Problems solved by technology

[0006] For a diesel generator set used in a certain type of power station, the length of the short shaft coupling connected to the shaft is nearly 1m, that is, the distance between the crankshaft coupling of the diesel engine and the shaft coupling of the generator is nearly 1m. The centering operation is carried out by erecting the magnetic base and the dial indicator on the wheel, and the generator shaft is long and heavy, so it is impossible to directly turn it by manual wheel-to-wheel

Abstract

The invention belongs to the technical field of generator set maintenance devices, and particularly relates to a centering device for a diesel generator set for a power station. The centering device comprises a barring tool and a coupling centering tool; and the generator set is centered through the barring tool and the coupling centering tool jointly. The diesel generator set for the power station can be centered quickly and efficiently before first installation or after faulty maintenance.

Description

technical field [0001] The invention belongs to the technical field of maintenance devices for generator sets, and in particular relates to a centering device for diesel generator sets used in power stations. Background technique [0002] Diesel generator set for power station is a large-scale rotating equipment. If the centerlines of the crankshaft of the diesel engine and the shaft of the generator are not on the same straight line, it will inevitably cause the vibration of the diesel generator set to exceed the standard, and even cause equipment damage in severe cases. [0003] Therefore, the alignment of the crankshaft of the diesel engine and the shaft of the generator is an important task for the maintenance of the diesel generator set. , The end face deviation is within the specified value. [0004] The purpose of aligning the crankshaft of the diesel engine and the rotating shaft of the generator is to make the centerline of the rotating shaft of the generator and t...
