How to maintain the dust-free oven?

Hello, Shenzhen Goldman Sachs Experimental Equipment Co., Ltd. specializes in designing and manufacturing all kinds of experimental equipment, and now provides basic maintenance technology of dust-free oven for your reference. For more detailed parameters or other questions of the dust-free oven, please refer to our website. Website: Dust-free ovens need maintenance after a long time of use, which can be divided into daily maintenance, monthly maintenance and half-year maintenance according to different time. This paper introduces in detail the different maintenance methods of dust-free oven at different times. Daily maintenance of dust-free oven 1. Clean the dust on the surface and cavity, and keep the machine clean and hygienic. 2. Check whether the current of ammeter is the same as the normal value. If there is any abnormality, notify the mechanic for maintenance. In case of sudden power failure, turn off the heating switch to prevent it from starting automatically when the call comes in. Monthly maintenance 1. Check whether the vent is blocked and clean up the accumulated dust. 2. Whether the fan operates normally. 3. The mechanic checks whether the current is normal. Maintenance 1 half a year. Check whether the circuit and switch are normal. 2. Oil the motor gearbox. 3. Whether the mesh belt is tight or not. Dust-free oven instruction manual Dust-free oven operation method (1) Please correctly connect the three-phase power supply, neutral wire and ground wire. (2) Turn on the power switch, the power indicator lights up, and the voltmeter indicates that the voltage is 380 volts. (3) Turn on the air delivery switch. At this time, the gas transmission motor starts to run, and strong wind blows out from the oven liner (please pay attention to the running direction of the gas transmission motor, and the left and right lower edges are blown out by strong wind, which is normal) (4) Turn on the heating switch again, and the instrument shows: 5 seconds self-inspection. After the self-inspection, enter the heating state, and confirm by (5)▲ three keys and SET key. Adjust the required temperature and heat it (heating without running air is strictly prohibited). (6) Set the timer time. The keys 1, 2, 3 and 4 on the panel correspond to the displayed values, 10, 100 and 1000 respectively. Turn on the timer switch after arbitrarily modifying the required time. (7) Description of overtemperature setting: In general, the temperature set by overtemperature should be 3~5℃ higher than that set by thermostat. In case of overtemperature, the overtemperature indicator will light up, all heating systems will be turned off, and the air supply system will operate normally. (8) When the baking time is up, turn off the timer switch, heating switch and air supply switch, and open the door to take out the product. Temperature controller setting: (1) temperature setting: instrument PV shows the actual temperature in the furnace, and SV shows the set temperature. Press the move key first, and the SV display value will flash, then press ▲ to increase the temperature, or press the minus key to decrease the temperature, and finally press the set key to determine the temperature you set, and the SV display value will stop flashing. (2) Power setting: First press the set key 1 sec, PV will display the parameters of OUTL, SV will display the power output of the machine, and the output power of the whole machine can be modified by adjusting this parameter (the amplitude of power modification is the same as that of temperature modification). Troubleshooting of abnormal phenomena in clean oven: 1. Turn on the power switch, which is not displayed on the operation panel? (1) Please check whether the three-phase power supply and neutral wire fall off. (2) Whether the internal switch trips. (3) Whether the fuse is blown, please replace it with a new one. (4) Whether the phase sequences of R, S and T are consistent, please replace the three-phase power supply. 2. No heating/slow heating: (1) Please check whether the output power is set to zero or lower. (2) Please check the three-phase power supply and neutral wire. (3) Whether the air switch is turned on and the direction of the fan is correct. 3 No air source: (1) Please check whether the three-phase power supply and air source contactor are connected and whether the thermal relay is connected. Remarks: 1. The indicator light MAN corresponding to the A/M key on the thermostat is strictly prohibited to be turned on, and it is automatically switched to the manual button. When the MAN indicator light is turned on, the temperature will rise linearly, which is not limited by the set temperature. This dust-free oven belongs to normal temperature oven: baking is strictly prohibited. Flammable and explosive materials. This dust-free oven is safely and correctly grounded. 3. If it is found that there is no blowing air in the dust-free oven, the phase sequence of the power supply should be changed. 4. If it is necessary to time the dust-free oven, adjust the time required for the dust-free oven first, and then turn on the timing switch. Don't turn on the timing switch before the time adjustment, which will lead to timing error. Avoid high temperature when taking out the product! 5. It is forbidden to arbitrarily modify the internal parameters of the thermostat and timer, and the output OUTL parameter of the thermostat cannot be 0.
