Piston Orbis.
Piston anulus est ad inserere in Piston sulcus intra metallum circulum, Piston circulum dividitur in duas genera: compressam circulum et oleum anulum. Et compressio anulus potest esse signare combustibili mixturam Gas in combustione cubiculum; Et oleum anulum adhibetur ad rade excessus oleum de cylindro. Piston anulus est quaedam metallum elastica anulum cum magna exteriori expansion deformatio, quae convenerunt in profile et correspondentes annularis sulcus. Reciprocating et rotating Piston annulos confidunt in pressura differentia Gas aut liquidum ad formare sigillum inter exteriores circulus circulum et cylindrum et latus circulum et anulum sulcus.
Scope of application
Piston rings are widely used in a variety of power machinery, such as steam engines, diesel engines, gasoline engines, compressors, hydraulic presses, etc., widely used in cars, trains, ships, yachts and so on. Plerumque in Piston Orbis est installed in anulus sulcus Piston, et quod Piston, cylindri liner, cylindrici capite et alias components de thalamo ut opus.
Piston Anulus est Core Component intra cibus engine, et cylindri, piston, cylindrum murus simul ad perficiendum sigillum cibus Gas. Commonly used automotive engines have two kinds of diesel and gasoline engines, due to their different fuel performance, the use of piston rings are not the same, the early piston rings are formed by casting, but with the progress of technology, steel high-power piston rings were born, and with the function of the engine, environmental requirements continue to improve, a variety of advanced surface treatment applications, such as thermal spraying, Electroplating, Chrome plating, etc Gas nitriding, corporalis depositione, superficiem coating, cadmiae manganese phosphasting curatio, etc., magno amplio functionem Piston anulum.
Piston Orbis function includit signantes, regulating oleum (oleum imperium), calor conduction (calor translatione), ductu (suscipio) quattuor numeribus. Obsinting: refers to sainting Gas, ne sit combustion aethereum Gas Leakage ad crankcase, in Gas Leakage regitur ad minimum, improve thermal efficientiam. Aeris Leakage non solum reducere potestas engine, sed etiam oleum deteriorationis, quae est pelagus opus de Gas circulum; Adjust the oil (oil control) : the excess lubricating oil on the cylinder wall is scraped off, and the cylinder wall is covered with a thin oil film to ensure the normal lubrication of the cylinder and piston and ring, which is the main task of the oil ring. In modern summus celeritate engines, specialem operam est solvit ad partes Piston anulum imperium oleum film; Calor Conduction: Quod calor Piston est traducitur ad cylindri liner per Piston circulum, id est refrigerationem effectus. Secundum ad reliable data, LXX ~ LXXX% de calore accepit a piston summo de uncoled Piston est dispersit per Piston anulum ad cylindrum murum, et XXX ~ XL% of refrigerationem Piston est dispersit per Piston circulum ad cylindrum murum; Support: De Piston Orbis custodit Piston in cylindrici, prohibet directum contactus inter Piston et cylindri murum, ensures lenis motus piston, reduces frictio resistentia, et impedit piston a pulsans cylindri. Fere, in Piston de Gasoline engine utitur duo Gas annulos et oleum anulum, cum Diesel engine plerumque utitur duo oleum annulos et unum Gas circulum.
Bonum et malum idem
The working surface of the piston ring shall not have nicks, scratches, peeling, the outer cylinder and the upper and lower end surfaces shall have a fixed finish, the curvature deviation shall not be greater than 0.02-0.04 mm, the standard subsidence of the ring in the groove shall not exceed 0.15-0.25 mm, and the elasticity and clearance of the piston ring meet the requirements. In addition, we should also check the light leakage of the piston ring, that is, the piston ring is flat in the cylinder, put a small lamp under the piston ring, put a light screen above, and then observe the light leakage gap between the piston ring and the cylinder wall, which shows whether the contact between the piston ring and the cylinder wall is good. Sub normalis fortuna, lux Leak roam de Piston circulum metiri cum crassitudine METIOR non excedunt 0.03 mm. Longitudo continua lucis leakagium non esse maius 1/3 cylindrici diameter longitudinem numerus lucis lacus diametrum maiore 1/3 lacus non excedat. Piston Orbis Terrarum GB / T 1149.1-94 Dat speciem omnes Piston Annulorum requiritur habere adscendens directionem et alibi in superiore parte, quod est latus proxime ad combustionem cubiculum. Annuli notata superioris latere includit: Circulum circulum, interiorem Chamfer, exterius secans mensam circulum, nasum anulum, cuneo circulum et oleum anulum requiring installation direction et superius anulum signa.
