Abstract
A dish-shaped pump comprises two dish-shaped bodies. Grooves are formed in the peripheries of the dish-shaped bodies and used for mounting O-shaped sealing rings, a concave angle a of each dish-shaped body is smaller than 30 degrees, and a flow guide ditch is formed in the center of each dish-shaped body. The motion range of a diaphragm is decreased by controlling the concave angles a of the dish-shaped bodies without increasing cost, so that the service life of the diaphragm is prolonged, manufacturing processes are not changed, and the dish-shaped pump is easily applied to industries in real work.
Description
Technical field
The utility model relates to a kind of dish-like pump housing.
Background technique
Pulsating jet metering pump (ZL200420068273.1), pulsating diaphragm charging machine (ZL200520052543.4) are in commercial Application, and critical component barrier film is very easily damaged, and this has a strong impact on product performance, has restricted and applied.Experimental study finds there is problem in barrier film fixing device (pump housing) design, and the amplitude that causes barrier film to move back and forth is excessive, causes barrier film cracky.
Summary of the invention
In order to improve barrier film working life, the utility model provides a kind of dish-like pump housing.
The technical solution of the utility model is: the dish-like pump housing is made up of 2 dish-like bodies, and dish-like body periphery is fluted for mounting O-shaped seal ring, and dish-like body concave surface a angle is less than 30 °, and center portion is provided with curb.When installation the periphery of barrier film by 2 dish-like bodies symmetrically to being clipped in the middle of the dish-like pump housing, along dish-like pump housing axis direction up and down or left and right operation, because dish-like body concave surface a angle is less than 30 °, diaphragm movement amplitude diminishes barrier film, the degree of injury of each motion alleviates, life.
The beneficial effects of the utility model are, the dish-like pump housing reduces diaphragm movement amplitude and improves barrier film working life by controlling dish-like body concave surface a angle in the situation that not increasing cost; The utility model, does not change preparation process, in the easy commercial Application of practical work.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is dish-like body sectional view.
Fig. 2 is dish-like body plan view.
Fig. 3 is dish-like pump housing sectional arrangement drawing.
1. O RunddichtringOs in figure, 2. dish-like body, 3. curb, 4. barrier film.
Embodiment
In embodiment illustrated in fig. 2, the dish-like pump housing is made up of 2 dish-like bodies (2), and dish-like body (2) periphery is fluted for mounting O-shaped seal ring (1), and dish-like body (2) concave surface a angle is less than 30 °, and center portion is provided with curb (3).
The periphery of barrier film when installation (4) by 2 dish-like bodies (2) symmetrically to being clipped in the middle of the dish-like pump housing, barrier film (4) along dish-like pump housing axis direction up and down or left and right operation, because dish-like body (2) concave surface a angle is less than 30 °, barrier film (4) motion amplitude diminishes, the degree of injury of each motion alleviates, life.
