    Description

    Method for extending the service life of WSS-401 Bimetallic thermometer of Shanghai automation instruments
    1 description of the problem
    Caused by the pointer thermometer, and 3 hours of electrolyte, the electrolysis battery works chrome plating with a tube of titanium 1 protection tube bimetal thermometer is I do not move the operating temperature of the 120 ° bimetallic strip corrosion temperature, the workpiece surface does not make hot and cold The chrome heat treatment has been difficult to know.
    2 analysis of the problem
    Titanium is difficult to corrode precious metals, electrolysis, this phenomenon is very obvious because the purity of titanium is not enough. However, the purchase of a protective tube thermometer bimetal high purity titanium on the market is more difficult and cost prohibitive.
    3 solutions
    And corrosion resistance, it is difficult to protect the tube from titanium in the jacket or protection tube, so it is recommended to choose plastic tube as the material.
    4 applications, effects
    It can be seen that the corrosion resistance of the plastic pipe is superior to that of pure iron, and the low carbon steel is at 120 ° C, excellent heat insulation, light weight, low price and resistance. A bimetal thermometer finds a plastic tube with an inner diameter of 12 mm, which is 12 mm. The tube is 510 mm long, then the other end of the thermo-compression bonded plastic tube is protected by a tube of 500 mm or less. After the mercury inertia of the mercury thermometer is about 10 seconds of water bathing, the plating temperature changes to slow down the temperature due to changes in the temperature of the cell, compared to global warming, the thermal inertia is negligible. The good news is that, from 1995 to the present, for 13 years, these have proved that this method is effective and can be already in operation. In the future, we have not tried this method, if a similar situation occurs.
    When choosing a bimetal thermometer, you should fully consider the actual application environment and requirements, such as dial diameter, accuracy grade, mounting and fixing methods, type of media to be tested, and environmental hazard. In addition, we must pay attention to factors such as cost performance and maintenance workload. In addition, during the transportation, installation and use of the bimetal thermometer, the temperature probe should be avoided. To ensure the accuracy of the measurement, the length of the probe to be rubbed into the measured medium should be no less than 2/3 of the length of the probe. Do not twist the instrument case.
