If the pump frequency energy efficiency of certain air compressor energy-saving projects, when asked to adjust the flow rate drops, the speed N can be decreased in proportion, but this time the shaft output power P was established party relationships decreased. That is the pump motor power consumption and speed approximation cubic Ratio. For example: a pump motor power 55KW, air compressor energy conservation principle, when the speed dropped to 4/5 of the original speed, the power consumption is 28.16KW, Shangqiu air compressor energy saving, saving 48.8%, when the speed dropped to 1/2 the original speed, the power consumption is 6.875KW, saving 87.5 percent. pump impeller interior consists of two blades, the front and rear cover to form a complete flow field, the viewer can see synchronous rotation with the impeller is time-independent steady relative flow, we require the calculation of flow field in any size and direction of the relative velocity of the point, in order to establish our mathematical model of the impeller.
