Audited Supplier
The T530 steam turbine is a single - stage back - pressure steam turbine. It has a velocity - compounded stage impeller with an impeller pitch circle diameter of 800 millimeters. The rated speed of the main shaft is 3000 revolutions per minute, and the power range is 300 - 1500 kW. A gearbox can be installed according to user requirements to achieve speed change. The main feature of this model is to use superheated steam as the steam source to drive rotating machinery to do work, realizing the cascade utilization of energy to achieve the purpose of energy conservation and consumption reduction.

Emergency Shut-off Device
The emergency shut-off device is a protective mechanism that prevents the rotor from exceeding the allowable rotational speed, installed on the main oil pump casing connected to the main shaft. The emergency shut-off device used in this unit is a centrifugal flyweight type, which has an eccentric weight mounted radially on the main oil pump casing. At normal rotational speeds, a spring force balances it. When the unit's speed exceeds the rated speed by 9-11%, the flyweight is thrown out, causing the emergency shut-off throttle to disengage and activate.
Provide guidance for equipment installation and commissioning; conduct technical training; during the warranty period, if the unit fails to operate normally or components are damaged due to quality defects, the Seller shall repair them free of charge.
Warranty Period: One year.
