Vertical Pipeline Centrifugal Pump Structure I. Product Overview ISG series single-stage single suction vertical pipe centrifugal pump is a direct-coupled pipe pump structure, the impeller is mounted on the motor shaft, with stable operation Simple structure, easy maintenance and repair, easy installation And covers an area of ​​province (compared with the ordinary horizontal pump than the floor area savings of more than 30%) and other characteristics; products meet the GB / T5657-1994 "centrifugal pump technical conditions (III)" standard; transportable medium temperature does not exceed 105 ℃ The water or other physical and chemical properties similar to other liquids in water. Second, the product features 1, energy-efficient: CFD CFD, analyze and calculate the pump pressure distribution and speed distribution, optimize the pump flow channel design, to ensure that the pump has an efficient hydraulic shape line to improve the pump efficiency. 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 Flow: 2 ~ 1400m3 / h Head: 5 ~ 130m System maximum working pressure: ≤ 1
