‌ 

Applications: 

Screw pumps have a wide range of applications across various fluid transport sectors:

Petrochemical Industry: Transport of petroleum products and chemical raw materials.

Environmental Water Treatment: Handling urban sewage, industrial wastewater, and water treatment processes.

Food and Pharmaceutical Industries: Transport of food ingredients and pharmaceutical products (e.g., milk, juice, medicinal liquids).

Marine Transport: Circulation of marine fuel, lubricants, and bilge water.

Construction: Transport of construction materials such as concrete and mortar.

‌ 

Parameter Introduction: 

Key parameters of screw pumps include:

Flow Rate (Q): Measured in m³/h or L/min, indicating the volume of liquid pumped per unit time.

Head (H): Measured in meters, representing the vertical lifting height of the liquid.

Speed (n): Measured in r/min, reflecting the rotation speed of the screw pump.

Power (P): Measured in kW, indicating the power required to pump the liquid.

Temperature (T): Measured in °C, specifying the suitable temperature range for the pumped liquid.

‌ 

Selection and Usage Notes:

Precise Selection: Choose based on actual needs, considering flow rate, head, speed, and power.

Material Compatibility: Consider the characteristics of the pumped liquid and select appropriate pump casing and screw materials.

Regular Maintenance: Implement periodic inspections and maintenance to ensure stable operation and extend the pump's lifespan.
