Pipeline pump model selection
Pipe pump model selection basis, should be based on process, water supply and drainage requirements, to be considered from five aspects, namely liquid delivery capacity, the device head, the nature of the liquid, piping layout and operating conditions.
1. The flow rate is one of the important performance data of pump selection, it is directly related to the entire plant's production capacity and delivery capacity. Such as the design process can be calculated in the pump normal, minimum, maximum three kinds of flow.
2. Installation system required lift or pressure is to choose another important performance pipeline pump performance data, generally to enlarge 5% -10% head lift to choose.
3. Liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, the physical properties of temperature c density d, viscosity u, medium particle diameter and gas content, etc., which involves the system lift, effective gas Erosion allowance calculation and the type of suitable pump: Chemical nature, mainly refers to the chemical corrosivity of liquid medium, is the choice of pump material and the choice of an important basis for the type of shaft seal.
4. The piping system installation conditions refers to the liquid from the height of the liquid from the liquid to the suction side suction side of the lowest level, the discharge side of the highest level of some data and pipe specifications and the length of the material, pipe specifications, the number , Etc., in order to carry out the Department of combing head calculation and NPSH check.
This type of pipe centrifugal pump 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 pressure booster pump.
ISG Centrifugal Pump This series of pumps 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 SG-pipe 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.
IRG Hot Water Pipeline Pump This series of hot water pipeline pump is based on the international ISO2858 standard, at the same time with reference to the relevant international standards of research and design into a SG- pipe pump alternative. The adopted technical standards, performance parameters and test methods are all effectively adopted the ISO international standards related to IS centrifugal pumps. Equipped with high temperature resistant mechanical seals capable of withstanding 120 ℃ hot water, its performance indicators all meet the design requirements.
