The magnetic centrifugal pump is a magnetically coupled centrifugal pump in which the drive motor and the actual pump are mechanically separated.
The pump adopts non-contact magnetic drive. This structure eliminates the shaft seal required by traditional centrifugal pumps, which often causes leakage problems. The pump casing is sealed with a magnetic centrifugal pump structure, which has high operating safety and long service life.
Therefore, the basic feature of these centrifugal pumps is a sealless design that does not allow leakage.
The material used in the magnetic centrifugal pump is characterized by high chemical resistance and heat resistance, thus ensuring a long service life.

When the medium is hydrocarbon or oil, the temperature rise in the annulus area can be maintained at 5-8°C. Sliding bearing The material of the sliding bearing of magnetic pump includes impregnated graphite, filled PTFE, engineering ceramics and so on. Because engineering ceramics have good heat resistance, corrosion resistance, and friction resistance, the sliding bearings of magnetic pumps are mostly made of engineering ceramics. Because engineering ceramics are very brittle and have a small expansion coefficient, the bearing clearance must not be too small to avoid shaft hung accidents. Since the sliding bearing of the magnetic pump is lubricated by the conveyed medium, different materials should be used to make the bearings according to different media and operating conditions. 5. Protection measures When the driven part of the magnetic drive is running under overload or the rotor is stuck, the main and driven parts of the magnetic drive will automatically slip off to protect the pump. At this time, the permanent magnet on the magnetic actuator will produce eddy loss and magnetic loss under the action of the alternating magnetic field of the active rotor, which will cause the temperature of the permanent magnet to rise and the magnetic actuator to slip and fail.
Magnetic drive pumps have a particular sealless design that is suitable to pump corrosive and dangerous liquids thanks to the high chemical resistance and absence of leakage and emissions.
Magnetic gearbox centrifugal water pumps (collectively referred to as magnetic pumps) are based on the principle of magnetic kinematics. When the motor promotes the overall rotation of the outer stator (ie, the outer magnetic steel), the electric field turns over the guard sleeve to promote the inner stator (ie, the inner Magnet) The total distance and the wind wheel rotate at the same time. Because the organic matter is open in the uniform motion prevention cover, the purpose of pumping the organic matter without leakage is exceeded, and the shaft seal of the gear drive pump is prevented from leaking. Leaky, low-carbon and environmentally friendly industrial pumps. In addition, magnetic pumps are all used in the chemical process to prevent running, emitting, dripping, and leaking, eliminate environmental pollution, and create a “leak-free industrial zone” and a “leak-free factory” to maintain safety and the hope of civilian production.
The PP magnetic drive pump is used in the production process of petroleum, chemical, pharmaceutical, knitting factories, electric ferry, meat food, ecological environmental protection and other enterprises to transport toxic liquids that can contain iron and sludge. It is especially suitable for flammable, combustible, volatile, and hazardous materials. And transportation of precious liquids.
In the petrochemical manufacturing industry, more and more manufacturers require a leak-free process environment for the organic matter they transport. In some unique places, such as the transportation of oil or particulate organic matter (such as wastewater treatment) , And in the chemical production process, it is more tightly focused on choosing the desired leak-free pump type. The magnetic gearbox high temperature multi-stage pump and the magnetic pump product series with mixed-liquid separation equipment solve the bottleneck of the development of high temperature (350°C) transportation and particulate organic matter that the basic magnetic pump cannot solve from the beginning to the end. It can immediately replace the gear-driven IH type Chemical pump. The magnetic pump has undergone long-term scale-up and continuous operation and tempering, and customers can firmly believe that they are using safe and reliable pumps.
The principle of gearbox The magnetic drive pump is a new type of pump that uses a structural design with a magnetic coupling to transmit torque without contact. When the motor promotes the rotation of the outer magnetic stator, the electromagnetic field promotes the inner magnetic stator and the wind wheel to rotate simultaneously. So beyond the purpose of pumping liquid, because the liquid is opened in the uniform movement of the guard sleeve, so it is this kind of closed, leak-free pump type.
Second, the characteristics of magnetic pump
The mechanical seal of the pump is cancelled, and the shortcomings of mechanical seal centrifugal water pump, dripping and leakage are completely eliminated. It is a leak-free factory. Because the pump’s overflow support is made of stainless steel, rubber and plastic products, it exceeds the purpose of corrosion resistance. The magnetic coupling of the pump and the pump casing are integrated, so the structure is compact, the maintenance is convenient and fast, and it is safe and energy-saving. The accidental running and venting couplings of the pump with magnets can protect the gearbox motor from overload.
Third, the use of magnetic pump
The magnetic pump is widely used in petroleum, chemical, pharmaceutical, electric ferry, ecological and environmental protection, water purification, film printing, civil defense and other enterprises to pump flammable, combustible, Hazardous and precious liquids are the hopeful pumps for creating non-leakage, low-carbon and environmentally friendly Wenmin Industrial Zones and Wenmin factories.
Four, magnetic pump work specifications
The strength of the magnetic pump to transport organic matter is not more than 1300kg/m3, and the viscosity is not more than 30×10-6m3/S, which may contain ferromagnetic and viscous liquids. The rated temperature of the basic magnetic drive pump is metal or F46 lining for the pump casing. The maximum operating temperature is 80°C and the rated water level is 1.6MPa; the operating temperature of the high-temperature magnetic pump is ≤350°C; for the pump casing made of silicon carbide, the higher The maximum temperature does not exceed 60℃, and the rated water level is 0.6MPa.
For liquids whose organic strength exceeds 1600kg/m3, a magnetic coupling can be designed. The bearing shaft of the magnetic pump is moistened and cooled with the organic matter being transported, and the magnetic drum pump is generally strictly prohibited to operate with full load.

The magnetic pump is suitable for installation in a horizontal orientation. Try not to bear a large net weight of water pressure. If the vertical installation must be carried out due to bad conditions or required restrictions, the motor must face upwards.
When the liquid side of the suction liquid is higher than the roller axis, the small part of the pipeline must be opened first; furthermore, if the liquid drawn is lower than the roller axis, a bottom valve must be arranged on the pipeline.
The PP magnetic drive pump should be inspected before work to see if the motor is operating smoothly and smoothly, if there is any abnormal noise, and if the firmware of each connection is loose, to ensure its safe operation.
Inquire whether the rotation position of the motor is the same as the marked brake.
After the motor is running, slowly and steadily open the drain valve, and after the facility enters the working attitude, adjust the drain valve to the required opening.
When the operation is to be terminated, the drain gate valve must be closed first, and then the suction pipe gate valve must be closed. The sequence cannot be mistaken.

The principle of 304 Air operated double diaphragm pump: A diaphragm is installed on the left and right sides of the aodd pump, which are connected by a central link. Compressed air enters the air distribution valve from the air inlet of the pump, and the compressed air is introduced into one cavity through the air distribution mechanism to push the diaphragm in the cavity to move, while the gas in the other cavity is discharged. Once the end of the stroke is reached, the air distribution mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm to move in the opposite direction, so that the two diaphragms reciprocate continuously and synchronously. In the figure, compressed air enters the valve to move the diaphragm to the right. The suction of the chamber causes the medium to flow in from the inlet, pushing the ball valve into the chamber, and the ball valve is blocked by suction; the medium in the chamber is squeezed. Push open the ball valve to flow out from the outlet, and at the same time lock the ball valve to prevent flow, so that the medium is continuously sucked in from the inlet and discharged from the outlet.
AODD pumps has two diaphragms, the compressed air come to the pump body to drive the pump in the constant action of sucking and releasing, so it can pump the liquids easily by this principle. Also it is very safe in dangerous environment since it has no electric motor.
Magnetic drive pumps are also called magnetic drive pumps, which are mainly made of engineering plastics or stainless steel. It plays an important role in machinery manufacturing. Friends who have used magnetic pumps for a long time know that magnetic pumps cannot be idling. So why can’t it be idling? Let us analyze it together today!
If you have ever understood the structure of magnetic pumps, then you must know that engineering plastic magnetic pumps have magnetic cylinders. What is the cooling of the magnetic cylinder? In fact, it is the medium relying on the magnetic pump. If the magnetic pump is in an idling condition, it will affect the normal state of the magnetic cylinder. It may cause the magnetic cylinder to lock up, and then cause the magnetic drive pump to work abnormally.
Restricted pump opening
For a magnetic pump to work, it must be lubricated. So, how to lubricate? It is actually the medium of the magnetic pump. If there is no magnetic pump medium, the magnetic pump will face the problem of difficulty in starting the pump.
High temperature demagnetization
The design and working principle of the magnetic pump have a certain connection with the magnetic field, so everyone must ensure the stability of the magnetic field. When the magnetic pump is idling, the temperature of its core components will increase, and high temperature will have a certain effect on the magnetic field, which will cause demagnetization. In addition, you have to know that the outer magnetic assembly and the inner magnetic assembly are the main components of the magnetic pump.
Why can’t the stainless steel magnetic pump run idling? After listening to the introduction of the editor, I think you should have a good idea. The above is the answer that the editor will bring to you today. No matter what kind of magnetic pump, no matter what kind of equipment, it has a certain service life. If you want to extend the service life, you must maintain and maintain it in time in daily life. So, how to maintain the magnetic pump? First, we must ensure that the magnetic pump is not cut off, and there can be no impurities in the magnetic pump. If the magnetic pump violates any of the above two taboos, it will cause certain damage to the bearing. The bearing is an important component of the magnetic drive pump. If it is affected, it will definitely shorten the life of the magnetic drive pump. Second, we need to pay attention to the proportion of liquid to be transported. If the proportion of liquid to be transported is too large, it will lead to insufficient head. In addition, damage to the impeller or a certain amount of air in the conveying medium can also cause this phenomenon. I hope everyone can try to avoid it. Third, we should always check the suction pipe of the magnetic pump to see if there is any air leakage. Especially when the magnetic pump can not pump liquid, pay more attention to this problem.

What is a magnetic pump A magnetic pump is a centrifugal pump with a magnetic coupling, also called a magnetic coupling pump, or a magnetic pump for short.
Working principle of magnetic pump The magnetic pump is in operation. It may cause leakage due to insufficient sealing of the isolation sleeve, so for safety reasons. Sometimes it is necessary to install a double-layer isolation shielded magnetic coupler with leakage display to transmit power to the centrifugal pump. It consists of an outer magnetic rotor and an inner magnetic rotor: the outer magnetic ball is fixedly connected to the motor bearing. The inner magnetic rotor is mounted on the bearing together with the impeller. Both the outer magnetic rotor and the inner magnetic rotor are equipped with permanent magnets, and they face each other with different magnetic poles. With the help of magnetism, the division attracts each other. When the outer magnet rotates and runs, the inner magnet rotor also runs synchronously (same speed). Centrifugal pumps with magnetic couplings are also called electromagnetic pumps or magnetic pumps, and their power can now reach about 400kW. As the torque that needs to be transmitted increases, the rotor angle between the shaft and the magnet also increases. If the torque that needs to be transmitted exceeds the maximum range (breaking torque). Then, the coupler will lose its function and the inner magnetic rotor will stop running. under these circumstances. The engine must be shut down and restarted to resume synchronous operation. For cage asynchronous motors. There is no such problem (although for centrifugal pumps, if the measurement is correct, this problem will not occur during operation). Because its running and starting can be performed asynchronously. By installing a spacer sleeve in the gap between the outer magnetic rotor and the inner magnetic rotor (for complete consideration, sometimes two layers may be required). The water pump can be completely sealed. The application of a centrifugal pump driven by an electromagnetic coupler is similar to that of a canned motor pump.
The above is the working principle of the magnetic pump, and the magnetic coupler should not be confused with the electromagnetic coupler. Electromagnetic couplers are used to switch or provide protection against shock loads. Magnetic drive pump manufacturers and suppliers from China

We know that the structure of the Air operated double diaphragm pump air chamber is generally used to separate the water chamber from the air chamber. After the air chamber is filled with compressed air, the pulsation of the water in the water chamber is absorbed by the compressed air in the air chamber through the rubber diaphragm Up. The function of the air chamber is to use the compressibility of air, or called elasticity, to absorb the water pulsation of the AODD pump and stabilize it. The water flow into the system is basically stable. However, to achieve the requirement of a basically stable water flow, the air pressure in the air chamber must be compatible with the water pressure. Inflation method of diaphragm pump air chamber: Before the diaphragm pump is operated, inflate the air chamber first, and the air pressure is greater than the working pressure of the pump. Drive the AODD pump and adjust to the working pressure. At this time, you can see the pump’s water outlet hose shakes violently. Take a needle and put it on the air nozzle to deflate. As the deflation progresses, the shaking of the water outlet hose will gradually disappear.
