Large high-quality stainless steel box-type tank body and manufacturing method thereof

The invention discloses a large high-quality stainless steel box-type tank body and a manufacturing method thereof. All structural parts are manufactured by bending and welding uniform same-roll plates, so that a welding process is uniform, the performance is excellent, the tank body has important significance in occasions with high material requirements, such as high-quality water supply and corrosive water use occasions, and the tank body is easy to machine; and on the premise that materials are saved and the machining process is simplified, the chemical and physical properties of a finished product combined water tank are exceeded. Meanwhile, a full-water, middle and water-shortage double-liquid-level control automatic operation mode is adopted, so that the situation that evacuation, overflow and liquid level fluctuation false alarm of the box-type tank body are avoided is guaranteed; and common discrete magnetic liquid level sensors are adopted as liquid level sensors, so that a PLC does not need to be ad
