Description
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 utilizing machinery, physics, chemistry or materialization, produces, improves and maintain the device of vacuum within the enclosed space.Generally it is made up of immersible pump, jet vacuum pump, pump box three part, is widely used among the techniques such as the reduction vaporization of the industries such as oil, chemical industry, food, pharmacy, light industry, environmental protection, crystallization, distillation, dry, decolouring, deodorize, vacuum handling.
Immersible pump generally comprises the pump housing, motor, impeller, and the pump housing is provided with water inlet, outlet；Electric motor starting impeller rotates, and drives water to enter from water inlet, then discharges from outlet, and water stream channel is the passage formed by the hollow space of pump body.
Immersible pump is conveying liquid or the machinery making fluid pressurization.It sends mechanical energy or other external energies of prime mover to liquid, liquid energy is made to increase, it is mainly used to carry liquid to include water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc., it is possible to conveying liquid, admixture of gas and the liquid containing suspended solids.
User's water consumption is usually dynamically, and therefore insufficient water or the superfluous situation that supplies water happen occasionally.And with water and the uneven concentrated reflection between supplying water on the pressure supplied water, namely many and supply water few with water, then pressure is low；With water is few, water supply is many, then pressure is big.Keeping the constant within the specific limits of pressure of supply water, water supply can being made and with keeping balance between water, thus improve the quality of water supply.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, it is proposed to the adjustable jet vacuum pump of discharge pressure constant within the specific limits of a kind of injection liquid entrance point place pressure of supply water keeping ejector.
nullThe present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of adjustable jet vacuum pump of discharge pressure，Including immersible pump、Ejector and vacuum tank，Described immersible pump includes the pump housing、It is located at the motor in the pump housing and impeller，The described pump housing is provided with water inlet and outlet，Described motor output shaft stretches out down and is connected with impeller middle spindle，The injection liquid entrance point of described ejector connects the outlet of described immersible pump，The inlet port connection vacuum tank outlet of described ejector，The water outlet of described immersible pump is provided with the adjustable plate being perpendicular to current water outlet direction and is parallel to current water outlet direction and is located at the fixing axle of outlet center，Current flow channels it is formed with between described adjustable plate and water inlet，Described adjustable plate includes outer ring annular slab and the interior plectane being located in the annular slab of outer ring，Described interior plectane is fixed on fixing axle，It is provided with torsion spring between described outer ring annular slab and interior plectane.
The present invention adopts technique scheme to provide the benefit that: by being provided with, at the water outlet of the immersible pump pump housing, the adjustable plate being perpendicular to current water outlet direction and being parallel to current water outlet direction and be located at the fixing axle of outlet center, when water outlet discharge is little, current are flowed out by current flow channels, when water outlet discharge is big, outer ring annular slab is opened inclination by current, increased water flow flow, maintains injection liquid entrance point place pressure of supply water constant within the specific limits of ejector.
The improvement of technique scheme is: the area ratio 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 be: C:3.5～3.7%, 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: Sb fusing point 630 DEG C, it is to promote pearlite forming element, to thin-section casting, can make the complete pearlite of tissue, and different wall matrix difference is atomic, and sectional sensitivity significantly reduces.There is the bigger latent heat of fusion, add the Sb of 0.04～0.08% content, hence it is evident that refinement macrostructure, rise and fall in part microcell formation temperature, cause indigenous graphite core, graphite can be refined.
The present invention adopts technique scheme to provide the benefit that: by enclosing Sb and the Cu adding trace in annular slab outside, low production cost, and anti-wear performance is good so that discharge pressure is adjustable, and jet vacuum pump works in water is obviously improved service life.
