Abstract
The present invention discloses a kind of engine water temperature high-temperature protection method, and it comprises the following steps：Step one：When the temperature of water is more than 105 °C, if temperature is also rising, the electric-control system of engine can be reduced the electric current for flowing to moment of torsion control magnetic valve, system model is changed into L；Step 2：When continuing to be reduced to 102 °C, it is changed into S mode；Step 3：Continue to reduce temperature, when temperature is reduced to 98 °C, the automatic protection that system is automatically restored on original power mode, monitor cancels display.During by using inventive engine water temperature high-temperature protection method, in the case that engine water temperature rises to necessarily, allow electric-control system to adjust power mode, so as to reduce the power output of pump, power output is diminished, make the reduction of engine water oil temperature.Until temperature is reduced to normal working range, and then it is effectively protected engine system.
Description
Technical field：
The present invention relates to engine water temperature high-temperature protection method, it belongs to engine art.
Background technology：
Excavator, is to be excavated to be higher or lower than the material for holding machine side with scraper bowl, and load haulage vehicle or unload to rickyard
Earthmoving machinery.The material that excavator is excavated is mainly soil, coal, silt and soil and rock after pre- pine.From near
From the point of view of the development of several years engineering machinery, the development of excavator is relatively fast, and excavator has become topmost in engineering construction
One of engineering machinery.
Wherein excavator in the case that digging machine radiating is bad, starts when frequent operation, or in hot summer
Machine temperature is higher, so has infringement to engine system.
Therefore, it is necessory to be improved to prior art to solve the deficiency of prior art.
The content of the invention：
It is an object of the invention to：A kind of engine water temperature high-temperature protection method of excavator is provided, it can be effective
Protect engine system.
The present invention is adopted the following technical scheme that：A kind of engine water temperature high-temperature protection method of excavator, it includes as follows
Step
Step one：When the temperature of water is more than 105 DEG C, if temperature is also rising, the electric-control system of engine will can flow
Reduced to the electric current of moment of torsion control magnetic valve, engine system pattern is changed into L；
Step 2：When temperature is reduced to 102 DEG C, engine system is set to be changed into S mode；
Step 3：Continue to reduce temperature, when temperature is reduced to 98 DEG C, engine system automatically restores to original power mould
Automatic protection on formula, monitor cancels display.
In above-mentioned steps, if water temperature was not reduced to 98 DEG C in 15 minutes, engine system is changed into S mode, treats
98 DEG C are reduced to, then returns to original power mode.
The present invention has the advantages that：During by using inventive engine water temperature high-temperature protection method, when starting
In the case that machine water temperature rises to necessarily, allow electric-control system to adjust power mode, so as to reduce the power output of pump, make output work
Rate diminishes, and makes the reduction of engine water oil temperature.Until temperature is reduced to normal working range, and then it is effectively protected engine
System.
Brief description of the drawings：
Fig. 1 is the schematic flow sheet of inventive engine water temperature high-temperature protection method.
Embodiment：
Refer to shown in Fig. 1, in inventive engine water temperature high-temperature protection method when engine water temperature rise to it is certain
In the case of, power mode is adjusted by electric-control system, so as to reduce the power output of pump, power output is diminished, makes engine
Water oil temperature is reduced.Until temperature is reduced to normal working range.
The engine water temperature high-temperature protection method of excavator of the present invention mainly comprises the following steps：
Step one：When the temperature of water is more than 105 DEG C, if temperature is also rising, the electric-control system of engine will can flow
Reduced to the electric current of moment of torsion control magnetic valve, engine system pattern is changed into L；
Step 2：When temperature is reduced to 102 DEG C, engine system is set to be changed into S mode；
Step 3：Continue to reduce temperature, when temperature is reduced to 98 DEG C, engine system automatically restores to original power mould
Automatic protection on formula, monitor cancels display.
In above-mentioned steps, if water temperature was not reduced to 98 DEG C in 15 minutes, engine system is changed into S mode, treats
98 DEG C are reduced to, then returns to original power mode.
By inventive engine water temperature high-temperature protection method, in digging machine frequent operation or in hot summer, digging machine
It can preferably radiate, and then protect engine system.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
Claims (1)
1. a kind of engine water temperature high-temperature protection method of excavator, it is characterised in that：Comprise the following steps,
