Concentrated sulfuric acid magnetic pump parameter requirements

　　The parameter requirements of concentrated sulfuric acid magnetic pump involve many aspects, mainly including flow rate, head, using temperature, material specific gravity, containing particles condition, as well as pump material and motor power. The following is a detailed summary of these parameter requirements:

　　First, the basic parameters

　　Flow (Q):

　　Indicates the amount of liquid conveyed by the pump in a unit of time, the unit is usually m³/h. The specific value is determined according to the actual application requirements.

　　Head (H):

　　Indicates that the pump can lift the height of the liquid, the unit is usually m. The selection of head should be determined according to the conveying distance and height difference.

　　Second, the use of conditions

　　Using temperature(T):

　　Concentrated sulfuric acid has different physical properties at different temperatures, so it is necessary to select suitable pump body materials and seals according to the actual use temperature of concentrated sulfuric acid. Usually, the operating temperature of magnetic pumps should be within a certain range, which may lead to degradation or damage of the pump.

　　Material specific gravity (ρ):

　　Concentrated sulfuric acid has a large specific gravity, generally around 1.84. According to the specific gravity of the material, it is necessary to select the appropriate motor power to ensure the normal operation of the pump. When the specific gravity of the material is too large, it may be necessary to choose a pump with a high head and cut through the impeller to meet the conveying requirements.

　　Containing particles:

　　Concentrated sulfuric acid usually does not contain solid particles, but if there are impurities or solid particles exist, need to consider the pump's wear resistance and filtration measures.

　　Material of pump body

　　Material of overflow parts: According to the corrosive property of concentrated sulfuric acid, corrosion-resistant material should be chosen as the overflow parts of the pump. Common materials include fluorine plastic (such as F46), stainless steel and so on. These materials can resist the corrosion of concentrated sulfuric acid to ensure the long-term stable operation of the pump.

　　Fourth, the motor power

　　Motor power needs to be selected according to the specific gravity of the transport medium, flow and head to determine. When the specific gravity of the material is larger, the motor power needs to be increased accordingly. At the same time, also need to consider the efficiency of the motor and energy consumption and other factors, in order to select cost-effective motor.

　　V. Other parameters

　　Rotation speed (n): The rotation speed of magnetic pump is usually high, but the specific value should be determined according to the pump design and production process. The selection of rotational speed needs to consider the efficiency of the pump, noise and vibration and other factors.

　　Caliber (Ø): The caliber of the pump's inlet and outlet should be determined according to the size of the conveying pipeline and flow requirements. Ensure that the inlet and outlet of the pump are well aligned with the pipeline to reduce fluid resistance.
