Arrangement and Installation Method of Marine Diesel Engine Anchor Bolts on Test Bench

Abstract

A method for arranging and installing the anchor bolts of a marine diesel engine on a test bench, comprising the steps of: 1) installing several general-purpose test iron benches on the test bench; 2) arranging the anchor bolts of the marine diesel engine according to the shafting arrangement and model of the marine diesel engine 3) Seat the marine diesel engine on the test iron bench and correct the level; 4) Install and use pneumatic tools to fasten the anchor bolts of the marine diesel engine; When all the fastening torques sampled and checked all meet the requirements, the arrangement and installation of the anchor bolts of the marine diesel engine on the test bench is completed. The invention solves the problem of complex and difficult arrangement of anchor bolts of marine diesel engines, improves labor production efficiency, reduces labor intensity of operation, improves the safety of operators, and at the same time ensures the reliability of anchor bolt connection of diesel engines, and is applicable to It is suitable for various types of marine low-speed diesel engines, and meets the requirements for the arrangement and installation of anchor bolts for the diesel engine platform test run.

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...
