Specific embodiment
The embodiments of the present invention are further described with reference to the accompanying drawing.
As shown in figure 1-9
A kind of pump unit for jetting machine, comprising: plunger unit 1, plunger unit 1 include plunger body 11, plunger
One end of body 11 is water inlet end 11.1, and the other end of plunger body 11 is water outlet 11.2,
The first embodiment of plunger unit is to correspond to be equipped at water inlet end 11.1 for limiting water flow by outer in shell 2
The feed liquor check valve 8 that portion is unidirectionally inputted to water inlet end, correspond in the shell 2 be equipped at water outlet 11.2 for limit water flow by
What water outlet unidirectionally exported outward goes out liquid check valve 9.
The working principle of the first embodiment of plunger unit are as follows: 7
External water is entered by inlet opening 23, and inlet opening 23 is entered in intake antrum 6 by feed liquor check valve 8, eccentric
Mechanism rotate driving eccentric block 31 rotates, and plunger body 11 has the driving of eccentric block 31 to move reciprocatingly, the water outlet of plunger body 11
Water at 11.2 is compressed, and is exported by going out liquid check valve 9 from water outlet 22, and elasticity is equipped between plunger body and shell and is returned
Copy, elastic recovery part make plunger body 11 offset with eccentric block 31 for providing elastic force.
Second of embodiment of plunger unit 1, which is that plunger body 11 is hollow, is equipped with limbers 11.3, is equipped in limbers 11.3
Installation cavity 11.4, setting is for limiting water flow by water inlet end 11.1 towards the unidirectional of 11.2 one-way flow of water outlet in installation cavity 11.4
Structure, check configuration include valve plate 11.5, valve deck 11.6, the first elastic component 11.7, valve seat 11.8, and valve plate 11.5 is equipped with and water flowing
The hole that hole 11.3 is connected to, the first elastic component 11.7 are arranged between valve deck 11.6 and valve seat 11.8, and the first elastic component 11.7 will
11.6 elasticity of valve deck is pressed on the hole of valve plate 11.5, and the peripheral wall of valve seat 11.8 is equipped with through slot 11.9, when the water of water inlet end 11.1
When pressing the sum of the pressure of the hydraulic pressure and the first elastic component 11.7 that increase and be greater than water outlet 11.2, valve deck 11.6 is with respect to valve plate 11.5
Movement simultaneously opens hole, and the water through hole of water inlet end 11.1 passes through through slot 11.9 again and flow to water outlet 11.2.
Plunger unit cancels the structure of water feeding one-way valve, check configuration is arranged in plunger unit, so that structure is whole
It is more compact, saved manufacturing cost, simplify water route so that structure design is more reasonable,
The working principle of second of embodiment of plunger unit are as follows:
When eccentric block 31, which is turned to, to offset with plunger body 11 and plunger body 11 is driven to move towards water outlet 11.2, water outlet
11.2 space is compressed, and when the hydraulic pressure of water outlet 11.2 is greater than the threshold value of water one-way valve 5, is passed through by compressed water
Water one-way valve 5 exports high pressure water outward out, while the hydraulic pressure of water outlet 11.2 and the sum of the elastic force of the first elastic component 11.7 are greater than
The hydraulic pressure of water inlet end 11.1, valve deck 11.6 separate limbers 11.3, and water flow can not enter water inlet end 11.1 from water outlet 11.2
It is interior, while the space of water inlet end 11.1 increases, external water supplements water inlet end 11.1；
When eccentric block 31 is turned to 11 disconnecting process of plunger body, the second elastic component 4 pushes plunger body toward water inlet end
11.1 push, and the space of water outlet 11.2 is replied, and the hydraulic pressure of water outlet 11.2 reduces, when the hydraulic pressure and the first bullet of water outlet 11.2
Property part 11.7 the sum of elastic force be less than the hydraulic pressure of water inlet end 11.1, valve deck 11.6 is removed with respect to limbers 11.3, and water flow is from water inlet
End 11.1 enters in water outlet 11.2, supplements the water in water outlet 11.2；
In plunger body reciprocating motion, increases and compress to the space cycle of water outlet 11.2, so that water flow enters water outlet
It is compressed behind end 11.2 and is exported from water one-way valve 5 out, simultaneously as check configuration is arranged inside plunger body 11, water inlet end
11.1 space moves back and forth also with plunger body 11 and cyclically increases and compress, and increases in the space of water inlet end 11.1, i.e.,
When plunger body compresses the water of water outlet 11.2, the hydraulic pressure of water inlet end 11.1 reduces, external water flow can in time into
Water end (W.E.) 11.1 is supplemented, and when plunger body is mobile relative to water inlet end 11.1, the space of water inlet end 11.1 reduces, water inlet end
11.1 water flow is compressed, and pressurized water flow is pushed check configuration open and supplemented the water of water outlet 11.2, water inlet end
11.1 space cyclically increases and reduces with the reciprocating motion of 11 body of plunger, can make water inlet end 11.1 water energy and
When supplemented, and be more rapidly introduced at water outlet 11.2 so that the operation of plunger pump is more steady, hydraulic pressure
It is bigger.
