Pump working principle

A pump is a machine used to transport liquids or pressurize fluids. It is widely used in shipbuilding, oil extraction industry, cranes and other aspects. Different uses of the pump although the structure, materials are different, but the pump works are the same, let's learn more about the working principle of the pump. Pump works: Open the pump, the impeller in the pump body to do high-speed rotation (before the pump to open the pump to make the body full of liquid), the pump body with a rotating impeller, the centrifugal force in the liquid produced by the impeller Throw out the thrown liquid in the pump chamber diffusion speed becomes slower, the liquid is thrown out, the center of the impeller to form a vacuum low pressure zone, liquid in the pool under the action of atmospheric pressure, the suction pipe into the pump. Pump body diffusion chamber volume is certain, with being thrown out of the liquid increases, the pressure is also gradually increased, and finally discharged from the pump outlet. As a result, the liquid is sucked up continuously from the sump and discharged continuously from the pump outlet. Pumps in the long-term use, there will be erosion of the pump, erosion and erosion problems, so when we buy, we should choose the right pump, the pump can not choose the amount of water is too large, not only does not increase the cost benefits; choice of suitable local conditions Of the pumps, mountain wells and other irrigation areas need to choose a larger lift, the plain area on the amount of water required to lift lower.

Stainless steel thread inserts are mainly 304 stainless steel, 321 stainless steel, 316 stainless steel. 304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3, also known as 18/8 stainless steel. With high temperature resistance of 800 °C, it has the characteristics of good processing performance and high toughness. 321 stainless steel is Ni-Cr-Ti type austenitic stainless steel, which has abrasion resistance, high temperature resistance, creep resistance, etc., and is used for manufacturing lining and conveying pipeline of wear-resistant acid container and wear-resistant equipment. 316 stainless steel is an austenitic stainless steel. Due to the addition of Mo element, it has a great improvement in corrosion resistance and high temperature strength. It can withstand high temperatures up to 1200-1300 degrees and can be used under harsh conditions.
