Abstract
The utility model discloses a non-overloading tangential pump, comprising a tangential pump, a special-purpose valve, and a pedestal. The tangential pump consists of a motor and a pump body. The motor and the pump body are connected through a shaft coupling. The pump body is provided with a stand which is fixed on the pedestal. The pump body comprises a water inlet, a water outlet, and an impeller. The special-purpose valve is mounted on the water outlet of the pump body. The non-overloading tangential pump is capable of restricting the quantity of flow of the pump within a preset scope, thereby effectively protecting the motor.
Description
Technical field
The utility model relates to a kind of water pump.
Background technique
Water is the most important living resources of people, in domestic water, production feedwater or fire supply, all need to use water pump, no matter and be to cistern water supply, or supply water to gas pressure water tank, or directly to supplying water with drainage facility, because purposes is different, demand is different, therefore should select different dedicated pumps.
And tangent pump is as the dedicated pump of fire supply, it is divided into vertical and horizontal two kinds, its maximum characteristics are that flow～head curve is very smooth, namely in the full flow scope, lift changes little, when pump duty changes in the required peak rate of flow scope from zero, its lift changes in 5%, and superpressure not when small flow or zero delivery, thereby the phenomenon of having avoided Ordinary Centrifugal Pumps not supply water when superpressure and large flow during small flow in the fire-fighting scene has improved fire-fighting efficiency and fire personnel's safety reliability greatly.
But tangent pump existent defect in the prior art is namely when running into the condition of a fire, because the situation is critical, when fire hydrant water supply system and automatic sprinkling system shared fire service pump, the water yield exceeded preset flow, the motor overload running then is easy to cause burn-down of electric motor for a long time.
The model utility content
The utility model discloses a kind of nonoverload tangent pump, its flow that can limit pump in preset range, thereby effectively protect motor.
Nonoverload tangent pump of the present utility model comprises tangent pump, special valve and base; Tangent pump comprises motor and the pump housing, and motor is connected with the pump housing; The pump housing is provided with support and is fixed on the base; The pump housing includes the mouth of a river, water outlet and impeller; Special valve is installed on the water outlet of the pump housing.
In a preferred embodiment, connect by coupling between motor and the pump housing.
In a further advantageous embodiment, motor is horizontal the connection with the pump housing.
In a further advantageous embodiment, motor is vertical the connection with the pump housing; At this moment, impeller is multi-stage impeller or single-stage impeller.
Description of drawings
Fig. 1 is the structural representation of nonoverload tangent pump of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, nonoverload tangent pump of the present utility model is further described.
As shown in Figure 1, nonoverload tangent pump 1 of the present utility model comprises tangent pump, special valve 6 and base 7.Tangent pump and special valve 6 all are positioned on the base 7, form integral device.
Tangent pump comprises motor 2 and the pump housing 3.
The pump housing 3 is provided with support 5 and is fixed on the base 7.
In one embodiment, motor 2 is horizontal the connection with the pump housing 3.
In another embodiment, motor 2 is vertical the connection with the pump housing 3.When motor 2 was vertical the connection with the pump housing 3, impeller can be multi-stage impeller or single-stage impeller.
The pump housing 3 includes the mouth of a river 8, water outlet 9 and impeller.Water sucks via water inlet 8 and connects the pump housings 3, pass through vane rotary again after, from water outlet 9 guttations.
Special valve 6 is installed on the water outlet 9 that connects the pump housing 3.
Under the prerequisite of default pump head point, special valve 6 keeps fully unimpeded and nonintervention when being lower than the setting flow automatically; And surpassing under the operating mode of setting flow; then flow or the lift of pump are controlled; make its flow be returned to the flow of setting, can not use and burn because super flow or overload occurring to guarantee motor 2, guaranteed that therefore nonoverload tangent pump 1 needn't shut down and work safely continuously.
The all parts of nonoverload tangent pump of the present utility model preferably adopts stainless steel or aluminum alloy to make.
More than describe the utility model nonoverload tangent line pump structure in detail by embodiment; but those skilled in the art can therefrom obtain the technology enlightenment in the scope that does not break away from invention spirit; it is carried out various combinations and modification, and therefore protection domain of the present utility model is as the criterion with claims.
