Problems solved by technology
[0002] At present, the commonly used high-flow booster pumps use a three-chamber (three compression chambers) structure and a double-head pump structure. The structure of the three-chamber booster pump has great limitations, making its work efficiency relatively low and waste energy; moreover, when it is necessary to increase the flow rate, it can only be realized by increasing the motor speed or increasing the eccentric wheel angle; however, these two methods will increase the vibration and noise of the diaphragm pump
The double-head pump is based on the three-chamber, and a pump head is added at the other end of the motor. The pump heads of this structure are far apart, and the connection between the pump heads leads to complicated pipelines.
Easy to form resonance and cause loud noise

Embodiment Construction
[0010] Please refer to 1 to figure 2 , the present invention is a booster pump 1, which includes a first pump housing 10 with a water inlet chamber 11, a first housing bracket 20, a second housing bracket 30, a second pump housing 40 with a water outlet chamber 44, the first The pump housing 10 is installed together with the first housing bracket 20 to form a suction chamber (not indicated), the second housing bracket 30 is installed together with the second pump housing 40 to form a discharge chamber (not indicated), and the first housing bracket 20 and the second Shell brackets 30 fit together to form a transition chamber (not shown).
[0011] In the transition cavity, there are a first bearing 51, a rotating shaft 52 positioned in the first bearing 51, a cam 53 between the first bearing 51 and the rotating shaft 52, and a bearing frame 54 for fixing the first bearing 51. In the suction chamber, there is a first diaphragm 21 close to the first shell bracket 20, a first pis...

A booster pump comprises a first pump shell, a first shell support, a second shell support and a second pump shell, wherein the first pump shell is provided with a water inlet cavity, and the second pump shell is provided with a water outlet cavity. The first pump shell and the first shell support are installed together to form a suction cavity, the second shell support and the second pump shell are installed together to form a discharge cavity, and the first shell support and the second shell support are installed together to form a transitional cavity. A first bearing and a rotary shaft located in the first bearing are arranged in the transitional cavity. A first middle plate, a first suction valve and a first discharge valve are arranged in the suction cavity, wherein the first suction valve and the first discharge valve are respectively installed on the two sides of the first middle plate. A second middle plate, a second suction valve and a second discharge valve are arranged in the discharge cavity, wherein the second suction valve and the second discharge valve are respectively installed on the two sides of the second middle plate. Compared with the prior art, the booster pump has the advantages that two times of circulation between the first suction cavity and the second discharge valve, and between the second suction valve and the first discharge valve can be accomplished in one cycle of the rotary shaft, and the flow rate of the booster pump is increased on the premise that the size of the booster pump is not overly increased.

The double-head pump is based on the three-chamber, and a pump head is added at the other end of the motor. The pump heads of this structure are far apart, and the connection between the pump heads leads to complicated pipelines. It is easy to form resonance and cause loud noise. [0003] Therefore, it is necessary to provide a new booster pump to overcome the above problem...
