Problems solved by technology

The cargo oil pump turbine and the cargo oil pump are connected to each other through the short shaft, the intermediate shaft and the floating shaft of the sealing device, and are installed in the engine room and the pump room respectively. Since the two devices are installed in different sections and the distance is relatively long, and the axes of the two devices are aligned High precision is required, the work of alignment is difficult and prone to human errors

Embodiment Construction

[0027] Make temporary shaft tooling: Consider the weight and use strength of the tooling, and the machining accuracy of the flange to ensure that the tooling is easy to use and easy to install. The temporary shaft flange can be connected with the output shaft flange of the cargo oil pump for zero-to-zero alignment. The segmental hoisting of the engine room and the pump room is completed, and the segmental hoisting of the tail area general group is completed.

[0028] 1. Positioning of the cargo oil pump: According to the layout position of the cargo oil pump installation drawing, draw a line on the double bottom of the pump room to determine the center position of the base of the cargo oil pump. Measure the height distance from the centerline of the cargo oil pump suction inlet flange to the inner bottom of the pump room. Check whether the distance between the base panel of the cargo oil pump and the base panel meets the installation requirements, and adjust the level of the c...

Abstract

The invention relates to a cargo oil pump and turbine mounting and aligning method. The method includes: machining a temporary shaft, using the temporary shaft on a cargo oil pump or a turbine, and using a dial indicator and a feeler gauge to perform position measurement and adjustment so as to realize cargo oil pump and turbine mounting positioning and aligning. The method has the advantages that a floating shaft is replaced by the temporary shaft, instruments are rested on the temporary shaft for alignment and mounting, construction is convenient, tool manufacturing cost is lower, operation is simple, construction staff can understand and master easily, error rate during construction is low, equipment mounting precision is increased, and the method is applicable to cargo oil pump and turbine mounting and aligning.

Description

technical field [0001] The invention relates to the field of installation of cargo oil pumps and turbines of oil tankers, and is mainly used in the installation of cargo oil pumps and turbines of cargo oil pumps in docks, and specifically relates to a method for aligning the installation of cargo oil pumps and turbines. Background technique [0002] Oil tanker cargo oil system generally adopts 3 cargo oil pumps and 3 cargo oil pump turbines. The cargo oil pump turbine and the cargo oil pump are connected to each other through the short shaft, the intermediate shaft and the floating shaft of the sealing device, and are installed in the engine room and the pump room respectively. Since the two devices are installed in different sections and the distance is relatively long, and the axes of the two devices are aligned It requires high precision, and it is difficult to find the work and it is easy to produce human errors. The method of the present invention will aim at the above...
