How does a diesel engine self priming pump work?
Date: 2019-03-13
The principle of the diesel engine self priming pump is to use the flow velocity of the water. The impeller drives the pump impeller to pump water onto the river bank. The pump can be pumped by throwing it into the river, but water flow must be in a hurry or where there is a drop.
The diesel self priming pump is different from the general centrifugal pump. Before the centrifugal pump is in operation, the pump body and the inlet pipe must be filled with water to be in a vacuum state. When the impeller rotates rapidly, the blade causes the water to rotate quickly, and the rotating water flies from the impeller under the action of centrifugal force. After the water is thrown, the central portion of the impeller forms a vacuum region. The water of the water source is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). This cycle is not enough, you can achieve continuous pumping. The diesel self-priming pump does not need to pump water, which is the origin of the diesel self priming pump.
