Description
Technical field
It the utility model is related to pump housing technical field, and in particular to a kind of miniature lobe pump.
Background technology
Water pump is the machinery for conveying liquid or being pressurized liquid.It transmits the mechanical energy of prime mover or other external energies
Liquid, increase liquid energy, being mainly used to conveying liquid includes water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid gold
Category etc., can also convey liquid, admixture of gas and the liquid containing suspended solids.The technical parameter for weighing pump performance has stream
Amount, suction, lift, shaft power, water-horse power, efficiency etc..Flow refers to the amount of liquid exported in the unit interval by pump discharge；Raise
Journey is energy increment of the Unit Weight conveying liquid from pump intake to outlet.The efficiency of water pump is not an independent performance parameter,
It can be calculated by formula by other performance parameter such as flow, lift and shaft power and tried to achieve.Conversely, known mass flow, lift and
Efficiency, it can also obtain shaft power.The power source of electric water pump is motor.
Micropump is the liquid conveying water pump for providing low dose in narrow space for special-purpose, but existing
Micropump is complicated, and use condition is high, price, is not suitable for the simple mechanism requirement of some low dose of liquid conveyings.
Utility model content
The utility model is in order to solve the above technical problems, it is that special-purpose provides small dose in narrow space to provide a kind of
The miniature lobe pump of liquid conveying of amount.
Technical problem to be solved in the utility model is realized using following technical scheme.
A kind of miniature lobe pump, including pump body top cover, pump housing lower cover, U-tube, tooth case lid, cam, gear train, drive horse
Reach；The drive motor is arranged in the pump housing lower cover, drive motor rotating shaft front end installation drive gear, the drive gear
Ratcheting with gear train, cam is ratcheting by first gear and the gear train, and drive motor rotation driven gear group rotates, gear
Group, which rotates, to be driven first gear to rotate and then causes cam rotation, and cam upper end passes through tooth case lid, and described U-tube one end is charging
Mouthful, the other end is discharging opening, and cam upper end forms squeezed state with U-shaped hose bending section, and pump body top cover is fastened on pump housing lower cover
Upper formation enclosed construction.
It is further preferred that the gear train includes gear, the lower gear being set up in parallel up and down, the gear and institute
It is ratcheting to state first gear, the lower gear and the drive gear are ratcheting.
It is further preferred that the cam is triangular cam.
The beneficial effects of the utility model are：The lobe pump is simple in construction, and volume is small, with a triangular cam to U
Unidirectional extruding of type pipe, realize that the cavity of pump separates and liquid transmission；U-shaped flexible pipe had both been liquid conducting pipes, was pump again
A part for chamber, is combined into one, and completely without leakage problem and associated contamination problem, need not consider the close of driving gear set completely
Envelope problem.

Wheel 8, drive gear 8 and gear train 5 are ratcheting, and cam 4 is ratcheting by first gear 10 and gear train 5, and gear train 5 is included up and down simultaneously
The gear 6 set, lower gear 7 are arranged, gear 6 and first gear 10 are ratcheting, and lower gear 7 and drive gear 8 are ratcheting, drive horse
Rotated up to 9 rotation driven gear groups 5, the rotation drive first gear 10 of gear train 5 rotates and then so that cam 4 rotates, cam 4 is excellent
Elect triangular cam as, the upper end of cam 4 passes through tooth case lid 3, and U-shaped one end of flexible pipe 2 is charging aperture, and the other end is discharging opening, on cam 4
End forms squeezed state with the U-shaped bending section of flexible pipe 2, and pump body top cover 1 is fastened on pump housing lower cover 11 and forms enclosed construction.
Using the deformation of U-shaped flexible pipe 2, extrude, U-shaped flexible pipe 2 is separated into successively several small by the cam 4 of single direction rotation
Space, and operated by Fig. 3 to Fig. 6 order, when running to Fig. 3, charging aperture I sections and A sections are UNICOMs, full of medium, to Fig. 4
Position, A sections enclose certain media, and during to Fig. 5 positions, medium is all enclosed in A sections and B sections, during to Fig. 6 positions, B sections and II
Duan Xiangtong, medium are transported to discharging opening, so moved in circles, and medium is continuously transferred out.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
