| 122 | Additive Proportioning System | US13589095 | 2012-08-18 | US20130048099A1 | 2013-02-28 | Dennis W. Crabtree |
| The subject invention described herein is directed to an improved fluid powered system for dispensing a selectively variable proportion of additives into a primary fluid supply line such as is commonly encountered in the firefight industry where it is desirable to proportion foam concentrates into a water line. The subject invention features a water driven motor that is integral to a variable displacement additive pump. A proportioning adjustment allows the solution % to be adjusted. Once set, the additive percent varies in direct proportion to the water flow rate in order to maintain a nearly constant solution percentage over a broad flow range. | ||||||

| 134 | Metering pump with self-calibration and health prediction | US11359191 | 2006-02-22 | US20070196213A1 | 2007-08-23 | Douglas Parsons; Kevin Alstrin |
| A metering pump incorporates a method of relating inner loop current to a pump output pressure. Pump/motor speed, which correlates to current, is measured and controlled by a system controller. System temperature is also measured by the system controller. The controller monitors the measured system temperature and provides for compensation for system losses, including inductive-resistive (IR) losses, and for density and viscosity shifts, within a pre-determined allowable system temperature operating range. An initial system calibration is conducted using a “shut-off” test, where the metering pump is run at a very slow known speed while the system is shut-off. After initial start-up, a health-monitoring feature continues to monitor the current as an indicator of pump performance and continuously adjusts a motor speed to maintain a desired level of pump performance. This provides the system with the ability to compensate for performance losses, including performance losses due to variations in operating conditions, and to compensate for pump wear. | ||||||
| 135 | Metering pump for liquid products | US10258632 | 2000-05-08 | US06857860B1 | 2005-02-22 | Philippe Zimmermann; Joseph Ruegg |
| The invention concerns a metering gear pump comprising a set of gears supported and guided solely by the inner peripheral surface of the lobe of the chamber wherein they are housed. They do not comprise any shaft to act as support or guide, thereby enabling to reduce significantly useless spaced difficult to rinse when changing the product to be pumped. For the same purpose, the driving shaft is flexibly connected to the driving gear. Such arrangement provides the advantage of requiring only one single packing seal. Such a pump, connected to a drive motor and an encoder delivering a signal proportional to the number of pump cycles, enables to provide an accurate metering pump for numerous uses. | ||||||

| A liquid injection arrangement for inserting a foaming agent into water for a fire fighting application, or a similar use, requires that metered quantities of a liquid chemical foamant or other agent be injected into a conduit assembly conveying a water stream. A desired concentration of foamant requires varying the foamant flow as a function of water flow. A tank holds a quantity of liquid chemical foamant, and at least one pump has an inlet port coupled to the tank and an outlet port coupled to the conduit assembly. A hydraulic motor drives the pump and a valve is coupled with the hydraulic motor and a source of pressurized hydraulic fluid. A sensor is placed adjacent to the outlet port of the pump to feed back a signal representing the pressure of the water flowing through the conduit assembly, and a control system is responsive to the signal and to a flow rate of water flowing through the conduit assembly, producing a signal for controlling a speed at which the hydraulic motor drives the foamant pump. A feed-back loop is provided that monitors the flow rate and pressure of the water in order to control the foamant flow. The foamant outlet and the water/foam outlet pressure sensor are placed at substantially the same position in the flow so that the foam addition can be controlled to produce an accurately metered quantity of the liquid foamant in the water stream exiting the conduit assembly and to maintain the desired concentration. | ||||||
