Abstract

To solve the problem that the centering is difficult when a diesel engine with an integral support leg is connected to a dynamometer in the prior art, the invention provides a centering method of a diesel engine with an integral support leg and a dynamometer. The method comprises the steps of (S1) performing pre-centering on the dynamometer and a base of the diesel engine according to a designed size requirement, (S2) connecting the diesel engine, the integral support legs and the diesel engine base and connecting a connection high-elasticity unit and the dynamometer into a whole body, (S3) measuring the connection high-elasticity unit for one time by using a centering frame every fixed angle, recording axial and radial data, and adjusting the position of the diesel engine according to thedata, and (S4) repeating the step (S3) until technological requirements are met to complete the centering. According to the method, the radial and axial data of the diesel engine are measured every 90 degrees through the centering frame, then the diesel engine is adjusted according to the data, and the diesel engine and the dynamometer are connected in a centering mode step by step.

Description

technical field [0001] The invention relates to the technical field of oil production machine dynamometer, in particular to a method for centering a diesel engine and a dynamometer using an integral support foot. Background technique [0002] After the assembly of the diesel engine, it is necessary to perform a performance test on the diesel engine, that is, the diesel engine needs to be tested on a test bench. The existing diesel engines mostly use split feet for installation, alignment and test run. As users have higher and higher requirements for diesel engines , put forward higher requirements on vibration and noise, followed by the diesel engine using the integral test foot is the preferred option, the diesel engine using the integral foot for test centering and the diesel engine test alignment of the split foot have extreme Compared with the diesel engine test centering with split legs, the diesel engine centering with integral legs has more stringent requirements, and...
