液压柱塞泵压力变化速率问题探讨,作者:马明东
答疑解惑11\10作者:马明东这次利用2020年的PTC国际液压展会期间,与液压界的一些牛人会面时,大家探讨了一下各自感兴趣的液压课题,与高手过招,收获至丰,受益匪浅。
例如,我提问一个问题,德国力士乐液压泵样本上有这么一段话;压力变化速率R A max-----16000bar/s。
压力变化速度R A、在整个压力范围内压力变化的最大允许升压/降压速率。
这段话,我所不解的是力士乐要表达什么意思?为什么要在样本上特意标注这么一项技术要求?如果柱塞泵超过了这项技术要求是什么后果?我查百度解译的意思是:速率;速率是物体运动的快慢,即速率是速度大小或等价于路程的变化率,它是运动物体经过路程Δs和通过这一路程所用的时间Δ的比做。
按照每秒压力变化速率为16000bar/s,哪么每ms为压力升/降16bar,即是一台柱塞压力从0ba上升到400ba时,所用时间为:25ms,如果泵是电机带动的,每分钟为:1500r pm时,25ms时间内,泵缸体只旋转了225°,还没有旋转一圈,只有5.6只柱塞各压缩油液一次,这是不可能的泵的压力上升速度能达到的这么高的速率的,出非是极小的容积,这对液压系统中应用的柱塞泵不会出现这样的速率,哪只是压力冲击到泵内。
石景林老师对此讲了一个实例:讲的是一个百吨吊车在起吊重物时,中途停止起吊时,所吊的重物对吊车的钢丝绳一戥,产生的压力冲击反馈到泵的压力输出口内,压力冲击是泵输出压力的几十倍。
这种现象是很多搞液压的人不理解的,只有做过压力测试的人才能体会的,下面是石景林老师对泵的P口压力冲击所做的测试曲线图,在所测试的此曲线图上可看到1ms时间内,压力速率是26.5bar。
瞬间的压力变化速率导致的后果会已出现对泵损坏实例太多了,有一次是A4VSO355泵壳体P口出现裂纹。
我个人认为,石老师的曲线图的压力梯度变化是太小了,有比这还要大几十倍甚至百倍的压力梯度变化的,作者本人也做过测试,所测试的压力梯度变化曲线图也发表在别的文章中,本人还经历过一次0~600bar压力传感器直接爆坏过的事情,最真接的实际证据是压力冲击对泵壳体后盖、对泵配流盘,以及对泵缸体、柱塞、滑靴冲击损伤的照片,关于变类的照片我会拿出几百张的,下面就发表几张作为补证。
液压系统介质为水乙二醇需要注意
关于水乙二醇液压系统问:液压系统介质为水乙二醇需要注意什么由于需要,一液压系统介质需用水乙二醇,请问元件选型等设计需要注意什么和液压油有什么区别答:密封不能用脂类密封,只能用橡胶的还有就是注意下泵,能不能泵水乙二醇其他的跟液压油区别不大问:液压系统使用水乙二醇的利弊答:防火.抗爆炸.对密封件和电磁阀的要求较高.对环境污染小答:液压原件使用寿命缩短20%~50%,关键件是专用的,比如液压柱塞泵就是特殊的,泵内的零件也是专用的,泵的轴承是水基轴承.答:同时柱塞泵的最高使用压力将大大降低,一般重载泵压力不超过25MPa。
答:4楼的“液压青年”,柱塞泵是不可以用水乙二醇等乳化液的,这种水乙二醇水乳液多用于压力较低的场合,或用于压力的间接传递。
现在用于高压的水乙二醇液压泵等系统应该说在世界上还没有成熟的产品。
答:优点:防火.抗爆炸.缺点:对系统抗腐蚀能力要求高,对密封要求高,系统精度保证难度大!价格高!答:使用水乙二醇的系统,一般用于炼钢、高炉等高温、高火情的设备,防止由于系统泄露的介质造成大面积的火灾。
但是由于介质的化学性能,首先限制了液压元件的密封材料,需要采用成本比较昂贵的氟橡胶的材料。
其次是由于黏度的问题限制液压元件的结构形式。
另外介质本身需要投入比较多的时间去检验、维护;因为其中的成分随着水分的挥发会产生变化。
润滑性能比较差,使得元件性能、寿命都受到极大影响,所有这些都造成系统运行成本的上升。
答:油缸密封件应该用氟橡胶了,价格贵了问:水乙二醇液压系统最近在设计一个水乙二醇液压系统,我们知道这样的介质对密封件的影响不是太大,对轴承的材质影响到是很大的答:水乙二醇对系统要求好像比磷酸酯类宽泛一点,相对普通液压油好像也没有什么特殊的要求吧!希望有高手指导!答:我们有用水乙二醇的液压系统,我觉得主要考虑到系统由于介质黏度低、润滑性不好带来的问题。
水乙二醇系统的液压元件的损坏率很高的。
而且密封也容易老化,但不是主要问题,其中系统的清洁比矿物油为介质的系统要求更高些。

DATA SHEET HyPerforma 100 L Single-Use MixerHyPerforma Single-Use Mixer with Touchscreen ConsoleThe next generation of efficiency and performance The Thermo Scientific ™ HyPerforma ™ Single-Use Mixer (S.U.M.) with Touchscreen Console offers enhanced functionality, ease of use, and efficiency. The complete HyPerforma S.U.M. system consists of a mixer tank, available in 50, 100, 200, 500, 1,000, and 2,000 L sizes, with the Touchscreen Console. The HyPerforma S.U.M. has a 5:1 turndown mixing ratio and maintains traditional stirred-tank mixer design principles with a directly coupled motor impeller drive assembly and a cylindrical tank with a specific height-to-diameter ratio. This allows quick turnaround times for both liquid-to-liquid mixing and powder-to-liquid mixing.100 L HyPerforma S.U.M. standard configurations • DC motor• 3x load cell weighing system • Touchscreen ConsoleCritical upstream application steps • Media preparation • Final formulation steps • Buffer preparation • Large-volume mixingCritical downstream application steps • Pooling and liquid transfer • Product suspension• Mixing and storing multiple batches • Buffer preparation • Viral inactivationTouchscreen Console capabilitiesThe Touchscreen Console offers state-of-the-art in-process monitoring and automation capability for the HyPerforma S.U.M. Its modular design allows for an easy-to-use custom user interface. Capabilities include control of agitationspeed, pumps, pinch clamps, and the temperature control unit (TCU). Users can easily view measurements from load cells, pH sensors, conductivity sensors, resistance temperature detectors (RTDs), and pressure sensors. Simple, routine processes can be automated by utilizing measurement values to control the pumps, temperature control unit (TCU), and agitation motor. The Touchscreen Console can help users semi-automate their formulation, pH, or saline titrations, and viral inactivation processes. This allows users to program their HyPerforma S.U.M. for a process and trust that the measurements are accurate, precise, and controlled. The data measured during a process can be exported remotely via Ethernet, Profibus, or Modbus remote terminal unit (RTU), and can also be accessed locally with a USB flash drive.Note: Models without water jackets include the same features as the water-jacketed models shown here, but without the jacket and inlet/outlet ports. Optional load cells and cable management system are not shown. See the accessories section for more information about these items.HyPerforma S.U.M. design features and options 1.

Pressure sensors are used in the BPC or line sets to monitor the BPC or liquid pressure, respectively. The BPC can be filled with the proper amount of air when using the pressure sensor in the BPC. The liquid pressure module in the Touchscreen Console is used to control a transfer pump, based on the liquid pressure. Optional pneumatic pinch valves can be used on the fill and harvest lines. These valves automatically open and shut when using the fill and/or harvest modules in the Touchscreen Console.Ordering informationpH sensorThermo Fisher Scientific SV51147.02Mettler Toledo SV51147.01Broadley JamesSV51147.03Conductivity sensor JUMO SV51148.01Mettler Toledo SV51148.02Pressure sensor(single-use, included in BPC and/or fluid transfer assembly)PendoTECH 3/8 in.

液压系统介质为水乙二醇需要注意
关于水乙二醇液压系统问:液压系统介质为水乙二醇需要注意什么?由于需要,一液压系统介质需用水乙二醇,请问元件选型等设计需要注意什么?和液压油有什么区别?答:密封不能用脂类密封,只能用橡胶的还有就是注意下泵,能不能泵水乙二醇其他的跟液压油区别不大问:液压系统使用水乙二醇的利弊?答:防火.抗爆炸.对密封件和电磁阀的要求较高.对环境污染小答:液压原件使用寿命缩短20%~50%,关键件是专用的,比如液压柱塞泵就是特殊的,泵内的零件也是专用的,泵的轴承是水基轴承.答:同时柱塞泵的最高使用压力将大大降低,一般重载泵压力不超过25MPa。
答:4楼的“液压青年”,柱塞泵是不可以用水乙二醇等乳化液的,这种水乙二醇水乳液多用于压力较低的场合,或用于压力的间接传递。
现在用于高压的水乙二醇液压泵等系统应该说在世界上还没有成熟的产品。
答:优点:防火.抗爆炸.缺点:对系统抗腐蚀能力要求高,对密封要求高,系统精度保证难度大!价格高!答:使用水乙二醇的系统,一般用于炼钢、高炉等高温、高火情的设备,防止由于系统泄露的介质造成大面积的火灾。
但是由于介质的化学性能,首先限制了液压元件的密封材料,需要采用成本比较昂贵的氟橡胶的材料。
其次是由于黏度的问题限制液压元件的结构形式。
另外介质本身需要投入比较多的时间去检验、维护;因为其中的成分随着水分的挥发会产生变化。
润滑性能比较差,使得元件性能、寿命都受到极大影响,所有这些都造成系统运行成本的上升。
答:油缸密封件应该用氟橡胶了,价格贵了问:水乙二醇液压系统最近在设计一个水乙二醇液压系统,我们知道这样的介质对密封件的影响不是太大,对轴承的材质影响到是很大的答:水乙二醇对系统要求好像比磷酸酯类宽泛一点,相对普通液压油好像也没有什么特殊的要求吧!希望有高手指导!答:我们有用水乙二醇的液压系统,我觉得主要考虑到系统由于介质黏度低、润滑性不好带来的问题。
水乙二醇系统的液压元件的损坏率很高的。
而且密封也容易老化,但不是主要问题,其中系统的清洁比矿物油为介质的系统要求更高些。
