Arrangement and installation method of foundation bolts of marine diesel engine on test bed

Abstract

The invention discloses an arrangement and installation method of foundation bolts of a marine diesel engine on a test bed. The method comprises the steps that 1, a plurality of general type test run iron benches are installed on the test bed; 2, the prearranged positions of the foundation bolts of the marine diesel engine are arranged according to the shafting arrangement and the model of the marine diesel engine; 3, the marine diesel engine is located on the test run iron benches for correction and leveling; 4, a pneumatic tool is installed and used for fastening the foundation bolts of the marine diesel engine; and 5, a torque wench is used for torque checking in a spot-checking manner; when all the checked fastening torques meet the requirement, arrangement and installation of the foundation bolts of the marine diesel engine on the test bed are completed. According to the arrangement and installation method, the problem that the foundation bolts of the marine diesel engine are complex and difficult to arrange is solved; the labor production efficiency is improved, and the labor intensity of operation is lowered; the safety of workers is improved, and meanwhile connection reliability of the foundation bolts of the marine diesel engine is ensured; and the method can be applicable to marine low-speed diesel engines of various models, and the requirement for arrangement and installation of the foundation bolts of the platform test bed of the diesel engine is met.

Description

technical field [0001] The invention relates to a production process of a marine low-speed diesel engine, in particular to a method for arranging and installing anchor bolts of a marine diesel engine on a test bench, and belongs to the technical field of diesel engine production. Background technique [0002] As we all know, marine low-speed diesel engines need to be run-in, debugged and other test items before leaving the factory. The diesel engine should be placed on a specific test stand for platform test. When the diesel engine is started and tested, unbalanced forces will be generated due to uneven force on the moving parts. These unbalanced forces mainly include the H-type overturning moment M that makes the main engine overturn and the X-type torsional moment T that makes the main engine twist. There is a superimposed force or moment generated by the vibration of the main engine. In order to ensure that the entire shafting of the diesel engine has strong rigidity dur...
