Characteristics of electric water heaters Types of electric water heaters

Electric water boiler, also known as electric water boiler, is a kind of drinking water equipment designed and developed to meet the needs of more people to drink boiled water, which uses electric energy to convert into heat energy to produce boiled water. Do you know the characteristics of electric water heaters? What types are there? Today, Bian Xiao will talk about the characteristics of electric water heaters.

Types and characteristics of electric water heaters

1.KS-D continuous electric water boiler

1, advanced ceramic electric heating tube and high-quality seamless steel tube are adopted, which can effectively prevent scale interference and have long service life. The heat absorption structure is optimized by computer, and the heat transfer coefficient of the heating surface is completely optimized, and the thermal efficiency is extremely high, reaching more than 98%. Greatly reducing the power loss.

2. The boiling water boiler is equipped with a computer controller, and the operation of the boiler is intelligent, digital, automatic and humanized. The water temperature from 10℃ to 100℃ can be set at will, and the boiler can supply both boiled water and hot water, so as to realize the dual purpose of one machine.

3, the boiler intelligently controls the water temperature, the boiler boils water, and the heating automatically stops; The water temperature is displayed on the screen of the controller in large font, and a glass tube water level gauge is equipped outside to make the boiler water temperature and water level clear at a glance.

4. The boiler is designed as an atmospheric furnace, with vent holes at the top of the furnace body, and the boiler is in a pressureless state, so there is no potential safety hazard. Users can set the switching time by themselves according to the water demand, which not only meets the requirements of users, but also saves energy and reduces the use cost.

5. After the boiler is filled with water, the water filling will stop automatically, saving time, trouble, effort and effort.

6. The reliable "water-electricity separation" structure of the boiler can prevent the potential safety hazard caused by accidental leakage of electric heating pipes to users and workers, and at the same time, it can repair, replace and maintain the heating parts of the boiler without draining water.

7. Choose high-precision water level sensor to monitor the water level in real time. The sensor uses pulse intermittent detection to judge whether the water level in the boiler is normal or not. When the outlet water temperature reaches boiling water, the boiler will automatically fill up the water one after another, and the boiler can continuously supply 100% fresh boiling water.

8. At the same time, the whole machine is equipped with overheating protection (when the water temperature in the boiler is too high, the burner will automatically stop working and give a buzzer alarm), secondary overheating protection (when the boiler shell temperature exceeds 105℃, the secondary circuit will be automatically cut off), dry burning water shortage protection (when the boiler water is lower than the extremely low water level, the boiler stops working and gives a buzzer alarm), and boiler leakage protection (after the control system detects leakage and short circuit)

9. The outer packaging is made of aluminum foil, centrifugal glass wool multilayer insulation and famous white color steel plate, which has less heat loss, beautiful appearance and rust prevention.

Second, the sub-cabin electric water heater

1. This equipment is a fully automatic digital energy-saving drinking water equipment carefully designed and manufactured to meet the requirements of more people to drink boiled water. It converts electric energy into heat energy, heats water and stores it in a boiling water tank, thus continuously supplying a large amount of boiled water.

2. The top of the furnace body is provided with an exhaust port communicating with the atmosphere, and the inner container is not pressurized. The boiler works under normal pressure, so there is no explosion danger, and the potential safety hazard is completely eliminated. Centrifugal aluminum foil glass wool felt seals the boiler for heat preservation, and the boiler water is slowly cooled.

3. Equipped with a boiler controller with a computer as the core, all functions are magically stored on an intelligent chip with a microprocessor like a mobile phone, and the logical tree structure with intelligent characteristics makes the boiler function very complete.

4. Industrial wide temperature LCD. Built-in backlight can clearly display the day and night operation of the boiler: boiler outlet temperature, 3-digit display (5℃-100℃); Boiler water level, 5-level water column height simulation display and Chinese display; The working state of ceramic electric heating tube and water replenishing solenoid valve is displayed by graphic animation; Automatic/manual status of the water replenishing solenoid valve with graphic display; Real-time clock and digital display; 6 working states of boiler (set state, running state and 4 timing states), displayed in Chinese; 6 alarm messages (dry-burning prevention and water shortage alarm, water temperature ultra-high alarm, temperature sensor fault alarm, ceramic electric heating tube fault alarm, water level sensor fault alarm, controller ambient temperature ultra-high alarm (controller internal temperature exceeds 60℃), displayed in Chinese and code; Electric heating tube cumulative time of boiler, digital display.

5, boiler water temperature control; Water level control of boiler or water tank; According to the preset four time periods, the boiler automatically starts and stops; Electric heating tube start-stop and power automatic control; Automatic/manual control of water replenishing solenoid valve; Six alarms (anti-dry-burning water shortage alarm, ultra-high water temperature alarm, temperature sensor fault alarm, ceramic electric heating tube fault alarm, water level sensor fault alarm, controller ambient temperature ultra-high alarm (controller internal temperature exceeds 60℃) are interlocked and controlled.

6, cutting-edge computer microprocessor, only through simple operation and setting, the controller will give full play to the boiler control function in the form of words, graphics or animation.

7. The bottom of the boiler is provided with a water supply (water inlet) port, which solves the disadvantage of "yin and yang water" caused by the mixing of cold water and boiling water caused by floating ball water supply at the top of the traditional boiling water boiler. The boiling water bin and the heating bin are completely separated, and the cold water automatically overflows from the heating bin after boiling. The high-sensitivity water level probe monitors the water level until the boiling water bin is full, which can be used as disposable fresh water for users to drink, and there is no "thousand boiling water" phenomenon of repeated boiling water. The residual heat of the heating chamber can be used for long-term energy saving and heat preservation, and the boiling water chamber can supply high-temperature boiling water as usual after staying overnight. The double liner design of the boiling water tank and the heating tank can meet the user's demand for a large amount of concentrated water during peak hours without adding another warm boiling water tank.

8. The boiling water port is set at the upper part of the temperature sensing probe to monitor the temperature. The water temperature of the boiler is set at 96℃- 100℃, so the water outlet temperature of the boiling water port will definitely be greater than or equal to the set temperature, completely realizing the consistency between the temperature displayed by the controller and the actual water outlet temperature of the boiling water port.

9. The seamless steel pipe on the ceramic electric heating pipe cover heats water, and the ceramic is insulated from the steel pipe. The steel tube completely isolates the ceramic electric heating tube from the boiler water, forming an electric heating mode of "separation of water and electricity". The heating pipe is not affected by scale, which not only prolongs the service life, but also facilitates the maintenance and replacement of the heating pipe and greatly improves the safety factor.

10, equipped with leakage circuit breaker, time delay relay, fuse, AC contactor, overheat protector and other electrical components. The boiler has multiple protection functions, such as electric leakage, short circuit, overload, overvoltage, undervoltage, overheating and imbalance, to ensure the safety of use.

1 1. The perfect combination of boiler body and supporting electrical appliances realizes the electromechanical integration of boiler, which not only effectively saves installation space, but also facilitates installation and transportation.
