The electric blast drying oven is used for drying, baking, waxing and sterilization of industrial and mining enterprises, laboratories and scientific research units . Yashilin (YASHILIN) instrument equipment adopts domestic ling first technology microcomputer intelligent temperature control system with temperature control protection, accurate and reliable. The working temperature is arbitrarily set, and has a deviation alarm function. The air inlet switch is freely open, and the hot air circulation is listed.
Electric blast drying oven maintenance manual
1. Explosive, flammable and volatile materials should not be placed in the dry box to avoid explosion.
2. The average load of the sample shelf should not exceed 20kg.
3. Items cannot be placed on the shelf between the sample chamber and the heating chamber to avoid affecting heat exchange.
4. Be sure to check the nickel wire for overlap and short circuit before use.
5. The heating indicator does not light, there are generally three reasons: 1 the bulb is broken; 2 the bulb is in poor contact; 3 the heating system is faulty.
6. Turn on the heating switch and do not heat it. There are generally four reasons: 1 nickel-chromium wire breaking; 2 switch and line desoldering; 3 temperature control knob refers to zero position (rotation temperature control knob to the specified temperature scale); 4 relay damage.
7. Temperature control failure, the general reasons are three: 1 temperature probe damage (replacement of thermistor); 2 relay damage; 3 other components of the temperature control system failure (using a universal meter to detect the fault, repair according to circumstances).
Electric blast drying oven maintenance manual II
1. The use of the instrument must be handled by a special person. When the equipment is used, the external power supply should be cut off to avoid accidents.
2. When placing the sample in the working room, it should not be too dense, so as not to affect the normal flow of the airflow in the working room. There must be a gap of 10~20mm between each item, and it should be placed symmetrically. The items on each shelf should be staggered. The distance between the bottom shelf and the bottom of the studio must be greater than 100 mm.
3. A certain space should be left around the equipment to facilitate heat dissipation and operation and maintenance.
4. Prevent sharp and sharp objects from scratching the device.
5. Do not disassemble the electrical components and the zero parts of the equipment at will, so as not to damage the electrical control circuit, causing human error of the equipment and affecting its performance.
6. When storing and using the equipment, there are no flammable, explosive and corrosive substances around.
7. Do not put flammable, explosive and volatile materials into the equipment for drying.
8. Please read the “Electric blast drying oven product manual†of Yashilin equipment before using the equipment, and then carry out various operations. Daily maintenance and maintenance of electric blast drying oven
