Description
Technical field
The present invention relates to a kind of land leveller ultralow temperature and start system.
Background technology
The area such as Northeast China and Russia, generally removes the snow with land leveller, opens ice winter.And the frequent energy of these region temperatures
Drop to subzero less than 40 degrees Celsius, especially after land leveller outdoor storage, start more when its internal temperature is identical with ambient temperature
Adding difficulty, land leveller adaptability under severe cold environment is had higher requirement by this.
Common engine low-temperature cold starting is to heat auxiliary starting system, boiler heating at engine intake, start
Time air inlet spray ether, be simultaneously connected with external power supply and start.
The heating of driver's cabin is typically chosen use warm-air drier, but the thermal source of warm-air drier heating is usually cycle of engine
Water, when ambient temperature is at subzero less than 40 degrees Celsius, and engine coolant water temperature is on the low side so that warm-air drier heating weak effect, drives
Sail handling comfort to decline.
The difficult reason mainly having three aspects of land leveller cold-starting:
(a) when ambient temperature is at subzero less than 40 degrees Celsius, and Engine Inlet Temperature is correspondingly low 20-60 DEG C than under room temperature, because of
Air themperature when compression ends in this cylinder is the lowest 20-60 DEG C, and it is required not reach during engine start
Ignition temperature.
B, during () low temperature, engine oil viscosity strengthens, the resistance between each friction pair strengthens so that under engine start rotating speed
Fall, adds the consumption starting power.Further, since low temperature causes part fit clearance to reduce, relative motion can be damaged by force
Part, reduces the service life of equipment.
C () declines the most accordingly along with the reduction of ambient temperature, the fan-out capability of accumulator.At subzero 40 degrees Celsius of low temperature
In the case of, the fan-out capability of accumulator can only achieve about the 30% of specified fan-out capability.Therefore, result in engine start system
System power drop so that the rotating speed that starts of electromotor is less than required minimum speed, causes engine start difficulty maybe cannot open
Dynamic.
Summary of the invention
For three subject matters of above-mentioned cold-starting difficulty, the present invention provides a kind of land leveller ultralow temperature to start system
System, can preheat accumulator, engine coolant, engine oil the most in advance, not use external electricity
Make land leveller start in ultra-low temperature surroundings in the case of source, solve at cold district and without the startup in the case of external power supply
Problem.
The technical solution used in the present invention is:
A kind of land leveller ultralow temperature starts system, it is characterised in that: include electromagnetic pump, the accumulator heating controlled by controller

Internal body circulation, to engine body heat.
Also include a warm-air drier being connected with cold start-up heater；On the pipeline that cold start-up heater is connected with warm-air drier
The one electromagnetism shunt valve being controlled keying by controller is set；When electromagnetism shunt valve is opened, make cold start-up heater with warm-air drier even
Logical, through coolant entrance warm-air drier inner loop while entering electromotor of described cold start-up heater heating, to warm braw
Machine heats.
Described battery heater is an independent heating system, is fixed on the afterbody of the afer bay of land leveller, passes through
Fuel pipe is connected with electromagnetic pump.
Described battery heater makes the air of heating at accumulator peripheral circulation by blower fan, heats accumulator.
Described cold start-up heater makes coolant circulate, to electromotor at the internal body of electromotor by water circulating pump
Body heats.
Described cold start-up heater water inlet by electromagnetism shunt valve respectively with warm-air drier outlet pipe and engine water outlet
Pipe connects, and outlet is connected with warm-air drier and water inflow of the engine pipe by three way cock's water inlet pipe.
Controller startup work is made to the power supply of controller by accumulator.
The invention has the beneficial effects as follows:
The most in advance accumulator, engine coolant, engine oil are preheated, the most extensive
The fan-out capability of multiple accumulator, improves the temperature of engine block, makes the dynamical system of land leveller be rapidly achieved the bar being suitable for operation
Part；Make land leveller start in ultra-low temperature surroundings in the case of not using external power supply, solve land leveller cold district with
And without the starting problem in the case of external power supply, avoid the abrasion that low-temperature cool starting brings to electromotor simultaneously.Meanwhile, improve
Warm-air drier heating effect, makes the comfortableness of riding manipulation be greatly improved.
