    摘要： A mechanical proportioner is provided with two pump lowers which are connected together by a yolk underneath an air-operated reciprocating piston pump. The pumps are staggered axially so as to enable overlapping of certain portions thereof thereby enabling the center-to-center distance to be minimized. The mix manifold is constructed in a concentric fashion such that mixed material does not come into contact with the mix manifold until it enters the static mixer at the exit of the manifold which is an easily disposable and replaceable part. The purge solvent valves on the mix manifold are each provided with an extension of their respective handles. If either purge valve is in its open position, a separate interlock handle operating the A and B side valves at the manifold inlet is prevented from opening. Similarly, if the interlock handle operating the A and B side valves is open, the purge valves cannot be opened.

    摘要： An electronic apparatus is provided for dispensing plural component materials having first and second (and optionally third) components and a desired ratio between the components. The apparatus has first and second reciprocating pumps (4), each of the pumps (4) being connected to a source of one of said components, first and second reciprocating drivers (5), each driver (5) being connected to drive one of the pumps and forming a driver-pump set, a position sensor (6) attached to each driver-pump set, each position sensor (6) outputting increments of resolution corresponding to a fixed volume being pumped by the driver-pump set to which it is connected, and a controller attached to the drivers and the position sensors to alternately move one of the driver-pump sets one said increment and the other of the driver-pump sets the product of one increment and the ratio.

    摘要： The controller of the plural component proportioner (10) dispenses both components (or all three if a three component material) simultaneously (at least initially) and maintains ratio at the end of each predetermined volume of material by determining which component pump (12) has reached the desired amount of travel (given the resolution available) and using a valve (16) to shut off output of that pump until the other side has caught up. At pump changeover, the output valve for that pump (12) is shut off and the air motor (12a) allowed to run until travel stops to account for cavitation, air entrainment, compressibility, or poor inlet check performance.
