The course of work and the principle of temperature controller durability test instrument of the present invention: earlier the temperature controller temperature-sensing element (device) is used the heat-resisting pressing plate clamping of insulation on copper billet, after the heating tube energising, the heating copper billet, the temperature that thermopair gathers copper billet in real time is housed on the surface of copper billet compares, make whole copper billet reach preset temperature value with detecting the control module preset temperature.Cooling realizes by following mode: surrounding air becomes high pressure draught by air pump and (is applied on the copper coin by 1~4 shower nozzle 0~1MPa), make copper coin part (only with temperature controller sensitive element surface in contact) cooling fast, thereby temperature controller responsive to temperature position temperature is descended, temperature controller resets, thereby finishes the one action circulation.
Compared with prior art, the invention has the advantages that:
(1) the type of heating thermal inertia of Cai Yonging is little, and heating-up temperature can accurately be regulated in room temperature to 500 ℃ scope
Because the good heat conductivity of copper, the temperature field good uniformity on surface, thus realized that heating-up temperature can accurately regulate, range is big, can reach 500 ℃, and this kind type of heating is because firing rate is fast, and thermal inertia is little simultaneously, effectively reduces the influence of hot overshoot to testing result;
(2) temperature controller break-make adjustable-speed scope is big
The first, cooling velocity changes along with the size of the pressure of air-flow, and it is adjustable continuously that cold gas is pressed in 0~1MPa scope, thereby realizes that make-and-break time is controlled; The second, according to the area size of the sensitive element of tested temperature controller, can select 1~4 shower nozzle to apply on the copper coin around the sensitive element of temperature controller flexibly during cooling, realize the local cooling of part, do not need the temperature of whole temperature controller is all lowered; The 3rd, copper billet thermal capacity is big, and temperature recovery speed is fast, thereby has realized the break-make EDM Generator of Adjustable Duty Ratio, and controlled range is big, so this temperature controller durability test instrument break-make adjustable-speed scope is significantly improved;
(3) press close to temperature controller real work situation, improve the degree of accuracy of test result
In whole endurancing process, measured piece is fixed on the copper coin, presses close to the working condition of temperature controller reality most, and is also minimum to result's influence, improved the degree of accuracy of test result;
(4) simple in structure, with low cost, highly versatile
Equipment set is simple in structure, and is with low cost, and highly versatile is safeguarded simple, temp sensing controller is various in style, and physical dimension is different, as long as the one side that this equipment is found accurately near temperature-sensing element (device) is attached on the copper billet, push down with the high temperature insulation pressing plate, simple to operate, easily and effectively.
Further, therefore can prolong the serviceable life of heating arrangement because electrothermal tube is positioned at the position, lower middle of copper billet, and cold and hot variation is less, and is not fragile.
