The basic requirements of laboratory furnace installation instructions and performance purposes1 is connected to the controller and the experimental furnace power cord, switch and fuse the load capacity of the furnace should be slightly larger than the rated power.Two experimental furnace without special installation, just flat on the interior floor or stand. Controller should be on the table, the work surface should not exceed 5 degrees tilt the controller from the experimental furnace minimum distance of not less than 0.5 m. Controllers should not be placed above the experimental furnace, so as not to affect the controller is working properly.3 wiring, first loosen the screws on both sides around the controller enclosure, and then turn on the cover. Controllers and electric furnace and thermocouple cable connection (best to use compensation wire) would thermocouple from thermocouple hole in the insert holder furnace, the gap between the hole and the thermoelectric clogged with asbestos rope, and then fixed.4 In order to check the burnout protection device is working properly, the method is: Loosen the thermocouple end, when temperature rose rapidly to the highest point instructions also automatically cut off the heating power, the burnout means good, good reconnected thermocouple , it can work properly.5 Check the wiring is correct can be energized, the first on the power switch, and then the experimental furnace controller toggle switch on the front panel to pull the open position, adjust the Settings button, set the temperature to the degree you need , if the set switch to pull the measuring position, the red light is off (NO), the contactor also pull sound, laboratory furnace is energized, the heating current ammeter indicates the temperature slowly rises with increase in temperature in the furnace, indicating that working properly.Laboratory furnace performance summary and use instructionsShell surface made of high quality cold rolled steel, high temperature materials coated, clean, anti-corrosion, anti-smoke, easy to clean, clean, non-toxic breath while hob surface non-stick coating, may also be baked. It has a fast heating, easy to use, high thermal efficiency, particularly safe, durable and so on. Laboratory furnace basic performance, more accurately speaking, the number of laboratory furnace is a closed furnace, however, has its own according to the actual needs of its unique properties, the use of laboratory furnace is converted to heat energy with the principles, the tube furnace heating body is fully enclosed in high temperature insulation material.The main purpose laboratory furnace is based on a closed laboratory furnace above analysis of the advantages, but also through the practice of verification, which is widely used in major schools, industrial and mining enterprises, environmental protection, hospitals, laboratories and scientific research laboratories and other units , one of the necessary equipment is commonly used, but also the ideal home heating appliances.
