  • Publication number: 20230184237
    Abstract: A transmission assembly for a pump head of a six-cylinder opposed balanced diaphragm booster pump, a pump head of a diaphragm booster pump, and a diaphragm booster pump. The transmission assembly includes an eccentric assembly, a balance wheel assembly, a bearing and swing arms fixed to the balance wheel assembly. The eccentric assembly includes a motor shaft and eccentric wheels, wherein the movement of two eccentric wheels with a phase difference of 180° drives balance wheels of the balance wheel assembly to move oppositely. The eccentric assembly includes a first eccentric wheel, a second eccentric wheel and a third eccentric wheel in sequence, wherein the first eccentric wheel and the third eccentric wheel are similarly eccentric, and the second eccentric wheel is eccentric in an opposite manner to the first eccentric wheel and the third eccentric. The embodiments reduce noise caused by vibration of an existing diaphragm pump in operation.

  • Publication number: 20230151804
    Abstract: A pump head of a diaphragm booster pump, a diaphragm booster pump, a water treatment device and a method of operating a pump head. The pump head includes: a piston chamber, including a booster chamber arranged on an inner wall of the piston chamber; and a diaphragm, the booster chamber formed through enclosing the diaphragm, and the booster chamber radially expanding or compressing. The movement of two eccentric wheels with a phase difference of 180° in an eccentric assembly drives balance wheels of a balance wheel assembly to move oppositely. During rotation of the eccentric assembly, eccentric forces counteract each other, and the moment keeps balanced. The balance wheel assembly includes big small balance wheels, which are a first small balance wheel, the big balance wheel and a second small balance wheel in sequence, and the eccentric assembly drives the balance wheel assembly to swing eccentrically through a bearing.
