Description
Technical field
The utility model relates to engine blower control field, especially a kind of fan coolling automatic control system.
Background technique
Fan is used to control the temperature of engine water temperature, motor intake manifold temperature and hydraulic oil simultaneously, and bull-dozer is made
Industry operating condition is severe, and in cold winter or under extremely cold environment, when system oil temperature is lower than set temperature, temperature-controlled fan can not but stop
Only still engine and hydraulic oil are cooled down in air-supply, hydraulic oil is caused to delay to be warming up to reasonable working temperature section
It is interior, while causing the waste of the energy.
But conventional temperature control fan cannot achieve the stalling of fan under engine operating status at present, and fan positive and negative rotation is cut
It changes after must stopping engine operating and carries out.
When engine operation, temperature is too low, and that flammable mixed steam can be made to light difficult or burning is slow, causes engine power
Decline, machine oil thickens because temperature is too low, and viscosity increases, and increases the resistance of train motion, because of temperature is too low incomplete vapour
The fuel of change washes away the oil film on the friction surfaces such as steam-cylinder piston, piston ring and aggravates component wear to oil dilution or make to mix
It closes vapour incomplete combustion and increases fuel consumption, seriously affect the operational efficiency of engine.

Function.
Fan coolling automatic control system is in cold winter or extremely under cold environment: coolant liquid or hydraulic oil do not rise
When needing to start engine to ideal temperature, the hydraulic oil of hydraulic pump output direct oil return box without temperature-controlled fan motor；
In this case hydraulic pump is because without load power consumption is lower.Engine under cold environment, is born in cold winter or extremely
Load is smaller to be easier to start.
In cold winter or under extremely cold environment, even if engine start, but coolant liquid or hydraulic oil not on
It is raised to ideal temperature, temperature-controlled fan motor still stops operating, therefore more energy saving.There is no temperature-controlled fan to force cooling, starts
Machine temperature is promoted just faster；Engine more easily reachs ideal operating temperature.And since temperature-controlled fan motor stops operating,
The temperature loss of hydraulic oil is smaller, is also beneficial to the raising of hydraulic fluid temperature.
Fan coolling automatic control system in cold winter or extremely under cold environment, when coolant liquid or hydraulic oil not on
When being raised to ideal temperature, the energy consumption almost all of hydraulic pump is converted into the interior energy of hydraulic oil.It is equivalent to and is increased to hydraulic oil container
One assisted heating device, hydraulic oil can faster be warming up to ideal temperature.Therefore bull-dozer can more efficiently put into production
Work.
