High-efficiency energy-saving multi-stage pumps are key equipment widely used in modern industry. To ensure their normal operation and extend their service life, correct debugging and calibration methods are particularly important.

I. Debugging Methods

1. Preliminary Preparation: Ensure stable power supply, check if the pump is firmly installed, if the inlet and outlet valves are open, and if the liquid pipeline is unobstructed.

2. Motor Operation: Start the motor, observe whether the direction of rotation is consistent with the direction indicated by the pump arrow, and pay attention to whether the motor runs smoothly and whether there are any abnormal sounds.

3. Liquid Filling: Gradually open the inlet valve to allow liquid to enter the pump, and observe whether the pump pressure and flow rate are normal.

4. Step-by-Step Pressure Increase: According to the needs, gradually increase the outlet valve pressure, and observe whether the pump's outlet flow rate, power, and efficiency meet the design requirements.

5. Performance Test: During the debugging process, record the performance data of each stage, such as flow rate, pressure, and power, draw performance curves, compare them with theoretical data, and ensure that the pump's performance meets the design requirements.

II. Calibration Methods

1. Geometric Dimension Calibration: Check the main components of the pump, such as the impeller and pump casing, to ensure that their dimensional accuracy and shape tolerances are within the allowable range.

2. Axis Calibration: Use a dial indicator to check whether the pump axis is perpendicular or parallel to the ground, ensuring that the pump will not generate additional wear during operation due to axis deviation.

3. Pressure Gauge Calibration: Install a pressure gauge and check whether its pressure readings are accurate at different flow rates.

4. Flow Rate Calibration: Use a flow meter to measure the pump's flow rate, ensuring that its actual operating flow rate is consistent with the calibrated flow rate.

5. Efficiency Calibration: During pump operation, calculate the pump's efficiency by measuring the input power and output power, and compare it with the theoretical data. If there are discrepancies, adjustments need to be made.

Precautions:

1. During debugging and calibration, strictly follow the safety operating procedures to ensure the safety of personnel and equipment.

2. During debugging, pay attention to observing the pump's temperature, vibration, and sound. If any abnormality is found, stop the machine immediately for inspection.

3. During calibration, use professional tools and equipment to ensure the accuracy of the measurement data.

In summary, the debugging and calibration of high-efficiency energy-saving multi-stage pumps are crucial for ensuring the pump's performance and service life. In actual operation, it is necessary to combine theoretical data and actual on-site conditions for detailed and comprehensive inspection and adjustment.
