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 method of actuating a double-action pump assembly with a reciprocating plunger includes signaling the reciprocating plunger to stop for a changeover period; while the pump is stopping, signaling the first inlet and outlet valves to close; while the first inlet and outlet valves are closing, signaling the second inlet and outlet valves to open, such that the second inlet and outlet valves begin to mechanically open at least a dwell period after the first inlet and outlet valves have entirely closed; and signaling the reciprocating plunger to begin moving while the second inlet and outlet valves are closing.

Fluid product dispenser comprising: • two reservoirs (R1, R2), • two pumps (P1, P2) and • two push buttons (B1, B2), namely a first push button (B1) for activating a first pump (P1) connected to a first reservoir (R1) containing a first fluid product (F1), and a second push button (B2) for activating a second pump (P2) connected to a second reservoir (R2) containing a second fluid product (F2), the dispenser additionally comprising • a third push button (B3) for dispensing a mixture of the first and second fluid products (F1, F2), the first fluid product (F1) being dispensed through a first dispensing orifice (O1), the second fluid product (F2) being dispensed through a second dispensing orifice (O2), and the mixture of the two fluid products (F1, F2) being dispensed through a third dispensing orifice (O3) formed by the third push button (B3).
摘要:
A powder supplying device for a powder coating installation with at least one closed or closable powder container, which has a cuboidal powder chamber for coating powder. In order to quickly change the powder, one or more cleaning compressed-air inlets to which a compressed air source can be connected in a cleaning operation of the powder coating installation for removing residual powder from the powder chamber, in order to introduce cleaning compressed air into the powder chamber, is provided in a side wall of the powder container.

The invention suggests a spray element 20, in particular for die spraying devices 10, comprising supply means 42 for liquid working medium and, optionally, supply means 50 for control air, an atomizing device 78/80b connected with supply means 42 for working medium and a switch valve 62 controlable in dependence of pressure, said switch valve 62 having a flexibly biassed valve body 68 for alternatively establishing or interrupting the connection between the supply means 42 for working medium and the atomizing device 78/80b. In spray element 20, the valve body 68 is designed as having inherent flexible bias.
摘要:
A recirculating paint supply system supplies single or multiple paint coating to paint spray stations arranged in parallel or series relation, each station including manually operated flexible monoline and coaxial conduits (102, 104) to supply paint to an improved spray gun (88). In one aspect of the invention, the improved spray gun is comprised of a polymeric material to reduce the overall weight of the spray gun thereby reducing operating fatigue and ailments caused by the use of conventional spray guns. In another aspect, the improved spray gun includes larger air passages (338) which provide for a greater volume of air to pass through the spray gun, thereby providing increased atomization of the liquid coating composition. Thus, the reduced weight, as well as the increased atomization, increases the overall finish quality of the object being painted.
