IR-type single-suction single-suction horizontal hot water centrifugal pump structure

First, the product overview IR-type single-suction single-suction horizontal hot water centrifugal pump, the structure of the horizontal suspension, radial section, the rear door, the center support, suitable for conveying high temperature cleaning medium. Products meet GB5656-1994 "centrifugal pump technical conditions (II)" and GB3215 "refinery, chemical and petrochemical processes centrifugal pump general technical conditions." Mainly used in metallurgy, chemical industry, power plants, heating, textile, waste heat utilization, heat exchange devices. IR pump for the single-stage single suction Horizontal Hot Water Centrifugal Pump Structure II, the product features 1, energy-efficient: CFD CFD, analysis and calculation of the pressure distribution within the pump and the velocity distribution to optimize the pump flow channel design , To ensure that the pump has a high efficiency of the hydraulic line, improve the efficiency of the pump. 2, high temperature structure: the pump body support center to solve the pump in the delivery of high temperature medium to prevent high temperature pump thermal expansion caused by inconsistencies in the stress concentration and the coupling on the center of change. Pump support, pump cover, suspension body (bearing part) and the machine cover gland have cooling chamber, respectively, at different temperatures with cooling water cooling or air cooling. 3, bearings: bearing cylindrical roller bearings and two angular contact bearings supporting the use of thin oil lubrication, bearing capacity increased significantly. Bearing design life of 25,000 hours. 4, shaft seal: optional soft packing seal and mechanical seal. 5, Coupling: Adopt flexible pin shaft coupling, high transmission precision. 6, auxiliary pipeline: According to API 610 version 8 requirements configuration. 7, pressure: design pressure of 4.0MPa, high pressure. Third, the working conditions Flow: 3.8 ~ 660m3 / h Head H: 7 ~ 240m Temperature: ≤ 175 ℃ (HT200) 175 ℃ ~ 230 ℃ (hot water) 230 ℃ ~ 400 ℃ (heat medium)
