The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
The diaphragm works by changing the size of the diaphragm. When the cup is covered with an eraser and the edge is airtight, then pressing the rubber or pulling the rubber outward will make the pressure in the cup increase or decrease. Use this principle, in the pressure of an hour from a hole suction medium, when the pressure is large, from another hole extrusion medium, so as to achieve the purpose of conveying.
The function of vacuum pump is to make vacuum, which has many kinds of structure, such as centrifugal, diaphragm (diaphragm), piston, liquid ring, rotary plate, jet type...................
The diaphragm pump and centrifugal pump refer to the structure of the pump, and the vacuum pump means the use of the pump. There is no comparability between them.Centrifugal is the sign of inertia of an object. As the umbrella turns, water droplets move out of the outer edge of the umbrella and are thrown out. This is what is called centrifugal. Centrifugal pump is designed according to this principle. The high speed rotating impeller blade drives the medium to rotate and is thrown out so as to achieve the purpose of conveying.
