Ronghua ZK series electric vacuum Drying Oven instruction manual

structure

The shell of ZK series vacuum Drying Oven is made of cold-rolled steel plate, the working chamber is made of ordinary cold-rolled steel plate or stainless steel plate, and rock wool insulation material is filled between the shell and the working room. The electric heating element of Zk series vacuum Drying Oven is installed under the working room, and there are air inlet, suction hole, vacuum valve and other components in the lower left corner.

temperature control method

1. Pointer-type electronic temperature control instrument, the main circuit of the electrical appliance is equipped with a contactor to automatically control the temperature of the drying box and indicate the temperature automatically.

2. Digital display temperature control instrument, the main circuit of the electrical appliance is equipped with a contactor or a thyristor non-contact switch to automatically control the temperature of the drying box or connect to a PID precision control, and the temperature in the box is automatically displayed.

3. Dual-display AI artificial intelligence temperature control instrument, the main circuit of the electrical appliance is equipped with a thyristor non-contact switch, or a thyristor power output module, and performs precise artificial intelligence control on the temperature of the Drying Oven <high ​​precision level>

4. Dual-display AI artificial intelligence program temperature control instrument, the main circuit of the electrical appliance is equipped with a thyristor non-contact switch or a thyristor power output module to control the temperature of the drying box with an artificial intelligence program, and the heating speed and holding time can be set according to The prepared process temperature curve runs automatically <high ​​temperature control accuracy and high automation level>

Instructions for use

1. Open the packing box and check whether the vacuum drying box is intact. When connecting the power line, the user needs to install a power isolation switch to control the total power supply.

2. The power supply voltage is single-phase 220V, and the shell of the vacuum box must be reliably grounded.

3. After checking that the wiring is correct, turn on the main power supply, turn on the power switch, turn on the Vacuum Pump and open the suction valve to wait for the working room. When the pressure is less than 260Pa, turn on the heating power switch and set the temperature controller to the required temperature. <The program control instrument inputs the program process curve into the instrument>, at this time the green light of the instrument is on, (the main output light of the smart instrument OTV is on), the vacuum box starts to heat up, and the instrument shows that the temperature rises and the vacuum box is working normally.

4. When the new oven heats up for the first time, there will be turbid gas discharged from the oven. This is because the heat-resistant silver paint on the four walls of the oven and the supporting plate is not dry before leaving the factory. After the gas [smoke] is exhausted, it will not affect the use. .

5. If you choose a Drying Oven controlled by AI artificial intelligence, please read the instrument manual in detail. Master the use of self-tuning.

Precautions

1. The user should read the instruction manual in detail before using the operation to understand the usage method and precautions.

2. The box should be equipped with a special knife switch, and the equipment shell should be reliably grounded.

3. It is advisable to equip the vacuum Drying Oven with 2XZ-2 Vacuum Pump.

4. This vacuum Drying Oven is not suitable for use under non-vacuum conditions and vacuum drying of flammable and explosive materials.

5. There should be special personnel to operate and monitor regularly, and the instrument should be overhauled once a year.

6. Do not touch the sight glass during the working process of this vacuum Drying Oven to prevent burns.
