  • Patent number: 9215958
    Abstract: A pick-up head system comprises a housing and a main fan connected in air suctioning relation to the housing for causing the interior of the housing to have a reduced internal air pressure. A secondary substantially continuously available source of low air pressure has an inlet connected in air suctioning relation to the housing. A valve is operatively mounted between the housing and the inlet of the source of low air pressure. A control mechanism is operatively connected to the valve and responsive to at least one operational condition in the pick-up head system. In a reduced-flow position, the air pressure in the housing is unaffected by the vacuum tank. In the increased-flow position, when the at least one operational condition passes a threshold, the vacuum tank decreases the air pressure in the housing, thus precluding the escape of dust and other fine particulate matter from the interior of the housing.

  • Patent number: 9010367
    Abstract: The controller of the plural component proportioner (10) dispenses both components (or all three if a three component material) as necessary to maintain the correct mix ratio. The fluid displacement measuring technique described allows this proportioning to take place with the “A” or main component pump always able to supply fluid to the spray gun without being stopped. The “B” component, at a higher pressure, is added as necessary to control ratio. The control can determine whether the pumps were properly loaded with fluid, and the fluid was properly compressed for accurate measurement. This technique allows for the proportioned fluids to be provided to the spray gun(s) at high flow rates and consistent spray pressure without interruption.

  • Patent number: 8851111
    Abstract: 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.

  • Publication number: 20100307619
    Abstract: The present invention provides a water supply apparatus capable of performing a backup operation, without lowering water supply capability, when a failure has occurred in one control substrate due to surge or noise caused by lightning or due to lifetimes of various sensors, by switching to the other control substrate, and capable of reliably performing the backup operation by means of devices that prevent failure of the control substrates. The water supply apparatus (1) includes: a plurality of pumps (3); a plurality of inverters (INV) each configured to change and control a rotational frequency of a corresponding one of the plurality of pumps (3); and a plurality of control substrates (CN) configured to control the plurality of inverters (INV). When an abnormality occurs in one control substrate, other control substrate backs up the one control substrate to thereby allow the water supply apparatus to continue its operations.

  • Publication number: 20100272581
    Abstract: Disclosed is a pumping system comprising a pump having a rigid outer casing defining an interior space and a tube structure in the interior space, the tube structure being flexible and substantially inelastic. The interior of the tube structure defines a pumping chamber for receiving pumped fluid. The tube structure is movable between laterally expanded and collapsed conditions thereby providing discharge and intake strokes. The pumping chamber receives pumped fluid to cause the tube structure to move towards the expanded condition and undergo an intake stroke. The pumping chamber—undergoes a discharge stroke upon collapsing of the tube structure. The pumping system also comprises a delivery means and a supplying means for delivering pumped fluid to the pumping chamber and for supplying actuating fluid to an actuating region around the tube structure in timed sequence to cause the tube structure to undergo discharge and intake strokes.

  • Publication number: 20080302389
    Abstract: A pumping unit is provided that allows at least four passes to be made simultaneously with a single pumping unit. A single engine is used to drive two pumps, each connected into separate pumping circuits. Fluid flow in each of the pumping circuits is controlled by respective flow control elements on the pumping circuits, as for example a variable flow valve. Two engines may thus be used to drive four pumps.

  • Patent number: 7270145
    Abstract: The invention relates to valves for air compressors, and more particularly, to an unloading/venting valve having integrated therewith a high-pressure protection valve where a pressure reducing valve has a discharge port in communication with the air system and a vent. The valve utilizes a valve body biased to form a seal between the discharge port and the vent. A governor monitors the air pressure in the system and generates a signal to move the valve body against the bias and unloads the system when a first predetermined threshold pressure is reached. In the event of a failure of the valve body to move at the first threshold pressure, the valve body is movable against the bias in response to a second predetermined threshold pressure reached in the system, thereby unloading the system.
