There is no good method to monitor and find in advance the internal leakage of hydraulic system.And because system temperature mistake caused by internal leakage
Height, makes whole system temperature all increase quickly, it has not been convenient to trace the source of temperature rise.Therefore, we in the urgent need to it is a kind of can be right
Each part carries out the device of temperature monitoring in crane hydraulic system, to grasp the temperature conditions of crane hydraulic system in real time.
The content of the invention
The crane liquid of each part temperatures of crane hydraulic system can be monitored in real time it is an object of the invention to provide a kind of
Press system temperature monitoring system.
The present invention utilization pre-buried temperature sensor or infrared detection technology, detection emphasis Hydraulic Elements and hydraulic system
The temperature conditions of emphasis pipeline, can be timely when external functional fault is not still obvious with the source position of auxiliary judgment internal leakage
It was found that there is the element of earlier period damage sign, it is to avoid the loss that unexpected disorderly closedown is brought.
What the present invention was realized in：
A kind of crane hydraulic system temperature monitoring system, it includes temperature sensor group, and the temperature sensor group will
The temperature signal of collection passes to temperature storage processor, and temperature data is passed to Temperature Treatment mould by temperature storage processor
Block, Temperature Treatment module passes data to monitoring temperature screen and shown；
The temperature sensor group includes being used to detect the infrared temperature sensor of oil cylinder temperature, for detecting pump temperature
Infrared temperature sensor, the infrared temperature sensor for detecting valve temperature, be embedded on hydraulic oil container be used for detect hydraulic pressure
The temperature sensor of tank temperature, be embedded on oil pipe be used for detect the infrared temperature sensor of oil pipe temperature and for detecting
The temperature sensor of atmospheric temperature；
The monitoring temperature screen is placed in hoisting box.
Further scheme is：The Temperature Treatment module is connected with printer.
Further scheme is：The Temperature Treatment module passes data to long-range end by radio receiving transmitting module
End.
The present invention is by each critical piece of host hydraulic system（Such as pump, motor, oil cylinder, control valve）, position（Such as fuel tank,
Fuel sucking pipe, each oil return pipe etc.）Temperature signal collect and be sent to monitoring screen display, to facilitate to the temperature of hydraulic system prison
Control.Thermometric mode is used with pre-buried temperature sensor or infrared detection technology.Can directly pre-buried temperature in such as hydraulic oil container
The place of the inconvenient pre-buried temperature sensors such as sensor, but pump and motor is spent, using infrared measurement of temperature.
The present invention can realize that accumulation temperature shows that mean temperature is shown, inquire about same position different periods（Days are set
Time-division day）Temperature curve, can also inquire about and print the temperature curve that different parts are put at the same time；One can also be stored
The temperature data in section period is used for post analysis.The present invention can also use wireless communication data transmission technology, applied to long-range
Fault diagnosis.The biggest advantage of the present invention is can to show each position at some time point（Element）Transient temperature
Value, transient temperature value highest near sites are exactly the trouble point of internal leakage, and this is for the event of auxiliary judgment leakage of hydraulic system
Barrier is very convenient.
The temperature value at each position can be stored and handled by the Temperature Treatment module in the present invention, can be with required
Time point carries out " screenshotss " display of each position transient temperature, can also analyze change rule of the same position on time latitude
Rule.
The present invention can monitor each critical piece of crane hydraulic system, the temperature at position in real time, operating personnel is slapped in real time
Each critical piece of hydraulic system, the temperature conditions at position are held, quickly and accurately to find leakage of hydraulic system failure source,
Reduce and stopped work caused by leakage, it is ensured that being smoothed out for production, decrease construction cost.Monitoring temperature screen is placed in driving
Interior, is easy to staff to operate and use.Using wireless transmission technology, it is easy to remote fault diagnosis, using more convenient.
