AY centrifugal oil pump structure

I. Product Overview AY centrifugal oil pump is based on the AY centrifugal oil pump based on the American Institute of Petroleum Industry Standard API 610 8th Edition and designed and modified, product type, installation size and performance parameters to maintain the same with the AY centrifugal pump, there are Facilitate the renovation of the device. In order to adapt to different operating conditions, this type of pump body adopts central support; the bearing body can be selected from natural heat dissipation, air cooling and water cooling; the flow-through components are made of cast iron (I), cast steel (II), and horse. Type of stainless steel (III) three; pump structure has a single-stage single-suction, two-stage single-suction, single-stage double-suction, multi-stage and other forms. The implementation of GB3215-82 "General Technical Conditions for Centrifugal Pumps for KGT Chemicals and Petrochemical Processes" can be used for mediums with certain viscosity that do not contain solid particles such as petroleum and chemical products with a medium temperature of not more than 450°C.

Second, the product features 1, the standard requirements are high: AY pump in strict accordance with the American Petroleum Institute API610 latest version 8 requirements for retrofit design, higher than the original API 610 version 6 standard.

2. High-temperature resistant structure: The pump body adopts a central support structure to prevent the stress concentration and deformation of the pump body caused by the creep of the material under high temperature. The support frame, pump cover, suspension, and bearing parts all have a cooling chamber.

3, diaphragm coupling: small size, light weight, large carrying capacity, high transmission efficiency, high transmission accuracy, suitable for high and low temperature oil and water occasions. The elongated structure ensures that the motor does not have to be moved and the lines are removed during maintenance.

4. Mechanical seal: Single-end machine seal, double-end machine seal and metal bellows machine seal can be selected according to different working conditions, and the seal is reliable.

5. Bearing: The bearing adopts single-row radial bearing and two-row thrust bearing pairing, bearing capacity is large. Long design life (>25,000 hours), lubricated oil lubrication.

6. Fully sealed shaft: seals and “O” ring seals are used on the shaft to ensure that the shaft does not contact the media and increase the life of the shaft.

7, high balance accuracy: Rotor parts dynamic balance accuracy of G1.0 level.

Third, the working conditions <br> <br> flow: 9m3 / h ~ 500 m3 / h ( water state)

Head: 38m to 650 m (clear water state)

Medium temperature: -45°C～+450°C

Ambient temperature: ≤+40°C
