Description
Technical field
The present invention relates to a kind of airtight check and fluorescent penetrating inspection technology of centrifugal casting furnace tube, particularly relate to a kind of association system and inspection process thereof that the airtight check and the fluorescent penetrating inspection robotization of centrifugal casting furnace tube are carried out.
Background technology
There are defectives such as pore, slag inclusion, crackle in centrifugal casting furnace tube unavoidably on the surface of indivedual boiler tubes, only with the naked eye checks to have omission.Can 100% check the tube-surface defective of coming out of the stove with the method for fluorescent penetrating inspection.Centrifugal casting furnace tube simultaneously, especially little thin walled tube extremely no matter the penetrability defective may occur, because boiler tube is to use, must guarantee that the penetrability defective does not appear in boiler tube under the occasion of High Temperature High Pressure, every boiler tube must carry out airtight check for this reason.
General boiler tube producer boiler tube airtight and fluorescent inspection use two cover tooling devices to test as two cover operations.So both the lost labor wasted the place again, and plant factor is low.
For airtight check, the method that general boiler tube manufacturer tests to the boiler tube surface with artificial brushing suds, but in the process of check, boiler tube two must be blocked, feed gases at high pressure then and carry out airtight check, again the plug at two be cut away after having inspected.Adopt this airtight method of inspection to have following shortcoming: 1. owing to adopt artificial brushing, can't guarantee that the boiler tube surface all can be brushed to, so test effect is poor, efficient is extremely low, and this method can't realize robotization simultaneously, has increased the production cost of boiler tube; 2. owing to adopt artificial brushing, suds unnecessary in the brushing process can drip on the mill floor, can form many spots after having done, and have influenced workshop condition; 3. must carry out shutoff before the check, so not only consuming time but also consume the worker.
For fluorescent penetrating inspection, general boiler tube manufacturer brushes the method that fluorescence liquid is tested to the boiler tube surface with artificial, but contains volatile, harmful material such as acetone in the fluorescence liquid, and contaminated environment.This method had both been wasted fluorescence liquid, again contaminated environment for the inspection process of producing boiler tube in batches; And test effect is poor, and efficient is extremely low.
Though France boiler tube manufacturer is fluorescent inspection and the tightness test test of putting together.But use instead boiler tube is immersed in method in the fluorescence liquid bath, though process efficiency, effect improve, fluorescence liquid is for a long time in groove, evaporate in the air easily, human body is produced harm, and easily by contaminated, thereby can't keep the original check sensitivity of fluorescence liquid.
Summary of the invention
The object of the invention is to provide a kind of centrifugal casting furnace tube fluorescent penetrating inspection and airtight check united automatic system and inspection process thereof, form with streamline is combined airtight check and fluorescent penetrating inspection, adopt the method that sprays suds or fluorescence liquid to be coated in the surface of boiler tube, and unnecessary suds or fluorescence liquid are collected, go out to carry out recycling repeatedly by pump pressure, save material.
Technical scheme of the present invention is achieved in that
A kind of centrifugal casting furnace tube fluorescent penetrating inspection and airtight check united automatic system, form in order by airtight verifying attachment, fluorescence spray equipment and fluorescent penetrating inspection device, described three devices are formed by frame and equally distributed raceway, it is characterized in that: the frame of described airtight verifying attachment and fluorescence spray equipment is provided with two carriages that boiler tube is lifted, described frame be provided with boiler tube fix, and revolvable clamp device, be provided with the gas interface channel in an end centre of the clamp device of described airtight verifying attachment; Bottom in described frame is provided with pallet, is provided with storage tank in the bottom of described pallet, is provided with brace summer on the top of described frame, is lifted with the shower nozzle that moves around on described brace summer, is connected with pump by pipeline between described shower nozzle and the storage tank; Front end at described three devices is provided with spray system;
The spray system of described fluorescent penetrating inspection device is connected with boiler, and the other end of described frame is provided with failure detector.
A kind of centrifugal casting furnace tube fluorescent penetrating inspection and airtight check joint survey technology, boiler tube is pushed on the raceway of airtight verifying attachment, starting its spray system cleans boiler tube, after boiler tube runs to frame central, close spray system, carriage rises, boiler tube is lifted, clamp device starts, and boiler tube is clamped, and carriage descends;
Start shower nozzle then and clamp device is rotated, at boiler tube surface spraying suds, the gas interface channel from clamp device one end feeds gases at high pressure simultaneously, carries out airtight observation;
After airtight observation was finished, clamp device stopped operating, and carriage rises, and unclamps clamp device, and carriage descends, and boiler tube is placed on the raceway of frame, started raceway, and boiler tube is transported on the fluorescence spray equipment;
When boiler tube enters the fluorescence spray equipment, start its spray system, the suds on boiler tube surface are washed, after boiler tube runs to frame central, close spray system, carriage rises, and boiler tube is lifted, and clamp device starts, and boiler tube is clamped, and carriage descends;
Start shower nozzle then and clamp device is rotated, at boiler tube surface spraying fluorescence liquid;
After spraying was finished, clamp device stopped operating, and carriage rises, and unclamps clamp device, and carriage descends, and boiler tube is placed on the raceway of frame, started raceway, and boiler tube is transported on the fluorescent penetrating inspection device;
When boiler tube enters the fluorescent penetrating inspection device, start its spray system, the fluorescence liquid on boiler tube surface is washed, open failure detector, boiler tube is observed.
When boiler tube entered the fluorescent penetrating inspection device, the hydraulic pressure of spray system was not more than 0.27MPa, and water temperature is 15～40 ℃.
The present invention compared with prior art has following advantage:
1. unnecessary suds are collected in the storage tank, can not influence the environment in workshop, and are not easy contaminated and volatilization, thereby keep the original check sensitivity of suds; Unnecessary fluorescence liquid is collected in the storage tank, can not evaporate in the air, can not produce too much harm to human body, and be not easy contaminated, thereby keep the original check sensitivity of fluorescence liquid.
2. adopt the method for spraying, can make the boiler tube surface-coated even, improve the reliability of check, and fluorescence liquid do not pollute surfaces such as boiler tube endoporus, end face in spraying process, reduced back road treatment process.
3. when carrying out airtight check, need not boiler tube is carried out shutoff, directly adopt clamp device to carry out shutoff, reduced Qian Dao and road, back treatment process.
4. adopt this verifying attachment, can save consumptive material, saved manpower, and can realize robotization, greatly improved the work efficiency of boiler tube check.
