LC25DR40E7X插裝式減壓閥

性能

(1)調(diào)壓范圍：它是指減壓閥輸出壓力P2的可調(diào)范圍，在此范圍內(nèi)要求達(dá)到規(guī)定的精度。調(diào)壓范圍主要與調(diào)壓彈簧的剛度有關(guān)。

(2)壓力特性：它是指流量g為定值時(shí)，因輸入壓力波動(dòng)而引起輸出壓力波動(dòng)的特性。輸出壓力波動(dòng)越小，減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。

(3)流量特性：它是指輸入壓力—定時(shí)，輸出壓力隨輸出流量g的變化而變化的持性。當(dāng)流量g發(fā)生變化時(shí)，輸出壓力的變化越小越好。一般輸出壓力越低，它隨輸出流量的變化波動(dòng)就越小

減壓閥是通過調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。

二通插裝閥以其獨(dú)特的優(yōu)點(diǎn)以及經(jīng)濟(jì)和技術(shù)上的明顯優(yōu)勢(shì)被廣泛應(yīng)用到各個(gè)行業(yè)。在集成的液壓元件中，當(dāng)通徑小于32mm時(shí)，可采用疊加

閥，當(dāng)通徑大于中32mm時(shí)，應(yīng)考慮采用插裝閥。在一個(gè)液壓系統(tǒng)中,可根據(jù)需要，液壓控制閥全部采用二通插裝閥;也可以部分液壓控制閥采用滑閥式，另一部分液壓控制閥采用二通插裝閥，充分發(fā)揮兩種液壓控制閥各自的優(yōu)點(diǎn)。

壓力機(jī)械屬于重型機(jī)械，主要應(yīng)用于冶金行業(yè).重型機(jī)械制造、化工等行業(yè)，如沖壓機(jī)、鍛造機(jī)、剪切機(jī)、粉末制品壓力機(jī)、擠壓機(jī)等。壓力機(jī)械的動(dòng)力及控制部分多數(shù)采用液壓傳動(dòng),由于液壓系統(tǒng)所需的壓力高、流量大，故適于用二通插裝閥來(lái)控制液壓系統(tǒng)的壓力、流量和流動(dòng)方向。

挖掘機(jī)是工程機(jī)械主力機(jī)種，是建設(shè)工程的主要生產(chǎn)工具，因此對(duì)挖掘機(jī)提出了很高的要求。要求節(jié)能低排放、**率、良好的操縱性和降低對(duì)環(huán)境的負(fù)荷等，要實(shí)現(xiàn)這些要求必須對(duì)挖掘機(jī)進(jìn)行控制，由于液壓控制信息處理能力差，不能光靠液壓控制主要要靠電子控制。液壓動(dòng)力由液壓泵提供，要知道液壓泵是挖掘機(jī)液壓系統(tǒng)的能源裝置，將電機(jī)的機(jī)械能轉(zhuǎn)換為液壓能，輸出流量和壓力，在液壓系統(tǒng)中占有非常重要的地位。如果液壓泵出現(xiàn)故障，將會(huì)影響到整個(gè)液壓系統(tǒng)的正常工作。
