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.
