Product Overview

Configuration Advantages

Air suspension bearing

Use high-speed rotating centrifugal force to suspend itself; Simple structure without auxiliary devices such as lubricating oil supply- The work is non-contact and does not need maintenance and repair; No vibration of bearing; Start / stop durability guarantee, 40000 tests through on / 0ff test.
Three dimensional flow wheel

High compression efficiency, novel three-dimensional structure design; High anti surge stability, strong bearing capacity and overload capacity of 120%;
It is made of high-strength forged aluminum alloy al7075 and precision manufactured by 5-axis machining center to adapt to the harsh working conditions of high temperature and high pressure; The surface is subject to anti-oxidation and anti-corrosion treatment
High speed motor
High efficiency permanent magnet synchronous motor (PMSM) is adopted, with efficiency ≥ 96%; Compact overall dimensions; It can realize accurate speed regulation; The motor shaft is directly connected with the impeller, and the transmission efficiency is 100%; Insulation grade is h (maximum temperature resistance 170 ° C); Number of motor poles: 2 poles; The suitable power supply is AC380V / 50Hz.
controller
Control module suitable for centrifugal blower; Start the turbo switch, and the Chinese display touch screen shall be equipped once; Load shutdown has powerful man-machine data exchange channel: communication interface with upper computer is provided; Set anti surge protection measures for old errors in operation to ensure the safe use of the equipment; Sye 5 tb125 provides a variety of operating modes.
Motor cooling system
According to the heating capacity of the motor under different loads, high-efficiency motor cooling technology is adopted: forced air cooling is adopted below 300hp (including), and internal circulating water cooling is adopted above 300hp.
