Description
Technical field
The utility model belongs to the technical field of non-varactor pump, and in particular to a kind of with the vertical of automatic liquid-drainage function
Submerged pump.
Background technique
Centrifugal pump is the pump for carrying out trandfer fluid by the centrifugal force generated when impeller rotation, and fluid is inhaled into from water inlet, from
Water outlet is pumped out.When work, pump shaft drives the impeller high speed rotation in pump case, and under the action of the centrifugal force, fluid is in pump case
Impeller circumferential direction water dumping corresponding with impeller is thrown toward impeller outer edge in space, being connected to impeller circumferential direction water dumping space through pump case
Scroll casing type discharge runner is pumped out from water outlet, at impeller center, then negative pressuren zone, extraneous fluid is formed after being thrown out of because of fluid
Be inhaled under pressure from water inlet, impeller do not stall it is dynamic so that fluid under the action of impeller constantly sucking and spue,
Achieve the purpose that trandfer fluid.
The principle of vertical submerged pump is identical as above-mentioned principle, referring to the existing vertical submerged pump of attached drawing 3, only its pump shaft 1
It is in vertical direction, its entire pump case 2 need to be placed in the liquid of pumping when work, and in overhaul or other be needed pump case 2
When the case where taking out from liquid, the pump after taking-up usually has a large amount of corresponding liquid, is not clean, and gives subsequent dismantling maintenance dimension
It the work such as repairs and causes difficulty, it is number especially when pumping liquid and being toxic, easy crystallization and freezing or have the fluid media (medium) of irradiation
It is tired, or even the body of operator is damaged.In fact, according to the principle that Water seeks its own level, as long as by vertical after taking-up
Submerged pump is tilted repeatedly from multi-angle, is rocked, so that it may so that the remaining liquid discharge that pump is taken out of, but operator is often because of fiber crops
It is tired of or has directly been ignored as the operation, just feels to chase after after causing dismantling maintenance and repair operational difficulties even to cause physical impairment
It is too late to repent, thus, it is necessary to which vertical submerged pump of the band from draining function is arranged.
Summary of the invention
For the above-mentioned deficiency of the prior art, the technical problem to be solved by the present invention is to provide one kind with automatic row
The vertical submerged pump of liquid function avoids the pump case of vertical submerged pump after taking out in liquid, is not easy to arrange with a large amount of remaining liquid waters
Difficult problem is brought to follow-up work out, extraction raffinate can be automatically drained out without exclusively carrying out drain operation by obtaining, and be guaranteed subsequent
Work effect that is smooth and ensureing operator's personal safety.
In order to solve the above technical problems, the utility model adopts the following technical solution:
Vertical submerged pump with automatic liquid-drainage function, including pump case and vertical pump shaft, the pump case includes detaining up and down
The pump cover and the pump housing of conjunction；The upper end of the pump shaft connects motor, and lower end passes through the pump cover and connect with the impeller in pump case

Liquid has been easiest in pump case to remain and be not easy directly to be found, vertical submerged pump of the invention, when
When being proposed from pumping liquid (usually straight up propose), the liquid remained in pump case under the effect of gravity, from water inlet
Automatic all discharges, exclusively carry out drain operation without operator, avoid the artificial omission of operational sequence；Stream is remained in pump case
Matter is all discharged automatically, will not cause difficulty to work such as subsequent dismantling maintenance and repairs, it is toxic, easy for also avoiding pumping liquid
Crystallization and freezing or the physical impairment caused by operator when having the fluid media (medium) of irradiation, ensure that the smooth of follow-up work
It carries out, guaranteeing role is also functioned to operator's personal safety.
Above-mentioned technical proposal is further improved, the upper surface of the pump cover is to put around centered on position by pump shaft
Inclined surface made of slope is to avoid ponding on pump cover.
In this way, being automatically drained out outer in addition to remaining liquid in pump case, while also avoiding in the remaining liquid in the top of pump case, when from
When proposing in pumping liquid, the surrounding of the liquid automatic stream pump cover outside pump case not will form remaining.
Further, on the pump cover for pump shaft across hole inner wall and rotor corresponding in hole have gap.
There is liquid to remain in the hole of pump cover in this way, further avoiding the pump shaft for being not easy to be noticed, liquid is in gravity
It flows in impeller circumferential direction water dumping space under effect from the gap, then is automatically drained out from water inlet.
Further, the pump cover is equipped with electric machine support and connects the motor by the electric machine support, described
Electric machine support encloses the cell structure for setting a circle for the circumferential direction in pump shaft to avoid ponding；Interconnecting piece has been installed in the electric machine support
And it is connect by the interconnecting piece and bearing with pump shaft to increase pump shaft rotational stability.
In this way, can avoid having liquid remaining in the electric machine support in part in closed tube shape, consider comprehensive；In electric machine support
It has installed interconnecting piece and has been connect by the interconnecting piece and bearing with pump shaft, stability when pump shaft rotation can be increased, reduce pump
Vibration in the course of work, though on pump cover for pump shaft across hole inner wall and rotor corresponding in hole be arranged between
Gap will not influence the stability of pump work without connecting bearing.
Further, offer water outlet on the pump case, the water outlet by discharge runner in pump case with it is described
The connection of impeller circumferential direction water dumping space, the lower surface of the discharge runner is the inclination for gradually decreasing or gradually rising along water (flow) direction
Face is to avoid discharge runner internal water accumulation.
Possible remaining liquid in discharge runner is considered in this way, taking into account, avoids having in discharge runner liquid remaining, when from pump
It send when being proposed in liquid, if the lower surface of discharge runner is along the inclined surface that water (flow) direction gradually decreases, remaining liquid exists
Be discharged under gravity from water outlet, if the lower surface of discharge runner be along the inclined surface that water (flow) direction gradually rises,
Remaining liquid is flowed in impeller circumferential direction water dumping space under the effect of gravity, then is automatically drained out from water inlet.
Compared with prior art, the utility model has the following beneficial effects:
The vertical submerged pump of the utility model is from inhalation flow, pump case inner space, discharge runner, pump case shape and electricity
The various aspects such as machine support have fully considered the automatic exclusion of remaining liquid, have matched corresponding structural form, guarantee from pump flow
When proposing in matter, liquid is remained under the effect of gravity, it is all automatic to exclude；Without exclusively carrying out drain operation, operative employee is avoided
The artificial omission of sequence；
Remaining liquid is all automatic to be excluded, and will not be caused difficulty to work such as subsequent dismantling maintenance and repairs, be also avoided pumping
The physical impairment caused by operator when liquid being sent to be toxic, easy crystallization and freezing or have the fluid media (medium) of irradiation, guarantees
The smooth progress of follow-up work, has ensured the personal safety of personnel, has eliminated security risk.
