An electric heating steam generator is a miniature boiler that automatically and continuously produces high pressure steam, powered by electricity, noise -free and pollution-free. It uses high-quality heating tubes, has a low surface heat load, high thermal efficiency, and is easy to install and maintain. It can provide the necessary dry steam for industrial steam irons and steam ironing machines. According to the Pot Code, a water capacity of less than 30Kg or a pressure of 0.09MPa or less does not require installation notification and supervision inspection(2)Working Principle Of The Electric Steam GeneratorThe electric steam generator mainly consists of the water supply system, the automatic control system, the furnace and heating system, and the safety protection system, etc. The basic working principle is: through a set of automatic control devices, it ensures that the liquid control or high, medium, and low electrode probe feedback controls the opening and closing of the water pump during operation; The maximum steam pressure is set by the pressure controller. As steam is continuously output, the water level in the furnace keeps dropping. When it is at the low or medium water level, the water pump automatically replenishes water. When it reaches the high water level, the water pump stops replenishing water. At the same time, the electric heating tubes in the furnace continue to heat up and generate steam continuously, and the pointer pressure gauge at the top shows the steam pressure value immediately, and the entire process can be automatically displayed by the indicator light.(3)The Function Of The Electric Steam Generator1. Abnormal power protection function of the electric steam generator: The boiler stops running immediately. 2. Electric steam generator leakage protection function: The control system will automatically cut off the power supply when it detects leakage of the electric heating element. 3. Electric steam generator water shortage protection: When the boiler is short of water, the control circuit of the heating tube is cut off in time to prevent the heating tube from being damaged by dry burning, and at the same time the controller issues a water shortage alarm indication. 4. Electric steam generator power supply anomaly protection function: The boiler stops running immediately. (4)Feature Of The Electric Steam Generator1.

Introduction to the desigh,production and use of electric steam generator1. Safety in design, production and use 1 Leakage protection: When leakage occurs in the boiler, the power supply is cut off in time through the leakage circuit breaker to ensure personal safety.2 Water shortage protection: When the boiler is short of water, the heating tube control circuit is cut off in time to prevent the heating tube from being damaged by dry burning, and at the same time the controller issues a water shortage alarm indication.3 Grounding protection: When the boiler shell is electrified, the leakage current is conducted to the ground through the grounding wire to ensure personal safety. Usually protect the grounding wire A good metallic connection with the ground is often used, with Angle iron or steel pipe buried deep underground as the grounding body, and the grounding resistance shall not be greater than 4Ω.4 Steam overpressure protection: When the steam pressure of the boiler exceeds the set upper limit pressure, the safety valve activates and releases steam to reduce the pressure.5 Overcurrent protection: When the boiler operates under overload (excessively high voltage), the leakage circuit breaker automatically trips. 6 Power protection: With the aid of advanced electronic circuits, reliable power-off protection is provided after detecting fault conditions such as overvoltage, undervoltage, and phase loss. 2. Ease of use1 After the power is introduced into the electrical control box, with a single button operation, the boiler enters (or disengages) the fully automatic operation state. 2 When the water volume in the boiler decreases, the control system automatically replenishes water from the water tank to the boiler through the make-up water pump. 3. Rationality of the designIn order to use electricity reasonably and effectively, the heating power is specially divided into several segments and automatically cycled on (off) by the controller. After the user determines the heating power according to actual needs, they only need to close the corresponding leakage circuit breaker (or press the corresponding on -off switch). The segmented and cyclic switching of the heating tubes reduces the impact of the boiler on the power grid during operation.4. Reliability in use 1 The boiler body uses argon arc welding for the base, manual welding for the cover, and has undergone strict X-ray flaw detection.2 The steel used in the boiler is selected strictly in accordance with the manufacturing standards.3 The accessories used in the boiler are selected from high-quality domestic and foreign products and have been tested in the furnace to ensure the long-term normal operation of the boiler. 3. Part names and main components of the electric steam generator1). Part names2). Description of main components1 Water level gauge alarm and water level gauge: The water level gauge is a direct observation point for displaying the internal water level of the boiler. The internal water electrode is an important safety accessory for indicating the normal operation of the burner and water pump. Currently, our company commonly uses two types of water level gauges: plate level gauges and black and white level gauges. When there are impurities in the water level gauge that make it difficult to see the water level or affect the water level action, please open the cleaning valve and clean the water level gauge in a timely manner. Attention: The reliability of this simple component largely determines the safe and reliable operation of the boiler.
