力士樂(lè)溢流閥的作用 力士樂(lè)溢流閥定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí)，會(huì)使流量需求減小。此時(shí)溢流閥開(kāi)啟，使多余流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動(dòng)開(kāi)啟）。 力士樂(lè)溢流閥穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥產(chǎn)生背壓，運(yùn)動(dòng)部件平穩(wěn)性增加。系統(tǒng)卸荷作用：在溢流閥的遙控口串接溢小流量的電磁閥，當(dāng)電磁鐵通電時(shí)，溢流閥的遙控口通油箱，此時(shí)液壓泵卸荷。溢流閥此時(shí)作為卸荷閥使用。 力士樂(lè)溢流閥安全保護(hù)作用：系統(tǒng)正常工作時(shí)，閥門(mén)關(guān)閉。只有負(fù)載超過(guò)規(guī)定的極限（系統(tǒng)壓力超過(guò)調(diào)定壓力）時(shí)開(kāi)啟溢流，進(jìn)行過(guò)載保護(hù)，使系統(tǒng)壓力不再增加（通常使溢流閥的調(diào)定壓力比系統(tǒng)zui高工作壓力高10%～20%）。 實(shí)際應(yīng)用中一般有：作卸荷閥用，作遠(yuǎn)程調(diào)壓閥，作高低壓多級(jí)控制閥，作順序閥，用于產(chǎn)生背壓（串在回油路上）。溢流閥一般有兩種結(jié)構(gòu)：1、直動(dòng)型溢流閥 。2、先導(dǎo)式溢流閥。對(duì)溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動(dòng)作靈敏，過(guò)載能力大，噪聲小。 Z2FS10-5-3X/V Z2FS10-5-3X/ Z2FS10-5-3X/ Z2FS10-2X/V Z2DB6VC2-4X/100 Z2DB10VD2-4X/315V Z1S6F05-4X/V Z1S22T1-1X/V Z1S1OP1-33/V Z1S16P1-3X/V Z1S16F1-1X/V Z1S10T2-3X/V Z1S10T1-3X/V Z1S10P1-3X/V Z1S10E2-30/V Z1S10C2-3X/V Z1S10C1-32/V WMM10D-3X/OF VT-VETSY-1-1X/1-2-1-1 UPE2-11/2.2R2.55/7ANT-BV1+01115995 SV20GA1-4X/V SV10PA1-4X SV10PA1-4X SV10GB1-4X SL52PA2-1X/V SL10PA1-4X/ SL10PA1-4X S30A1.0/ S21.0 S20A0.0 S11.0/ S10A1.X/ S10A1.0/ RVP16-10 PVV4-1X/122RA15RMC PV7-1X/63-71RE07MCO-16 PV7-17/16-20REOMCO-16 M-SR8KE05-1X/V M-SR8KE02-1X/V M-SR30KE05-1X/ M-SR30KE02-1X/V M-SR25KE05-1X M-SR20KE05-1X M-SR20KE05-1X M-SR20KE02-1X/V M-SR10KE00-1X M-SR10KD02-1X/ MR700F-P1N1N1N1N MK52F1-2X/V MK30G-1X/V MK15G1.2.
