Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, the utility model provides a pair of diesel generating set, including base 5, the middle part above the base 5 is equipped with diesel engine 4, 4 left sides of diesel engine are equipped with heat dissipation water tank 2, 4 right sides of diesel engine are connected with generator 7, 7 right sides of generator are equipped with opens and stops control box 11, diesel engine 4 with connect through reduction gear 6 between the generator 7.
This technical scheme adopts between diesel engine 4 and generator 7 through reduction gear 6, can increase the moment of torsion through reduction gear 6, can drive more powerful generator 7 electricity generation through the same 4 outputs of diesel engine, can reduce the volume of complete machine like this, and convenient equipment and transport can reduce diesel engine 4's purchase expense, reduction in production cost to improve diesel generating set's performance.
The excitation rotor of the original motor is 4 poles; the existing motor excitation rotor is 8 poles, the rotating speed of the diesel engine 4 is 1500 rpm, the rotating speed of the generator 7 is 750 rpm, and the torque ratio of the generator 7 to the diesel engine 4 after the reducer 6 is adopted is 0.6 to 1, so that compared with the prior technical scheme, the energy is saved, the emission is reduced, and 30-40% of diesel oil can be saved.
According to the technical scheme, the speed reducer 6 is additionally arranged, the speed ratio of the speed reducer 6 is 2:1, namely the torque ratio is 0.5 to 1, the torque is doubled, but the loss of the speed reducer is 5%. To compensate for the torque loss, the input torque of the reducer is calculated as: then the actual retarder torque ratio, including the torque loss value, is 0.525 to 1. In order to improve the safety factor of the diesel generator set, the torque ratio is adjusted to be 0.6 to 1. For example, a 100kW generator: the prior art needs to configure a 110kW diesel engine 4 to be matched with a 100kW generator 7. However, the speed ratio of the speed reducer 6 is 2: in the case of 1, a torque ratio of 0.6 to 1 taking into account the safety factor is required to assemble a 100kW generator 7 with only a 66kW diesel engine 4.
According to the technical scheme, the output torque of the diesel engine 4 is increased by adopting the speed reducer 6, the cost of the speed reducer 6 is much lower than that of the diesel engine 4 which is directly replaced, the whole engine occupies a small installation space, the assembly is more convenient, the oil is saved, the emission is reduced by 30% -40%, the transportation is more convenient, the cost is lower, and the diesel engine is suitable for being used in a small space, so that the diesel generator set has better advantages.
The reducer 6 is sleeved with a reducer shield 10. Therefore, the speed reducer 6 can be protected, and the speed reducer 6 is prevented from being damaged due to external impact.
