Fig. 2 is fundamental diagram of the present invention.
In figure: 1, pump case; 2, driving gear; 3, driven gear; 4, oil sucting cavity; 5, oil-discharging cavity; 6, filler opening; 7, oil outlet; 8, driving shaft; 9, driven axle; 10, coupling; 11, drive unit; 12, filter medium.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, a kind of gear oil pump with filtrating equipment shown in Fig. 2, there is pump case 1, driving gear 2 and driven gear 3 is provided with in described pump case 1, driving gear 2 and driven gear 3 mutually activity are connected with a joggle, diameter after driving gear 2 engages with driven gear 3 equals the height in pump case 1 inner chamber Vertical direction, pump case 1 inner chamber is divided into oil sucting cavity 4 and oil-discharging cavity 5 by the driving gear 2 after engagement and driven gear 3, pump case 1 side be connected with oil sucting cavity 4 is provided with filler opening 6, filler opening 6 and oil sucting cavity 4 UNICOM, pump case 1 side be connected with oil-discharging cavity 5 is provided with oil outlet 7, oil outlet 7 and oil-discharging cavity 5 UNICOM, the centre of driving gear 2 and driven gear 3 is arranged with driving shaft 8 and driven axle 9 respectively, driving shaft 8 is connected with coupling 10 through pump case 1, driving shaft 8 is by coupling 10 connecting drive device 11, drive unit 11 connects power supply (not shown), described filler opening 6 is provided with filter medium 12, filter medium 12 moving card is located on filler opening 6, described filter medium 12 is bag type filter device, filter medium 12 is provided with differential pressure controller (not shown), differential pressure controller connects warning device (not shown), structure of the present invention is simple, volume is little, lightweight, stable performance when in use, safety coefficient is higher, maintenance expense is cheap, simultaneously owing to being provided with filter medium 12 at filler opening 6 place, granule foreign in fluid first can be filtered out, granule foreign is not caused to enter in gear oil pump, wearing and tearing or stuck damage gear oil pump, can also by the pressure in differential pressure controller and warning device monitoring filter medium, to reach monitoring filter medium the need of replacing cleaning.
When gear oil pump work time, fluid flows into filler opening 6 by oil transport pipeline, and filtered by the filter medium 12 be fastened on filler opening 6, solid particle polluter is trapped in filter medium 12 by filter medium 12, fluid after filtration flows in pump case 1, simultaneously, drive unit 11 drives driving gear 2 to rotate, driving gear 2 drives the driven gear 3 be engaged with to rotate, the engaging tooth of driving gear 2 and driven gear 3 is when oil sucting cavity is separated gradually, the gear teeth of driving gear 2 exit from the between cog of the gear of driven gear 3, between cog is made to form vacuum, oil is taken to oil-discharging cavity 5 from oil sucting cavity 4, gear constantly rotates, oil in the between cog that the gear teeth engage one by one is just successively forced out, oil pressure is formed under the effect of external load, along with the continuous rotation of gear, oil pump is constantly oil suction and oil extraction just, when the resistance (pressure) in oil circuit exceedes safety pressure, safety valve just starts, the oil of oil-discharging cavity is made to get back to oil sucting cavity, thus reduction pressure, safety protection effect is play to pump and pipeline.
When the impurity blocking filtering hole retained in filter medium 12 is that the pressure in filter medium 12 raises, the warning device connecting differential pressure controller is reported to the police, and warning staff filter medium 12 needs to change or cleaning.While the safety coefficient improving gear oil pump use, Automated condtrol can also be reached.
