Abstract
A device for an intermittent application of a lubrication or a separation liquid to a component part of a glass-forming machine engageable with molten glass, includes an intermittently driven high-pressure pump and a spraying nozzle connected to the pump by a pressure conduit to apply momentarily a cone of atomized lubrication or separation liquid on the machine part at a pressure of at least 100 bars.
Claims16
A method of an intermittent application of a lubrication or separation liquid without admixture of a carrier gas on at least one part of a glass-forming machine prior to its contact with the processed molten glass, such as shearing blades for shearing gobs off a glass strand, a gravity tube or a chute for guiding glass gobs, a mold, a mold part or a press plunger, comprising the steps of momentarily compressing the lubrication or separation liquid to a pressure exceeding 100 bar;
- then atomizing the compressed liquid;
- and applying a cone of the atomized liquid onto said machine part.
A device for an intermittent application of a lubrication or separation liquid on at least one part of a glass-forming machine prior to its contact with the processed molten glass, such as shearing blades for shearing gobs off a glass strand, a gravity tube or a chute for guiding glass gobs, a mold, a mold part or a press plunger, the device comprising at least one pressing pump for delivering the lubricating or separating liquid at a pressure exceeding 100 bar;
- a means for intermittently driving said pump;
- a high-pressure conduit connected to the outlet of said pump;
- a spraying nozzle connected to said high-pressure conduit for applying a cone of atomized lubrication or separation liquid on said machine part, and wherein said driving means includes a solenoid having an armature in driving connection with said pressing pump, a discharging circuit including a series connection of a capacitor, of a winding of said solenoid and of an electrical controllable switching element, a power-supply circuit for charging said capacitor, and an electrical control circuit for intermittently triggering the switching element in said discharging circuit.
