Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of modular cylinder cover, can reduce the operating temperature of cylinder liner, improves the wear-resisting property of cylinder liner, improves the life-span of cylinder liner, reduces the manufacture cost of cylinder liner.
Technological scheme: for achieving the above object, modular cylinder cover of the present invention, comprise body, cylinder liner outer ring and cylinder liner inner ring, described cylinder liner outer ring is positioned at body, described cylinder liner inner ring inserts in cylinder liner outer ring, the inner and outer wall of cylinder liner outer ring is equipped with spirality cooling bath, the spiral inner wall shape cooling bath two ends of cylinder liner outer ring go out pipe with internal layer cooling liquid inlet pipe with internal layer cooling liquid respectively and are communicated with, the outer wall spirality cooling bath of cylinder liner outer ring goes out pipe with outer cooling liquid inlet pipe with outer cooling liquid respectively and is communicated with, spiral inner wall shape cooling bath adopts high-strength material.
As preferably, the length of described cylinder liner inner ring is 0.4 ~ 0.6 of cylinder liner outer ring length, and cylinder liner inner ring is concordant with upper end, cylinder liner outer ring.
As preferably, the lower end of described cylinder liner inner ring is cone table shape, and cylinder liner outer ring is provided with the conical bore coordinated with cone table shape.
As preferably, the upper end of described cylinder liner inner ring is provided with step.
As preferably, the inwall of described cylinder liner outer ring and cylinder liner inner ring and piston contact is provided with several equally distributed pits.
Beneficial effect: modular cylinder cover of the present invention, has the following advantages:
(1) this modular cylinder is arranged with inside and outside two spirality cooling baths, cooling liquid by cylinder liner high-temperature area spiral flow to low-temperature region, effectively can improve the radiating efficiency of cylinder liner, reduce temperature during cylinder liner work, and then improve piston, cylinder liner working environment.
(2) this modular cylinder is arranged with inside and outside two cooling baths, and the temperature of outer cooling bath is lower than internal layer, not easily produces cavitation pitting; Although internal layer cooling bath temperature is higher, what the high-temperature part employing of cavitation pitting easily occurred in inner side is high-strength material, can resist the impact that bubble breaks, not easily produce cavitation pitting, thus improve the resistance to pitcorrosion energy of cylinder liner.
(3) this modular cylinder is enclosed within that cylinder liner is easy to wear, frangible regions is provided with removable cylinder liner inner ring; Cylinder liner inner ring adopts high temperature resistant, wear-resisting, high-strength material, can significantly improve the wear-resisting property of cylinder liner; Cylinder liner outer ring adopts common material, can decrease cost of material and the processing cost of cylinder liner.
(4) this modular cylinder is enclosed within cylinder liner inner ring and is provided with a circle small stair near one end of cylinder head, can facilitate dismounting and the replacing of cylinder liner inner ring, can wipe the carbon distribution on piston ring off simultaneously, thus reduces the wearing and tearing of piston and cylinder sleeve.
(5) this modular cylinder is enclosed within the internal surface contacted with piston friction and is provided with uniform tiny pit, Lubricants can be stored, thus the surface making cylinder liner contact with piston friction easily forms oil film, improve the greasy property of cylinder liner and piston, reduce the friction of cylinder liner and piston, and then reduce the frictional loss of motor.
