Description
Technical field
The utility model belongs to pump valve associated mechanical technical field, and in particular to a kind of self-priming for being used to start centrifugal pump
Tank.
Background technology
In Chemical Manufacture, centrifugal pump is most-often used liquid conveying machinery, because centrifugal pump does not have suction capacity, is made
With preceding, in order to avoid occurring air sinuses phenomenon, it is necessary to fill pump with liquid, until having liquid in the on-state at pump case top vent
Untill body is emerged, the effect of suction line bottom valve is exactly to prevent that pour into liquid before starting flows out out of pump in centrifugal pump device,
But, the strong liquid for being corrosive not only irrigates liquid into pump and is inconvenient, and one-way bottom valve is also often corroded
It is bad, easily occur bottom drain phenomenon, therefore one-way bottom valve is replaced with self-sucking pot now, taken out by liquid in self-sucking pot after turn on pump
Go out, pressure reduction after make the pressure overflow in storage tank tank into self-sucking pot, by constantly thering is liquid to be inhaled into, can continue for from
Heart pump is pumped, but in actual use, the liquid in fluid reservoir has solid particle or impurity, be transported to centrifugal pump or other
During equipment, certain influence is likely to result in, meanwhile, there may be the solia particle easily precipitated in transmission medium, in self-sucking pot
Portion's precipitation may influence the use of self-sucking pot, while can not also ensure transmission medium is made transmission, it is therefore desirable to these
Problem is further studied.
Utility model content
The purpose of this utility model is that there is provided a kind of self-sucking pot for being used to start centrifugal pump for existing issue.
The utility model is achieved through the following technical solutions：A kind of self-sucking pot for being used to start centrifugal pump, including from
Cucurbitula tank body, tank wall, which is provided with outside vertical bar shape inlet, inlet, installs reverse V-shaped pipette, and the pipette other end is located at storage
Liquid bath bottom, is provided with screen pack in the pipette of reservoir, and pipette be connected with inlet one section is shape tube, abnormal shape
Pipe is the vertical bar shaped matched with inlet by cylindrical shape transition, and shape tube is connected with inlet with the horizontal tangent direction at this
Connect, liquid feeding mouth is provided with the top of tank body, tank body upper end side wall is provided with gas vent, and tank body is close to reservoir lower end position provided with maintenance
Tap hole, with the relative opposite side of maintenance tap hole provided with pumping hole is connect, connects pumping hole and connect with centrifugal pump, centrifugal pump connect motor and
Export water pipe.
As further improvement of these options, the screen pack is metal-rubber screen pack, can be by bulky grain thing
Matter is filtered.
As further improvement of these options, the special-shaped tube portion of the reverse V-shaped pipette is tilted down and feed liquor
Mouth connection.
As further improvement of these options, pressure-detecting device is provided with tank body, centrifugal pump is operationally protected
Hold tank body internal pressure power and be maintained at 0.6MPa or so.
As further improvement of these options, the inlet is located at the upside of tank body horizontal center line.
The utility model has advantages below compared with prior art：The pipette is inverted V-shape, located at the water of tank wall
Flat tangential direction, can make liquid of the liquid of suction along sidewall impact tank interior, the effect of agitation liquid be reached, so that liquid
In vivo evengranular is distributed in liquid medium, will not be blocked centrifugal pump, be made the transmission of its safety and stability containing the liquid of particle
Body medium；Utilize pressure, appropriate regulation, it is ensured that the transmission of centrifugal pump safety and stability is situated between in pressure-detecting device detection self-sucking pot
Matter, reverse V-shaped pipette sets screen pack close to the part of reservoir, can directly filter out the bulky grain thing for being not required to transmission, have
Effect avoids the abrasion that impurity particle is caused to device.
