Description
Technical field
The utility model relates to quality detection device field, is specifically a kind of thermal deformation pick-up unit of Pall ring of the heat distortion amount for detection of Pall ring.
Background technology
Pall ring, is a kind of filler, is the filler in the chemical tower being mainly used in chemical plant, pharmaceutical factory and each water treatment system.At present, the multiplex pottery of the material of Pall ring, metal and common engineering plastics are made.Due to the working environment of Pall ring, be the exchange of carrying out gas phase and liquid phase in chemical enterprise tower, and the media such as the various acid-alkali salts that exchange in tower there is strong corrosivity, and easily stick incrustation at filling surface.So, the many employings of Pall ring of the prior art have corrosion resistant engineering plastics makes, and Pall ring is subject to the impact of environment temperature can produce metaboly, and this all will have influence on the usability of Pall ring, therefore, Pall ring will be through the detection of overheating deforming before production is dispatched from the factory.The detection method of prior art is generally that the position that first Pall ring need to be measured is measured, draw one group of data, then Pall ring is put into heating arrangement, as micro-wave oven, after heating certain hour, from heating arrangement, take out, then measure with survey instrument, go out again one group of data, finally these two groups of data are compared and draw testing result, analyze this result and learn that whether the heat distortion amount of this tested Pall ring is qualified.But there is following shortcoming in this detection method:
1) Pall ring is taken into taking out from micro-wave oven owing to needing in testing process, very trouble operates;
2) simultaneously, because the position of the Pall ring of twice measurement in front and back also can produce deviation, thereby make the data of measuring also produce deviation, cause last measurement data inaccurate.
Utility model content
Technical problem to be solved in the utility model is, a kind of easy to operate, thermal deformation pick-up unit of measuring accurate and visual Pall ring is provided.
For solving the problems of the technologies described above, the thermal deformation pick-up unit of the Pall ring that the utility model provides, it comprises heating cabinet, base assembly, deformation-sensing assembly and pressure load assembly, described base assembly and pressure load assembly are all arranged in heating cabinet, and detected Pall ring is positioned on base assembly and with the lower end in contact of pressure load assembly and is connected; The lower end of deformation-sensing assembly is positioned at heating cabinet and is connected with Pall ring, and upper end is positioned at outside heating cabinet and is placed on heating cabinet top; Described pressure load assembly comprises pressing plate, depression bar, load-bearing plate and counterweight, and the lower surface of described pressing plate is connected with Pall ring contact, and one end of depression bar is connected with the center of pressing plate, and the other end is connected with load-bearing plate, and counterweight is positioned on load-bearing plate; Lower end and the pressing plate of deformation-sensing assembly push against.
Described base assembly comprises base plate, upper plate and four guide pillars, and described base plate is connected by four guide pillars that are distributed on four angles with upper plate; Described pressing plate is slidably fitted on guide pillar.
On described guide pillar, be carved with scale.
Described deformation-sensing assembly comprises deformation-sensing bar, dial gauge and supporting seat, and described supporting seat is positioned at the top outside heating cabinet, and dial gauge is connected on supporting seat; Described one end of deformation-sensing bar and the thimble of dial gauge push against, and the other end pushes against through venthole and the pressing plate at heating cabinet top.
The described axis of deformation-sensing bar and the axis of Pall ring is vertical and parallel with the axis of depression bar.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
1) because pressure load assembly and base assembly are all positioned at heating cabinet, the upper end of deformation-sensing assembly is connected to outside heating cabinet, lower end pushes against with detected Pall ring together with pressure load assembly, like this in the time that heating cabinet makes Pall ring produce deformation, the profile of Pall ring changes, make pressure load assembly along with the deformation of Pall ring is slided in cunning on base assembly, thereby deformation-sensing assembly is reflected this deformation, therefore, testing staff does not need Pall ring to be taken from heating cabinet into taking out, more can facilitate, outside heating cabinet, the deformation of Pall ring is detected and observed intuitively,
2) because the detection of profile before and after Pall ring heating is all carried out on same position, and be directly to draw detection data by installing, therefore avoided the manual error of manual detection, make to detect data more accurate.
