"Pump Shaft Torque" refers to the amount of rotational force that is required to turn the pump shaft. It is an important factor to consider in the design and operation of a pump, as it affects the efficiency and performance of the pump.
Calculating Pump Shaft Torque is important because it helps determine the amount of power needed to drive the pump, as well as the size and type of motor that should be used. It also helps in selecting the appropriate pump for a specific application.
There are several factors that can affect Pump Shaft Torque, including the type and size of the pump, the type of fluid being pumped, the pump speed, and the pump efficiency. Other factors may include the presence of any friction or resistance in the pump system, as well as any changes in the fluid viscosity or temperature.
Pump Shaft Torque can be calculated using the formula: T = (P x Q) / (63025 x n), where T is the torque (in lb-ft), P is the pressure (in psi), Q is the flow rate (in gpm), and n is the pump speed (in rpm). It is important to note that this formula is only an estimate and may vary depending on the specific pump and application.
Pump Shaft Torque is typically measured in pound-feet (lb-ft) or Newton-meters (N-m). In some cases, it may also be measured in inch-pounds (in-lb) or kilogram-meters (kg-m). The units used may vary depending on the application and industry standards.
