Apparatus for the metered delivery of a plurality of partial amounts of viscous substances, such as casting resin

摘要

The present invention relates to an apparatus for the metered delivery of a plurality of partial amounts of viscous substances, such as casting resin, having a device for preparing and delivering the viscous substance, preferably comprising two or more resin constituents reacting with one another with the effect of curing, to a plurality of identically designed metering pumps which are arranged next to one another and can be actuated by means of a common actuating bridge. The outlet openings of the said pumps are arranged within a vacuum or negative-pressure chamber above receiving tanks for the partial amounts of viscous substance. The said pumps are also arranged downstream of the device for preparing and delivering the viscous substance, with a branching device interposed, the branching device comprising a manifold bar which is arranged parallel to the row of metering pumps and has for each metering pump a dedicated non-return valve. The metering pumps have a centrally controlled electronic linear drive and are of a modular construction.
