ISG series single-stage single-suction vertical pipeline centrifugal pump structure
ISG series single-stage single-suction vertical pipeline centrifugal pump is a direct-connected pipeline pump structure. The impeller is installed on the motor extended shaft. The utility model has the advantages of stable operation, simple structure, convenient maintenance and repair, convenient installation and area saving Than the area of ​​more than 30% savings) and other characteristics; products meet the GB / T5657-1994 "Centrifugal Pump Technical Specifications (III)" standard; can transport medium temperature does not exceed 105 ℃ water or other physical and chemical properties similar to water liquid. Single-stage single-suction vertical pipeline centrifugal pump structure II, the product features 1, energy-efficient: CFD CFD, analyze and calculate the pump pressure distribution and velocity distribution, optimize the pump flow channel design to ensure that the pump is highly efficient The hydraulic shape of the line, improve the efficiency of the pump. 2, easy installation and maintenance: vertical pipe structure, the import and export of the pump can be installed in the pipeline as any position and any direction, installation and maintenance is very convenient. 3, smooth operation, safe and reliable: Motor shaft and pump shaft for the coaxial straight, high concentricity, stable operation, safe and reliable. 4, stainless steel sleeve: shaft sealing position is relatively easy to rust, direct-coupled pump shaft once corroded, easy to cause mechanical seal failure. ISG pumps are fitted with stainless steel bushings to prevent rusting, improve shaft life and reduce operating and maintenance costs. 5, Bearing: pump equipped with motor, Y (Y2) 280 below the shaft end bearings (including Y180 the following blade end bearings) with closed bearings, normal use, maintenance-free motor bearings. 6, mechanical seal: mechanical seal base member is generally used rubber bellows structure, the traditional mechanical seal shaft seal by the O-ring seal into two parts of the rubber seal, sealing water in the media to improve the sealing effect. Third, the working conditions of flow: 2 ~ 1400m3 / h Head: 5 ~ 130m System maximum working pressure: ≤ 1.6MPa Operating temperature: Normal DFG -15 ℃ ~ +80 ℃ hot water type DFRG +80 ℃ ~ 105 ℃ Insulation class: Class B or Class F Protection class: IP44 or IP54 Ambient temperature: ≤ + 40 ℃ Motor type: Y or Y2
