Description
Technical field
The embodiment of the open theme of this paper relates generally to the facility that uses reciprocal compressor in gas industries, and more specifically, relates to the volumetric efficiency that working pressure constructively pulses to improve compressor,, realizes the pulse pressure-charging effect that is.
Background technique
Use compressor must satisfy the industry specific requirement in gas industries, this has considered that for example pressurized gas usually is corrosive and is flammable.American Petroleum Institute (API) (equipment that is used for gas industries being set the mechanism of the industry standard of generally acknowledging) has issued file API618, and it has listed the complete cover minimum requirements about reciprocal compressor.
Compressor can be categorized into positive displacement compressor (for example, reciprocal compressor, screw compressor or stator compressor) and dynamic compressors (for example, centrifugal compressor or axial compressor).In positive displacement compressor, by entrap gas, and then reduce wherein the volume of entrap gas and realize compression.In dynamic compressors, by (for example, rotatable member) kinetic energy being converted to pressure energy and realizes compression in the predetermined position of the inside of compressor.
Desirable compression cycle (development by following the tracks of pressure-volume in Fig. 1 illustrates in the mode of plotted curve) comprises four-stage at least: expand, suck, compression and discharging.When compressed fluid is discharged, be in discharge pressure from pressing chamber when compression cycle finishes
P 1 A small amount of fluid still be trapped within and empty volume
V 1 In (that is, the minimum volume of pressing chamber).During the expansion stage 1 and sucting stage 2 of compression cycle, piston movement is to increase the volume of pressing chamber.When the expansion stage 1 began, delivery valve cut out (suction valve keeps cutting out), and then, the pressure decreased of trap fluid increases because can be used for the volume of the pressing chamber of fluid.When becoming, the pressure of the inside of pressing chamber equals suction pressure
P 2 The time, the sucting stage of compression cycle begins, thereby triggers suction valve at volume
V 2 Under open.During sucting stage 2, the amount of compression chamber volume and fluid to be compressed (is in pressure
P 2 ) increase, until reach the maximum volume of pressing chamber
V 3
In the compression of compression cycle with during the discharge stage, piston along with expand and sucting stage during the opposite direction of moving direction move, to reduce the volume of pressing chamber.During compression stage 3, suction valve and delivery valve are closed (being that fluid does not enter or leave cylinder body), and the pressure of the fluid in pressing chamber increases (from suction pressure
P 2 To discharge pressure
P 1 ), because the volume of pressing chamber is reduced to
V 4 When becoming, the pressure of the inside of pressing chamber equals discharge pressure
P 1 The time, delivery phase 4 beginnings of compression cycle are opened thereby trigger delivery valve.During delivery phase 4, be in discharge pressure
P 2 Fluid discharge from pressing chamber, until reach minimum (emptying) volume of pressing chamber
V 1
A tolerance of the efficient of compressor is volumetric efficiency, and volumetric efficiency is at sucting stage
V 3 -V 2 During this time by the volume of the inswept pressing chamber of the piston of reciprocal compressor with during compression cycle by the inswept total measurement (volume) of piston
V 3 -V 1 The ratio.
The phenomenon that pressure pulsation occurs in the outside of reciprocal compressor is that the Discontinuous property due to the gas flow of the inside of reciprocal compressor causes.These pressure pulsations can cause vibration and fatigue stress is large, noise level is high and compressor performance reduces.API618 is included in the detail requirement of the acoustic investigation that must bear when design facility (comprising reciprocal compressor) is avoided the destruction of pressure pulsation with (except other purpose).In order to stop these pulsation to propagate into whole facility, before volume bottle is arranged on the suction valve of compressor and after expulsion valve, thereby cushion between the remaining part of reciprocal compressor and facility.
For example, Fig. 2 shows the simplified model of the interface between the remaining part of reciprocal compressor 10 and facility.Here, the valve 20 of term " interface " expression reciprocal compressor 10 and all members between equipment pipe 30, gas is directed into or is guided out the remaining part of facility (for example, oil and gas equipment) by equipment pipe 30.Reciprocal compressor 10 has piston 40, and is connected on volume bottle 60 by managing 50.Then volume bottle 60 is connected on oil and gas equipment by equipment pipe 30.
The frequency of the pressure pulsation that is produced by reciprocal compressor 10 is the frequency of the compression process in reciprocal compressor.Natural frequency when pipe 30
fWhen equaling the frequency of the pressure pulsation that produced by reciprocal compressor, resonate.The natural frequency of pipe 50
fDepend on the speed of sound in gas
cLength with pipe 50
LIn first approximation, there is following relation between this tittle:
F=c/ (2L)If the fixation pressure ripple forms along pipe 50, can adopt restriction (that is, the pipe part narrows down) to reduce the amplitude of fixation pressure ripple.
Thereby traditionally, pressure pulsation (occurring inherently due to the Discontinuous property of the gas flow in reciprocal compressor) is dissipated, and namely is not used.
The method and apparatus (it is arranged in the oil-gas facility that comprises reciprocal compressor or carries out therein) that provides working pressure constructively to pulse to improve the efficient of reciprocal compressor will be desirable.
