Embodiment
One kind being based on the corrosion-resistant metering pump of gear-driven high-precision, for that need to draw corrosive liquids from Pressure Vessel
Medium simultaneously quantitatively with pressure is discharged in designated equipment or system.Metering pump is mainly by bottom plate 4, middle plate 2, top plate 1, active
Axis 6, driven shaft 5, driving gear 8, driven gear 3 and axial sealer 9 form, wherein driving gear 8 and driven gear 3
It is two involute spur gears with identical parameters.The axial sealer includes mounting base, lantern ring for liquid seal, pressure
Fixed, locking nut and packing seal element.
As shown in Figure 1,2 connecting bottom board 4 of middle plate, 1 connecting middle plate 2 of top plate is fastened by screw between three
Connection.8 inner hole of driving gear and driving shaft 6 cooperate, by 7 drive motion of round key, between the two without relative motion, driving shaft 6
With 4 clearance fit of bottom plate.3 inner hole of driven gear and driven shaft 5 cooperate, and driven shaft 5 is connect with 4 interference of bottom plate, driven tooth
Wheel 3 rotates on driven shaft 5.The axial sealer 9 connects top plate 1, is fastenedly connected between the two by screw,
Driving shaft 6 passes through axial sealer 9 through top plate 1.
As shown in Fig. 2, the mounting base 10 connects top plate 1, it is fastenedly connected between the two by screw.First packing seal
Part 11, lantern ring for liquid seal 12, the second packing seal element 13 and clamping sleeve 14 are placed in mounting base 10, are locked by locking nut 15
Tightly.By the coupling mechanism force of adjusting lock nut 15, the decrement of adjustable packing seal element.Flat key 16 and external motor connect
It connects, the transmitting for torque and movement.Axial sealer for realizing the sealing between driving shaft and top plate, sealing mainly according to
Packing seal element close to the inner portion.
Metering pump driving shaft 6, driving gear 8, driven shaft 5 and driven gear 3 to be coated with one layer of amorphous carbon thin for outer surface
Film, the coating process can greatly improve the hardness of part, increase its wearability, and have certain self-lubricating property, are applicable in
In the occasion of dry friction.Experiment proves that the metering pump component after plated film has the characteristics that long service life, stability are good.
The metering pump is to drive a pair of identical gear, i.e. driving gear 8 and driven gear 3 through driving shaft by motor,
It is closed in the cavity being made of bottom plate, middle plate and top plate and engages operating, using the cyclically-varying of inter-tooth volume come real
Existing oil suction and pressure oil.Driving gear 8 and driven gear 3 intermesh, very due to the tooth top of gear and 2 bore area gap of middle plate
It is small, gear face and cover board (bottom plate 4 and top plate 1) gap very little, thus oil sucting cavity and pumping cavity are separated.When driving gear 8
When rotating through motor driven, the tooth that oil sucting cavity side engages is gradually backed out engagement, and space increases, formation parital vacuum, in fuel tank
Oil external atmosphere pressure effect under enter oil sucting cavity；The tooth of pumping cavity side progresses into engagement, and the oil liquid of between cog is squeezed out
Come, is forced through from press oil port.Here it is the oil suctions of metering pump and pressure oil process.When driving gear 8 constantly rotates, gear pump
Just constantly oil suction and pressure oil.
