Description
Technical field
The present invention relates to a kind of oil circuit to lead to self compensating system, and particularly a kind of oil way of diesel vehicle leads to self compensating system.
Background technology
At present in the winter in severe cold areas and the north, when temperature arrives subzero 50 DEG C below 0 DEG C, the bavin in diesel vehicle
Oil meeting wax knot, diesel vehicle usually can not start, bring difficulty to these regional cargo transports and production, influence people's
Normal life.And the oil circuit aging and breakage for diesel vehicle can not check in time, typically according to the public affairs of diesel vehicle traveling
Mileage is come the oil circuit material more renewed, and when often changing, oil circuit material can also use.Either also not to replacing when
Wait, damaged oil leak or blocking, people can not but have found oil circuit material in time, it is impossible to change the damaged material of oil circuit in time
Material, it is impossible to dredged in time to the oil circuit of blocking, hidden danger is caused to the life security of people, is also one to the diesel oil energy
Kind wastes.
The content of the invention
The technical problem to be solved in the present invention is：A kind of oil way of diesel vehicle is provided and leads to self compensating system, diesel vehicle is existed
The winter in severe cold areas and the north easily starts traveling, can easily and timely detect whether oil circuit is normal, and elimination is safe in time
Hidden danger, save the energy.
The present invention the content of the invention be：It is by diesel oil tank, pressure-oil tank, oil water separator, diesel fuel filter, high pressure
Diesel pump, engine, gas receiver, the part of air pressure automatic compensator eight composition, wherein diesel oil tank is connected with pressure-oil tank, high pressure
Fuel tank is connected with oil water separator, and oil water separator is connected with diesel fuel filter, and diesel fuel filter is connected with fuel pump, high
Pressure diesel pump is connected with engine, and engine is connected with gas receiver, and gas receiver is connected with air pressure automatic compensator, gas receiver and gas
Gases at high pressure one-way control valve is housed between pressure automatic compensator；On pressure-oil tank check valve, air pressure are imported equipped with gases at high pressure
Automatic compensator imports check valve by gases at high pressure and is connected with pressure-oil tank；Fluid valve, high pressure bavin are housed on pressure-oil tank
Oil pump is connected by fluid valve with pressure-oil tank；One-way fluid flow valve is housed, pressure-oil tank passes through one-way fluid flow valve on pressure-oil tank
It is connected with diesel oil tank；Autocontrol valve is housed on pressure-oil tank, autocontrol valve mounted in diesel oil tank and oil water separator it
Between on the pipeline that is connected, while be connected with pressure-oil tank, diesel oil tank with oil water separator；Autocontrol valve includes automatically controlled control
Valve and gas processed compensate two parts automatically；Automatically controlled control valve is connected with temperature sensor and the time relay respectively.
When temperature is below 5 DEG C, automatically controlled control valve is in normally open；
When temperature is more than 5 DEG C, automatically controlled control valve is in normally off.
In use, when temperature arrives subzero 50 DEG C below 0 DEG C, the diesel oil in diesel vehicle usually can wax knot.At this moment start
Autocontrol valve, the automatically controlled control valve of autocontrol valve start that normally open, hydraulic oil is presented by the temperature sensor of connection
Case provides high-pressure diesel to fuel pump, and high-pressure diesel makes the oil inlet of fuel pump have 2.0MPa oil pressure all the time, protects
Card meets oil mass, and diesel engine is started working.During vehicle launch, there is no gases at high pressure in pressure-oil tank, autocontrol valve starts 5 points
Below clock during the time, air pressure automatic compensator is to gases at high pressure are imported in pressure-oil tank, when the gases at high pressure pressure in pressure-oil tank
By force in 0.6MPa--0.9MPa, compensation closes automatically controlled control valve to the gas in pressure-oil tank automatically, now autocontrol valve
Close.At this moment vehicle has been warmed up, and the diesel oil of wax knot starts to melt in diesel oil tank, and diesel oil tank passes through oil water separator, bavin
The diesel oil that oil strainer normal supply fuel pump melts.
Check valve, one-way fluid flow valve are imported equipped with gases at high pressure on pressure-oil tank, when the hydraulic oil in pressure-oil tank is too many
When, the hydraulic oil in pressure-oil tank is transferred to diesel oil tank by one-way fluid flow valve；Gases at high pressure import check valve gases at high pressure from
Air pressure automatic compensator imports pressure-oil tank.
Under normal working of engine, the high-pressure diesel of fuel pump some entered by high pressure oil return line and fluid valve
Enter pressure-oil tank, the high-pressure diesel of pressure-oil tank is reached 2.0MPa oil pressure, and keep 2.0MPa forever, when oil pressure is higher than
During 2.0MPa, the high-pressure diesel of pressure-oil tank is returned in diesel oil tank by one-way fluid flow valve.
Ordinary circumstance, start diesel engine, using the time relay being connected with automatically controlled control valve, open autocontrol valve 5
The time of minute, the change for the hydraulic oil that observation pressure-oil tank is flowed into fuel pump can be seen that oil water separator and diesel oil
Whether the oil circuit of filter blocks or breakage, then opens oil water separator and diesel fuel filter device respectively, by checking,
Pair determine that the oil water separator of aging or breakage and the oil circuit of diesel fuel filter are updated, without what is advanced according to diesel vehicle
Milimeter number is regularly updated, and has been saved oil circuit material, has been eliminated potential safety hazard, has saved diesel fuel.
Advantages of the present invention：1. northerly winter and severe cold areas can start diesel vehicle at any time, to people's
Life will not impact；2. it can check whether oil water separator blocks with diesel fuel filter oil circuit, oil leak at any time, can be in time
The oil circuit of aging and oil leak is updated, is regularly updated, eliminated without the milimeter number advanced according to diesel vehicle
Potential safety hazard, oil circuit material is saved, has saved the energy.
