Embodiment Construction

[0034] figure 1 A perspective cutaway view of an embodiment of a discharge head for a vertical pump according to the invention is shown. The discharge head is generally indicated by reference numeral 10 . figure 2 A sectional view of an embodiment of a vertical pump according to the invention is shown, denoted as a whole by the reference number 1 and comprising a discharge head 10 according to the invention.

[0035] In the following description, reference is made by way of example to the important application, namely, that the vertical pump is designed and suitable for use in a solar energy system which utilizes molten salt as heat transfer fluid (HTF) or as heat storage accordingly Fluid concentrated solar power (CSP) systems. More specifically, in this example, a vertical pump is mounted to the tank for the molten salt, eg, to the lid of the tank, and conveys the molten salt from the tank to other locations in the concentrated solar system. Of course, the vertical pump ...

Abstract

A discharge head for a vertical pump includes a base plate configured to mount the discharge head, a top plate, at least one support member connecting the base plate with the top plate, a discharge pipe with an outlet configured to deliver a fluid, and an inner tube. The discharge pipe extends through the base plate. The inner tube is configured to receive a shaft that connects a drive unit with an impeller of the vertical pump, and extends in an axial direction and coaxially within the discharge pipe in a region of the base plate, passing through a wall of the discharge pipe at an intersection, and further extending to the top plate. The inner tube includes a bellows member disposed between the intersection and the top plate. Besides, the invention further provides a vertical pump having the discharge head.

Description

technical field [0001] The invention relates to a discharge head for a vertical pump and to a vertical pump according to the preambles of the respective device independent claims. Background technique [0002] Vertical pumps have been used successfully in a variety of applications for a long time. Vertical pumps for specific applications are usually manufactured according to the specific requirements of the user or matched in detail to specific needs. Vertical pumps can be designed as single-stage pumps and multi-stage pumps. They are usually immersed in the liquid container to be pumped, so that at least the intake or suction bell mouth and the adjoining pump rotor are immersed in the fluid to be pumped, whereby the pump is immediately ready for operation. [0003] An increasingly important field of use for vertical pumps is the generation of energy from solar systems, especially concentrated solar power (CSP) systems. These systems use mirrors or lenses to focus sunligh...
