Product type-description:
VDD series vertical multistage pump is radial split, double shell centrifugal pump, with radial guide vane, guide shell type space guide vane two types of structure. The guide shell type space guide vane structure has stable hydraulic performance and small radial size. Its multi-point support sliding bearing structure is safe and reliable. The bushing can be made of high wear-resisting graphite or composite material to meet the use of low temperature and low specific gravity.
VDD Series is a pump of vertical multiple, radially split and radial diffuser.It is designed according to API610 standard,VS6 type.Rolling bearings of this pump are lubricated by thin oil,and hydraulic sliding bearing is multi-point supporting structure.At the same time,we consider and design carefully in the respects of support, cooling, installation and maintenance.A variety of auxiliary and monitoring systems make this series of pumps safe and reliable.
Parameters:
Standard:API610
Capacity:20~800 m3/h
Head:~1000m
Pressure:15.0MPa
Temperature:-80~180ºC
Application:this series of pumps is mainly used in refinery, petrochemical, coal chemical industry, power plant, cryogenic engineering, pipeline pressure regulating, condensate extraction, offshore platforms, tankers.
Cross-section Diagram:
1.The temperature measuring interface can be used to monitor bearing service condition, and ensure that the equipment runs under best condition.
2.Rolling bearing structure uses thin oil lubrication and the effect is good. The design of water cooling and air cooling structure can effectively reduce bearing chamber temperature, and is suitable for high temperature conditions.
3.Seal chamber conforms to API682 standard; all kinds of seals and auxiliary systems can be configured according to working conditions.
4.The balancing drum is used to balance axial force and the effect is good. Bearing load is small and will not be affected by bearing position.
5.Safe and reliable ways of shaft connection well ensure the accuracy of shaft, increase the insertion depth of the pump and expand application range of the pump.
6.Multi-point supporting sliding bearing structure;the bearing spacing conforms to the API610 requirements;high safety and reliability.The bushing adopts high wearable graphite or composite materials.
7.Radial diffuser structure, compact structure, relatively high single-stage impeller, suitable for high head conditions.
8.Impeller has good suction performance, with low NPSH, the pump in the same condition, effectively shortening the pump insertion depth, to ensure the pump's reliability.
