Description

Diesel generating set falls device of making an uproar with giving sound insulation

Technical Field

The utility model relates to a unit vibration isolation technical field specifically is a device of making an uproar falls in giving sound insulation for diesel generating set.

Background

The diesel engine drives the generator to run, the energy of the diesel oil is converted into electric energy, clean air filtered by an air filter is fully mixed with high-pressure atomized diesel oil sprayed by an oil nozzle in a cylinder of the diesel engine, and the clean air is extruded by a piston to reduce the volume and quickly rise the temperature to reach the ignition point of the diesel oil, so that the diesel oil is ignited, the mixed gas is violently combusted, the volume is quickly expanded, and the piston is pushed to move downwards, namely 'doing work'. The cylinders do work in sequence, the thrust acting on the piston is changed into the force pushing the crankshaft to rotate through the connecting rod, so that the crankshaft is driven to rotate, the brushless synchronous alternating-current generator and the crankshaft of the diesel engine are coaxially arranged, the rotor of the generator can be driven by the rotation of the diesel engine, the generator can output induced electromotive force by utilizing the principle of 'electromagnetic induction', and the current can be generated through a closed load loop.

Before the generating set installation, should strictly carry out the vibration isolation according to the relevant data that the producer provided and handle, avoid causing the remote propagation of structure sound, because generating set's weight is not balanced, do not have evenly distributed, consequently owing to lack the structure in the current generating set vibration isolation structure use, make the generating set when installing these vibration isolation structures, the great one end of unit weight is compared in the less one end of weight degree of sinking on the vibration isolation structure and inconsistent, thereby lead to the generating set installation unbalanced, need put just can be balanced with the help of other structures pad, the trouble of ten minutes is got up in the use.
