Background technology
Jet vacuum pump is to utilize machinery, physics, chemistry or the method for materialization, generates, improves and ties up within the enclosed space
Hold the device of vacuum.Generally be made of immersible pump, jet vacuum pump, pump box three parts, be widely used in oil, chemical industry, food,
Among the techniques such as reduction vaporization, crystallization, distillation, drying, decoloration, deodorization, the vacuum handling of the industries such as pharmacy, light industry, environmental protection.
Immersible pump generally comprises the pump housing, motor, impeller, and water inlet, water outlet are provided on the pump housing；Electric motor starting band movable vane
Wheel rotation, drives water to enter from water inlet, is then discharged from water outlet, water stream channel is the hollow space shape by pump body
At channel.
Immersible pump is the machinery for conveying liquid or liquid being made to be pressurized.It passes the mechanical energy of prime mover or other external energies
Liquid is given, liquid energy is made to increase, is mainly used to convey liquid to include water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid
Metal etc. also can transport liquid, admixture of gas and the liquid containing suspended solids.
User's water consumption is usually dynamic, therefore insufficient water or the superfluous situation that supplies water happen occasionally.And with water and
Uneven concentrated reflection between water supply is in the pressure of water supply, i.e., few with supplying water water, then pressure is low more；It is few with water and supply water
More, then pressure is big.The constant in a certain range of pressure of supply water is kept, water supply can be made and is balanced with holding between water, to carry
The high quality to supply water.
Invention content
The technical problem to be solved by the present invention is in view of the shortcomings of the prior art, propose a kind of jet stream liquid keeping ejector
The adjustable discharge pressure jet vacuum pump constant in a certain range of pressure of supply water at body input end.
The technical solution that the present invention proposes to solve above-mentioned technical problem is：A kind of adjustable discharge pressure jet vacuum pump,
Including immersible pump, ejector and vacuum tank, the immersible pump includes the pump housing, motor and impeller in the pump housing, the pump housing
On be provided with inlet and outlet, the motor output shaft is stretched out and is connected with impeller middle spindle downward, the ejector
Injection liquid input end is connected to the water outlet of the immersible pump, and the inlet port connection vacuum tank outlet of the ejector is described
The water outlet of immersible pump, which is equipped with, to be discharged the adjustable plate in direction perpendicular to flow and is parallel to flow water outlet direction and is set to water outlet
Fixing axle at mouth center, is formed with water inlet, the adjustable plate includes outer ring between the adjustable plate and water outlet
Annular slab and the interior plectane in outer ring annular slab, the interior plectane are fixed in fixing axle, the outer ring annular slab and interior
Torsional spring is equipped between plectane.
The present invention is using the advantageous effect of above-mentioned technical proposal：It is equipped with by the water outlet in the immersible pump pump housing vertical
It is discharged the adjustable plate in direction in flow and is parallel to flow water outlet direction and the fixing axle at water outlet center, works as water outlet
Locate water flow it is little when, flow is flowed out by water inlet, and when water outlet water flow is big, flow is by outer ring annular slab
It opens and tilts, increased water flow flow maintains the perseverance in a certain range of pressure of supply water at the injection liquid input end of ejector
It is fixed.
The improvement of above-mentioned technical proposal is：The area ratio of the water inlet, outer ring annular slab and interior plectane is
1:1:1。
The improvement of above-mentioned technical proposal is：The ingredient and mass percentage content that the 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%, remaining is Fe and is inevitably mingled with
Element.
Antimony:630 DEG C of Sb fusing points, it is to promote pearlite formation element that can make the complete pearlite of tissue to thin-section casting
Change, and atomic to different wall thickness matrix difference, sectional sensitivity significantly reduces.With the larger latent heat of fusion, it is added 0.04
The Sb of~0.08% content, hence it is evident that refinement macrostructure, microcell forms temperature fluctuation in part, causes indigenous graphite core, can be thin
Graphite.
The present invention is using the advantageous effect of above-mentioned technical proposal：By be added in outer ring annular slab micro Sb and
Cu, low production cost, wear-resisting property are good so that the service life that adjustable discharge pressure jet vacuum pump works in water improves bright
It is aobvious.
