Description

Discharge pressure is adjustable jet vacuum pump
Technical field
The present invention relates to a kind of immersible pump, belong to Radial Flow non-positive-displacement fluid pump technical field.
Background technology
Jet vacuum pump is the method for utilizing machinery, physics, chemistry or materialization, produces, improves and maintain the device of vacuum in enclosure space. Generally formed by immersible pump, jet vacuum pump, pump box three parts, be widely used among the techniques such as the reduction vaporization, crystallization, distillation of the industries such as oil, chemical industry, food, pharmacy, light industry, environmental protection, dry, decolouring, deodorization, vacuum handling.
Immersible pump comprises the pump housing, motor, impeller conventionally, is provided with water inlet, delivery port on the pump housing; Electric motor starting impeller is rotated, and drives water to enter from water inlet, then discharges from delivery port, and water stream channel is the passage forming by the hollow space of pump body.
Immersible pump is the machinery of carrying liquid or making liquid supercharging. It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc., also can carry liquid, admixture of gas and the liquid containing suspended solids.
User's water consumption is generally dynamic, and therefore insufficient water or the superfluous situation that supplies water happen occasionally. And the concentrated reflection of imbalance between water and water supply is on the pressure supplying water, water is many and supply water less, and pressure is low; Water few and supply water many, pressure is large. Keep the constant within the specific limits of pressure of supply water, can make to keep balance between water supply and water, thereby improved the quality supplying water.
Summary of the invention
The technical problem to be solved in the present invention is, for prior art deficiency, proposes a kind of constant adjustable jet vacuum pump of discharge pressure within the specific limits of the jet liquid-inlet end place pressure of supply water that keeps ejector.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of discharge pressure is adjustable jet vacuum pump, comprise immersible pump, ejector and vacuum tank, described immersible pump comprises the pump housing, be located at motor and impeller in the pump housing, on the described pump housing, be provided with water inlet and delivery port, described motor output shaft stretches out down and is connected with impeller middle spindle, the jet liquid-inlet end of described ejector is communicated with the delivery port of described immersible pump, the air inlet end of described ejector is communicated with vacuum tank outlet, the water outlet of described immersible pump is provided with perpendicular to the adjustable plate of current water outlet direction and is parallel to current water outlet direction and is located at the fixed axis of delivery port center, between described adjustable plate and water inlet, be formed with current flow channels, described adjustable plate comprises outer ring annular slab and is located at the interior plectane in the annular slab of outer ring, described interior plectane is fixed on fixed axis, between described outer ring annular slab and interior plectane, be provided with torsion spring.
The present invention adopts the beneficial effect of technique scheme to be: by being provided with perpendicular to the adjustable plate of current water outlet direction at the water outlet of the immersible pump pump housing and being parallel to current water outlet direction and being located at the fixed axis of delivery port center, in the time that water outlet discharge is little, current flow out by current flow channels, in the time that water outlet discharge is large, outer ring annular slab is opened inclination by current, increased water flow flow, has kept jet liquid-inlet end place pressure of supply water constant within the specific limits of ejector.
The improvement of technique scheme is: the ratio of the area of described current flow channels, outer ring annular slab and interior plectane is 1:1:1.
The improvement of technique scheme is: composition and mass percentage content that described outer ring annular slab contains are: C:3.5～3.7%, and Sb:0.04～0.08%, Mn:0.40～0.60%, Cu:0.30～0.40%, all the other are Fe and inevitable tramp element.
Antimony: 630 DEG C of Sb fusing points, it is to promote pearlite forming element, to thin-section casting, can make to organize complete pearlite, and atomic to different wall matrix difference, sectional sensitivity obviously reduces. Have the larger latent heat of fusion, add the Sb of 0.04～0.08% content, obviously refinement macrostructure, rises and falls in part microcell formation temperature, causes indigenous graphite core, can refinement graphite.
The present invention adopts the beneficial effect of technique scheme to be: add micro-Sb and Cu by enclosing outside in annular slab, and low production cost, anti-wear performance is good, the adjustable jet vacuum pump of discharge pressure is worked in water and improve obviously service life.
