Core indicators of electric pumping stations

1. Performance parameters

Flow rate (Q): the volume of liquid delivered per unit time (m³/h or L/min), which determines the processing capacity of the pump station.

Head (H): the vertical height (meters) to which the liquid is lifted, reflecting the pressure output capacity of the pump.

Power:

Input power: the electrical energy consumed by the motor (kW).

Output power: the energy actually obtained by the liquid, the ratio of the two determines the efficiency.

Efficiency: pump efficiency (hydraulic efficiency), motor efficiency and system overall efficiency, high energy efficiency reduces operating costs.

Speed: pump shaft speed (RPM), which affects flow, head and wear.

Pressure parameters:

Outlet pressure: the maximum working pressure must meet the system design requirements.

Potential suction head (NPSH): the minimum suction pressure to avoid cavitation, which affects the installation height of the pump.

2. Energy efficiency indicators

Energy efficiency level: such as IE3/IE4 motor standards, in line with international energy efficiency specifications.

Unit energy consumption: the power consumption per unit volume of liquid delivered (kWh/m³), which measures economic efficiency.

Power factor: motor power utilization rate, reducing reactive power loss.

3. Reliability index

MTBF (mean time between failures): reflects the stability of the equipment, the higher the value, the more reliable it is.

Maintenance cycle: lubrication, component replacement frequency, affecting operation and maintenance costs.

Design life: expected service life of key components (such as bearings, seals) (hours/year).

4. Control and automation

Frequency conversion speed regulation: adapt to flow/pressure changes, save energy and extend life.

Intelligent monitoring: real-time monitoring of sensors (temperature, vibration, pressure, etc.), supporting remote management.

Protection function: overload, overheating, phase loss, dry running protection to prevent equipment damage.

5. Environmental adaptability

Operating temperature range: ambient temperature and medium temperature limit for normal operation of the equipment.

Protection level (IP): dust and water resistance (such as IP67), suitable for humid/dusty environments.

Corrosion resistance: the ability of materials (such as stainless steel, engineering plastics) to cope with corrosive media.

Explosion-proof level: Ex certification, suitable for flammable and explosive environments.

6. Safety indicators

Insulation level: temperature resistance level of motor insulation material (such as F grade 155℃).

Leakage protection: mechanical seal/double seal design to prevent medium leakage.

Noise level: operating noise (dB), affecting the comfort of the working environment.

Vibration level: vibration amplitude (mm/s), exceeding the standard may indicate a fault.

7. Application-related indicators

Media type: compatibility with clean water, sewage, corrosive liquids or particulate matter.

Installation method: vertical/horizontal, submersible/dry installation, suitable for different scenarios.

Interface size: inlet and outlet flange/pipe diameter (such as DN50), matching system requirements.

Supplementary indicators

Certification standards: comply with ISO, GB, ANSI and other industry certifications to ensure quality.

System response time: the adjustment speed of automated control, affecting process stability.

Maintenance convenience: modular design for quick repair.
