(1) the fuel tank in the middle part adopts 20 mm thick thermal insulation material of high temperature 350 ℃, can maximize the guarantee of energy loss in the process of heating tank.
(2) the cooling tube is made from a copper tube with a diameter of 10mm, and the thermal conductivity is strong, with the water cooling, it can quickly transfer the heat in the tank to the effect of rapid cooling.
(3) a seamless stainless steel tube with a diameter of 8mm diameter is made of the heating tube, which is equipped with heating resistance wire, which can produce a quick and stable heat source.
(4) using silicone oil tank and transformer oil as heating medium, heating, heating tube with U with RKC waalwijk heating temperature control table control, temperature control range for room temperature to 300 ℃, using spiral copper tube is cooled.
(5) high precision.The displacement sensor adopts a high-precision Swiss imported micrometer, and the resolution is 0.001 mm, which is indirect contact with the sample.Rapid transfer of sample deformation data to a dedicated configurator electronic integration plate with accuracy of up to or minus 0.005mm;Temperature controller adopts imported from Japan RKC waalwijk temperature control table, accurate temperature control, temperature control of error of plus or minus 0.5 ℃;
(6) the deformation is small.Sample link rod and load choose the same diameter of low expansion alloy rod, thermal deformation of the tiny sample, greatly improve the accuracy of test results, lifting structure bearing capacity is strong, steady lifting sample frame without shaking.
(7) thermal deformation and temperature test of VICAT softening point can be carried out.
(8) good stability.After the sample frame is used in the new material, the overall thermal deformation is smaller and the long-term test stability is higher.The test results were more accurate.
