叶片泵的流量与转速成线性关系,相对于低转速的螺杆泵,高转速的螺杆泵虽能增加了流量和扬程,但功率明显增大,高转速加速了转子与定子间的磨耗,必定使螺杆泵过早失效,而且高转速螺杆泵的定转子长度很短,较易磨损,因而缩短了螺杆泵的使用寿命。 通过减速机构或无级调速机构来降低转速,使其转速保持在每分三百转以下较为合理的范围内,与高速运转的螺杆泵相比,使用寿命能延长几倍。 R901085379 PVV21-1X/055-027RB15DDMB R901084887 PVV52-1X/193-045RA15DDMC R901083429 PVV54-1X/139-113LB15DDMC R901081361 PVV21-1X/055-018RA15DDMB R901080702 PVV5-1X/193RA15DVC R901080473 PVV52-1X/193-068LA15UUMC R901079432 PVV1-1X/027RA15RMB R901078751 PVV51-1X/139-018RJ15DLMC R901077322 PVV51-1X/193-027RB15UUMC R901076988 PVV5-1X/162LA15DMC R901075202 PVV42-1X/113-055RA15UUMC R901075200 PVV41-1X/122-046RA15UUMC R901074802 PVV21-1X/060-018RB15DDMB R901069521 PVV51-1X/139-027RB15LLMC R901066306 PVV21-1X/040-018RA15RRMB R901063719 PVV42-1X/098-068RB15UUMC R901063622 PVV2-1X/055RA15LMB R901059672 PVV54-1X/162-122RA15DDMC R901061186 PVV51-1X/193-018RA15LDMC R901057121 PVV51-1X/193-046RA15DDMC R901055602 PVV4-1X/113LA15UMC R901053049 PVV51-1X/193-046RA15DLMC R901053014 PVV51-1X/193-046LA15DLMC R901050795 PVV54-1X/183-069RA15UUMC R901045673 PVV4-1X/098RA15LMC R901044270 PVV2-1X/040RA15UVB R901042655 PVV54-1X/154-082RA15UUMC R901042651 PVV41-1X/082-040RA15UUMC R901042169 PVV21-1X/045-040LA15UUMB R901040968 PVV1-1X/040RA15UVB R901040503 PVV1-1X/036RJ15DVB R901037970 PVV1-1X/018RA15RMB R901036232 PVV51-1X/193-027RA15UUMC R901034701 PVV54-1X/193-122RJ15DDMC R901031937 PVV2-1X/055RA15DVB R901031658 PVV21-1X/068-046RA15UUMB R901028783 PVV2-1X/045LA15UMB R901026966 PVV54-1X/154-122RB15UUMC R901024714 PVV51-1X/162-046RA15DDMC R901024704 PVV4-1X/082RJ15UMC R901023158 PVV21-1X/045-040RA15UUMB R901020330 PVV41-1X/122-027RA15DDMC R901020329 PVV52-1X/193-045RB15LLMC R901018208 PVV54-1X/139-122RJ15UUMC R901014437 PVV4-1X/082LA15UMC R901012238 PVV4-1X/122RA15DVC R901012150 PVV41-1X/082-018RB15UUMC R901009013 PVV21-1X/040-027RA15UUMB R901004734 PVV21-1X/055-036RA15UUMB R901002834 PVV41-1X/069-018RJ15UUMC R901002823 PVV52-1X/162-068RA15UUMC R900978703 PVV4-1X/082RA15DVC R900977523 ABAPG-PVV /017D493A R900977417 PVV5-1X/162RA15RMC R900976172 PVV41-1X/098-018RA15UUMC R900976001 PVV54-1X/162-082RA15DDMC R900973408 PVV1-1X/027RA15UVB R900972481 PVV42-1X/122-055RA15UUMC R900970917 PVV5-1X/162RB15DVC R900970135 PVV1-1X/036LA15UMB R900969172 PVV21-1X/045-018RB15URMB R900969090 PVV21-1X/040-018LA15URVB R900968783 PVV21-1X/045-027RA15UUMB R900968642 PVV2-1X/055RA15UVB R900968079 PVV21-1X/045-040RA15UDMB R900968078 PVV1-1X/040LA15UMB R900968076 PVV2-1X/060LA15UMB R900966979 PVV41-1X/069-018RA15DDMC R900965263 PVV42-1X/122-040RA15UUMC R900962361 PVV54-1X/193-122RA15UUMC R900961088 PVV54-1X/193-122RB15DDMC R900957021 PVV21-1X/055-046RA15UUMB R900954326 PVV5-1X/139RA15UMC R900952889 PVV21-1X/055-027RA15UUMB R900950523 PVV21-1X/060-036RA15DDMB R900949682 PVV5-1X/183LA15DMC R900949681 PVV5-1X/193LA15DMC R900949676 PVV51-1X/183-046RA15DDMC R900949510 PVV54-1X/139-082RB15DDMC R900949069 PVV2-1X/060RA15RMB R900948951 PVV21-1X/068-040RA15DDMB R900948873 PVV51-1X/139-046LB15UUMC R900948168 PVV21-1X/045-027RA15DDMB R900947492 PVV2-1X/045RA15UVB R900947385 PVV5-1X/139RA15RVC R900946959 PVV2-1X/040RJ15UMB R900946296 PVV5-1X/139RA15DVC R900945850 PVV4-1X/082RJ15DMC R900945761 PVV4-1X/122RA15LMC R900945544 PVV5-1X/193LB15DMC R900945381 PVV21-1X/040-036RB15DUMB R900945229 PVV54-1X/193-098RB15DDMC R900945128 PVV1-1X/018RJ15UMB R900945121 PVV54-1X/183-098RB15DUMC R900944546 PVV5-1X/193LA15UMC R900944135 PVV41-1X/122-018RA15DDMC R900943716 PVV5-1X/154RA15UMC R900943199 PVV2-1X/055RB15DMB R900943054 PVV4-1X/113RA15UVC R900942737 PVV4-1X/082LA15DMC R900942489 PVV5-1X/193RB15UMC R900942298 PVV2-1X/045RJ15UMB R900942277 PVV52-1X/193-060RA15UUMC R900942115 PVV2-1X/040RA15DMB R900942114 PVV1-1X/018RA15DMB R900942110 PVV5-1X/183RA15UMC R900942109 PVV52-1X/139-068RA15UUMC R900942108 PVV4-1X/098RJ15UMC R900941961 PVV54-1X/139-082RA15UUMC R900941702 PVV1-1X/046RJ15UMB R900941701 PVV51-1X/183-040RA15UUMC R900941700 PVV51-1X/193-046RA15UUMC R900941699 PVV4-1X/098RA15RMC R900941698 PVV2-1X/055RA15RMB R900941697 PVV42-1X/113-068RB15URMC R900941692 PVV4-1X/122RJ15DMC R900941691 PVV2-1X/068RJ15DMB R900941684 PVV1-1X/040RJ15DMB R900941572 PVV2-1X/060RA15UMB R900940633 PVV1-1X/018RA15UMB R900940588 PVV21-1X/040-027RA15DDMB R900940587 PVV21-1X/040-018RA15DDMB R900940446 PVV2-1X/055RJ15UMB R900940260 PVV1-1X/027RJ15UMB R900940215 PVV2-1X/060RB15DMB R900939702 PVV52-1X/193-055RA15UUMC R900939526 PVV1-1X/036RJ15UMB R900939497 PVV54-1X/139-098RB15UUMC R900939347 PVV2-1X/055LA15DMB R900939078 PVV5-1X/193RJ15DMC R900939075 PVV1-1X/027RJ15DMB R900939042 PVV5-1X/193RA15RMC R900939041 PVV5-1X/183RA15RMC R900939040 PVV2-1X/068RA15RMB R900938819 PVV4-1X/113RA15UMC R900937555 PVV41-1X/082-040RA15DDMC R900937335 PVV52-1X/193-068RA15UUMC R900937333 PVV42-1X/082-045RA15UUMC R900937332 PVV21-1X/040-018RA15UUMB
