Abstract
The invention relates to a method for prolonging life of a stored missile engine. According to the technical methods for overhauling a life prolonging prototype, detecting the state of parts, testing the performance of the parts, performing an accelerated ageing test on nonmetal parts and mechanical and electrical products, restoring and assembling the aged parts, performing complete machine test run testing and the like, weak parts which influence the long-term storage of the engine and the longest calendar life of the engine are determined, the longest calendar life serves as the longest calendar life of the missile engine, and the aims of fully exerting utilization benefits of military hardware and reducing the overhaul cost are fulfilled.
Description
Technical field
The present invention relates to a kind of engine life-prolonging method, especially a kind of bullet is stored life-prolonging method with engine.
Background technology
The bullet engine is by the complex product that rotating machinery, electronic product and priming system etc. form, and relates to a plurality of specialties such as intensity, pneumatic, burning, chemical industry and electronics, and determining of its calendar life is very difficult.At present, the leading mode of using of domestic general employing, prolong the technical method of calendar life after not having systematic bullet to store with aeromotor, especially import bullet engine, namely need to overhaul to the longevity, the cycle is long, and expense is high, can't give full play to import weaponry utilization benefit, affect combat effectiveness of the troops; The domestic bullet of active service adopts the leading mode of using given with the engine calendar life is general, and the shortage science is determined the technical method of calendar life accurately.
Summary of the invention
The purpose of this invention is to provide a kind of bullet prolongs calendar life with engine method, grope storage property Changing Pattern, determine that impact stores the weak link of property, formulation science, reasonable, economic Engine Overhaul scheme.
Technology solution scheme of the present invention is that described method may further comprise the steps:
(1) choose at random model machine at the bullet in calendar phase to longevity in aeromotor, the quantity of model machine is not less than 1% and choose at least 5 and carry out the research work of lengthening the life;
(2) carry out the model machine visual examination, check whether engine exists leakage of oil, corrosion situation, surpass 20% or the situation of serious leakage of oil is arranged if be no less than 50% model machine corrosion area, then this batch calendar does not possess the condition of lengthening the life to the engine in longevity, ends to lengthen the life;
(3) extract at least 2 model machines and carry out the performance test run of knowing the real situation, check the overall performance attenuation degree, if the design objective performance degradation is all above 20% relatively, engine does not possess the condition of lengthening the life, and need overhaul or scrap and end and lengthen the life;
(4) extract at least 2 model machines and carry out overhaul, the state after inspection graphite annulus, rubber parts, electronic product, the part coating long term storage is determined the weak parts that affect the engine calendar life;
(5) carry out flexible member performance checking, nozzle flow test, oil pump performance test, determine parts performance degradation degree, determining according to the result affects the weak parts of engine calendar life;
(6) the weak parts that will determine, engine by its assembling divides into groups, wherein two groups are carried out at random the aging test of accelerated deterioration to 12 year and 16 years, the carry out a test Performance Detection of part of per 3 months test equivalent time in the process of the test, if the result shows performance degradation and surpasses 20%, be the longevity, adopt said method to determine that upward testpieces can be used storage life;
(7) oil sealing fuel oil, lubricating oil are carried out Performance Detection, determine its available storage life;
(8) with all Assembly of the parts to the former engine, wherein in process of the test the parts to the longevity to change new product, then examine test run and HIGHER ALTITUDE TEST FACILITY running-up test;
(9) according to the shortest calendar life of each part in the selected accelerated deterioration process as the calendar life of this bullet with engine, the i.e. extensible ultimate life of this wholesale motivation.
The advantage that the present invention has is can be by overhaul, part status detection, component characteristic test, nonmetal parts and the electronic product accelerated aging test of the model machine of lengthening the life, aging rear parts are recovered the technical methods such as assembling, complete machine test run checking, determining affects long-term weak parts and the longest calendar life thereof of storing of engine, use the longest calendar life of engine as bullet with this, reach and give full play to the weaponry utilization benefit, reduce the purpose of the expense of overhauling.
The present invention determines to affect bullet with the weak link of aeromotor storage property by above-mentioned detection, test, can formulate targetedly science, effectively overhaul scheme, saves cost, raises the efficiency.
The present invention is to active service and newly grind bullet and with the aeromotor calendar life is given certain reference arranged.
