Abstract
The proposal is for a process for regulating the cooling system of an especially powerful diesel-engined excavator drive, where a thermostat (4) fitted in the region of the diesel engine (1) opens the flow path of the diesel engine (1) to a radiator (5) co-operating with a fan (8) at a predetermined water temperature, in which a temperature measuring device (11) fitted in the region of the flow path controls the fan (8) in such a way that, within a predeterminable temperature range above the thermostatically controlled water temperature, the rotation speed of the fan (8) is regulated in the range between 0 min<-1> and a maximum speed.
Description
The present invention relates to a kind of method that is used for regulating superpower diesel engine excavator cooling system for drives.
Usually excavator is at least by a Diesel Driven, and wherein it usually also is used for driving the fan of water cooler.Have such possibility as a kind of selection scheme: fan is handled by independent fluid pressure drive device, and wherein oil hydraulic pump is equally by Diesel Driven.Therefore fan ceaselessly rotates along with at that time diesel engine speed, wherein the superpower diesel engine (＞when 600KW) driving excavator, power loss reaches 5%.According to the difference of excavator specification size here power loss roughly may reach 55 to 60KW.Same also have a shortcoming to be: because the difference that fan ceaselessly and then rotates along with rotating speed produces the noise of can not ignore.
The purpose of object of the present invention is: design a kind of be used for the regulating method of superpower diesel engine excavator cooling system for drives and the cooling system of superpower diesel engine excavator drive unit, can avoid power loss on the one hand with it, reduce noise level on the other hand.
This purpose reaches with such method in a kind of method that is used for regulating superpower diesel engine excavator cooling system for drives: thermostat (Thermostat) that is contained on the diesel engine position is opened the passage from diesel engine to the water cooler that concurs with fan when a water temperature given in advance, the temperature measuring equipment that wherein is contained in the passage area is controlled fan like this, regulates in the scope of rotating speed between 0 to maximum (top) speed of a temperature range internal fan that can predeterminedly surpass the water temperature that thermostat regulates.
Good concrete structure by the inventive method can obtain from dependent claims.
This purpose also reaches by a cooling system that is used for superpower diesel engine excavator drive unit, the connecting tube or the flexible pipe of cooling medium between the fan of the diesel engine that it is regulated with a thermostat, a water cooler, a single driving and diesel engine and the water cooler, wherein be provided with a temperature measuring equipment in the zone of coolant guiding channel, it links to each other with fan drive device by signaling line.
Good concrete structure by cooling system of the present invention can obtain from dependent claims.
By reaching by standard of the present invention, only fan just starts when needing cool air really.Compare with the method for operation up to now especially in drive unit consumed up to now about 5% the power loss of cold area saving by fan or it.By rise now fan only when needed or in the low-speed range rotation reduced the noise that produces by whole drive unit.
An embodiment by means of expression in the drawings does following elaboration to content of the present invention.
Unique accompanying drawing is as further the do not draw Diesel Driven device of the hydraulic excavator digger that comes of principle schematic representation.Can see a diesel engine 1, one chilled(cooling) water return (CWR), inside 2, a water pump 3 and thermostat 4 in diesel engine 1.Flow along its inner passage by means of water pump 3 cooling mediums, up to arriving a temperature given in advance, for example till 85 ℃ always.Thermostat 4 is designed to like this: it opens and is opened to the passage of back water receiving cooler 5 when arriving this temperature.Diesel engine 1 links to each other with water cooler 5 by pipeline 6,7, makes the passage of cooling medium no longer only comprise home loop 2, but also comprises pipeline 6,7 and water cooler 5.In water cooler 5 back a fan 8 is housed, it drives by the hydraulic system of being made up of fan oil pump 9 (L ü fterpumpe) and oil hydraulic motor 10 in described embodiment.Part at pipeline 6 is equipped with a temperature measuring equipment 11, it by electrical signal line 12 with only marked regulator 13 here and linked to each other, it makes the fan oil pump 9 as variable displacement pump in described embodiment.Fan oil pump 9 is driven by diesel engine 1, and hydraulic medium is delivered to the oil hydraulic motor 10 that links to each other with fan, and it is a fixed displacement motor (Konstantmotor) in this embodiment.Regulate cooling system like this, not by motor 10 drive fan 8, just this fan does not change before the water temperature (for example 87 ℃) that arrives a regulation.Thermostat 4 is opened after water temperature arrives 85 ℃, and opens the passage that cooling medium leads to water cooler 5.Only continue to raise (up to 87 ℃ in water temperature, it is recorded by temperature measuring equipment 11) time handle the regulator 13 of fan oil pumps 9 by signaling line 12, make its revolution, this moment, hydraulic medium was delivered to fan motor, it slowly raises since 0 rotating speed then, and rotating speed is to the highest when 95 ℃ of left and right sides water temperatures.Therefore set up one 8 ℃ temperature window, regulate in the maximum (top) speed scope of regulation 0 at this temperature range internal fan rotating speed.Above-mentioned steps is carried out with opposite order when water temperature reduces, and that is to say, rotation speed of the fan drops to 0 again when temperature is 87 ℃, and fan oil pump 9 interrupts to the liquid stream of oil hydraulic motor 10, because the fan oil pump rotates back into its zero-bit again.
