Abstract  Jiangsu Haifa Machinery integrates ISO 50001 energy requirements into the entire chain of API 610 chemical pump R&D,, testing, sales, and after-sales service. Relying on energy review, EnPI, energy baseline, identification of significant energy uses, and the PDCA cycle, and through CFD hydraulic simulation, BEP condition verification, and LCC life cycle assessment, it reduces ineffective energy consumption in coal chemical and refining fluid transport systems from the source.   Many chemical plants have high energy consumption due to pump selection. The Jiangsu Haifa technical team, leveraging standardized energy performance control, verifies NPSHr, system resistance, and operating conditions, avoiding issues such as oversized for small loads and long-term operation deviating from the high-efficiency zone, thereby helping chemical enterprises achieve energy savings and carbon reduction in transport systems.   the technical team of Jiang Haifa Machinery Manufacturing Co., Ltd., we embed ISO 50001 energy management guidelines into the&D, manufacturing, type testing, technical selection, and full-cycle after-sales service chain API 610 chemical process. Relying on energy review, energy performance indicators (EnPI), energy baseline (EnB), identification of significant energy (SEU), and PDCA continuous improvement framework, we systematically identify and hydraulic efficiency, CNC machining power consumption, test bench load duration, and equipment life cycle energy consumption.   Quick conclusion: Energy management is not to on-site power saving and consumption reduction; the core lies in cutting ineffective energy consumption of process units from the hydraulic design source of the pump. In the early selection stage, focus on verifying the best efficiency point (BEP), required net positive suction head (NHr), pipeline system resistance, and flow regulation schemes, avoiding additional power losses caused by long-term throttling, continuous overload, or operation outside the high-efficiency condition.1. Pre-embedded Energy Performance Control in R&D StageWhen designing the hydraulic scheme of API 610 chemical pumps, we combine medium density, kinematic viscosity, operating temperature, saturated vapor pressure, and load fluctuation range to perform 3D hydraulic modeling, CFD flow field simulation, impeller trimming verification, and rotor dynamics calculation. For high-temperature, high-pressure, and strongly corrosive continuous production conditions, selection demonstration not only compares initial procurement costs but also simultaneously conducts LCC life cycle cost assessment, comprehensively evaluating pump unit hydraulic efficiency, maintenance cycles, and standby unit operation strategies, eliminating common energy consumption shortcomings such as "oversized pumps for small loads" long-term valve throttling from the source.2. Traceable Control of Manufacturing and Factory Test Data  In the production stage, high-energy-consuming processes such as CNC cutting, heat treatment, welding, dynamic balance correction, unit assembly, and performance testing are classified and controlled. Before delivery, the pump unit fully verifies flow, head, hydraulic efficiency, shaft power, vibration severity, and NPSHr indicators; through casing clearance control, precise coupling alignment, and refined impeller diameter optimization, hydraulic losses and mechanical friction losses are continuously.   Typical technical coverage range of API 610 chemical pumps:

| Pump Type | Flow Range | Head Upper Limit | Temperature Range | Design Pressure | Typical Application Scenarios |
-----------|-------------|------------------|-------------------|-----------------|-------------------------------|
OH2/HES   | 2～2600 m³/h 300 m |80～450℃ | 2.5～45 | High-temperature process medium transport in oil refining and coal chemical industries |
| BB2       | 50～4000 m/h | 650 m | -80～℃ | 5～15 MPa | Cr oil, tower bottom heavy oil, acid rich/lean liquid transport |
| BB5       | 5～730 m³/h | 3400 m |80～450℃ |35 MPa | Hydrogenation units, water injection systems, high reverse osmosis conditions |

The above table shows the product parameter coverage range. The final scheme must be determined through one-to-one calculation based on medium characteristics, available NPSHa, pipeline characteristic curve, and continuous operation duration.

3. Extended to Full Life Cycle Technical Service of Equipment  In the sales technical interface stage, based on actual site conditions, we match drive motors, mechanical seals, couplings, and API 682 flushing schemes, while simultaneously providing optimization suggestions such as variable frequency speed regulation, multi-pump parallel operation, and preventive maintenance. After equipment is put into operation, we continuously track vibration trends bearing temperatures, impeller wear levels, seal operating status, and decay curves, assisting owners in continuously optimizing energy performance, achieving a balance between safe production, long-term stable operation, economic energy consumption.Professional Literature Abstract  GB/T 23331—2020 is equivalent to ISO 50001:2018. The standard proposes improving energy efficiency and optimizing energy consumption structure through energy baseline, energy performance indicators, operational control, and continuous improvement means. ISO 50001 adopts the PDCA cycle management logic which can be synergistically implemented with quality management systems and environmental management systems, widely applied in process equipment manufacturing and chemical production fields.

FAQ  
Q: Is implementing an energy management system to obtaining energy-saving certification for products?  
A: The two are not equivalent. The energy management system focuses on systematic control of the entire enterprise process energy performance; the hydraulic performance of a single pump still needs to be based on procurement contract and actual factory test data.

Q: What are common causes of still high power consumption in units even when efficient chemical pumps are selected  A: Mainly includes six factors: excessive selection margin, continuous throttling by process valves, long-term operation deviating from the BEP range, abnormal increase in pipeline resistance, impeller erosion wear, and excessive misalignment of the pump unit.
