Abstract
The utility model discloses a novel fuel pump for an aeroderivative gas turbine. The fuel pump is a gear type fuel pump which comprises a driving gear, a driven gear, a driving shaft, a driven shaft, a pump body, a front cover, a rear cover, an oil inlet and an oil outlet, wherein shaft sleeves are also arranged among the driving gear, the driven gear and an inner hole of the pump body; inner closing rings are respectively arranged between the front cover and the shaft sleeves as well as between the rear cover and the shaft sleeves; outer closing rings are respectively arranged between the front cover and the pump body as well as between the rear cover and the pump body. The novel fuel pump is simple in structure, long in service life, high in working reliability and low in cost. By the adoption of the novel fuel pump, more than 200,000 RMB can be saved for each fuel pump, the 8,000-hour service life of the fuel pump is much longer than the 500-hour service life of a plunger pump; the reliability of the gear pump with a simple structure is also much higher than that of the plunger pump with a complicated structure.
Description
Technical field
The utility model belongs to gas turbine engineering field, provides especially one to can be used for boat and changes combustion machine novel fuel pump.
Background technique
The airborne fuel pump of the general configuration of domestic fuel combustion type gas turbine standby power supply unit, to reduce power load in startup of unit process.At present Fuel On Board pump adopts plunger-type structure fuel pump more, and plunger type fuel pump complex structure, working life is short, functional reliability is poor, cost is high.
Model utility content
The purpose of this utility model be to provide one can be used for boat change combustion machine novel fuel pump, can effectively address the above problem.
The technical solution of the utility model is: one can be used for boat and changes combustion machine novel fuel pump, and described fuel pump is gear type fuel pump.
Preferably, described gear type fuel pump comprises: driving gear 1, driven gear 2, driving shaft 3, driven shaft 4, the pump housing 5, protecgulum 6, bonnet 7, filler opening 8 and oil outlet 9; Described filler opening 8 and oil outlet 9 are located on the pump housing 5, the described pump housing 5 is connected to form an enclosed cavity with protecgulum 6 and bonnet 7 respectively, described driving gear 1, driven gear 2, driving shaft 3, driven shaft 4 are located in cavity, described driving gear 1 and driven gear 2 are set on driving shaft 3 and driven shaft 4, described driving gear 1 and driven gear 2 engage, and between described driving gear 1, driven gear 2 and the pump housing 5 endoporus, are also provided with axle sleeve 10.
Preferably, between described protecgulum 6 and bonnet 7 and axle sleeve 8, be respectively equipped with inner sealing circle 11, between described protecgulum 6 and bonnet 7 and the pump housing 5, be respectively equipped with outer closure circle 12.
The utlity model has following useful effect:
The utility model is simple in structure, long service life, functional reliability is strong, cost is low.Adopt before this novel fuel pump, the fuel pump that gas turbine adopts is the aeroengine fuel pump transformation of the way, is plunger-type structure, and long, complex structure of this pump manufacture cycle, cost is high, the life-span is short, is unfavorable for the marketization of gas turbine.Adopt after this novel fuel pump, every fuel pump can be saved more than 20 ten thousand yuan, and the life-span can reach 8000 hours, a lot of more than 500 little durations of plunger pump, and the reliability of gear pump simple in structure is also high a lot of than baroque plunger pump.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is gear pump fundamental diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As Figure 1-3, one can be used for boat and changes combustion machine novel fuel pump, is gear type fuel pump.Comprise: driving gear 1, driven gear 2, driving shaft 3, driven shaft 4, the pump housing 5, protecgulum 6, bonnet 7, filler opening 8 and oil outlet 9; Filler opening 8 and oil outlet 9 are located on the pump housing 5, the pump housing 5 is connected to form an enclosed cavity with protecgulum 6 and bonnet 7 respectively, driving gear 1, driven gear 2, driving shaft 3, driven shaft 4 are located in cavity, driving gear 1 and driven gear 2 are set on driving shaft 3 and driven shaft 4, driving gear 1 and driven gear 2 engage, and between driving gear 1, driven gear 2 and the pump housing 5 endoporus, are also provided with axle sleeve 10.Between protecgulum 6 and bonnet 7 and axle sleeve 8, be respectively equipped with inner sealing circle 11, between protecgulum 6 and bonnet 7 and the pump housing 5, be respectively equipped with outer closure circle 12.
Driving gear 1 and driven gear 2 are intermeshing, be inclusive in the enclosed cavity that the pump housing 5, protecgulum 6 and bonnet 7 form, the tooth top of driving gear 1 and driven gear 2 and the pump housing 5 bore area gaps are very little, the gear face of driving gear 1 and driven gear 2 and protecgulum 6, bonnet 7 gaps are also very little, thereby have formed two oil closed cavities that separate by driving gear 1 and driven gear 2 contact pointss along the Line of contact of gear direction.In the time that input driving shaft 3 clockwise rotates according to direction as shown edge, the enclosed volume in contact points left side becomes large, causes parital vacuum, and the oil of fuel tank enters under atmospheric action, forms oil sucting cavity.Opposite side, the volume of sealing diminishes gradually, and oil pressure is gone out, and forms pumping cavity, oil suction and the force feed process of Here it is gear pump.When driving shaft 3 rotates continuously, the spatial volume of oil sucting cavity and pumping cavity continuously changes, and has just formed continuously oil suction and force feed.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
