摘要:
A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a material-specific pressure factor margin, sensing an output pressure of the second pump, and identifying a failure condition in the event that the sensed output pressure remains further than the pressure factor margin from the target spray pressure for at least a threshold time.

A removable cartridge for use with a liquid diffusion device is provided. The removable cartridge includes a cartridge housing defining an internal housing cavity, partially filled with a liquid to be diffused, and a diffusion head positioned within the internal housing cavity with a venturi device for generating diffused liquid from the liquid contained in the internal housing cavity. The diffusion head defines at least a portion of a gas supply conduit that extends from a bottom end of the removable cartridge to the venturi device through the liquid to be diffused to enable the venturi device to be supplied with pressurized gas from an external source via the bottom end of the removable cartridge.

The invention provides a machine (21) for mixing and applying continuously a bicomponent sealing material formed by mixing a base and a hardener in a preestablished ratio that is used, for example, in joining areas of structural elements of aircraft structures. Their metering chambers (25, 25') are configured with a volumetric ratio between them adapted to the volumetric ratio of mixture of the base and the hardener and the pushing device (31) comprises means for actuating the pistons (33, 33') allowing different displacement speeds and control means so that the outflow of said metering chambers (25, 25') is that required for the base and hardener can reach the mixing head (43) in a pre-established weight ratio.

A liquid container system for a spray gun may include a cup including an open top, the top including a cup lip, the cup lip including a cup lip recess; a ring, the ring including a bottom wall and a peripheral flange extending upward from a periphery of the bottom wall, the peripheral flange configured to be inserted into the cup lip recess; a liner including a liner lip at an open end, the liner insertable through the ring into the cup, the bottom side of the liner lip adapted to rest on the ring bottom wall when the liner is inserted into the cup; and a lid configured to close the open end of the liner, the lid including a flexible gasket that depends from a flange on the periphery of the lid such that the lid, liner and ring form a liquid tight unit. Another liquid container system for use with a spray gun may comprise a cup having an open top with a cup lip recess; a ring having a bottom wall and a peripheral flange extending upward from a periphery of the bottom wall, the peripheral flange receivable within the cup lip recess; a liner having a liner lip at open end, the liner lip resting on the ring bottom wall when the liner is inserted into the cup, the liner supported within the cup by the ring; and a lid having a flexible gasket that cooperates with the liner lip to create a liquid tight seal.

A removable reservoir for a paint spray gun has an outer container (12) provided with an air vent (12A), a removable, self-supporting liner (13) adapted to fit within the container (12) and a lid (15) co-operable with the liner (13) to form a fluid reservoir (13). The lid (15) has an outlet (17) and a filter (19) that covers the outlet (17) whereby paint withdrawn from inside liner (13) when the reservoir is attached to a spray gun flows through the filter (19) and the outlet (17) to the spray gun. The liner (13) is adapted to collapse when paint is withdrawn from the liner (13) during operation of the spray gun.
摘要:
The present invention discloses a device introduced into a tip for spraying droplets, which provides for the control of the flow, distribution and formation of spray droplets, within the spectrum of droplet sizes considered as aerosols ( The present invention comprises a body (1) which has in its inner part, in the central region, a tip (11), of geometry of the venturi type, configuring an area for constriction to the passage of air flow, linked to the cylindrical casing (5) and a second low pressure chamber (12), and the geometry of the tip (11) causes the increase in the speed of the air flow and the consequent reduction in the pressure, thus causing the suction of the liquid and the formation of the droplets by the disruption of the surface tension when the air stream is passed through said tip (11).
摘要:
Spray gun comprises a spray nozzle and a removable liner (35) that fits closely into a reservoir (6). The liner collapses as fluid is dispensed from the nozzle. Preferably the spray gun is gravity fed. The fluid reservoir and liner are removable and collapsible for disposal. The liner is secured to the reservoir by a removable lid. The reservoir (container) is plastic, especially polypropylene or polyethylene. The liner is semi-rigid thermo-vacuum formed plastic.

A fluid system (1) has a fluid control device (30) that can receive a gas hose (46) and fluid hose. The fluid control device can also have a gas source (40) and can be configured to receive the liquid hose. The fluid control device is provided to output a fluid flow into an output hose (50) The fluid control device can be positioned near a liquid source or a nozzle (22) of the output hose. In another arrangement, the fluid control device can receive low pressure fluid and deliver high pressure fluid to a high pressure device. The fluid system can have a hose reel apparatus (210) for spooling a hose connected to the fluid control device and the high pressure device.
