Abstract
The invention discloses a broadband gas-liquid two-phase spring pulsation damper which comprises parts including an inlet end communication body, a sealing ring, a buffer cap, a body, a rubber spring or corrugated pipe spring, a flow passing net barrel, an outlet end communication body and the like. According to pulsatile fluid flowing through the inlet end of the broadband gas-liquid two-phase spring pulsation damper, fluid peak value kinetic energy is transmitted to the rubber spring or corrugated pipe spring in the body through end flanges of the buffer cap and the flow passing net barrel, and the rubber spring or corrugated pipe spring generates elastic deformation to absorb pulsation kinetic energy; and when a fluid peak value comes, the rubber spring or corrugated pipe spring releases stored energy and recover deformation. Through circulated reciprocation of the above process, fluid pressure pulsation is restrained. The broadband gas-liquid two-phase spring pulsation damper is suitable for fluid pulsation eliminating of liquid flow and gas flow within the 0-80Hz pulsation frequency range. The broadband gas-liquid two-phase spring pulsation damper has the obvious effects of being simple in device structure, small in size, light and high in bearing pressure compared with a traditional damper, and the pulsation eliminating rate is 95% or above.
Description
Technical field
The invention belongs to hydraulic pressure and pneumatic fluid technique field, are related to a kind of including gas, liquid and gas-liquid two-phase fluid
Wideband gas-liquid two-phase spring ripple damper.
Background technology
Including work packages such as piston, plunger, barrier film, gear or blades in the pump housing reciprocating or gyration stream
Body conveying device, be all alternately sucked by making single or several working chambers volume in the pump housing periodically change and
Fluid is discharged, the change of volume can cause the pulsation of institute's trandfer fluid.Displacement type conveying equipment fluid produced when working
Pulsation, can not only make fluid produce the mass flow discrepancy weighing apparatus of moment, while can also cause the vibrations and abrasion of conveyance conduit, and then produce
The failure damage of raw pipeline and pipe connection portion.To solve this problem, the technical field also has some diaphragm type surge tank, flexible pipes
The device such as buffer and piston-type buffer is applied in engineering practice, but because barrier film and flexible pipe are difficult to bear high frequency
Secondary flexural deformation, causes that service life is short, replacement cost is high and is difficult to bear the defects such as high pressure；Especially above-mentioned diaphragm type delays
The devices such as tank, flexible pipe buffer and piston-type buffer are rushed due to being all the deformation Absorbing Fluctuation energy by filling compressible gas
Amount, is only applicable to application of the ripple frequency less than 7Hz, because if frequency is too high, diaphragm, air bag or piston have little time response,
The effect for eliminating pulsation is not had.
The content of the invention
The technical problem to be solved in the present invention is the deficiency for overcoming above-mentioned various conventional buffer devices, there is provided a kind of structure letter
List, small volume, lightweight and to bear pressure high, is applicable to the wideband gas-liquid two-phase spring damping of pulsation of various more extensive frequency systems
Device.
In order to solve above technical problem, the invention provides a kind of wideband gas-liquid two-phase spring pulsation resistance of following structure
Buddhist nun's device, including entrance point connected component, sealing ring, buffer cap, body, rubber spring or bellows springs, drift net cylinder and outlet excessively
The parts such as end connected component are constituted.
Body of the present invention is the closure cylinder that can bear Fluid pressure；
The buffer cap is the semiclosed cylinder of hat shape with deflection cone, and the water conservancy diversion conical surface is provided with spiral stream guidance groove, buffer cap
Bottom is provided with multiple flowing holes；The buffer cap is made up of the material with certain rigidity and abrasion-resistance.
It is described cross drift net cylinder be to pass through can fluid, and be provided with tube wall multiple apertures with hem flange
Tubular barrel.The drift net cylinder of crossing can have certain rigid and erosion resistant material for metal, macromolecule silk screen or ceramics etc.
Material is made.
The rubber spring is to be filled between body and mistake drift net cylinder the element for attracting deposit and discharging fluid pulsation kinetic energy；Institute
State the rubber element that rubber spring is high resiliency deformation recovery capability, be compressed axially be radially expanded it is axially swollen with radial compression
Swollen ability.
The bellows springs are to be filled between body and mistake drift net cylinder the element for attracting deposit and discharging fluid pulsation kinetic energy；
The bellows springs are radially expanded and radial compression axial expansion by making with elastomeric material with being compressed axially
Ability.
The entrance point connected component of the body left end is connected with the outlet of fluid conveying machine, the port of export of body right-hand member
Connected component is connected with transfer pipeline.In view of the diversity of connected mode, pipeline connecting device is including but not limited to of the invention attached
Type of attachment shown in figure.
Particularly, the principle and structure of wideband gas-liquid two-phase spring ripple damper of the present invention can also be integrated in stream
Within body conveying machinery device, as fluid conveying machine device the functional module of fluid pulsation is stabilized.
The remarkable result of the present invention is achieved by the following technical solution：Flow through entrance point connected component with pulsation peak
The high-pressure fluid of the energy of flow, acts on first the end flanges for then passing through drift net cylinder on the conical surface of buffer cap again the kinetic energy
Rubber spring or bellows springs are passed to, is run through absorbing the kinetic energy and elastic deformation occurring；By buffer cap periphery mistake
Discharge orifice and entered the liquid stream with the peak energy of flow of drift net cylinder, further passed through the aperture compression rubber spring on drift net cylinder
Or bellows springs, it is run through absorbing the kinetic energy and elastic deformation occurring.
After pulsation peak stream passes through, rubber spring or bellows springs recover its deformation and the energy for being absorbed are released to
Pulsation paddy stream.It is this to attract deposit the pulsation peak energy of flow and release stored energy to paddy stream of pulsing by rubber spring or bellows springs
Process so that the peak valley pressure of pulsing gluid is balanced, and serves the beneficial effect for stabilizing fluid pulsation.
Because rubber spring or bellows springs have the effect of energy of attracting deposit more by force so as to can be attracted deposit with less deformation
The fluid pulsation kinetic energy of high peaks, thus its volume can be caused to become very little；Because its deformation is less, response is very fast, because
And the fluid pulsation for being applicable to broad ripple frequency scope is stabilized and is eliminated.
Wideband gas-liquid two-phase spring ripple damper of the present invention is applied to ripple frequency scope between 0～40Hz
The pulsation of liquid stream and air-flow two-phase fluid is eliminated.
The remarkable result of the present invention is, not only more traditional diaphragm type surge tank, flexible pipe buffer and piston-type buffer
Deng apparatus structure is simple, small volume, lightweight and to bear pressure high, and suitable for broad ripple frequency model between 0～80Hz
The fluid delivery application enclosed, so that pulsation elimination factor is up to more than 95%.
