The Main Structure Of An Electric Steam Generator

The electric heating steam generator mainly consists of a water supply system, an automatic control system, a furnace liner and heating system, and a safety protection system.
1. The water supply system is the throat of a fully automatic steam generator, continuously supplying users with dry steam. After the water source enters the water tank, turn on the power switch. Driven by the self-control signal, the high-temperature resistant solenoid valve opens, and the water pump works. It is injected into the furnace through the one-way valve. When the solenoid valve or one-way valve is blocked or damaged, and the water supply reaches a certain pressure, it will overflow through the overpressure valve and return to the water tank, thereby protecting the water pump. When the water tank runs out of water or there is residual air in the water pump pipeline, only air is allowed to enter without water. As long as the exhaust valve is used to quickly exhaust, and when water is sprayed out, the exhaust valve is closed, and the water pump can work normally. The main component in the water supply system is the water pump, which mostly uses multi-stage vortex pumps with high pressure and large flow rate, and a small portion uses diaphragm pumps or vane pumps.
2. The liquid level controller is the central nervous system of the generator's automatic control system, divided into two categories: electronic and mechanical. The electronic liquid level controller controls the liquid level (i.e. the difference in water level) through three electrodes with varying heights, thereby controlling the water supply of the water pump and the heating time of the furnace electric heating system. The working pressure is stable and the application range is relatively wide. The mechanical liquid level controller adopts a stainless steel floating ball type, suitable for generators with large furnace liner volumes. The working pressure is not very stable, but it is easy to disassemble, clean, maintain, and repair.
3. The main body of the furnace is generally made of seamless steel pipes specially designed for boilers, which are slender and upright. The electric heating system uses electric heating tubes mostly composed of one or more stainless steel electric heating tubes bent and combined, and their surface load is generally around 20 watts per square centimeter. Due to the high pressure and temperature during normal operation of the generator, the safety protection system can ensure its safety, reliability, and efficiency during long-term operation. Generally, safety valves, one-way valves, and exhaust valves made of high-strength copper alloys are used for three-level protection. Some products have also added water level glass tube protection devices, increasing the user's sense of safety.
