Description
Technical field
The detection that the hydraulic pressure oil product was revealed when the utility model related to a kind of online fluid pressure line and moves continuously belongs to hydraulic pressure checkout equipment technical field.
Background technology
In rolling production, it is a difficult point that continuous rolling production line rolling mill hydraulic pipeline oil leak detects always, and the reason of detection difficult mainly is not reveal warning device in the fluid pressure line; Do not establish at Hydraulic Station under operator on duty's the situation; Leakage soon leaked to produce not have at a FCL hydraulic oil often and just come to light when oil is reported to the police, and delay the time that discovery is revealed, and a large amount of hydraulic oil waste; Both increase production cost, polluted environment again.
The utility model content
The utility model technical problem to be solved provides a kind of online fluid pressure line leak detecting device that can find in time in process of production that oil product is revealed and reported to the police in the fluid pressure line.
The technical scheme that solves the problems of the technologies described above is:
A kind of online fluid pressure line leak detecting device; It is made up of liquid level detection device, programmable controller, warning device; Liquid level detection device is installed in outside the Hydraulic Station fuel tank; The signal output part of liquid level detection device is connected with the signal input part of programmable controller, and the signal controlling end of programmable controller is connected with warning device.
Above-mentioned online hydraulic system leakage checkout gear; Said liquid level detection device is made up of magnetic float liquid level gauge and magnetosensitive switch; Magnetic float liquid level gauge and magnetosensitive switch are installed in outside the Hydraulic Station fuel tank; The magnetosensitive switch is a plurality of, and the magnetosensitive switch is arranged in the first-class fixed distance of liquid level gauge standpipe vertical direction, and the signal output part of each magnetosensitive switch is connected with the signal input part of programmable controller.
Above-mentioned online hydraulic system leakage checkout gear, said liquid level detection device is a linear position sensor, and linear position sensor is installed in outside the Hydraulic Station fuel tank, and the signal output part of linear position sensor is connected with the signal input part of programmable controller.
The beneficial effect of the utility model:
The utility model can find in time effectively that through liquid level detection device, programmable controller, warning device oil product is revealed in the fluid pressure line; Guaranteed when the oil leak amount is little, just can in time produce warning; Identifying need not artificially be participated in, and has very high intelligent characteristic.The utility model is simple in structure, making is easy, with low cost, easy for installation, result of use reliably, is not destroyed original hydraulic test, is convenient to implement and promote.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark is following among the figure: Hydraulic Station fuel tank 1, magnetic float liquid level gauge 2, magnetosensitive switch 3, programmable controller 4, warning device 5.
The specific embodiment
The utility model is realized the identification to the hydraulic system oil leak through oil level decrease speed speed in the monitoring Hydraulic Station fuel tank.The discontinuity position metering system that oil level in the Hydraulic Station fuel tank can adopt switch to measure is measured, and also can adopt linear position sensor to carry out the continuous position metering system and measure.
In steel rolling was produced, a cover hydraulic system wanted to realize not having fully that to reveal be difficulty very, in the production reality amount of leakage of hydraulic test was had the scope of a permission, and the amount of leakage of this permission is at T
0Allow liquid level decline △ h to represent in time (this value manual work preestablishes).
Show among the figure; When the oil level in the Hydraulic Station fuel tank 1 adopts the discontinuity position metering system, magnetic float liquid level gauge 2 is installed outside Hydraulic Station fuel tank 1, float is magnetic in its standpipe; Standpipe is vertically placed; Many magnetosensitive switches 3 of equidistant arrangement are installed on the vertical direction of standpipe, and the signal output part of each magnetosensitive switch 3 is connected with the signal input part of programmable controller 4, and the signal controlling end of programmable controller 4 is connected with warning device 5.Magnetosensitive switch 3 reaches programmable controller 4 with liquid level information, is handled by the liquid level information that 4 pairs of programmable controllers collect.If the time interval t that vertical range is adjacent two magnetosensitive switch 3 states of △ h occurs the trailing edge variation successively is less than time value T
0, exceeded rational leakage rate with regard to the whole fluid pressure line of decidable.
When the oil level in the Hydraulic Station fuel tank 1 adopts the continuous position metering system, if at T
0Time liquid level dropping distance judges then that greater than the dropping distance △ h that allows hydraulic system has taken place more seriously to leak.Two kinds of metering systems are compared because the latter can △ h set very little, and the former receives the restriction of installing space can't accomplish this point, so the resolution ratio of latter's identified leakage can be higher, advantage is more obvious.
When programmable controller 4 detects the hydraulic system leakage generation, can report to the police by automatic control alarm device 5, prompting monitoring personnel take the handled measure immediately.
