PGH4-30/040RE11VE4 PGH齿轮泵
齿轮泵按齿轮啮合形式分:
(l)外啮合式;(2)内啮合式。
外啮合齿轮泵的优点是结构简单、尺寸小、重量轻、制造维护方便、价格低廉、工作可靠、自吸能力强、对油液污染不敏感等。它的不足是齿轮承受不平衡的径向液压力,轴承磨损严重,泄漏量大。工作压力的提高受到径向液压力和容积效率的限制;流量脉动大,噪声高。
内啮合齿轮泵结构紧凑、尺寸小、重量轻。由于齿轮同向旋转,齿面相对滑动速度小、磨损轻微、使用寿命长、流量脉动远比外啮合齿轮泵小,因而噪声比较小。内啮合齿轮泵允许使用较高的转速,可获得较高的容积效率。但是内啮合齿轮泵同样存在着径向液压力不平衡的问题,限制了其工作压力的进一步提高。另外,齿轮泵的排量不可调节,在一定程度上限制了其使用的范
困油现象
原因:液压油在渐开线齿轮泵运转过程中,因齿轮相交处的封闭体积随时间改变,常有一部分的液压油被密封在齿间,如图所示,称为困油现象,因液压油不可压缩将使外接齿轮产生较大的振动和噪声,影响系统正常工作。
措施:在前后盖板或浮动轴套上开卸荷槽,开设卸荷槽的原则:两槽间距为较小闭死容积,而使闭死容积由大变小时与压油腔相通,闭死容积由小变大时与吸油腔相通。
泄漏现象
齿轮泵的泄漏,外啮合齿轮运转时泄漏途径有以下三点:一为齿轮顶隙,其次为测隙,第三为啮合间隙。
其中端面侧隙泄漏,占总泄漏量的80%-85%,当压力增加时,前者不会改变,但后者挠度大增,此为外啮合齿轮泵泄漏较主要的原因,容积效率较低,故不适合用作高压泵。
解决方法:端面间隙补偿采用静压平衡措施,在齿轮和盖板之间增加一个补偿零件,如浮动轴套、浮动侧板。
搅拌车液压泵压力不足的原因、诊断和排除方法
(1)搅拌车液压泵是否能输出油液压油。
若无液压油输出,则可能是泵的转向不对,零件磨损严重或损坏;吸油管阻力过大(滤油器阻塞、油液黏度过大等)或漏气。如果是新的液压泵,可能是泵体有铸造缺陷(缩孔、砂眼等),使吸油腔和压油腔相通,失去压油能力,输入功率不足,使泵的输油压力达不到工作压力,泵轴扭断,而输不出油
若液压泵有油液输出,则应检查各回油管,观察哪个部件溢由。如溢流阀回油管溢油,可能是调定压力低。此时,拧紧易诱发调压弹簧,若压力无变化,则可能是溢流阀主阀芯或先导部分的锥因脏物或锈蚀而卡死在开口位置;或因弹簧折断失去作用;或因阻尼孔被脏物阻塞,泵输出的油液立即经溢流阀流回油箱。排除方法:应拆开溢流阀,加以清洗。检查或更换弹簧,恢复其工作性能
(2)溢流阀工作是否正常。
若不正常,则可能是压力油路中的某个阀有污物或其它原因卡住,处于回油位置,致使压力油路与溢流回路短路,也可能是管接头松脱,或处于压力油路中的某些阀泄漏严重,或液压缸、液压马达的密封损坏,严重泄漏。排除方法:拆开有关阀进行清洗,检查密封尖刺的发小及各种,密封装置,密封装置损坏应更换
(3)若整个搅拌车液压系统能建立正常压力,而某些管路或液压缸(或液压马达)中无压力,则可能是由于管路、小孔或节流阀、换向阀等部位堵塞。此时,应铸段检查压力和有无油液通过,找出原因,加以排除
(4)若液压泵输出流量随压力升高而显著减小,且压力大达不到规定值,则是由于液压泵磨损后间隙所致。排除方法:测定液压泵的容积效率,即可确定该泵是否能继续使用,对磨损严重的零件,应进行修配或更换

提高齿轮油泵性能的可行回路
齿轮油泵因受定排量的结构限制,通常认为齿轮泵仅能作恒流量液压源使用。
在泵上直接安装控制阀,可省去泵与方向阀之间管路,从而控制了成本。较少管件及连接件可减少泄漏,从而提高工作可靠性。而且泵本身安装阀可降低回路的循环压力,提高其工作性能。下面是一些可提高齿轮泵基本功能的回路,其中有些是实践证明可行的基本回路,而有些则属创新研究。
卸载回路
卸载元件将在大流量泵与小功率单泵结合起来。液体从两个齿轮油泵因受定排量的结构限制,通常认为齿轮泵仅能作恒流量液压源使用.齿轮油泵因受定排量的结构限制,通常认为齿轮油泵仅能作恒流量液压源使用。然而,附件及螺纹联接组合阀方案对于提高其功能、降低系统成本及提高系统可靠性是有效的,因而,齿轮油泵的性能可接近价昂、复杂的柱塞泵。的性能可接近价昂、复杂的柱塞泵。的出口排出,直至达到预定压力和(或)流量。这时,大流量泵便把流量从其出口循环到入口,从而减少了该泵对系统的输出流量,即将泵的功率减少至略高于高压部分工作的所需值。流量降低的百分比取决于此时未卸载排量占总排量的比率。组合或螺纹联接卸载阀减少乃至消除了管路、孔道和辅件及其它可能的泄漏。
