A kind of method and its device for realizing oil leak detectionTechnical field
The present invention relates to oil leak prevention and control field, especially a kind of method and its device that can realize oil leak detection, can be used for the security control of oil leak, it is to avoid the generation of oil leak accident.
Background technology
At present, happened occasionally in the hydraulic fluid leak of metallurgy industry hydraulic test, in petroleum chemical industry, oil leak accident often occurs, if once oil leak occur can not find in time, often cause big accident, a series of problems, such as huge security threat and environmental pollution being produced to surrounding, huge loss and influence is caused to factory and society, how to prevent oil leak needs to start with from many aspects, oil leak is alarmed and control is the necessary means for preventing oil leak from magnifying, therefore is found in time as the key point for avoiding accident from occurring.
Existing oil leak Detection Techniques use sensor, flammable gas alarm, fiber-optic probe, infrared acquisition mostly, the oil leak detection detection method such as cable, but because oil types characteristic is different and the limiting factor of various natural environments causes its security, reliability aspect to there is very big defect.
The content of the invention
A kind of potential safety hazard caused the invention aims to solve oil leak to find in time, there is provided method and its device that can realize oil leak detection.The method is using the oil leak detection device for being fixed on oil leak at, use water-oil separating material therein, the oil that will be flowed through in its liquid is stored, and by the use of storage oily liquid level as triggering medium, oil leak detection device is set to send switching signal, selected for alarm and remote control, wherein water-oil separating material be have or thoroughly oil block water or permeable oil resistance characteristic material.
The object of the present invention is achieved like this：A kind of oil leak detection device, it includes water-oil separating material, oil storage box and liquid-level switch, and water-oil separating material is arranged on oil storage box, and liquid-level switch is fixed on oil storage box body；Set location of the described water-oil separating material in the shoe cream room of oil storage box is different according to water-oil separating material characteristic difference, and such as saturating oil of water-oil separating material blocks water, then water-oil separating material is arranged on oil storage box top；Such as the permeable oil resistance of water-oil separating material, then water-oil separating material is arranged on the side or bottom of oil storage box inwall；Described oil storage box concrete structure is different according to water-oil separating material characteristic difference, and such as saturating oil of water-oil separating material blocks water, and oil storage box is not provided with apopore；If the permeable oil resistance of water-oil separating material water hole is set out on oil storage box on the outside of set water-oil separating material；There is fixed support on described oil storage box；Described liquid-level switch is contact liquid-level switch or Non-Touching Type Liquid Level Switch.
Operation principle of the invention is：Liquid flows through fixed support and is fixed on oil leak detection device of the oil leak at, if liquid is that water and the saturating oil of water-oil separating material block water, water flows through from the water-oil separating material of oil storage box top, the shoe cream room of oil storage box can not be entered, no liquid in shoe cream room, liquid-level switch does not send switching signal；If liquid is water and the permeable oil resistance of water-oil separating material, water flows into the shoe cream room of oil storage box, and then across the apopore outflow that water-oil separating material is set from oil storage box side or bottom, no liquid in shoe cream room, liquid-level switch does not send switching signal；If liquid is oily, due to water-oil separating material or oil or oil resistance thoroughly so that oil is stored into oil storage box is interior, and when the liquid level of oil in oil storage box reaches setting height, triggering liquid-level switch sends switching signal.
What the present invention was provided realizes that the method for oil leak detection and its innovative point of device are its effective water-oil separating characteristic using water-oil separating material, oil leak detection device is set to send switching signal, selected for alarm and remote control, can accomplish to send alarm control signal in time in oil leak, inspection personnel's very first time is set to understand the failure for occurring, take measures in time, it is to avoid accident occurs.
The present invention provide with realize the advantage of oil leak detection device that the method that oil leak is detected is made be round-the-clock use, simple structure, it is reliable, be easily installed, wide adaptability.
