Solution Overview
Problem
Conventional multi-cylinder membrane machines are bulky, heavy, and inflexible, with high material consumption and poor serviceability, requiring extensive space and costly manifold systems, and are difficult to maintain due to complex access to the membrane and valves.
Innovation Solution
A compact design separating the drive unit and delivery unit, with the drive unit optimized independently, using an eccentric crank mechanism and integrated components to reduce size and weight, and allowing for easy membrane and valve replacement without disassembling wetted components, and integrating components like pressure relief valves and degassing valves into the drive unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional multi-cylinder diaphragm machines are designed with integrated drive unit and conveying unit, then structural unity is achieved, but space requirement and weight increase
Solution Approach 1:
The patent divides the diaphragm machine into two separate units: a drive unit containing the crankshaft and connecting rods, and a conveying unit containing the diaphragm heads and valve arrangements. These units are connected via hydraulic lines, allowing the conveying unit to be compact and lightweight while the drive unit can be optimized independently for power transmission.
2Productivity
If conventional designs use extensive manifold systems to connect widely separated diaphragm heads, then fluid distribution is achieved, but material consumption and cost increase
Solution Approach 1:
The patent eliminates the need for extensive manifold systems by directly connecting each diaphragm head to the hydraulic lines. The valve arrangements are integrated into the diaphragm heads themselves, removing the intermediary manifold components and reducing material consumption while maintaining fluid distribution functionality.
3Productivity
If conventional designs have suction and discharge pipes connected to diaphragm heads, then fluid conveyance is achieved, but serviceability deteriorates due to difficult access to wear parts
Solution Approach 1:
The patent designs the conveying unit with modular diaphragm heads that can be independently accessed and serviced. The separation of the drive unit and conveying unit allows technicians to access wear parts such as diaphragms and valves without disconnecting suction and discharge pipes, significantly improving serviceability while maintaining fluid conveyance functionality.

AI summary
The present invention relates to a multi-cylinder diaphragm machine having at least two hydraulically driven diaphragms, comprising: a drive unit (1) for generating at least two pulsed hydraulic fluid flows for driving the diaphragms, and a delivery unit (2) which serves for delivering a delivery medium and has at least two pump chambers, the volumes of which can be varied by the movement of in each case one diaphragm, wherein each delivery chamber is connected via a pressure value to a pressure line and via a suction valve to a suction line. In order to provide a multi-cylinder diaphragm machine which eliminates or at least reduces the stated disadvantages, which is extremely compact and therefore of space-saving and material-saving design, which has high energy efficiency and a high degree of flexibility for adaptation to the conditions at the installation location, and with which it is simultaneously ensured that the individual diaphragms and valves can be mounted and dismounted in a simple manner, it is proposed according to the invention that the delivery unit is composed of a diaphragm body, in which the pressure line and suction line are arranged, and of at least two hydraulic bodies, wherein each hydraulic body is connected to the drive unit, wherein a cavity is formed between each hydraulic body and the diaphragm body, in which cavity one of the diaphragms is arranged such that, as a result of the generation of the pulsed hydraulic fluid flows, the diaphragms are moved within the cavities and a delivery medium is transported periodically from the suction line into the pressure line.
