How to select a corrosion-resistant magnetic pump?

　　On how to choose a good corrosion-resistant magnetic pump, from the material, performance elements to discern the corrosion-resistant magnetic pump, according to the different materials, but also affects the versatility of its performance.

　　Therefore, to choose the right corrosion-resistant magnetic pump first need to consider its material, to see whether it is suitable for the product demand, and secondly, its performance characteristics are also what we need to consider, of course, in the energy-saving emission reduction nowadays, its energy-saving is also an indispensable element to consider.

　　So how to choose the corrosion resistant magnetic pump?

　　1, corrosion-resistant magnetic pump material selection

　　Corrosion-resistant magnetic pump is acid-resistant principle lies mainly in the pump material, the general use of non-metallic materials as the pump flow parts materials, such as “polyethylene, polypropylene, polyperfluoroethylene propylene, etc.”, of which the polyperfluoroethylene propylene is one of the good acid-resistant material, basically can withstand the corrosion of any acidic medium, known as the plastic king.

　　Of course, the selection of specific materials should also be based on the specific application environment, such as plating industry corrosion-resistant magnetic pumps are mainly used to transmit a variety of acidic and alkaline liquid; in the PBC industry used in PCB etching equipment; in the environmental protection industry used in waste gas, waste water treatment. Then the material of the pump has FRPP, CPVC, PVDF, PPS, etc. to choose from.

　　2, according to the process parameters to choose

　　Process parameters are an important basis for the selection of permanent magnet drive magnetic pumps, should be carefully determined according to the process and operational changes in the range. Such as flow, head is one of the important process parameters for pump selection, which is directly related to the production capacity and conveying capacity of the whole device.

　　1. Flow Q flow refers to the production of process equipment, the pump is required to transport the amount of media. Process personnel should give the normal minimum and greater flow. Pump data sheet often only gives the normal flow and rated flow. Selection of fluorine lined magnetic pump, the rated flow rate is not less than the device's greater flow rate, or take the normal flow rate of 1.1 ~ 1.15 times.

　　2. Head H value of the head value required by the process device, also known as the calculated head. General requirements for the pump rated head for the device required head 1.05 ~ 1.1 times.

　　3. Inlet and outlet pressure inlet and outlet pressure refers to the pump inlet and outlet flange pressure. The size of the inlet and outlet pressure affects the shell and shaft seal (isolation sleeve) pressure requirements.

　　4. Temperature T refers to the pump's inlet medium temperature, generally should be given to the chemical magnetic pump of the inlet medium of the normal, lower and higher temperature values.

　　5. device corrosion allowance is also known as effective corrosion allowance.

　　6. operation state operation state is divided into continuous operation and intermittent operation of two kinds.

　　3, performance and energy saving at the same time

　　Generally referred to the selection of corrosion-resistant magnetic pumps, most people first think of the pump material, in fact, in addition to the material, the power consumption of the device that is whether to save energy is equally important.

　　China's acid and alkali pump power consumption accounts for more than 21% of the national power consumption. Therefore, vigorously reduce the acid and alkali pump energy consumption, has great significance.

　　Specifically, the following aspects need to be considered:

　　1, the equipment should have good anti-vapor corrosion performance, smooth operation, long life;.

　　2, excellent performance of the pump must meet the requirements of the use of flow and head, so that both power saving and not easy to damage the machine parts;.

　　3, corrosion-resistant magnetic pumps should be small, light weight, cheap, but also has good characteristics and high efficiency.

　　Comprehensive view, an excellent performance of the corrosion-resistant magnetic pump to suit his operating environment, at the same time to save energy, durability, purchase can provide detailed data to the corrosion-resistant magnetic pump manufacturers, manufacturers to provide you with the most reasonable selection of corrosion-resistant magnetic pump recommendations.
