[0022] The diaphragm (1.4, 11.4) is made of a rubber or flexible material and is a tubular diaphragm. The middle part is a cylinder with two open ends. There are annular diaphragm belts perpendicular to the cylinder at both ends. There is a flange similar to an O-ring on the outermost diameter for sealing.
[0023] The potential energy diaphragm tank (1) comprises a potential energy lower opening (1.1), a potential energy lower cover (1.2), a potential energy tank body (1.3), a potential energy diaphragm (1.4), a potential energy upper cover (1.5), and a potential energy upper opening (1.6). The potential energy diaphragm tank body (1.3) is connected to the potential energy upper and lower covers (1.5, 1.2) respectively. The connection part clamps the outer annular belt of the potential energy diaphragm (1.4) and fixes it. The diaphragm tank body (1.3) is barrel-shaped and uses a tubular diaphragm.

The low-pressure slurry enters the inner space (C) of the delivery diaphragm tank (11) from the delivery port (11.1), allowing the delivery diaphragm (11.4) to expand outward, and the driving fluid in the outer space (D) pushes the piston (13.2, 3.2) and the piston rod (3.3) to move downward through the delivery pipe (12), pushing the driving fluid in the potential energy cylinder F space into the outer space (B) of the potential energy diaphragm tank (1). The driving fluid compresses the potential energy diaphragm (1.4), and the slurry in the inner space (A) is discharged through the port (1.1), and the energy at the potential energy end is transferred to the delivery end. The two cylinders (3, 13) have different inner diameters, realizing the conversion and delivery of different flow rates and pressures at the two ends. The three systems are used at an interval of 120 degrees, and can continuously enter and discharge slurry.
