Abstract
The utility model relates to a vertical self-sucking pump which is composed of a bearing, a mechanical seal, a rotation shaft, a water inlet seat, a water storage chamber, an extrusion chamber, an impeller and a guiding blade, and realizes movable sealing on shaft outlet gap positions by means of the factor that the impeller and the guiding blade are arranged in a liquid storage chamber of a pump body through arranging the impeller and the guiding blade at the front end of the rotation shaft, the bearing and the mechanical seal are arranged on the rear portion of the rotation shaft, the water inlet seat is arranged on the middle portion of the rotation shaft, the water inlet seat and a water inlet are communicated, a gas return hole is arranged on the inner wall of the water inlet seat, which is separated from the water storage chamber. The vertical self-sucking pump has simple structure and simple installation and use.
Description
Technical field:
The utility model relates to a kind of vertical self-sucking pump, belongs to the self-priming pump that chemical field uses.
Background technique:
At chemical field, filler or mechanical seal that the structural type of existing common vertical self-sucking pump normally adopts sub-propeller to replace Vintage Product to adopt; Pump when work sub-propeller and main impeller rotate together, the pressure that utilizes its work effect to use a gap location is reduced to and is less than or equal to atmospheric pressure, thereby reaches the effect of motive sealing; Pump is realized the function of a lifelong self-priming of drainage, be rely on the water outlet check valve effectively close with suction line on effective open and close of air valve liquid storage when realizing that pump is shut down and the self-priming during start.Because pump in the running, sub-propeller and main impeller rotate together, thereby will inevitably consume certain available power, and the power of this additive decrementation can not convert effective liquid energy to, so, will cause total work decrease in efficiency of self-priming pump, produce high energy consumption.In addition; because when shutting down, closing of check valve of outlet must have certain lag time, thereby has the problem that liquid leaks via the shaft gap location in the pump when shutting down all the time; the environmental condition that this just has influence on the pump work place that is to say and can pollute environment.In addition, She Ji pump also must configuration use solenoid valve like this, and from present use condition, solenoid valve work problem unreliable and that the life-span is short badly influences the working life of pump.This has also increased the operation cost of enterprise virtually.
Summary of the invention:
In order to overcome the existing defective of Vintage Product, the purpose of this utility model will provide a kind of vertical self-sucking pump exactly; The purpose of this utility model is to realize like this, vertical self-sucking pump, formed by bearing, mechanical seal, rotating shaft, influent base, water chamber, delivery chamber, impeller, stator, it is characterized in that: the front end of rotating shaft is provided with impeller and stator, described impeller and stator are set in the liquid storage room of the pump housing,, be provided with bearing and mechanical seal at the rear portion of rotating shaft, the middle part of rotating shaft is provided with influent base, and described influent base communicates with water intake; On the inwall that influent base and water chamber are separated by, have a return-air hole.The utility model is simple in structure, and is easy to operate, and cost of production is low, do not need user's later stage operation cost.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
In the drawings, vertical self-sucking pump, formed by bearing, mechanical seal, rotating shaft, influent base, water chamber, delivery chamber, impeller, stator, it is characterized in that: the front end of rotating shaft is provided with impeller and stator, described impeller and stator are set in the liquid storage room of the pump housing, be provided with bearing and mechanical seal at the rear portion of rotating shaft, the middle part of rotating shaft is provided with influent base, and described influent base communicates with water intake; On the inwall that influent base and water chamber are separated by, have a return-air hole.During concrete enforcement, liquid under the effect of impeller, is drawn into liquid storage room in liquid entering hole enters into intake chamber, along with the high speed rotating of impeller, outside the excavationg pump, during the utility model pump work, rely on its structure characteristic, realized initiatively protection, cancelled the sub-propeller of making idle work.Because the gap location of shaft is installed in suction chamber, thereby pump because impeller sucks liquid, causes the liquid in the influent base to flow to impeller when work, and make the fluid pressure in the influent base be lower than the outside atmospheric pressure of shaft gap location, thereby realize the motive sealing of shaft gap location.Adopt mechanical seal, when pump shutdown, be used to stop liquid in the influent base under the fluid pressure of rising pipe via the shaft gap location to external leakage.When pump starts, be used for stoping outside air to suck via the shaft gap location, shorten the starting time.The utility model has a return-air hole on the inwall that influent base and water chamber are separated by, cancelled short air valve of functional reliability difference and life-span, thereby made the work of novel vertical self-priming pump more reliable, and cost of production and operation cost are lower.
