In the boiler market, the electric hot water boiler produced by FANGKUAI Boiler has been widely loved by customers because of its obvious advantages such as no pollution, no noise, simple operation, and can be used as the main heat source equipment for heating supply. Many users may encounter sudden failures such as water shortage or over-pressure in boilers when using electric hot water boilers. Understand several common faults and troubleshooting methods of electric hot water boilers, solve problems in a timely and rapid manner, and effectively avoid major losses.
1. Boiler water shortage
Serious shortage of water in the boiler can cause deformation and damage of the pressure components. If it is handled improperly, a boiler explosion accident may occur. When it is found that the boiler is short of water, it is strictly forbidden to enter the water and take emergency shutdown measures. The causes of boiler water shortage accidents are mostly related to the slack and paralysis of the operating personnel, or to the blockage failure caused by the flushing of the water level gauge.
2. Steam and water boiling together
When steam and water boiling occurs, the following phenomena are accompanied: the water level of the water level table fluctuates drastically, the water bubbles produced in the pot, the steam carries a large amount of water, the temperature of the steam decreases, and water shock occurs in the pipeline when it is serious. The main reasons for this kind of situation are: poor water quality, too high salt content or excessive boiler load increase. When the user discovers the phenomenon of steam-water boiling, it is necessary to strengthen the water treatment and increase the continuous sewage discharge.
3. Boiler over-pressure
When the boiler is over-pressured, it will cause deformation of the components and damage to the joints; in severe cases, it will cause an explosion accident.
The main reason for this kind of situation is that the boiler personnel blindly increase the working pressure or leave the job. Sometimes, the simultaneous failure of the pressure gauge and the safety valve can cause the boiler to overpressure. Therefore, it is necessary to strengthen the inspection of the responsibility system for the furnace workers and the various safety accessories.
4. Furnace tube explosion
When the furnace tube is exploded, it is accompanied by significant blasting sound and steaming sound; at the same time, the water level and steam pressure will decrease. When this situation is discovered, emergency shutdown measures must be taken.
The general reason for this is that the poor water quality causes scaling or corrosion on the furnace tube, and water shortage and bursting may also cause each other. In addition, due to design defects, insufficient material strength or poor welding quality, it is possible to cause a pipe burst accident.
