Detailed description of the invention
The following is the specific embodiment of the present invention and combine accompanying drawing, the technical side to the present invention
Case is further described, but the present invention is not limited to these embodiments.
As shown in Figures 1 to 7, this plunger pump of high-pressure airless sprayer include the pump housing 1,
Decelerator 2 and motor 3.
There is in the pump housing 1 feeding-passage 1a and discharging that plunger cavity is connected with plunger cavity
Passage 1b, feeding-passage 1a connects and has the inlet connector 4 of one-way flow, tapping channel
1b is upper connects the discharging joint 5 having one-way flow.
It is provided with piston 6 in plunger cavity, between piston 6 and the pump housing 1, is provided with oil sealing 8 and straight
Bobbin holds 9, it is ensured that sealing and kinetic stability.When this plunger displacement pump runs, piston 6
Axial reciprocating, plunger cavity volume back and forth changes, and when volume increases, plunger cavity produces negative pressure,
Discharging joint 5 is automatically closed, and inlet connector 4 is automatically in unlatching shape
State, the medium such as coating or paint enters in plunger cavity.When volume-diminished, plunger cavity produces
Malleation, discharging joint 5 is automatically in opening, and inlet connector 4 is automatically in
Closed mode, medium is sprayed by discharging joint 5.
Decelerator 2 is planetary reduction gear, and planetary gear uses POM injection mo(u)lding.Decelerator
2 housings are fixing with the housing of the pump housing 1 and motor 3 to be connected.The sun gear of planetary reduction gear
Being fixed on motor 3 main shaft, reducer output shaft 2a penetrates the pump housing 1 and sets between the two
Having bearing 10, this structure had both made more compact structure, improve again plunger displacement pump intensity and
Stability.
It is fixed with swash plate 11 on reducer output shaft 2a, piston 6 is arranged with and makes piston 6
The first spring 12 leant with swash plate 11;The face leant with piston 6 in swash plate 11
It is obliquely installed relative to reducer output shaft 2a;A balance columns also it is equipped with in the pump housing 1
13, balance columns 13 is arranged relative to reducer output shaft 2a centrosymmetry with piston 6,
The second spring 14 making balance columns 13 and swash plate 11 lean it is arranged with on balance columns 13.
Against there being thrust bearing 15 on the face leant with piston 6 in swash plate 11, balance columns 13
All lean with thrust bearing 15 with piston 6.Motor 3 drives swash plate 11 to rotate a circle,
Piston 6 moves back and forth once.
The pump housing 1 is provided with the pressure switch of the discharging cavity pressure for monitoring discharging joint 5
7.Pressure switch 7 and motor 3 all with control circuit electric connection, according to pressure switch 7
Signal control motor 3 rotating speed of feedback, and then ensure coating pressure and the setting ejected
State corresponding and ensure plunger displacement pump safety.
Pressure switch 7 includes pressure valve 7a and microswitch 7b, the one of microswitch 7b
End is hinged with the pump housing 1, also by extension spring 7c phase between microswitch 7b with the pump housing 1
Even.

One end of 7a2 passes the pump housing 1 and can lean with the triggering sheet of microswitch 7b;Valve body 7a1
Fix with the pump housing 1 and be connected and valve seat 7a3 is pressed in the pump housing 1.When discharging joint 5
When discharging cavity pressure raises, sealing ring 7a5 and valve rod 7a2 is promoted to be displaced outwardly and compress
Compression spring 7a4, when pressure reaches certain value, valve rod 7a2 and microswitch 7b touches
Send out sheet lean and then trigger microswitch 7b, this force value it is believed that coating injection pressure
Power setting value.After the discharging cavity pressure of discharging joint 5 declines, compression spring 7a4 pushes away
Rotary packing ring 7a5 and valve rod 7a2 moves inward, and valve rod 7a2 touches with microswitch 7b
Send out sheet to depart from.
Being fixed with knob shell 16 on the pump housing 1, knob shell 16 inner position has a rotation axis
20 and first push rod 17 leant with rotation axis 20 cam part, one first top
Bar 17 is connected with microswitch 7b.By rotary knob axle 20, change the first push rod 17
The length stretched out, and then change microswitch 7b pendulum angle, i.e. opened by regulation fine motion
Close spacing between trigger member and the valve rod 7a2 of pressure valve 7a of 7b, it is achieved adjusting coating
The pressure set points of injection.Specifically, microswitch 7b pendulum angle is the biggest, coating
The pressure set points of injection is the highest, otherwise the least.In microswitch 7b threaded have with
The trimming bolt 7d that first push rod 17 leans, realizes micro-by screwing trimming bolt 7d
Adjust the pressure set points of coating injection.
According to practical situation, pressure switch 7 can directly use pressure transducer;Control electricity
Road controls motor 3 rotating speed neatly according to corresponding actual pressure value and setup pressure value,
It is always ensured that equipment coating spray regime meets setting state and improves the use of plunger displacement pump
Life-span.
The pump housing 1 is provided with the relief valve 18 of the discharging cavity pressure for discharging discharging joint 5.
After shutting down, the discharging cavity pressure of relief valve 18 removal discharging joint 5 can be handled, enter
And just with unload the parts such as spray gun and flexible pipe.One and knob is there is also positioned in knob shell 16
The second push rod 21 that axle 20 cam part leans, the second push rod 21 and relief valve 18
It is connected by connecting rod 19 between valve rod 7a2.By rotary knob axle 20, change push rod
The length stretched out, and then pull the valve rod 7a2 of relief valve 18, it is achieved open relief valve 18;
In practical structures, the pressure set points of operation knob axle 20 adjusting coating injection and pressure release
Direction of rotation is different, and then has easy to operate and have the advantage avoiding maloperation.
