Abstract
The invention provides an oil leak monitoring system of a hydraulic servo pump station, which can monitor whether a liquid road system leaks oil or not in real time and also monitor a concrete oil leakage position when used for a pump station and has very high safety and practicability. The oil leak monitoring system of the hydraulic servo pump station comprises a hydraulic oil source, the hydraulic oil source is connected with a high-pressure output oil pipeline, a backflow oil pipeline and an overflow oil return pipeline; the high-pressure output oil pipeline, the backflow oil pipeline and the overflow oil return pipeline are respectively provided with a flow transducer; the oil surface of the hydraulic oil source is provided with a buoy; and the buoy is connected with an LVDT (linear variable differential transformer) differential repressing-device displacement transducer. The oil leak monitoring system is characterized by also comprising a controller, and the flow transducers and the LVDT differential repressing-device displacement transducer are connected with the controller in an electronic control way.
Description
Technical field
The present invention relates to oil leak monitoring system, be specially oil leak monitoring system of hydraulic servo pump station.
Background technique
Pumping plant is a huge hydraulic system, follows the turnover of hydraulic oil, and part seepage and loss are normal.But along with using the remote of age, whole liquid-way system leakage proof is just relatively more difficult, occurs easily when serious leaking, especially at dead of night, owing to do not have special personnel to check, the timely inspection that has, also cause occurring the serious leakage of oil easily because of personnel's sleepiness, cause accident to take place.
Summary of the invention
At the problems referred to above, the invention provides a kind of oil leak monitoring system of hydraulic servo pump station, use it for pumping plant, can real-time monitor liquid-way system and whether have leakage, and can monitor the position of concrete leakage, Security, practicability are very high.
Its technological scheme is real such: it comprises hydraulic oil source, described hydraulic oil source connects high pressure output oil pipe road, withdrawing oil pipeline, overflows back oil pipe line, described high pressure output oil pipe road, withdrawing oil pipeline, overflow back oil pipe line and be separately installed with flow transducer, the oil meter face of described hydraulic oil source is provided with buoy, described buoy connects the differential re-pressure device displacement transducer of LVDT, it is characterized in that: it also comprises controller, and described flow transducer, the differential re-pressure device displacement transducer of LVDT and described controller electricly connect.
System of the present invention is used for pumping plant, the flow of each hydraulic pipe line is all in monitoring range like this, in case it is unusual which piping flow to occur, and displacement amount in conjunction with buoy, the leakiness that can timely monitor fluid road and the general orientation of leakage can adopt remedial measures timely, prevent that big leakage accident from taking place, safe, practicability is good.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
See Fig. 1, the present invention includes hydraulic oil source 5, hydraulic oil source 5 connects high pressure output oil pipe road 10, withdrawing oil pipeline 8, overflows back oil pipe line 9, high pressure output oil pipe road 10, withdrawing oil pipeline 8, overflow back oil pipe line 9 and be separately installed with flow transducer 1,6,7, the oil meter face of hydraulic oil source 5 is provided with buoy 2; buoy 2 connects the differential re-pressure device displacement transducer 4 of LVDT; the present invention also comprises controller 3, and flow transducer 1,6,7, the differential re-pressure device displacement transducer 4 of LVDT electricly connect with controller 3.
