Problems solved by technology

[0003] However, the existing water turbines are not suitable for cooling towers. Since the water inlet pressure of cooling towers is generally less than 0.1 MPa, the water pressure required by various water turbines is generally higher.
The structural forms of axial flow and mixed flow turbines are difficult to apply to cooling towers. Tubular turbines can be applied structurally due to their large flow and small pressure head, but their vibrations often make it difficult to eliminate noise, and their efficiency is low. Low, often can not meet the requirements of the old old cooling tower to cancel the motor and not increase the water pump lift during the transformation

Embodiment Construction

[0018] 1 and 2 , a general-purpose water turbine for a cooling tower of the present invention is equipped with a casing 1 , a main shaft 2 , a bearing 3 and an impeller 4 , and the impeller 4 is arranged on the main shaft 2 . The casing 1 is provided with a water inlet 11 and a water outlet 12 . The casing 1 is provided with a water outlet area 13, and the water outlet area 13 must satisfy the slow release space. The whole machine cancels the motor and reducer.

[0019] The bearing 3 is composed of an upper bearing 31 and a lower bearing 32, and is supported by a bearing seat 5, and the bearing seat 5 is connected with the bearing seat cover plate 6 into one body. A sealing ring 7 is installed at the connection with the main shaft 2 to prevent the leakage of circulating water.

[0020] The impeller 4 is arranged at the water inlet 11 . The number of blades of the impeller 4 is more than seven, and can reach nineteen or more. On the radial plane of the impeller 4, the gener...

Abstract

This invention relates to a general water-turbine of a cooling tower including a case with inlet and outlet, a mainshaft, bearing and a blade wheel mounted on the mainshaft, a delivery zone in the case. The invention eliminates motor and reducing device. The blade wheel is set at the inlet, its intale direction on the sagitted plane is on the same line with the delivery, and strikes the blade wheel in water post geometric shape crossing that of the inlet and slowly releases at the delivery zone after breaking through the impeller to rotate blades and flow out through the outlet.

Description

technical field [0001] The invention belongs to the technical field of water supply and drainage of refrigeration and air conditioning, and particularly relates to a general water turbine for a cooling tower. Background technique [0002] Existing cooling towers generally require a fan to draw air, and the fan is driven by a motor, and some are associated with a reducer, but it is difficult to eliminate the mechanical noise generated. Furthermore, the electricity consumed by the motor can be used for a year to purchase a cooling tower corresponding to the amount of water treated. [0003] However, the existing turbines are not suitable for cooling towers. Since the inlet water pressure of cooling towers is generally less than 0.1MPa, most of the water pressures required by various turbines are relatively high. The structural forms of axial-flow and Francis-turbines are difficult to apply to cooling towers. Tubular-flow turbines are structurally applicable due to their large...
