進(jìn)口不銹鋼磁力泵(進(jìn)口磁力泵）

德國KAYSEN凱森進(jìn)口不銹鋼磁力泵概述

進(jìn)口不銹鋼磁力泵是由磁力泵由泵、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。 當(dāng)電動機帶動外磁轉(zhuǎn)子旋轉(zhuǎn)時，磁場能穿透空氣隙和非磁性物質(zhì)，帶動與葉輪相連的內(nèi)磁轉(zhuǎn)子作同步旋轉(zhuǎn)，實現(xiàn)動力的無接觸傳遞，將動密封轉(zhuǎn)化為靜密封。由于泵軸、內(nèi)磁轉(zhuǎn)子被泵體、隔離套完全封閉，從而 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)。

將n對磁體(n為偶數(shù))按規(guī)律排列組裝在磁力傳動器的內(nèi)、外磁轉(zhuǎn)子上，使磁體部分相互組成完整藕合的磁力系統(tǒng)。當(dāng)內(nèi)、外兩磁極處于異極相對，即兩個磁極間的位移角Φ=0，此時磁系統(tǒng)的磁能*；當(dāng)磁極轉(zhuǎn)動到同極相對，即兩個磁極間的位移角Φ=2π/n，此時磁系統(tǒng)的磁能*。去掉外力后，由于磁系統(tǒng)的磁極相互排斥，磁力將使磁體恢復(fù)到磁能*的狀態(tài)。于是磁體產(chǎn)生運動，帶動磁轉(zhuǎn)子旋轉(zhuǎn)。

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。渦流的表達(dá)式為：其中Pe－渦流；K—常數(shù)；n—泵的額定轉(zhuǎn)速；T－磁傳動力矩；F－隔套內(nèi)的壓力；D－隔套內(nèi)徑； 一材料的電阻率； —材料的抗拉強度。當(dāng)泵設(shè)計好后，n、T是工況給定的，要降低渦流只能從F、D等方面考慮。選用高電阻率、高強度的非金屬材料制作隔離套，在降低渦流方面效果十分明顯。

冷卻潤滑液流量

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。

Germany Kaysen imported stainless steel magnetic pump overview

The stainless steel magnetic pump is composed of a magnetic pump consisting 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 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 the inner magnetic rotor connected with the impeller rotates synchronously to realize the non-contact transmission of the power, and the dynamic seal is converted into a static seal. 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.

The n pairs of magnets (n is an even number) are regularly arranged and assembled on the inner and outer magnetic rotors of the magnetic actuator, so that the magnet portions form a complete coupled magnetic system. When the inner and outer magnetic poles are in opposite poles, that is, the displacement angle Φ=0 between the two magnetic poles, the magnetic energy of the magnetic system is the lowest; when the magnetic pole rotates to the same pole, the displacement angle between the two magnetic poles is Φ=2π. /n, at this time the magnetic energy of the magnetic system is the largest. After the external force is removed, the magnetic force will return the magnet to the state with the lowest magnetic energy because the magnetic poles of the magnetic system repel each other. The magnet then moves to drive the magnetic rotor to rotate.

main feature:

Permanent magnets

The permanent magnet made of rare earth permanent magnet material has a wide operating temperature range (-45-400 ° C), high coercive force, good anisotropy in the direction of the magnetic field, and no demagnetization when the same pole phase is close. It is a good source of magnetic field.

Isolation set

When a metal isolating sleeve is used, the spacer 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. The expression of the eddy current is: where Pe- eddy current; K-constant; n - rated speed of the pump; T-magnetic drive torque; pressure in the F-sleeve; D- spacer inner diameter; resistivity of a material; Tensile strength. When the pump is designed, n and T are given by the working conditions. To reduce the eddy current, only F, D and so on can be considered. The use of high-resistivity, high-strength non-metallic materials to make the isolation sleeve, the effect is very obvious in reducing the eddy current.

Cooling lubricant flow

When the pump is running, a small amount of liquid must be used to flush and cool the annulus region between the inner magnetic rotor and the spacer sleeve and the friction pair of the sliding bearing. 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, and the like. 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.
