Problems solved by technology

In this patent, due to the configuration of the casing at the impeller, when the water flows through the impeller, a vortex will be formed on both sides of the main flow of the water flow from the water inlet to the water outlet area. The eddy currents create mutual turbulence that hinders the work done by the water flow, thereby reducing the efficiency of the turbine
In addition, since there are deflectors and diverter blocks in the water diversion chamber of the water inlet area, the water inlet resistance will increase and the efficiency of the turbine will also be reduced.

Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] see figure 1 and figure 2 , the double-clicking frog-like water turbine of the present invention includes a casing 1, a main shaft 2, a bearing 3, an impeller 4 and a base 5 for supporting the casing 1, and the impeller 4 is sleeved on the main shaft 2. The casing 1 is provided with a diversion chamber 11 , a water inlet 12 , a vortex chamber 13 , a water outlet 14 and a draft tube 15 . The size of the water inlet 12 and the water outlet 14 should be proportional to the water inlet velocity. The water introduction chamber 11 introduces the water flow into the water inlet 12 . The water diversion chamber 11 is arranged on one side of the casing 1 and is surrounded by a shroud 112 . The shroud 112 acts as a deflector, so that the water flowing into the water inlet 12 has a flow direction without impinging on the blades of the impeller 4 . The deflectors and d...

Abstract

The present invention discloses a cross-flow turbine. It includes machine shell with water inlet, water outlet, water-feeding chamber and tail water pipe, main shaft, bearing, base seat for supporting machine shell and impeller cover-mounted on the main shaft. Said impeller is placed in the machine shell interior. Said cross-flow turbine also includes a turbulence cavity, said turbulence cavity is positioned between water inlet and water outlet.

Description

technical field [0001] The invention belongs to the technical field of water supply and drainage for refrigeration and air conditioning, and in particular relates to a universal water turbine for cooling towers. Background technique [0002] Existing cooling towers generally use electric motors to drive fans to extract air. The disadvantages are high noise and high power consumption. The annual electricity bill consumed by the motor is equivalent to the cost of purchasing a new cooling tower. For this reason, the present inventor has designed a kind of cooling tower water turbine to replace the electric motor and the speed reducer of existing cooling tower, see CN2530233Y Chinese invention patent specification of announcement on January 8th, 2003. In this patent, due to the configuration of the casing at the impeller, when the water flows through the impeller, a vortex will be formed on both sides of the main flow of the water flow from the water inlet to the water outlet ar...
