Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1, the utility model provides a kind of gear pump, comprising:
The pump housing 8, it is fixed with pump cover 7;
Live axle 3, its mounting hole being installed on the described pump housing 8 and described pump cover 7 is placed on bearing 2, described live axle 3 is provided with fuel oil oil sealing 5 and machine oil oil sealing 6, described fuel oil oil sealing 5 is (as Fig. 2 a, Fig. 2 b, shown in Fig. 3 and Fig. 4) adopt single lip mouth skeleton oil seal, described fuel oil oil sealing 5 material is fluorine rubber, described machine oil oil sealing 6 is (as Fig. 5 a, Fig. 5 b, shown in Fig. 6 and Fig. 7) adopt dual-lip framework oil seal, described machine oil oil sealing 6 material is ethylene, propylene, indicator hole 9 is offered between described fuel oil oil sealing 5 and described machine oil oil sealing 6, described indicator hole 9 opening is provided with screw thread,
Driving gear 4, it is fixed on described live axle 3, and described driving gear 4 is also engaged with driven gear 1;
Engine oil level sensor 10, it is threadedly connected to the opening of described indicator hole 9, described engine oil level sensor 10 by connection to analysis meter, after there is oil in the required described indicator hole 9 of described engine oil level sensor sense 10, signal is shown on described analysis meter through conversion treatment.
The gear pump that the utility model provides, fuel oil oil sealing 5 and machine oil oil sealing 6 are housed between gear pump oil pumping chamber and live axle 3, distributed pins is to the diesel oil of 5-15bar pressure and lubricant oil, when fuel oil oil sealing 5 lost efficacy, because organic oil oil sealing 6 seals, can prevent fuel oil from flowing in engine lubrication system, by the double sealing structure of fuel oil oil sealing 5 and machine oil oil sealing 6, substantially increase the sealing reliability of gear pump; By setting up indicator hole 9, engine oil level sensor 10, achieve and gear pump working state is monitored in real time, when oil sealing all lost efficacy, oil is there is in indicator hole 9, be presented at after the signal that engine oil level sensor 10 sends processes by analysis on analysis meter, the beacon of analysis meter lights, prompting changing gear pump, in case gear pump lost efficacy cause whole engine damage, avoided causing a serious accident; The oil outlet place of described gear pump is also provided with safety check, and it keeps fuel oil not to be lowered by fuel tank, reduces engine start time, improves the starter motor life-span.
Although embodiment of the present utility model is open as above, but it is not limited in listed in specification and mode of execution utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
