rexroth力士樂機(jī)械壓力開關(guān)HED 5 OH-3X/100K14V R901227565結(jié)構(gòu)特點(diǎn)

基本組成結(jié)構(gòu)

閥體與插件:由閥體、帶閥芯的插件、彈簧、調(diào)節(jié)元件和微型開關(guān)構(gòu)成核心結(jié)構(gòu)。液壓油通過阻尼孔作用于閥芯,閥芯右端由彈簧座支撐,通過彈簧力與壓力平衡實(shí)現(xiàn)動(dòng)作觸發(fā)。

壓力傳遞機(jī)制:當(dāng)系統(tǒng)壓力達(dá)到設(shè)定值時(shí),彈簧座將柱塞運(yùn)動(dòng)傳遞至微動(dòng)開關(guān),驅(qū)動(dòng)電路接通或斷開,完成壓力信號(hào)到電氣信號(hào)的轉(zhuǎn)換。

安裝與連接設(shè)計(jì)

板式與管式兼容性:支持板式安裝和管式連接,滿足多樣化安裝場(chǎng)景需求。

多向安裝適配:依據(jù)DIN 24340 J4標(biāo)準(zhǔn)設(shè)計(jì),可垂直或水平安裝,提升設(shè)備布局靈活性。

電氣接口標(biāo)準(zhǔn)化:配備4針M12插頭連接電纜,防護(hù)等級(jí)達(dá)IP65(符合DIN EN 60529),確保惡劣環(huán)境下的可靠連接。

壓力調(diào)節(jié)與量程特性

多級(jí)壓力調(diào)節(jié):提供5個(gè)壓力等級(jí),通過帶內(nèi)六角的心軸、帶刻度旋鈕等調(diào)節(jié)元件實(shí)現(xiàn)精準(zhǔn)設(shè)定,調(diào)節(jié)范圍覆蓋差動(dòng)與非差動(dòng)壓力類型。

寬量程覆蓋:壓力范圍達(dá)350 bar(5,076.32 psi),適用于液壓系統(tǒng)的高壓監(jiān)測(cè)場(chǎng)景。

觸點(diǎn)與電氣性能

雙觸點(diǎn)功能:集成常開(NO)和常閉(NF)觸點(diǎn),支持電流1 mA至2 A的無電位切換,滿足不同電路控制需求。

高精度與穩(wěn)定性:轉(zhuǎn)換精確度為調(diào)定壓力的±1%,重復(fù)精度高,長期漂移控制在合理范圍內(nèi),確保長期使用的可靠性。

環(huán)境適應(yīng)性設(shè)計(jì)

耐溫范圍廣:工作溫度范圍-40°C至+122°C。

材料耐腐蝕性:與介質(zhì)接觸部件采用不銹鋼、陶瓷或FKM(氟橡膠)制造,兼容液壓油等工業(yè)流體,延長使用壽命。

安全與認(rèn)證標(biāo)準(zhǔn)

多重安全認(rèn)證:通過UL認(rèn)證和CCC認(rèn)證(MT版除外),符合EN 61058-1:1993、IEC 60947-5-1等國際標(biāo)準(zhǔn),確保設(shè)備安全合規(guī)。

防護(hù)等級(jí)強(qiáng)化:IP65防護(hù)等級(jí)可有效防止灰塵和低壓水柱侵入,保障電氣部分穩(wěn)定運(yùn)行。
