工業(yè)設(shè)備：冶金、采礦 化工、塑料、壓鑄機(jī)械、

船舶機(jī)械、起重機(jī)、陶瓷機(jī)械、鋁材機(jī)等的液壓主泵、輔泵、馬達(dá)。

船舶/：舵船舶機(jī)、錨機(jī)、起重機(jī)等應(yīng)用于船艦/艦艇上的甲板機(jī)械、操作及控制的船舶液壓技術(shù)行業(yè)用泵&馬達(dá);液壓技術(shù)行業(yè)用泵/馬達(dá)及附屬裝置。

液壓泵過(guò)度發(fā)熱有兩個(gè)原因：一是機(jī)械摩擦生熱。柱塞泵由于運(yùn)動(dòng)表面處于干摩擦

或半干摩擦狀態(tài)，運(yùn)動(dòng)部件相互摩擦生熱。二是液體摩擦生熱。高壓油通過(guò)各種縫隙泄漏到低壓腔，大量的液壓能損失轉(zhuǎn)為熱能；長(zhǎng)期負(fù)荷過(guò)大導(dǎo)致卸荷閥頻繁開(kāi)啟，油缸或閥有內(nèi)泄（閥內(nèi)部磨損，缸密封不好）；閥或管道有堵塞現(xiàn)象。所以正確選擇運(yùn)動(dòng)部件之間的間隙、油箱容積和冷卻器，可以杜絕泵的過(guò)度發(fā)熱和油溫過(guò)高的現(xiàn)象。另外，回油過(guò)濾器堵塞造成回油背壓過(guò)高，也會(huì)引起油溫過(guò)高和泵體過(guò)熱。 

液壓泵轉(zhuǎn)速高，排油壓力高，工作環(huán)境惡劣，油液污染、油液選用不合規(guī)定或油液過(guò)少，都可造成泵損、泄漏。泵內(nèi)泄漏可使其功率損失加大，磨損嚴(yán)重。油液中侵入空氣后易于壓縮，可造成泵干磨。液壓泵內(nèi)長(zhǎng)時(shí)間的泄漏、干磨或壓縮厲害， 必然發(fā)熱，引起油液升溫，造成系統(tǒng)發(fā)熱。 

變量液壓泵的伺服變量機(jī)構(gòu)損壞也會(huì)造成系統(tǒng)發(fā)熱，工作元件無(wú)力，或是系統(tǒng)過(guò)載,導(dǎo)致發(fā)動(dòng)機(jī)、電動(dòng)機(jī)悶車(chē)甚至停止工作 

伺服變量機(jī)構(gòu)損壞，假如不能變量了，必然導(dǎo)致系統(tǒng)高壓溢流，長(zhǎng)期從而導(dǎo)致發(fā)熱！伺服變量機(jī)構(gòu)損壞有兩種表現(xiàn)：不變量，過(guò)早變量。不變量導(dǎo)致系統(tǒng)過(guò)載，因?yàn)榇藭r(shí)變量泵相當(dāng)于定量泵。此時(shí)功率和壓力成正比；過(guò)早變量，相同的壓力時(shí)，系統(tǒng)流量變小，顯得工作元件無(wú)力，系統(tǒng)工作速度變慢。假如伺服閥不能換向了那么液壓泵就只能始終在較大排量下工作，

自然會(huì)發(fā)熱。定量泵 溢流閥。

A10VG45EP4D1/10R-NTC10F023ST-S力士樂(lè)柱塞泵柱塞泵的泵油機(jī)構(gòu)包括兩套準(zhǔn)確偶件：柱塞（plunger） 柱塞套(barrel)構(gòu)成柱塞偶件(plunger and barrel assembly)（圖5-11）、出油閥（delivery valve）和出油閥座(delivery valve seat)構(gòu)成出油閥偶件(delivery valve assembly

柱塞和柱塞套是一對(duì)準(zhǔn)確偶件，經(jīng)配對(duì)研磨后不能互換，要求有高的精度和光潔度和好的耐磨性，其徑向間隙為0.002～0.003mm

柱塞頭部圓柱面上切有斜槽，并通過(guò)徑向孔、軸向孔與頂部相通，其目的是改變循環(huán)供油量；柱塞套上制有進(jìn)、回油孔，均與泵上體內(nèi)低壓油腔相通，柱塞套裝入泵上體后，應(yīng)用定位螺釘定位。
