Horizontal double casing barrel pump (API610 BB5) Lift:～3500m Flow:～850m³/h

Product Overview

1. With double-casing structure and center line support, it is not necessary to dismantle outlet pipeline to fast dismantle and install components of rotor with special tools. Besides, with cone axial design of coupler end, it is convenient in equipment overhaul and maintenance.
2. Packaging-type mechanical seal is adopted according to seal design of API682 standard. It is
   convenient in installation and maintenance. The axial compression is free of influences of axial dimensions of any connecting pieces. It is not necessary to make adjustment.
3. Carbon steel bearing housing, with fan cooling, adopts new non-metallic synchronous oil-slinging ring, which makes lubrication more sufficient and reduces lubricating oil pollution; equipped with special bearing gland, it can meet the dual needs of oil mist and oil bath lubrication.
4. By optimizing axial structure and selecting ball-ball and sliding-
   ball and sliding-thrust bearing forms, the optimal support can be provided for parts of rotor and the cost for bearing and support system can be maximally reduced. 5. The outer cylinder is forged, the pipe mouth
   is designed according to the API standard triple load, and the
   API standard base is adopted to ensure safe, stable and reliable operation. 6. Impeller is excessive interference fi and axial restraint, perturbation caused by assembling clearance when high-speed revolution can be eliminated. 7. With
   enhancement rigid stepped shaft (dead band can be used according to the requirement) optimized and designed according to hydraulic performance, power transmission requirement can be satisfied and rotor's reliability can be enhanced and typical design scheme of API610 can be satisfied. 8. The impellers are arranged back to back and are equipped with intermediate bushings and throat bushings. The optimal structure balances the axial force and reduces the cost of bearing components. Impellers are back-to-back arranged with middle and throat bushing, optimal structural balancing axial force can be realized and cost for bearing parts can be reduced. 9. XBB5- standard, single-suction impeller, back-to-back arranged. XBB5D-first-stage impeller double-suction structure enhances anti-cavitation capacity and reduces suction specific speed .
