FEEDING RESERVOIR FOR THICK MATTER, TWO-CYLINDER PUMP. |
摘要 |
<p>A feeding reservoir for a two-cylinder pump is provided for the pressurized delivery of thick matter. The feeding reservoir includes a material supply port, a front wall having two pump-side ports therein, and a back wall opposite the front wall having two outlet-side ports therein. The pump-side ports lead to the delivery cylinders of the pump, and the outlet-side ports lead to delivery lines. The outlet-side ports are each positioned diametrically opposite to a respective pump-side port, forming two port pairs. A swing pipe is positioned in the reservoir capable of swivelling alternately between one port pair to the other port pair to place the outlet-side port of a port pair in communication with the pump-side port of the port pair. The swing pipe is a straight through-way pipe. Self-adjusting sealing and wearing rings are positioned between the ends of the swing pipe and the pump-side and outlet-side ports for being pressed against the ports under delivery pressure. Spectacle-shaped wearing plates are also positioned at the pump-side ports and at the outlet-side ports. Two radially projecting cover plates are provided at the end of the swing pipe proximate the outlet-side ports for covering the outlet-side port not in communication with the swing pipe to inhibit backflow of the thick matter from the outlet-side port into the feeding reservoir.</p> |
