In process industries such as petrochemicals and oil refining, the selection of API610 oil pumps directly affects the safety, stability, and economy of production systems. As specialized conveying equipment compliant with the API 610 standard, its selection must follow a systematic procedure, covering core links including confirmation of operating condition parameters, verification of standard compliance, and comparison of technical schemes.
The primary step in selecting an API610 oil pump is to comprehensively collate operating conditions and conveying requirements, and clarify core parameters to lay the foundation for pump selection. The following contents need to be focused on confirming:
In terms of medium properties, it is necessary to clarify the name, density, viscosity, corrosivity, and solid content of the conveying medium. Density should include the standard density at 20°C and the density under operating temperature; for viscosity, the measurement temperature of kinematic viscosity or dynamic viscosity must be specified; for corrosivity, indicators such as sulfur content and pH value should be examined; and for solid content, the particle size and concentration must be clearly defined. For instance, when conveying sulfur-containing crude oil, special attention should be paid to the sulfur resistance of materials to prevent component corrosion failure in the later stage.
Process parameters must be collected accurately, including design flow rate, design head, operating temperature, and system pressure. The design flow rate should cover values under normal, maximum, and minimum operating conditions; the design head must meet the total requirements of system resistance loss and conveying height, with a 5%–10% margin reserved; the operating temperature should specify the inlet and outlet temperature ranges of the medium; and the system pressure should record the inlet pressure and outlet pressure. In addition, the operation mode and start-stop frequency of the equipment must be clarified to provide a basis for the subsequent selection of pump type and structure.
The API610 standard is the core basis for the design and selection of volute pumps. Compliance verification should focus on the key technical requirements in the standard to ensure that equipment performance and quality meet the needs of industrial scenarios. The specific key points are as follows:
The implementation version of the API 610 standard should be determined in accordance with the project design specifications, as different versions have differences in technical requirements. For example, the 13th edition of API 610 has strengthened requirements for pump unit vibration control and bearing reliability. During selection, it is necessary to check the product technical documents to confirm that they clearly comply with all mandatory clauses of the corresponding version, so as to avoid compliance risks caused by version mismatch.
Performance verification should cover hydraulic efficiency, vibration limits, and sealing performance. The hydraulic efficiency must reach the minimum value specified in the standard; the vibration velocity of the bearing housing should meet the standard requirements corresponding to different rotational speeds; the sealing system should be selected based on the medium properties and a leakage test report compliant with the standard must be provided. In terms of materials, it is necessary to review the material certificates and test reports of key components to ensure that the composition and mechanical properties of materials such as flow-through parts and shafting meet the requirements of the standard and medium compatibility.
After clarifying the operating condition parameters and standard compliance, the stage of determining the pump type and comparing technical schemes begins. The core steps are as follows:
The selection of pump type and structure is based on the flow rate and head range to determine the pump type. For example, single-stage double-suction centrifugal pumps are preferred for large-flow and low-head operating conditions, while multi-stage centrifugal pumps are required for high-head operating conditions. At the same time, the installation method of the pump (such as horizontal or vertical) is determined based on the installation space and maintenance requirements.
The comparison of technical schemes should focus on efficiency, reliability, and economy, comparing product parameters, component service life, and after-sales service of different manufacturers. Product parameters include efficiency curves, required NPSH values, etc.; component service life involves the design life of bearings and seals; after-sales service covers the spare parts supply cycle and on-site commissioning capabilities. In addition, it is necessary to calculate the operating cost of the equipment, including energy consumption and maintenance costs, and select the scheme with the optimal whole-life cycle cost.
In conclusion, the selection of API610 hot oil pumps must strictly follow the standardized process of "parameter collation – standard matching – scheme comparison", and refined technical control should be implemented in each link.
