Problems solved by technology

For this, a large number of pump units are required, which makes the whole unit expensive
In addition, each pump unit used with a corresponding drive motor requires a certain amount of space
Therefore, in order to pursue a large fluid volume to be pressurized, considerable space is required

Embodiment Construction

[0025] The pump device 1 is used to pump water. It is a water hydraulic machine and comprises a shaft 2 which is rotatable by a motor not shown. The shaft 2 is a through-shaft extending almost the entire length of the pump device 1 . The first rotor 3 a and the second rotor 3 b are fixed to the shaft 2 in the direction of rotation and in the axial direction of the shaft 2 , which refers to the axis of rotation 4 of the shaft 2 .

[0026] The first rotor 3a has a plurality of first pressure chambers 5a. Each pressure chamber 5a is formed by a first cylinder 6a and a first piston 7a which is movable parallel to the axis 4 of the shaft 2 during operation. Thus, the volume of the first pressure chamber 5 a changes between a maximum size and a minimum size during the rotation of the shaft 2 .

[0027] The first swash plate 8a is positioned facing the front of the first rotor 3a. Each first piston 7a is provided with a first slide 9a. The slider 9a is held in contact with the s...

Abstract

A pump device (1) comprising: a shaft (2), rotor means (3a, 3b), port plate means (15a, 15b) and valve plate means (17a, 17b). The rotor device (3a, 3b) comprises a first rotor (3a) and a second rotor (3b), the first rotor (3a) has a first pressure chamber (5a), the second rotor (3b) There is a second pressure chamber (5b), the port plate arrangement (15a, 15b) has a first port plate (15a) and a second port plate (15b), and the valve plate arrangement (17a, 17b) has a first valve plate (17a) and a second valve plate (17b), wherein at least one rotor comprises force generating means (19), said force generating means ( 19) Press the second port plate (15b) against the second valve plate (17b). The pump device of the present invention pressurizes large volumes of fluid, especially water, in a confined space.

Description

technical field [0001] The invention relates to a pump device. In particular, the present invention relates to a water hydraulic pumping device, ie a pumping device with which water can be pumped and with which the water pressure can be increased significantly so that water can be supplied to a reverse osmosis device. Background technique [0002] The pump arrangement comprises a shaft, a rotor arrangement fixed to said shaft in the direction of rotation, said rotor arrangement having a pressure chamber whose volume changes during rotation of said rotor arrangement, port plate arrangement, Said port plate means has a through opening for each of said pressure chambers and is connected in rotational direction to said rotor means, and to a valve plate means cooperating with said port plate means. [0003] In such a pump arrangement, when the shaft is driven in the direction of rotation, the rotor arrangement rotates, thereby increasing and decreasing the volume of the pressure...
