Product Description

The C810 steam turbine is a multi-stage back-pressure high-temperature, high-pressure unit featuring a single-deck layout for compact dimensions and easy installation. It employs multi-valve regulation with forced lubrication and operates at a main shaft speed of 3000 rpm. The rotor is an integral forged design. Utilizing a dual-cylinder configuration with inner and outer cylinders, the unit delivers high efficiency, low operating costs, and significant economic benefits.

Structural Features

● Structure: Quick-mount double-pivot multi-stage back-pressure steam turbine

● Layout: Single-deck arrangement

● Mechanical speed control: Fully hydraulic speed control

● Electronic speed control: DEH

● Overspeed Protection: Dual mechanical fly-hammer systems with electromagnetic valve electronic intelligent control

● Steam Seal Type: Stainless steel labyrinth steam seal

● Main Steam Valve: Integrated automatic main steam valve (with quick-closing combination device)

● Main Shaft Assembly: Integral forged rotor

● Lubrication System: Forced oil lubrication with oil thinning station and cooler

● Thermal Expansion Compensation: Sliding thermal compensation for front bearing support
