FLUID METERING SYSTEM; MAIN PUMP AND AUXILIARY PUMP FOR DIFFERENT FLUIDS, CONNECTED BY MEANS FOR ADJUSTING RATIO OF FLUIDS PUMPED |
摘要 |
A precision metering, multiple fluid pumping system comprised of a main pump for pumping a primary fluid and an auxiliary pump for pumping a secondary fluid adjustably linked to work in unison with the main pump. The auxiliary pump is linked to the main pump through a rack and pinion gear system connected to an oscillating arm that operates the auxiliary pump simultaneously with the main pump. The auxiliary pump is infinitely adjustable over a selected range by varying the connecting point of the auxiliary pump to the oscillating arm. The connecting point is varied by a worm screw adjustment that provides precision adjustment and metering of a secondary fluid. The system also includes a clutch mechanism between the auxiliary pump oscillating arm and a rack and pinion gear system to disengage the auxiliary pump for priming. An additional feature is the inclusion of a leak detection system in the form of a drain conduit connected to a clear container that visibly indicates when seals in the auxiliary pump may be leaking. When fluid leaks past a main seal in the auxiliary pump, it is collected in the clear container visibly indicating the seals need replacement. |
