An open double cone rotary vacuum dryer , and the Power LED should light , temperature controller Power On Self Test , PV display the working chamber measuring temperature , SV display is factory set temperature. Temperature control device on the AT and HEAT and other lights should be lit , that instrument into the heating working condition.
Second, modify the set temperature :
1 , click the temperature controller function key (SET); PV display SP characters , the available key head button to set the temperature changes.
2, the modification is completed , press the SET button , PV display ST characters , set the timer time . If you do not use the timer function , you can still let ST = 0
3 , press the SET button , the screen display studio temperature PV , SV screen displays the new set temperature. AT AND HEAT instrument lights , then re-enter the meter heated working condition.
4, if the work room double cone rotary vacuum dryer for humidity, water vapor generated will affect the performance of the vacuum pump , double cone rotary vacuum dryer is recommended between the enclosure and the vacuum pump , the string into a " double cone rotary vacuum dryer / filter . "
5 , if the double cone rotary vacuum dryer items in the process, need to add nitrogen and other inert gases, should be specified in the contract , was equipped with an inlet valve .
Third, when the working chamber temperature close to the set temperature , HEAT lamp light suddenly flickered , which means that the heating stage into the PID regulator , the instrument is sometimes measured temperature exceeds the set temperature, sometimes below the set temperature is normal. When measuring the temperature close to or equal to the set temperature , and then the studio until 1 ~ 2h after entering a constant temperature, items into the double cone rotary vacuum dryer phase.
Fourth, the desired temperature is low , we can use the second set methods, such as the required operating temperature 70 ℃, the first time to set 60 ℃, such as temperature overshoot began to fall , and then the second set 70 ℃ , which can reduce or even eliminate temperature overshoot phenomenon , as soon as possible into the constant temperature.
Five , when the double cone rotary vacuum dryer after use , turn off the power , if accelerated cooling, then open the bleeder valve so that the vacuum is 0 , for 5 minutes or so call box door .
The double cone rotary vacuum dryer vacuum debugging :
a) The double cone rotary vacuum dryer box door and tighten the door handle in place , close the bleeder valve ( the rubber stopper on the bleed valve hole and the holes on the twisted side 90 °), open the vacuum valve ( by the counterclockwise rotation 90 °), the first use of a vacuum valve switch may be tight, be forced to rotate.
b) Using random accessories vacuum connection tube ( inner diameter : Φ16mm thickness : 10mm) box will double cone rotary vacuum dryer exhaust pipe ( diameter : Φ16mm) and a vacuum pump (2XZ-2 type , the inlet diameter Φ16mm) connected securely ( 6090 and 6210 has been connected ) .
1 Switch on the vacuum pump power and began pumping , when the vacuum gauge indicates the value reached -0.1Mpa , first turn off the vacuum pump valve is closed after power to prevent vacuum pump oil to flow back into the working chamber , ( 6090 and 6210 without vacuum valve can be turn off the vacuum pump power directly on the panel ) double cone rotary vacuum dryer at this time inside the vacuum in a vacuum state.
2 double cone rotary vacuum dryer rack : the steel and welded steel plate cylinder connected with about two axes , two double row spherical roller bearing on the rack . Tube : for extracting solvent evaporation tank ( or water ) vapor , made of SUS304, at the inlet end fitted with filters should be used with industrial coated polyester flannel to prevent the material out . |
