Description
Technical field
The invention belongs to mechanical detection equipment, relates generally to electrically-controlled pump nozzle detection oil spout oil catcher.
Background technology
At present, as the upgrading of China's diesel engine emissions regulations is perfect, domestic diesel engine uses electronic control injection technology one after another
To meet requirement.Wherein electrically-controlled pump nozzle system is exactly a kind of important technology path.Electrically-controlled pump nozzle, in test, is collection
Its distributive value size is, it is necessary to an oil collector sump tank, the diesel oil that electrically-controlled pump nozzle sprays is collected into test container and is measured.
At present, the oil collector sump tank for using at home uses screws tighten, and does not set fluid stopping mechanism.In actual job, not only operate
Complicated, cumbersome, sealing effectiveness is poor, especially detection terminate dismounting oil catcher when, wherein the diesel oil for remaining flow on testing stand into
It is waste oil, causes greatly waste, and pollution environment.
The content of the invention
The problem that the purpose of the invention exists aiming at above-mentioned prior art, a kind of electricity of new construction of R ＆ D design
Control Unit injector oil spout oil catcher, reaches and uses easy and convenient operation, raising detection operation efficiency, reduction diesel oil to lose unrestrained
Take, the purpose that oil-saving effect is good.
What the purpose of the invention was realized in：Oil transportation hole is opened up on device casing center position, in the device shell
Body upper center hole portion position is upper, be interconnected successively from bottom to up positioned at oil transportation hole top and it is concentric with loaded check valve, it is multiple
Position compression spring and oil transfer joint, the oil transfer joint sealing are fixedly mounted on device housing, the upper and lower end of reset compression spring
Face is engaged with oil transfer joint and check-valves respectively, and the check-valves is in contact to close what is coordinated or disengage with oil transportation hole
Open and coordinate, end-face seal ring and face of cylinder sealing ring, valve are installed successively from top to bottom in centre bore on the downside of the device housing
Formula collet is installed on device housing bottom, be connected through a screw thread on outside on the downside of the device housing cooperation and can be upper and lower
The installation locking nut of mobile regulation, the lock nut is located at flap-type collet outside portion in being engaged, and so far constitutes
Electrically-controlled pump nozzle oil spout oil catcher.
The invention structure is novel, reasonable, simple, and when testing electrically-controlled pump nozzle, clamping is convenient and swift, and
Good airproof performance, when being completed the dismounting electrically-controlled pump nozzle from oil catcher, the diesel oil remained in oil catcher will not flow out, it is to avoid bavin
The loss and waste of oil, and it is free from environmental pollution.The invention is applied widely, and can coordinate with the electrically-controlled pump nozzle of different model makes
With.
Brief description of the drawings
Fig. 1 is electrically-controlled pump nozzle oil spout oil catcher general structure schematic diagram.
Piece number explanation in figure：
1st, oil transfer joint, 2, reset compression spring, 3, check-valves, 4, device housing, 5, end-face seal ring, 6, face of cylinder sealing
Circle, 7, lock nut, 8, flap-type collet, 9, oil transportation hole.
Specific embodiment
The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of electrically-controlled pump nozzle oil spout oil-collecting
Device, oil transportation hole 9 is opened up on the centre of device housing 4, on the upper center hole portion of the device housing 4 position, on oil transportation hole 9
Side is interconnected and concentric with loaded check valve 3, reset compression spring 2 and oil transfer joint 1, the oil transportation successively from bottom to up
The sealing of joint 1 is fixedly mounted on device housing 4, the upper and lower end face of reset compression spring 2 respectively with oil transfer joint 1 and check-valves 3
It is engaged, the check-valves 3 is in contact the opening cooperation that closing coordinates or disengages with oil transportation hole 9, in the device housing 4
End-face seal ring 5 and face of cylinder sealing ring 6 are installed successively from top to bottom, flap-type collet 8 is installed in device in the centre bore of downside
On the bottom of housing 4, the installation lock that coordinate and can move up and down regulation is connected through a screw thread on the downside outside of the device housing 4
Tight nut 7, it is in be engaged that the lock nut 7 is located at the outside portion of flap-type collet 8.
During test electrically-controlled pump nozzle, using flap-type collet, 8 sets are buckled on the oil nozzle pressure cap of tested electrically-controlled pump nozzle, will
This oil spout oil catcher is integrally provided on electrically-controlled pump nozzle, pushes this oil spout oil catcher, makes the oil nozzle pressure cap point of electrically-controlled pump nozzle
It is not adjacent to end-face seal ring 5, face of cylinder sealing ring 6 and is coordinated in sealing, flap-type collet 8 is made by rotation lock nut 7
Shrink, oil spout oil catcher is fastened together with tested electrically-controlled pump nozzle, test bed testing oil collecting pipe is connected with oil transfer joint 1
Connect.High-pressure diesel in tested electrically-controlled pump nozzle enters in oil transportation hole 9, and compress reset compression spring 2 make check-valves 3 depart from
The cooperation in sealing contact in oil transportation hole 9, diesel oil completes test from the feeding testing stand of oil transfer joint 1.Quilt is dismantled from oil spout oil catcher
When surveying electrically-controlled pump nozzle, pressure diesel oil stops conveying, and reset compression spring 2 sends check-valves 3 back to initial position, by oil transportation hole 9
Closing, it is to avoid the leakage of residual diesel oil in device housing 4.
