Description
Technical field
The utility model relates to a kind of large-scale pump room formula, the special-purpose pilot system of centrifugal cargo oil pump peculiar to vessel, is applicable to that particularly flow is greater than 1500 m
3/ h, pressure head are greater than a kind of large centrifugal cargo oil pump testing apparatus of 100m level pump room formula cargo oil pump.
Background technique
Cargo oil pump is the special device on the oil carrier, and its purposes is when the oil carrier landing pier, through the corresponding pipeline on the ship Cargo Oil in oil carrier cabin is transported to and carries oily equipment or oil depot on the harbour.Because the oil gas of Cargo Oil volatilization is inflammable, explosive and can produce pollution to environment, so the safety reliability of cargo oil pump is an important problems in its operation process.The safety reliability of cargo oil pump should provide corresponding assurance respectively by design, manufacturing and using process.For the danger that prevents that oil gas from causing, on oil carrier, except that adopting the separation sealing isolates pump room and cabin, simultaneously to Cargo Oil pump performance, reliability require increasingly high.Like 5.1.1b in GB3216-2005 " rotary motive power pump hydraulic performance acceptance trial ") the middle proposition: test should be carried out on the test stand of factory of manufacturing firm.Simultaneously, in GB10832-2008 " marine centrifugal pump, peripheral pump general technical specifications ", also propose in 4.1 environmental conditionss: pump should be able to be stablized under following marine condition, work reliably, has comprised temperature, humidity in the marine condition, has inclined and shake and vibrate.These requirements of NBS; To examine the environmental suitability of examining cargo oil pump through product testing exactly; Not only as the whether qualified acceptance of product or the decision-making foundation of rejection, but also can find to have the product of latent defect, thereby improve the reliability of cargo oil pump.
