Before starting the centrifugal pump, it is necessary to fill the casting and suction pipe with water, and then start the motor.

In pump impeller center, as the water in the centrifugal force was thrown out and form a vacuum, the water in the suction pool is pressed into the casting in atmospheric pressure. The action of the impeller increases the fluid's velocity and pressure and also directs it towards the pump outlet to trasnsport water.\u003cbr data-mce-fragment=\"1\"\u003e.Note: The product is intended for DIY players.

You will be completely fascinated by the light and the magic process of energy conversion if the engine is working in a dark environment. \u003cbr\u003e.Excellent Workmanship: The engine is made of zinc alloy, with plating surface for rich metallic luster and enhanced industrial texture. Features high-precision components for smooth and long-time running. \u003cbr\u003e.Multiple Uses: The principle of the closed cycle reciprocating engine is that the gas is compressed and expanded periodically at different temperatures by external heating. And the engine is easy to operate. Great for physical\/mechanical demonstration, classroom teaching, scientific experiments, display, desktop decor, etc. \u003cbr\u003e.Perfect Gift: This is an interesting and imaginative artwork for visual and aesthetic enjoyment, making it suitable for children, teachers, students and technology enthusiasts. The engine is a perfect gift for family and friends on Christmas and birthdays.
