Magnetic pump the correct selection method
First, the performance parameters of the magnetic pump Magnetic pump performance parameters Pump Type Flow m³ / h Head m Temperature ℃ Motor Power KW Remarks Metal magnetic pump 0.2 ~ 200 1.2 ~ 125 -20 ~ 110 ≤ 75 Medium particle diameter should be 0.2mm non Metal magnetic pump 0.2 ~ 30 0.2 ~ 40 ≤ 7.5 Second, the magnetic pump selection steps Based on the current status of domestic production of magnetic pumps and magnetic materials, the development of sliding bearings, in order to ensure the quality of the project, the selection of magnetic pump Can refer to the following steps. 1, the power of less than 10KW pump, use a magnetic pump to ensure the use of results. 2, when the pump shaft power is greater than 10KW or the medium temperature is higher than 100 ℃, the selection of domestic magnetic pump should be carefully handled, deal with the magnet material, bearing material structure to be limited, if necessary, should be used shielding pump. 3, the current domestic magnetic pump manufacturers are generally medium and small plants, development and research and development tools is weak. For the pump beyond the range of product parameters, it is generally not suitable for the manufacturer to develop or develop the pump to ensure the quality and progress of the project. Domestic main magnetic pump manufacturers and their products in Table 1-1. 4, Magnet material is related to the quality of the pump life, reliability and price, the order should be clear magnetic materials, suppliers and manufacturers of its performance indicators. Responding to the material and life of plain bearings should also be made clear.
