Description
Technical field
Oily collection device is penetrated based on comings PT fuel injector test experiences the present invention relates to a kind of.
Background technology
Important component in fuel injector engine, PT fuel injectors are usually used in large-scale engineering machinery engine, such as ore deposit
Mountain machinery is medium, and since working environment is severe, engine fuel injector long time continuous working, the accurate coupling part in fuel injector may
It can wear, have a certain impact to its normal use, therefore fuel injector must be detected in use for some time.At present,
There is no penetrate oily collection device with what the detection of fuel injector emitted dose matched.
Invention content
Present invention seek to address that the problem of be to provide it is a kind of based on comings PT fuel injector test experiences penetrate oil collect dress
It puts, to realize detection fuel injector injection amount of fuel, reduce when detecting to the purpose of fuel injector damage.
For the above situation, technical solution provided by the invention is
It is a kind of that oily collection device is penetrated based on comings PT fuel injector test experiences, it is sealed including anchor tip, fuel injector
Part, connector, oil pipe, hydraulic cylinder, collector,
One end of the anchor tip is connected through a screw thread on the piston rod for being fixed on the hydraulic cylinder, the anchor tip
The other end it is axially disposed have a ladder counterbore, injector seal is tightly embedded intp by interference fit and is fixed on anchor tip
Ladder counterbore in, anchor tip and injector seal prevent injection oil from being flowed out from its fitting surface using interference fit, and work as
It from anchor tip can be knocked out after sealing part abrasion, replace injector seal.It is set in the injector seal
Interconnected axial blind hole and radial blind holes are equipped with, the outlet of the axial blind hole is provided with seals the close of cooperation with fuel injector
The conical surface is sealed, outlet and the radial through-hole on anchor tip side wall of the radial blind holes are connected to each other, and one end of the oil pipe passes through
Connector connects radial through-hole, and the other end is stretched into collector.
Further, the injector seal uses nylon material, to fuel injector when nylon material not only reduces test
The damage of the conical surface, and nylon can generate certain compressive deformation during hydraulic cylinder axial force compression, so as to improve fuel injector sealing
The sealing effect of part and fuel injector.
Further, the injector seal outer wall is axially disposed flat key shape positioning protrusion, the anchor tip
Ladder counterbore inner wall it is axially disposed have a positioning groove to match with the positioning protrusion, this programme is determined by similar flat key
The mode of position ensures the centering of anchor tip and injector seal oil outlet.
Further, the anchor tip material uses hard alloy, ensures the bonding strength of anchor tip and piston rod.
Further, the connector is quick disconnecting joint, is easily installed, facilitates detection.
Damage when can effectively reduce detection using above-mentioned design to fuel injector, the application of nylon material can enhance the conical surface and match
The leakproofness of conjunction, split-type design can reduce the replacement cost after part injury.Therefore the present apparatus has simple in structure, installing and dismounting
The advantages that facilitating can effectively improve the detection efficiency of fuel injector, injury when reducing detection to fuel injector.

Specific embodiment
The purpose of the present invention is described in further detail below by specific embodiment, embodiment cannot herein one by one
It repeats, but therefore embodiments of the present invention are not defined in following embodiment.
As shown in Figure 1 to Figure 3, it is a kind of that oily collection device is penetrated based on comings PT fuel injector test experiences, including fixation
Connector 1, injector seal 2, connector 3, oil pipe 4, fuel injector 5, hydraulic cylinder 6, collector 7,
One end of the anchor tip 1 is connected through a screw thread on the piston rod for being fixed on the hydraulic cylinder 6, and the fixation connects
First 1 other end is axially disposed ladder counterbore, and 1 material of anchor tip uses hard alloy, ensure anchor tip with
The bonding strength of piston rod.
Injector seal 2 is tightly embedded intp by interference fit in the ladder counterbore for being fixed on anchor tip 1, and fixation connects
First 1 and injector seal 2 using interference fit, prevent injection oil from being flowed out from its fitting surface, and can be by after sealing element 2 is worn
It is knocked out from anchor tip 1, replaces injector seal 2.It is provided in the injector seal 2 interconnected
Axial blind hole and radial blind holes, the outlet of the axial blind hole are provided with the sealing cone with the sealing cooperation of fuel injector 5, the diameter
It being connected to each other to the outlet of blind hole and the radial through-hole on 1 side wall of anchor tip, the injector seal 2 uses nylon material,
Damage when nylon material not only reduces test to the fuel injector conical surface, and nylon can generate centainly during hydraulic cylinder axial force compression
Compressive deformation, so as to improve the sealing effect of injector seal 2 and fuel injector.
One end of the oil pipe 4 connects radial through-hole by connector 3, and the other end is stretched into collector 7, and the connector 3 is
Quick disconnecting joint.
2 outer wall of injector seal is axially disposed flat key shape positioning protrusion, and the ladder of the anchor tip 1 sinks
Hole inner wall is axially disposed the positioning groove to match with the positioning protrusion, when pinning again in this way, is determined by similar flat key
The mode of position ensures the centering of 2 oil outlet of anchor tip 1 and injector seal.
During detection, axial force that fuel injector 5 is provided by hydraulic cylinder 6 closely connects with the sealing cone of injector seal 2
