-柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油。 柱塞在缸体中要往复运动，因此，它的运动量很大，在工作过程中需要承受巨大的摩擦力，因此，柱塞要求高的硬度、耐磨性和使用寿命以及高的精度等。通过研究，采用淬火热处理可以满足柱塞的技术要求。 淬火是将钢加热到临界温度Ac3（亚共析钢）或Ac1（过共析钢）以上温度，保温一段时间，使之全部或部分奥氏体化，然后以大于临界冷却速度的冷速快冷到Ms以下（或Ms附近等温）进行马氏体（或贝氏体）转变的热处理工艺。淬火工艺在现代机械制造工业得到广泛的应用。机械中重要零件，尤其在汽车、飞机、火箭中应用的钢件几乎都经过淬火处理 PV016R1K1JHNMMC PV020R1K1A1NMMC PV020R1K1T1NUPR PV020R1L1T1NMFC PV023L1K1T1NMMC PV023R1K1A1NMMC PV016L1K1T1NMMC PV016R1K1AYNMRC PV016R1K1A1NMRC PV016R1K1T1NEL1 PV016R1K1T1NMF1 PV016R1K1T1VMMC PV016R1L1T1NMRC PV028R1K1A1NMMC PV028R1L1T1NMMC PV046R1K1AYNHLZ PV046R1K1AYNHL1 PV046R1K1T1NHL1 PV032R1L1T1NMFC PV046L1K1T1NMFC PV046R1K1KJNMFC PV046R1L1T1NMFC PV046R1L1T1NMR1 PV046R1K1T1NGC1 TF0195HW080AAFX PVAC1PMMNS35 PVAC1PMMNS3520 PV016R1K1JHNMMW PV023R1K1AYNMR1 PV016R1K1T1NMRC PV020R1K1T1NMFC PV028R1K1T1NMFC PV046R1K1AYNGL1 PGP640B0800CE4A4MT6T4S-620A019 TE0100LW260BBCN TE0165LW260BBCN PGP620A0500CD1H3NT5T3B1B1 PV032R1K1T1NMT1 PV032R1K1T1NMT14645 PGP640B0600CE4K3NT5T3S-620A041 PV016R1K1JHNMFC+PV016R1L1T1NMF PVCMPCNS PVCMPCNS45 PVACMS PVACMS45 PV032R1K1T1WMMC PV046R1K1T1WHLC SK-PVBG2N145 SK-PVBG2V145 SK-PVBG2W145 PV040R1K1AYNMFC PVCMAPVN1 PV028R1K1T1NMR1 PVCMAL1N1 PV040L1K1T1NMMC P2105C000023 PV040R1K1T1NMMW PV040R1K1T1NGL1 PV046R1K1AYNMMW PV046R1K1AYNMMW+PGP511A0190CA1 PV023R1K1AYNMMW+PGP511A0190CA1 PV023R1K1T1NMMW PV046R1K1T1NMMW TF0195MW470BBBJ PV023R1K1AYNMMW PV016R1K1T1NMMW PGP620B0500CD1H3NE8E6C-620A016 PGP640A0800CD1H3VT6T5B1B1 P2105C000024 PV040R1K1T1NEL1 PV046R1K1JHNUPR SK-PVBG1N145 SK-PVBG1W145 PV016R1K1T1NMMZ TF0080EW260BBBF PV046R1K1T1WMMC PV016R1K1T1NMRW TE0330MN260AAAB PGP640B0400AD1H3MT5T3S-620A041 PV046R1K1JHNMM1 TE0100CW261AABK PV046R1K1T1NGLZ+PVAC1ECMNSJW35 PV046R1K1T1NMM1 PV020R1K1AYNMMC+PGP511A0140CA1 PV032R1K1AYNDCC+PGP505A0040CA1 PGP640A0650CD1H3NT6T4B1B1 PV046R1K1BBNMRC PV046R1K1BBNMRC4645 PV016R1K1T1NMRZ+PVAC1PCMNL35 PV023R1K1T1VMFW PV023R1K1T1VMFW4545 PV023R1K1AYNMF1+PGP505A0060CA1 PGP620A0290CD1H2NE6E5B1B1 SK-PVS008012 SK-PVS008-012 PVACPC35NL DRUCKPILOTCARTRIDGE PV040R1K1T1NKL1 PV040R1K1T1NKL14645 PV028R1K1T1NCCC PV028R1K1T1NCCC4545 PV270R1K1T1N2CC PV270R1K1T1N2CC4645 PV032R1K1T1NDLZ+RE06M35T2N1F02 PGP620A0440AD1H3NE8E6B1B1 PV028R1K1T1NELCX5926 PV028R1K1T1NELC4545X5926 PV032R1K1AYNMMW PV032R1K1AYNMMW4645 PV046L1E1BCN001 PV046L1E1BCN00146 PV032R1K1AYNMMW+PGP511A0190CA1 PVCMAU2N1 PVCMAU2N145 PV023L1E1AYN001 PV023L1E1AYN00145 PV046R1K1A1WMMZ PV046R1K1A1WMMZ4645 SEAL KIT PGP640(2GR-LIP-S.M) PV046R1D3CDNMMZ+PV046R1E3BCNMM PVAC2MCMNLJW35 PVAC2MCMNLJW3520 PV032R1L1BBNMMZ PV032R1L1BBNMMZ4645 PV046R1D1B1NMCC PV046R1D1B1NMCC4645 PV046R1K1KJNMM1 PV046R1K1KJNMM14645 PGP517B0260CD1H3MJ9N2C-517B026 PV016R1K1JHNMMC+PV016R1L1T1NMM PV032R1K1T1NMRZ+PVAC2MCMNLJW35 PV016R1K1T1NCL1 PV016R1K1T1NCL14545 RK-PVS08AZC2 RK-PVS16AZC2 RK-PVS25EHC2 RK-PVS32EHC2 PGP511T0110CA1H2MJ7J5C-511S008 PGP620A0260AD1H3NT4T2B1B1 PV SHAFT SEAL CARRIER SINGLE VIT PV020R1K1T1NMMW RK-PVS40AZC2 RK-PVS40EHC2 RK-PVS50AZC2 RK-PVS50EHC2 PV020R1K1T1NMM1 SEAL KIT PGM511 (LIP-S.H-BIG) PV023R1K1T1NHLC
