Summary of the invention
For solving the defective and the deficiency of atomizer pump in the prior art, provide the high voltage oil-free small-sized plunger pump of a kind of no any lubricant oil simple in structure, high efficiency or grease.
For addressing the above problem, high voltage oil-free small-sized plunger pump of the present invention, comprise a pump housing and a pump head, pump head is installed on the pump housing, one motor is installed on the pump housing, motor stretches out a motor shaft, it is characterized in that: connect an eccentric mounting in described motor shaft end, secure fit one bearing on the protruding axle in eccentric mounting upper end, cooperate a connecting rod at described bearing top circle, the hinged plunger of connecting rod one end, plunger bushing is in the cavity of the pump housing, at plunger and pump housing contacting point one plunger bushing is set also, each bindiny mechanism in the described pump housing all adopts no oily measure setting.
High voltage oil-free small-sized plunger pump of the present invention also comprises and has a following feature:
Described connecting rod is made up of a collar and a loop bar, and collar fixed cover is on bearing top circle, and the cover boom end has a through hole;
Described plunger end has a connecting head, has an open recess in the neutral position, cross section of connecting head, has a through hole in the open recess position;
Described connecting rod loop bar is inserted in the open recess of plunger connecting head, and cover boom end through hole and connecting head through hole are in coaxial position, and a hinge bar is set in two through hole, and connecting rod and plunger are hinged by hinge bar;
Also be provided with water shutoff circle and pad at described plunger near pump head end position.
Compared with prior art, high voltage oil-free small-sized plunger pump of the present invention adopts rod hinge connection plunger connection mode, adopt no oily measure between its plunger and the plunger bushing, plunger also adopts no oily measure in the activity of pump head, no oil processing is all adopted in whole pump housing inside, having made things convenient for greatly and installed and maintenance, avoided the befouling environment that causes because of leakage of oil, is a kind of no oil piston pump of environment protection type therefore.

Embodiment
Below in conjunction with the drawings and specific embodiments high voltage oil-free small-sized plunger pump of the present invention is described further:
As shown in Figures 1 to 4, high voltage oil-free small-sized plunger pump of the present invention comprises a pump housing 10 and a pump head 20, pump head 20 is installed on the pump housing 10, one motor is installed on the pump housing 10, motor stretches out a motor shaft 1, connect an eccentric mounting 11 in motor shaft 1 end, eccentric mounting 11 closely cooperates mutually with motor shaft 1, secure fit one bearing 12 on the protruding axle in eccentric mounting 11 upper ends, bearing 12 is enclosed within the protruding axle in eccentric mounting 11 upper ends and goes up and fix with protruding axle, protruding axle and eccentric mounting 11 inner circles are in the eccentric shaft position, and the rotation of motor shaft 1 drives eccentric mounting 11 and makes synchronous eccentric rotary.
As shown in Figures 1 to 4, fixed cover one connecting rod 13 on bearing 12 cylindricals, connecting rod 13 is made up of a collar 131 and a loop bar 132, and the collar 131 fixed covers are provided with a through hole 133 in the end of loop bar 132 on bearing 12 cylindricals.
As shown in Figures 1 to 4, the hinged plunger 14 of connecting rod 13 1 ends, plunger 14 is enclosed within the cavity of the pump housing 10, plunger 14 ends have a connecting head 141, the diameter of connecting head 141 is bigger than plunger 14 diameters, have an open recess 142 in the neutral position, cross section of connecting head 141, have a through hole 143 on the open recess 142.The loop bar 132 of connecting rod 13 packs in the open recess 142, and through hole 133 is identical with through hole 134 diameters and be in same shaft core position, in through hole 133 and through hole 143 hinge bar 15 is set, and connecting rod 13 is hinged by hinge bar 15 with plunger 14.Cavity contacting point at the plunger 14 and the pump housing 10 also is provided with a plunger bushing 16, and plunger bushing 16 is made for plastic materials, is provided with for nothing oil between plunger 14 and the plunger bushing 16.Also be provided with water shutoff circle 21 and pad 22 at plunger 16 near pump head 20 end positions, water shutoff circle 21 and pad 22 are for to prevent that the water in the pump head 20 from entering in the pump housing 10.
As shown in Figures 1 to 4, when work, motor shaft 1 drives eccentric mounting 11 and makes eccentric rotary, the motion drivening rod 13 of eccentric mounting 11 is also done eccentric motion, because connecting rod 13 is hinged with plunger 14, the eccentric motion of connecting rod 13 promotes plunger 14 and does left and right sides straight line motion, owing between connecting rod 13 and eccentric mounting 11, be provided with bearing 12, so just reduced the frictional loss of each attachment portion greatly, its fricative heat is also few, therefore can be for there not being oil setting.Mutual fricative heat between plunger 14 and the plunger bushing 16 is also few, and it all can adopt does not have oil setting.Plunger 14 is provided with water shutoff circle 21 and pad 22, therefore can finely play a seal action.Plunger 14 in pump head 20 working principle and the structure of pump head 20 be prior art, no longer be further described here.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
