一:磷酸酯合成基础油的性能磷酸酯分为正磷酸酯和亚磷酸酯两类,其中正磷酸酯又可分为伯、仲、叔磷酸酯,适于作合成油使用的主要是叔磷酸酯。
磷酸酯的性能如下:1)物理性能:磷酸酯的密度大致在0.90~1.25kg/cm3之间,挥发性通常低于相应粘度的矿物油,粘度随分子量的增大而增大,烷基芳基磷酸酯粘度适中,并有较好的粘温性能。
2)难燃性:难燃性是磷酸酯最突出特性之一,在极高温度下磷酸酯也能燃烧,但它不传播火焰,着火后会很快自灭。
3)润滑性:由于磷酸酯含有元素磷,是一种很好的润滑材料,可用作极压抗磨剂。
4)水解稳定性:由于磷酸酯是有机醇或酚与无机磷酸反应的产物,故其水解稳定性不好。
在一定条件下,磷酸酯可以水解,特别是油中的酸性物质会起到催化水解的作用。
5)热氧化稳定性:磷酸酯的热稳定性和氧化稳定性取决于酯的化学结构。
通常三芳基磷酸酯的允许使用温度范围为150~170℃,烷基芳基磷酸酯的允许使用温度范围为105~121℃。
6)溶解性:磷酸酯对许多有机化合物具有极强的溶解能力,是一种很好的溶剂。
二:多元醇酯型难燃液压油与普通抗磨液压油的混用问题多元醇酯型液压油(polyol ester,也称为脂肪酸酯型、HFDU型难燃液压油)是由高性能的合成酯与精选的添加剂调配而成,具有铁金属和非铁金属的防腐保护作用,优异的氧化安定作用。
因其很高的自燃点,所以在航空、电力、钢铁冶金等特殊行业被应用,多元醇酯型液压油与液压系统材料有很好的相容性,能与大多数密封材料相容,特别是:丁腈橡胶,氟橡胶,聚四氟乙烯,硅橡胶,氨基甲酸酯(URETHANE)。
但是下列密封件最好不要使用:氯丁橡胶(Neoprene),丁基橡胶(butyl),乙丙烯橡胶(EPR),低密度丁腈橡胶(Low nitrile Buna-N)。
同时,因该种液压液很容易和矿油型液压油互换,且性能优异,有很好的生物可降解性等优点,尽管其价格是矿油型液压油的两倍以上,仍然被使用在许多对于阻燃和环保要求较高的场所。
Injection pumpsMethanolLDHIGlycolwww.process-pumps.deHammelmann offer a wide rangeof high pressure pumps for thechemical, oil and gas industries.Visit our website.Asphaltene InhibitorParaffin InhibitorCorrosion InhibitorScale Inhibitor INNOVATION THROUGH EXPERIENCEHammelmann Injection PumpsCalder offer a wide range of highpressure pump packages incorporatingHammelmann pumps for the chemical,oil and gas industries.Visit our website.www.process-pumps.deLabyrinth sealThis seal design which is absolutely unique to Hammelmann enables safe, reliable, continuous duty operation at pressures up to 3800 bar.The high pressure seal is formed within the minute cylindrical gap between the plunger and the labyrinth insert. The medium pressure is continuously reduced along the sealing surface.A minimum amount of high pressure leakage serving as lubricant is returned to the pump suction chamber.Exclusive sealing systemThe plunger connection to thepower end is self centering thereby drastically reducing sideways forces. This design ensures that there is virtually no contact between the plunger and the labyrinth insert resulting in extremely low component wear.When the pump unit is shut down the medium remains in thecylindrical gap so that a re-start,even after an extended shut down period is assured.Wear at the high pressure seal components does not lead to an abrupt breakdown of the pump but rather a gradual decrease in the flow rate. If the pump is driven in a control loop the r.p.m. of the driver will increase in direct proportion to component wear.S p e e dThe running speed of the pump is a direct indicator of the extent of wear.This enables long term planning of maintenance intervals and targeting ofspecific servicing tasks.We manufacture extremely compact Triplex and Quintuplex pump units for injection of Methanol, LDHI,Glycol and a range of inhibitors.Hammelmann high pressure pump units in the pressure range up to 15,000 psi (1035 bar) havedeveloped into the standard choice for offshore methanol injection applications with a reputation for extreme reliability and minimal maintenance requirements.Compact constructionExtensiveperformancerangeWith both Triplex andQuintuplex pumpsavailable we cansupply a veryextensive range offlow rates andoperating pressures.Power ratingsup to 1000 HPup to 750 kWFlow ratesup to 530 gpmup to 2000 l/minOperating pressuresup to 55,000 psiup to 3800 barHammelmann pumps producemaximum performance from aminimal footprint which is the resultof combining a compact integralspeed reduction gear end with theconcept of a vertical configuration.The vertical configuration channelsoscillating forces directlydownwards into the base structure.Unwanted lateral oscillations asproduced by horizontal pumps donot occur.The integral speed reducer with twinhelical gears arranged in a herringbone configuration ensures smoothrunning and even powertransmission without axially loadingthe bearings.A selection of gear ratios isavailable to allow the optimal choiceof driver. The compact constructioneliminates the need for an externalgear box and prevents rotaryoscillation.

极压润滑是在金属塑性加工过程中,为防止金属在边界摩擦条件和高温下产生的微凸体粘着现象,利用极压润滑剂生成的化学反应膜所进行的润滑。
极压润滑时,生成的化学反应膜是一层较厚的无机盐膜,在负荷和速度比较极端的情况下,具有良好的润滑效果。
但是,当温度升高至一定值时,化学反应膜存在破坏或解吸的可能性,这取决于EP添加剂和金属表面的成分组成。
由于自身形成需要一定时间,而工件变形时间较短,以致许多金属塑性加工过程中,化学反应膜可能在工模具表面而不是在工件表面生成。
目前,应用和研究的极压添加剂可分为含硫、磷和氯极压添加剂,有机金属盐类,硼酸盐类和稀土类极压抗磨剂,另外,杂环类和纳米粒子也可用于极压抗磨剂。
含硫极压添加剂常用的含硫极压添加剂主要有硫磷酸含氮衍生物、硫磷酸钼、硫化动物油、硫化烯烃、多硫化物等,其中,用的最广泛的是硫化烯烃。
这类添加剂主要表现出较强的抗烧结能力和良好的耐负荷性能,与其他类型的添加剂具有优良的复配效应。
研究表明,C-S键打开的难易程度决定其极压性,S-S键决定其抗磨性。
一般来讲,抗磨性随链长度的增长而增强,初始咬人负荷和烧结负荷随硫原子个数的增多而明显增加。
在边界润滑条件下,含硫极压抗磨剂与摩擦表面发生摩擦吸附和化学反应,生成含硫的无机膜或在有氧化铁的存在下形成0。
15mm以上的Fe203—FeS的极压化学反应膜,从而起到抗擦伤和抗烧结作用,其水解稳定性好,熔点高,在800℃的高温仍然有效。
含磷极压添加剂国内外常用的含磷极压添加剂主要有酸性亚磷酸二丁酯、磷酸三甲酚酯、硫代磷酸酯、磷酸酯和酸性磷酸酯胺盐,其中,用得最多的是有机磷酸酯。
含磷极压添加剂品种繁多,按所含有效活性元素划分,可分为磷型、磷氮型和硫磷氮型,对其作用机理研究最多的是磷型添加剂。
目前,普遍认为,在摩擦条件下,磷系添加剂在摩擦表面形成了有机磷酸盐化学反应膜,从而具有良好的抗磨性能。
磷—氮型添加剂中,氮元素不仅具有抑制磷元素过度腐蚀的作用,而且具有使吸附分子间横向引力增强,油膜强度增强的功能,有利于抗磨性的改善。

压裂液作为压裂改造储层中的关键流体,其优异的黏弹性和耐温性,对造缝、携砂形成油气疏通的油气缝网尤为重要[1]。
目前,压裂液以胍胶、清洁压裂液和聚合物压裂液为主。
其中胍胶价格昂贵,破胶残渣较多,容易造成地层伤害。
清洁压裂液虽具有破胶残渣少的特点,但其不仅价格昂贵,且耐温性较差,无法大规模使用。
近年来,聚合物压裂液价格低廉,携砂性好,摩阻低,低伤害及破胶残渣少等优点,受到了压裂工作者的广泛青睐[2]。
超分子乳液压裂液[3],作为一种新型聚合物压裂液体系,通过乳液稠化剂与自制增效剂复配,实现分子间自组装相互穿插,使阴阳离子间相互吸引形成离子键,并通过分子间氢键和分子间相互作用力,使得压裂液网络结构更加复杂实现增黏。
同时,该网状结构高温剪切破坏后能够重新复原,因此在整个压裂施工中,液体黏度变化不大。
结果表明:由于体系分子间氢键、离子键和分子间相互作用力协同作用,同用量下比普通聚合物压裂液表现出更优异的耐温耐剪切性和黏弹性。
