Abstract
The utility model discloses a fog-dissipating fuel collector used for fuel injector experiments of a high-pressure common-rail fuel system of a diesel engine. A fog dissipater body (2) is sleeved at the front end of a common-rail fuel injector assembly, an inner sleeve (3) is arranged at the front end of the fog dissipater body (2), an inner cavity of the inner sleeve (3) is provided with a fuel collection chamber (11) which corresponds to the common-rail fuel injector assembly, a sealing sleeve (4) which corresponds to the common-rail fuel injector assembly is arranged in the inner sleeve (3), a sealing ring (5) which corresponds to the common-rail fuel injector assembly is arranged in the sealing sleeve (4), a sealing gasket (7) is arranged between the inner sleeve (3) and the sealing sleeve (4), the inner sleeve (3) is connected with an outer sleeve (6), a chamber (9) is formed between the inner sleeve (3) and the outer sleeve (6), the upper part of the chamber (9) is open, the lower part of the inner sleeve (3) is provided with a small hole (8) for communicating the fuel collection chamber (11) and the chamber (9), and the lower part of the outer sleeve (6) is provided with a conical tip (10). The fog-dissipating fuel collector used for fuel injector experiments of a high-pressure common-rail fuel system of a diesel engine can meet the requirements of fog dissipation and fuel collection, and the fuel cannot leak from the upper part of the fog-dissipating fuel collector.
Description
Technical field
The utility model relates to a kind of oil trap, particularly relates to a kind of diesel engine high-pressure co-rail oil-fired system oil sprayer test fog dispersal oil trap.
Background technique
In the diesel engine high-pressure co-rail oil-fired system being studied, analyze, tests, is manufactured process such as factory's factory inspection and ECU (Electrical Control Unit) (ECU) exploitation debugging etc., sometimes need on the oil spout test stand, carry out common-rail injector oil spout test, test relevant parameters such as fuel injection quantity.At present, if do the work of these aspects, be to buy external high-pressure common rail oil-fired system test stand substantially, but valency is very high, substantially more than 1,000,000 yuans.By traditional fuel injection pump tester in upright arrangement is transformed, built common-rail injector oil spout test stand, but test is found, because common-rail injector cracking pressure height, tradition fuel injection pump tester in upright arrangement institute can not satisfy the requirement of its fog dispersal oil-collecting with the fog dispersal oil trap, and oil can spill from the oil trap top that disperses fog.
The model utility content
Technical problem to be solved in the utility model provides the requirement that a kind of energy satisfies the fog dispersal oil-collecting, and the diesel engine high-pressure co-rail oil-fired system oil sprayer that oil can not spill from fog dispersal oil trap top is tested with the fog dispersal oil trap.
In order to address the above problem, the diesel engine high-pressure co-rail oil-fired system oil sprayer test fog dispersal oil trap that the utility model provides, the fog dispersal body can be sleeved on common-rail injector assembly front end, described fog dispersal body front end is provided with interior cover, the cover inner chamber is formed with and the corresponding collection chamber of described common-rail injector assembly in described, be provided with the big envelope corresponding in described in the cover with described common-rail injector assembly 1, be provided with in the described big envelope and the corresponding seal ring of described common-rail injector assembly, be provided with gasket seal between cover and the described big envelope in described, cover is connected with between overcoat and described interior cover and the described overcoat and is formed with chamber in described, described chamber top is uncovered, the cover bottom is provided with the aperture that is communicated with described collection chamber and chamber in described, and described overcoat bottom is provided with the awl point.
The diesel engine high-pressure co-rail oil-fired system oil sprayer test of adopting technique scheme is with the fog dispersal oil trap, and the fuel oil of common-rail injector ejection is in the inside and outside inner room of fog dispersal device that the is full of fuel oil collection of being dispersed fog.Oil overlaps the chamber that the aperture of opening the bottom flows into the inside and outside inner room of device that disperses fog in the fog dispersal device, overflow through the top of overcoat, collects the awl point of overcoat bottom along the outer wall of overcoat, and the graduated cylinder metering can be inserted in the sharp bottom of awl or natural back flow arrives fuel tank.The inside and outside inner room of fog dispersal device is compression fit or is threaded.Because the common-rail injector injection pressure is very high, present product has the 180Mpa of reaching, if not sealing, by its impulse force, the oil in the interior cover has by the phenomenon of extruding from top fog dispersal body.The utility model is provided with seal ring in the big envelope in the cover in the fog dispersal device, well solved this problem.
In sum, the utility model is the requirement that a kind of energy satisfies the fog dispersal oil-collecting, and the diesel engine high-pressure co-rail oil-fired system oil sprayer that oil can not spill from fog dispersal oil trap top is tested with the fog dispersal oil trap.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, at common-rail injector assembly 1 front end sleeve fog dispersal body 2 is housed, cover 3 in fog dispersal body 2 front ends are provided with, in cover 3 inner chambers be formed with the collection chamber 11 corresponding with common-rail injector assembly 1, in cover be provided with the big envelope 4 corresponding in 3 with common-rail injector assembly 1, be provided with the seal ring 5 corresponding in the big envelope 4 with common-rail injector assembly 1, be provided with gasket seal 7 between interior cover 3 and the big envelope 4, interior cover 3 is connected with between overcoat 6 and interior cover 3 and the overcoat 6 and is formed with chamber 9, chamber 9 tops are uncovered, interior cover 3 bottoms are provided with the aperture 8 of connected set oil pocket 11 and chamber 9, and overcoat 6 bottoms are provided with awl point 10.
Referring to Fig. 1, the body 2 that disperses fog vertically is placed on the fog dispersal device installation sleeve, and the fuel oil of common-rail injector assembly 1 ejection overlaps 3 collection chamber 11 by the fog dispersal collection in being full of the fog dispersal device of fuel oil.Oil aperture of opening of cover 3 bottoms 8 in the fog dispersal device flows into the chamber 9 of 6 in cover 3 and overcoat in the fog dispersal devices, overflow on top through overcoat 6, outer wall along overcoat 6 is collected the awl point 10 of overcoat 6 bottoms, and the graduated cylinder metering can be inserted in the bottom of awl point 10 or natural back flow arrives fuel tank.Interior cover 3 and 6 in overcoat are compression fit.Because common-rail injector assembly 1 injection pressure is very high, present product has the 180Mpa of reaching, if not sealing, by its impulse force, the oil in the interior cover 3 has by the phenomenon of extruding from top fog dispersal body 2.Be provided with seal ring 5 in the big envelope 4 of the utility model in interior cover 3, well solved this problem.
