Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 to Fig. 3 is referred to, the utility model provides a kind of high-pressure mini electrical plunger pump, including the pump housing 1 and the pump housing 1
The motor 2 being connected, the motor shaft 201 of the motor 2 is connected with an eccentric wheel 3；Bearing 4 is fixed with outside the eccentric wheel 3；Institute
State to be provided with a plunger hole 5, plunger hole 5 in the pump housing 1 and matched plunger 6 is installed, the length of plunger hole 5 is more than plunger 6
Length；The side of plunger hole 5 is provided with a driver slot 7 matched with bearing 4；The bearing 4 is located in driver slot 7；It is described
A plenum space 8 is formed between plunger hole 5 and plunger 6；The side of the pump housing 1 is provided with the water intaking valve that a plenum space 8 connects
9, opposite side is provided with outlet valve 10；Water flow passage is crossed provided with one in the pump housing 1, outlet valve 10 is by crossing water flow passage and plenum space
8 connect.
The pump housing 1 is provided with a pressure regulator valve 11.
The pump housing 1 is provided with a pressure switch 12.
Sealing gasket 13 is provided between the pump housing 1 and pressure switch 12.
Mutually fixed by motor fixing frame 14 with motor 2 between the pump housing 1.
The eccentric wheel 3 is made up of front-wheel 301 with trailing wheel 302, and front-wheel 301 staggers with trailing wheel 302, front-wheel 301 and trailing wheel
Step 15 is formed between 302；The front-wheel 301 is sheathed on the bearing outside front-wheel 301 with being all arranged with bearing 4 outside trailing wheel 302
4 are fixed by step 15；A bearing fixed mount 16 is provided between the pump housing 1 and motor 2, is sheathed on outside trailing wheel 302
Bearing 4 is fixed by bearing fixed mount 16.
Application method of the present utility model is as follows：
When needing to use plunger pump, first motor 2 can be connected with power supply, then start motor 2, as motor 2 is opened,
The motor shaft 201 of motor 2 can then be rotated, and the eccentric wheel 3 being connected with the motor shaft 201 of motor 2 then can be with motor shaft
201 be that eccentric motion is done in axle center, and the bearing 4 being sheathed on outside eccentric wheel 3 then does eccentric motion therewith, due to bearing 4 and driver slot 7
Match and be located in driver slot 7, driver slot 7 will can be then somebody's turn to do then located at the side of plunger 6, therefore when bearing 4 does eccentric motion
Stock motoricity is acted on plunger 6, realizes the reciprocating motion of plunger 6, when plunger 6 is subjected to displacement towards plenum space 8, supercharging
The volume in space 8 diminishes, and pressure becomes big, and the current now entered by water intaking valve 9 in plenum space 8 can then be made in high pressure
Under, it is squeezed into crossing in water flow passage, is finally output for spraying operation from outlet valve 10 with the state of highly pressurised liquid, with
Plunger 6 it is continuous reciprocal, be continually changing that light water fluidisation can be made into highly pressurised liquid continuous in a steady stream by the volume of plenum space 8
The output pump housing 1 is outer to be used.
Understand in summary, the utility model drives eccentric wheel 3 to realize the reciprocating motion of plunger 6 by motor 2, not only
With powerful driving force, high pressure can be effectively formed, and in the process of running, situation about being engaged in the absence of parts is maximum
Abrasion when parts are used is reduced in degree, service life is extended, can more be prevented due to making an uproar that parts friction is produced
Sound, therefore the utility model just can export highly pressurised liquid without using diaphragm or gear, it is to avoid use insufficient pressure during diaphragm
Noise excessive and easy to wear situation when being exported with gear.
The pump housing 1 is provided with pressure regulator valve 11, the presence of pressure regulator valve 11 can in the case where plunger pump ensures high pressure root
According to actually required adjustment operating pressure, the effect for adapting to different demands is played.
The pump housing 1 is provided with pressure switch 12, and the presence of pressure switch 12 can help plunger pump to realize that closing rifle shuts down,
Reduce and sealing gasket 13 is provided between energy loss, and the pump housing 1 and pressure switch 12, sealing gasket 13 ensure that the pump housing 1 and pressure
The sealing of switch 12, is improved using performance during pressure switch 12.
Mutually fixed by motor fixing frame 14 with motor 2 between the pump housing 1, motor fixing frame 14 plays the work of bridge joint
With, if the pump housing 1 and motor 2 one of them damage, only one of them need to be disassembled and repaired, it appears ten
Divide convenient, without the dismounting of whole plunger pump is repaired, reduce maintenance load.
Eccentric wheel 3 is made up of front-wheel 301 with trailing wheel 302, and front-wheel 301 forms double with being all arranged with bearing 4 outside trailing wheel 302
