Product performance and uses low noise vane pump: PV2R series of high pressure is the independent research and development of domestic high-performance products with state-of-the-art performance, knot absolutely reasonable, good reliability, low noise and minimal pulsation, stable quality. Seiko products manufacturing, in particular, to adapt to the requirements of high precision and low noise devices are widely used in the cutting machinery, plastics machinery, leather machinery, forging machinery, construction machinery and other fields. , Product technical parameters: 1, the nominal displacement, "4", "6", "8" pump and pressure more than 16MPa use, speed should not exceed 1450r/in 2, large displacement high speed single pump and the corresponding dual The pump should reduce the suction inlet negative pressure. 3, using synthetic hydraulic oil and aqueous hydraulic fluid, the maximum speed limit 1200r/min. For special occasions that require low noise, the proposed work speed selection 1000r/min.
