Description
Technical field
The embodiment of theme disclosed herein relates generally to the facility of the reciprocating compressor used in gas industries, and more
In particular to constructively using pressure fluctuation improving the volumetric efficiency of compressor, i.e. realize pulse pressure-charging effect.
Background technology
The compressor used in gas industries must is fulfilled for industry specific requirement, and this considers such as compressed gas usually has
Corrosivity and flammable.American Petroleum Institute (the API) (machine of the industry standard to generally acknowledging for the equipment setting in gas industries
Structure) issued file API618, which lists the complete a set of minimum requirements with regard to reciprocating compressor.
Compressor can be categorized into positive displacement compressor (for example, reciprocating compressor, screw compressor or stator compression
Machine) and dynamic compressors (for example, centrifugal compressor or axial compressor).In positive displacement compressor, by retaining gas, and
And and then reduce wherein retain gas volume come realize compression.In dynamic compressors, by the pre- of the inside of compressor
(for example, rotate element) kinetic energy is converted into pressure energy to realize compression at first defined location.
Preferably compression circulation (illustrating by way of the development of tracking pressure-volume is with curve chart in FIG) includes
At least four stages：Expansion, suction, compression and discharge.When compression fluid is discharged from discharge chambe when loop ends are compressed,
In discharge pressureP 1 A small amount of fluid remain trapped in and empty volumeV 1 In (that is, the minimum volume of discharge chambe).Follow in compression
During the expansion stage 1 of ring and sucting stage 2, piston movement, to increase the volume of discharge chambe.It is when starting the expansion stage 1, defeated
Valve is sent to close (inlet valve is remained turned-off), and and then, the reduced pressure of fluid is retained, because can be used for the discharge chambe of fluid
Volume increases.When the pressure of the inside of discharge chambe becomes equal to suction pressureP 2 When, the sucting stage for compressing circulation starts, so as to
Triggering inlet valve is in volumeV 2 Lower opening.During sucting stage 2, the amount of compression chamber volume and fluid to be compressed is (in pressure
PowerP 2 ) increase, the maximum volume until reaching discharge chambeV 3 。
Compression circulation compression and during the discharge stage, piston along and expansion and sucting stage during the direction of motion
Contrary direction motion, to reduce the volume of discharge chambe.During compression stage 3, both inlet valve and transfer valve are closed and (are flowed
Body is not entered or leaves cylinder body), the pressure of the fluid in discharge chambe increases (from suction pressureP 2 To discharge pressureP 1 ), because
The volume of discharge chambe is reduced toV 4 .When the pressure of the inside of discharge chambe becomes equal to discharge pressureP 1 When, compress the conveying rank of circulation
Section 4 starts, so as to trigger transfer valve opening.During delivery phase 4, in discharge pressureP 2 Fluid arrange from discharge chambe
Go out, minimum (emptying) volume until reaching discharge chambeV 1 。
One tolerance of the efficiency of compressor is volumetric efficiency, and volumetric efficiency is in sucting stageV 3 -V 2 Period is reciprocating
The volume of the discharge chambe of the piston-swept of compressor with compression circulation during by the total measurement (volume) of piston-sweptV 3 -V 1 Ratio.
It is the gas of the inside due to reciprocating compressor in the phenomenon of the outside generation pressure fluctuation of reciprocating compressor
What the Discontinuous property of stream caused.These pressure fluctuations can cause vibration and fatigue stress is big, noise level is high and compressor
Can reduce.API618 is included in design facility (including reciprocating compressor) and avoids pressure fluctuation with (in addition to other purpose)
Destruction when the detail requirement of acoustic investigation that must be born by.In order to prevent these pulsation from traveling to whole facility, volume
Before bottle is arranged on the inlet valve of compressor and after dump valve, so as to the remainder in reciprocating compressor and facility it
Between enter row buffering.
For example, Fig. 2 shows the simplified model of the interface between reciprocating compressor 10 and the remainder of facility.This
In, term " interface " represents all components between the valve 20 and equipment pipe 30 of reciprocating compressor 10, and gas passes through equipment pipe
30 and be directed into or be guided out the remainder of facility (for example, oil and gas equipment).Reciprocating compressor 10 has piston 40, and
And be connected on volume bottle 60 by pipe 50.Then volume bottle 60 is connected on oil and gas equipment by equipment pipe 30.
Filled with gas to be compressed or compressed gas, (this is before inlet valve depending on volume bottle or arranges volume bottle 60
After going out valve, or whether reciprocating compressor 10 has acoustic impedance), and the reflector as pulsation, so as to only allow
Small part is transmitted to equipment pipe 30.
The frequency of the pressure fluctuation produced by reciprocating compressor 10 is the frequency of the compression process in reciprocating compressor.
When the natural frequency of pipe 30fEqual to the pressure fluctuation produced by reciprocating compressor frequency when, occur resonance.Pipe 50 it is intrinsic
FrequencyfSpeed depending on sound in gascWith the length of pipe 50L.In first approximation, between this tittle below presence
Relation：f=c/(2L).If fixation pressure ripple is formed along pipe 50, can be reduced using restriction (that is, pipe local narrows)
The amplitude of fixation pressure ripple.
Thus, traditionally, pressure fluctuation (is inherently gone out due to the Discontinuous property of the gas stream in reciprocating compressor
It is existing) be dissipated, that is, it is not used.
Constructively using pressure fluctuation, come the method and apparatus for improving the efficiency of reciprocating compressor, (which is arranged on for offer
Including performing in the oil-gas facility of reciprocating compressor or wherein) will be desirable.
