What is lift?

Generally refers to the height to which the pump lifts the material. It has little to do with the transportation distance. It is just a matter of pressure drop. The unit is generally meters and can also be understood as a part of the lift of the pump capacity including the suction height.

Head is the effective energy obtained by unit weight of liquid flowing through the pump. It is an important working energy parameter of the pump, also known as pressure head. It can be expressed as the increase of pressure energy head, kinetic energy head and potential energy head of the fluid, that is, H=(p2-p1)/ρg+(c2-c1)/2g+z2-z1 where H——Head, m ； 　　p1, p2——the pressure of the liquid at the pump inlet and outlet, Pa ； 　　c1, c2——Flow velocity of fluid at the pump inlet and outlet, m/s ； 　　z1, z2——Height of entrance and exit, m ； 　　ρ——liquid density, kg/m3 ； 　　g——gravitational acceleration, m/s2. 　　The head, flow and power of the water pump are important parameters for examining the performance of the water pump.: 　 　Lift The head of a water pump refers to the height at which the pump can lift water. It is usually represented by H and the unit is m. The lift of the centrifugal pump is based on the center line of the impeller and consists of two parts. The vertical height from the center line of the water pump impeller to the water surface of the water source, that is, the height at which the water pump can suck water up, is called the suction head, or suction lift for short. ； The vertical height from the center line of the water pump impeller to the water surface of the outlet pool, that is, the height at which the water pump can press the water up, is called the pressure head, or pressure stroke for short. That is, the water pump head = water suction head + pressurized water head. It should be noted that the head marked on the nameplate refers to the head that the water pump itself can produce. It does not include the loss of head caused by frictional resistance of the pipeline water flow. When choosing a water pump, pay attention not to ignore it. Otherwise, water will not be pumped out. 　　 　　 　　

Using water as the standard medium, it refers to the height that the pump can lift water

　　The head of a centrifugal pump is also called the pressure head of the pump, which refers to the energy obtained by a single weight fluid through the pump. 　　The lift of the pump depends on the structure of the pump (such as the diameter of the impeller, the bending of the blades, etc.) and the speed.

Lift is generally for a pump and represents a performance of the pump, its ability to provide pressure.

definition: The energy gained by unit weight of liquid passing through the pump is called head. The lift of the pump, including the suction lift, is approximately the pressure difference between the pump outlet and inlet. The head is represented by H and the unit is meters (m).

The lift of the pump has nothing to do with the medium of the pump, but is only related to the parameters of the pump itself. For example, the diameter of the impeller, the bending condition of the blades, etc., and the rotation speed.

Simply put, the head is the height the pump can reach.

What is lift? What letters are used? What unit of measurement is used? and pressure conversion and formula? 　　answer: The energy gained by unit weight of liquid passing through the pump is called head. The lift of the pump, including the suction lift, is approximately the pressure difference between the pump outlet and inlet. 　　The head is represented by H and the unit is meters (m). 　　The pressure of the pump is expressed by P, the unit is Mpa (MPa), H=P/ρ. If P is 1kg/cm2, then H=(lkg/cm2)/(1000kg/m3) H=(1kg/cm2)/(1000kg/m3)=(10000kg/m2)/1000kg/m3=10m1Mpa=10kg/c m2,H=(P2-P1)/ρ (P2=outlet pressure P1=inlet pressure)

To put it simply, at the production site, it depends on the pressure at the pump outlet.
