Venda quente Bomba de pistão hidráulica V38D12RAX-95 Controle de pressão duplo China Fabricante Bomba de pistão de óleo hidráulico V38D

V38D12RAX-95 Hydraulic Oil Piston Pump

Theoretical Displacement	~38 cm³/rev	Determines maximum flow output (flow = displacement × speed × volumetric efficiency).
Maximum Continuous Pressure	28 MPA (4060 psi)	Safe long-term operating pressure; exceeding this causes premature wear of pistons, valve plates, or seals.
Pressão de Pico	35 MPA (5075 psi)	Short-duration pressure (≤5 segundos) for emergency heavy loads (por exemplo, sudden machine jolts); avoid prolonged use.
Rated Speed	1000 – 2500 RPM	Optimal speed range for high volumetric efficiency (≥91%) and low noise (≤76 dB(A) at 1m distance).
Minimum Speed	≥600 rpm	Prevents cavitation (air bubble formation in oil); running below 600 rpm reduces suction efficiency and causes flow instability.
Hydraulic Fluid Compatibility	ISOS VG 32/46/68 mineral-based hydraulic oil	Must meet cleanliness standard NAS 8 or higher (use 10 μm filtration to avoid contamination of precision internal components).
Operating Temperature Range	-15° C a +80 ° C. (5°F a +176°F)	Extreme temperatures (below -15°C or above 80°C) thicken/thin oil, reducing pump efficiency and damaging seals.
