The performance adjustment calculation of двострука усисна пумпа са подељеним кућиштем involves many aspects. The following are the key steps and considerations:

1. Calculation of Hydraulic Power and Efficiency

Hydraulic power can be calculated by torque and angular velocity of rotation, and the formula is: N=Mω. Among them, N is hydraulic power, M is torque, and ω is angular velocity of rotation.

The calculation of hydraulic efficiency needs to consider the flow rate Q of the pump, and its calculation formula involves parameters such as flow rate, torque and angular velocity of rotation. Usually, the curve of head and efficiency changing with flow rate (such as H-Q curve and η-Q curve) can be used to evaluate the performance of the pump under different working conditions.

2. Adjustment of Flow Rate and Head

When adjusting the performance of двострука усисна пумпа са подељеним кућиштем , flow rate and head are two important parameters. The flow rate of the pump is selected according to the minimum, normal and maximum flow rates in the production process. It is usually considered according to the maximum flow rate and a certain margin is left. For large flow and low head pumps, the flow margin can be 5%; for small flow and high head pumps, the flow margin can be 10%. The selection of head should also be based on the head required by the system. A margin of 5%-10% should be enlarged.

3. Other Adjustment Factors

In addition to flow and head, the performance adjustment of the подељен случај double suction pump may also involve other factors, such as the cutting of the impeller, the adjustment of the speed, and the wear and clearance adjustment of the internal components of the pump. These factors may affect the hydraulic and mechanical performance of the pump, so they need to be considered when making performance adjustments.

4. Actual Adjustment Operation

In actual operation, performance adjustment may involve steps such as disassembly, inspection, repair and reassembly of the pump. When reassembling, it is necessary to ensure the correct installation and positioning of all parts, as well as adjust the concentricity and axial position of the rotor and the stationary part to ensure the best performance of the pump.

In summary, the calculation of the performance adjustment of the split case double suction pump is a complex process that requires consideration of multiple factors and steps. When making performance adjustments, it is recommended to refer to the technical manuals and guidelines provided by the pump manufacturer and consult professional technicians or engineers to ensure the accuracy and effectiveness of the adjustment.
