uum dryer whow to operate in order to extend the service life?
Into the sample measured in a vacuum dryer, and then removing the composition of the sample can take away the gas, should be the first cabinet warm-up, first heating the sample, then sample when exposed to heat expansion, good vacuum oven passwordwhen the sample expansion to generate pressure to make the bursting of the observation window, which is a potential danger.
  Vacuum Dryer heating of the gas be directed to the vacuum pressure gauge, vacuum gauge will have a temperature rise. If the temperature exceeds the use of specified temperature range of vacuum pressure gauge, can make the vacuum gauge indication error. The first warming heat pulls out the vacuum operation of the program, the heated air vacuum pump out to go, the heat will certainly be brought to vacuum pump up, leading to the vacuum pump temperature is too high, it is possible so that the vacuum pump reduced efficiency. The correct way to use first vacuum and then heating up heating. Be reached after a decline in the degree of vacuum in the rated temperature is appropriate plus pumping. Doing so is beneficial to extend the useful life of equipment.
  Vacuum dryer to use these steps:
  A workpiece into the vacuum dryer vacuum in order to take away the workpiece material can take away the gas composition. If the workpiece is heated gases when heated, it expands. The enormous pressure generated by the vacuum dryer tightness is very good, the expanding gas may be the observation window of tempered glass burst. This is a potential danger. First vacuum and then heating up the heating program operation can be avoided this danger.
  2) if the first warming heat pulls out the vacuum operation of the program, the heated air vacuum pump out of time to go, the heat will certainly be brought to vacuum pump up, leading to the vacuum pump temperature is too high, it is possible so that the vacuum pump reduced efficiency.
  3) the heating of the gas be directed to the vacuum pressure gauge, vacuum pressure gauge temperature rise. If the temperature exceeds the use of specified temperature range of vacuum pressure gauge, can make the vacuum gauge indication error.
