The machine oil of small-sized internal combustion machine testing places closed circuit system
Technical field
The utility model belongs to checkout equipment technical field, and the machine oil refering in particular to small-sized internal combustion machine testing places closed circuit system.
Background technology
Existing compact internal combustion engine is when detecting its body performance, need to inject machine oil to detect, upon completion of the assays, machine oil is then needed to pour out, in this testing process, required for some infrastructure devices of relating to be: oil storage tank (fuel tank), connect oil storage tank oil pump, be connected with oil pump, oil storage tank that the oil gun that carries out oiling to compact internal combustion engine, the machine oil poured out are deposited; At present, the design comparison of prior art is simple, and the machine oil poured out needs a dead lift again to utilize to oil storage tank, and the process of this carrying can cause the of short duration stagnation detecting streamline; Or need to increase oil storage tank for laying in replacing; The defect that prior art exists as can be seen here is: one is the reduction that the stagnation of detection line causes detection efficiency; Two is that a dead lift needs human cost and time cost; Three is need to increase oil storage tank for subsequent use to add use cost, therefore addresses the aforementioned drawbacks, the business efficiency can further improve the efficiency of production, reducing production cost, greatly promote producer.
Summary of the invention
The machine oil that the purpose of this utility model is to provide a kind of small-sized internal combustion machine testing places closed circuit system.
The purpose of this utility model is achieved in that
The machine oil of small-sized internal combustion machine testing places closed circuit system, it is characterized in that: the starting end of gasoline engine transfer passage is provided with main oil storage tank; Tail end is provided with recovery oil storage tank, described recovery oil storage tank connects main oil storage tank by return line, described main oil storage tank connects oil pump and oil gun successively by pipeline, described oil gun refuels to the gasoline engine being positioned at gasoline engine transfer passage starting end, the gasoline engine being positioned at tail end is drained the oil to recovery oil storage tank, reclaims oil storage tank by scavenge pipe oil transportation to main oil storage tank.
Place in closed circuit system at the machine oil of above-mentioned small-sized internal combustion machine testing, described gasoline engine transfer passage is the automatic delivering belt controlled by controller.
Place in closed circuit system at the machine oil of above-mentioned small-sized internal combustion machine testing, described main oil storage tank and the junction of scavenge pipe are provided with retaining valve.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, the utility model saves manpower, and the machine oil put upside down out after small-sized internal combustion machine testing completes directly is back to main oil storage tank by scavenge pipe, avoids manually moving back and forth oil storage tank, saves manual operation.
2, after the utility model practical application, define the closed circuit system of a machine oil, detect streamline and can not there is the phenomenon stagnated because adding machine oil, maintain and detect the coherent of streamline and duration performance, improve the efficiency of detection.
3, the utility model directly can be transformed on existing equipment, transforms simple and quick.
4, the utility model utilizes original oil pump to be drawn in oil storage tank by the machine oil reclaimed in oil storage tank, without the need to increasing new dynamic structure, with low cost.
5, the utility model is not owing to needing moved by hand oil storage tank, avoiding the pause detecting streamline, because this reducing production cost, and improves the economic benefit of producer.

Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1:
The machine oil of small-sized internal combustion machine testing places closed circuit system, and the starting end 2 of gasoline engine transfer passage 1 is provided with main oil storage tank 3; Tail end 4 is provided with and reclaims oil storage tank 5, described recovery oil storage tank connects main oil storage tank by return line 6, described main oil storage tank connects oil pump 7 and oil gun 8 successively by pipeline, described oil gun refuels to the gasoline engine being positioned at gasoline engine transfer passage starting end, the gasoline engine being positioned at tail end is drained the oil to recovery oil storage tank, reclaims oil storage tank by scavenge pipe oil transportation to main oil storage tank.
The course of work of the present utility model is: see in Fig. 1 shown in arrow: the machine oil in main oil storage tank 3 is extracted out by oil pump 7, inject in gasoline engine by oil gun 8, then gasoline engine moves ahead along with gasoline engine transfer passage 1, in the process of moving ahead, carry out every detection, when gasoline engine marches to the tail end 4 of gasoline engine transfer passage 1, artificial or machinery takes off gasoline engine, machine oil in gasoline engine is poured out, down in recovery oil storage tank 5, be connected by return line 6 with between main oil storage tank 3 owing to reclaiming oil storage tank 5, therefore when oil pump 7 works, the machine oil reclaimed in oil storage tank 5 is pumped down in main oil storage tank 3 automatically.
Described gasoline engine transfer passage is the automatic delivering belt controlled by controller.
Described main oil storage tank and the junction of scavenge pipe are provided with retaining valve 9.The effect of retaining valve prevents oil level in main oil storage tank 3 from producing oily phenomenon generation of flowing backwards higher than reclaiming oil level in oil storage tank 5.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
