      High-pressure decaling system with model SD pump or model ZD pump as main machine, integrating pump, valve, compressor, decaling box, pipeline and high/low voltage electrical equipment by which all equipment and devices in the pump station can be centrally controlled and interlocked. Use of advanced technologies, including hydraulic speed regulation, variable frequency speed regulation, remote monitoring of operation status, and failure diagnosis, obtains a systemic integrity of mechanical, electron and instrument, machine, and realizes the supply of system in full sets. CPIC possesses the advanced technology and ripe experience in undertaking the turnkey contract of complex installation including design, fabrication, installation, commissioning of system and technical training. These decaling systems can be found in more than 90% iron & steel enterprises, become the preferred products for steel industry.   1.General descriptionModel SD pump,a high-pressure double casing multistage centrfugal pump,features unique design,high reliability and applicability,offers many advantages over other type of centrifugal pumps in the field of being especially suitable for special duty which changes frequently,was designed specially for high-pressure descaling in steelworks,high pressure water injection for oilfeld and oil transferring,and boiler water feeding,etc.   Model SDS high-pressure descaling pump transfers soild-liquid state medium in which soild content is up to 8%.   Model SDZ high-pressure water injecting pump handles returned unclean injection water or corrosive liquid.   Model SDY crude oil transfer pump delivers crude oil containing water and sand.   Model SDG high-pressure boiler feed pump tranfers liquid with temperature up to 120℃.   SD pump went through long time operation in large-scale steelworks and offshore oil platform in our country as Anshan,Wuhan,Baoshan and Panzhihua steelworks,and China Offshore Oil Platfom.Mean failure free operation period has been up to 30000 hrs,having high reputation.   The rotating direction of pump is clockwise when viewed from the prime motor. 2.Structure Features   With symmetrical design of impeller parts,axial force of each stage of impeller is canceled each other.Tremendous thrust in pumping chamber can be self-balanced without balance plate or drum device.This makes a breakthrough at the stucture design bottleneck of conventional centrifugal pump for which the operation duty range is narrow and shaft breaking is difficult to avoid under large fluctuant duty.   The inner casing emerges a 180°symmetric double volute passage.If the duty point deviates from the design point,the radial forces produced in pumping chamber are canceled and self –balanced via the double volute passage,achieving smooth operation and extremely low vibration quailty .the design is suitable for the weak foundation and poor rigidity site,especially offshore oil platform.   The pump was designed with thrust bearing at the end, which can,when sudden change of system duty takes place,bear unexpected huge axial force to protect the pump from being damaged,showing mulitple reliability design concept.   The pump is firm and durable,and runs smoothly with low noise.  

  Hi-pressure self-balance multistage centrifugal pump series have four kinds of casing structure:the sectional,the volute type double casing,the double casing type with drawout inner casing and rotor,and the horizontal split single casing,which take the lead in domestic self-balance multistage centrifugal pumps area,widely used to transfer corrosive solutions in oilfield water injection,steelwork descaling,oil transfer,hi-pressure boiler feed,petrochemical product,and nuclear power plant.CQPI possesses a good reputation with the long-term operation of offered pumps in many steel corporations,ocean oil platform and petroleum chemical devices like Anshan Steel Corp.,Wuhan Steel Corp.,CNOOC,SINOPEC,etc. Opposed arrangement of impellers can realize the self-balance of axial force and radial force,and non-contract spiral seal almost eliminates wear-and-tear parts.Those pumps have unique structure,high reliability and adaptability,in particular suitable for operating conditions which change frequently.Capacity:120-600m3/h,pressure up to:30 MPa. ZDS Descaling pump capacity ranges from 60m3/h. head from 800 m to 2700m, suitable for descaling of rolled steel.oilfield water injection ,boiler feed etc.   

  SD Double Casing PumpCapacity ranges from 200m3/h to 500m3/h, head from 1000m to 2700m,suitable for descaling of rolled steel, boiler feed,and hydrocarbon transfer at normal atmospheric temperature.
