The Vickers PVB series includes models such as PVB5/6, PVB10/15, PVB20/29, بفب45, and PVB90.
النزوح
The geometric displacement of different models varies. على سبيل المثال, PVB5 has a displacement of 10.55 سم³/ص (0.64 في³/ص), PVB10 has 21.10 سم³/ص (1.29 في³/ص), PVB20 has 42.80 سم³/ص (2.61 في³/ص), PVB29 has 61.60 سم³/ص (3.76 في³/ص), PVB45 has 94.50 سم³/ص (5.76 في³/ص), and PVB90 has 197.50 سم³/ص (12.0 في³/ص).
Maximum Shaft Speed
The maximum shaft speed for most models in this series is 1800 دورة في الدقيقة.
تقييمات الضغط
When using anti-wear hydraulic oil, the maximum outlet pressure of PVB5 and PVB6 is 140 حاجِز (2000 PSI), while for PVB10, بفب20, and PVB45, يمكن أن تصل 210 حاجِز (3000 PSI). When using water glycol or water-in-oil emulsion, the maximum pressure values are relatively lower. على سبيل المثال, for PVB10, إنها 140 حاجِز (2000 PSI) with water glycol and 100 حاجِز (1500 PSI) with water-in-oil emulsion.
خيارات التحكم
The variable displacement models offer several control options, مشتمل:
Pressure compensator with or without a remote control facility.
Pressure compensator with adjustable displacement control.
Load sensing compensator.
Mechanical (رافعة) يتحكم.
Handwheel control.
وزن
The weight of different models also differs. على سبيل المثال, PVB5 weighs approximately 8 كجم, PVB10 and PVB15 weigh about 15 kg each, and PVB20 and PVB29 weigh around 26 كجم.
