The AY centrifugal pump is a redesigned and upgraded version of the original AY pump, based on the American Petroleum Institute (API) standard API 610, 8th edition. The product type, installation dimensions, and performance parameters remain consistent with the original AY pump, making it an ideal choice for equipment upgrades. To adapt to various operating conditions, the pump offers different configurations, including central support for the pump body, optional cooling methods such as natural cooling, air cooling, or water cooling, and three types of impeller materials: cast iron (Type I), steel (Type II), and stainless steel (Type III). The pump can be designed in single-suction, double-suction, or multi-stage configurations, offering flexibility for different applications.
This pump complies with GB 3215-82 "General Technical Conditions for Centrifugal Pumps in Chemical and Petrochemical Processes," and is suitable for transporting media with temperatures up to 450°C, provided that the medium is free from solid particles and has a certain level of viscosity. It is commonly used in the petroleum and chemical industries.
Key features of the AY centrifugal pump include:
1. **High Standards**: The pump is designed in strict compliance with the latest API 610, 8th edition, surpassing the previous API 610 version 6 standards in terms of quality and performance.
2. **High-Temperature Design**: The central support structure of the pump body helps prevent stress concentration and deformation caused by high-temperature creep. Cooling chambers are integrated into the support frame, pump cover, suspension, and bearing parts for enhanced thermal management.
3. **Diaphragm Coupling**: This coupling offers a compact design, lightweight, high load capacity, and efficient power transmission. It is suitable for both high and low temperature environments, and its extended structure allows for easy maintenance without moving the motor or removing pipelines.
4. **Mechanical Seals**: A variety of mechanical seal options are available, including single-end, double-end, and metal bellows seals, ensuring reliable sealing performance under different operating conditions.
5. **Bearings**: The pump is equipped with a single row of radial bearings and two rows of thrust bearings, providing strong load capacity and long service life (>25,000 hours). Lubrication is done via thin oil, ensuring smooth operation.
6. **Fully Sealed Shaft**: The shaft is sealed using both a shaft seal and O-ring seals, preventing direct contact between the shaft and the medium, thus extending the shaft’s lifespan.
7. **High Balance Accuracy**: The rotor is balanced to G1.0 level, ensuring stable and vibration-free operation even at high speeds.
**Operating Conditions**
- Flow: 9 m³/h to 500 m³/h (in water conditions)
- Head: 38 m to 650 m (in water conditions)
- Medium Temperature: -45°C to +450°C
- Ambient Temperature: ≤ +40°C
This pump is well-suited for demanding industrial applications where reliability, efficiency, and durability are essential. Its advanced design and versatile configuration make it a preferred choice for modern chemical and petrochemical processes.
