Problems solved by technology

The traditional one-piece casting cooling chamber cylinder liner may block the cooling channel due to difficulty in sand removal, or cause poor cooling effect due to uneven casting wall thickness, which will lead to abnormal operation of the diesel engine due to cooling problems, and in severe cases, parts will be scrapped

Abstract

The invention discloses an air cylinder sleeve for a two-stroke diesel engine and a processing method for the air cylinder sleeve. The air cylinder sleeve comprises a cylinder sleeve body, a water sleeve, a water inlet flange, a water separator and a connecting stud, wherein an inner hole of the cylinder sleeve body is divided into an upper straight-hole section, a middle drum-shaped hole sectionand a lower straight-hole section which communicate with one another from top bottom; the water sleeve comprises an upper water sleeve and a lower water sleeve, and are separately brazed on the cylinder sleeve body to form an upper cooling water cavity and a lower cooling water cavity; the water inlet flange is welded on the lower water sleeve; the water separator is assembled in the water inlet flange; and the connecting stud is arranged at the upper end of the cylinder sleeve body. The two-stroke diesel engine disclosed by the invention can improve friction wear performances of the cylindersleeve, improves scavenging efficiency, and improves the cylinder sleeve cooling effect, so that the service life is prolonged and energy consumption is reduced.

Description

technical field [0001] The invention relates to a cylinder liner for a two-stroke diesel engine, and also relates to a processing method for the cylinder liner. Background technique [0002] As a widely used engineering machinery, two-stroke diesel engine has always been the performance index that the industry pays close attention to for its lubrication, friction and wear, combustion efficiency, energy consumption and fatigue life. As an important part closely related to the above-mentioned research proposition, the cylinder liner's structure design and processing method have always been a hot topic in the research and discussion of various diesel engine parts enterprises. [0003] Two-stroke diesel engines are usually equipped with one-way scavenging of the cylinder space. The scavenging efficiency and the wear of the inner hole of the cylinder liner and the piston ring near the scavenging are directly related to the service life of the diesel engine. How to improve the sc...
