Generally, hydro turbine includes following kinds:
1. Reaction turbine:
1.1 Francis turbine/mixed-flow turbine
1.2 Axial turbine
1.3 Tubular turbine/through flow turbine
1.4 Diagonal turbine: Deriaz turbine, fixed blade of Deriaz turbine
2. Impulse turbine/action turbine:
2.1 Pelton turbine/scoop turbine
2.2 Inclined jet turbine/angular impulse turbine/Turgo impulse turbine
2.3 Cross-flow turbine
3. Pumped Storage Hydroelectric Generating Sets
Francis turbine/mixed-flow turbine
Horizontal Francis Turbine& Vertical Francis Turbine
Francis turbines/mixed-flow turbines are widely used in high, medium and low water heads, ranging from 20m to 400m, with capacities ranging from dozens of KW to several hundred thousand of KW, making them the most widely used models. Horizontal Francis turbines/ mixed-flow turbines usually used in small capacity, and vertical ones in medium and large capacity.

TURBINE TYPE
e.g. HLD294-LJ-340
HL—Francis turbine (ZZ for Kaplan; ZD for axial-flow type with fixed blades; GZ for bulb type; CJ for Pelton type);
D294—Runner code;
LJ – Vertical, metal spiral case (WJ for horizontal, metal spiral case; LH for vertical concrete spiral case; WP for horizontal bulb type; WZ for horizontal, shaft-extension tubular type);
340 – Runner diameter, in centimeters;
GENERATOR TYPE
e.g. SF90-28/6800
SF— Vertical hydro-generator (SFW for horizontal hydro-generator; SFWG for horizontal bulb type hydro- generator);
90— Rated generator output, in MW or KW;
28— Number of poles;
6800— Outer diameter of stator core, in millimeters.
