produce pumping. One of the first and second pistons reverses direction before either piston reaches an end of its respective cylinder to adjust the synchronicity of the pistons.
