Advantages of pipeline pumps

1.  High efficiency : Designed to adapt to continuous operation of pipelines with minimal energy loss.

2.  High reliability : Compact structure, few parts, suitable for harsh working conditions.

3.  Versatility :Applicable to clean water, petroleum, chemical fluids, etc., covering a wide range of industries.

4.  High reliability : Impellers, shafts and other components are adapted to high pressure conditions and can operate stably for a long time.

5.  Economical and efficient : Strong durability (service life ≥ 8 years) and low maintenance cost.

6.  Automation-friendly : Easy to integrate with control systems, such as variable frequency drives,  and supports remote monitoring and automatic adjustment.

Main Components of a Pipeline Pump

1.  Impeller:The core energy transmission component, which transmits kinetic energy to the fluid by rotation. The material can be cast iron, stainless steel, and high chromium cast iron for particles.

2.  Diffuser:A stationary component that converts velocity into pressure.

3. Pump casing : Encloses the impeller, guides fluid flow, and protects internal components

4.  Shaft : Connects the impeller and the motor to transmit power.

5.  Sealing : Prevent leakage along the shaft and ensure the sealing of the pump body.

6.  Bearing : Supports the rotation of the pump shaft and reduces friction and wear. Rolling bearings are lubricated with grease, while sliding bearings are lubricated with thin oil.

7.  Motor:Electric motor or diesel engine.

Application scenarios

1.  Oil and gas industry : Long-distance transportation of crude oil, refined products or natural gas.

2.  Water supply system : Transporting clean water from reservoirs to urban pipe networks and rural irrigation systems.

3.  Chemical processing : Safe transportation of corrosive and hazardous chemicals.

4.  Mining operations : Transporting slurry and mineral solutions from mining sites.

5.  Power plant : Transportation of circulating cooling water, boiler feed water and other fluids.

Installation Tips

1.  Series/parallel installation : Based on flow/lift requirements, multiple pipeline pumps can be connected in series to increase lift or in parallel to increase flow.

2.  Pipeline alignment : Ensure the pump inlet/outlet is coaxial with the pipeline to avoid pipeline stress being transferred to the pump body.

3.  Fixing and shock absorption :Install on a solid foundation and add shock-absorbing pads to reduce vibration. outdoor installation requires protection from rain and sun.

4.  Exhaust treatment : Exhaust the air in the pump before starting to prevent cavitation.

Maintenance Tips

1.  Routine inspection (once a month) :Check whether the seal is leaking under 5 drops/minute, whether the motor is overheating, and whether there is any abnormal noise during operation.

2.  Lubrication maintenance : Add lubricating oil to the bearings every three months to avoid dry friction.

3.  Cleaning and maintenance : Regularly clean the pump inlet filter and scale inside the pump casing to prevent blockage.

4.  Comprehensive maintenance (once every 6-12 months) :Disassemble and check the wear of impeller and seals, replace aging parts; calibrate the coaxiality of motor and pump shaft.

Common Troubles and Remedies

Selection Points

1.  Parameter matching :Determine the flow rate and head according to the working conditions to ensure that the rated values cover the requirements.

2.  Fluid adaptation : Select materials and impellers based on fluid corrosivity, temperature, and viscosity.

3.  Space adaptation : Vertical type is suitable for narrow space, horizontal type is suitable for high flow rate.

4.  Energy saving first :Energy-saving pumps with variable frequency are preferred to reduce operation and maintenance costs.

5.  Material compatibility : The pump body and impeller must be resistant to fluid wear and corrosion (such as corrosion-resistant alloys for seawater).

6.  Power source :Electricity, diesel or other.

Innovati ve Direction  in Pipeline Pump Technology

1.  Smart pumps : Equipped with sensors and IoT technology, they enable real-time monitoring.

2.  Environmentally friendly design : Using materials and designs that reduce environmental impact.

3.  Automation and control systems :Improve efficiency and reduce manual oversight.

4.  Energy Recovery Systems : Capture and reuse energy within the system.
