Magnetic circulation pump is a special pump, which adopts magnetic drive technology to achieve non-contact transmission, with high efficiency, no leakage, low noise, low maintenance and other advantages, widely used in chemical, pharmaceutical, food, environmental protection and other fields. The following will introduce the structure, working principle, characteristics and selection precautions of the magnetic circulation pump in detail.
First, the structure of the magnetic circulation pump.
The magnetic circulation pump is mainly composed of a pump body, an impeller, a magnetic drive, a bearing body and a sealing ring. Among them, the pump body is the shell of the magnetic circulation pump, which is usually made of stainless steel or cast iron; The impeller is the core component of the magnetic circulation pump, which is composed of magnetic materials and permeable materials, which can generate magnetic fields; The magnetic drive is a key component to achieve non-contact transmission, which is mainly composed of permanent magnets and electromagnets; The bearing body is an important part of supporting the impeller and bearing frame, and high-strength ceramic bearings are usually used; Seals are an important part to prevent media leakage and are usually made of rubber or fluoroelastomer materials.
Second, the working principle of the magnetic circulation pump.
The working principle of the magnetic circulation pump is mainly to use magnetic drive technology to achieve non-contact transmission. When the motor drives the magnetic drive to rotate, the magnetic field force is transmitted to the impeller through the bearing body, so that the impeller produces a rotational moment, thereby driving the medium to rotate. At the same time, the sealing ring prevents the leakage of the medium and ensures that the medium can be fully circulated.
3. Characteristics of magnetic circulating pump.
1.High efficiency: The magnetic circulation pump uses magnetic drive technology to achieve non-contact transmission, reducing friction and energy loss, so it has high efficiency.
2.No leakage: Because the sealing ring of the magnetic circulation pump can prevent the leakage of the medium, it has good sealing performance and will not cause pollution to the environment.
3.Low noise: The magnetic circulation pump runs smoothly and has low noise, which will not cause noise pollution to personnel and the environment.
4.Low maintenance: The structure of the magnetic circulation pump is simple, easy to maintain and maintain, reducing the maintenance workload and cost.
Fourth, the selection of magnetic circulation pump precautions.
1.Determine the conveying medium: When choosing a magnetic circulation pump, the first thing to do is to determine the medium that needs to be conveyed, such as liquid, gas or special medium. At the same time, it is necessary to understand the viscosity, corrosiveness, solid particles and other physical parameters of the medium, so as to select the appropriate pump type and material.
2.Determine the flow rate and head: Determine the flow rate and head and other parameters according to the actual needs. Flow refers to the volume of medium transported per unit of time, and head refers to the height at which the pump can lift the medium. When selecting a magnetic circulation pump, it is necessary to select the model according to the actual needs to ensure that the parameters of the pump can meet the actual needs.
3.Determine the form and material of the pump: Select the form and material of the pump according to the actual needs. Magnetic circulation pumps are available in a variety of forms and materials, such as stainless steel, cast iron, ceramic, etc. When selecting, it is necessary to consider factors such as the corrosiveness and wear resistance of the medium, as well as factors such as the environment and budget of use.
4.Choose the right drive method: The magnetic circulation pump has a variety of drive methods to choose from, such as motor drive, hydraulic drive, etc. When choosing, it is necessary to choose the appropriate drive mode according to the actual needs to ensure the smooth operation and efficient transmission of the pump.
5.Consider energy saving and environmental protection: When choosing a magnetic circulation pump, energy saving and environmental protection factors should be considered. Whenever possible, choose pump types and drives that are efficient and have low energy consumption, while choosing materials and components such as seals that have a low environmental impact.
In short, when selecting a magnetic circulating pump, it is necessary to determine the structural form and materials according to the actual needs, and comprehensively consider the parameters such as flow rate and head, as well as energy saving and environmental protection. At the same time, it is necessary to understand the characteristics and precautions for the use of magnetic circulation pumps, so as to better play its advantages and prolong the service life.
