Introduction to electric boiling water boilers

Electric boiling water boilers mainly include KS-D continuous electric boiling water boilers and subdivided electric boiling water boilers. The main components of electric boiling water boilers are used for heating. For electric heating tubes, it is best to choose water-electricity separated ceramic electric heating tubes with insulating materials. This kind of heating tube has a high safety factor and a long service life. Under normal circumstances, it can generally work for 6-7 years. Electric water boilers are not special equipment boilers. The design, manufacture, installation and use of electric water boilers do not require the supervision of the technical supervision department, nor do they need to apply for a boiler usage certificate.

Classification of electric water boilers

According to different heating tubes, electric water boilers can be divided into stainless steel electric heating tube water boilers and ceramic electric heating tube water boilers. Stainless steel electric heating tube water boilers are also called immersion heating electric water boilers. The heating tubes of this type of water boiling furnace are susceptible to interference from scale, causing tube bursts and leakage, which are both unsafe and have a short service life. Ceramic electric heating tube water boilers are also called water and electricity separated type. Electric water boiler, the heating tube of this water boiler does not come into direct contact with the water, the structure is relatively reasonable, and it is safe and has a long service life.

According to different water supply methods, electric boiling water boilers can be divided into KS-D continuous electric boiling water boilers, XKS-D regenerative electric boiling water boilers, KS-D continuous electric boiling water boilers and sub-chamber electric boiling water boilers. furnace. KS-D continuous electric boiling water boiler directly supplies boiling water or is connected to an insulated water tank to continuously supply boiling water; The cabin-type electric boiling water boiler has two water tanks, the boiling water tank and the heating tank. The boiling water tank and the heating tank are completely separated. After the cold water is boiled, it automatically overflows from the heating tank into the boiling water tank. A high-sensitivity water level probe monitors and controls the water level. Until the boiling water tank is full, it can be used as one-time fresh boiling water for users to drink. There is no "thousand boiling water" phenomenon of repeatedly boiling water. And it can use the waste heat of the heating cabin to save energy and keep heat for a long time. The boiling water cabin can continue to supply high-temperature boiling water after leaving it overnight.

Continuous electric water boilers

1. Operation mode

1. Continuous electric water boilers work alone

When using a continuous electric water boiler for the first time, you need to press and hold the "manual start and stop" button of the controller to force the boiler to add water. When the water level reaches the extremely low safe water level, the boiler automatically stops replenishing water, and the microcomputer boiler controller passes After setting, the boiler starts to work fully automatically, automatically replenishes water, and automatically heats. When the set temperature is reached, the boiler enters the automatic heat preservation state and begins to continuously supply boiling water to the user.

2. The electric water boiler is connected to the insulated water tank to work

First fill the boiler with tap water, then start the electric heating pipe to start heating. After the boiler water reaches the set temperature (boiling water), control The solenoid valve for boiler water inlet opens, and tap water enters the boiler from the lower part of the boiler, thereby pushing the boiling water from the water outlet on the upper part of the boiler into the insulated water tank. The insulated water tank is connected to the boiled water pipe to meet the centralized water demand. In addition, a water temperature control probe is installed on the top of the insulated water tank. It will automatically replenish water when it is lower than the set water level.

Precautions for using electric water boilers

1. Descale the furnace body regularly. The thermal conductivity of scale is extremely low. Once there is a large amount of scale in the furnace body, not only the power consumption will be greatly increased. , and it is easy to cause the water level control probe and temperature probe to malfunction.

2. Regularly check the water level control probe and temperature sensing probe. Failure of the water level probe will cause the boiler to "fake dry burning" or the boiler will emit water through the atmospheric port; failure of the temperature sensing probe will cause the water temperature to rise. Inaccuracy or non-stopping.

3. Clean the water inlet solenoid valve regularly. If there are foreign objects in the solenoid valve, there will be a phenomenon of mixing of the inlet water and cold boiled water during a power outage, and water will come out of the boiler's air vent.

4. When descaling, you should first unscrew the plug of the descaling hole and add the descaling agent through the descaling hole. Adding the descaling agent from other places will not work because there is only the descaling hole. It leads directly to the heating cabin.

Maintenance

1. Frequently check whether the electrode that controls the water level is sensitive, and clean the probe of the water level electrode regularly.

2. If the continuous electric water boiler is connected to an insulated water tank, it is necessary to regularly check whether the water outlet pipe from the boiler to the water tank is blocked.

3. Add medicine and descale the boiling water boiler regularly.
