Single stage high speed centrifugal blower
The single-stage high-speed blowers produced by Shandong Four seawater treatment Equipment Co., Ltd. are mainly divided into D and GS two series, respectively using energy efficient motor + speed box and high-speed motor direct drive two structures, each with its own characteristics. All series of impellers and volutes are designed, analyzed and simulated with NREC professional software, which has efficient aerodynamic performance and ultra-high stable reliability.
1, impeller line advanced, high efficiency
The impeller is designed by three-way flow theory, and the performance of the blower is verified by computer flow analysis technology after three-dimensional software modeling, so that the variable efficiency of the single-stage high-speed centrifugal blower is as high as 85%.
2, wide flow adjustment range, can be applied to a variety of working conditions
The fan adopts axial inlet guide vane and diffuser adjustment device, and the flow adjustment range is 60% ~ 110% of the rated flow rate, so that it has high efficiency in non-rated operating conditions. The anti-surge device can effectively avoid the surge of the blower.
3, the fan structure is compact, small volume
The blower body is assembled on the shell of the gear growth box, and the lubricating oil system, motor and gear growth box are compact arranged on the common base, and the base serves as the fuel tank to achieve the overall delivery; The on-site installation is safe and convenient, and the commissioning cycle is short.
4, the rotor after strict dynamic balance, small vibration, high reliability, low overall noise
The impeller is made of forged aluminum alloy and finished by machining center. The rotor has a small moment of inertia, and the unit has a short start and stop time, without high fuel tank and accumulator. Compared with multistage centrifugal blowers with the same flow and pressure, it has low energy consumption, light weight and small footprint.
5, the fan structure is advanced and reasonable, less wearing parts, easy installation, operation and maintenance
Bearing vibration temperature rise, fan inlet and outlet pressure, temperature, anti-surge control, starting interlock protection, fault alarm, lubrication system oil pressure, oil temperature control are all controlled by programmable logic, so that the whole machine operation can be monitored in real time. The whole machine has no wearing parts, easy daily maintenance.
