脉动阻尼器使用说明
一、概述
脉动阻尼器又名脉动缓冲器，是消除管路脉动的常用元件，是计量泵必须配备的附件。
脉动阻尼器能够平滑由柱塞泵、隔膜泵等容积泵引起的管路脉动和系统的水锤现象。
它由耐腐蚀的隔膜将气体与管路中的液体隔离，通过气室容积的变化平滑管路脉动。
二、主要功能
1.允许系统使用更小的管径，降低成本。
2.保护管路、弯头、接头不受压力波动的冲击。
3.减小除去水锤对系统的危害。
4.降低系统的能耗。
5.减小流速波动的峰值。
6.为计量泵创造良好的工作环境并改善泵的工作性能。
7.和背压阀等配合使用可以使管路的压力波动接近为零。
三、工作原理
根据玻意耳定律P1V1=P2V2，通过改过气体的体积来平滑管路脉动。
对于流速有正弦曲线特性的系统，波峰时，气室体积变小，脉动阻尼器吸收多余的流量的液体，波谷时，气室体积变大，释放存储的液体，从而达到平滑脉动的效果。
四、产品特点
1.可以预充气体，充气后平滑脉动的效果比空气室式脉动阻尼器的效果好。
2.气体不与管路液体接触；气体不会因溶解到液体里而损失。
3.设有限位装置，防止膜片过度变形。
五、脉动阻尼器的使用
1.使用时压力表指针应小幅摆动，摆动过大则说明预充气体压力偏小或者选型偏小，不。

GENERAL INFORMATIONThis manual provides information on installation, maintenance and field repair for ENIDINE GmbH HD Shock Absorbers.In order to select the hydraulic buffer that best suits your operation, it is important to follow the certified safety standards specified; the selection guidelines provided by ENIDINE and specifics of your particular application. For the bladder type (standard) version, the environment temperature on shock absorber outer cylinder must not exceed 60°C, the temperature of the cylinder must not exceed 70°C during operation. In seldom cases a delay in the return of the piston rod can occur at units resting in a compressed position for long time (Longtime Parking Position). In such cases we recommend to push the rod in the compressed position a few millimetres insuring a proper return.Shock Absorbers for emergency application: In this conditions it is assumed that the shock absorber is not stroked during normal operations. For safety reasons the shock absorber should be checked for functionality (see section “Maintance instruction”) at least every 12 monthsShock absorber used for normal operation:These units should be checked visually (piston rod surface; leakage) and functional (see section “Maintance instruction” ) every 6 month.Based on the cycle rate, in general after 250.000 cycles, a replacement of wearing parts could be required. In general the replacement or an overhaul of the shock absorber is recommended after at least 8 years.ENIDINE makes no express or implied warranties of any kind as to the material contained in the guide. There is specifically no implied warranty of merchantability or fitness for any particular purpose.ENIDINE shall not be responsible for damages (direct, indirect or consequential) and assumes no liability should the guide produce results other than those intended or for the failure of any ENIDINE products due to the misapplication caused by the use of the guide.A properly sized and installed Shock Absorber will perform as expected. If there is anything unique about your application, contact ENIDINE for assistance.We know of no other large-bore shock absorber that can withstand the harsh environments and life-cycling as the ENIDINE design.MAINTENANCE INSTRUCTIONSIt is recommended that preventive maintenance program be established to obtain the maximum life from the shock absorber.A routine inspection should be performed every 6-12 months and this inspection should include the following:1 Stroke in the piston rod completely to check the shock absorber (see “FillingPos.14). Then release the piston rod, it should return to its fully extendedposition. Should the piston rod not return to the fully extended position, thencheck the air pressure in the bladder. Information regarding bladder pressure and oil volume is indicated on the label at the shock absorber as illustrated below.The needed air port adapter is located in the front side of the bearing covered with a plastic cap.2 A visual inspection of the piston rod sealing concerning leakage should beperformed.3 Please contact ENIDINE or your closest ENIDINE representative in case thepiston rod does not return completely in spite of the checks done as per item 1, or if a leakage occurred.The standard shock absorber bladder is pressurised with 3.5 bar air with the piston rod fully extended. The maximum recommended air pressure (with rod extended) is 5.0 bar. The increase to 5.0 bar, under standard conditions, increases the rod return force.Information regarding bladder pressure and oil volume is indicated on the I.D. label at the shock absorber as illustrated:500 cSt Silicon Oil02 :1000 cSt Silicon Oil03 : 100 cSt Silicon OilFIELD REPAIR-INSRUCTIONS HD 2.0DISASSEMBLY1 (Valid for HDA Version only)Insure that the adjustment screw is totally open during the filling respectively depressurisation of the unit.2 (Valid for Bladder Version only)Remove protective cap (36) to access charging valve.CAUTION:DEPRESSURIZE THE SHOCKABSORBER COMPLETELY BEFORE YOU START DISASSEMBLY.3 (Valid for Bellow Version only)Remove the bellow by loosen hose band on the piston cap and on the bearing.4 (Valid for Spring Version only)4.1 Press the spring down towards the bearing and remove cap screw (25) andpiston cap (14).CAUTION:TAKE CARE THAT THE ROD WILL NOT BE DAMAGED BY CLAMPINGWITH A VICE OR A WRENCH.4.2 Uncompress the spring slowly and remove the spring.CAUTION:A RAPIDLY UNLOADED SPRING CAN OCCURE BADLY INJURED.5 Pull the rod (13) out to its max. extended position.

ENGLISHInstallation, Operating and Maintenance Instructions - DS, FG, DP, DV, HG Series UnitsGeneralThese units may be used as Pump Pulsation Dampers, Pipeline Surge Absorbers, Thermal Expansion Compensators or Accumulators and all operate by having a compressible gas on one side of a separating membrane, the other side being connected to the liquid line, used correctly they are totally safe and will give many years of reliable service.SafetyAs with all hydro-pneumatic products great care should be exercised when handling and charging this type of equipment and should only be carried out by trained personnel, as they contain energy in the form of compressed gas.It is essential to read and understand the CA-7 Charging Instructions before any maintenance work is carried out.UNDER NO CIRCUMSTANCES PRE-CHARGE WITH OXYGEN DUE TO THE RISK OF EXPLOSIONIt is however perfectly acceptable for pressures below 7 bar to pre-charge using air pressure from an airline, foot or handpump, and Nitrogen from a high pressure cylinder above this. (Refer to CA-7 Charging Instructions)Unless otherwise specified in your purchase order, a small amount of silicon grease will be used to lubricate the rubber components during assembly at the factory, please check that this will not effect the process or the liquid being handled. When provided lifting eyes or lugs should be used for lifting the unit.Suitable safety devices must be provided :1. To protect the unit from overpressurisation in the event of the liquid line pressure exceeding the design pressureof the unit i.e. pressure relief valve, burst disc.2. Where a risk of fire exists that would cause the gas pre-charge pressure to rise above the design pressure theunit should be protected via the on site deluge system or a suitable safety device must be fitted to the gas side of the unit i.e. fusible plug or burst disc.3. Should the unit be fitted with a heating jacket or trace heated measures must be taken to restrict the heat inputto protect the unit from overpressurisation as in (1) (2) above.4. It is the responsibility of the user to establish a written scheme of examination for the vessel in line with localand statutory regulations for their safe operation. In drawing up the scheme of examination particular consideration should be given to condition monitoring of the membrane, internal and external surfaces of the pressure envelope that may be affected by corrosion, erosion or abrasion.5. Where equipment is installed in potentially explosive atmospheres do not allow dust layers to build up on theequipment. The process fluid temperature shall not exceed the ignition temperature of the dust.6. The maximum operating temperature of this equipment must not exceed the design temperature stamped onthe Vessel or Vessel Nameplate, this is not to be confused with the temperature rating shown on the label for compliance with the ATEX Directive.StorageUnits must be stored in such a way as to prevent mechanical damage to the shell and branch connections, if the unit is to be put into storage for a period of more than 6 months it is advisable to release its gas pre-charge, however where units have a pre-charge exceeding 320 bar g the gas pressure should be released when it is put into storage for a period more than 2 weeks.Store away from extremes of temperature. The bladders are manufactured from elastomers, which may suffer degradation at temperatures below minus 10°C or above 90°C.If the unit has been in use prior to storage then the bladder should be removed and cleaned of any process fluid.Spares Kits should be stored in a dark place in their original packaging away from:-1. Extremes of temperature2. Direct sources of heat.3. Humid conditions which may cause condensation.4. Equipment generating ozone ie. Mercury and high voltage equipment.5. It is recommended that contact between rubbers of different compositions be avoided.ENGLISHPrior To Installation•Check the correct connection has been supplied.•Ensure that the maximum working pressure and temperature to which the unit may be subjected does not exceed the design pressure and temperature stamped on the unit or nameplate. If for any reason the working pressure of the unit cannot be ascertained, then check with our works quoting the serial number on the unit.•Check that the unit is pre-charged. Units are usually supplied already pre-charged and this would normally be marked on the unit. If installation is taking place within 3-4 months of original supply then it should not need checking. If the unit has not been supplied precharged or only has a nominal ‘transit’ precharge (often 1 bar) then pre-charging should be carried out in accordance with relevant Flowguard pre-charging instructions. As a general guide pre-charge pressure should be as follows.•Pump Discharge and Suction Dampers -80% of minimum operating or minimum suction pressure at working temperature. If the precharge of any of your units is significantly different to this or if you have any other queries regarding precharge then contact our works by telephone or fax quoting the serial number.•All units are tested in our works before shipment and traces of test fluid may still be present inside the unit. Test fluid is normally water/oil emulsion. If these traces of fluid are likely to cause any problems when mixed with your process fluid then the units must first be flushed out at system pressure.MountingGenerally units should be mounted in a vertical position either way up. Most units below size 50 however, can be successfully mounted in a horizontal position. Single ported dampers should be fitted on a ‘Tee’ as close as practicable to the pump, keeping the length of the branch as short as possible, the longer the branch the less effective the damper will be.NOTE: Unless stated otherwise on the order, we have made no allowances for supporting the damper. The installer should support the damper and pipework in such a manner as to prevent excessive loadings or stresses on the vessel and branches.After Installation•Ensure that the charging valve cap is hand tight. This cap contains a seal that is the main defence against loss of gas through the charging valve core. The valve core, a non-return valve, which prevents gas loss in the short term, can leak over a long period.•Using soapy water (50% washing up liquid is ideal) check the charging valve, charging valve cap and the whole vessel end for any signs of gas leakage. This is best done with the unit at normal working pressure but it is usually effective if carried out at precharge pressure.•If a pressure gauge is fitted to the pump watch the needle closely when the pump is first switched on. As pressure builds up the flickering of the needle due to pulsations should cease or be considerably reduced as the precharge is reached. In the absence of the correct precharge checking device this is a reasonably accurate way of checking the precharge.MaintenancePulsation Dampers need very little maintenance. The gas precharge should be checked periodically to ensure that no leakage has taken place, using charging kit CA7. It should be noted that when checking the pressure, a small amount of nitrogen is released from the vessel into the charging assembly and its connecting hose. This will cause the reading to be slightly low.Any small losses in precharge pressure may also be due to temperature variations. If small losses are detected the pressure should be topped up. If, however, losses are significant or persistent the cause of the leak should be ascertained and a repair affected.Extreme caution should be exercised during disassembly when the vessel has been used on corrosive or toxic substances as, even after flushing small amounts of fluid may remain, particularly if the bladder is punctured.ENGLISHDisassembly•Prior to disassembly ensure that the unit is isolated from the process line or the process line is depressurised and drained down.•Release the gas using a suitable charging assembly (see leaflet CA7).•Remove gas bladder from gas chamber as follows:•Remove charging valve (Fig 1)•High pressure units (type HG) are fitted with a threaded retaining ring, which may be removed with a peg spanner.Other units (types FG & DS) are fitted with a split retaining ring which should be removed by tapping gas header down bore with a soft faced mallet until retaining ring is fully exposed (Fig 2). The segmented ring (Fig 5) may now be removed from the groove by sliding rings together to form a gap (Fig 6), slide one segment out of the groove with a screwdriver (Fig7) and then lift out of groove (Fig 8). For types DP the construction is the same as FG/DS except that the retaining ring is replaced by a single piece of spring material.•Fit extractor bolt with suitable mating thread into charging valve hole (Fig 3).•Header plug may now be levered out using two levers to ensure that header plug remains square to the axis of the bore. On the larger sizes it may be necessary to use spacers on end of shell to give enough clearance (Fig 4). •Bladder may now be removed from gas header plug, on units larger than size 50 the button and backing washer, closing the end of the bladder, should be removed and retained for fitment to the replacement bladder.Reassembly•It is recommended that the inner and outer seals be replaced each time the damper is stripped down.•On units above size 50 the original button and backing washer should be fitted with new seals and assembled onto the bladder.•Assemble bladder onto gas header ensuring that the inner seal is replaced in the correct position on the gas header and the outer seal is correctly positioned in its groove in the shell.•Smear the outer seal and top of the bladder with a lubricant, which is compatible with the bladder and the process liquid. Silicon Grease is used at the factory unless otherwise stated on your purchase order.•Assemble bladder and gas header into bore of shell.•High Pressure units-Tap gas header down bore with a soft-faced mallet until the retaining ring thread is fully exposed.Do not use the threaded retaining ring to force the gas header down as this can cause the threads to gall.•Low Pressure units-Tap gas header down bore with a soft-faced mallet until retaining ring groove is exposed. The segmented ring, may now be fitted into the groove.•Fit extractor tool with suitable mating thread into charging valve hole (Fig 3).•Header plug may now be levered up using two levers to ensure that the header plug remains square to the axis of the bore and the retaining ring segments are seated correctly.•Replace charging valve and recharge damper with nitrogen to the pressure specified on the label.•Replace weather protection cap if supplied.•Suction Dampers, which may work at pressure close to, or below, atmospheric pressure, may be fitted with screws and washers to prevent the gas header from being sucked down the bore. These must be refitted after maintenance. •Dampers, which may be subjected to high compression ratios, may be furnished with a cushion fluid on the gas side of the bladder. The volume of fluid to be used is normally 25% of the nominal volume. The fluid used should be compatible with the system fluid in order to avoid any problems in the event of bladder failure.ENGLISHBasic Accessories and sparesDescription Part NumberStandard 1215 stainless steel charging valve – BSP thread SK-CV-1215/B Standard 1215 stainless steel charging valve – UNF thread SK-CV-1215/U Low Pressure Adaptor, allows 1215 valves to be charged using a foot pump SK-AD-15/11 Levers Set Short (300mm) for removing gas headers SK-TL-LVR/S Lever Set Long (450mm) for removing gas headers SK-TL-LVR/LGas Headers Extractor with 1/4” BSP Thread SK-TL-GHX/BGas Headers Extractor with 1/2” UNF Thread SK-TL-GHX/URings SK.TL.PSRRetainingPeg Spanner for removal of ThreadedENGLISH1.
