第二章注入头部件2.1注入头概述连续油管注入器是连续油管作业装备的关键设备，注入器主要功能是夹持油管并克服井下压力对油管柱的上顶力和摩擦力,把连续油管下入井内或夹持不动或从井内起出，控制油管注入和起出的速度。
2.2结构形式的拟定通过对油田连续油管注入头的现场调研，查阅国内外相关文献，多种方案对比，确定注入头设计方案，结构如图2-1、图2-2所示。
由两台同步的可正反转动的液压马达提供动力，链条驱动，带动夹持块夹持连续油管上下移动。
液压马达为低速径向柱塞马达，带有内部实效保护。
两个液压马达通过液压系统达到基本同步，由同步齿轮传动实现链轮的机械同步；由两组胀紧液压缸推动浮动夹块达到链条胀紧的目的；由夹紧液压缸推动夹紧浮动夹块，夹紧装在链条上的油管夹块夹紧油管，通过链条带动夹块实现油管起下动作。
链条上由带有特殊表面形状和处理工艺的夹持块通过链条销轴固定在一起，以适应连续油管的外径，并达到良好的夹持注入的性能，同时达到最小连续油管的夹持变形和最低的附加应力；由压力传感器通过杠杆机构测量连续油管注入和上提力的大小。
注入头的主要设计参数如下：1、驱动方式：液压马达；2、注入最大下入速度：60m/min（1m/s）；3、注入方式：夹持夹块摩擦驱动，链条带动夹块传动；4、链条张紧液缸数：2*2个；5、链条夹紧液缸数：3*2个；6、最大下井深度：4000m；7、测力系统：压力传感器；8、液压马达型号：CA50；9、适应连续油管：Ф31.75mm，Ф38.1mm；2.3结构形式设计说明1、连续油管起下方式作业要求连续油管不断的向油井内注入或起出。
利用夹块夹持油管产生足够的摩擦力，再利用链条输送夹块完成油管的注入或起出。
为了使夹块对油管的夹持应力不超限，必须采用多个夹块夹持。
2、夹块夹持方式因多夹块必须同时夹持，采用三级浮动的多滚子夹头。
为了保证每个夹块都有一个浮动夹头的滚子夹持，油管承受的夹持力足够能产生下入和提升4000m油管的使用要求。

The pump should be serviced by qualified persons only.5.1Mounting LocationChoose an area located near the chemical supply tank, chemical injection point and electrical supply.Although the pump is designed to withstand outdoor conditions, a cool, dry, well ventilated location is recommended.Install the pump where it can be easily serviced.!Mount the pump to a secure surface or wall using the enclosed hardware.Wall mount to a solid surface only. Mounting to drywall with anchors is not recommended.!Mount the pump close to the injection point. Keep the outlet (discharge)tubing as short as possible. Longer tubing increases the back pressure at the pump tube.!Your solution tank should be sturdy. Keep the tank covered to reduce fumes. Do not mount the pump directly over your tank. Chemical fumes may damage the unit. Mount the pump off to the side or at a lower level than the chemical container.!Mounting the pump lower than the chemical container will gravity feed the chemical into the pump. This “flooded suction” installation will reduce output error due to increased suction lift.You must install a shut-off valve, pinch clamp or other means to halt the gravity feed to the pump during servicing.!Be sure your installation does not constitute a cross connection with thePage 44.0UnpackingYour pump package should contain the following:1 - Injector pump with2 pump tube assemblies 1 - suction tube strainer 1 - ceramic tubing weight1 - 5’ Length of clear PVC suction tubing1 - 5’ Length of opaque LLDPE discharge tubing1-Injection fitting with internal back-flow check valve 1 - Mounting hardware kitA-100NPage 5Floor MountWall MountDrill .156 Dia.

Using theincorrect voltage will damage the pump and may result in injury.The voltage requirement is printed on the pump serial label.The pump is supplied with either a ground wire conductor and a grounding type attachment plug (power cord) or a junction box for field wiring.POWER CORD MODELS -To reduce the risk of electric shock, be certain that the power cord is connected only to a properly grounded, grounding type receptacle.JUNCTION BOX MODELS -To reduce the risk of electric shock, be certain that a grounding conductor is connected to the green grounding conductor located in the junction box.Note: When in doubt regarding your electrical installation, contact alicensed electrician.INPUT VOLTAGE 115V AC 60Hz 220VAC 50Hz HOT LEADWIRE NEUTRAL LEADWIRE GROUND LEADWIRE 230VAC 60Hz YELLOW YELLOW YELLOW BLUE BROWN RED GREEN GREEN GREEN MOTOR LEADWIRES90VDC(+) RED(-)BLACKGREENA-100NPage 9WIRING DIAGRAM - Model A-100NA & A-100NCWIRING DIAGRAM - Model A-100NSAC INPUTAC INPUTWIRING DIAGRAM - Model A-100NFACINPUTA-100NPage 105.4How To Install the Tubing and Fittings!Inlet Tubing -Locate the inlet fitting of the Pump Tube. Remove the tube nut. Push the clear PVC suction tubing onto the compression barb of thefitting. Use the tube nut to secure the tube. Hand tighten only.Foot StrainerWeight TubingSuction !Strainer - Trim the inlet end of the suction tubing so that the strainer will rest approximately two inches from the bottom of the solution tank. This will prevent sedimentfrom clogging the strainer. Slip the ceramic weight over the end of the suction tube. Press the strainer into the end ofthe tube. Secure the ceramic weight to the strainer. Drop the strainer into the solution tank.!Outlet Tubing - Locate the outlet fitting of the Pump Tube. Remove the tube nut. Push the opaque outlet(discharge) tubing onto the compression barb of the e the tube nut to secure the tube. Hand tighten only.Keep outlet tube as short as possible.!Injection/Check Valve Fitting Installation - TheInjection/Check valve fitting is designed to install directly into either 1/4” or 1/2” female pipe threads.This fitting will require periodic cleaning, especially when injecting fluids that calcify such as sodium hypochlorite. See section 7.0.Install the Injection/Check valve directly into the piping system.To prevent trapped gasses, install the fitting in an upward direction. Use Teflon thread sealing tape on the pipethreads.Push the opaque outlet (discharge) tubing onto the compres-sion barb of the Injection/Check valve fitting. Use the tubenut to secure the tube. Hand tighten only.Inlet AdapterOutletA-100NPage 11 6.0How to Adjust The Output6.1Fixed Cycle Timer Models -The pumpingmechanism is turned on and off by an electroniccycle timer.The total-time cycle is factory presetand is not user adjustable. The on-time cycle isadjustable from 5% to 100% of the total cycle time(model A-100NS timers adjust from .5 to 6seconds with total time cycle of 60 seconds).Example: If the total-time cycle is 60 seconds andthe on-time cycle is adjusted for 25 percent, thepump will run for 15 seconds and turn off for 45seconds (60 second total cycle). This cycle isrepeated until either the power switch is turned off, the cycle time ischanged or the input power is disconnected from the pump.To adjust the pump output -!Slide the slide clamps to the left only far enough to open the control panel door.!Turn the adjustment knob to the desired percentage of on-time per cycle.Note:When power is applied to the pump, the A-100N will eitherautomatically begin to pump, or maintain power-off status, depending on the power switch status.6.2The speed of the pumping mechanism isTo adjust the pump output -!Slide the slide clamps to the left only far enough to open the control panel door.!Turn the adjustment knob to the desired percentage of speed.A-100N6.3TFD (Tube Failure Detection) - The pump is equipped with a TubeFailure Detection System which is designed to stop the pump and providean open collector (sinking) output signal in the event the pump tube should rupture and chemical enters the pump head. This patented system is capable of detecting the presence of a large number of chemicals including Sodium Hypochlorite (Chlorine), Hydrochloric (muriatic) Acid, Sodium Hydroxide, and many others. The system will not be triggered by water (rain, condensa-tion, etc.) or silicone oil (roller and tubing lubricant). Page 12If the system has detected chemical, thepump tube must be replaced and thepump head and roller assembly must be thoroughly cleaned .Confirm Chemical Detection - To determine if your chemical will bedetected by the system, remove the pumptube and roller assembly. Place a small amount of the chemical in the bottom ofthe pump head - just enough to cover the sensors. Turn on the pump. If the TFD system detects the chemical, the pump will stop after a five second confirmation period. If the TFD system does not detect the chemical, the pump will continue to run after the confirmation period. Carefully clean the chemical out of the pump head being sure to remove all traces of chemical from the sensor probes. Turn the power switch off and on to reset the pump.Open Collector Alarm Output - An open collector (sinking) output signal is provided with the TFD system. (See page 6). Confirm the FVS flow range - The Flow Verification Sensor (FVS) will only function within its operating range. Sensor model FV-100-6V has an operating range of 30-300 ml/min (1-10 oz/min). If the pump’s output is less than 30 ml/min (0.5 ml/sec), the sensor will not detect chemical and a signal will not be sent to the pump.6.4(FVS)Flow Verification System The pump is equipped with aFlow Verification System which is designed to stop the pump and provide an open collector (sinking) output signal in the event the sensor does not detect chemical during pump operation. This could indicate a clogged injection fitting, empty chemical solution tank, worn pump tube, loose tubing connection, etc.The system features an alarm delay time of 6 seconds which allows the pump to clear any gasses that may have accumulated during stoppedoperation.The pump will stop, and the alarm mode activated, if no pulses are received by the pump and the alarm delay time period has ended. Turn the power switch off and on to clear the alarm and restart the pump. The Flow Verification Sensor is sold as an optional accessory.-A-100NPage 13OPERATING FLOW RANGE (ml/min)30-300FV-100-6V 100-1000FV-200-6V 200-2000FV-300-6V 300-3000FV-400-6VSENSORMODEL NUMBER Install the FVS Flow Sensor - The Flow Verification Sensor (FVS) should be installed on the inlet (suction) side of the pump tube. The sensor includes a PVC tubing insert, located inside the sensor’s female thread connection, that is designed to seal the sensor onto the pump tube inlet adapter.Thread the sensor onto the pump tube until the tubing insert is snug against the pump tube inlet fitting - do not over-tighten.Connect the red/white (+), black (-), and bare (signal) wires from the sensor to the red (+), black (-), and yellow (signal) wires on the plug connector.Knock-out the liquid-tite connector mounting hole on the side of the pump enclosure and install the liquid tight connector. Route the wires through the connector and tighten the connector nut. Plug the connector onto the circuit board at the pins marked “FVS”. See page 6.Open Collector Alarm Output - An open collector (sinking) output signal is provided with the FVS system. (See page 6).FVS SensorA-100NPage 147.0How to Maintain the Pump7.1Routine Inspection and MaintenanceThe pump requires very little maintenance. However, the pump and all accessories should be checked weekly.This is especially important when pumping chemicals. Inspect all components for signs of leaking, swelling, cracking, discoloration or corrosion. Replace worn or damaged compo-nents immediately.Cracking, crazing, discoloration and the like during the first week ofoperation are signs of severe chemical attack. If this occurs, immediately remove the chemical from the pump. Determine which parts are being attacked and replace them with parts that have been manufactured using more suitable materials.The manufacturer does not assume responsibility for damage to the pump that has been caused by chemical attack.7.2How to Clean and Lubricate the PumpThe pump will require occasional cleaning and lubricating.The amount will depend on the severity of service.]When changing the pump tube assembly, the pump head chamber, roller assembly and pump head cover should be wiped free of any dirt and debris.]The pump head cover bearing may require grease periodically.Apply a small amount of grease (Aeroshell aviation grease #5 or equivalent) when necessary.]Although not necessary, 100% silicon lubrication may be used on the roller assembly and tube assembly.]Periodically clean the injection/check valve assembly, especially when injecting fluids that calcify such as sodium hypochlorite.These limedeposits and other build ups can clog the fitting, increase the back pressure and interfere with the check valve operation. ]Periodically clean the suction strainer.]Periodically inspect the air vents located under the motor compartment and on the rear panel. Clean if necessary.A-100NPage 15Remove the Old Pump Tube - The pump roller assembly spins in acounter clockwise direction.The pump head inlet (suction) side is located at the bottom of the pump and the outlet (discharge) is located at the top of the pump head.+Release any pressure that may be in the discharge tubing.+Disconnect the suction and discharge tubes from the pump tube.+Remove the pump head cover.+With the pump running, pull the inlet fitting out of the pumphead. Guide the tube counter clockwise away from the rollers. Pull the outlet fitting out of thepump head.Install the New Pump Tube - Be sure the pump head chamber is clean and free of any debris.Remove and inspect the roller assembly. Be sure the rollers spin freely. If required, apply a small amount of grease to the pump head cover bearing. +With the pump running, insert the inlet (suction) side of the Pump Tube fitting into the pump head.+Carefully guide the Pump Tube into the pump head. Stretch the tubeslightly and insert the outlet (discharge) fitting into the upper retaining slot in the pump head.+Place the clear cover on the pump head and secure with three screws.7.3How to Replace the Pump TubeThe pump tube assembly will eventually break if not replaced.The tube has been designed for a minimum service life of 500 hours. However, the life of the tube is affected by many factors such as the type of chemical being pumped, the amount of back pressure, the motor RPM, temperature and others.The pump tube assembly must be inspected and replaced regularly.A-100NA-100N Page 16REPLACEMENT PARTS DRAWINGXPage 17REPLACEMENT PARTS LISTA -002N -7T P u m p T u b e ,N o r p r e n e .43O .D .,131C -330-6N u t ,T u b e ,.37O .D .T

《2024年连续油管注入头系统力学行为仿真》范文
《连续油管注入头系统力学行为仿真》篇一一、引言随着现代工业的飞速发展，连续油管注入头系统在石油开采、地质勘探等行业中得到了广泛应用。
然而，该系统的复杂性和多变性给其设计和应用带来了极大的挑战。
为了更好地理解其力学行为，提高系统性能和安全性，本文采用仿真技术对连续油管注入头系统进行力学行为仿真研究。
二、系统概述连续油管注入头系统主要由油管、注入头、驱动装置等部分组成。
其中，油管负责输送流体，注入头负责将流体注入目标区域，驱动装置提供动力支持。
该系统在运行过程中，受到多种力的作用，包括内外部压力、摩擦力、重力等。
三、仿真模型建立为了准确模拟连续油管注入头系统的力学行为，我们建立了三维仿真模型。
模型中，我们考虑了油管的材料属性、几何尺寸、内部流体性质等因素。
同时，我们建立了注入头和驱动装置的力学模型，以及它们之间的相互作用关系。
在仿真过程中，我们采用了有限元法对模型进行离散化处理，以便更好地分析系统的力学行为。
四、仿真过程与结果分析在仿真过程中，我们首先对系统进行了静态分析，研究了在不同外力作用下的变形和应力分布情况。
然后，我们对系统进行了动态分析，模拟了系统在运行过程中的力学行为。
通过对比仿真结果和实际运行数据，我们发现仿真结果与实际运行情况基本一致，证明了仿真模型的准确性和可靠性。
在仿真结果中，我们重点关注了注入头的力学行为。
我们发现，在注入过程中，注入头受到的力随着流体压力的增加而增大。
同时，由于摩擦力和其他外部因素的影响，注入头的运动轨迹会发生一定的偏移。
为了减小这种偏移，我们可以通过优化驱动装置的设计和调整油管的材料属性来实现。
此外，我们还研究了系统在不同工况下的力学行为。
通过对比不同工况下的仿真结果，我们发现系统的力学行为受到多种因素的影响，包括流体性质、油管尺寸、注入速度等。
因此，在实际应用中，我们需要根据具体情况进行系统设计和优化。
五、结论通过对连续油管注入头系统进行力学行为仿真研究，我们更好地理解了该系统的力学行为和性能特点。

PWR1 and PWR2 dual power inputs can be connected to power sourcessimultaneously. When the primary power source fails (the default setting is PWR1), the system will automatically switch to the secondary power source (PWR2), preventing any power interruption.Both of Power 1 and Power 2 support positive electricity electricity powersystem. Please notice the power system for power 1 and power 2 only acceptpositive electricity power system at one time6. Check the LEDs of PWR1 and PWR2 to make sure that JetCon 1710GP-U isoperating normally.7. Use Category 5e straight through Ethernet cables with RJ-45 connectors toconnect network devices.8. Connect one side of an Ethernet cable with a RJ-45 connector to the JetCon1701GP-U’s Ethernet port (RJ-45 port), and the other side of the ethernet cableto the n etwork device’s Gigabit ethernet port.9. Check the LED indicator of port status (blinking green) on the JetCon 1701GP-U to see if the network connection is successfully established. Power on the PC host, activate the Command Line mode, and ping the connected Ethernet device to see if it responds.9.1 To enable the “Command Line mode”, click Run in the Start menu, typeCommand, and click OK to continue.10.10.1 T ype ping 192.168.1.1 command to check the connection. Here we use IPaddress 192.168.1.1 as an example. Before the testing, be sure your PChost and target device are in the same subnet.11. Power on the host, activate the Command Line mode, and ping the connectedEthernet device by typing “ping –t 192.168.1.1” command to see if it willrespond.12. The parameter-”t” allow you to continue to ping the network device, as shownin the figure below.Before you continue, make sure that both PWR1 and PWR2 are successfully connected to power sources. When PWR1 fails, the LED for PWR1 will go out. At that moment, if the ping command is still replying, then it proves that redundant power input function works normally.13. Exit the Command Line mode, and connect PWR1 power input. At this stage,your JetCon 1701GP-U has been tested and the installation is completed.6. Troubles shooting⏹Make sure you are using the correct DC power suppliers (DC44~57 V) orpower adapters.⏹Select Ethernet cables with specifications suitable for your applications to setup your systems. Ethernet cables a re categorized into unshielded twisted-pair(UTP) and shielded twisted-pair (STP) cables. Category 3, 4, 5 Ethernet cablesare suitable for systems with 10 Mbps transmission speed. For systems with100/1000 Mbps transmission speed, Category 5, 5e, 6 Ethernet cables are thesuitable specifications for this environment. Also make sure that the distancebetween each node cannot be longer than 100 meters (328 feet).⏹If the power LEDs goes off as the power cord plugged in, a power failure mightoccur. Check the power output connection to see if there is any error at thepower source. If you still cannot solve the problem, contact your local dealerfor assistance7.

第二章注入头部件2.1注入头概述连续油管注入器是连续油管作业装备的关键设备，注入器主要功能是夹持油管并克服井下压力对油管柱的上顶力和摩擦力,把连续油管下入井内或夹持不动或从井内起出，控制油管注入和起出的速度。
2.2结构形式的拟定通过对油田连续油管注入头的现场调研，查阅国内外相关文献，多种方案对比，确定注入头设计方案，结构如图2-1、图2-2所示。
由两台同步的可正反转动的液压马达提供动力，链条驱动，带动夹持块夹持连续油管上下移动。
液压马达为低速径向柱塞马达，带有内部实效保护。

链条上由带有特殊表面形状和处理工艺的夹持块通过链条销轴固定在一起，以适应连续油管的外径，并达到良好的夹持注入的性能，同时达到最小连续油管的夹持变形和最低的附加应力；由压力传感器通过杠杆机构测量连续油管注入和上提力的大小。
注入头的主要设计参数如下：1、驱动方式：液压马达；2、注入最大下入速度：60m/min（1m/s）；3、注入方式：夹持夹块摩擦驱动，链条带动夹块传动；4、链条张紧液缸数：2*2个；5、链条夹紧液缸数：3*2个；6、最大下井深度：4000m；7、测力系统：压力传感器；8、液压马达型号：CA50；9、适应连续油管：Ф31.75mm，Ф38.1mm；2.3结构形式设计说明1、连续油管起下方式作业要求连续油管不断的向油井内注入或起出。
利用夹块夹持油管产生足够的摩擦力，再利用链条输送夹块完成油管的注入或起出。
为了使夹块对油管的夹持应力不超限，必须采用多个夹块夹持。
2、夹块夹持方式因多夹块必须同时夹持，采用三级浮动的多滚子夹头。
为了保证每个夹块都有一个浮动夹头的滚子夹持，油管承受的夹持力足够能产生下入和提升4000m油管的使用要求。
为减小油管所受压强，采用三组具有24个滚子的浮动夹头。
3、链条与夹块的连接方式用两条32A链条，每节连接1个夹块，成为双排链条，夹块与链条同时连续运动，这样受力好，提升力大。
4、链条传动方式链条采用径向低速大扭矩柱塞液压马达传动，省去价格昂贵的减速器，又缩小了轴向尺寸，链条带有胀紧装置。
图2-1 注入头图2-2 注入头总体5、夹块机构夹块夹持部分的圆弧与管径相符合，为了提高摩擦系数开有横向槽。
夹块结构随链条在链轮上传动，不能发生干涉。
材料具有足够的硬度，好的耐磨性。
采用低合金钢渗碳淬火处理。
6、链条传动同步要求为了使两个链条运转同步，保证夹块与管子很好的结合，采用相互啮合的齿轮装在链轮轴上。
7、 机架结构为了装配方便，机架采用两块刚度足够的支撑板，通过尺寸精度很高的支撑块支撑。
8、 提升力的测量在注入头下部采用杠杆机构液压缸，连接传感器就可以准确测出提升力。
9、 油管的引导利用装在注入头上方的带滚轮的油管导向架引导油管顺利插入注入头，注入头上下各设一个引导套。
10、注入头的支撑注入头的动力部分装在支撑架中，作业时有四根可以伸缩的支腿支撑。
2.4油管导向架注入头顶部装有油管导向架，用于牵引连续油管从卷筒到链条牵引总成的导入与导出，是由一系列与架垂直的滚子组成的弧形架，为保证连续油管圆滑过渡，滚子间距定320mm 左右，管子在一定的弯曲半径下弯曲，其变形是处于弹性变形范围的。
在弹性极限内，管子能承受最小弯曲半径R 可按下式计算：sEDR σ2=式中 E －管材的弹性模量，Pa ； D －油管外径，mm ；бs －管材的屈服强度，Pa ；现在我国引进的连、续油管管材一般为ASTM ，A-606钢，其中бs =482.58MPa ，E ＝208.34GPa 按上式计算411in 、211in 油管的弯曲半径见表2-1。
表2-1 连续油管弯曲半径如果管子弯曲时弯曲半径小于表2-1所列的值，那它将产生塑性变形。
我国各油田引进的能适应411in 、211in 油管的连续油管作业机的卷筒半径和导向架半径都远远小于其最小弯曲半径，可见连续油管在起、下作业时均将发生交变的弯曲塑性变形。
但是，管子只是在瞬时处于弯曲塑性变形。
为在运输中减少空间，以及根据现场测绘进口的导向架内侧半径1100mm ，设计的油管导向架内侧半径1100mm 。
外侧弯曲半径1237mm ，前端采用折叠式，结构如图2-3。
图2-3 油管导向架2.5链条载荷2.5.1链条所受载荷分析注入头链条上所受的载荷主要是油管上的轴向力(上顶力、油管重力和油管运动的摩擦力)及链条与夹紧压块间的摩擦力。
(1)油管的轴向力油管的轴向力主要有油井压力对油管的上顶力、下人井内油管的重力、油管在井内产生的摩擦力和油管与防喷器胶心间的摩擦力及油管运动产生的动载荷。
在起出或注入油管的过程中，轴向力随井内油管的深度变化而变。
为防止井下压力窜到地面，通常在油管下部加装一个单向阀，所以认为油井内的上顶力作用在油管底部。
考虑到连续油管在下入和起升时，基本上是匀速运动，动载荷较小忽略不计。
设油管下入深度为L ，油管在井内的上顶力为井深L 处的液压力乘以油管外径的横截面积，这时油管的轴向力可表示为:'2202)(4)(4m g y F gL d D gL P D F ±--+=ρπρπ（2-1）式中： F －油管轴向力，N ；D －油管外径，m ； P 0－井口压力，MPa ； ρy －井液密度，kg/m 3； g 一重力加速度，9.8m/s 2； L －油管下入深度，m ； d 一油管内径，m;ρg 一油管材料的密度，kg/m 3；F ’ m 一油管轴向运动受到的摩擦力，N 。
式中第一顶为油管在井内受到的上顶力，第二项是油管的重力，第三项是油管受到的摩擦力，包括油管与井壁和井液间的摩擦及油管与防喷器胶心间的摩擦，下入油管时为正，起出时为负。
F'm 是一个与井眼状况和井液性质有关的参数，要得到精确的计算值是比较困难的，也是没有必要的，一般近似地取F'm 等于油管受到的浮力。
下入油管时的轴向力为：])1(2[42202gL Dd gL P D F g y x ρρπ--+= （2-2）起出油管时的轴向力为：])1([42202gL Dd P D F g s ρπ--= （2-3）由于ρg/ρy>7 ，所以下入油管时注入器需克服的最大轴向力为：02max 4P D F x π=（2-4）起升油管时注入器需克服的最大轴向力为:]gL Dd 1([4max g 2202maxρπ）--=P D F s （2-5） 式中:Fxmax －下入油管时的最大轴向力，N ；Fsmax －起升油管时的最大轴向力，N ； Lmax －油管设计下入的最大井深，m 。
显然，注入器在设计时应考虑克服的最大轴向力为:Fmax=max{︱Fxmax ︱,︱Fsmax ︱} （2-6）(2)链条所受的摩擦力链条在运动时与夹紧压块间存在摩擦力，这个摩擦力的方向与链条运动方向相反，大小应足以克服最大轴向力。
为了可靠地夹紧油管，夹紧压块所需的夹紧力应力:F j =Fmax/f d （2-7） 式中: F j -夹紧压块所需的夹紧力，N ；f d -链条所带油管卡瓦与油管间的摩擦系数， f d =0.5-0.6(s)。
由于有两副链条，每副链条的内周面分别与两侧的夹紧压块发生摩擦，链条所受的摩擦力为:F m =2μ0F j （2-8）式中: μ0－钢-钢滑动摩擦系数。
(3)链条所受的牵引负载链条所受的牵引负载为油管轴向力与链条摩擦力之和:F L =F+2Fmax(μ0/f d ) （2-9）链条所受的最大牵引负载为:F L max= Fmax[ 1+2(μ0/f d )] （2-10）链条的牵引负载是油马达的负载，链条牵引负载的变化直接影响到油马达的工况。
取L max ＝4000m ，ρy ＝950kg/m 3，ρg ＝7800kg/m 3，Po=25MPa ，D=38.1X10－3m ，d=28.1 *10－3m ，f d ＝0.5，μ0＝0.1，分别计算了下入和起升油管时F L 随井深的变化情况如表2-2，表2-3所示。
表2-2下人油管时F L 随井深的变化表2-3起出油管时F L 随井深的变化L 深度的增加而减小，这是因为油管重力随下入深度而增加的数值大于上顶力随下入深度而增加的数值。
由于链条摩擦力是最大下入井深时的油管轴向力确定的，链条摩擦力的存在使链条牵引负载仍然向上，即需要油马达提供扭矩将油管压入井内。
对于外径38.1mm ，壁厚5mm 的油管，下入井口压力25MPa 的井中时，在整个下入过程中，链条牵引负载一直向上，即油马达一直带负载运转，不会出现负扭矩。
从表2-3可见，起出油管时F L 绝对值随井深的增加而增加，且在整个起升过程中一直保持向下，即油马达一直带负载运转，不会出现负扭矩。
所以选液压马达的最大负载要大于213.1KN ，约22吨，为保证安全，设计时按24吨设计。
2.5.2链轮传动设计计算 1．链轮齿数在条件允许的情况下，尽量减小结构尺寸，齿数太少，两轴间距减小，液压马达将无法安装，取上链轮齿数z 1＝14，下链轮齿数z 2＝122．链轮转速min /7.832283.0*min/601r m n ==πmin /9719628.0*min /602r m n ==π3．链条节距p链条传递功率 P ＝F*υ 式中 F －链条载荷（N ）；υ－链条速度（m/s ）；=24000kg*9.8N/kg*1m/s =235.2kw一侧链条传递功率 P 1＝117.6kw 由于一个轴带动2条链条 单个链条的修正功率为P c ＝P 1f 1f 2/1.75 （2-11）式中 f 1－工况系数；f 2－主动链轮齿数系数；查表得 f 1＝1.1；f 2＝1.9P c ＝117.6×1.1×1.9/1.75 ＝140.5k w由修正功率Pc ＝140.5kw 和上链轮的转速n 1＝83.7r/min 查表选节距p 为32A 即p ＝50.8mm 。
