Abstract
The invention discloses a directly-connected efficient built-in water turbine for a cooling tower. The directly-connected efficient built-in water turbine for the cooling tower comprises a water turbine body, a water inlet, a water outlet and an output shaft. A volute flow channel is formed in the outer side of the water turbine body, impellers are installed in the water turbine body, a plurality of fixed vanes are distributed in the water turbine body, the included angles between the center lines of the fixed vanes and a radial line which penetrates through the center lines are equal. Guide vanes of different numbers, sizes and ranking and combination forms are selected to change the proportion of the actual flow-passing surface at the entrance of a rotary wheel to the total flow-passing surface, therefore, the requirement of the water turbine for adapting to different flow-passing amount is met, and the influence on efficiency of the water turbine due to the fact that the guide vanes are moved to change angles is eliminated.
Description
Technical field
The present invention relates to water turbine, specifically belong to the efficient built-in water turbine of used for cooling tower direct connection.
Background technique
Mechanical-draft cooling tower is widely used in the industries such as iron and steel, chemical industry, uses in recent years water turbine for cooling tower to replace motor to drive blower fan of cooling tower to become a kind of trend to carry out reducing energy consumption.Low-specific-speed water turbine on market, due to the narrow limitation of existing Design of Hydraulic Turbine and type selecting, causes its efficiency lower now.Generate electricity with water turbine owing to will realizing regulating water-quantity and the effect of closing water, water turbine is provided with movable guide vane, realize controlling the inflow-rate of water turbine of water turbine and close water by the angle of regulating stator, the inflow-rate of water turbine maximum of this water turbine during central point that its guide vane ring all points to.Also changed the water (flow) direction of advancing runner when realizing regulating overcurrent, the angle of stator is only when certain best angle, and water turbine just can reach maximum efficiency.Under common running state, stator is not at best angle, and the efficiency of water turbine is all on the low side.
Summary of the invention
The present invention just is to provide the efficient built-in water turbine of a kind of used for cooling tower direct connection, the stator of selection varying number, size and different permutation and combination methods changes the ratio of actual flow-passing surface and total flow-passing surface of runner ingress, thereby realized that water turbine adapts to the needs of different inflow-rate of water turbines, eliminated due to the impact of movable guide vane Angulation changes on turbine efficiency.
Technological scheme of the present invention is as follows:
The efficient built-in water turbine of used for cooling tower direct connection, include turbine proper, water intake, water outlet, output shaft, the turbine proper outside is equipped with spiral casing flow passage, impeller is installed in turbine proper, be distributed with a plurality of stator blades in turbine proper, the center line of each stator blade is identical with the angle through between the radial line of central point.
Select the stator blade of varying number, size and different permutation and combination methods to change the ratio of actual flow-passing surface and total flow-passing surface of runner ingress, thereby realized that water turbine adapts to different inflow-rate of water turbines.
The efficient built-in water turbine of a kind of used for cooling tower direct connection that the present invention will provide, for a specific cooling tower, the stator of water turbine of the present invention adopts fixed, be constant at the peak efficiency angle, when design, the stator of selection varying number, size and different permutation and combination methods changes the ratio of actual flow-passing surface and total flow-passing surface of runner ingress, thereby realized that water turbine adapts to the needs of different inflow-rate of water turbines, eliminated due to the impact of movable guide vane Angulation changes on turbine efficiency.The present invention, because former movable guide vane has become fixed guide vane, has cancelled former fixed guide vane, makes the hydraulic turbine structure compact volume little.
The accompanying drawing explanation
The profile schematic diagram that Fig. 1 is water turbine;
The sectional drawing that Fig. 2 is water turbine of the present invention;
The various combination form that Fig. 3 is guide vanes of water turbine of the present invention.
