Description
Technical field
It is the present invention relates to engineering truck hydraulic oil preheating technology field, in particular to a kind of pre- using operating room warm air system
The device of thermal technology's journey vehicle hydraulic oil.
Background technique
Oil plant there are certain requirements temperature range.When environment temperature be lower than oil plant adaptive temperature, will lead to oil plant viscosity mistake
Height, flow difficulties are not able to satisfy equipment performance requirement.When environment temperature be higher than oil plant adaptive temperature, will lead to oil plant viscosity mistake
Low, too easy flowing, equipment complex performance weakens significantly.In the big area of Seasonal Temperature Difference, it usually needs replacement adapts to not equality of temperature
The oil plant of degree, to ensure in oil plant in most stateful lower work.
However in China's cold district, outdoor equipment evening environment temperature is very low (such as the Northeast, China).And equipment
After normal work, the ability of equipment working loss is converted into thermal energy, and oil plant is heated to thermal equilibrium temperature (when equipment oil plant works
Temperature and environment temperature dynamic equilibrium).General device all has cooling system, therefore the oil plant operating temperature of winter and summer are poor
It is different smaller.And the minimum temperature of winter and summer difference are larger.And oil plant Acclimation temperature range is not able to satisfy winter temperature variation
Range, when oil plant type selecting based on working condition.Therefore equipment operation difficult problem when equipment generally existing winter low temperature, especially
It is difficult when being the starting of early morning in winter equipment.
The equipment such as engineering machinery such as crane, pump truck, loading machine, excavator are equipped with a large amount of hydraulic oil.Morning in winter liquid
Pressure oil viscosity is larger, and hydraulic device low efficiency is slow in one's movements, influences the normal use of engineering equipment.
Currently, solving the problems, such as this there are mainly four types of method.
One, switched to by the energy of device standby running wastage for heat hydraulic oil.Specific way are as follows: by equipment
Start hydraulic oil pump starting, hydraulic execution structure is failure to actuate, and high pressure liquid pressure oil directly flows back to hydraulic oil container from overflow valve.In this mistake
Cheng Zhong, oil pump loss are converted into thermal energy, heat hydraulic oil.For a period of time, hydraulic fluid temperature can reach suitable for such idle running
Close the temperature of equipment work.Disadvantage: it needs high-power engine standby operation for a long time, fuel consumption is larger, heating efficiency
It is low.
Running causes energy loss for a long time, heats hydraulic oil using the partial heat, hydraulic oil is made to reach normal work
Make temperature.The advantages of this method is that method is simple, is not required to add additional device, but equipment work efficiency reduces, and will cause
Fuel oil waste.
Two, hydraulic oil is preheated by collecting engine exhaust emission heat.Discharge has higher temperature when engine operation
Tail gas, utilize the tail gas heating hydraulic oil of this higher temperature.Specific practice is: the exhaust pipe of engine being connect and connects liquid all the way
Pressure oil case heats hydraulic oil by heat exchanger, then flows to silencer discharge again.Disadvantage: when weather cold, engine itself
It is also at an extremely cold state.Need the self-heating of a period of time.And exhaust pipe in order to guarantee summer high temperature environment when temperature not
It is excessively high, by being designed as the structure easily to radiate.Therefore the efficiency of heating is also not highly desirable.Furthermore tail gas is entering silencer
Before, strict guarantee is needed to be unable to gas leakage (gas leakage will bring serious noise to environment).Increase preheating circuit, will greatly prolong
Exhaust emissions pipeline length, designs the more complicated of change, and system reliability reduces.
Third is that the Hot-blast Heating hydraulic oil being discharged by engine cooling fan.This method is in low temperature, engine radiating
Wind will be cooled down rapidly by the cold air of surrounding, and pre-heat effect is limited.
Fourth is that the hydraulic oil of the directly replacement adaptation more low temperature trade mark.Its advantage is can thoroughly to solve hydraulic oil low temperature
Problem, but the hydraulic oil of lower temperature is needed replacing, it is at high cost, and room temperature hydraulic oil is also needed to change when temperature recovery, otherwise
Hydraulic oil has that viscosity is too low.In conclusion there is presently no a kind of not only economic but also efficient Preheating Engineering vehicle liquid
The method and apparatus of pressure oil.
Summary of the invention
In view of the above problems, operating room warm air system Preheating Engineering is utilized the purpose of the present invention is to provide a kind of

Realize pre-heating function of hydraulic oil.It is characterized by: being equipped with selection switch in the outlet pipe, it is equipped in the hydraulic oil container
Controller and temperature sensor, the controller are separately connected the selection switch and temperature sensor；
After the fuel oil warm air air-conditioning is opened, is switched by the selection and connect the outlet pipe and economizer bank
Logical, part hot water is transported to hydraulic oil container by the outlet pipe, and the heat of generation preheats hydraulic oil, the water after preheating
Fuel oil warm air air-conditioning, such circulating-heating are back to by the return pipe；When the hydraulic fluid temperature in hydraulic oil container is up to
When one temperature value, the temperature sensor sends a signal to the controller, and controller is calculated by internal processes, by institute
The selection switch stated is closed, and stops preheating hydraulic oil, all hot water flow to the operating room by the outlet pipe
Warm wind port, then fuel oil warm air air-conditioning, such circulating-heating are back to by the return pipe.
The above-mentioned device using operating room warm air system Preheating Engineering vehicle hydraulic oil, it is characterised in that: described first
Temperature value is 45 DEG C.
The above-mentioned device using operating room warm air system Preheating Engineering vehicle hydraulic oil, it is characterised in that: the control
Device is mounted on hydraulic oil container by screw, and protective cover is equipped with outside controller.
The above-mentioned device using operating room warm air system Preheating Engineering vehicle hydraulic oil, it is characterised in that: stopping preheating
After hydraulic oil, the described controller continuation is judged according to the signal that temperature sensor issues, when hydraulic fluid temperature is lower than the
When one temperature value, the selection switch be will automatically turn on, and preheat hydraulic oil, such circulating-heating again.
This method have the advantage that: hydraulic oil is preheated by operating room warm air system, can both expand same trade mark hydraulic oil
Thermal adaptability, can be avoided and open high-power engine fuel oil is caused to waste, implement simple, low energy consumption, not only economy but also
It is high-efficient.
