Why Is Isothermal Efficiency Important In A Liquid Ring Pump?
Posted in Uncategorised, on October 19, 2022 By Admin
Liquid ring pumps are an integral part of several industries such as the petrochemical and pharmaceutical. It is useful in environments with sensitive requirements as the impeller, casing and other parts of the pump are not in contact with one another, a necessity for processing volatile liquids and fluids. Apart from smooth functioning, a peculiar feature about liquid ring pumps is that they also function as a compressor. In this context, one vital factor that decides compressor selection is known as isothermal efficiency. Its meaning and importance in liquid ring pumps will be examined below.
Role of isothermal efficiency in pump selection.
Before understanding isothermal efficiency it is vital to understand isothermal compression.
What is isothermal compression?
In most cases, when the pressure of a liquid or fluid is increased or its volume is decreased, the temperature can also rise as a byproduct. However, in case of isothermal compression, the pressure can be maximized without affecting the core operating temperature. With this definition, it’s time to explore the meaning of isothermal efficiency.
What is isothermal efficiency?
In a liquid ring pump, the vanes of the impeller have a certain curvature in order to maximize energy transfer. Moreover, since the compression of the liquid depends on the rotary movement of the impeller, isothermal efficiency can be defined as the ratio between the energy required for isothermal compressions versus actual energy used to power the compressor.
Thus, with an appropriate impeller design and proper maintenance of seals, the loss of pressure in a liquid ring pump is minimized, thereby boosting its isothermal efficiency. Therefore, with a liquid ring pump featuring optimized isothermal efficiency, energy consumption levels can be significantly reduced.
