Non-pressure flat plate solar water heater working principle:

Non-pressure solar water heater is such a kind of thermosiphon solar water heating device, which flat plate collector placed below high pressure hot water tank. The tank and flat plate are connected with two circulation pipes to form a open-loop solar water heating system, tank is non-pressure design, based on gravity. The whole system only use water, can’t use other liquid as circulation medium. By continuously circulating in this way, the water is heated directly inside flat collector and rise to be stored inside hot water tank.

Water cutting, also known as water knife, English name is high pressure water cutting, that is, high-pressure water jet cutting technology. It is a machine that uses high-pressure water flow to cut. Under the control of the computer, the workpiece can be carved arbitrarily, and it is less affected by the material texture. Because of its low cost, easy operation and high yield, water cutting is gradually becoming the mainstream cutting method in industrial cutting technology.
