Description
Technical field
The utility model relates to water pump technologies, more particularly, to a kind of chemical industry self priming pump.
Background technique
Chemical industry occupies an important position in the national economy of various countries, is that the basic industry of many countries and pillar produce
Industry, comprising the departments such as chemical industry, oil refining, metallurgy, the energy, light industry, petrochemical industry, environment, medicine, environmental protection and military project be engaged in engineering design,
Finely with the industry of daily-use chemical industry, the energy and power, technological development, productive technology management and scientific research etc..Chemical work
The development speed and scale of industry directly affect each department of social economy, and world's chemical products annual value of production has been more than
1500000000000 dollars.Since chemical industry is of a great variety, complex process, product multiplicity, the pollutant kind discharged in production is more,
Quantity is big, toxicity is high, and therefore, chemical industry is heavy polluter.Meanwhile chemical products are at processing, storage, use and waste
The links such as reason are likely to generate a large amount of noxious materials and influence ecological environment, jeopardize human health.Development of chemical industry
Sustainable development path is walked to have important practical significance for human economy, social development.
Chemical industry self priming pump refers to the vane pump for being used in chemical field, and compared with other kinds of pump, it has construction letter
It is single, not easy to wear, run smoothly, noise is small, water outlet is uniform, it is easy to adjust, high-efficient, have corrosion resistant, wear-resisting, high temperature resistant etc. it is excellent
Point；It can be used for storing the container of liquid lower than ground level 1-4 meters, inconvenience is flowed backward and the occasion of liquid feeding；It is fixed on ground using the pump
It can continuously or discontinuously be extracted on plane post, convey all kinds of chemical mediums, currently, chemical industry self-priming pump configuration in the prior art is deposited
Vapor-liquid separation in defect, pump chamber is poor, and liquid kinetic energy rejection is larger, and self-priming performance is lower.
Utility model content
Purpose of utility model: it in order to overcome the shortcomings of background technique, is mentioned the utility model discloses a kind of using partition
The vapor-liquid separation ability in self-priming pump chamber is risen, liquid in rotation kinetic energy is eliminated, increases kinetic energy and is converted to pressure energy, so as to improve self priming pump
The chemical industry self priming pump of suction, self-priming time and whole efficiency.
Technical solution: chemical industry self priming pump described in the utility model, including the pump housing, the pump housing is interior to be arranged intake antrum, leaf
Chamber, water chamber are taken turns, the intake antrum is connected to by impeller cavity with water chamber, and water inlet, the water outlet are arranged on the intake antrum
Water outlet is set on chamber, the connectivity part of setting impeller face intake antrum and impeller cavity in the impeller cavity, inside the water chamber
Side positioned at impeller water outlet is obliquely installed partition.
Chemical liquid enters from the inlet intake antrum, enters back into impeller cavity and gets rid of through impeller to water chamber, finally by water outlet
Discharge, is arranged partition in water chamber, and the self priming pump can be made to be promoted in startup stage steam-water separation speed, and self-priming performance improves；
In operational process, the water that partition can prevent impeller from throwing away generates whirlpool in water chamber, reduces volumetric loss, efficiency of imbibition
It improves.
Further, the two side ends of the partition are fixed with the pump housing respectively, and the partition extends axis by being located at water chamber
On outer end toward impeller direction extend, and towards the water outlet side of impeller tilt, so that liquid is had just enter into water chamber i.e. by partition
Effect.
Further, the outer end of the partition is more than or equal to 10mm at a distance from water chamber outer end.
Further, the inclined angle in water outlet side of the partition towards impeller is 20 ° -30 °.
Further, the partition and the pump housing are integrally formed.
Further, it is gap-matched between the impeller and the pump housing, gap 0.2mm-0.5mm, self priming pump performance
As gap increases and rapid decrease.
Further, the horizontal position of the water inlet is higher than the entrance location of impeller, is not only able to achieve self-priming, but also be able to achieve
Increase the effect of suction.
The utility model has the advantages that compared with prior art, the advantages of the utility model are as follows: this chemical industry self priming pump passes through in water chamber
Reasonable diaphragm structure is set, so that self priming pump is promoted in self-priming startup stage steam-water separation speed, self-priming performance improves；Operation
Partition eliminates the Maelstrom in pump chamber in the process, reduces volumetric loss, and the self-priming efficiency of pump increases, and reaches energy saving high
Effect.
