The controller is used for acquiring, operating and analyzing external operating parameters of the excavator, and then outputting a PWM (Pulse Width Modulation) control signal, so that dynamic control on the running speed of the silicone oil fan is realized, and the purposes of reducing the power consumption of the fan, reducing the oil consumption and reducing the noise are achieved while the requirement of cooling of the whole vehicle is met.
Description
Technical field the utility model belongs to technical field of engineering machinery, is specifically related to a kind of excavator silicon-oil fan control device.
Background technology for a long time, the excavator cooling fan mostly adopts and is rigidly connected, speed of cooling fan is followed the running speed of motor, can not realize independent control.In the practical operation; When externally environment temperature is low; Motor has not needed too big heat dissipation capacity; Even the thermostat of engine interior cuts out the water route of cooling water tank, and the cooling fan of radiator of water tank is still followed the engine speed running, so just causes unnecessary power consumption.Along with rising steadily of oil price, excavator running cost constantly increases; How to reduce oil consumption, energy conservation and become the design new approaches that each producer keeps reforming innovation, simultaneously, in today that environment goes from bad to worse, energy-saving and emission-reduction are our responsibility that can not be ignored especially.
The purpose of summary of the invention the utility model is to solve prior art to have the high technical problem of energy consumption, a kind of excavator silicon-oil fan control device is provided, to overcome the deficiency of prior art.
The utility model excavator silicon-oil fan control device, it comprises that Information Monitoring and the controller that sends instruction, executive component electronic silicone oil fan reach engine air inlet temperature sensor, engine water temperature sensor and the hydraulic fluid temperature sensor that engine temperature is detected; Said engine air inlet temperature sensor, engine water temperature sensor and hydraulic fluid temperature sensor are communicated with controller through data wire; Speed probe that detects the current rotating speed of cooling fan and the electromagnetic clutch of carrying out the rotating speed adjustment are installed on the said electronic silicone oil fan; Controller is communicated with electromagnetic clutch through DOL Data Output Line, is communicated with speed probe through Data In-Line.
Establish the CPU module in the said controller, be communicated with memory module, power module, fan speed-regulating module and communication module through holding wire respectively.
The utility model excavator silicon-oil fan revolution speed control device; Through controller to the outside operational factor of excavator gather, operational analysis; The output pwm control signal; Realized dynamic control, under the prerequisite that satisfies the car load radiating requirements, realized the purpose of fan power consumption reduction, reduction oil consumption and minimizing noise the silicon-oil fan running speed.
Description of drawings Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model module diagram.
Among the figure 1, engine water temperature sensor 2, hydraulic fluid temperature sensor 3, controller 4, electronic silicone oil fan 5, engine air inlet temperature sensor 6, memory module 7, power module 8, CPU module 9, fan speed-regulating module 10, communication module
The specific embodiment is according to Fig. 1 and Fig. 2, and it comprises that Information Monitoring and the controller 3 that sends instruction, executive component electronic silicone oil fan 4 reach engine air inlet temperature sensor 5, engine water temperature sensor 1 and the hydraulic fluid temperature sensor 2 that engine temperature is detected the utility model; Said engine air inlet temperature sensor 5, engine water temperature sensor 1 and hydraulic fluid temperature sensor 2 are communicated with controller 3 through data wire; Speed probe that detects the current rotating speed of cooling fan and the electromagnetic clutch of carrying out the rotating speed adjustment are installed on the said electronic silicone oil fan 4; Controller 3 is communicated with electromagnetic clutch through DOL Data Output Line, is communicated with speed probe through Data In-Line; Establish CPU module 8 in the said controller, be communicated with memory module 6, power module 7, fan speed-regulating module 9 and communication module 10 through holding wire respectively.
The effect of the utility model critical piece and operating principle controller 3 are transfer of data, collection and processing unit, are responsible for the external data of excavator running environment is carried out collection analysis and electronic silicone oil fan 4 is carried out the control of real-time motion; Temperature pick up comprises the temperature pick up of detection of engine water temperature, the temperature pick up that detects hydraulic fluid temperature and the temperature pick up of detection of engine intake air temperature, the detection of each monitoring point temperature when accomplishing the excavator operation; Its inside of electronic silicone oil fan is equipped with speed probe that detects cooling fan rotation speed and the electromagnetic clutch that carries out fan start and stop and rotational speed regulation.Controller 3 receives the data of temperature pick ups transmission and also analyzes, judge silicon-oil fan whether need start working with and rotating speed big or small; The effect of temperature pick up is the intake air temperature of detection of engine water temperature, hydraulic fluid temperature and motor.The tach signal that the speed probe that controller is installed according to the data and the electronic silicone oil fan inside of the water temperature sensor, hydraulic fluid temperature sensor and the engine air inlet temperature sensor that receive provides; Confirm the target running speed of silicon-oil fan; The electromagnetic clutch of output pwm control signal to electronic silicone oil fan is regulated cooling silicon-oil fan rotating speed and is made it in desirable rotation speed operation.
The utility model has solved for a long time the excavator cooling fan and has followed engine running; The drawback of the meaningless energy loss that causes; The external condition (water temperature, hydraulic oil temperature, intake air temperature) of utilizing intelligent controller to detect excavator running environment is dynamically controlled the silicon-oil fan running speed, and the operational situation that makes speed of cooling fan follow excavator is carried out Real-time and Dynamic and regulated.The P=KV that concerns according to power and rotating speed
3(P is that power, the V of fan consumption is engine speed) is when the low perhaps engine loading of ambient temperature is light; Controller is in time regulated the rotating speed of cooling fan of engine; The running speed of reduction or shutting engine down fan has so just reduced the consumption of fan running to engine power.Promote the rotating speed of cooling fan of engine when higher or engine loading is heavier when ambient temperature timely.So just realized the purpose that motor is worked under the stationary temperature environment.Consumption having guaranteed to effectively reduce when excavator runs well cooling fan of engine power has reached the purpose that reduces fuel consume, energy conservation, protection environment.
