The T710 steam turbine is a multi - stage condensing steam turbine. The unit is arranged in a single layer, featuring a small volume and convenient installation. This steam turbine adopts multi - valve regulation and forced lubrication, with the rated speed of the main shaft being 3000 revolutions per minute. The rotor is a shrunk - on rotor, consisting of 8 impellers. The structure combination of the flow passage part can be flexibly designed according to users' parameters and requirements. The T710 is a condensing unit for waste heat power generation that can use superheated new steam or saturated steam. The exhaust steam is condensed into water in its built - in condenser. Two fully automatic main steam valves can be installed for the main steam valve. When the inlet steam parameters are low, the maximum steam inlet flow can reach 40T/h, which can meet the waste heat power generation requirements of enterprises rich in waste heat steam. The equipment has a lower operation cost and more significant economic benefits.

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.
