Piping pump selection basis, should be based on process, water supply and drainage requirements, to be considered from five aspects, namely 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. 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, taking into account the normal flow, in the absence of maximum flow, 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. 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 cycles 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. FG-type pipeline centrifugal pump This series pump 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 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. DFRG Centrifugal Pump This series pump is based on the international ISO2858 standards, and the latest hydraulic model, at the same time with reference to the development of international standards 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.

PVA sponge polishing wheel adopts special synthetic resin to enhance its wear resistance
And the grinding force, by the existence of special air hole, can quickly eliminate the dust, no packing and hair
Heat phenomenon, avoid heat burn workpiece, suitable for long time grinding work. The binder is soft and slow
Impact, no deep blemishes on the grinding surface.
Use of PVA grinding wheel :1. It is easy to heat up when using general sand flower and sand cloth
Used for grinding stainless steel, aluminum, copper, iron, wood, gemstone, marble, glass, graphite
Products, urea products and leather, etc. PVA sponge grinding wheel is the most suitable. In addition, it can be eliminated
Burr, dirt, rust, etc.
2. Using PVA sponge grinding wheel, you can get beautiful grinding surface and saving after a short time of work
Omitted number of projects. For example, all kinds of metal grinding, copper mixing cylinder (centerless polishing), watchcase,
Grinding of watchband, gemstone and marble before plating or polishing.
