Pipe pump selection pump selection basis, should be based on process, water supply and drainage requirements, to be considered from five aspects, both liquid delivery capacity, device lift, liquid properties, piping layout and operating conditions.
1, the flow rate is one of the important performance of the election pump data, which is directly related to the entire plant's production capacity and delivery capacity. Centrifugal pumps, such as the design process can be calculated in the pump normal, minimum, maximum three kinds of flow. Select the pump, based on the maximum flow, take into account the normal flow, in the absence of the maximum flow, it is usually desirable 1.1 times the normal flow as the maximum flow.
2, the lift system required for installation of the pump is another important performance data, generally to enlarge the 5% -10% head lift to choose.
3, the liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, the physical properties of the temperature c density d, viscosity u, medium particle diameter and gas content, etc., which involves the system lift, effective gas Erosion margin calculation and the type of suitable pump: Chemical nature, mainly refers to the liquid medium chemical corrosion and toxicity, is the selection of pump materials and choose an important basis for the type of shaft seal.
4, the installation of piping system conditions refers to the liquid from the height of the liquid into the liquid distance to the suction side such as the lowest level, the highest level of the discharge side of some data and pipe specifications and length, material, pipe specifications, the number , Etc., in order to carry out the Department of combing head calculation and NPSH check.
5, the operating conditions are many, such as the operation of the liquid T saturated steam P, suction side pressure PS (absolute), the discharge side of the tank pressure PZ, altitude, ambient temperature operation is gap or continuous, the pump position is fixed Or removable.
ISG single-stage pipeline pump This series of pumps for industrial and urban water supply and drainage, high-rise building water tower pressurized water supply, fire pressurization, pipeline pressurization, long-distance water supply, heating and cooling cycle and other occasions. The series of pumps with smooth operation, reliable, low noise, the use of a wide range of advantages, is an ideal single-stage single-suction centrifugal pipeline booster pump.
ISW Horizontal Pipeline Centrifugal Pump This series of pumps is based on the international ISO2858 standards, and the latest hydraulic model, at the same time with reference to the relevant international standards of research and design into a series of SG-series pipeline pump alternative. Its adopted technical standards, performance parameters, test methods and so on are all effectively adopted ISO international standards related to IS centrifugal pumps. It has basically the same performance parameters as IS centrifugal pumps, and its performance indexes all meet the design requirements.
ISG, IRG, IHG, YG Vertical Pipeline Centrifugal Pump This series of pump is based on the international ISO2858 standards and the latest hydraulic model, with reference to the relevant international standards of research and design into a series of SG-series pipeline pump alternative. Its adopted technical standards, performance parameters, test methods and so on are all effectively adopted ISO international standards related to IS centrifugal pumps.
