Description
Technical field
It the utility model is related to centrifugal pumping apparatus technical field, and in particular to a kind of anti-whirlpool centrifugal pump inhalation part.
Background technology
Pump, it is a kind of to increase the pressure of liquid or gas, the machinery of transport flow is allowed to, is that one kind is used for moving liquid
The device of body, gas or specialized fluids medium, it is the machinery of convection body work done.It is natural that the heart of the mankind and animal, which can be said,
Pump, blood is transported to body various pieces by it.
At present, before centrifugal pump starts, pump and water inlet pipe are first filled into water, after pump operation, impeller at a high speed rotation and produce
In the presence of raw centrifugal force, the water in impeller channel is thrown toward surrounding, is pressed into spiral case, and impeller eye forms vacuum, pond
Water is inhaled into supplemented with this space under external atmospheric pressure along suction hose.Then the water sucked is thrown away through spiral case by impeller again
And enter outlet pipe.As can be seen here, if centrifugal pump impeller constantly rotates, it can continuously absorb water, press water, water can be continuously
Raised from lower to eminence or a distant place.In summary, centrifugal pump is due to the work of centrifugal force caused by the high speed rotation in impeller
Under, water extraction is raised to eminence.The centrifugal pump of prior art, due to needing impeller, rotation produces centrifugal force at a high speed, unavoidably
, the current in runner can also follow impeller to rotate on startup, form whirlpool, and whirlpool center is hollow, is easily caused
Pump housing water absorption reduces, and does not reach requirement, centrifugal pump abnormal wear is also resulted in when serious.
The content of the invention
The purpose of this utility model is：For prior art centrifugal pump when in use, due to need impeller at a high speed revolve
Change the line of production raw centrifugal force, inevitably, the current in runner can also follow impeller to rotate on startup, form whirlpool, and whirlpool
Center is hollow, easily causes the reduction of pump housing water absorption, does not reach requirement, and centrifugal pump is also resulted in when serious and is damaged extremely
The problem of consumption, there is provided a kind of anti-whirlpool centrifugal pump inhalation part, can effectively change the fluid flow pattern of centrifugation Pump Suction Nozzle, prevent whirlpool
Volute into, improve centrifugal pump water suction stability.
The technical solution adopted in the utility model is as follows：
A kind of anti-whirlpool centrifugal pump inhalation part, including filter mantle, mounting plate, center flow channels, bottom plate, the mounting plate
Filter mantle upper and lower end parts are connected to bottom plate, the center flow channels are fixed on the axis of filter mantle.
Preferably, the utility model also includes multiple vertical reinforced bar parts for being used to improve filter mantle intensity, it is described perpendicular
The inside circumference of filter mantle is distributed on to reinforcing member, the both ends of vertical reinforced bar part are fixed with mounting plate and bottom plate respectively；
Preferably, the utility model also includes being used for the horizontal reinforcing member for consolidating center flow channels, the horizontal reinforcement
Rod member is equidistantly connected between center flow channels and vertical reinforced bar part.
Preferably, the also horizontal connection of the inside of the center flow channels has the filter core for filtering out solid impurity in runner.
Preferably, the center flow channels are in up-small and down-big horn-like.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, due to needing impeller, rotation produces centrifugal force at a high speed, and inevitably, the current in runner also can on startup
Follow impeller to rotate, form whirlpool, and whirlpool center is hollow, easily causes the reduction of pump housing water absorption, does not reach to use and wants
Ask, centrifugal pump abnormal wear is also resulted in when serious；Anti- whirlpool centrifugal pump inhalation part of the present utility model, is being originally defined whirlpool
The position at whirlpool center, there is provided center flow channels, from inlet bottom liquid make-up to center hollow position, change centrifugal pump suction
The fluid flow pattern of mouth, so as to ensure the soakage of the pump housing, improves the operation stability of the pump housing.
2nd, centrifugal pump can produce larger centrifugal force at work, and solid impurity constantly rushes under the action of the centrifugal force in water
Filter mantle is hit, because common filter mantle is mostly one layer of thin wire netting, long-term use is easily by impurity blastic deformation；In order to carry
Exceed the intensity of filter bowl, the present apparatus has added vertical reinforced bar part in the inside circumference of filter mantle, be effectively improved screen pack by
Power situation, its deformation is avoided, improve the service life of filter mantle.
3rd, in use, top water velocity is because close to impeller, centrifugal force is bigger, water velocity faster, due to
There is provided center flow channels, such case is also presented in the current of supplement in the middle part of runner, in order to ensure the steady of top centrifugal pump water absorption
Qualitative, center flow channels are designed to up-small and down-big horn-like by the present apparatus, although top flow velocity is accelerated, outlet reduces, and enters
Fluid flow it is also just corresponding reduce, so as to ensure the relatively stable of flow.
