Abstract

The invention discloses a wet type cavitation erosion resisting cylinder sleeve. The wet type cavitation erosion resisting cylinder sleeve comprises a cylinder sleeve body, wherein the cylinder sleeve body is provided with a thickened wall, water cavity grooves which extend along the axial direction are processed in the outer circumferential face of the cylinder sleeve body at equal radian intervals, a reinforcing rib which can enhance rigidity of the cylinder sleeve body is formed between each two adjacent water cavity grooves, the outer cambered surface of each reinforcing rib is fully contacted with an engine cylinder block, and the water cavity grooves and the engine cylinder block cooperatively form a plurality of lengthways cooling water cavities evenly distributed in the outer circumferential face of the cylinder sleeve body. Due to the fact that the reinforcing ribs and the lengthways cooling water cavities are formed on the cylinder sleeve body, the rigidity of the cylinder sleeve body is greatly enhanced, and the wet type cavitation erosion resisting cylinder sleeve is small in deformation and vibration when a piston laterally impacts. Accordingly, cavitation erosion of the wet type cavitation erosion resisting cylinder sleeve is effectively prevented, use life of the wet type cavitation erosion resisting cylinder sleeve is prolonged, and furthermore the wet type cavitation erosion resisting cylinder sleeve has the advantages of being good in cooling effect, easy to process and convenient to maintain.
