Description
Technical field
The present invention relates to a kind of land leveller ultralow temperature activation systems.
Background technique
The areas such as Northeast China and Russia, winter is usually with land leveller snow removing, ice-breaking.And the frequent energy of these region temperatures
Subzero 40 degrees Celsius are dropped to hereinafter, starting more when internal temperature is identical as environment temperature especially after land leveller outdoor storage
Add difficulty, more stringent requirements are proposed to adaptability of the land leveller under severe cold environment for this.
Common engine low-temperature cold starting is to heat auxiliary starting system, boiler heating, starting in engine intake
When air inlet spray ether, while connecting external power supply and being started.
The heating of driver's cabin is typically chosen using warm-air drier, but the heat source of warm-air drier heating is usually cycle of engine
Water, when environment temperature at subzero 40 degrees Celsius hereinafter, engine coolant water temperature is relatively low so that warm-air drier heating effect is poor, drive
Sail handling comfort decline.
There are three land leveller cold-starting difficulty is main the reason of aspect:
(a) when environment temperature at subzero 40 degrees Celsius hereinafter, Engine Inlet Temperature is correspondingly than 20-60 low under room temperature
DEG C, therefore the air themperature in cylinder when compression end of a period equally also wants low 20-60 DEG C, it must when engine start is not achieved
The ignition temperature needed.
(b) when low temperature, engine oil viscosity is increased, and the resistance between each friction pair increases, so that under engine start revolving speed
Drop, increases the consumption of startup power.In addition, relative motion can damage by force since low temperature causes part fit clearance to reduce
Part reduces the service life of equipment.
(c) with the reduction of environment temperature, the fan-out capability of battery also accordingly declines.In subzero 40 degrees Celsius of low temperature
In the case of, the fan-out capability of battery can only achieve 30% or so of rated output ability.Therefore, engine start system is resulted in
Power decline of uniting causes engine start difficult or can not open so that the starting revolving speed of engine is lower than required minimum speed
It is dynamic.
Summary of the invention
For three main problems of above-mentioned cold-starting difficulty, the present invention provides a kind of ultralow startup temperature system of land leveller
System, can before an engine is started in advance preheat battery, engine coolant, engine oil, not use external electricity
Start land leveller in ultra-low temperature surroundings in the case of source, solves in cold district and starting in the case where without external power supply
Problem.
The technical solution adopted by the present invention is that:
A kind of land leveller ultralow temperature activation system, it is characterised in that: including electromagnetic pump, the battery controlled by controller
Heater and cold start-up heater；
Fuel oil, supply battery heater and cold start-up heating is sucked out in the controller control electromagnetic pump from fuel tank
Device；
The battery heater heats battery by non-combusted fuels；
Meanwhile the cold start-up heater heats coolant liquid by non-combusted fuels, and by sending out coolant liquid
The internal body of motivation recycles, and heats to engine body.
It further include a warm-air drier being connect with cold start-up heater；On the pipeline that cold start-up heater is connect with warm-air drier
The one electromagnetism shunt valve opened and closed by controller control is set；When electromagnetism shunt valve is opened, makes to be cold-started heater and warm-air drier connects
Logical, the coolant liquid through the cold start-up heater heating enters inside warm-air drier while entering engine to be recycled, to warm wind
Machine heating.
The battery heater is an independent heating system, is fixed on the tail portion of the rear frame of land leveller, passes through
Fuel pipe is connect with electromagnetic pump.
The battery heater makes the air of heating in battery peripheral circulation by blower, heats to battery.
The cold start-up heater recycles coolant liquid in the internal body of engine by water circulating pump, to engine
Body heating.
The cold start-up heater water inlet by electromagnetism shunt valve respectively with warm-air drier outlet pipe and engine water outlet
Pipe connection, water outlet are connect by three-way connection water inlet pipe with warm-air drier and water inflow of the engine pipe.
Controller is set to start work to the power supply of controller by battery.
The beneficial effects of the present invention are:
Battery, engine coolant, engine oil are preheated in advance before an engine is started, in the very short time
The interior fan-out capability for restoring battery, improves the temperature of engine block, the dynamical system of land leveller is made to be rapidly achieved suitable operation
Condition；Start land leveller in ultra-low temperature surroundings when not using external power supply, solves land leveller on cold ground
Area and without external power supply in the case where starting problem, while avoid low-temperature cool starting give engine bring abrasion.Meanwhile
Warm-air drier heating effect is improved, the comfort of riding manipulation is greatly improved.
