Abstract
The utility model relates to a piston ring of a diesel engine, and the piston ring is a part which plays a sealing role in a diesel engine cylinder. The power of the diesel engine is directly influenced by the sealing performance of the piston ring. Compared with the thickness of the present ring, the thickness of the improved ring is reduced by one half, two rings are arranged in one ring groove, ring openings are mutually staggered by 180 DEG, therefore, the problem of air leak caused by the enlarged opening gap of the piston ring can be avoided, and the service life of the piston ring can be extended more than three times. The carbon black emitted from the back end of the cylinder is reduced greatly, the engine oil in a crankcase can not be contaminated, the service life of the engine oil can be extended more than three times, further, the pressure in the cylinder can not be reduced, the power of the diesel engine is increased, and the annually saved expenditure of each 195 type diesel engine can achieve 55 yuan.
Description
Piston ring of diesel engine is the major part that seals in the diesel engine cylinder.
At present, China's diesel engine, what great majority adopted is the cast-iron alloy ring.Monocycle list groove is adopted in the design and installation of this ring, and promptly a ring is contained in the annular groove, dress 3-5 road ring in the cylinder, and collar extension staggers mutually, plays seal action.Use through reality, this ring has two kinds of disadvantages: 1, along with the diesel engine prolongation of service time, the opened gap of ring increases gradually, and the phenomenon that leaks air causes the inner cylinder pressure deficiency, and power descends.2, not clean-burning diesel oil becomes carbon black, scurries in the crankcase through gap-clearance of piston rings with gas, pollutes machine oil, makes carbon black concentration increase in the machine oil.
In order to overcome above-mentioned disadvantage, now piston ring is changed a social system./ 2nd, two rings of the reduced thickness of former cast-iron alloy ring are contained in the annular groove, collar extension stagger 180 the degree.Assembling like this, effect is fine.Through the operation instruction over 2 years, be in whole sealing status in the cylinder.As scheming: figure one is former piston ring, and figure two is the piston rings after the transformation of the way.Middle osculum is gap-clearance of piston rings.With 195 diesel engines is example, and 195 type compression ring thickness are 3 millimeters, change system into 1.5 millimeters thick, the ring of two 1.5 millimeters thick is installed in the piston ring groove, opening stagger 180 the degree.The transformation of the way is assembled with following advantage like this:
1, under the constant condition of metallic material, can prolong 3 times the service time of piston ring.(be that former monocycle opened gap just can not be used greater than 2 millimeters again, existing dicyclo opened gap reaches 6 millimeters phenomenons that also can not leak air).
2, do not pollute machine oil.Ring after the transformation of the way is in whole sealing status at work always, can be isolated combustion gas and machine oil, and machine oil is prolonged more than 3 times service time.
3, the diesel engine cylinder internal pressure does not reduce, and has improved the power of diesel engine.
This reform is not increasing material, does not change under the situation of material, just can prolong complete machine running time, reduces amount of maintenance.Calculate with one 195 diesel engine, can save 55 yuan more than in 1 year.
This reform on all reciprocating compressors, all can be adopted, and the significant social economic benefit is arranged.
Claims (1)
1, a kind of piston ring of diesel engine is characterized in that, the thickness of this piston ring is 1/2nd of piston ring groove thickness, and two piston collar extensions, 180 degree that stagger place annular groove during use.
