自吸磁力泵-磁力泵-KAYSEN泵業(yè)

GERMANY KAYSEN PUMP CO .,LTD

自吸磁力泵是一種通過磁力傳動器來實現(xiàn)無接觸力矩傳遞從而以靜密封取代動密封，使泵達(dá)到完全無泄漏的目的。它由自吸泵、磁力傳動器、電動機三部分組成，關(guān)鍵部件磁力傳動器由外磁轉(zhuǎn)子、內(nèi)磁轉(zhuǎn)子及不導(dǎo)磁的隔離套組成。具有內(nèi)封閉好、降能耗等多方面特點，使用時要注意防止顆粒進(jìn)入、干摩擦等事項和問題。

主要特點：

●永磁體 由稀土永磁材料制成的永磁體工作溫度范圍廣(-45－400℃)，矯頑力高，磁場方向具有很好的各向異性，在同極相接近時也不會發(fā)生退磁現(xiàn)象，是一種很好的磁場源。
●隔離套 在采用金屬隔離套時，隔離套處于一個正弦交變的磁場中，在垂直于磁力線方向的截面上感應(yīng)出渦電流并轉(zhuǎn)化成熱量。
●冷卻潤滑液流量的控制 泵運轉(zhuǎn)時，必須用少量的液體對內(nèi)磁轉(zhuǎn)子與隔離套之間的環(huán)隙區(qū)域和滑動軸承的摩擦副進(jìn)行沖洗冷卻。冷卻液的流量通常為泵設(shè)計流量的2%-3%，內(nèi)磁轉(zhuǎn)子與隔離套之間的環(huán)隙區(qū)域由于渦流而產(chǎn)生高熱量。當(dāng)冷卻潤滑液不夠或沖洗孔不暢、堵塞時，將導(dǎo)致介質(zhì)溫度高于永磁體的工作溫度，使內(nèi)磁轉(zhuǎn)子逐步失去磁性，使磁力傳動器失效。當(dāng)介質(zhì)為水或水基液時，可使環(huán)隙區(qū)域的溫升維持在3-5℃；當(dāng)介質(zhì)為烴或油時，可使環(huán)隙區(qū)域的溫升維持在5-8℃。
●滑動軸承 磁力泵滑動軸承的材料有浸漬石墨、填充聚四氟乙烯、工程陶瓷等。由于工程陶瓷具有很好的耐熱、耐腐蝕、耐摩擦性能，所以磁力泵的滑動軸承多采用工程陶瓷制作。由于工程陶瓷很脆且膨脹系數(shù)小，所以軸承間隙不得過小，以免發(fā)生抱軸事故。 由于磁力泵的滑動軸承以所輸送的介質(zhì)進(jìn)行潤滑，所以應(yīng)根據(jù)不同的介質(zhì)及使用工況，選用不同的材質(zhì)制作軸承。
●保護(hù)措施 當(dāng)磁力傳動器的從動部件在過載情況下運行或轉(zhuǎn)子卡死時，磁力傳動器的主、從動部件會自動滑脫，保護(hù)機泵。此時磁力傳動器上的永磁體在主動轉(zhuǎn)子交變磁場的作用下，將產(chǎn)生渦損、磁損，造成永磁體溫度升高，磁力傳動器滑脫失效。
 

主要優(yōu)點：
由于泵軸、內(nèi)磁轉(zhuǎn)子被泵體、隔離套完全封閉，從而徹底解決了“跑、冒、滴、漏”問題，消除了煉油化工行業(yè)易燃、易爆、有毒、有害介質(zhì)通過泵密封泄漏的安全隱患，有力地保證了職工的身心健康和安全生產(chǎn)。
●無需安裝底閥和灌引水。
●泵軸由動密封變成封閉式靜密封，徹底避免了介質(zhì)泄漏。
●無需獨立潤滑和冷卻水，降低了能耗。
●由聯(lián)軸器傳動變成同步拖動，不存在接觸和摩擦。功耗小、效率高，且具有阻尼減振作用，減少了電動機振動對泵的影響和泵發(fā)生氣蝕振動時對電動機的影響。
●過載時，內(nèi)、外磁轉(zhuǎn)子相對滑脫，對電機、泵有保護(hù)作用。
●當(dāng)磁力傳動器的從動部件在過載情況下運行或轉(zhuǎn)子卡死時，磁力傳動器的主、從動部件會自動滑脫，保護(hù)機泵。此時磁力傳動器上的永磁體在主動轉(zhuǎn)子交變磁場的作用下，將產(chǎn)生渦損、磁損，造成永磁體溫度升高，磁力傳動器滑脫失效。
●強自吸、結(jié)構(gòu)緊湊，外形美觀，體積小，噪音低，運行可靠，使用維修方便
 

主要應(yīng)用：

自吸式磁力驅(qū)動泵適用于工業(yè)和城市給排水，環(huán)保、建筑、化工、制藥、染料、印染、釀造、電力、電鍍、造紙、工礦沖洗，設(shè)備冷卻等。

自吸磁力泵故障原因及解決方法：
 

Fluorine-lined magnetic pump

Self-priming magnetic pump

Fluoroplastic magnetic pump

Magnetic vortex pump

Magnetic gear pump

Stainless steel magnetic pump

The self-priming magnetic pump is a non-contact torque transmission through a magnetic actuator to replace the dynamic seal with a static seal, so that the pump can be completely leak-free. The utility model is composed of a self-priming pump, a magnetic actuator and a motor. The key component magnetic actuator is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic magnetic isolation sleeve. It has many characteristics such as good internal sealing and energy reduction. When using, care should be taken to prevent particles from entering and dry friction.

main feature:

● Permanent magnets made of rare earth permanent magnet materials have a wide operating temperature range (-45-400 ° C), high coercive force, good anisotropy in the direction of the magnetic field, and will not occur when the same pole is close. Demagnetization is a good source of magnetic field.

● Isolation sleeve When the metal isolation sleeve is used, the isolation sleeve is in a sinusoidal alternating magnetic field, and an eddy current is induced and converted into heat in a section perpendicular to the direction of the magnetic line.

● Control of the flow rate of the cooling lubricant When the pump is running, the air gap between the inner magnetic rotor and the spacer sleeve and the friction pair of the sliding bearing must be flushed and cooled with a small amount of liquid. The flow rate of the coolant is usually 2% to 3% of the pump design flow rate, and the annulus region between the inner magnetic rotor and the isolation sleeve generates high heat due to the eddy current. When the cooling lubricating fluid is not enough or the flushing hole is not smooth or blocked, the medium temperature is higher than the working temperature of the permanent magnet, so that the inner magnetic rotor gradually loses magnetism and the magnetic actuator fails. When the medium is water or water-based liquid, the temperature rise of the annulus region can be maintained at 3-5 ° C; when the medium is hydrocarbon or oil, the temperature rise of the annulus region can be maintained at 5-8 ° C.

●Sliding bearing The material of the magnetic pump sliding bearing is impregnated graphite, filled with polytetrafluoroethylene, engineering ceramics, etc. Because engineering ceramics have good heat resistance, corrosion resistance and friction resistance, the sliding bearings of magnetic pumps are mostly made of engineering ceramics. Since the engineering ceramics are very brittle and the expansion coefficient is small, the bearing clearance must not be too small to avoid the occurrence of a shaft hazard. Since the sliding bearing of the magnetic pump is lubricated by the medium to be conveyed, the bearing should be made of different materials according to different media and working conditions.

●Protection measures When the driven part of the magnetic actuator runs under overload or the rotor is stuck, the main and driven parts of the magnetic actuator will automatically slip off and protect the pump. At this time, the permanent magnet on the magnetic actuator will generate eddy loss and magnetic loss under the action of the alternating magnetic field of the active rotor, causing the temperature of the permanent magnet to rise and the magnetic actuator to slip off.

The main advantage:

Since 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 from the pump seal leakage. The safety hazard has effectively guaranteed the physical and mental health and safe production of employees.

● No need to install bottom valve and irrigation water.

●The pump shaft is changed into a closed static seal by the dynamic seal, which completely avoids the leakage of the medium.

● No need for independent lubrication and cooling water, reducing energy consumption.

● 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.

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

● When the driven part of the magnetic actuator runs under overload or the rotor is stuck, the main and driven parts of the magnetic actuator will automatically slip off and protect the pump. At this time, the permanent magnet on the magnetic actuator will generate eddy loss and magnetic loss under the action of the alternating magnetic field of the active rotor, causing the temperature of the permanent magnet to rise and the magnetic actuator to slip off.

● Strong self-priming, compact structure, beautiful appearance, small size, low noise, reliable operation, easy to use and maintain

main application:

The self-priming magnetic drive pump is suitable for industrial and urban water supply and drainage, environmental protection, construction, chemical, pharmaceutical, dye, printing and dyeing, brewing, electric power, electroplating, papermaking, industrial and mining washing, equipment cooling and so on.
