Layout method of marine diesel engine control air pipeline

Abstract

According to the layout method for the marine diesel engine control air pipeline, in a three-dimensional digital-analog environment, according to the spatial position and size relation of an air distributor, a connecting block and a cylinder interface plate, the spatial interface position size and the key spatial trend are determined, and the overall relation form non-interference layout design is achieved; the requirement for controlling the logic relation arrangement of the air pipes is met, the control pipes are controlled to be reasonable and attractive in layout, waste of materials in the manufacturing link is reduced, production plans are planned as a whole, the production preparation time is shortened, the manufacturing efficiency is improved, the overall manufacturing cost is reduced, the pipe bending quality and consistency are good, and the requirement for the technical level of operators is lowered.

Description

technical field [0001] The invention belongs to the technical field of piping system design of marine diesel engines, and in particular relates to a layout method for controlling air piping of marine diesel engines. Background technique [0002] The marine high-power diesel engine is started by compressed air, that is, the compressed air enters the air distributor, and the distributor is sent to the cylinder in the working stroke through the cylinder starting valve according to the ignition sequence of the diesel engine, and the piston is driven to drive the rotation of the crankshaft. When the crankshaft reaches the limit When the speed is high, the fuel injected into the combustion chamber can ignite and burn by itself, so that the diesel engine can run normally; in the above-mentioned whole process, the compressed air enters the air distributor, and then the sequence of the main compressed air entering the cylinder is determined by the control air pipe, so that To realize...

Problems solved by technology

[0004] Therefore, adopting the method of reverse design drawings of sample pipes requires highly skilled operators and poor technical ability inheritance, which is not conducive to digital production; the pipe bending data after layout It is difficult to record, which is not conducive to information sharing; the proportion of accidental errors in on-site piping is too large, it is difficult to achieve the consistency of pipe fittings, which affects the overall appearance quality of the diesel engine; the time for existing pipe fittings is too long, which affects the overall production cycle of the diesel engine; , prone to staggered pipeline spaces, non-parallel pipelines in the same direction, and scattered high and low.

Seriously affect the appearance quality of the diesel engine, in summary, in view of the above problems, it is necessary to improve
