高压恒流泵检查步骤
高压恒流泵检查步骤高压恒流泵检查步骤一、LC-P100高压恒流泵右侧面示意图二、将流动相瓶（流动相需预先过滤并脱气）放在实验台台面上（不能放在仪器顶部）。
三、将与泵的输出口（也就是上图中的高压液流输出口，下同）相连的镙帽旋开，在泵的输出口位置接一根PEEK管（长度不限）。
四、打开排空阀，用针筒从排空管的出口端缓慢抽出约15毫升的流动相（针筒抽的同时需要将PEEK管的出口端用手指按住），以排出泵头内部的气泡。
（如果没有流动相被抽出，说明单向阀堵塞，请处理单向阀后再重复本步骤的操作，正常后再进行下一步操作。
）注：多数时候都是输入单向阀堵塞，请先处理输入单向阀，必要时再处理输出单向阀。
五、关闭排空阀（不能连接色谱柱）。
打开泵电源，按“设置”键7次，选择冲洗功能，排出泵内部管路中的气泡（注：冲洗时不接色谱柱，否则将冲坏柱子）。
观察是否有连续的液体流出？如果流动相是连续地流出，进行下一步检测；如果流动相断断续续地流出，说明某一个单向阀工作不正常（请处理单向阀后再进行第四步操作）。
六、通过仪器面板上的按键来设置流量为1毫升/分钟。
按“启动”键。
观察PEEK管的出口处是否有液体滴出（约2-3秒钟1滴，PEEK 管的出口端的水平高度应高于流动相瓶内的液位高度）。
如果有液体滴出，直接进行第八步操作。
如果没有液体滴出，进行下一步检测。
七、打开泵的机壳，观察电机是否转动（此时泵应处于运行状态）？如果电机没有转动，一般需返厂检修（请与我公司技术人员确认后再寄回我公司）。
如果电机在转动，进行下一步检测。
八、在PEEK管的出口端接一根色谱柱，色谱柱的出口处接到废液瓶。
设置流量为1毫升/分钟，按“启动”键。
观察色谱柱出口端是否有流动相滴出？观察柱压情况。
正常的情况应该是柱压先缓慢升高，然后稳定（压力稳定后脉动一般不超过0.2MPa），同时色谱柱出口端有液体流出，说明泵已工作正常，无需进行下面的测试，按以前的方式将管线连接好后即可。

恒流泵使用步骤及注意事项 恒流泵如何操作
恒流泵使用步骤及注意事项恒流泵如何操作恒流泵是一种可定量加液或抽液的科学仪器，该仪器具有：输送流量稳定、连续可调、输送物质不与外界接触，可防止污染及体积小、重量轻、性能牢靠等优点。
因此，恒流恒流泵是一种可定量加液或抽液的科学仪器，该仪器具有：输送流量稳定、连续可调、输送物质不与外界接触，可防止污染及体积小、重量轻、性能牢靠等优点。
因此，恒流泵广泛使用于各厂矿企业、大专院校、医院及科研单位,并成为生产和科研试验中必不可少的仪器设备之一，凡是需要微量、定量输液或抽液的场合均可使用。
恒流泵使用步骤：1、在第一次使用恒流泵的时候，首先将调速旋钮调到最小位置，然后接通电源，此时指示灯亮、“T”字轮开始运作，调整调速旋钮，察看仪器转动是否正常，正常后即可使用。
2、流量是由调速旋钮来掌控，流量可在1—600毫升/小时范围内连续可调。
3、调距板（即泵头前后的滑动板）的调整螺丝是用于调整液体压力的，一般只要拧到有液体流动即可，调整时需要注不要拧的太急、太紧，否则滚子会拧死。
4、使用恒流泵的顺逆开关，可以更改流量反向，会使加液体更改为抽液，加压更改为抽压。
5、加速（按钮）开关的作用紧要适用于在较慢转速时不更改原来流量清洗管道时使用。
6、依据需要可在硅胶管两端再接上其他管子，将液体输送到需要的地方去。
恒流泵备有两种规格的管子，可依据流量需要选用，使用粗管子时，只要将粗管子置于粗管槽内即可。
恒流泵使用注意事项：1、使用恒流泵时调压板不要请不要在拧得太紧，以免“扎死”泵头，一般调到有液体流出即可，以免泵头，硅胶管在泵头内部应涂上润滑油，以延长其使用寿命。
2、泵头在快速运转中，切勿按动“顺/逆”开关，若要按动，则先将速度调慢后再按动，然后再将速度至原来速度，即将电压表读数调至原来值。
3、恒流泵在使用期间，应随时注意硅胶管是否完好，一般在中速情况下运转为佳，当发觉硅胶管使用老化时，应适时更换硅胶管。
当恒流泵开始运转时，硅胶管可能有向一端肿起现象，可用手拉直即可。

The definitions of the three signal words are as follows:Special notes intended to bring attention to procedures that must be followed to ensure proper installation and performance will be placed in a box labeled NOTICE.Section 4.0The pump has been assembled and pressure tested at Examine all material within the container and checkSee assembly drawing for product specifications:- Pump Geometry- Pump Materials of Construction- Maximum Allowable Working Pressure- Maximum Working Temperature- Pressure Ratio- Displacement- Repair Kit Part Numbers- Torque Information- WeightsUnpackingParker Autoclave Engineers and is ready to be put into service. The shipping carton should be opened and the contents carefully examined upon receipt from the carrier. Make sure there is no obvious damage to the contents. DO NOT use the equipment if any damage is evident. If damage has occurred, file a claim with the shipper before contacting Parker Autoclave Engineers Service Department.against the packing list to be sure all items are accounted for and are not damaged. Verify that the equipment model number supplied agrees with what was ordered.Section 4.0UnpackingAt minimum, the tools required for installation of the pump include a torque wrench, an open end wrench adapter (crows foot adapter) and an open end adjustable wrench. Refer to the Tools, Maintenance and Installation Manual provided with the Data Book for information on torque wrenches and torque values for Parker Autoclave Engineers tubing and fittings.Section 5.0ToolsOperation & Maintenance InformationOperation & Maintenance Manual | 04/22 02-9242ME: AHL Series Pump02-9242ME : AHL Series PumpOperation & Maintenance Manual | 04/227Section 6.0InstallationSection 6.1Compressed Air SupplyUnless otherwise noted, all air line accessories for the pump air drive should have, at minimum, a 1/2" FNPT connection. The tubing/piping used to connect the components should have the maximum ID the pressure rating will allow. Reducing the size before the air inlet will reduce air pressure flow andreduce flow rate of the pump.NOTICEThe main air drive connection port on the pump is afemale 1" FNPT and is located in the spool base housing. An additional female 1/8" FNPT air pilot valve connection port is located in the middle plate at the opposite side of the 1" NPT air inlet.This pilot connection must be plumbed to an unregulated and filtered air source. The purpose of this connection is to aid in low pressure differential start-up and restart of the pump while providing a more accurate pressure control. The pump will not function if this unregulated air supply is not connected to the pilot valve supply port.The use of an air line lubricator is not required and is not recommended. The oil in the air lubricator will cause the factory installed grease to be purged from the pump. Once an air lubricator is used the pump can never again be operated withoutan air lubricator.NOTICEAn air line filter with a minimum 5 microns filtration rating must be used on the supply line. If the air supply is not dry, a mist separator must be used to remove moisture in the air line.The pump is designed to function from 20 psi to 110 psi (1.4 to 7.6 bar) air input pressure, however maximum inlet air pressure is limited by the maximum liquid output pressure.Operation & Maintenance Manual | 04/2202-9242ME : AHL Series Pump8Section 4.0UnpackingAll AHL series pumps have high pressure liquid outletports located on the side of the pump head’s. The suc-tion inlet ports on all AHL series pumps are positioned opposite of the inlet checks.Inlet: A liquid filter with at least a 100 mesh size must be installed before the suction port inlet to preventdamage to the check valves and high pressure seals due to debris.Section 6.2Liquid Section For best performance, a liquid supply reservoir should be located higher than the inlet gland on the pump to create a small pressure head. Be sure to make an air tight seal between the reservoir and the pump inlet connection. The connections between the reservoir and pump inlet should not be reducedfrom the FNPT connection size.NOTICERefer to product literature for inlet connection details for each pump. The tubing or piping should be made from a corrosion resistant material and sized with a maximum ID to fit the inlet pipe connections.Restricting flow at the liquid inlet will cause problems with check valve performance and reduceoutput flow.NOTICEOutlet: The outlet tubing ID must, at minimum, match the same size of the pump check valve gland port. Refer to product literature for outlet connections details for each pump. Reducing outlet tubing or connection will reduce output liquid flow capacity.Section 4.0UnpackingSection 7.0Pump Start-Up Air Line SchematicAs shown above, a filtered main air supply line is required. The air line then must be split through a tee. One line will attach to the 1/8" FNPT pilot valve connection in the middle plate of the pump.The air pressure on this connection must be higher than the regulated main air supply on the air drive section. The second line out of the tee will go to a pressureregulator which can be set to achieve the desired output liquid pressure according to the pressure ratio of the pump.In order for the pump to flow properly, both outletsmust be plumbed together into a tee to onesingle outlet.NOTICEAIR02-9242ME : AHL Series PumpOperation & Maintenance Manual | 04/229The pumps unique design allows for self priming.To prime, regulate the air pressure to between 5-15 psi or use an air flow regulator to reduce to a slow stroke frequency. With the high pressure side connected to a vented system, allow the pump to cycle till a consistent flow of liquid is achieved. Let the pump flow freely to purge any air in the liquid system. Loosening the outletgland or pipe can also assist in priming the pump.Increase the air pressure using the air pressure regulator until you achieve your desired output liquid pressure. At this point the pump will stall. You can calculate the output pressure by multiplying the input air supply by the actual pressure ratio of the pump. The pump will automatically restart if there is a drop in downstream high pressure.Section 4.0UnpackingSection 8.0Process Media Parker Autoclave Engineers pumps discussed in thismanual are used for pumping oil, water and oil/water mixtures. Special seals are also available for chemical service. Please contact Parker Autoclave Engineers todiscuss availability of special seals.Pumps are not designed to run for long periods of time without liquid process media. Short, dry pumping cycles should not be a cause for concern.However, pumps are built using lubricant in the seal areas and pumping without fluid will wear away lubricant and compromise the seal .The operating temperatures of the pump are between 0°F to 140°F (18°F to 60°F).Operation & Maintenance Manual | 04/2202-9242ME : AHL Series Pump10Section 4.0UnpackingSection 9.0Pump Functionality When the pump is installed, maximum system air isconnected to 1/8" FNPT pilot air inlet and is sealed off by pilot valve assembly in the top end cap and does not enter the spool housing. Regulated air is connected to the spool housing at the 1" FNPT pump inlet.1. Regulated inlet air pressure enters the spool housing and is diverted to the air cylinders and their pistons, which causes one p lunger to build pressure in one of the hydraulic pump heads while the second plunger performs asuction stroke that will pull liquid into the second hydraulic pump head.2. When a hydraulic pump head is in the suction stroke, the plunger is moving away from the head causing the inlet check valve to open, which allows liquid to be drawn into the head while the outlet check valve is forced closed.3. When the hydraulic pump head is buildingpressure, the plunger is moving toward the head compressing the fluid and forcing the inlet check valve to close and the outlet check valve to open.4. The air pistons continue to move until a pistonhits the pilot valve assembly in the end cap.5. The pilot control valve shifts allowing max system air pressure to shift the spool valve so that it now directs air drive pressure through to the opposite side of the pistons in the air cylinders and pushes the air piston and liquid plunger in the opposite direction.6. While the air drive pressure is acting on the pressure side of the piston, the opposing area of the piston’s are vented through the exhaust mufflers.7. This action causes the reverse action of step #1 (the suction head will change to acompression stroke, while the pressurize head will change to a suction stroke).8. The air pistons continue to move until a piston hits the pilot valve assembly in the second end cap which will again cause the spool to shift and divert air to move the pump in theopposite direction.Section 4.0UnpackingSection 10.0Suggested MaintenanceA.Before each pump use, a quick inspection should be performed to insure there are no loose bolts, nuts, set screws or check valve glands. Tighten any lose bolts and fittings according to the torque values listed on the pump assembly drawing. A visual inspection should also be made before each use and at startup to make sure there is no evidence of fluid leaks from isolation chamber drain ports, check valves connections and muffler. If liquid mists out of the muffler for more than 5 strokes, it is time to replace your hydraulic high pressure seals. Refer to the troubleshooting guide for solutions to these fluid leaks.B.The maintenance schedule of the pumpdepends on the frequency of use, cleanliness of media, type of media, cycle rates, output pressures, cleanliness of air or any other conditions that may be damaging to sealintegrity. Once a clear pattern develops of how long a pump is in service before pumpperformance declines, it is recommended to perform maintenance in advance of this time frame. At minimum, perform maintenance on the pump once a year as described below.9. This alternating action of steps #1 to step #8 continues until the maximum outlet hydraulic pressure is reached based on the pressure ratio of the pump.02-9242ME : AHL Series PumpOperation & Maintenance Manual | 04/2211Maintenance would include:• Re-lubrication or replacement of spool valve o-ring• Re-lubrication or replacement of air drive seals• Re-lubrication or replacement of pilot valve o-rings and gaskets• Replace check valve components • Replace high pressure hydraulic sealsC.Maintenance instructions are supplied with appropriate rebuild kits.

Cause: a) Spool valve o-rings are leaking. b) Spool sleeve o-rings are leaking. c) Outside o-ring(s) on air piston(s) is leaking. d) Seal between air piston and liquid plungeris leaking.Solution: a) Replace and lubricate spool valve o-rings.b) Replace and lubricate sleeve o-rings.c) Replace and lubricate air piston o-ring(s). d) Replace o-ring on bottom plunger (two piece plunger designs), or add Loctite 2760 thread locker with sealant on plungerthreads (one piece plunger designs).Problem: Pump will not run and air escapes through the small hole in the spool valve housing.Cause:Spool valve sleeve o-rings are leaking.Solution: Replace and lubricate spool valve o-rings.Problem: Pump will not run and air escapes through the pilot valve vent in the bottom end cap.Cause: Pilot valve gasket or o-ring is not sealing inthe bottom cap.Solution: Replace and lubricate pilot valve gasket and o-ring. If necessary, also replace the tappet rod.Problem: Pump operates at a high frequency and short strokes.Cause:The top or bottom pilot valves are defective.Solution: Replace and lubricate both pilot valve gaskets and o-rings. If necessary also replace the tappet rods.Problem: Pump will not run and air flows out of the separation plate vent (double stage pump only).Cause: The rod seal in the separation plate is leaking.Solution: Replace and lubricate rod seal assembly.Problem: Pump functions slowly or doesn’t operate at all.Cause: a) Condensation from air supply is freezing the spool valve.b) Air muffler is clogged.Solution: a) Stop pump for a short period and replace or add a mist separator in the air line. b) Clean or replace air muffler.Operation & Maintenance Manual | 04/2202-9242ME : AHL Series Pump16Section 4.0UnpackingSection 14.0Troubleshooting - High Pressure, Liquid Section Problem: Pump does not produce liquid flow, operates irregularly or does not maintain pressure.Cause: a) Air in the hydraulic system. b) Suction line excessively long. c) Suction tubing sized too small. d) Failure of one of the check valves. e) Liquid inlet filter is blocked.f) High pressure seal excessively worn.Solution: a) Check inlet suction line and connections for leaks and allow pump to flow freely downstream so as to remove any air. b) Shorten liquid supply line.c) Increase tubing ID size between reservoir and pump inlet.d) Clean or replace both inlet and outlet check valve assemblies. e) Clean or replace liquid inlet filter.f) Replace high pressure seal assembly.Problem: When air is applied to pump the spool will not actuate.Cause: Unregulated air pilot feed line pressure was shut off at the same time as regulated main air drive pressure. This caused the Pilot Control Valve to stop in an incorrect positionat shutdown.Solution: Assure unregulated pilot air, regulated air drive and shutoff valve are arranged as shown in the “Air Line Schematic” in Section 7.0.Turn off regulated air drive pressure.Pressure should now only be supplied to the unregulated pilot connection.Press the manual push button switch on either end of Pilot Control Valve (see image below). This will shift the Pilot Control Valve and then the spool to the position required for restart. Now supply pump with main regulatedair pressure.Pilot Control ValveSection 4.0Unpacking Section 15.0ServiceParker Autoclave Engineers now require all pump repairbe sent to an authorized repair facility.

简介微型高压输液泵输送的流动相可能会使用有机酸、有机碱、无机酸、无机碱等腐蚀性液体，为避免次生杂质对分析带来影响，设计中尽可能的采用相对惰性的材料，接触流动相的介质有：经钝化处理的316不锈钢、PTFE、PEEK等。
该产品的压力范围为：10mL泵头：0～45MPa，流速范围0.01～9.99mL/min；50mL泵头：0～25MPa，流速范围0.01～49.99mL/min。
该产品为双柱塞串联式往复泵，采用了先进的电子脉动抑制技术，这样很大程度上消除了凸轮脉动对输液泵流量的影响，大大地保证了流量的准确性和稳定性。
电子脉动抑制技术的采用，取代了传统的机械缓冲器，彻底解决了由于机械缓冲器频繁泄露所导致的重大故障。
同时也使得输液系统的死体积降到了最低。
该产品的输液结构模式为串联式。
较并联式结构少两只单向阀，进而由单向阀故障所导致的系统故障率会减少50%，至于并联式结构交替供液所产生的流速波动同样需进行进一步的抑制，就并联式结构本身来讲并不能彻底根除流速的波动。
该产品在不同的色谱柱阻尼下流动相的输送效率问题（单向阀的启闭、流动相的压缩性等）由相应的参数进行自动调整补偿，以保证色谱系统流速的稳定性。
该产品的流速范围可通过更换泵头及相应的系统参数进行调整。
即可由10mL的分析型轻松转换为50mL的半自备型。
该产品可通过RS232/485接口由色谱工作站进行控制。

旋松旋松冲洗阀旋钮，按“Purge”键，启动冲洗，再按“Purge”键停止冲洗。
冲洗工作结束后拧紧冲洗阀旋钮。
！ 注意：在旋松冲洗阀旋钮时，会有流动相从前端孔内流出，可用备件中手拧PEEK接头及PTFE管将该液流倒入废液瓶。
如图所示。
若吸液管内大面积充满气泡，或希望更快速使泵头充满流动相，可辅助使用备件中60mL注射器及手拧PEEK接头，如图示旋入冲洗阀旋钮前端的孔内，再拧松旋钮，抽动注射器，此时流动相会经由泵头抽入注射器，以达到快速换相。
结束后再旋紧旋钮，此时可取下注射器。
！ 注意：用注射器快速换相时，泵出口应连接色谱柱，或将泵出口进行封堵。
柱塞的后冲洗柱塞的后冲洗可除去柱塞后部的缓冲盐等结晶体或其他颗粒性杂质。
清洗液的选择可根据流动相的性质来选择。
比如流动相是缓冲盐时，可使用二次水来清洗（若长期使用，可加入10%左右的甲醇或异丙醇，以防止二次水变质）。
输液泵与计算机的连接高压输液泵可以通过RS-232/RS-485串行接口与计算机实施通信。
串行接口位于仪器后面板。
维护拆卸泵头部件！ 注意：残留在泵头中的有机溶剂，可能会刺激皮肤，影响健康。
用合适的溶剂（如甲醇等）冲洗泵头，再换用二次蒸馏水冲洗十五分钟。
然后再进行泵头的更换和维护工作。
操作：9将输液泵所连接的流动相溶剂瓶置于泵头水平面以下，松开图2 -12）处的“吸液管”。
9用扳手松开图2 -5）所示“连接管”。
9用S=3的六角扳手松开“图2 -9）泵头安装螺钉”，并移除泵头安装螺钉。
！ 注意：在拆卸“泵头安装螺钉”时，应用一只手握紧泵头，另一只手用六角扳手慢慢拧松螺钉，并且应按对角线轮流松动四个螺钉，每次松动大约半圈，直到把四个螺钉同时拆除。
