V nekem smislu učinek delovanja ležajev neposredno določa življenjsko dobo in kakovost elektromotorjev.
Mast za ležaje je bistveno mazivo za zagotavljanje nemotenega delovanja ležaja.
Če pa je količina masti premajhna ali prevelika, lahko poškoduje ležaj. Nezadostna količina odvečne masti lahko povzroči obrabo in poškodbe ležajev elektromotorja, preveč masti pa lahko povzroči pregrevanje in tresljaje med delovanjem indukcijskega motorja.
Poleg kakovosti samih ležajev je mazanje zelo kritičen element pri določanju učinkovitosti delovanja ob okvari ležaja, vključno s celotnim življenjskim ciklom industrijskega motorja od proizvodnje, skladiščenja in uporabe, mazanje je kritična kontrolna točka.
Zato je pomembno, da uporabite ustrezno količino masti za ležaje ter redno pregledujete in vzdržujete pokrov ležaja, da zagotovite, da je pravilno namazan.
To bo pomagalo preprečiti prezgodnjo obrabo in poškodbe AC motorja ter podaljšalo njegovo celotno življenjsko dobo.
Za ležajno mast je poleg delovanja mazalnih nastavkov in uporabnosti delovnih pogojev indukcijskega motorja ter razmerja z ležajnimi deli zelo pomemben dejavnik nadzor nad količino masti med delovanjem ležaja, količina masti, če lahko zagotovi normalno delovanje ležaja, lahko, če je prenapolnjena, vključno z odvajanjem maščobe, ni gladka, povzroči kopičenje preveč maščobe v ležaju.
Tako da bo med delovanjem elektromotorja zaradi trenja in toplote, kar povzroči izgubo zaradi razgradnje maščobe, nato pa ležaje motorja v nenamazanem stanju delovanja, v zelo kratkem času se zdi, da ležaj razpade in drži gred resne posledice.
Redno vzdrževanje in pregled ležajnih ščitov mora vključevati spremljanje količine ležajne masti in zagotavljanje, da je ni premalo ali preveč.
To bo pomagalo preprečiti prezgodnjo obrabo in poškodbe motorja, pa tudi pregrevanje in tresljaje med delovanjem.
Pravilno mazanje je ključnega pomena za učinkovitost in dolgo življenjsko dobo ležajev in ga je treba skrbno nadzorovati skozi celoten življenjski cikel elektromotorja.
Dokazano je, da je ležajni sistem ključni krmilni element motornega izdelka, kako določiti razmerje med deli, kakšno mast izbrati, kako zagotoviti neškodljivo kroženje masti med delovanjem ležaja, kako zagotoviti metabolizem masti med delovanjem ležaja so ključne točke, ki jih ni mogoče prezreti.
Če povzamemo, pravilno mazanje ležajev je ključnega pomena za nemoteno delovanje in dolgo življenjsko dobo motorja.
Tako nezadostna kot prekomerna količina masti za ležaje lahko povzroči poškodbe ležaja in vpliva na splošno delovanje asinhronskega motorja.
Izvajati je treba redno vzdrževanje in pregledovanje ležajev, da bi spremljali količino ležajne masti in zagotovili, da je ni premalo ali preveč. S tem je mogoče preprečiti prezgodnjo obrabo in poškodbe AC motorja ter podaljšati celotno življenjsko dobo industrijskega motorja.

pogoste okvare pri delovanju ventilatorja
Delovni medij ventilatorjev v cementni industriji pogosto vsebuje določeno količino homogenih delcev različnih velikosti in oblik, kot je sistem za odstranjevanje prahu ventilatorja z induciranim vlekom, pnevmatsko transportno puhalo.
Ker ti ventilatorji delujejo v prašnem zračnem toku, prašni delci v zračnem toku povzročajo obrabo ventilatorja, pa tudi v lopaticah ventilatorja, ki so pritrjene, da kopičijo pepel, ta obraba in pepel pa sta neenakomerna.
Thus, the fan rotor balance is damaged, causing fan vibration, shorten the fan life, serious can make the fan can not work properly.
Especially the fan blade wear is the most serious, it not only destroys the flow characteristics of the fan, and easy to cause blade fracture and flying car and other major accidents.
Transmission parts wear is also a common problem of fans, including a variety of shafts, rollers, reducers, most motors, pumps and other bearing bits, bearing seats, keyways and threads and other parts, the traditional welding machine processing method is easy to cause material damage, resulting in component deformation or fracture, with greater limitations; brush plating and spraying and then machining methods often need to be outsourced, not only long repair cycle, high cost, and because the repair.
The material is still metal material, can not fundamentally solve the cause of wear and tear (metal impact resistance and poor yield).
More many parts can only be scrapped and replaced, greatly increasing the production costs and inventory of spare parts, so that the enterprise good resource advantage was idle and wasted.
Solutions to common failures in the operation of the fan
To solve the common problem of wear and tear on transmission parts, a new method called laser cladding technology has been developed.
This technology uses a high-energy laser beam to melt the surface of the worn part and apply a layer of wear-resistant material to the surface.
The material is then fused with the base metal to form a strong bond, effectively repairing the worn part without causing deformation or material damage.
This method has the advantages of high repair efficiency, low repair cost, and improved component performance and durability.
To prevent the accumulation of dust and ash on the blades of fans working in dusty environments, the use of a protective coating on the blade surface has been proven to be effective.
This coating can reduce the adhesion of dust particles to the blade surface and reduce wear and tear caused by dust accumulation.
In addition, the use of ceramic bearings and seals can also effectively reduce wear and tear in dusty environments.
By adopting these solutions, the service life of fans can be greatly extended and the overall performance and efficiency of the three phase motor can be improved.
2 vibration failure of electric motors
The fan and the electric motor are linked by a coupling to transfer motion and torque.
Misalignment is the most common fault of the fan, and 60% of fan failures are related to misalignment.
The misalignment fault of the fan is the degree of tilt or offset between the axis line and the bearing centerline of the two rotors of the fan and the motor.
The misalignment of the fan rotor can be divided into coupling misalignment and bearing misalignment.
After the fan rotor system produces misalignment fault, it will produce a series of dynamic effects unfavorable to the operation of the equipment during the rotation process, causing the deflection of the coupling, the wear of the bearing, the oil film steady state and the deflection of the shaft, etc.
It not only makes the mutual position of the journal and bearing installation of the rotor and the working state of the bearing change, but also reduces the inherent frequency of the shaft system at the same time, so that the additional force on the rotor and the bearing leads to the fan .
The abnormal vibration and early damage of the double shielded bearings , the harm is great.
For fan misalignment failure, you can use the laser alignment instrument to solve, convenient and fast.
laser alignment technology
Laser alignment technology is a new method of alignment that uses a laser to measure the relative position and alignment of the fan and grease lubricated motors.
This method has the advantages of high accuracy, high efficiency, and easy operation, and can effectively solve the problem of fan misalignment.
By using laser alignment technology, the service life of the fan can be extended and the overall performance and efficiency of the electric motor can be improved.
In addition, regular maintenance and inspection of fans is also critical to preventing common failures such as transmission parts wear and dust accumulation on fan blades.
By adopting these solutions and ensuring proper lubrication of bearings, the service life of motors can be greatly extended and the overall performance and efficiency of the Squirrel cage motor can be improved.
