Abstract
The utility model belongs to aero fuel pump field, designs a kind of split type fuel oil pump packing structure, including shell 1, strainer 2 and sealing ring 3；Shell 1 includes mounting flange 4, oil inlet 5, and split type fuel pump is mounted on fuel tank internal, is fixed on oil tank wall by mounting flange 4, and the fuel oil in fuel tank is flowed into pump by oil inlet 5；Strainer 2 includes mesh 6, sealing ring 7 and seal groove 8, and seal groove 8 is located at 2 periphery of strainer, is distributed in the left and right sides of mesh 6 and the left and right sides of sealing ring 7；Sealing ring 3 is installed in the seal groove 8 of strainer 2.Sealing ring and strainer Integration Design are integrated by the utility model using sealing loop type, when for pump core dismounting, sealing oil inlet reduces the spare part quantity of fuel pump to prevent fuel oil from entering in pump, the weight for alleviating fuel pump improves the reliability of fuel pump.
Description
Technical field
The invention belongs to aero fuel pump fields, design a kind of split type fuel oil pump packing structure.
Background technique
Aero fuel pump is the core component of Aviation Fuel system, and split type fuel pump is important one kind of aero fuel pump
Structure type has the characteristics that high reliablity, dismounting are easy to maintain.
When split type fuel pump dismounting pump core, there need to be self-sealing function, generally be realized frequently with sealing active door, structure is multiple
Miscellaneous, spare part is more, reduces fuel pump reliability, increases fuel pump weight.
Summary of the invention
The purpose of the present invention: a kind of split type fuel oil pump packing structure is designed.
Technical solution of the present invention:
A kind of split type fuel oil pump packing structure, including shell 1, strainer 2 and sealing ring 3；
Shell 1 includes mounting flange 4, oil inlet 5, and split type fuel pump is mounted on fuel tank internal, solid by mounting flange 4
It is scheduled on oil tank wall, the fuel oil in fuel tank is flowed into pump by oil inlet 5；
Strainer 2 includes mesh 6, sealing ring 7 and seal groove 8, and seal groove 8 is located at 2 periphery of strainer, is distributed in mesh
6 left and right sides and the left and right sides of sealing ring 7；Sealing ring 3 is installed in the seal groove 8 of strainer 2.
Seal groove 8 has 4；Or seal groove 8 has 3,6 left side of mesh is sealed with shared one on the right side of sealing ring 7
Ring recess 8.
When being packed into pump core in split type fuel pump pump case, mesh 6 is aligned with the oil inlet 5 on shell 1, liquid level of fuel oil in fuel tank by
Oil inlet 5 flows into and enters in pump through mesh 6；
When the pump core of split type fuel pump is removed, sealing ring 7 is aligned with oil inlet 5, and liquid level of fuel oil in fuel tank is flowed by oil inlet 5
Afterwards, stopped by sealing ring 7, fuel oil cannot be introduced into pump.
Beneficial effects of the present invention:
A kind of split type fuel oil pump packing structure that the present invention designs, using strainer and sealing ring integrated design method,
The sealing ring being used at oil inlet and strainer are designed as a part, structure is simple, reliable, fuel pump reliability is improved,
Reduce fuel pump weight.
Detailed description of the invention:
Fig. 1 is structural schematic diagram when split type fuel oil pump packing structure of the invention is opened；
Fig. 2 is structural schematic diagram when split type fuel oil pump packing structure of the invention is closed；
Wherein, 1- shell, 2- strainer, 3- sealing ring, 4- mounting flange, 5- oil inlet, 6- mesh, 7- sealing ring, 8- are close
Seal slot.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail.
As shown in Figure 1 to Figure 2, a kind of split type fuel oil pump packing structure, including shell 1, strainer 2 and sealing ring 3；Shell
1 includes mounting flange 4, oil inlet 5, and split type fuel pump is mounted on fuel tank internal, is fixed on oil tank wall by mounting flange 4
On, the fuel oil in fuel tank is flowed into pump by oil inlet 5；Strainer 2 includes mesh 6, sealing ring 7 and seal groove 8, seal groove
8 are located at 2 periphery of strainer, are distributed in the left and right sides of mesh 6 and the left and right sides of sealing ring 7；In split type fuel pump pump case
When being packed into pump core, mesh 6 is aligned with the oil inlet 5 on shell 1, and liquid level of fuel oil in fuel tank is flowed by oil inlet 5 and entered through mesh 6 and pumps
It is interior；When the pump core of split type fuel pump is removed, sealing ring 7 is aligned with oil inlet 5, after liquid level of fuel oil in fuel tank is flowed by oil inlet 5, quilt
Sealing ring 7 stops, and fuel oil cannot be introduced into pump.
Sealing ring 3 is installed in the seal groove 8 of strainer 2.Seal groove 8 has 4；Or seal groove 8 has 3, net
6 left side of hole and a seal groove 8 shared on the right side of sealing ring 7.When being packed into pump core in split type fuel pump pump case, sealing ring 3
It seals between shell 1 and strainer 2, prevents from pumping outside the gap efflux pump that interior fuel oil passes through between shell 1 and strainer 2；
When split type fuel pump removes pump core, sealing ring 3 seals between shell 1 and strainer 2, prevents fuel oil from passing through shell
Gap between 1 and strainer 2 flows into pump.The opening and closing of sealing structure are carried out by the way of pull.
