Description
Technical field
The present invention relates to a kind of pump, specially a kind of high-performance major axis centrifugal pump.
Background technology
The API610 specifications that American Petroleum Institute (API) promulgates, are the specifications that world's pump industry has significantly affecting power.In 20 generation
Record the mid-90, the problem of American Petroleum Institute (API) is in the presence of solution specification has promulgated API610 the 8th edition《Oil work
Industry, heavy chemical industry and a kind of high-performance major axis centrifugal pump of gas industrial》Specification.Stability of the specification in pump, reliability
Tightened up requirement is all proposed in terms of property, operating characteristics and service life, is mainly reflected in：Sealing, material, vibration, bearing,
All many-sides such as rotor dynamics, accessory system.The pump industry of China is centrifuged for a kind of high-performance major axis of horizontal multi-stage at present
Pump is still according to J B/T8059-96 using more《High pressure water feeding pump for boiler》Specification, API610 sixth versions, the 7th edition rule
Model manufactures and designs multistage pump.Due to the industries such as electric power, oil, chemical industry develop rapidly and environmental protection requirements at the higher level, root
According to JB/T8059-96《High pressure water feeding pump for boiler》The multistage pump that specification, API610 sixth versions, the 7th edition Specification Design are produced,
There is apparent limitation using upper, pump shaft fracture, sealing leak usually occurring, bearing life is short, pollute environment
Etc. phenomenon.
The content of the invention
