large number of wholesale engraving machine spindle special cooling water pumps can be divided into lifts according to different lifts. Meter, meter, meter, meter, meter. The power supply voltage is single-phase and can be completely immersed in water. The rapid rotation of the internal turbine absorbs water. Provide cooling to the electric spindle under high pressure! Special water pump for engraving machine. The submersible pump with a lift of 1 meter is mainly used for motors with a kilowatt spindle motor or above. The advantage of using this model is that it has a large flow of water, a large water volume and a high lift. Let’s give a detailed introduction to the lift (head) of the submersible pump for engraving machine. The unit weight of the water pump
Liquid The work done is the added value of energy per unit weight of liquid after it passes through the water pump. Commonly used letters indicate the height of the liquid column.
Other units, (atmospheric pressure of each project)
=. .
The lift is calculated as =
The pump lift =+ is the water lift height, that is, the elevation difference from the water surface at the inlet to the water surface at the outlet. It is the calculation of head loss including head loss along the way and local head loss. Darcy's formula or Xie Cai's formula
=*^/ is called the local head loss coefficient. Please check the relevant literature. Generally speaking, the flow rate in the pipe occurs at the entrance. Bend the valve outlet and other places.
The water pump head is an important working energy parameter of the water pump. For people in the industry, the water pump head calculation formula is a very commonly used technical information. The following World Factory Pump Valve Network will introduce the water pump head calculation formula in detail.
Lift usually refers to the maximum height that a water pump can lift water. The most commonly used formula for calculating pump head is =(-)/+(-)/+-.
Among them, the pressure of the liquid at the inlet and outlet of the lift pump, the flow rate of the fluid at the inlet and outlet of the pump/the height of the inlet and outlet, the density of the liquid/acceleration of gravity/.
Usually choose a centrifugal clean water pump with a specific speed of ~. The flow rate of the water pump should be . The loss along the way per meter of pipe length is the calculation formula of the water pump head:
=△+△+. (+)
△ is the water pressure drop of the evaporator of the chiller.
△ is the loop The water pressure drop of the unit in parallel that accounts for the largest water pressure loss of the end device of the air conditioner.
is the pipe length of the most unfavorable loop
is the sum of the local resistance equivalent lengths in the most unfavorable loop When the most unfavorable loop is longer, the value is .~. When the most unfavorable loop is shorter, the value is .~..
