With the advancement of our country's market economy, civil technology and craftsmanship have also advanced, in most industrial and mining enterprises, medical schools, scientific research units from time to time to dry to deal with some of the composition of the particularly complex items, so the corresponding electric constant temperature vacuum drying oven has become an indispensable drying tool. However, for most of the non-relevant industries or people who are about to enter the corresponding industry for this type of drying box but lack of corresponding understanding, and even unclear of the basic operating procedures, the following let the rabbit to solve the puzzle for you one by one, and introduces the basic knowledge of the drying box.
Basic introduction:
Electrothermal constant-temperature vacuum drying oven is designed for drying heat-sensitive, easy to decompose and oxidizable substances and design, at the same time in the work of the chamber to maintain a certain degree of vacuum, and can be filled with inert gas to the interior, especially some of the complex composition of the goods can be rapid drying. It is a modern drying tool which adopts intelligent digital temperature regulator to set, display and control the temperature. At present, it is widely used in biochemistry, chemical and pharmaceutical industry, medical and health care, agricultural research, environmental protection and other research and application fields.
Features:
1, the shell adopts electrostatic spraying technology, paint film is stable and reliable;
2, can choose a variety of temperature control instrument, high precision temperature control, good stability;
3, the box door adopts silicone sealing, good sealing effect.
Operation process:
1, the box is placed in a dry and horizontal indoor, do not need to use other fixed devices.
2, should be installed in the power supply line, an iron shell gate switch for this box dedicated, and use than the power line twice as thick as the wire for the grounding wire and effective grounding.
3, before energizing, first check whether the voltage of this box is consistent, and according to the total work rate converted to the current size, connected to the corresponding specifications of the power cord.
4, when everything is ready, can be put into the test product, close the door, then you can connect the power supply, start working.
5, you can not arbitrarily remove the side door, together chaos or change the line, only when the box failure can remove the side door, according to the line check one by one. If there is a major failure, you can contact the factory and maintenance point.
6, connected to the power supply can open the power heating switch, when the required temperature is higher than 150 ℃ can be opened to high temperature gear. Otherwise do not have to open the high temperature, only the power supply file on the line, and then the thermostat knob from the "O" position clockwise direction to the desired temperature point, at this time the box began to heat up, the instrument green light for instructions. At the same time you can open the blower switch, so that the blower began to work.
7, the temperature rises to the required working temperature when the green light off red light, in this indicator alternately bright and clear that is the constant temperature point. (In the constant temperature point when the temperature is likely to continue to rise, this is the effect of residual heat, about half an hour after the stabilization), when the indoor temperature stabilization, 101A, 202A type red digital display, readings beyond or below the required temperature, you can adjust the knob slightly to achieve the correct degree.
8, the temperature of the constant temperature, according to the test needs, make it for a certain period of time for the constant temperature. In this process, can borrow the box thermostat automatic temperature control, without manual management.
9, want to observe the studio specimen situation, you can open the door of the box, borrow a glass door or observation door to observe the box. But the box door to infrequently open as appropriate, so as not to affect the constant temperature, and when the temperature rises to 300 ℃, open the box door may make the glass door rupture of the rapid cooling.
10, the user to use the box, please read the instrumentation manual.
11, the new box should be used when the humidity may appear hot evaporation and paint smell, this is the thermostatic paint surface volatilization caused by the use of an hour will disappear.
In addition to understanding the basic situation of the drying box, and the operation process, we also need to pay attention to the drying box in the daily use of maintenance. Especially in order to avoid the circuit burned, in the use of the drying box before the time to check whether the power supply voltage with the rated voltage of the box in line with the electric constant temperature drying box has a thermostat and other electronic equipment, so can not be the box to the corrosive environment containing acid or alkali. In addition, it is worth mentioning that volatile objects and flammable and explosive substances cut can not be put into the drying box, otherwise it is easy to cause an explosion, after all, safety first. Electric constant temperature drying box is introduced here, I hope to be able to help you.
