The performance adjustment of a د ویشلو قضیه ډبل سکشن پمپ  involves a systematic evaluation and modification of key operational parameters to meet specific application requirements. This process ensures that the pump operates efficiently under varying system conditions. The following sections outline the critical steps and considerations in performance adjustment calculation.

1. Hydraulic Power and Efficiency Calculation

Hydraulic power (N) is determined by the torque (M) and angular velocity of rotation (). The formula used is:

To assess hydraulic efficiency, it is essential to factor in the pump's flow rate (Q). Hydraulic efficiency is typically evaluated through performance curves, such as the head vs. flow rate (H-Q) and efficiency vs. flow rate (-Q) curves. These curves help determine the optimal operational range for the pump under different flow conditions.

2. Flow Rate and Head Adjustment

Flow rate and head are the primary parameters adjusted to meet system requirements. The flow rate is usually selected based on the production process's minimum, normal, and maximum flow demands.

For large flow and low head pumps: a flow margin of approximately 5% is recommended.

For small flow and high head pumps: a 10% flow margin is more appropriate.

The pump head should also include a safety margin of 5% to 10% above the system's actual head requirement to ensure stable operation.

3. Additional Adjustment Considerations

Beyond flow and head, other factors can influence the performance of a د ویشلو قضیه ډبل سکشن پمپ:

Impeller Trimming:Reducing the impeller diameter to adjust flow and head.

د سرعت سمون:Modifying pump speed to shift performance curves.

Internal Component Wear:Wear and clearances between components can reduce efficiency and need routine evaluation and correction.

These adjustments must be based on thorough inspection and analysis to maintain or improve hydraulic and mechanical performance.

4. Actual Adjustment Procedures

In practical scenarios, performance adjustment may involve:

Disassembling the pump for inspection

Identifying worn or damaged parts

Repairing or replacing components

Reassembling with precise alignment

It is critical during reassembly to check concentricity and axial positioning of the rotor and stationary parts. Proper installation ensures optimal performance and prevents premature wear.
