Parts of vacuum drying equipment electric heating constant temperature blast drying oven

1. Built-in circulating air duct and fan;

 

  2. The temperature controller can be selected as an intelligent program temperature controller;

 

  3. Air conditioning method of blast drying box: forced internal circulation ventilation, balanced temperature adjustment;

 

  4. The outer shell of the drying box is made of cold-rolled plate, the surface is sprayed with plastic, the shape is beautiful, and the thickness is moderate;

 

  5. The blast drying oven adopts a microcomputer temperature controller with digital display and temperature control protection, and has a timing function;

 

  6. Hot air circulation system: It is composed of fans that can run continuously at high temperature and suitable air ducts to ensure uniform temperature in the working room

 

  7. The inner liner of the box is made of mirror stainless steel (or wire drawing board) by argon arc welding. It is equipped with a two-layer shelf with adjustable height, which is convenient for shelving samples;

 

  8. The electrical control system has over-temperature protection function, and the digital display microcomputer P.I.D temperature controller has timing function;

7 principles for maintenance of vertical blast drying oven for vacuum drying equipment:

1. You must pass the professional, safety, and technical training for this type of work, pass the examination, and obtain the operation qualification certificate before you can take up the job with the certificate.

2. This box is a non-explosion-proof drying box. Do not put flammable and volatile items into the drying box.

3. The average load of the test product shelf is 15 kg. When placing the test product, it should not be overloaded or too dense. At the same time, the test product and other things cannot be placed on the heat sink.

4. Before use, check the installation position of each heating wire of the heater to prevent the heating wire from overlapping or colliding.

5. Before power-on, check the electrical performance of the vertical blast drying box, and pay attention to whether there is an open circuit and leakage, and unscrew the exhaust valve on the top of the box, and the gap is about 10mm.

6. After the power is turned on, turn the temperature control knob to the desired temperature, the temperature measurement indicator light is on, the temperature begins to rise, and the blower can be turned on at the same time, and pay attention to whether the blower is running normally.

7. When the temperature rises to the predetermined temperature, the constant temperature indicator light is on, and the temperature controller automatically controls the temperature. At this time, put the test sample and close the door of the box, and start the drying of the sample.
