Abstract
The utility model discloses a water pump of a water turbine, comprising an engine seat and a water turbine which is arranged on the engine seat. The utility model is characterized in that the engine seat is also provided with the water pump; the rotating shafts of the water turbine and the water pump are fixedly connected or connected in a transmission way. The utility model is arranged at a position needing to throttle and reduce pressure in a circular water system; and the water turbine is designed according to water flow rate and pressure needing to be reduced in a pipeline, thus being capable of calculating the output rotating speed and power conveniently so as to select the water pump accordingly, realizing high-efficiency working of the water pump and achieving the purpose of saving energy.
Description
Technical field:
The utility model relates generally to a kind of water turbine water pump that is applied in the circulation.
Background technique:
In fields such as industry, agricultural, urban operating mechanisms, the place that much needs throttling, step-down is arranged in the circulation, as dropping valve, throttle valve, consumed many energy in vain; And above-mentioned dropping valve, throttle valve in a water passage circulation system, have the pipeline water pump to drive ducted current in the circulatory system often.
Patent double water pump (94110351.X) and patent double water pump (94215381.2) have been conceived a kind of double water pump, and this water pump adopts a kind of interrelated and centrifugal pump assemblying body independently, promptly are equipped with the opposite centrifugal pump of sense of rotation before the combination on same pump shaft.Liquid enters from the discharge opening of common centrifugal pump, and suction port flows out, and promotes the impeller counter-rotating, drives another pump work of just changing a job by rotatingshaft again.This double water pump plays a part of dynamic action in whole water passage circulation system, make can select low power power water pump for use in the circulation, reaches purpose of energy saving.But the Blade Design of centrifugal pump is power with the motor promotes current optimization, in double water pump, make the centrifugal pump reverse operation with the current promotion, efficient is extremely low, and be difficult to adjust output speed and power under its high efficiency, make water pump on rotating speed and power, be difficult to coupling, the inefficiency even the cisco unity malfunction that cause water pump so this patent is not made model machine for over ten years, more do not obtain promoting.
Technology contents:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of water turbine water pump is provided, the design of water turbine is the pressure design that reduces according to ducted water flow and needs, can reach very high efficient, water pump can be selected according to the parameter of water turbine, makes water pump to work under high efficiency.
The utility model is achieved through the following technical solutions:
The water turbine water pump includes support, and water turbine, water turbine are installed on the support, it is characterized in that also being equipped with on the described support water pump, and described water turbine is fixedlyed connected with the rotatingshaft of water pump or is in transmission connection.
Described water turbine water pump, the rotatingshaft that it is characterized in that described water turbine and water pump are same axle.
Described water turbine water pump is characterized in that the rotating speed of water turbine output and power and water pump are complementary.
The utility model has the advantages that:
The utility model is installed in the water circulation system, and current flow into from the water turbine ingress, and flows out from hydraulic turbine outlet, and current drive runner rotates the back and further drives the water pump rotation.The design of water turbine is the pressure design that reduces according to ducted water flow and needs, can reach very high efficient, and water pump is selected according to the running parameter of water turbine, makes water pump to work under high efficiency, thereby plays energy-conservation effect.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The water turbine water pump is combined by water turbine 1 and water pump 2, is installed on the same support, and the rotatingshaft of water turbine 1 and water pump 2 is same axle 3, go into water turbine 1 when flow of liquid, blade rotates blade in the impulse water turbine 1, and axle 3 rotates together simultaneously, and then drive water pump 2, make it just transfer to merit.
Claims (3)
1, the water turbine water pump includes support, and water turbine, water turbine are installed on the support, it is characterized in that also being equipped with on the described support water pump, and described water turbine is fixedlyed connected with the rotatingshaft of water pump or is in transmission connection.
2, water turbine water pump according to claim 1, the rotatingshaft that it is characterized in that described water turbine and water pump are same axle.
3, water turbine water pump according to claim 1 is characterized in that the rotating speed of water turbine output and power and water pump are complementary.
