AY centrifugal pump structure

First, the product overview AY centrifugal pump is based on the AY centrifugal pump according to the American Petroleum Institute standard API610 eighth edition of the transformation and design made, the product type, installation dimensions and performance parameters remain the same with the AY centrifugal pump, there Conducive to the upgrading of the device. In order to be suitable for different operating conditions, the type of pump body are supported by the central support; bearing body optional natural cooling, air-cooled and water-cooled three; the flow of parts made of cast iron (I), steel (II) Type stainless steel (III) three; pump single-stage suction, two single-suction, single-stage double suction, multi-stage and other forms. Product implementation GB3215-82 "KGT chemical and petrochemical process centrifugal pump general technical conditions" can be used to transport medium temperature not more than 450 ℃ without solid particles of petroleum, chemical products have a certain viscosity of the media. AY centrifugal pump Second, the product features 1, the standard requirements of high: AY pump in strict accordance with the American Petroleum Institute API610 the latest version of the eighth edition of the modified design requirements, higher than the original API 610 version 6 standards. 2, high temperature structure: the pump body using the central support structure to prevent the material under high temperature creep caused by stress concentration and deformation of the pump body. Support frame, pump cover, suspension, bearing parts are equipped with cooling chamber. 3, diaphragm coupling: small size, light weight, large carrying capacity, high transmission efficiency, high transmission accuracy, suitable for high and low temperature oil and water occasions. Extended structure to ensure that maintenance can not move the motor and the removal of pipelines. 4, mechanical seal: According to different conditions choose single-end machine seal, double-end machine seal, metal bellows machine seal, sealed and reliable. 5, bearings: bearing a single row of radial bearings and two rows of thrust bearings, bearing capacity. Long design life (> 25000 hours), lubrication for thin oil lubrication. 6, all sealed shaft: shaft seal and "O" ring seal to ensure that the shaft does not touch the media to improve the life of the shaft. 7, high balance accuracy: rotor balancing accuracy of G1.0 level. Third, the working conditions Flow: 9m3 / h ~ 500 m3 / h (water state) Head: 38m ~ 650m (water state) Medium temperature: -45 ℃ ~ +450 ℃ Ambient temperature: ≤ +40 ℃
