Abstract
The utility model discloses an internal efficient direct acting water turbine for a cooling tower. The water turbine comprises a water turbine body, a water inlet, a water outlet and an output shaft, wherein a volute runner is arranged outside the water turbine body; an impeller is arranged in the water turbine body; a plurality of fixed blades are distributed in the water turbine body; included angles between the centerlines of the fixed blades and a radial line penetrating through a center point are the same. According to the water turbine, different numbers of guide blades with different sizes are arranged in different ways to change the proportion of an actual flow-passing surface to a total flow-passing surface at an inlet of a rotating wheel, so that a requirement on the adaptability of the water turbine to different flow rates is met, and the influence of changes in angles of movable guide blades on the efficiency of the water turbine is eliminated.
Description
Technical field
The utility model relates to water turbine, specifically belongs 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, by regulating the angle of stator to realize, control the inflow-rate of water turbine of water turbine and close water, during central point that its guide vane ring all points to, the inflow-rate of water turbine of this water turbine is maximum.When realizing adjusting overcurrent, also changed the water (flow) direction of entering runner, 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 utility model is just 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 the needs that water turbine adapts to different inflow-rate of water turbines, eliminated due to the impact of movable guide vane Angulation changes on turbine efficiency.
The technical solution of the utility model 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, turbine proper outside is provided with spiral casing flow passage, impeller is installed in turbine proper, in turbine proper, be distributed with a plurality of stator blades, the center line of each stator blade is with identical through the angle between the radial line of central point.
The stator blade 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 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 utility model will provide, for a specific cooling tower, the stator of the utility model water turbine adopts fixed, be constant at peak efficiency angle, in when design, select the stator of varying number, size and different permutation and combination methods to change the actual flow-passing surface of runner ingress and the total ratio of flow-passing surface, thereby realized the needs that water turbine adapts to different inflow-rate of water turbines, eliminated due to the impact of movable guide vane Angulation changes on turbine efficiency.The utility model, because former movable guide vane has become fixed guide vane, has been cancelled former fixed guide vane, makes hydraulic turbine structure compact volume little.
