Hot deformation Vicat softening point testing machineSuitable for testing the Vicat softening point temperature and thermal deformation temperature of thermoplastic and polymer materials. The configured execution components and sensors have the characteristics of high temperature resistance, low coefficient of expansion, sensitive response, and accurate data transmission, which are particularly suitable for production inspection, development and research of products and materials by pipe manufacturers, product quality inspection stations, construction engineering quality inspection stations, construction companies, scientific research institutions and other units.
The maintenance of the hot deformation Vicat softening point testing machine should focus on the three major modules of temperature control system, mechanical structure, and measurement accuracy. The specific operation is as follows:
Maintenance of temperature control system:
Temperature sensor calibration: Regularly use a multimeter to check the resistance value of the sensor, and replace it if it is abnormal. The parameters of temperature control instruments should be set according to standards (such as ISO75 or GB/T 1633) to avoid program errors that may cause temperature control failure.
Heating element inspection: Confirm that the heater is not broken or has poor contact, and replace it when it ages; Heating media (such as methyl silicone oil) should be kept clean to avoid oil contamination affecting heat conduction.
Mechanical structure maintenance:
Lubrication of moving parts: Ball screws, guide rails, etc. need to be regularly coated with molybdenum disulfide grease, and the gearbox needs to replace the gear oil every year.
Transmission system inspection: The mixing motor, lifting motor, and belt need to be checked regularly. If they are loose or broken, they need to be adjusted or replaced. The sample holder needs to be cleaned of foreign objects and ensure accurate positioning.
