Multi-cylinder scavenging chamber casting for seagoing vessel

Abstract

The invention relates to the technical field of seagoing vessel engine equipment, in particular to a multi-cylinder scavenging chamber casting for a seagoing vessel. The multi-cylinder scavenging chamber casting comprises a scavenging chamber body of which the inner part is provided with a cut-through cavity, wherein the two ends of the scavenging chamber body are separately provided with connecting discs, and cooling channels arranged in the length direction of the scavenging chamber body are separately arranged in the inner walls of the middles of the two sides of the scavenging chamber body; two groups of upper assembling holes are symmetrically formed in the upper parts of the two sides of the scavenging chamber body along the axis of the scavenging chamber body, each group of upper assembling holes comprises a plurality of assembling holes, and the bottom of the scavenging chamber body is provided with one group of bottom assembling holes; and reinforcing platforms projecting out of the scavenging chamber body are separately arranged in the middles of the two sides of the outer wall of the scavenging chamber body, and technical holes communicating with the cooling channels are formed in the reinforcing platforms. The structure design of the multi-cylinder scavenging chamber casting is reasonable, heat in the scavenging chamber body can be diffused, the temperature in the scavenging chamber is reduced in a work process, and the size precision and strength of the scavenging chamber body can be ensured.

Description

technical field [0001] The invention relates to the technical field of seagoing ship engine equipment, in particular to a multi-cylinder scavenging chamber casting for seagoing ships. Background technique [0002] The engine needs fresh oil-air mixture to "squeeze" the burned exhaust gas out of the cylinder. This process is called scavenging. It can be seen that the scavenging process is to provide fresh oil-air mixture to the engine to enhance the power of the engine, thereby The temperature in the scavenging chamber is high; however, due to the unreasonable setting of the castings in the scavenging chamber, there are still certain defects in the dimensional accuracy of the castings, the heat dissipation performance and the overall strength of the castings. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a multi-cylinder scavenging chamber casting for sea-going vessels with reasonable structural design, ...
