A pipeline covers parts, needing to be cooled, of a diesel; the pipeline covering different parts, needing to be cooled, of the diesel define a circulating loop; an electronic control pressure pump is connected in the circulating loop; and the electronic control pressure pump is independent of the diesel to drive cooling water in the circulating loop to circulate. The diesel cooling system can control cooling water individually, and temperature rise of the diesel cooling system is easily controlled.
Description
Technical field
The present invention relates to field of cooling, particularly a kind of diesel engine cooling system.
Background technique
Existing diesel cooling system almost all adopts cooling water circulation cooling, and water inlet and outlet temperature maintains between 80-95 DEG C, and cooling water is in non-boiling state.This system mainly contains water pump, machine oil cooler (cooling machine oil), air compressor, pressurized machine, cylinder block (or cylinder liner), cylinder head, thermostat, radiator, water tank and connecting pipeline etc. by the component of cooling water circulation.Wherein water pump is circulation power source, thermostat controls large and small cycles, cooling water brings heat to distribute from machine oil cooler (cooling machine oil), air compressor, pressurized machine, cylinder block (or cylinder liner), cylinder head by radiator, maintains system temperature and stablizes.
But existing diesel cooling system has following several shortcoming:
1) low temperature environment heats up slow, and wayward.Existing cooling system water pump is with motor start and stop, and namely cooling water cannot control separately, always with starting operation to be in circulation, heats up slow during low temperature;
2) seal request high, easily produce corrosion.Existing cooling system is high to the seal request such as cylinder liner, cylinder block and cylinder cover, and cooling water directly flows through casting water cavity and easily produces corrosion;
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of diesel engine cooling system, can control separately cooling water, heat up easy to control.
For achieving the above object, the invention provides a kind of diesel engine cooling system, the position of cooling is needed to cover pipeline at diesel engine, be covered in the pipeline composition circulation loop at diesel engine difference cooling position, be connected to automatically controlled compression pump in circulation loop, this automatically controlled compression pump drives the cooling water circulation in circulation loop independent of diesel engine.
Preferably, diesel engine needs the position of cooling to comprise cylinder sleeve and cylinder cap.
Preferably, the pipeline on cylinder sleeve is around the outer wall of cylinder sleeve.
Preferably, the pipeline be looped around on cylinder sleeve comprises 1 to 3 group around unit, and often group is around cell rings around the some circles of cylinder sleeve, all merges into house steward around the intake pipe of unit and outlet pipe.
Preferably, what the pipeline on cylinder cap bent is built in the entity part of cylinder cap.
Preferably, condenser is accessed in circulation loop.
Preferably, the downstream of condenser is connected to liquid container, and this liquid container is used for storing liquid cooling water, and liquid cooled water continues circulation by automatically controlled compression pump.
Preferably, radiator and recycle pump is connected in the outer circulation loop of condenser.
Compared with prior art, the present invention has following beneficial effect: by designing a kind of type of cooling cooling cooling line coverage goal part, compression pump adopts electric drive, the intensification avoiding traditional cooling system is slow, seal request is high, the shortcoming of water cavity easy-to-rust, the power source no longer direct correlation engine operation condition of pump, can independently control.
