The structural schematic diagram of the fixed frame of the drive mechanism shown.Below with reference to Fig. 1 to Fig. 4, it is described in detail.The utility model provides
A kind of drive mechanism for single plunger double end booster pump, generally, may include motor body 11, motor shaft 12, partially
Mandrel 13 and plunger 2.Plunger 2 is arranged in pump case 9.Plunger 2 is arranged vertically with eccentric shaft 13, and plunger 2 is equipped with U-type groove 21.Partially
Mandrel 13 has first end 131 and second end 132, and the first end 131 of eccentric shaft 13 is connect with 12 interference of motor shaft.Eccentric shaft 13
Second end 132 be adapted and connect with U-type groove 21 by bearing 3 so that plunger 2 is suspended on bearing 3, it may also be said to be bearing
3 size is same or similar with the size of U-type groove 21, so that the U-type groove 21 of plunger 2 is fitted closely with bearing 3, so that plunger 2
Weight supported by bearing 3.Fixed frame 15 is fixedly connected between pump case 9 and motor body 11.Eccentric shaft 13 passes through the second axis
Bearing is held 142 to be mounted on fixed frame 15, the axis of second bearing bearing 142 and the axis of motor shaft 12 and eccentric shaft 13
Axis is consistent.By the way that eccentric shaft 13 and motor shaft 12 are directly connected to, so that without intermediate transmission, compact-sized, transmission
It is high-efficient, also reduce pump housing calorific value.By being fixedly connected with fixed frame 15, and general between pump case 9 and motor body 11
Eccentric shaft 13 is mounted on fixed frame 15 by second bearing bearing 142, so that booster pump 1 is with small vibration, low noise both increased
The comfort of product, and reduce costs.
Specifically, the first end 131 of eccentric shaft 13 has tubular structure, and the tubular structure of first end 131 is connected with interference
Mode be socketed on motor shaft 12.The second end 132 of eccentric shaft 13 is coupled by bearing 3 with U-type groove 21.Wherein, U-type groove 21
Be located at the center of plunger 2 so that its symmetrical configuration so that during plunger 2 carries out a reciprocating, plunger to
The moving distance at both ends is identical, thus make 13 stress equalization of eccentric shaft, it is with small vibration.(i.e. U-type groove 21 is along column for the length of U-type groove 21
Distance on the length direction of plug) it is identical as the outer diameter of bearing 3, so that plunger 2 can be suspended on eccentric shaft 13.Exist simultaneously
Position between the both ends and U-type groove 21 of plunger 2 is respectively arranged with sealing ring 8 so that the pump case 9 of plunger 2 and booster pump it
Between seal.Sealing ring 8 can be sealing structure well-known to those skilled in the art, such as oil sealing sealing, piston ring etc
Sealing structure, as long as can be realized the sealing structure for not influencing the reciprocating motion of plunger 2.Both ends and pressurization in plunger 2
9 contact position of pump case of pump is respectively arranged with booster cavity 6 and booster cavity 7, so that plunger 2, in primary move back and forth, two are pressurized
Chamber 6 (7) realizes imbibition/drain or drain/imbibition function respectively.Primary reciprocating motion of two booster cavities 6 (7) in plunger 2
In work alternatively simultaneously, make its liquid generate pressure oscillation it is smaller, fluid pressure stablize, pulse is small, reduces booster pump
Equipment vibration.Movement while drainage valve may be implemented in the single motion of plunger 2.
As shown in figure 4, being the individual structural schematic diagram of fixed frame 15.Fixed frame 15 includes positioning skirt 151, positioning branch
Bearing bore 152, mounting hole 153 and clamping structure 154.Mounting hole 153 is bolted for fixed frame 15 with motor body 11
Connection.The size for positioning skirt 151 and motor body 11 is adapted, so that positioning 151 fitting sle of skirt is set to motor body 11
On.Second bearing bearing 142 of the installation of positioning support hole 152 for positioning support eccentric shaft 13.The axis in positioning support hole 152
It is consistent with the axis of the axis of motor shaft 12, eccentric shaft 13.Clamping structure 154 is connected and fixed for fixed frame 15 with pump case 9.Value
It is noted that the drive mechanism provided by the utility model for single plunger double end booster pump is by fixed frame 15 by motor
It links together with the pump housing, positioned by the second bearing bearing 142 being mounted in positioning support hole 152 and supports eccentric shaft
13, fixed frame 15 is positioned by the positioning skirt 151 that fitting sle is set on motor body 11, so that positioning support hole 152
Axis it is consistent with the axis of the axis of motor shaft 12, eccentric shaft 13, and make motor 1 operate when, drive mechanism (i.e. motor shaft
12, eccentric shaft 13 etc.) is preferably supported and positioned, to prevent motor shaft 12, eccentric shaft 13 etc. from unnecessary vibration occurs,
So as to significantly reduce the equipment vibration of booster pump.In other words, when mounting hole 153 is bolted to connection, only
Only play the role of linking together fixed frame 15 and motor body 11, and play main positioning support is positioning
Skirt 151 and positioning support hole 152.
Further, positioning on skirt 151 can be set several hollow holes.Hollow hole can both make air circulation in solid
Determine the inside and outside of frame 15, convenient for heat dissipation, and the weight of fixed frame 15 can be reduced, in order to be applied to miniaturization and the hand of booster pump
Hold formula design.
Further, the second bearing bearing of restricted eccentric shaft 13 is arranged close to the side of plunger 2 for positioning support hole 152
142 mobile retention beads 155.After fixed frame 15 is installed, it can by the first end 131 and second bearing of eccentric shaft 13
Bearing 142 is limited in 15 inside of fixed frame, prevents eccentric shaft 13 or second bearing from supporting 142 and moves along its axis direction.
Based on same purpose, chimb is equipped at the first end 131 of eccentric shaft 13.The diameter of chimb is greater than straight near first end 131
Diameter, thus after second bearing bearing 142 is set on eccentric shaft 13, due to the restriction of chimb, so that eccentric shaft 13 will not be from the
It is skidded off in two bearings bearing 142.
A kind of drive mechanism for single plunger double end booster pump provided by the utility model, motor 1 further includes rear end
Lid 14.Eccentric shaft 13 can be set rear end cap 14 either internally or externally.Eccentric shaft 13 is additionally provided with gas vent 133, makes eccentric shaft
13 are easily installed when socket is mounted on motor shaft 12.
In a specific embodiment, the first end 131 of eccentric shaft 13 is arranged inside rear end cap 14, eccentric shaft 13
Middle part by bearing bearing be mounted on rear end cap 14 so that eccentric shaft 13 second end 132 stretch out motor 1 outside after again
It is connect by bearing 3 with the U-type groove of plunger 2.Its structure does not contain intermediate transmission mechanism, so that its is compact-sized, occupied space
It is small, convenient for applying in hand-held booster pump.
In another particular embodiment of the invention, eccentric shaft 13 is arranged outside rear end cap 14.Specifically, motor shaft 12 is logical
First bearing bearing 141 is crossed to be mounted on the center of rear end cap 14 and stretch out outside rear end cap 14.The first end 131 of eccentric shaft 13 is socketed
On motor shaft 12, fixed frame 142 is fixedly connected on rear end cap 14.The middle part of eccentric shaft 13 is mounted directly or by the
Two bearings bearing 142 is mounted on the center of fixed frame 142, so that the axis of the axis of second bearing bearing 142 and motor shaft 12
It is consistent.Second bearing bearing 142 and first bearing bearing 141 design so that motor shaft 12 or eccentric shaft 13 assembly knot
Structure intensity is higher, and without intermediate transmission, vibration is small, improves the comfort of product.
As shown in figure 3, plunger 2 U-type groove 21 width (i.e. perpendicular to U-type groove 21 along the direction of the length direction of plunger
On distance) two sides on direction are reserved with a space 4 and 5 respectively so that the part of bearing 3 can be into when eccentric shaft 13 rotates
Enter in space 4 (5), so that only the needs that lesser 21 size of U-type groove is able to satisfy its reciprocating motion need to be opened up in plunger 2.
