Description
Technical Field
The invention relates to equipment for regulating and controlling the rotating speed of an engine, in particular to a simulation test platform and a simulation test method for an electronic rotating speed controller.
Background
As is well known, the torque of a diesel engine does not change greatly with the rotating speed, and the torque/rotating speed curve is relatively smooth, so that the power/rotating speed curve is in an overall linear rising form, unlike the torque of a gasoline engine which changes greatly with the rotating speed; therefore, the rotating speed is the most real-time and most intuitive and effective data reflecting the working condition of the diesel engine. Meanwhile, when the throttle of the diesel engine is regulated, a certain time delay exists between the rotating speed of the diesel engine reaching the target rotating speed and the throttle regulating instruction.
When the engine is matched with the generator, the rotating speed of the engine matched with the generator must be stable and adjustable because the frequency of electricity generated by the generator is directly related to the rotating speed of the engine. After loading and unloading the throttle, a new stable state is required.
The conventional generator set which generates electricity by using a diesel engine adopts two rotation speed adjusting modes except for the electric spray engine, namely a pure mechanical speed adjusting mode and an electronic speed adjusting actuator mode, wherein the electronic speed adjusting actuator mode is superior to the pure mechanical speed adjusting mode in the aspects of adjusting precision, failure rate and service life.
However, the electronic speed regulation actuator product works on the principle that direct current is conducted through a coil, a torque generated by an inclined port end of an armature iron is balanced with spring force to drive a rotor to rotate, and the oil quantity is adjusted by adjusting the size of an oil hole, so that the rotor rotates in a reciprocating mode all the time when working, the rotor cannot effectively adjust the oil quantity to adjust the rotating speed due to the fact that abrasion of the rotor is easily caused by impurities and the like, and therefore a test simulation test needs to be conducted on the rotor in the production process so as to detect various performances of the rotor.
