A10VSO液压泵简介( 变量调节过程)

力士乐A10VSO系列柱塞泵安装说明书安全说明在调试和运行过程中，力士乐A10VSO系列轴向柱塞单元必须始终充满液压油并排放空气。

在停用时间相对较长时，也应遵守上述注意事项，因为力士乐A10VSO系列轴向柱塞单元通过液压管路排空。

尤其对于“传动轴朝上”或“传动轴朝下”的安装位置，必须注意完全地充满和放气，否则会造成风险 (例如空运转)。

马达外壳内的壳体泄油必须通过最高壳体泄油口 (L1、L2、L3)排放到油箱。

对于多个设备的组合，应确保不超过每个设备的相应壳体压力。

当力士乐A10VSO系列轴向柱塞单元设备的壳体泄油口存在压差时，必须更换共用的壳体泄油管路，以使在任何情况下，都不超过所有连接设备的最小允许壳体压力。

如果无法做到这点，必要时应铺设单独的壳体泄油管路。

为了获得有利的噪音值，应使用弹性元件分离所有连接管路，并避免在油箱上方安装。

在所有工况下，吸油管路和壳体泄油管路必须通入油箱中最低油位以下的位置。

允许吸油高度 hS 取决于总压力损失，但不会高于其最大值 (hS max = 800 mm)。

在运转期间，油口 S的最小吸油压力还不得降至 0.8 bar 绝对压力以下。

安装位置请参见以下示例 1 至 12。

其他安装位置可应要求提供。

建议的安装位置：1 和 3。

力士乐A10VSO系列轴向柱塞单元在油箱下方安装 (标准)在油箱下方安装意味着力士乐A10VSO系列轴向柱塞单元安装在油箱外部，低于最低油位。

具体安装图请见下面的描述：力士乐A10VSO系列轴向柱塞单元在油箱上方安装在油箱上方安装意味着力士乐A10VSO系列轴向柱塞单元安装在油箱的最低油位上方。

为了防止力士乐A10VSO系列轴向柱塞单元排空，在安装位置6 的油口 L1，至少需要 25 mm 的高度差 hES min。

遵守最大允许吸油高度 hS max = 800 mm 的要求。

壳体泄油管路中的单向阀仅允许在个别情况下使用。

该柱塞泵属于斜盘变量柱塞泵，流量正比于驱动转速和排量，并通过调节斜盘倾角实现无级变量。

除了压力控制功能外，借组于负载（如小孔）压差，可以改变泵的流量。

泵仅提供执行机构的实际流量。

图1 A10VSO-DFR1原理图1 工作原理负载敏感DFR的原理，DFR分两个部分，一个是压力控制DR，一个是流量控制FR。

DR恒压控制，即通过阀控变量油缸来保证出口压力基本不变，就是压力控制阀（原理图下面的三通阀）控制变量油缸，出口压力在稳态时与压力控制阀右端的可调弹簧力相平衡，变量泵的变量压力PP通过调节压力阀的弹簧设定，当系统压力没有达到调定的恒压压力时，泵排出最大流量，相当于一个定量泵。

当系统压力达到所调的恒压压力时，泵进入恒压工况，负载的速度进入可调阶段。

速度进入可调阶段，流量即发生变化，该变化是系统要求泵输出的流量要有所变化的。

例如开始阶段油缸是快速动作，泵提供最大流量例如150L/min，下一个阶段系统只要求50L/min的流量就够了，这个时候，泵输出流量相当于负载的速度要求要大，如果泵不改变输出的150L/min流量，就会出现供（150）过于求（50），根据压力流量基本公式，系统压力就会升高，在节流阀上的压力损失将增加，压力阀的弹簧被压缩，阀芯右移，泵主动变量缸推动斜盘使角度减小，输出流量相对减小，直到泵打出去的流量正好是50L/min，系统压力恢复到设定值，下面这个恒压控制阀就回到中位初始位置，泵稳定在输出50L/min的斜盘位置上。

A10VSO DFR原理
A10VSODFR1用途广泛，并可让我们理解负荷传感之应用，值得和大家分享，但手上只有英文说明，无论如何，总比没有好。

1. 起始状态：节流阀关闭，负荷为O，油泵以底压变为O排量。

底压不能变为O，否则压力不足以油泵变量。

2. 节流阀开口度增大：节流阀开口度增大瞬问，压差下降，泵上之流量控制阀打开通住加大流量之控制活塞，流量加大；流量加大，压差加大，泵上之流量控制阀重新找到平衡点，流量不再加大。

3. 节流阀开口度减少：类似第2点；
4. 先导压力控制：
5. 最高限压：。

If necessary please contact our technical department (please indicate type of the hydraulic fluid used in your application when ordering.Operating viscosity rangeWe recommend that the operating viscosity (at operating temperature) for both the efficiency and life of the unit, be chosen within the optimum range ofνopt = opt. operating viscosity 80...170 SUS (16...36 mm 2/s)referred to tank temperature at open circuit.Viscosity limitsThe limiting values for viscosity are as follows:νmin =60 SUS (10 mm 2/s)short term (t ≤ 1 min)at a max. permissible leakage oil temperature of t max = 195 °F (90 °C).Please note that the max. fluid temperature of 195 °F (90 °C) is also not exceeded in certain areas (for instance bearing area).The temperature in the bearing area is approx. 7 °F (5 K )higher than the average leakage fluid temperature.νmax =7500 SUS (1600 mm 2/s)short term (t ≤ 1min)on cold start(p ≤ 435 psi/30 bar, n ≤ 1000 rpm, t min = -13 °F/-25 °C)Notes on the selection of hydraulic fluidIn order to select the correct fluid, it is necessary to know the operating temperature in the tank (open circuit) in relation to the ambient temperature.The hydraulic fluid should be selected so that within the operating temperature range, the viscosity is within the op-timum range (νopt.; see shaded section of the selection dia-gram). We recommend that the higher viscosity grade is selected in each case.Example: at an ambient temperature of X °F (°C) the operating temperature in the tank is 140 °F (60 °C). In the optimum vis-cosity range νopt ( shaded area), this corresponds to viscosity grades VG 46 or VG 68, VG 68 should be selected.Important: The leakage oil temperature is influenced by pressure and speed and is typically higher than the tank temperature. However max. temperature at any point in the system may not exceed 195 °F (90 °C).At high temperatures please use FKM seals.If the above mentioned conditions cannot be kept due to ex-treme operating parameters or high ambient temperatures,please consult us.Filtration of fluidThe finer the filtration, the better the achieved cleanliness of the fluid and the longer the life of the axial piston unit.To ensure a reliable functioning of the axial piston unit, a mini-mum cleanliness of20/18/15 acc. to ISO 44061) is necessary.If the above cleanliness classes cannot be met please consult us.1)draft issue 1999Selection diagramRA 92 711/10.07 | (A)A10VSOIndustrial Hydraulics | Bosch Rexroth AG 5/361,21,11,00,90,70,80,91,4 201,2 17.51,0 14.50,9 130,8 11.51,01,6 23I n p u t p r e s s u r e p a b Displacement V g / V gmaxbar psiS p e e d n /n m a xTechnical dataInlet operating pressure rangeAbsolute pressure at port Sp abs min _____________________________________________________________12 psi (0,8 bar)p abs max__________________________________________________________435 psi (30 bar)Output operating pressure rangePressure at port BNominal pressure p N _________________________________4000 psi (280 bar)Peak pressure p max _____________________________________5100 psi (350 bar)(Pressure data to DIN 24312)Limitation of pump output pressure spikes is possible with relief valve blocks mounted directly on flange connection, acc. to data sheets RA 25 880 and RE 25 890 to be ordered separately.Direction of flowS to B.Case drain pressureThe max. permissible pressure of the leakage fluid (at port L, L 1)max. 7 psi (0,5 bar) higher than inlet pressure at port S, but not higher than 29 psi (2 bar) absolute.p L abs max _____________________________________________________________29 psi (2 bar)Maximum permissible speed (Speed limit)Graph, showing permissible speed with increased inlet pres-sure at port S ( pw abs ) resp. reduced displacement(V g < V g max ).High speed versionThe size 71...140 is available in an optional high speed version.This version allows higher drive speeds at max. displacement (higher output flow) without affecting outside dimensions, see table on page 6.Important: The drive speed increase (1.2 • n 0) refers to the standard drive speed n 0.e.g. size 100:n max = 1.2 • 2000 rpm = 2400 rpmWRONG : 1.2 • 2400 rpm = 2880 rpmMechanical displacement limiterMechanical displacement limiter is standard on the non-through drive model N00, but not possible for the model with through drive.Exception: With DFE1 control a max. displacement screw is not possible at all.V g max :for sizes 18 to 140Setting range from 50 % to V g max stepless V g min :for sizes 100 to 140Setting range from zero to 50 % of V g max stepless6/36Bosch Rexroth AG | Industrial Hydraulics (A)A10VSO | RA 92 711/10.07Table of valuesDetermination of sizeFlowq v =[gpm]q v =[L/min]Torque T =[lb-ft]T =[Nm]Power P =[HP]P =[kW]V g • n • ηv 1000V g • ∆ p 20 • π • ηmh q v • ∆ p V g =Displacement per revolution in in 3 (cm 3)∆ p =Differential pressure in psi (bar)n=Speed in rpm (min –1)ηv =Volumetric efficiencyηmh =Mechanical-hydraulic efficiency ηt =Total efficiency600 • ηtV g • n • ηv 23124 • π • ηmh q v • ∆ p 1714 • ηtV g • ∆ p ((()))Technical Data1)These values are valid for an absolute pressure of 14.5 psi (1 bar) at the suction port S.

力士乐柱塞泵的使用与维修工作单位：潍柴铸锻公司老厂区三车间姓名：王建光指导老师：日期：2012年9月13日力士乐柱塞泵的使用与维修摘要：本文主要介绍了力士乐A10VSO型号的柱塞泵在意大利FA造型线液压系统中的使用，以及在日常维护中出现的相关问题，并对问题进行解决。

关键词：柱塞泵压力控制流量控制开式回路FA气冲造型线是由意大利FA公司制造，具有国际先进水平的铸造生产线，该线自动化水平高，运行平稳，其液压系统主要采用德国BOSCH-REXROTH公司的产品，系统工作压力为12MPA，主机辅助压实压力为17MPA，由于生产线不少动作是由变频减速机通过齿轮齿条传动来取代液压缸和液压马达，液压控制部分较少，故全线采用4台力士乐AV10系列高压柱塞泵集中供油，以保证生产线的工作压力。

力士乐A10VSO柱塞泵外形图1-0压力与流量调节阀出油口泄露油口图1-0力士乐轴向柱塞泵内部结构复杂，因其活塞或柱塞的往复运动方向与缸体中心轴平行，所以称为轴向柱塞泵。

轴向柱塞泵是利用与传动轴平行的柱塞在柱塞孔内往复运动所产生的容积变化来进行工作的。

由于柱塞和柱塞孔都是圆形零件，加工时可以达到很高的精度配合，因此容积效率高，运转平稳，流量均匀性好，噪声低，工作压力高等优点，但对液压油的污染较敏感，结构较复杂，造价较高。

力士乐A10VSO柱塞泵如图1-1所示：图1-1此型号柱塞泵主要由主轴，壳体，配流盘，转子，斜盘，柱塞以及变量机构组成，该泵的主要特点是：用于开式液压回路，流量正比与驱动转速和排量，并能通过调节斜盘倾角实现无级变量，具有优良的吸油特性，低噪音，高寿命。

在日常的设备维修过程中，通过拆卸分解轴向柱塞泵，可检查泵的下列方面：●配流盘是否磨损、拉槽。

柱塞与缸孔之间的间隙是否过大。

这些磨损与压力、流量下降，泄漏油管内泄漏增大等症状有关。

●中心弹簧是否疲软或折断，它与压力、流量下降有关。

●柱塞阻尼孔是否阻塞，它与滑靴干摩擦时泵在运行中发出尖叫声有关。

该液压泵站的主泵采用的是一个带流量限制器的力士乐A10VSO恒压变量泵。

力士乐A10VSO变量泵实际是在恒压变量泵的基础上加装一个流量限制器(用后缀S0169表示)。

泵的标牌上标有“DR”(即恒压)字样。

从其性能曲线上看确与通常所说的恒压变量的定义不相符。

该泵的两个输出压力和高压所对应的流量应如何调整呢?1、首先，将溢流阀的压力调节螺钉调至最松状态，最小流量限制器调至最小状态(上部的液压缸调节螺钉调至最松状态)，流量控制阀调节螺钉调至最紧状态，并在溢流阀后串接一流量计；2、启动液压泵，调节最小流量限制器上部的液压缸调节螺钉，使流量计的读数为Q2；3、再缓慢旋紧溢流阀的压力调节螺钉，使压力表的读数为80bar；4、此时，再缓慢旋松流量控制阀调节螺钉，直至流量计的读数不再变小；5、接着，再缓慢旋紧溢流阀的压力调节螺钉，使压力表的读数为260bar；6、最后，调节最小流量限制器下部的液压缸调节螺钉，使流量计的读数为Q1，至此调节完毕。

扩展资料：恒压变量泵调压带安全阀：1、恒压泵要调节其设定压力值；2、如果泵出口有系统安全阀的话，安全阀所调压力要高于恒压泵调定压力，高多少要看系统情况，一般例如1MPa或略大；千万不能小于恒压泵调定压力，否则恒压泵进不了恒压工况。

这一点以往的教科书可能强调不够，如前面所说，恒压泵在未达到调定压力之前，实际上是起到最大排量的定量泵作用。

3、系统选用恒压泵的出发点，就是基于低压大流量，实现快进；下一步实现高压小流量，既保压又没有多余流量溢流而发热。

4、恒压泵进入恒压工况（达到其调定压力）后，它能根据系统的需要提供最大流量以下的流量，系统要多就多提供，系统要少就少提供，而保持系统为恒压压力。

像保压这种系统不需要流量时，泵的流量只要满足内泄漏就行了。

5、现在有好几家的样本，将变量泵的压力切断动能与恒压功能等同起来，实在是误解，因为压力切断功能是一旦达到设定切断压力，泵的输出流量很快就讲到零。
