Abstract
The utility model discloses a membrane booster pump capable of preventing mutual folding friction of a membrane piece itself. The membrane booster pump comprises a pump chamber cover, a connecting screw, a one-way valve block base, a boosting piston fixing screw, a boosting piston, the membrane piece, a membrane piece bearing frame, a piston swing frame, a motor bearing end cover and a motor, wherein the membrane piece is installed on the membrane piece bearing frame and the membrane piece bearing frame is installed on the motor bearing end cover. The membrane booster pump is characterized in that an annular convex edge is arranged at the outer edge of the back face of the membrane piece, an annular groove is formed in the front face of the membrane piece bearing frame and the annular convex edge is located inside the annular groove. The membrane booster pump has the advantage of preventing mutual folding friction of the membrane piece itself.
Description
Technical field
The utility model relates to a kind of suction booster, and specifically a kind of have a diaphragm booster pump that prevents the mutual doubling of diaphragm self friction.
Background technique
At present, known diaphragm booster pump mainly forms (as shown in Figure 1) by pump chamber lid 1, connecting screw 2, one-way valve bar 3, charged piston retaining screw 4, charged piston 5, diaphragm 6, diaphragm bearing support 7, piston rocking carrier 8, motor bearing end cover 9 and motor 10.The back side of the diaphragm that the manufacturer of overwhelming majority diaphragm booster pump is designed and the front of diaphragm bearing support are all smooth straight (as shown in Figure 2), when suction booster turns round, because the back side of diaphragm and the front of diaphragm bearing support are all smooth straight, there is no the concavo-convex protection interlocked, under the effect of the tractive force back and forth of rocking carrier, as easy as rolling off a logly supercharging is waved to the outer diaphragm of regional boundary draw in supercharging and wave in district, yet after drawing in, but can't automatically exit diaphragm, the limited space in district is waved in supercharging in addition, diaphragm can't free activity produce the phenomenon of self mutual doubling friction, slightly long diaphragm of time will tear rotten because of self mutual doubling friction.
Summary of the invention
The purpose of this utility model is to provide a kind of diaphragm booster pump that prevents the mutual doubling friction of diaphragm self that has.
The purpose of this utility model is achieved through the following technical solutions.
A kind of have a diaphragm booster pump that prevents the mutual doubling of diaphragm self friction, comprise pump chamber lid, connecting screw, one-way valve bar, charged piston retaining screw, charged piston, diaphragm, diaphragm bearing support, piston rocking carrier, motor bearing end cover and motor, diaphragm is arranged on the diaphragm bearing support, the diaphragm bearing support is arranged on motor bearing end cover, it is characterized in that: the outer edge at the described diaphragm back side is provided with an annular nib, the front of diaphragm bearing support is provided with an annular groove, and annular nib is positioned at annular groove.
The utility model compared with prior art has the following advantages.
The utility model is because the outer edge at the diaphragm back side is provided with an annular nib, and when mounted, annular nib just is placed in the set annular groove in the front of diaphragm bearing support, forms the concavo-convex effect interlocked.Effectively prevent suction booster when running, under the effect of drawing back and forth at rocking carrier, supercharging is waved to the outer diaphragm of regional boundary and draw in supercharging and wave in district and produce the phenomenon of mutual doubling friction, thereby extended its working life.Have easy for installation, the advantage that technique is simple, practical and reliable.

Embodiment
Below in conjunction with accompanying drawing, to the utlity model has the diaphragm booster pump that prevents the mutual doubling friction of diaphragm self, be described in further detail.
As shown in Figures 1 to 8, the utlity model has the diaphragm booster pump that prevents the mutual doubling friction of diaphragm self and comprise pump chamber cap 1, connecting screw 2, one-way valve bar 3, charged piston retaining screw 4, charged piston 5, diaphragm 6, diaphragm bearing support 7, piston rocking carrier 8, motor bearing end cover 9 and motor 10.Diaphragm is arranged on the diaphragm bearing support, and the diaphragm bearing support is arranged on motor bearing end cover, and the outer edge at the diaphragm back side is provided with an annular nib 11, and the front of diaphragm bearing support is provided with an annular groove 12, and annular nib is positioned at annular groove.The utility model is because the outer edge at the diaphragm back side is provided with an annular nib, and when mounted, annular nib just is placed in the set annular groove in the front of diaphragm bearing support, forms the concavo-convex effect interlocked.Effectively prevent suction booster when running, under the effect of drawing back and forth at rocking carrier, supercharging is waved to the outer diaphragm of regional boundary and draw in supercharging and wave in district and produce the phenomenon of mutual doubling friction, thereby extended its working life.Have easy for installation, the advantage that technique is simple, practical and reliable.
