Steam electric boiler Introduction:

Steam electric boiler Shanghai zhuanghao electric appliance 15121147052 It is a kind of boiler equipment which takes electric power as energy and converts it into heat energy. After boiler conversion, it outputs steam, high temperature water or organic heat carrier with certain heat energy. It is mainly composed of boiler body, water tube and electric boiler control system. Electric heating mode and electric resistance heating mode of boiler There are three kinds of PTC ceramic semiconductor heating methods. Resistance heating method is divided into stainless steel heating tube electric boiler and ceramic heating tube electric boiler. Resistance heating mode adopts resistance type tubular electric heating element heating, while semiconductor type uses oxide semiconductor ceramic chip, and water and electricity are completely separated. The utility model has the advantages of convenient superposition on boiler structure, high safety coefficient and easy replacement.

Steam electric boiler advantage:  

1.  It is made of thickened boiler steel, 304 stainless steel outsourcing design, through strict ultrasonic testing, head design, durable, using thickened flange, easy maintenance, design power grading control, according to the actual use of steam.

2.  The unique steam water integrated tank and steam water separation structure design are adopted to ensure the rapid supply of high-quality steam with small floor area

3.  It adopts automatic electronic control, automatic adjustment of air pressure and water level, automatic heating and water shortage and overpressure protection, without special personnel on duty. The working mode is flexible and can be set to manual or automatic mode.

4.  The step-by-step control of electric heating elements can reduce the impact of the boiler on the power grid, so as to make the operation of the boiler more stable. The multi-layer insulation with high glass fiber and cotton has the advantages of small heat loss, low energy consumption and high thermal efficiency

5.  The automatic operation time period of the boiler can be set according to the needs, and multiple different working periods can be set in a day to make the boiler automatically time sharing Start each heating group, and the heating group is switched on and off circularly, so that the service time and frequency of each contactor are the same, and the service life of the equipment is prolonged.

6.  It has a complete range of protection functions, such as leakage protection, water shortage protection, grounding protection, steam overpressure protection, over-current protection, power supply protection, etc., and automatic protection of boiler, so as to ensure safe home.

At present, there are two control schemes for steam electric boiler :

1. Industrial control board + input sensor + output driver + communication unit Shanghai zhuanghao electric appliance 15121147052

Industrial control board includes industrial computer class, single board computer, PLC, integrated HMI + PLC control mode to achieve, stable and reliable advantages, can quickly build software, flexible configuration, rapid development speed, high cost shortcomings. Input sensor is divided into analog quantity and digital quantity. Analog quantity has digital type and analog type. Digital quantity is mainly high and low two digit signals. There are two kinds of output drivers: transistor and relay output. The transistor is small in size, but the heat sink is not small, there is no electric shock and wear, no sound. It can be PWM output, which is too expensive. The relay output is divided into signal point and power output (contactor). The communication unit (RTU) is divided into short-range (WiFi / Blue / ZigBee / LORA), remote mobile operator (3 / 4 / 5G), and similar power wireless private network.

2. Shanghai zhuanghao electric appliance 15121147052 microprocessor (arm / DSP / MCU) + HMI panel + peripheral IO input / output + communication unit. The whole components are all made on one circuit board, and the cost is lower. It is suitable for small household electric boilers, peninsula electric boilers, electromagnetic electric boilers and other products which are sensitive to the cost. The above control schemes have automatic control functions such as high and low water temperature control, water level and water flow control, water supply and return water temperature detection, water shortage protection, over temperature protection, pressure protection, multi section timing control, auxiliary functions, leakage protection, door opening protection, power call restart protection, etc. Shanghai zhuanghao electric appliance 15121147052
