1. Double-shell structure with central-line support; no need to dismantle the inlet and outlet piping; quick assembly and disassembly of the rotor components can be achieved with special tools, and the coupling end features a tapered shaft design for easy equipment maintenance and repair.
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. Designed with a sealing chamber according to API 682 standards, featuring a modular mechanical seal for easy installation and maintenance. Axial compression is unaffected by any connecting part's axial dimensions, no adjustment required.
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, featuring a new non-metallic synchronous throw-off oil ring for more thorough lubrication and reduced oil contamination. Comes with a dedicated bearing cover to meet both oil mist and oil bath lubrication requirements.
With carbon steel bearing casing, fan cooling, and with new-type non-metal synchronic oil slinger, it is further sufficiently lubricated and pollution of lubricating oil is reduced. With special bearing gland cover, dual requirements of oil mist and bath lubrication can be satisfied.
4. Optimize bearing structure by selecting forms such as ball/ball, sliding/ball, and sliding/stop thrust bearings, providing support to the rotor components while reducing the cost of the bearing and support system.
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 and machined, with pipe ends designed for triple the API standard load. It features an API-standard base, ensuring safe, stable, and reliable operation.
Outer barrel is forged and processed. Pipe orifice is designed according to API standard twofold load. API standard chassis is adopted to ensure safe, stable and reliable operation.
6. The impeller is designed with interference fit and axially fixed to eliminate deflection caused by assembly gaps during high-speed rotation.
Impeller is excessive interference fi and axial restraint, perturbation caused by assembling clearance when high-speed revolution can be eliminated.
7. Forged reinforced rigid step shafts optimized for hydraulic performance (with hollow sections available as needed), meeting power transmission requirements, enhancing rotor reliability, and conforming to the typical design scheme of API 610.
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. Impellers are arranged in back-to-back configuration, featuring an intermediate bushing and throat bushing. This design balances the axial forces and reduces the cost of the 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 type, single suction impeller, arranged in back-to-back configuration.
XXB5-standard, single-suction impeller, back-to-back arranged.
XBB5D - Primary impeller with double suction structure, enhancing anti-cavitation capability and reducing the suction speed ratio.
XBB5D-first-stage impeller double-suction structure enhances anti-cavitation capacity
and reduces suction specific speed.
