The characteristics, uses and working conditions of the magnetic pump

The magnetic pump consists of a pump, a magnetic actuator and a motor. The key component magnetic actuator consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and the non-magnetic material, and drive the inner magnetic rotor connected with the impeller to rotate synchronously to realize the non-contact transmission of the power, and convert the dynamic seal into a static seal. Because the pump shaft and the inner magnetic rotor are completely closed by the pump body and the isolation sleeve, the problem of “running, escaping, dripping and leaking” is completely solved, and the flammable, explosive, toxic and harmful medium of the refining and chemical industry is eliminated. The safety hazards have effectively guaranteed the physical and mental health and safe production of employees.

Magnetic pump features:

The mechanical seal of the pump has been eliminated, which completely eliminates the inevitable run, run, drip and leak of mechanical seal centrifugal pumps, and is the best choice for leak-free factories.

Since the overcurrent components of the pump are made of stainless steel and engineering plastics, corrosion resistance is achieved.

The pump's magnetic coupling and pump body are integrated into one, so the structure is compact, easy to maintain, safe and energy-saving.

The magnetic coupling of the pump acts as an overload protection for the drive motor.

Magnetic pump working conditions:

The magnetic pump transport medium has a density of not more than 1300 kg/m3 and a viscosity of not more than 30 吆-6 m3/s of ferromagnetic and fiber-free liquid. The rated temperature of the conventional magnetic pump is metal or f46 lining for the pump body, the maximum working temperature is 80 ° C, the rated pressure is 1.6mpa; the temperature of the high temperature magnetic pump is ≤ 350 ° C; for the pump body is non-metallic material, the maximum temperature is not Above 60 ° C, the rated pressure is 0.6mpa.

For liquids with a transport medium density greater than 1600 kg/m3, the magnetic coupling needs to be designed separately.

The bearing of the magnetic pump is lubricated and cooled by the medium to be transported, and the drum magnetic pump is strictly prohibited from running at no load.

The purpose of the magnetic pump:

The magnetic pump is characterized by its full sealing, no leakage and corrosion resistance. It is widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television printing, national defense and other departments to pump flammable, explosive and toxic. With precious liquids, it is the ideal pump for creating a leak-free, pollution-free civilized workshop and a civilized factory.

Advantages of magnetic pumps

Compared with centrifugal pumps that use mechanical seals or packing seals, magnetic pumps have the following advantages:

1. The pump shaft is sealed by a dynamic seal into a closed static seal, completely avoiding media leakage.

2. Eliminates the need for separate lubrication and cooling water, reducing energy consumption.

3. From the coupling drive to synchronous drag, there is no contact and friction. Low power consumption, high efficiency, and damping damping effect, reducing the impact of motor vibration on the pump and the impact of the cavitation vibration of the pump on the motor.

4. When overloaded, the inner and outer magnetic rotors are relatively slippery, which has a protective effect on the motor, valve and pump.

KSNFJ is a factory ready-mix powder that has undergone strict quality control to facilitate on-site construction. It contains a selection of metallic mineral aggregate materials and specialty Portland cement, as well as special additives to promote construction performance. Specially made materials ensure gradation and free from impurities, which aggregate shows good conductivity and wear resistance.

KSNFJ for the need to improve the wear resistance, resistance of the concrete surface, in particular, sparks, antistatic areas. For example: flammable warehouse, chemical plants, petrochemical plants, dangerous products workshop, gas stations, liquefied gas stations, hangars, textiles, electronics, paper, printing and other long-term electrostatic regions.

Product Advantages:

1. To make the ground extremely hard, wear and impact resistance

2. With the concrete surface to form a monolithic bond

3. Fireworks conductive static

4. Anti-all kinds of oil, grease erosion

5. Easy to construct

Material properties:

Wear resistance: The KSNFJ-treated concrete floor exhibits at least three times more wear resistance than the untreated concrete floor.

Electrical properties: KSNFJ shows good electrical conductivity to dissipate static electricity. KSNFJ can be grounded in the traditional way with specific requirements. Due to the ductility of metallic materials in the ground so that the impact of metal collision with a high degree of fireworks.

Surface resistance: 1.0×105 ~1.0×108Ω

Compressive strength: Using the same amount of water as the actual construction, KSNFJ test block 28 days standard compressive strength of 90Mpa.

Storage: KSNFJ and intact packaging stored at room temperature and dry environment, the storage period of six months.

Health and Safety: The cement powder contained in KSNFJ will adversely affect the skin during normal use. When the product is mixed with dampness, the released alkali will damage the skin, irritate the eyes and respiratory system, avoid inhalation of its powder, and avoid skin and eye contact. Wear suitable gloves and eye protection. Once touched the skin, wash with water. Once you reach your eyes, immediately wash with plenty of water and seek medical treatment.
