Abstract
The invention aims at providing a diesel generator with fixed rotating speed so as to enable a diesel engine to keep the optimal rotating speed throughout and improve generating efficiency. The diesel generator with the fixed rotating speed comprises the diesel engine and a generator fixed on a base. The diesel generator further comprises a transmission. An engine shaft of the diesel engine is connected with a driving shaft of the transmission through an elastic coupler, and a generator shaft is connected with a driven shaft of the transmission through the elastic coupler. The transmission can convert rotation with the fixed speed of the diesel engine into rotation with changing speed of the generator, rotating speed of the diesel engine is set as the rotating speed with the optimal energy utilization efficiency, and output power of the generator is adjusted by changing variable speed ratio of the transmission to adjust the rotating speed of the generator. In addition, due to the elastic coupler, most vibration can be removed, and noise can be further reduced.
Description
Technical field
The invention belongs to the diesel generator technical field, specially refer to a kind of diesel generator of fixed rotating speed.
Background technique
Diesel generator generally is comprised of diesel engine and generator, and wherein the arbor of the arbor of diesel engine and generator is fixedly connected with, and rotates thereby utilize diesel engine to drive generator, realizes generating.When work, adjust the output power of generator by the rotating speed of regulating diesel engine, but because diesel engine when changing rotating speed, might surpass the speed range of efficient the best, thereby cause generating efficiency to reduce.
Summary of the invention
The objective of the invention is to propose a kind of diesel generator of fixed rotating speed, remain at optimum speed to guarantee diesel engine, and then improve generating efficiency.
The diesel generator of fixed rotating speed of the present invention comprises diesel engine and the generator that is fixed on the base, and key is that this diesel generator also comprises a speed changer; The arbor of described diesel engine is connected with the driving shaft of described speed changer by elastic coupling flexible coupling, and the arbor of described generator is connected with the driven shaft of described speed changer by elastic coupling flexible coupling.
Speed changer can be converted into the rotation of the fixed rotating speed of diesel engine the rotation of the not constant speed of generator, can be the rotating speed of efficiency of energy utilization the best with the speed setting of diesel engine like this, and recently adjust the rotating speed of generator by the speed change that changes speed changer, thereby adjust the output power of generator.In addition, be to be connected with speed changer by elastic coupling flexible coupling respectively because the arbor of diesel engine is connected arbor with generator, elastic coupling flexible coupling can be eliminated most vibration, has further reduced noise.
Further, described diesel engine and generator all by spring supporting on base.When diesel generator was worked, the vibration meeting that diesel engine and generator produce was transmitted on the base by spring, and was absorbed by spring and suppress, and so just can reduce vibration.
Diesel generator of the present invention so that diesel engine can remain at optimum speed, and then improves generating efficiency by speed changer is set, and has good practicability.
