 Main structure

Impeller
The high efficiency impeller is designed by three dimensional flow theory which is calibrated by static and static balance after strict precision machining and passed the over speed test of 1.15 times the rated speed ensures the impeller strength . In order to meet the requirement of different working conditions of steam compressor, the impeller material can be titanium , duplex stainless steel and other materials .

Volute Casing
Using circular section volute, volute wall profile is designed to be log spiral lines, in line with the law of airflow movement, less impact on the blower . So the blower's flow efficiency is high, small vibration , low noise . Volute casing material can be 304,316L,2205,2507 stainless steel according to different working conditions .

High- speed Rotor
The high- speed rotor is consists of the impeller, the high - speed gear and the high - speed shaft. Impeller and high - speed shaft are connected by rod and the torque is transmitted by end surface pin or tooth . The dynamic balancing test accords to the international standards and the precision could reach G1 grade to ensure the operation to be smooth and reliable .

Gear
The acceleration gear pair adopts the involute tooth profile. The surface of gearwheel and pinion gets through the grinding and nitride- harden treatment to maintain the high speed stable operation ,low vibration and low noise . The lifetime can be 20 years .

Bearing
The high - speed shaft support. composed by many flexible pads , adopts tilting pad journal bearing . The pads could deflex around the fulcrum, its anti - vibration performance and automatically adjusting ability according to the variation of load and speed are both excellent .

Lubrication System

The lubrication system is consists of the oil tank and the oil pipeline . The pedestal doubles as a oil tank, the immersion - type electric heater and temperature control switch are both included in the oil tank. Lubrication piping is composed by : master oil pump , auxiliary oil pump, binocular filter and heat exchanger. The main oil pump would be driven by the low - speed gear and it supplies the pre- lubrication to gear and bearing with certain pressure when the units operate normally . The electric pump would supply the pre- lubrication before the units start and keep the oil pressure still under the emergency and downtime. The electric pump also plays a role of stand- by oil pump . The oil filter with double cylinder is high - precision .The pressure difference alarm device on filter is also equipped .

Seal
According to the requirements of working conditions, diverse options of sealing are available for the steam compressor , the standard options : labyrinth seal with steam purging, carbon ring sealing with steam purging ,dry gas seal , etc .

Sealing Steam Charging Device
Sealing Steam Charging Device is used for negative pressure or normal working condition steam compressor, it charges the superheated steam into shaft seal to prevent the air leakage into compressor. The steam charging device includes steam pressure relief valve, pressure detection device, stainless steel filter and etc. For steam compressors under positive pressure conditions, pressure relief methods such as blow-off or steam extraction are usually used to prevent exposed steam from entering the gearbox, resulting in emulsification of lubricating oil.

Desuperheating Water Spray Device
Annular distributed multiple high-pressure atomizing nozzles improve the distribution uniformity of water mist in the pipe and increase the atomization efficiency. When any individual nozzle is blocked or other abnormal conditions, the remaining nozzles can stil ensure sufficient spray volume. The inlet is equipped with a stainless steel pressure relief valve (manual or automatic option) and filter.

Drainage Tank
Used for collecting and discharging the liquid water generated from blower unit. It can be designed negative pressure, normal pressure or positive pressure three modes as per actual requirement. Tank body is equipped with inlet valve (manual or automatic option), sight glass, liquid level gauge (local or remote transmission) and drainage valve and etc accessories. If it is equipped with automatic drainage valve or drainage pump (negative pressure condition) and remote transmission liquid level gauge, automatic drainage, real-time monitoring of liquid level, abnormal alarm and other functions can be realized.

Synchronous Motors And Drives

Motor
Recommend to use permanent magnet synchro- nous motor of high efficiency meets the grade 1 energy efficiency grade of GB30253-2013 standard . Its rated operating efficiency is 94.5-97%,4-6% higher than asynchronous motor . Simple structure , smaller size, lower noise , better energy saving performance .

Monitoring And Control System

The monitoring and control system are designed for protecting running of high - speed centrifugal blower . The startup is provided with the mode of interlock , anti - surge control ,the accessorial pump automatic start & stop according to the oil pressure , protection for over high bearing temperature and vibration . There are oil pressure sensors on oil - supplying pipeline, oil temperature sensors following oil coolers, temperature sensors and vibration sensors on high speed sliding bearings . The inlet and outlet pipeline are equipped with primary & secondary meters and transmitter to measure air tempera- ture & pressure , so that, it can monitor the parameters real - time, to ensure the safe , stable and reliable operation of the blower .

Choose  steam compressors for an efficient, reliable, and quiet steam management solution that meets the demands of modern industrial settings.
