Example 1
As shown in fig. 1, to solve the problem that when the pilot control pressure is high in the prior art, even though the electric loader pump does not need to output a large flow, the electric loader pump still outputs a large flow to cause energy loss, the embodiment provides an energy saving and consumption reduction control system for an electric loader, including: main pump 2 and hydro-cylinder 4 still include travel switch 5 and controller 6, travel switch 5 sets up on hydro-cylinder 4, main pump 2, hydro-cylinder 4 and travel switch 5 all with 6 control connection of controller, travel switch 5 is used for detecting the stroke of hydro-cylinder 4, controller 6 is used for controlling the rotational speed of main pump 2 according to travel switch 5's testing result.
More specifically, in the present embodiment, the oil cylinder 4 is powered by the oil tank 1, and in addition, in order to facilitate the travel switch 5 to be able to detect the travel of the oil cylinder 4, in the present embodiment, the travel switch 5 is fixedly connected to the piston rod of the oil cylinder 4, so that the travel switch 5 and the piston rod of the oil cylinder 4 can move synchronously, and the travel of the oil cylinder 4 is detected in real time.
More specifically, the present embodiment further comprises a motor 7, an output shaft of the motor 7 is connected with an input shaft of the main pump 2 through a coupling, and the motor 7 is used for providing power for the operation of the main pump 2.
More specifically, the present embodiment further includes a flow control valve 3, where the flow control valve 3 is disposed on a working circuit of the main pump 2 and connected to the controller 6, and the flow control valve 3 is configured to control an output flow of the main pump 2.
In the embodiment, the stroke switch 5 is arranged on the working oil cylinder 4 of the loader to test the stroke of the oil cylinder 4, when the stroke of the oil cylinder 4 reaches the maximum value, the oil cylinder 4 is indicated to reach the end point, and the controller 6 controls the flow control valve 3 to reduce the output flow of the main pump 2, so that the effects of saving energy and reducing consumption are achieved.
Example 2
Substantially the same as in example 1. Except that the present embodiment further defines a method by which the controller 6 controls the rotational speed of the main pump 2 based on the detection result of the stroke switch 5. In this embodiment, the controller 6 is configured to control the rotation speed of the main pump 2 according to the detection result of the travel switch 5, and includes:

Specifically, in this embodiment, the rotation speed of the motor 7 may be controlled to decrease with time at a rate of 10% within the preset amplitude until the rotation speed of the motor 7 reaches the minimum value required by the preset amplitude. Because the main pump 2 is connected with the motor 7, when the rotating speed of the motor 7 is reduced, the rotating speed of the main pump 2 is reduced, and therefore the effects of energy conservation and consumption reduction can be achieved.
