Summary of the invention
The object of the present invention is to provide a kind of crane hydraulic system temperature monitoring system monitoring each part temperatures of crane hydraulic system in real time.
The present invention utilizes pre-buried temperature transducer or infrared detection technology; detect the temperature conditions of the emphasis pipeline of emphasis hydraulic element and hydraulic system; can the position, source of auxiliary judgment internal leakage; when external functional fault is still not obvious, Timeliness coverage has the element of earlier period damage sign, avoids the loss that unexpected disorderly closedown brings.
The present invention is achieved in that
A kind of crane hydraulic system temperature monitoring system, it comprises sets of temperature sensors, the temperature signal of collection is passed to temperature storage of processor by described sets of temperature sensors, temperature data is passed to Temperature Treatment module by temperature storage of processor, and data are passed to monitoring temperature screen and show by Temperature Treatment module;
Described sets of temperature sensors comprise infrared temperature sensor for detecting oil cylinder temperature, for testing pump temperature infrared temperature sensor, for detect valve temperature infrared temperature sensor, be embedded on hydraulic oil container for detect hydraulic oil container temperature temperature transducer, be embedded on oil pipe for detecting the infrared temperature sensor of oil pipe temperature and the temperature transducer for detecting atmospheric temperature;
Described monitoring temperature screen is placed in hoisting box.
Further scheme is: described Temperature Treatment module is connected with printer.
Further scheme is: data are passed to remote terminal by radio receiving transmitting module by described Temperature Treatment module.
The temperature signal of each for host hydraulic system critical piece (as pump, motor, oil cylinder, control valve etc.), position (as fuel tank, fuel sucking pipe, each return tube etc.) is collected and is sent to monitoring screen display, to facilitate the monitoring temperature to hydraulic system by the present invention.Thermometric mode adopts with pre-buried temperature transducer or infrared detection technology.Can direct pre-buried temperature transducer in such as hydraulic oil container, but the place of the inconvenient pre-buried temperature transducer such as pump and motor, adopt infrared measurement of temperature.
The present invention can realize accumulation Temperature displaying, and mean temperature shows, and inquires about the temperature curve of same position Different periods (arranging time-division date), also can inquire about and the temperature curve printing different parts and put at the same time; The temperature data in one period can also be stored for post analysis.The present invention can also adopt wireless communication data transmission technology, is applied to remote fault diagnosis.Maximum advantage of the present invention is the transient temperature value at each position (element) that can show some time points, and the near sites that transient temperature value is the highest is exactly the fault point of internal leakage, and this is very convenient for auxiliary judgment leakage of hydraulic system fault.
The temperature value at each position can be carried out Storage and Processing by the Temperature Treatment module in the present invention, can carry out " screenshotss " display of each position transient temperature, also can analyze the Changing Pattern of same position on time latitude with required time point.
The present invention can monitor the temperature at each critical piece of crane hydraulic system, position in real time, operator are made to grasp the temperature conditions at each critical piece of hydraulic system, position in real time, to find leakage of hydraulic system fault source quickly and accurately, reduce because leaking the shut-down caused, guarantee carrying out smoothly of production, decrease construction cost.Monitoring temperature screen is placed in operator cabin, is convenient to operated by personnel and use.Adopt wireless transmission technology, be convenient to remote fault diagnosis, use more convenient.
