Abstract

The invention discloses a diaphragm pump and water treatment equipment, wherein, the diaphragm pump includes a housing and a spacer, the inner wall of the housing is provided with a sealing boss; the spacer is arranged inside the housing, and the isolation The part and the housing are enclosed to form a water chamber; the end of the sealing boss facing the spacer is respectively provided with a matching connection part and a connection hole on the spacer, and the connection part is plugged into In the connecting hole, a first sealing member is provided between the connecting portion and the side wall of the connecting hole, so that the sealing boss is in sealing connection with the spacer, and the sealing boss seals the The water-holding chamber is separated to form a high-pressure chamber and a low-pressure chamber. The technical solution of the invention can improve the reliability 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] Diaphragm pump is a kind of pump that can be used in water treatment equipment. The low-pressure chamber, pressurized chamber and high-pressure chamber are separated in the diaphragm pump by housing, separator and diaphragm. In order to avoid the loss of pressure in the high-pressure chamber caused by the direct connection between the low-pressure chamber and the high-pressure chamber, the low-pressure chamber and the high-pressure chamber need to be isolated by a sealed connection. Such as figure 1 As shown, in the prior art, the sealed connection can be made by inserting the connecting part 300' into the connecting hole 400', and setting a sealing member 500 between the end of the connecting part 300' and the bottom wall of the connecting hole 400' 'accomplish. Wherein, the sealing member 500' ...
