Background technology
Intercrystalline corrosion be meant along or be close to the corrosion that the metal grain border takes place, be the very big corrosion type of harmfulness that metal strength, plasticity and toughness are reduced greatly.Huey test is metallographic to be polished sample in specific acid solution, carry out heat etching or electro-etching; Then examine under a microscope along the reticular tissue and the intercrystalline crack of brilliant corrosion and evaluate; Or work crooked (90 °); The check table surface state like gloss, hairline vestige and crack etc. and evaluate, is the most important condition whether check raw material metal and test piece for welding satisfy chemical plant production.Because the time cycle of Huey test is longer, in the entire test, the corrosive liquid in the beaker also need keep the boiling time that did not wait in 16 to 120 hours under the situation of boiling.During this period, must make the acidic liquid steam condensing reflux to beaker through the tap water that flows through in the condenser pipe.
Because the various places condition is different, the situation of tap water interrupt delivery can be run in the metallographic chamber in the Huey test process, can directly cause the corrosive liquid in the beaker to evaporate, beaker generation explosion, whole test failure.Influenced manufacturing schedule greatly and corrosive gas enters air, polluted and potential safety hazard arranged.
The utility model content
The goal of the invention of the utility model is: to the problem of above-mentioned existence; The Huey test automaton that a kind of good reliability, volume are little, easy to operate, the life-span is long is provided; This device can alleviate staff's working strength greatly; Conserve water electric energy and experiment consumptive material are effectively increased work efficiency.
The technical scheme that the utility model adopts is such:
A kind of Huey test automaton comprises electric furnace, beaker, condensing reflux pipe, condensation water tank and running water valve, is placed with the brilliant rotten soup beaker that fills acid solution on the said electric furnace; The beaker mouth is provided with the condensing reflux pipe; Running water valve control condensate water flows into condensation water tank through the condensing reflux pipe, is provided with the liquid level inductive probe in the said condensation water tank, and the liquid level inductive probe links to each other with automatic control box; Automatic control box links to each other with electromagnetic relay, and electromagnetic relay links to each other with electric furnace again.
To zero-bit, switch on the automatic control box is got to automated location to clock setting, open running water valve; Air switch closes; This moment, automatic control box got electricly, and the liquid level inductive probe is sensed the condensing reflux pipe has current to flow out, and automaton is connected the electromagnetic relay power supply; Electric furnace is started working, and Huey test begins.
As cut off the water supply, the liquid level inductive probe is not sensed has current to flow out in the condensing reflux pipe, cut off the electromagnetic relay power supply automatically, and electric furnace quits work, and when tap water supplies water again, equipment is task again, and Huey test is proceeded. midway
Said automatic control box links to each other with clock.
Said automatic control box is provided with manually, automatic and three gears of cutting off the water supply.
Said device is supplied power by power supply, by air switch control break-make.
Be provided with electrothermal relay between said electromagnetic relay and the electric furnace.
Electrothermal relay is to produce heat by the electric current that flows into thermal element, makes the bimetallic strip generation deformation of different expansion coefficient, when deformation reaches certain distance; Just promote the connecting rod action, control circuit is broken off, thereby make the contactor dead electricity; Main circuit breaks off, and realizes the overload protection of circuit.
Be provided with insurance between said electromagnetic relay and the automatic control box.
Be provided with pressure regulator between said electrothermal relay and the electric furnace.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
The said Huey test automaton of the utility model; Good reliability, volume is little, easy to operate, the life-span is long; Alleviated staff's working strength greatly, trouble free service under the unmanned situation has been practiced thrift HYDROELECTRIC ENERGY and experiment consumptive material for a long time; Practice thrift manpower and materials, effectively improved production efficiency.
