Problems solved by technology
[0004] However, in the existing pressure-stabilizing pump, the base is slightly deformed by the extrusion of the screw, resulting in a gap between the diaphragm and the diaphragm pressure plate when the diaphragm reciprocates with the swash plate assembly, which reduces the sealing of the booster chamber. Insufficient water blocking pressure of the stabilized pump, rapid flow decay, and short life of the diaphragm

Embodiment 1
[0032] This embodiment provides a diaphragm 1 that is applied to a pressure-stabilizing pump to ensure that the pressure-increasing chamber of the pressure-stabilizing pump has good sealing properties and can output constant and reliable water pressure. This embodiment also provides a constant pressure pump provided with the above-mentioned diaphragm 1.
[0033] See figure 1 , figure 1 Shown is a stabilized pump provided with a diaphragm 1 provided in this embodiment. It also includes a base 2, a pump cover 3, and a diaphragm pressure plate 4. The diaphragm pressure plate 4 and the diaphragm 1 are located between the base 2 and the pump cover 3. The cover 3 is installed on the base 2 by fasteners 6 (for example, screws), and a pressurizing chamber A is formed between the diaphragm pressing plate 4 and the diaphragm 1. The swash plate assembly 5 is placed in the base 2, and the swing head of the swash plate assembly 5 is tightly connected with the diaphragm 1. The swash plate asse...

The invention discloses a stabilized pressure pump and a diaphragm for a stabilized pressure pump and belongs to the technical field of water purifier equipment. the diaphragm for the stabilized pressure pump comprises a diaphragm body and a boss arranged in the middle of the diaphragm body; the outer outline of the lower surface of the boss is adapted to the outer outline of a diaphragm platen matched with the boss for use; and the boss is gradually shrunk in a direction far away from the diaphragm body. The diaphragm can improve the leakproofness of a booster cavity of the diaphragm pump. With the adoption of the diaphragm, the stabilized pressure pump has good sealability and stability, high efficiency and low maintenance cost and is suitable for wide popularization and application.
Description
Technical field [0001] The invention relates to the technical field of water purification equipment, and in particular to a diaphragm for a stabilized pump and a stabilized pump provided with the diaphragm. Background technique [0002] At present, with the improvement of living standards, drinking water health has become the focus of people's attention, and more and more water purifiers are entering ordinary households. As the core component of the water purifier, the stabilized pump is used to ensure constant and reliable water pressure to ensure the reliable operation of the RO membrane, so that the water purifier can produce high-quality drinking water. [0003] Generally, a stabilized pump includes a base, a pump cover, a diaphragm, a diaphragm pressure plate, and a swash plate assembly. The pump cover is locked on the base by screws to complete the cover. The diaphragm and diaphragm pressure plate are located between the base and the pump cover. The compression deformation i...
