Operation manual of table air blast drying oven

1、 Use: electric constant temperature blast drying oven is used for various tests and production sites in laboratories and laboratories of scientific research units, professional colleges, industrial and mining enterprises, etc., such as drying, curing, baking, wax melting, disinfection and other applications II Cold rolled steel plate is used for the structure box body, with electrostatic powder coating on the surface, hard and firm coating, and strong rust resistance The working room is made of stainless steel plate, with round corner shape, smooth, smooth and easy to clean Between the box and the working room, filled with ultra-fine glass wool thermal insulation material, with good thermal insulation function, effectively ensuring the stability and accuracy of the box temperature and the impact on the use environment The observation window of the box door is of double-layer toughened glass structure, which can clearly observe the heated items in the box and has good heat insulation effect A reasonable hot air circulation channel is designed in the box to make the temperature distribution more uniform and the temperature rise faster An adjustable air outlet pipe is installed to regulate the air in and out of the box If the gas discharged from the box has peculiar smell or is poisonous, the air outlet pipe can be connected with another pipe to discharge the gas to the designated place conveniently The temperature control is made of microcomputer intelligent digital technology, with industrial PID self-tuning and four position double led window indication function, high temperature control accuracy, strong anti-interference ability, and very convenient operation (see the operation manual of the temperature controller for details) III technical parameters model power supply voltage temperature control range temperature fluctuation Tracking Alarm consumption power studio size (mm) dhg-9013a 220V 50Hz 50 ℃ ~ 250 ℃ ± 1 ℃ + 5 ℃ 300W 250 * 250 * 250 dhg-9053a 800W 345 * 415 * 370 dhg-9123a 1500W 524 * 554 * 370 dhg-9203a 2000W 600 * 600 * 500 4、 Product installation and debugging 1 Do not use force on the glass or collide with the box during transportation 2 After landing, the equipment shall be placed stably and corrected if the ground is uneven 3 Please do not use the instrument in direct sunlight or high temperature and humidity 4 The equipment shall be far away from electromagnetic interference source, and the grounding wire of the equipment shall be effectively grounded 5 During normal operation of the equipment, the contents in the box shall not affect the air circulation to ensure the temperature in the box is uniform 6 The power supply is AC 220V 50Hz, three core socket above 16A must be used, with reliable grounding wire, and two core socket is not allowed to be used without permission 7 The power cord shall not be close to the back, and the instrument or other articles shall not be pressed on the power cord to avoid damaging the power cord V product instructions 1 Open the box door, put the items to be processed on the shelf in the box, and close the box door 2 Connect the power supply, insert the three core plug into the power socket, and set the power switch on the right side of the panel to the "on" position At this time, the digital display appears on the instrument, indicating that the equipment is in working state 3 Set the required temperature in the cabinet by operating the temperature controller on the control panel 4 The instrument starts to work, and the temperature in the box gradually reaches the set value After the required drying treatment time, the treatment is completed 5 Turn off the power supply When the temperature in the box is close to the ambient temperature, open the box door and take out the object [! 】Please note: pay attention to the temperature in the box when opening the door to take things, so as to avoid scalding ◆ special tips (1) Products are strictly tested before leaving the factory, and generally do not need to be corrected If the environment is harsh and the ambient temperature is out of the appropriate range, the temperature display value and the actual temperature in the box will be caused If it is out of the range of technical indicators, it can be corrected according to the operation instructions of the temperature controller as required (2) under normal working conditions, if the door is opened for too long, the temperature in the box will change temporarily after the door is closed, which is a normal phenomenon (3) test note: the thermometer used in the box test shall be a 0.1 precision mercury thermometer, and the mercury end shall be placed in the geometric center of the box 6 Precautions 1 Flammable and volatile chemicals shall not be put into the box 2 In case of any abnormality, smell, smoke, etc during the use, please turn off the power supply immediately The user shall not repair blindly, but inform the repair Department of the company, and the professional shall check and repair 3 The inner tank of the box wall and the surface of the equipment shall be wiped frequently to keep clean and increase the transparency of the glass Do not wipe the outer surface with acid, alkali or other corrosive solution 4 If the equipment is not used for a long time, unplug the power cord to prevent the equipment from damaging people The company is located in Daoxu Town, Shangyu District, Shaoxing City, Zhejiang Province It is an enterprise integrating production, product research and development, processing and trade The company's main products: drying box series, incubator series, laboratory muffle furnace series, distiller series, as well as clean workbench, air shower room, ventilation cabinet, biosafety cabinet and other complete sets of purification equipment The company has a strong technical research and development team, a strong after-sales service system, is the leading manufacturer of complete set of laboratory equipment in China, welcome customers to buy.
