Abstract

The invention relates to the process of increasing the capacity of circulating pumps where the intake is enhanced, and thereby also the capacity. This is done so that the pump itself powers the ejector in a classic manner, but the ejector intake is not left independent as is usually the case, but is instead connected to the pressure and intake side of the rotor of the circulating pump itself. In this case, the ejector (2) is mounted on the circulating pump (1) which aspirates liquids on the intake side (3) and the pump is on the output (4) and further on the ejector intake (5). The ejector (2), powered in this way, starts aspirating onto its intake (3a) which is connected to the pressure side of the rotor of the circulating pump (6). Also, the intake of the rotor (3a) is connected to the intake side of the rotor (8) of the circulating pump (1 ) thereby increasing its intake. The skew passage (7) enables the regulation of pressure in the entire system. The liquid from the skew passage (7) is connected to the ejector output (8) and is directed on in a single jet.

Description

The process of increasing the capacity of circulating pumps
Area of the invention:
This invention relates to all circulating pumps for water, sea water and light liquids.
Technical problem:
In most cases, circulating pumps have difficulties with the intake itself, so that their capacity is weaker when the intake is weak.
State of the art:
When using circulating pumps, the issue that is generally important is the capacity and the speed of pumping out, like for instance the quantity of water is important for fire fighting pumps, the speed of pumping out is important in flooded houses to reduce the amount of damage, etc. Pumping in and out of a ship's ballast also requires as much sea water to be pumped in over the shortest time period possible. Therefore, by increasing the capacity itself, we can reduce damages and increase the saving of money and time.
Exposition of the essence of the invention:
The procedure of installing an ejector on the pump increases intake, and thereby the capacity. This is done in a way so that the pump itself drives the ejector in a classic way, but the intake of the ejector is not left independent as usual, but is instead linked to the pressure and intake side of the rotor of the circulating pump. Ejector 2 is mounted on the circulating pump 1 which aspirates the liquid on the intake side 3 and the pump is on the ouput 4, and on at the intake of the ejector 5. Powered in this way, the ejector 2 starts aspirating through its intake 3a which is connected to the pressure side of the circulating pump's rotor 6, in the example of realization with four rotors, but depending on how many of them the circulating pump 1 indeed has. Also, the intake of the ejector 3a is connected to the intake of the rotor 8 of the circulating pump 1 , thereby increasing its intake. The skew passage 7 enables the pressure in the entire system to be regulated. The liquid from the skew passage 7, connected to the exit from the ejector 8, is further directed in a single jet.
List of positions:
1 - circulating pump
2 - ejector
3 - intake side
4 - output (exit)
5 - ejector intake (entrance)
6 - pressure side of the rotor of the circulating pump
7 - skew passage
8 - ejector output (exit)

Claims

Claims
1. The process of increasing the capacity of circulating pumps, indicated by the fact that the ejector (2) is mounted on the circulating pump (1) which aspirates liquids on the intake side (3) and the pump is on the exit (4), and further on to the ejector intake (5) whereby the ejector (2) powered in this way starts aspirating onto its intake (3a) which is connected to the pressure side of the circulating pump's rotor (6), while the ejector intake (3a) is connected to the intake of the rotor (8) of the circulating pump (1) thereby increasing its intake.
2. The process of increasing the capacity of circulating pumps according to Claim 1 , indicated by the fact that the skew passage (7) enables the regulation of pressure in the entire system, whereby the liquid from the skew passage (7), connected to the ejector output (8), is directed in a single jet as needed.
