Explain the foundation and shock absorption function of diesel generator set in detail?
2021-06-25
A rigid underframe is used to accurately install the alternator and engine. Therefore, when installing the generator set, it only needs to be fixed on a good foundation with screws.
Basics:
The best foundation is to build a reinforced concrete block to install the generator. The foundation provides a rigid support for the generator set to prevent swing and vibration. The standard cement block shall be 150 MM-200 mm (6-8 inches) thick, and the area shall not be less than that of the generator set underframe. The ground or floor under the foundation plate shall be prepared in advance to support the weight of the foundation plate plus the generator set（ If the generator set is to be installed above the ground level, the structure of the building must be able to bear the weight of the generator set and the stored fuel and accessories, etc.) The building must comply with the local building regulations. If the floor is often wet (such as in the boiler room), the foundation must be higher than the floor, so as to provide a place for the generator set, facilitate the wiring and maintenance of workers, and minimize the metal corrosion of the underframe.
shock absorption:
In order to reduce the vibration of the generator set to the building as much as possible, the generator set is equipped with shock absorber, which is installed between the engine / alternator foot and the underframe. This allows the underframe to be fixed directly to the foundation. For larger generator sets, the engine / alternator is rigidly fixed on the underframe, with shock absorbers attached for installation between the frame and the foundation. In any case, the generator set shall be firmly bolted to the ground to prevent movement.

The external connections of diesel generator set need damping connection, such as soft fuel pipe, exhaust hose, exhaust pipe soft interface, wire hose and other connection support system, etc.
