Rexroth壓力繼電器一般由鐵芯、線圈、銜鐵、觸點(diǎn)簧片等組成的。只要在線圈兩端加上一定的電壓，線圈中就會(huì)流過一定的電流，從而產(chǎn)生電磁效應(yīng)，銜鐵就會(huì)在電磁力吸引的作用下克服返回彈簧的拉力吸向鐵芯，從而帶動(dòng)銜鐵的動(dòng)觸點(diǎn)與靜觸點(diǎn)（常開觸點(diǎn)）吸合。當(dāng)線圈斷電后，電磁的吸力也隨之消失，銜鐵就會(huì)在彈簧的反作用力返回原來的位置，使動(dòng)觸點(diǎn)與原來的靜觸點(diǎn)（常閉觸點(diǎn)）吸合。這樣吸合、釋放，從而達(dá)到了在電路中的導(dǎo)通、切斷的目的。對(duì)于繼電器的"常開、常閉"觸點(diǎn)，可以這樣來區(qū)分：繼電器線圈未通電時(shí)處于斷開狀態(tài)的靜觸點(diǎn)，稱為"常開觸點(diǎn)"；處于接通狀態(tài)的靜觸點(diǎn)稱為"常閉觸點(diǎn)"。
壓力繼電器有直動(dòng)型和先導(dǎo)型;也有帶延時(shí)調(diào)節(jié)和不帶延時(shí)調(diào)節(jié)的; 也有彈簧調(diào)節(jié)型和開關(guān)位置調(diào)節(jié)型。各種壓力繼電器盡管類型不同,原理只有一個(gè),即靠液體壓力與彈簧力的平衡,使柱塞或杠桿產(chǎn)生一定的位移,將電氣開關(guān)接通與斷開。壓力繼電器的任務(wù)是把系統(tǒng)某 較穩(wěn)定的壓力信號(hào)反映出去, 以控制其它的順序動(dòng)作,但它由于自身和外界的原因,有可能發(fā)出誤信號(hào),影響液壓系統(tǒng)的工作可靠性和安全性。
產(chǎn)品作用：
如果要監(jiān)測(cè)的壓力低于調(diào)定壓力,則操作微動(dòng)開關(guān)。要監(jiān)測(cè)的壓力通過節(jié)流孔(7)傳到柱塞(2)。柱塞(2)受彈簧座(6)支持并克服壓縮彈
簧(3)不斷變化的作用力。彈簧座將柱塞(2)的運(yùn)動(dòng)傳輸?shù)轿?dòng)開關(guān)(5) ,并在達(dá)到調(diào)定壓力時(shí)釋放后者的壓力。這會(huì)打開或關(guān)閉電路,具體
取決于電路設(shè)置。彈簧座(6)的機(jī)械前擋塊在壓力突然降低和過壓的情況下,可保護(hù)微動(dòng)開關(guān)(5)兔于受到機(jī)械損傷,并防止壓縮彈簧(3)的
固態(tài)壓縮。
