R88M-G2K030H-OS2-Z机床润滑系统的设计、调试和维修***，对于提高机床加工精度、延长机床使用寿命等都有着十分重要的作用。但是在润滑系统的电气控制方面，仍存在以下问题：一是润滑系统工作状态的监控。数控机床控制系统中一般仅设油箱油面监控，以防供油不足，而对润滑系统易出现的漏油、油路堵塞等现象，不能及时做出反应。二是设置的润滑循环和给油时间单一，容易造成浪费。数控机床在不同的工作状态下，需要的润滑剂量是不一样的，如在机床暂停阶段就比加工阶段所需要的润滑油量要少。针对上述情况，在数控机床电气控制系统中，对润滑控制部分进行了改进设计，时刻监控润滑系统的工作状况，以保证机床机械部件得到良好润滑，并且还可以根据机床的工作状态，自动调整供油、循环时间，以节约润滑油。1润滑系统工作状态的监控润滑系统中除了因油料消耗，油箱油过少而使润滑系统供油不足外，常见的故障还有油泵失效、供油管路堵塞、分流器工作不正常、漏油严重等。因此，在润滑系统中设置了下述检测装置，用于对润滑泵的工作状态实施监控，避免机床在缺油状态下工作，影响机床性能和使用寿命。过载检测在润滑泵的供电回路中使用过载保护元件，并将其热过载触点作为PMC系统的输入信号，一旦润滑泵出现过载，PMC系统即可检测到并加以处理，使机床立即停止运行。油面检测润滑油为消耗品，因此机床工作一段时间后，润滑泵油箱内润滑油会逐渐减少。如果操作人员没有及时添加，当油箱内润滑油到达***低油位，油面检测开关随即动作，并将此信号传送给PMC系统进行处理。压力检测机床采用递进式集中润滑系统，只要系统工作正常，每个润滑点都能保证得到预定的润滑剂。一旦润滑泵本身工作不正常、失效，或者是供油回路中有一处出现供油管路堵塞、漏油等情况，系统中的压力就会显现异常。根据这个特点，设计时在润滑泵出口处安装压力检测开关，并将此开关信号输入PMC系统，在每次润滑泵工作后，检查系统内的压力，一旦发现异常则立即停止机床工作，并产生报警信号。SquareDQOB140Bolt-OnSingle(1)Pole40AQOCircuitBreakerBrandInBoxSQUAREDQOB135CIRCUITBREAKER35AMP1POLESQUAREDQOB1351POLE35AMP120VOLTBOLT-ONCIRCUITBREAKER**SquareDQOB120VHcircuitbreaker1p20a22ktypeQOBSQUAREDQOB120GFI20A1POLEGFIPROTECTIONBOLTONBREAKERSquareDQOB120GFI1Pole20ampBoltOnGroundFaultCircuitBreakerSQUAREDQOB120CAFI20AMPCOMBINATIONARCFAULTBREAKERSQUAREDQOB120AFIQOB1POLE20AMPCIRCUITBREAKERQOBAFIBOLTONSQUAREDQOB120LOTOF1020A120VSINGLEP***EBOLTINSquareDQOB120CircuitBreaker20Amp1Pole-SquareDQOB1201Pole20Amp120/240VacCircuitBreakerQOB120-Lotof10SquareDQOB1201Pole20Amp120/240Vac(Style)CircuitBreaker-Lotof10SQUAREDQOB1201P20ASQ-DBOLTONBREAKERSQUAREDQOB1201POLE20AMP120/240VLOTOF10TAKEOUTSCIRCUITBREAKERS..SquareDQOB,20Amp,1PoleUnitCircuitBreakerSQUAREDQOBQOB36060AMP3POLE240VSQUAREDQOBQOB3603POLE60AMPBREAKERBOLTON240VWILLFITNQSquareDQOBQOB35050-Amp50A3-Pole3PBolt-onCircuitBreaker-SEEPICSSQUAREDQOBQOB270VHPOLE70AMPCIRCUITBREAKERYELLOWBoltInSAMEDAYSHIPSQUAREDQOBQOB270POLE70AMPCIRCUITBREAKERYELLOWBoltInSAMEDAYSHIPSquareDQOBQOB2702pole70ampCircuitBreakerYellowBOLTONSquareDQOBQOB2702pole70ampCircuitBreakerBlackBOLTONSquareDQOBQOB2502Pole50ampCircuitBreakerBOLTONyellowSQUAREDQOBQOB2502POLE50AMPCIRCUITBREAKERBLACKBOLTONSquareDQOBQOB240VH2pole40ampCircuitBreaker22kaBOLTONSQUAREDQOBQOB240HPOLE40AMPCIRCUITBREAKERYELLOWBoltInSAMEDAYSHIPSquareDQOBQOB1151Pole65ka15ampCircuitBreakerYellowBOLTONSquareDQOBGFCICircuitBreaker20A120VGroundFault1poleSQUAREDQOBCIRCUITBREAKERQOB32525AMP240VOLT3POLE10kASQUAREDQOBCIRCUITBREAKERQOB32020AMP240VOLT3POLE10kAOLDSTYLESQUAREDQOBCIRCUITBREAKERQOB270VH70AMP240VOLT2POLE22kASQUAREDQOBCIRCUITBREAKERQOB2100100AMP240VOLT2POLEOLDSquareDQOBCircuitBreakerQOB120AFI2OA120VSquareDQOBCircuitBreaker30A3pole240VacLL-6696SquareDQOBCircuitBreaker30A2pole240VacMG-8930SQUAREDQOBCIRCUITBREAKER30AMP3POLE240VOLTQOB330SquareDQOBCircuitBreaker20A240VacLL-2814SQUAREDQOBCIRCUITBREAKER20AMP120GFISquareDQOB40A120/240V10KAbreaker2poleHACRSquareDQob350-VhSquareDQob335SquareDQOB2-Pole60AmpTypeHACRBolt-OnCircuitBreakerSQUAREDQOB2pole80amp120/240vQOB280CircuitBreakerYellowBoltOnFlawedSquareDQOB2pole20amp120/240vQOB220VHCircuitBreakerQOB220VHSquareDQOB130QOB130CircuitBreaker30A1Pole-SquareDQOB120OneYearWarranty!SquareDQOB1pole30ampQOB130GFIBreakerGFGFIGFCIOLDSTYLEBrokenClipSquareDQOB1pole20ampQOB120GFICircuitBreakerGFIoldstyleSquareDQOB1pole15amp120vQOB115GFIBreakerGFIGFCIYellowMissingClipSquareDQO820AmpCircuitBreaker240VAC2PoleSQUAREDQO360VHQO360VHSquareDQO360CircuitBreakerSquareDQO320,3POLE20AMP240VOLTPLUGINCircuitBreaker-WARRANTY)
