Abstract
The utility model discloses a kind of diesel oil frequency plunger-type fuel pumps comprising oil inlet conduit etc., the first conduit sealing ring is between oil out duct and copper pipe, and for the second conduit sealing ring between oil inlet conduit and copper pipe, copper pipe is located at the side of shell.The problem of the utility model prevents the aging of plastic cord coil expanded with heat and contract with cold and generated, explosion to lead to product oil leak improves safety to increase service life.
Description
Technical field
The utility model relates to a kind of plunger-type fuel pumps, more particularly to a kind of diesel oil frequency plunger-type fuel pump.
Background technique
The Seal Design of plunger-type fuel pump is to be squeezed firmly by oil inlet conduit, plastic cord coil, oil out duct and formed sealing and made
With when plug is powered, product is worked normally.Generated heat leads to plastics when generating pressure and coil energization due to inside
Bobbin expands with heat and contract with cold and generates aging, explosion leads to product oil leak, brings security risk.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of diesel oil frequency plunger-type fuel pumps, fundamentally prevent
The problem of aging expanded with heat and contract with cold and generated of plastic cord coil, explosion lead to product oil leak, so that service life is increased,
Improve safety.
The utility model is to solve above-mentioned technical problem by following technical proposals: a kind of diesel oil frequency Plunger oil
Pump, which is characterized in that it includes oil inlet conduit, oil out duct, the first conduit sealing ring, copper pipe, the second conduit sealing ring, and first
Conduit sealing ring is between oil out duct and copper pipe, and the second conduit sealing ring is between oil inlet conduit and copper pipe.
The positive effect of the utility model is: the utility model fundamentally prevents the heat expansion of plastic cord coil
Shrinkage and the aging that generates, explosion the problem of leading to product oil leak to increase service life improve safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model diesel oil frequency plunger-type fuel pump.
Specific embodiment
The utility model preferred embodiment is provided, with reference to the accompanying drawing the technical solution of the utility model is described in detail.
As shown in Figure 1, the utility model diesel oil frequency plunger-type fuel pump includes oil inlet conduit 1, oil sealing 2, inlet nozzle 3, strainer
Set 4, iron core 5, shell 6, the first spring 7, coil 8, plastic cord coil 9, plunger 10, plunger bushing 11, plug 12, check valve 13,
Steel ball 14, second spring 15, oil outlet 16, oil out duct 17, the first conduit sealing ring 18, copper pipe 19, the second conduit sealing ring
20, an oil sealing 2 between oil inlet conduit 1 and inlet nozzle 3, another oil sealing 2 between oil inlet conduit 1 and filter screen set 4,
Filter screen set 4 is located in oil inlet conduit 1, and one end of oil inlet conduit 1 is connected with one end of inlet nozzle 3, the other end of oil inlet conduit 1 with
One end of shell 6 connects, and one end of filter screen set 4 is connect with one end of iron core 5, and the first spring 7 is located at iron core 5 and plunger bushing 11
Between one end, the other end of plunger bushing 11 is connect with oil outlet 16, and coil 8, plastic cord coil 9 are all located at shell 6 and plunger bushing
Between 11,11 sets of plunger bushing on plunger 10, check valve 13 is located between the other end and oil outlet 16 of plunger bushing 11, plug 12
It is connect with the other end of shell 6, steel ball 14 is located in check valve 13, and second spring 15 is between steel ball 14 and oil nozzle 16, out
17 sets of oil-piping layout connect on plunger bushing 11 and with oil outlet 16, and the first conduit sealing ring 18 is located at oil out duct 17 and copper pipe 19
Between, for the second conduit sealing ring 20 between oil inlet conduit 1 and copper pipe 19, copper pipe 19 is located at the side of shell 6.
The Seal Design of the plunger-type fuel pump, when plug is powered, is produced by oil inlet conduit, plastic cord coil, oil out duct
Product work normally, and when iron core is axially moved, oil is fuel-displaced from oil outlet from inlet nozzle oil inlet.Oil inlet conduit, plastic cord coil and
Increase copper pipe, the first conduit sealing ring, the second conduit sealing ring between oil out duct, in this way increase leakproofness.The utility model
Sealing structure be made of conduit sealing ring, copper pipe, oil inlet conduit, oil out duct etc., the design by the sealing structure it is complete
Plastic cord coil has been isolated, the aging of plastic cord coil expanded with heat and contract with cold and generated, explosion is fundamentally prevented to lead to product
The problem of oil leak, improves safety to increase service life.
Particular embodiments described above, the technical issues of to the solution of the utility model, technical scheme and beneficial effects
It has been further described, it should be understood that the foregoing is merely specific embodiment of the utility model, not
For limiting the utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
