Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.But the purposes of these exemplary embodiments
Only it is used for enumerating the utility model with purpose, any type of any limit not is constituted to the real protection scope of the utility model
It is fixed, it is more non-that the scope of protection of the utility model is confined to this.
As shown in Figure 1, the utility model provides a kind of oil pump, including the pump housing 9,9 upper end of the pump housing connects upper cover plate 4, pump
9 lower end of body connects lower cover 5, and upper cover plate 4 is equipped with oil outlet 18, and lower cover 5 is equipped with oil inlet 19, and upper cover plate 4 and lower cover 5 are
Concave shape, upper cover plate 4 and lower cover 5 are connected by standing screw 14, form a cavity, the pump housing 9 are fixed in cavity, and pump
9 upper and lower ends of body are closely buckled in cavity, and upper and lower ends are equipped with pump housing sealing ring 10 in the pump housing, make the pump housing 9 and upper cover plate 4 under
Cover board 5 connects more reliable, good seal performance, and the locking of standing screw 14 is used for the pump housing 9.Oil outlet 18 is connected on the left of 9 upper end of the pump housing,
Oil inlet 19 is connected on the left of 9 lower end of the pump housing, when the pump housing moves up and down, fluid is flowed by oil inlet 19, is flowed out from oil outlet 18.
The pump housing 9 is installed with pump axis 1, and 1 both sides of pump axis in the pump housing 9 are separately connected pump housing piston 6,6 one end of pump housing piston
It is cased with piston O-ring 11, pump axis 1 can drive pump housing piston 6 to move up and down when rotating, and piston O-ring 11 is conducive on piston
Lower movement, reduces movable abrasion, there is movable lower beam 8 between pump housing piston 6 and pump axis 1, movable lower beam 8 and pump axis 1 it
Between be equipped with piston connect sealing ring 12；Strengthen the sealing performance between 9 piston of movable lower beam 8 and the pump housing.Movable lower beam 8 is located at
Between movable upper boom 7 and pump axis 1, movable lower beam 8 gradually thickens from top to bottom, to when pump housing piston 6 moves up and down, flow
Body is flowed by the gap of pump housing piston 6 and movable lower beam 8.
It pumps axis 1 and runs through connecting cover plate 2, connecting plate 3, upper cover plate 4 and lower cover 5,4 face on upper cover plate pumps under axis 1
The movable lower beam plug 17 in embedded one of 8 inside of movable lower beam of side, connection connecting plate 3 are fixed on upper cover plate by standing screw 14
4, connecting plate 3 is equipped with connecting cover plate 2, and two cavitys up and down, the upper cavity are formed with pump axis 1 in 3 container of connecting plate
Interior to be equipped with thrust roller bearing 16, due to the force effect of thrust roller bearing 16, pump axis 1 can be more reliable and more stable when rotating.
It is equipped with movable upper boom 7 in lower chamber, Teflon lubricating sleeve 15 is embedded between movable upper boom 7 and pump axis 1, for filling up activity
Gap caused by lower beam, when pumping the rotation of axis 1, fluid cannot be introduced into inside connecting plate 3, ensure that pump axis 1 and activity
Leakproofness between upper boom 7, and it is respectively equipped with motion bar sealing ring 13 between pump axis 1 and upper cover plate 4 and lower cover 5.
Its course of work is as follows：When pumping the rotation of axis 1, drives pump housing piston 6 to move up and down and move back and forth, it is specific to move
As：When initial, pump housing piston 6 is in 9 middle part of the pump housing and is close to movable lower beam 8, under the action of being flexibly connected sealing ring 12
About 6 two cavity of pump housing piston can not be connected to.When pump housing piston 6 up moves, cause to be formed in the cavity of 6 lower section of pump housing piston
Negative pressure, the cavity of 6 top of pump housing piston is interior to form positive pressure, and 6 promotion activity upper boom of pump housing piston, 7 uplink, fluid is by oil inlet 19
By the channel between pump housing piston 6 and movable lower beam 8 in into the pump housing 9, the cavity divided on pump housing piston 6 is flowed into, is being pumped
Under the promotion of body piston 6, fluid is flowed out by oil outlet 18.When pump housing piston 6 moves down, and pump housing piston 6 returns initial
Position.It is economical and practical it is therefore seen that the utility model is simple in structure, the shortcomings that significantly improving traditional plunger pump.
