Calibration device, method of making calibration device, and method of using calibration device

Abstract

The invention discloses a manufacturing method of a correction device. The manufacturing method comprises the following steps that a simulated assembly drawing of the correction device is drawn according to a drawing of an expansion joint; an assembly part drawing and an auxiliary part drawing are drawn according to the simulated assembly drawing, wherein the assembly part drawing is the drawing of parts for forming the correction device, and the auxiliary part drawing is the drawing of temporary parts used when the correction device is assembled; according to the assembly part drawing and theauxiliary part drawing, assembly parts and auxiliary parts are manufactured respectively; and the correction device is assembled according to the simulated assembly drawing. The invention further discloses the correction device manufactured by the manufacturing method and a using method of the correction device. By means of the correction device, rainwater can be prevented from entering a dieselengine, a smoke exhaust pipe can be conveniently corrected, and the expansion joint can be prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of marine diesel engine installation, in particular to a calibrating device, a manufacturing method and a using method thereof. Background technique [0002] As the main power plant of a ship, the diesel engine usually takes several months from hoisting on board to complete installation of the system to meet the requirements of use. During this period, it is necessary to effectively protect the diesel engine, especially to prevent the diesel engine from entering water. There are two traditional protection methods to prevent diesel engine from water ingress: the first method is to install a flange blind plate directly at the exhaust outlet of the diesel engine; the second method is to install an expansion joint directly at the exhaust outlet of the diesel engine, and A white iron blind plate is installed at the expansion joint and the exhaust outlet of the diesel engine. [0003] Generally, when installing ...

AI Technical Summary

Problems solved by technology

However, the above two protection methods have their own disadvantages when installing the smoke exhaust pipe.

Disadvantages of the first method: when installing the exhaust pipe, it is necessary to temporarily install the expansion joint of the exhaust outlet of the diesel engine. After the exhaust pipe is adjusted, the expansion joint is removed and the protective blind plate is installed. This method is time-consuming It is laborious, and the installation efficiency of the exhaust pipe is low. At the same time, the expansion joint is repeatedly disassembled, and the expansion joint is easily damaged.

Disadvantages of the second method: install a white iron blind plate at the exhaust outlet of the expansion joint and the diesel engine, the sealing effect of the white iron blind plate is poor, water is easy to accumulate inside the expansion joint, and water is easy to leak into the diesel engine when the white iron blind plate is removed , and for a long time to directly use the expansion joint to adjust the exhaust pipe, it is easy to deform the expansion joint
