Recently, there are too many gas explosions and various kinds of gas threats to personal safety, which is very important! According to the burning characteristics of gas in the furnace, the safety control requirements mainly include pre blowing, active burning, burning condition monitoring, protection of biomass particle incinerator from ignition, flameout protection, gas pressure bump limit protection , lack of air pressure protection, power-off protection, measures to prevent gas leakage, etc. Let's talk about the safe burning of fuel incinerator:
It is necessary to understand the era of each incinerator. Here is a simple analysis. One. Common faults and cleaning methods of the manipulator: start with 530se, for example, from the analysis of structure and circuit of the manipulator, all the simplest manipulators of 530se liyalu, so the attack faults are small and easy to shoot. Common faults do not fire.
1. How to solve the fire attack? Open the controller shell for the first time, and observe whether the operator's controller equipment and circuit board are burnt. The scorched device is the most common varistor burnt out replacement, another plane resistor wire is burnt. There are frequent burn attacks on the flat wire. Sometimes, as long as the injury is repeated, the manipulator can return to normal. Sometimes, once the injury has been burned, it indicates that the power supply is short circuited and the replacement power tube can recover to normal. Flat wire burned out, power tube damaged about 60% 530se controller repaired.
2 if you are an internal component of the controller and there is no trace of burning on the circuit board, you should check whether the controller is supplied. The 530se control power supply is 3 feet (n) and 5 feet {l} internally connected with 6 feet and 6 feet of motor power. When the motor's electric motor, 50 V communication voltage is controlled by 7 feet, flat wire pair. Therefore, for the first time, the multimeter communicates with 250V documents to measure whether there is 220V at 3 feet (n), 5 feet {l}. If there is no voltage, clarify whether there is a problem with the external power supply, and then measure whether there is 220V at 3 feet (n), 6 feet {l}. If there is no voltage, clarify that there is a problem with the internal contact point, some common problems are poor contact of the touch point, or the contact point is open. The former is only a light leather polish can be plastic contact reed, good contact to. 3. 6 feet high, if there is no ignition, you should check the power control circuit power supply. Use the multimeter's DC 50 V DC voltage output to measure whether the bridge is facing the north and south poles. Common problems usually bridge damage, replacement can recover normal.
4. Zhang Ruo did not ignite to describe the problem of liquid level control circuit and ignition transformer. Because of the low rate of defects, it is not an analysis.
Two. Common faults and cleaning methods of the controller, corrected RIA road conditions:
1. Small power supply voltage regulator;
2. 530se controller base;
3. Internal wiring, RIA method G20, for repair reference test;
4. MF 47multimeter;
5. 30W internal heating soldering iron;
6. It is used to replace frequently damaged components such as power transistor, transistor, diode, zener diode, qiaodui, flat steel wire resistor and varistor;
7. Common toolsets;
