Description
Technical field
The utility model belongs to the pump technology field, relates to a kind of large pump.
Background technique
Water pump is the machinery of carrying liquid or making the liquid supercharging, and water pump is widely used in daily life and industrial production, and existing water pump commonly used is Centrifugal water pump.One comprises impeller, motor and the pump housing Centrifugal water pump, and the output shaft of motor passes the pump housing and is connected with the impeller that is positioned at the pump housing.The working principle of Centrifugal water pump is as follows: the driven by motor vane rotary, the water intake of water from the pump housing sucked in the pump housing, and be displaced into the water outlet of the pump housing.Wherein active is impeller, the blade rotary of impeller, water is driven under centrifugal action to throw away to the inwall of the pump housing by blade again and flows out from water outlet, water in the pump housing is after throwing away, new current enter under atmospheric pressure in the pump housing again, and water continuously enters from water intake again and discharges from water outlet like this.But this water pump needs to fill first water in the pump housing before startup.If do not fill water, impeller can only drive the air rotation, because the per unit volume quality of air is very little, the centrifugal force that produces is just very little, and is unable with in the pump housing and the Bas Discharged in the water outlet, can not form vacuum in the pump housing, water also just can not suck, and water pump can't work.But after existing water pump added entry, because also water pump inner chamber connection of intake pipe, water can flow in the intake pipe, the power of small pump is less, even can not produce considerable influence to its working effect after current fall yet, but for large-scale water pump, after water flowed away, water pump just can't work.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the large pump that a kind of using effect is good, flow is large.
The purpose of this utility model can realize by following technical proposal:
A kind of large pump, comprise base, be located at its inside on the base have the pump housing of cavity and be located in this cavity by motor-driven impeller, the described pump housing is provided with water intake and the water outlet that is communicated with this cavity respectively, described water outlet is positioned at the top of this pump housing, the top of described water outlet has the filler that is communicated with above-mentioned cavity, be provided with plug in the described filler, it is characterized in that, the inner of described water intake is hinged with the water shutoff plate for the sealing water intake, the bottom of described water shutoff plate is resisted against on the step of being located on the pump housing, and the diameter of described water intake is 4-6 cun.
The water intake size of this water pump is larger, and the flow of water pump is large.When the water pump off-duty, open the plug on the filler, water is added in the cavity, because the existence of water shutoff plate, water can not enter in the water intake.During electric machine rotation, impeller is rotated, and impeller will be positioned at the water of cavity and take water outlet out of, and under the effect of centrifugal force, the water shutoff plate is opened, and the water in the water intake enters in the cavity.
In above-mentioned large pump, have the joint one that radially outward protrudes on the outer end of described water intake, described joint one is provided with attachment hole one, is equipped with connecting bolt one in the described attachment hole one.
Water intake is docked with intake pipe, fixing by bolt one, be connected on the water intake convenient by spinning than intake pipe.
In above-mentioned large pump, also be provided with the joint two that radially outward protrudes on the outer end of described water outlet, described joint two is provided with attachment hole two, is equipped with connecting bolt two in the described attachment hole two.
Water outlet is docked with outlet pipe, fixing by bolt two, be connected on the water outlet convenient by spinning than outlet pipe.
In above-mentioned large pump, the diameter of described water intake is 6 cun.
In above-mentioned large pump, described water shutoff plate is in the form of annular discs, and the diameter of described water shutoff plate is greater than the diameter of water intake.
Compared with prior art, this large pump has the following advantages:
The flow of this water pump is large, uses and goes to injected water in the pump housing, and the water shutoff plate of increase can prevent that water from flowing in the water intake, thereby guaranteed that water can enter in the pump housing in water intake, good stability, reliability are high, and water outlet and intake pipe are easy to connect, and water outlet and outlet pipe are easy to connect.
