If you want to know everything about ປັ໊ມ turbine ຕັ້ງຫຼາຍຂັ້ນຕອນ , it is also important to know about the fluids and liquids it transports.

Fluids and Liquids

There is an important distinction between fluids and liquids. Liquids refer to any substance that is between the solid and gas phases. Whether a substance is in the liquid state depends on the temperature and pressure it experiences, as well as the intrinsic properties of the substance itself.

A fluid is any substance that can flow continuously and is able to form any shape of container that contains it. While this perfectly describes liquids, it can also be used to describe gases. In other words, all liquids are fluids, but not all fluids are in the liquid state. Therefore, generally speaking, when the word "fluid" is used in the ປັ໊ມ turbine ຕັ້ງຫຼາຍຂັ້ນຕອນ, it refers to liquids, as pumps are not designed to transport gases.

Liquids have the main physical properties that need to be considered in pumping applications, namely viscosity, density, and vapor pressure (vaporization pressure). These properties are crucial to understanding how a liquid behaves and which pump is best suited for it.

Viscosity refers to the resistance of a liquid to flow, or how "sticky" a liquid is. This will affect the flow rate, total head, efficiency, and power of a multistage vertical turbine pump.

Density refers to the mass of a substance contained in a certain volume. In pumping, it is also often referred to as relative density (specific gravity), which is the ratio of the density of a substance to the density of water at a specific temperature. Density and specific gravity are needed to determine the power required to move one fluid relative to another.

Vapor pressure is the pressure at which a liquid begins to evaporate (vaporize), and it is critical to monitor this in a pump system. If the pressure in the pump is lower than the vaporization pressure of the liquid, cavitation can occur.

Understanding the difference between fluids and liquids and how liquids behave is critical to the function of a multistage vertical turbine pump .
