Description
Technical field
The present invention relates to a kind of control system and method for radiation fan of excavator, belong to engineering mechanical device technical field.
Background technique
Traditional excavator radiation fan is by motor Direct driver, the rotating speed of fan changes with the speed change of motor, even if fan can not at maximum (top) speed long-play when needs, when engine speed reduces, corresponding fan speed also reduces, and can not make each parts cooling of excavator timely.Heat radiation for excavator needs, a kind of system and controlling method thereof that automatically can regulate fan work rotating speed according to the temperature signal collected of research and design, the maximum speed of fan can be realized when needed in time, also well engine temperature can be regulated under low engine speed or idling, the each parts of excavator are lowered the temperature timely, normally works significant to keep excavating function.
Summary of the invention
The object of the present invention is to provide a kind of excavator fan control system and method, solve prior art excavator rotation speed of the fan and change with the speed change of motor, effectively can not regulate the technical problem of motor and each part temperatures of excavator.
Object of the present invention is achieved by the following technical programs:
A kind of excavator fan control system, comprise hydraulic oil temperature sensor 1, intercooler temperature transducer 2, cooling-water temperature transmitter 3, controller for excavators 4, motor ECM5, clutch controller 6, rotation speed of the fan sensor 7, fan clutch 8, described hydraulic oil temperature sensor 1 is connected with controller for excavators 4, described intercooler temperature transducer 2, cooling-water temperature transmitter 3 is connected with motor ECM5, described rotation speed of the fan sensor 7 is connected with clutch controller 6, described controller for excavators 4, motor ECM5, communication is carried out by J1939 communications protocol between clutch controller 6, described fan clutch 8 is connected with clutch controller 6.
A kind of excavator fan control system controlling method, comprising:
Gather hydraulic fluid temperature, intercooler temperature, coolant temperature;
When hydraulic fluid temperature T1 be less than 58 DEG C or intercooler temperature T2 be less than 46 DEG C or coolant temperature T3 be less than 80 DEG C time, clutch controller controls fan clutch and is separated;
When hydraulic fluid temperature T1 is 73 DEG C >=T1 >=58 DEG C, or intercooler temperature T2 is when 60 DEG C >=T2 >=46 DEG C, or coolant temperature T3 is when 95 DEG C >=T3 >=80 DEG C, and clutch controller sends SC sigmal control fan clutch and engages, and makes fan low-speed running;
When hydraulic fluid temperature T1 be greater than 73 DEG C or intercooler temperature T2 be greater than 60 DEG C or coolant temperature T3 be greater than 95 DEG C time, clutch controller sends the full-speed operation of SC sigmal control fan;
The fan actual speed gathered and rotating speed of target analysis are contrasted, makes fan actual speed consistent with rotating speed of target.
Compared with prior art, the invention has the beneficial effects as follows: can automatically regulate fan work rotating speed according to the temperature signal that collects, the maximum speed of fan can be realized when needed in time, as at torridity summer, fan is adjustable to maximum speed, gives rapidly motor and miscellaneous part cooling; Winter fan clutch separation or low-speed running, ato unit quick heating, and the consumption that can reduce fan power, energy-saving effect is remarkable, can reduce noise and make motor be operated in optimum temperature region throughout the year, improves service life of aeroengine.
Accompanying drawing explanation
Fig. 1 is system construction drawing of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, excavator fan control system comprises hydraulic oil temperature sensor 1, intercooler temperature transducer 2, cooling-water temperature transmitter 3, controller for excavators 4, motor ECM5, clutch controller 6, rotation speed of the fan sensor 7, fan clutch 8, described hydraulic oil temperature sensor 1 is connected with controller for excavators 4, described intercooler temperature transducer 2, cooling-water temperature transmitter 3 is connected with motor ECM5, described rotation speed of the fan sensor 7 is connected with clutch controller 6, described controller for excavators 4, motor ECM5, communication is carried out by J1939 communications protocol between clutch controller 6, described fan clutch 8 is connected with clutch controller 6.
Described controller for excavators 4, motor ECM5 are mainly used to gather hydraulic fluid temperature, intercooler temperature, coolant temperature, be analyzed and send a signal to clutch controller 6 by J1939 communications protocol to temperature.
Described clutch controller 6 receives temperature signal, and gathers the tach signal of rotation speed of the fan sensor 7, by tach signal and target signal comparative analysis, controls fan clutch and reaches the object controlling rotation speed of the fan.
When controller for excavators and motor ECM collect hydraulic fluid temperature T1 be less than 58 DEG C or intercooler temperature T2 be less than 46 DEG C or coolant temperature T3 be less than 80 DEG C time, clutch controller controls fan clutch and is separated, rotation speed of the fan slows down, substantially be idle running, make motor energy rapid temperature increases when ambient temperature is low; When hydraulic fluid temperature T1 is 73 DEG C >=T1 >=58 DEG C, or intercooler temperature T2 is when 60 DEG C >=T2 >=46 DEG C, or coolant temperature T3 is when 95 DEG C >=T3 >=80 DEG C, and clutch controller sends SC sigmal control fan clutch and engages, make fan low-speed running, to engine radiating; When hydraulic fluid temperature T1 be greater than 73 DEG C or intercooler temperature T2 be greater than 60 DEG C or coolant temperature T3 be greater than 95 DEG C time, clutch controller controls fan full-speed operation, plays the effect regulating engine temperature.Clutch controller gathers the actual speed of fan by rotation speed of the fan sensor and rotating speed of target analysis contrasts, and fan control clutch makes fan actual speed consistent with rotating speed of target.Three each operating temperature points of temperature transducer and corresponding rotating speed according to the actual conditions of motor, can be set by program.
In addition to the implementation, the present invention can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
