力士樂(lè)rexroth伺服閥專賣 力士樂(lè)伺服閥由永磁力矩馬達(dá)、噴嘴、檔板、閥芯、閥套和控制腔組成(見圖)。當(dāng)輸入線圈通入電流 伺服閥時(shí),檔板向右移動(dòng),使右邊噴嘴的節(jié)流作用加強(qiáng),流量減少,右側(cè)背壓上升;同時(shí)使左邊噴嘴節(jié)流作用減小,流量增加,左側(cè)背壓下降。閥芯兩端的作用力失去平衡, 閥芯遂向左移動(dòng)。高壓油從S流向C2,送到負(fù)載。負(fù)載回油通過(guò) C1流過(guò)回油口,進(jìn)入油箱。閥芯的位移量與力矩馬達(dá)的輸入電流成正比,作用在閥芯上的液壓力與彈簧力相平衡,因此在平衡狀態(tài)下力矩馬達(dá)的差動(dòng)電流與閥芯的位移成正比。如果輸入的電流反向,則流量也反向。表中是伺服閥的分類。 伺服閥主要用在電氣液壓伺服系統(tǒng)中作為執(zhí)行元件(見液壓伺服系統(tǒng))。在伺服系統(tǒng)中,液壓執(zhí)行機(jī)構(gòu)同電氣及氣動(dòng)執(zhí)行機(jī)構(gòu)相比,具有快速性好、單位重量輸出功率大、傳動(dòng)平穩(wěn)、抗干擾能力強(qiáng)等特點(diǎn)。另一方面,在伺服系統(tǒng)中傳遞信號(hào)和校正特性時(shí)多用電氣元件。因此,現(xiàn)代高性能的伺服系統(tǒng)也都采用電液方式,伺服閥就是這種系統(tǒng)的必需元件。 伺服閥結(jié)構(gòu)比較復(fù)雜,造價(jià)高,對(duì)油的質(zhì)量和清潔度要求高。新型的伺服閥正試圖克服這些缺點(diǎn),例如利用電致伸縮元件的伺服閥,使結(jié)構(gòu)大為簡(jiǎn)化。另一個(gè)方向是研制特殊的工作油(如電氣粘性油)。這種工作油能在電磁的作用下改變粘性系數(shù)。利用這一性質(zhì)就可通過(guò)電信號(hào)直接控制油流。 :李兵 : : 公司地址:上海市黃浦區(qū)北京東路668號(hào)上??萍季┏菛|樓20樓C2 力士樂(lè)rexroth伺服閥專賣 力士樂(lè)型號(hào)如下: HED10A4X/350L24 DBW20A2-5X/315-6EG24N9K4 HM100-250-B-M20*15-FF DB30-2-5X/315 S15A10 LFA40RF-7X ZDC25P-2X/XM 4WRZE25W8-325-7X/6EG24N9EK31/F1D3M SL30PA1-4X DBD20K-1X/315 M-SR20KE02-1X 4WE10C3X/CG24N9K4 LC40DR40E-7X LFA40DB2-7X/210 4WRZE32W8-520-7X/6EG24N9EK31/F1D3M LC40A05E-7X FD32PA2X/B06V 4WEH16J7X/6EG24N9ETK4 Z2S16-2-5X Z2FS16-3X/S2 4WEH25J7X/6EG24N9ETK4 Z2S22-2-5X Z2FS22-3X/S2 D2773A3025 D2153B6012 RZGD-A-033/21031 A2FE90/61W-VAL100 OMM32151G0033 HED80A12/200K14 HED80A12/350K14 TYP:FMA-2N-MB/206 PD20/MATRL/120kg/cmbG1R11450 DZ20-2-5X/100 A2FE90/61W-VAL10 4WRZE16E150-70/6EG24N9ETK31/A1D3M A10VS071DFR/31R-PPA12N00 H06SDV2PTB125barA500bar CMZ-050TB EDS344-2-016-000 TVPE:ARV-VUU GE36-4-A44324VDC26W KDG4V-5-2C50-N-E-MV-H7-30 1E15P6-50S 2FRE164X/160LB A2FO-250/60RPB05 QAE-E6/10D-BU Z2S22-40 ETS1701-100-000 2103-018,00HDG1/4 S100-AC-AC-0100(Ф2mm,1m) 4WRZ-25E3-325-50/6A24NETZ4/D3M(含放大板) DRV-1-01500PSI A10VS028DR30R-PPA12DV00/ CV-06G-05/20 WD-G02-B2-D2-N VT-VSPA2-50-10/T5 FD16FA21/B03V DB1010-5X/200 NHT301-3C-1CS4Y2 RFB-400X20-Y LXZ-250X80-YY GE2G3/4'' Z2S10-3-34 Z2FS10-7-33/V ZDB10VP-2-4X/200 Z1S10P-1; HE4524S16RPSBLS HH6220C16RTSBR220VAC QUQ2-20X10 CYL1MP5/400/160 CYLMP5/250/140 CY81MP5/50/28 CYA1MP5/5028 R900561278北京現(xiàn)貨 R900561290 R900052392 D663-4007/L03HABD6VSX2-A D663-4307/P02JONF6VSX2-A D661-4033P80HAAF6VSX2-A D661-4651/G35JOAA6VSX2HA D661-4636/G60KOAA5VSX2HA "S/N96762181036798597 PATNO0513870220 CODE0513R18C3VPV164SM21H2B01" J761-003,TYPE:S63JOGA4VPL D3DW20BVZP40XB510 XA,02-365591,220VDC,30W 072-559ATYPE:S15POFA4VBL 4WE6D62/EG220N9K4/V SV4-20(15)57-80/40-10-S451ASSYNO3025217壓力210Bar 4WE10D33/OFCG220N9K4/V220VDC35WNXR:R901025073 3WE10A33/CG220N9K4/V220VDC35WNXR:R901083655 4WE6D60/BG24NXDZ2/VGH45-2MN M-3SE6U66/420LG24NXDZ2/VGH45W-2M DHA-0631/2/A/PA-M24DC DPHA2631/2/D/PA-M24DCQA-24DC DPHA2713/D/PA-M24DCQA-24DC DPHA1631/2/D/PA-M24DCQA-24DC A10VSO140DR/31RPPB12N00 4WE10E33/CG24N9K4 PVR24F/11-RE95022/0502 LT05MKA-3X/100/02M LT06-A06-30/200B80/02M 4WE6D6X/EG24N9K4 4WE6D6X/OFEG24N9K4 4WE10D3X/CG24N9K4 DBET-5X/315G24K4V-21 M-3SED10UK1X/350CG24N9K4 M-3SED6UK1X/350CG24N9K4 4WE10U12-3X/CG24N9K4 4WE10C3X/CG24N9K4 3WE10A73-3X/CG24N9K4/A12 4WE10D73-3X/CG24N9K4/A12 4WE6Y6X/EG24N9K4 4WE6E6X/EG24N9K4 4WE6H6X/EG24N9K4 HBD8OA-2X/350K145 DR10DP2-4X/75YM 3WE6A6X/EG24N9K4 4WE6C6X/EG24N9K4 4WE6U12-6X/EG24N9K4 3WE6A73-6X/EG24N9K4/A12 M-3SED6CK1X/350CG24N9K4 HBD8OA-1X/100Z15L24KS VT-2000-5X VT-3002-2X/32D HM12-1X/315(4-20MA) 4WE6J6X/EG24N9K4 A10VS028DRF1/31R-PPA12N00; A10VS028DRF1/31R-PPA12N00 M-3SED6CK13/35OCG24N9K4/V M-SR8KE05-1X M-SR10KE05-1X M-SR20KE05-1X DB10-2-5X/315X ZDR6DP2-4X/150YM Z2FS6-2-4X/2Q LFA16E-7X/CA10DQMG24F LFA25E-7X/CA10DQMG24F 4WE6D6X/0FEG24N9K4 MCR10D940L60Z-32/B7M DBET-52/50G24K4M M-3SED6CK13/35OCG24N9K4 4WE6D6X/EG110N9K4/V+Z5L 4WE6D6X/EG110N9K4/V+Z4 HA4VSO250HD1G+HA4VSO250LR3G HA4VSO250HD3G+HA4VSO250LR3G DB10-3-5X/315 DBDS20K1X/315 DR10-4-5X/200YM DR15G-4-5X/200YM ZDR10DP-2-5X/150YM Z2FS10-5-3X/V 4WE6D6X/EG24N9K4 M-3SEW10U1X/420MG24N9K4 4WRAE10W1-60-2X/G24K31/F1V; 4WMM10E3X/F
