|Double cone rotary vacuum dryer maintenance and commissioning of technical information
The double cone rotary vacuum dryer to use the environmental requirements:
a) Temperature: 5 ~ 40 ° C
b) Relative humidity: ≤ 85%
c) Power voltage: AC220V ± 10%
d) around the strong vibration and corrosive gases
The double cone rotary vacuum dryer machine, vacuum debugging:
a) the box shut the door and door handle is tightened in place, close the release valve (so that the rubber stopper on the hole and put the valve hole twisted partial 90 °), open the vacuum valve (by the counterclockwise rotation of 90 °), time may be vacuum tight valve switch can force rotation.
b) using random accessories vacuum connecting tube (inner diameter: the Φ16mm wall thickness: 10mm) vacuum double cone rotary vacuum dryer box exhaust tube (outer diameter: Φ16mm) and vacuum pump (2XZ-2, the inlet diameter Φ16mm) is securely connected ( 6090 and 6210-type connection). Vacuum pump connected to power, began to exhaust, when the vacuum gauge indicates the value of-0.1Mpa, close the vacuum valve and turn off the vacuum pump power to prevent vacuum pump oil to flow back into the working chamber (6090 and 6210 without vacuum valve can be directly off The panel on the vacuum pump power) in a vacuum in the vacuum double cone rotary vacuum dryer machine.
Double cone rotary vacuum dryer debugging:
After commissioning is completed in the degree of vacuum can be used for the following:
a) Turn on the power of the double cone rotary vacuum dryer, the power LED should light (6090 and 6210 shall be respectively open the switch of the temperature control device) temperature controller power-on self-test, the PV screen displays the indoor temperature measurement, the SV-screen display factory-set temperature. Temperature control device on AT & HEAT lamp should be bright, that instrument into the heating state.
Modify the set temperature
About temperature control device, function keys (SET); PV-screen display SP characters can be used to the button head button to set the temperature changes (6090 and 6210 type 2 and 3 meters should be set to modify the following class the same).
2 After editing, click the SET button, the PV-screen display ST characters, set a regular time. If you do not use the timer function, you still let ST = 0
(3) and then click the SET button, the PV-screen display studio temperature, the SV-screen display the set temperature. Instrumentation AT HEAT lights, instrument re-enter the heated state.
(4) double cone rotary vacuum dryer objects in the working chamber humidity, water vapor will affect the vacuum pump performance, it is recommended between the double cone rotary vacuum dryer box and vacuum pumps in series with a double cone rotary vacuum dryer / filter. This demand with a Dimension Φ120 × 300mm, the interface outside diameter Φ16 bipyramid rotation vacuum dryer.
(5) If in the process of double cone rotary vacuum dryer items need to add nitrogen and other inert gas shall be specified in the contract, was equipped with an inlet valve.
b) When the work of the indoor temperature close to the set temperature, the HEAT lamp ignore bright ignore dark, said heating into the PID regulator stage, the instrument is sometimes measured temperature exceeds the set temperature, sometimes below the set temperature is normal. When the measured temperature is close to or equal to the set temperature, and then to be 1 ~ 2h studio into the constant temperature condition, the items into the double cone rotary vacuum dryer stage.
c) the desired temperature is low, we can use the second set way, such as the required operating temperature of 70 ° C, the first first set to 60 ° C, the temperature overshoot began to fall, then the second set 70 ° C, This can reduce or even eliminate the temperature overshoot phenomenon, as soon as possible into the constant temperature.
Items after the double cone rotary vacuum dryer, turn off the power, if the accelerated cooling, the fight to open the valve to the vacuum level until about five minutes to call out of the box door.
Note the use of the double cone rotary vacuum dryer machine:
An enclosure must be effectively grounded to ensure safety.
Two vacuum double cone rotary vacuum dryer machine in the relative humidity ≤ 85% RH, no corrosion around the vacuum dryer sexual gas, no strong vibration source and the existence of a strong electromagnetic field environment.
Vacuum double cone rotary vacuum dryer machine studio explosion-proof, anti-corrosion treatment, shall put Yi Ran, explosive, easy to produce corrosive gases items bipyramid rotation vacuum dryer.
The vacuum pump can not be a long time work, you should close the vacuum valve, so when the vacuum degree of the double cone rotary vacuum dryer items, and then turn off the vacuum pump power until the vacuum is less than the requirements of the double cone rotary vacuum dryer items, and then Open the vacuum valve and vacuum pump power, continue to vacuum, and this may be extended to the vacuum pump service life.
5 double cone rotary vacuum dryer, items such as wet, and the best join between the vacuum tank and vacuum pump filters, to prevent the wet gas into the vacuum, causing the vacuum pump failure.
Double cone rotary vacuum dryer items such as double cone rotary vacuum dryer changed after light weight, small size (small particles), the vacuum in the working chamber members plus the deadening network, to prevent double cone rotary vacuum The dryer inhalation damage to the vacuum pump (or solenoid valve). 7 vacuum double cone rotary vacuum dryer machine after repeated use, will produce not the vacuum phenomenon, and you should replace the door seals or adjust the box on the door buckle stretched distance. Bipyramid rotation vacuum dryer temperature of the vacuum chamber is higher than 200 ° C will produce a slow air leaks (except for 6050,6050 B, 6051,6053 outside), then open the box to double cone rotary vacuum dryer behind cover Allen wrench loosen the heater base, the exchange ring, or tighten the heater base.
8 release valve rubber stopper rotating difficulties can, including a generous amount of grease. (Such as Vaseline)
In addition to maintenance, you can not open the box on the left cover (6090 and 6210) in order to avoid damage to the electrical control system.
10 vacuum double cone rotary vacuum dryer machine should be kept clean. The door glass should not respond to a chemical solution to clean, the application of soft cotton cloth.
11 vacuum double cone rotary vacuum dryer machine unused for long periods, exposed plating wipe painted with neutral grease, to prevent corrosion, and wear a dust cover of plastic film, placed in the double cone rotary vacuum drying machine indoors, to prevent electrical components from moisture damage, affect the use.
