Description
Technical Field
The invention relates to the technical field of generator set tests, in particular to a device and a method for testing the oil injection condition of an oil injection nozzle in a generator set target test.
Background
At present, a plurality of 1000kw generator sets are in operation, a cylinder-pulling phenomenon without faults often occurs, so that a piston and a cylinder sleeve are scrapped, and in the process of inspection, a direct reason is difficult to find out. According to the experience of a unit maintenance master of our company, the reason for generating cylinder pulling of an engine is mainly caused by the fact that lubricating oil is not available at present. Lubricating oil is stored at the bottom of an oil pan of the unit, enters a main oil duct in the engine body after being pressurized by an oil pump, and is accurately sprayed into an oil hole of the piston through an oil nozzle arranged on the main oil duct, so that a piston moving part and a cylinder sleeve are continuously lubricated.
The oil nozzle integrally comprises an oil pipe nozzle, a hollow screw and an oil plug which are welded on the oil nozzle body, and the oil pipe nozzle has a certain bending angle; in addition, when the engine body operates, the flow direction principle of the oil way is as follows: oil pan → oil pump → main oil duct → body nut → nozzle, the main oil duct has oil pressure when the unit operates in addition, and oil can enter the nozzle oil spout, and when the unit does not operate (shut down when repairing in the middle of, the no oil pressure can not inspect the oil spout phenomenon, and the oil pipe nozzle is inside the organism, can not directly look over the oil spout condition.
Because the oil pipe nozzle is welded on the main body of the oil nozzle device, the following reasons are possible to occur, 1, because the welding is not firm, the cold joint condition exists. 2. During welding, a sand hole (oil drainage from the sand hole during operation) 3 exists, and the bending angle of the oil pipe nozzle is not correct. (when the oil jet is caused, the oil beam sprayed from the oil pipe nozzle can not be accurately sprayed into the oil hole of the piston)
Because the maintenance of fuel sprayer is very troublesome, when doing the maintenance in the past, only singly dismantle the fuel sprayer, diesel oil washs one time, and the visual inspection is once again, does not have big problem and installs again, and can't really inspect the oil spout condition how, can't go the experiment, and whether inside is unobstructed, so brought the trouble for maintenance work, this department inspection is still blank stage at present. Accordingly, it is desirable to invent a device and a method for testing the oil injection condition of an oil injection nozzle in a generator set targeting test.
Through analysis, in the target test, the difficulty of checking the oil injection condition of the oil injection nozzle mainly comprises the following aspects: 1. under the condition of not starting up, the oil nozzle needs oil pressure, so that oil can be sprayed out from the nozzle of the oil nozzle, and the oil pressure needs to be ensured on the premise of checking the oil spraying condition; 2. the oil nozzle is shielded by a crank or a balance block, and the space gap in the position is narrow, for example, the balance block on a generator set of the factory is tightly attached to the oil nozzle, and the gap in the middle is extremely small, so that the oil injection condition of the oil nozzle cannot be directly checked; 3. the main oil duct has no oil, so that the oil in the oil nozzle is ensured; 4. if only the oil nozzle is disassembled by adopting the traditional method, the oil nozzle cannot be installed in place after being cleaned and reinstalled; 5. if the oil injection condition is checked by using the pre-oil supply pump of the unit, the observation ports of the 16 cylinders cannot be installed and sealed, when oil is pumped, the oil injection nozzle and an oil way which is not sealed on the unit can leak oil simultaneously, a large amount of lubricating oil is leaked, the effect is not ideal, the observation time is limited, the oil injection condition cannot be clearly seen, the oil injection nozzle only injects oil in a single row, the other row cannot spray oil, and the inspection effect is not good.
