  真空烘干机厂家主要有如下方法:
  There are mainly the following methods:
  故障一:热风循环烘箱温度升不高:
  Fault 1: temperature rise of hot air circulation oven is not high:
  原因1:蒸汽压力太低;方法:按要求提高蒸汽压力
  Cause 1: the steam pressure is too low; method: increase the steam pressure as required
  原因2:疏水器失灵 ;方法:疏水器有杂物阻塞
  Cause 2: the steam trap fails; method: the steam trap is blocked by sundries
  原因3:电加热电压太低;方法:提高网路电压,按要求供电
  Cause 3: the electric heating voltage is too low. Method: increase the network voltage and supply power as required.
  原因4:排湿阀处常开状态;方法:关闭排湿阀
  Cause 4: the dehumidification valve is normally open; method: close the dehumidification valve
  原因5:风机转向不符;方法:电源线两相任意对调
  Cause 5: the direction of the fan is inconsistent; method: the two phases of the power line are randomly adjusted.

  原因6:显示仪表不正确;方法:检查热电阻是否固定良好,接线是否正确。必要时用标准电阻箱校验温度仪
  Reason 6: the display instrument is not correct; method: check whether the thermal resistance is fixed well and whether the wiring is correct. If necessary, use standard resistance box to verify the thermometer
  原因7:没有采取保温措施;方法:CT系列烘箱回管外部加保温层
  Reason 7: no thermal insulation measures were taken; method: add thermal insulation layer outside the return pipe of CT series oven.
  故障二:热风循环烘箱温度不均匀:
  Fault 2: uneven temperature of hot air circulation oven:
  原因1:两侧调风板叶片调正不当;方法:调节两侧调风板间隙大小;
  Cause 1: the blade alignment of the two sides of the air regulator is improper; method: adjust the gap between the two sides of the air regulator;
  原因2:烘门未关严;方法:检查并排除
  Cause 2: the drying door is not closed tightly; method: check and eliminate
  故障三:热风循环烘箱风机噪音大:
  Fault 3: the fan of hot air circulation oven is noisy:
  原因1:风机或电机螺栓松动;方法:检查并排除;
  Cause 1: the bolt of fan or motor is loose; method: check and eliminate;
  原因2:风机叶片碰壳,轴承磨损;方法:检查并排除;
  Cause 2: the fan blade collides with the shell and the bearing is worn; method: check and eliminate;
  原因3:电机二相运转;方法:检查线路及电器开关
  Reason 3: Motor two-phase operation; method: check the circuit and electrical switch
  故障四:热风循环烘箱干燥速度太慢:
  Fault 4: drying speed of hot air circulation oven is too slow:
  原因1:箱内温度太低;方法:见故障1
  Cause 1: the temperature in the box is too low; method: see fault 1
  原因2:排湿选择不当;方法:调整排湿阀开度
  Reason 2: improper selection of dehumidification; method: adjust the opening of dehumidification valve
  原因3:风量太小;方法:检查风机,风管有否漏风和叶片杂物吸上
  Cause 3: the air volume is too small; method: check whether there is air leakage in the fan and air duct and whether there is debris on the blade.
  原因4:热量散失;方法:检查需保温部位是否进行保温
  Cause 4: heat loss; method: check whether the parts to be insulated are insulated.
