Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in Fig. 1~5, a kind of single plunger pump convenient for assembling and using, including the pump housing 1, pump head 13 and pump cover 2, pump
One end of the first 13 setting pump housing 1, pump cover 2 are mounted on the top of pump head 13, and the inside of the pump housing 1 is fixedly mounted by electric machine support 17
There is motor 20,20 output end of motor is equipped with pinion gear 19, and the side of pinion gear 19 is fixedly installed with gear wheel 16, gear wheel 16
Side be fixedly installed with eccentric shaft 18, pinion gear 19 is sequentially connected by gear wheel 16 and eccentric shaft 18, the one of eccentric shaft 18
End is fixedly installed with plunger 14, and one end of gear wheel 16 and the both ends of eccentric shaft 18 are symmetrically installed with deep groove ball bearing 15, pump
First 13 side is equipped with water supply connector 12, and one end inside water supply connector 12 is equipped with off-load spool 10, the outside of off-load spool 10
It is arranged with off-load valve spring 11, one end of pump head 13 is equipped with outlet pipe 8, and the side of water supply connector 12 and outlet pipe 8 is pacified respectively
Equipped with one group of O-ring seal 3 and Inlet and outlet water bolt 9, water supply connector 12 is connected with outlet pipe 8, and the two sides outside plunger 14 are set
There is pressure ring 4, and sealed by water seal 5, the side on 2 top of pump cover is equipped with the plug 6 for sealing by plug bolt 7, unloads
The two sides up and down of lotus spool 10 are symmetrically arranged with two groups of check valves 22, are equipped with check valve assembly 21 on the outside of each check valve 22.
Wherein, it is fixedly mounted between pump head 13 and the pump housing 1 by Cross Recess Head Screw 23.
Wherein, external engagement is driven between pinion gear 19 and gear wheel 16, and modulus 0.6-1 reduces components progress
And manufacture difficulty, while improving the transmission efficiency of transmission system.
Wherein, by linear sealing between off-load spool 10 and pump head 13, unloading valve pore size is 1.5-2.5mm, makes inside
Space is more optimized.
Wherein, it is equipped with seal groove on the inside of pressure ring 4, and forms complete cavity, inside cavity setting with plunger 14, pump head 13
O-ring seal 3, when the water seal of reciprocating motion has a small amount of water leakage, which can prevent water along column
The reciprocating motion of plug 14 flows into inside the pump housing 1, and inner body is caused to meet scale erosion etc..
Wherein, it is equipped with lubricant grease 24 in the cavity between plunger 14 and pump head 13, plays lubricating action.
Wherein, two groups of check valves 22 include the first inlet valve, the first outlet valve, the second inlet valve, the second outlet valve.
It should be noted that the present invention is a kind of single plunger pump convenient for assembling and using, when specific works, plunger 14 exists
It realizes and moves back and forth under actuated by cams, there are two the cavity sealed, cavity one and cavitys two respectively at 14 both ends of plunger.Initial shape
There is no water inside state machine, when plunger 14 is from right past left movement, one inner air of cavity is positive pressure, and the first inlet valve is closed,
First outlet valve is opened, and the air inside cavity one is discharged, when plunger 14, which moves to extreme position, to be moved from left to right, chamber
One internal volume of body becomes larger, and forms negative-pressure vacuum, and the first outlet valve is closed, and the first inlet valve is opened, by the sky in water inlet management
Gas continues to suck inside cavity one, as soon as internal gas is discharged cavity two when the sucking of cavity negative pressure, moves in circles
Until the air inside water inlet system is drained, liquid is full of inlet pipeline, realizes function of self water-suction.Plunger 14 is past from the right side at this time
When left movement, one internal liquid of cavity is closed by positive pressure, the first inlet valve, and the first outlet valve is opened, the liquid inside cavity one
Pumped out from water outlet, while forming negative pressure inside cavity two, the second outlet valve close, the second inlet valve open, by liquid from
Water inlet sucks in cavity two.After plunger 14 moves to left end extreme position, cam actuated plunger 14 moves from left to right,
At this moment, it is filled liquid inside cavity two, since plunger 14 is oppressed, switchs to positive pressure, the second inlet valve is closed, and the first outlet valve is beaten
It opens, plunger 14 pumps out the liquid inside cavity two from water outlet, in plunger 14 from left to right motion process, inside cavity one
Pressure becomes negative pressure, and the first outlet valve is closed, and the first inlet valve is opened, by liquid in water inlet sucking cavity one, in this way
Complete a circulation.
When water outlet is blocked by foreign matter leads to pump internal pressure raising more than safety valve setting pressure, safety valve is beaten
It opens, the low-pressure area before being discharged the high pressure water between single valve and water outlet from safety valve aerial drainage to water feeding one-way valve, in protection pump
Portion's pressure is not too high, caused pump configuration damage.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.Wherein "upper" "lower"
" left side " " right side " indicates the noun in orientation.It should be understood by those skilled in the art that the present invention is not limited to the above embodiments,
