Description
Technical field
The invention belongs to mechanical detection equipment, relates generally to electrically-controlled pump nozzle detection oil spout oil catcher.
Background technique
Currently, domestic diesel engine uses electronic control injection technology one after another as the upgrading of China's diesel engine emissions regulations is perfect
To meet the requirements.Wherein electrically-controlled pump nozzle system is exactly a kind of important technology path.Electrically-controlled pump nozzle is in test, for acquisition
Its distributive value size needs an oil collector sump tank, and the diesel oil that electrically-controlled pump nozzle sprays is collected into test container and is measured.
Currently, the oil collector sump tank used at home is all made of screws tighten, and fluid stopping mechanism is not set.In actual job, not only operate
It is complicated, cumbersome, poor sealing effect, especially detection terminate disassembly oil catcher when, wherein remaining diesel oil flow on testing stand at
It for waste oil, causes greatly to waste, and pollutes environment.
Summary of the invention
The purpose of the invention is aiming at the above-mentioned problems of the 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 operating efficiency, reduction diesel oil loss unrestrained
Take, the purpose that oil-saving effect is good.
The purpose of the invention, which is achieved in that, opens up oil transportation hole on device casing center position, in the device shell
Successively be interconnected from bottom to up on the position of body upper center hole, above oil transportation hole 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 shell, reset the upper and lower end of compression spring
Face is engaged with oil transfer joint and check-valves respectively, and the check-valves is in contact closing cooperation or disengage with oil transportation hole
Cooperation is opened, end-face seal ring and cylindrical surface sealing ring, valve are successively installed in centre bore from top to bottom on the downside of the device shell
Formula elastic collet is installed in device housing bottom portion, is connected through a screw thread cooperation on outside on the downside of the device shell and can be upper and lower
The mobile installation locking nut adjusted, the lock nut are located at flap-type elastic collet outside portion in being engaged, so far constitute
Electrically-controlled pump nozzle oil spout oil catcher.
The invention structure novel, rationally, it is simple, it is easy to install when testing electrically-controlled pump nozzle, and
Good airproof performance, when being completed the disassembly electrically-controlled pump nozzle from oil catcher, remaining diesel oil be will not flow out in oil catcher, avoid bavin
The loss and waste of oil, and it is free from environmental pollution.The invention is applied widely, and can cooperate with the electrically-controlled pump nozzle of different model makes
With.
Detailed description of the invention
Fig. 1 is electrically-controlled pump nozzle oil spout oil catcher general structure schematic diagram.
Piece number illustrates in figure:
1, oil transfer joint, 2, reset compression spring, 3, check-valves, 4, device shell, 5, end-face seal ring, 6, cylindrical surface sealing
Circle, 7, lock nut, 8, flap-type elastic collet, 9, oil transportation hole.
Specific embodiment
The invention embodiment is described in detail with reference to the accompanying drawing.A kind of electrically-controlled pump nozzle oil spout oil-collecting
Device opens up oil transportation hole 9 on 4 centre of device shell, on the 4 upper center hole position of device shell, is located on oil transportation hole 9
Side be successively interconnected from bottom to up and it is concentric with loaded check valve 3, reset compression spring 2 and oil transfer joint 1, the oil transportation
Connector 1 sealing be fixedly mounted on device shell 4, reset compression spring 2 upper and lower end face respectively with oil transfer joint 1 and check-valves 3
It is engaged, the check-valves 3 is in that the opening for contacting closing cooperation or disengaging cooperates with oil transportation hole 9, in the device shell 4
End-face seal ring 5 successively is installed from top to bottom in the centre bore of downside and cylindrical surface sealing ring 6, flap-type elastic collet 8 are installed in device
On 4 bottom end of shell, it is connected through a screw thread cooperation on the 4 downside outside of device shell and the installation lock of adjusting can be moved up and down
Tight nut 7, it is in be engaged that the lock nut 7, which is located at 8 outside portion of flap-type elastic collet,.
When testing electrically-controlled pump nozzle, it is buckled on the oil nozzle pressure cap of tested electrically-controlled pump nozzle using 8 sets of flap-type elastic collet, it 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, cylindrical surface sealing ring 6 in sealing cooperation, flap-type elastic collet 8 is made by rotation lock nut 7
It shrinks, oil spout oil catcher and tested electrically-controlled pump nozzle is fastened together, test bed testing oil collecting pipe and oil transfer joint 1 are connected
It connects.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 be detached from
The cooperation in sealing contact in oil transportation hole 9, diesel oil are sent into testing stand from oil transfer joint 1 and complete test.Quilt is dismantled from oil spout oil catcher
When surveying electrically-controlled pump nozzle, pressure diesel oil stops conveying, resets compression spring 2 for check-valves 3 and sends initial position back to, by oil transportation hole 9
Closing avoids the leakage of residual diesel oil in device shell 4.
