RICITE Technology bravely becomes a trendsetter of the times, striving to explore the path of magnetic levitation magnetic pumps
In 2022, a new outbreak of COVID-19 occurred suddenly, and the economy faced a severe test, with many enterprises facing enormous pressure. However, RICITE Technology bucked the trend and achieved a significant increase in production and sales year-on-year. Key products such as magnetic pumps, shielded pumps, pneumatic diaphragm pumps, and chemical pumps ranked first in sales, receiving unanimous praise from customers. Achievements belong to the past, innovation wins the future. RICITE Technology is well aware that only by continuously innovating and starting businesses to meet the needs of the market in the new era can it continuously catch up with and surpass the industry. Therefore, in 2022, after strict design verification, extensive market research, and production testing, RICITE Technology has decided to carry out the design, research, and production of a new generation (fifth generation) magnetic pump - magnetic levitation bearing magnetic pump. We dare to be the first and be the trendsetter of the times, actively explore the path of magnetic levitation magnetic pump research and development, and achieve new breakthroughs. In recent years, China has made great progress in the research and development of Maglev. The Maglev has been successfully tested, and the speed can reach nearly 600 km/h. The magnetic levitation line has been successfully tested on the "Zhonghua 6" lightweight suspension rail magnetic levitation technology verification vehicle. A permanent magnetic levitation line with a speed of up to 536 kilometers per hour will be built in Dalian, indicating that magnetic levitation technology has shifted from military, aerospace, and other fields to industrial and civilian industries. The dream of magnetic levitation has already come true. /Magnetic levitation science popularization/ There are currently three types of magnetic levitation in the world: One is the constant conductive magnetic levitation represented by Germany; The second is the superconducting electric maglev represented by Japan, both of which require electricity to generate maglev power; The third type is China's permanent magnet suspension, which utilizes special permanent magnet materials and does not require any other power support. Because the vehicle body is not in contact with the track, there is no friction, no bumps or vibrations will occur, and no sound will be emitted. Only when the vehicle speed reaches a certain level, passengers will hear some sound generated by friction with the air. Magnetic motors have high traction, low noise, and good environmental protection effects. Compared with the synchronous linear motor drive technology commonly used in foreign maglev systems, the magnetic motor drive technology can save about 50% of energy and save construction costs of 20 million to 40 million RMB/kilometer. It can be seen that our company has caught up with and surpassed the Vanguard International Semiconductor Corporation level in the field of Maglev, reaching the world level. Magnetic levitation technology has broad application prospects in various fields, including aerospace, nuclear industry, chemical industry, military industry, etc. So, is there a place for magnetic levitation technology in the field of magnetic pumps? The answer is yes, the magnetic levitation magnetic pump is a good application. -Character events- Professor Li Guo Kun, a magnetic circuit expert, assisted in the research and development of Richter Technology's magnetic levitation magnetic pump. Recently, Professor Li Kun, the founder of Li's push-pull magnetic circuit theory, and his team came to Richter Technology (Zhejiang) Co., Ltd. to assist in the research and development of Richter Technology's magnetic levitation magnetic pump. After theoretical research and on-site investigation, Professor Li is very confident in the production and research and development capabilities of Richter Technology. Introduction: Professor Li Guokun For over 40 years, I have been engaged in the research and development of magnetic mechanics theory and high-tech. In the past 20 years, I have mainly been engaged in the development of rare earth magnetic circuits and rare earth magnetic devices. He has made outstanding and creative contributions in such high-tech fields as magnetic circuit, magnetic transmission, magnetic seal, magnetic suspension, magnetic pump, magnetic beneficiation, magnetic iron removal, magnetic Level sensor, energy-saving large electromagnet, etc. In 1979, he invented the "pull push magnetic circuit" theory, which has always been at the forefront and is known as the "Li's pull push theory". Received the third prize of the National Invention Award and made first-class contributions to the Ministry of Aerospace Science. This invention has been widely used in multiple high-tech fields such as satellites, as well as in various civilian industries such as petrochemical, vacuum, and electromechanical industries. Magnetic levitation magnetic pumps are a new trend in the pump valve industry, but they have also encountered many technical difficulties. Although facing numerous difficulties, the full assistance of professionals has brought motivation and confidence to the people of Richter Technology. We will tirelessly invest our energy in the research and design of magnetic levitation magnetic pumps. Although there is a long and arduous task ahead, it is imperative -Design Principles- Utilizing magnetic field force to non-contact suspend the rotating shaft, revolutionizing the traditional magnetic pump support technology. As is well known, the sliding bearings used to support the impeller and rotor on magnetic pumps, as well as the thrust rings used to withstand axial force, rely on the transported medium for lubrication and cooling. If the circulation system malfunctions, the pump will be quickly damaged, and in severe cases, serious accidents will occur. Magnetic levitation bearing is a new type of bearing that utilizes electromagnetic force to stabilize the rotor and control the axis position through a control system. Simply put, it means suspending the pump shaft without any contact, friction or wear, requiring no lubrication, and increasing the speed, thereby significantly improving pump efficiency, reducing energy consumption, and extending service life. It has advantages that other magnetic pumps cannot compare, greatly improving customer production efficiency and increasing production capacity. /Basic Principles/ Magnetic levitation bearings are bearings that use magnetic field forces to non-contact suspend the rotating shaft. Contactless can avoid mechanical wear, reduce energy consumption, and reduce noise, thus having the advantages of maintenance free, high speed, high accuracy, and good dynamic characteristics. Its power consumption is about 1/10-1/100 of that of ordinary sliding bearings. The electronic control system can control the position of the shaft, adjust the damping and stiffness of the bearings, and ensure good dynamic stability of the shaft sleeve. According to the suspension method, magnetic levitation bearings can be divided into passive magnetic levitation bearings (also known as passive magnetic levitation bearings) and active magnetic levitation bearings (also known as active magnetic levitation bearings). A bearing that uses only permanent magnets or superconductors for suspension is called a passive magnetic levitation bearing; The bearing that generates electromagnetic force through the power supply to suspend it is called an active magnetic levitation bearing. The permanent magnet magnetic levitation bearing has a simple structure, low cost, and reliable use, but its stiffness is low, it cannot be stable in both axial and radial directions, and it will leave a coordinate instability; Active magnetic levitation bearings have advantages such as high stiffness and stable operation, but they must be equipped with control systems. Therefore, the combination of permanent magnetic levitation bearings and active magnetic levitation bearing pumps is a very valuable design solution for magnetic levitation pumps. /Structural design/ The design of traditional magnetic pumps uses sliding bearings and shaft sleeves to support the weight of the shaft sleeve, impeller, and pump shaft. When thrust rings are used to withstand the axial thrust of the impeller, sliding bearings, shaft sleeves, and thrust rings are referred to as interchangeable parts and are key components for the service life of magnetic pumps. For a long time, although designers have continuously studied, improved, and improved the materials used for these friction pairs, no matter what material pairing is used, there is inevitably mechanical friction during high-speed operation, which limits the service life of the pump. So, only when this friction does not exist can the service life of the magnetic pump be greatly improved. Magnetic levitation magnetic pump is a new type of magnetic pump developed based on the theory of magnetic levitation without contact support. The emergence of magnetic levitation magnetic pump has solved the above technical problems. /Electromagnetic bearing/ The electromagnetic bearing adopts the design of repulsive electromagnetic bearings, and the body is composed of circular ferromagnetic laminations. The circumferential winding coil generates electromagnetic force after being energized. The inner circular side wall is equipped with a displacement sensor to detect the deviation signal of the shaft sleeve; There is an interface on the surface of the outer circle, which sends the detected deviation signal of the shaft sleeve to the external control device through the interface. The power amplifier controls the current in the magnet, thereby generating changes in electromagnetic force to suspend the shaft sleeve in the specified position.. Considering the corrosiveness of the conveying medium, the electromagnetic bearing is arranged and packaged through a stainless steel sleeve after assembly, with a wedge surface on the outer circle to fix the electromagnetic bearing on the bearing seat of the magnetic pump. /Permanent magnet shaft sleeve/ The permanent magnet shaft sleeve is made of a ring shaped strong magnetic permanent magnet material neodymium iron boron, which is radially magnetized and mounted on a stainless steel permanent magnet shaft sleeve seat. After assembly, its outer circle is encapsulated through a sleeve. This component is installed on the pump shaft and transmits power through a key located on the pump shaft to synchronize its rotation with the pump shaft. After final assembly, there is a radial gap of 1-1.5mm between the electromagnetic bearing and the permanent magnet shaft sleeve. Based on the principle of isotropic repulsion, the high-speed rotating pump shaft is suspended in a set position using the repulsive force of its surface magnetic field, and monitored through an external controller. The circulating system inside the pump is only used to remove eddy current heat from the metal isolation sleeve. /Permanent magnet thrust ring/ Traditional designs use thrust rings to balance the axial force generated by the impeller on a magnetic pump. The thrust ring on the magnetic levitation magnetic pump is a permanent magnet thrust ring structure, which is composed of a strong permanent magnet material neodymium iron boron that is radially magnetized and embedded on a stainless steel seat. After assembly, its surface is then packaged as a whole through a circular stainless steel sleeve. There is a gap of 1.5mm between the permanent magnet thrust ring and the electromagnetic bearing. Therefore, the ideal path for the research and development of magnetic levitation pumps is to cooperate with permanent magnet magnetic bearings and active magnetic bearing pumps, and to scientifically and reasonably assemble permanent magnet material accessories. -Looking forward to the future- It will certainly drive the new trend of magnetic pump and open up a Xintiandi Adhering to conventions can only stay put, and innovation can keep up with the times. The people of Richter Technology deeply understand the principles behind it, so they are fully committed to promoting the research and production of magnetic levitation magnetic pumps and bravely becoming trendsetters of the times. It is believed that the launch of Richter Technology's magnetic levitation magnetic pump will drive the new trend of magnetic pump and open up a new world。
FAQS

How much temperature can high-temperature canned pumps withstand?
High temperature shielded pump is a high-temperature liquid pump that can transport hot oil and hot water, consisting of two parts. The pump body and impeller form a high-temperature chamber, while the stator and rotor form a low-temperature chamber. Although the liquid in these two rooms is the same, the temperature is different. Due to the obstruction caused by the connecting body and shaft sleeve, the liquid in the two rooms is almost not mixed together. In addition, the end face of the connecting body has a small contact area with the motor, thereby reducing the heat transfer from the pump chamber to the motor chamber. High temperature liquid usually refers to a liquid that is higher than the specified motor inlet liquid and has a high temperature below 350 ℃, and the liquid itself does not contain particles, has a low melting point, etc. The high-temperature separation type all has a connecting body (also known as a heat shield), a heat exchanger, and a cooling jacket. Although the temperature of the conveyed medium is higher than the specified motor inlet liquid * high temperature, due to the heat shield effect of the connecting body and the cooling effect of the exchanger, the temperature of the liquid entering the motor is lower than the specified motor inlet liquid * high temperature. The cooling of this pump motor and lubrication of the bearings are carried out by a secondary impeller installed at the rear of the rotor, which forcibly circulates the circulating fluid of the motor. 2023-06-19 -
How to choose a high-temperature magnetic pump? What is suitable is good.
According to incomplete market research statistics, less than 70% of users know how to choose and purchase high-temperature magnetic pumps correctly. Due to insufficient purchasing experience and insufficient understanding of the product characteristics of high-temperature magnetic pumps, even a large number of buyers only purchase according to the specified standards of the enterprise, without customizing products according to their own needs, making it difficult to purchase high-temperature magnetic pumps effectively. In fact, the production technology of pumps is constantly changing, and there are also slight differences in product performance. If a company can master more skills, it not only needs to understand its own needs, but also needs to understand the other party's products. Remember the following points to help you choose products correctly. Self positioning High temperature magnetic pumps have a wide range of applications, with clear self positioning and careful selection of models based on medium and operating conditions. Generally speaking, different media require different pump body parameters. For example, when conveying flammable, explosive or toxic media, reliable shaft seals or leak free pumps can be selected. If there is a need for corrosion resistance, it is also necessary to indicate in advance. It is best to clearly list the concentration, viscosity, temperature, etc. of the media, so that manufacturers can customize them to meet user needs. Pump parameters Different pump types have different parameters, and high-temperature magnetic pumps can also be divided into many different models. Therefore, buyers need to have a detailed understanding of the flow, temperature, pressure and other parameters of the device, and choose products with appropriate parameters based on their usage in order to truly unleash the value of the product. Cost issues For enterprises, whether it is purchasing expenses or maintenance expenses, they are all cost issues of purchasing pumps. We cannot only focus on the discounted prices in front of us, but also need to examine the endurance, service life, maintenance and other issues of high-temperature magnetic pumps in subsequent work, in order to effectively save expenses. RICITE has solved the technical challenges of industrial application of magnetic pump drive technology! Magnetic circuit design and industrial applications with large magnetic gaps. Material selection of flow components during the transportation of highly corrosive and high viscosity media.

What is the reason for the failure of the magnetic pump?
The failure of magnetic pumps may be caused by various reasons, but the main ones are as follows: Cavitation, medium, damage to internal parts (sliding bearings, isolation sleeves), production accuracy, motor failure, incorrect operation, demagnetization, etc. Understanding the causes of magnetic pump failure can lead to the occurrence of the malfunction. Xiaorui will summarize the reasons for the magnetic pump failure: 1. Cavitation leads to the failure of magnetic pumps: The main reasons for cavitation in magnetic pumps include: high resistance of the pump inlet pipe, excessive gas phase of the conveying medium, insufficient pump filling, and insufficient energy head at the pump inlet. Cavitation is also a common cause of pump failure, which poses great harm to the pump. When cavitation occurs, the pump vibrates violently and the balance is severely damaged, leading to damage to pump bearings, rotors, or impellers and other components. 2. Damaged isolation sleeve: The magnetic coupling of the magnetic pump is cooled by the medium conveyed by the pump. If there are hard particles in the conveyed medium, it is easy to cause scratches or punctures on the isolation sleeve. Improper maintenance methods may also cause damage to the isolation sleeve. 3. Lack of medium or low medium flow rate: This situation can cause dry friction between the rotor spindle and the stable bearing, resulting in the burning of the bearing. The conveying medium provides lubrication and cooling for the sliding bearing of the magnetic pump. If the inlet or outlet valves are not opened, the sliding bearing will be damaged due to high temperature due to the lack of conveying medium lubrication and cooling. 4. Magnetic pump demagnetization: The motor driven pump emits heat during transportation, and the same applies to magnetic pumps. If the flow rate is below the standard value for a long time during transportation, or if unexpected circumstances cause idling, it will gradually cause the pump chamber temperature to rise. When the temperature exceeds the heat resistance limit of the pump type, demagnetization will occur. To avoid this fault, it is necessary to arrange a dedicated person to monitor the transportation status of the pump in real time during use, avoid idling, and ensure that the medium temperature does not exceed the pump type standard. If high-temperature medium needs to be transported, a specialized high-temperature shielded pump should be selected. 5. Internal abnormal noise: If there is a decrease in flow, it is necessary to consider whether the internal components are abnormal. Nowadays, some small manufacturers in the market may have poor quality when producing magnetic pumps, such as asymmetric unit axes, swing exceeding allowable values, and poor mechanical strength and stiffness of components. 6. Motor failure: Generally, motor problems are caused by current and voltage issues. The current value of the motor can be measured and the voltage can be checked to see if it meets the corresponding standards. The motor's own parameters such as speed, direction, and current can also be checked to see if they are within the standard values. If they are normal, it is considered whether there is a problem with the internal components of the motor, causing magnetic imbalance and causing systemic faults. Sometimes, when the motor is accompanied by abnormal vibrations and noise, it can be checked whether the magnetic center of the stator and rotor is consistent, and whether the air gap difference in each direction is within the allowable deviation value. If * *, replace the motor with a new one. 2023-06-19
