Problems solved by technology

However, when the thickness of the integrated diaphragm is small, the shape of the boss structure will be greatly restricted. When the thickness of the integrated diaphragm increases, the resistance during the working process of the diaphragm pump will increase. In summary As mentioned, the performance of this kind of diaphragm pump with integrated diaphragm is poor

Abstract

The invention discloses a diaphragm pump and water treatment equipment. The diaphragm pump comprises a shell, a diaphragm and a piston, wherein a cavity in the shell forms a diaphragm chamber and a power chamber; the diaphragm is isolated between the power chamber and the diaphragm chamber, part of one side, towards the diaphragm chamber, of the diaphragm is formed a containing part; a containingcavity is formed in the containing part; the piston is arranged in the diaphragm chamber, the piston comprises a connecting part; and the connecting part is accommodated in the containing cavity. According to the technical scheme, the diaphragm pump and the water treatment equipment can improve the performance of the diaphragm pump.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a diaphragm pump and water treatment equipment. Background technique [0002] A diaphragm pump is a type of pump used in water treatment equipment to increase water pressure. In one type of diaphragm pump, the piston is fixed by screws, and a screw hole is opened on the diaphragm. In order to avoid the risk of internal leakage of the diaphragm pump caused by the screw hole, in another type of diaphragm pump, an integrated diaphragm is adopted, and the piston It is designed as a boss structure on the diaphragm, and there is no opening on the diaphragm, thereby preventing the liquid in the diaphragm chamber from leaking into the power chamber and affecting the normal operation of the diaphragm pump. However, when the thickness of the integrated diaphragm is small, the shape of the boss structure will be greatly restricted. When the thickness of the integrated diaphragm increas...
