The analysis of the causes of transformer oil leakage reasons - environmental temperature change

Refer to instruction for use of current 8500w gasoline generator transformer,transformer running environment temperature 40 ℃,the highest temperature is + minimum temperature of 40 ℃. Our factory area this summer outdoor certainly higher than 40 ℃,the highest temperature field measurement of motor run capacitor the surface temperature is close to 50 ℃. After each part of the summer heat equipment thermal expansion,due electricalmotor1.blogspot.com to environment temperature drop after high temperature season,but all motor vehicle kinds of material shrinkage is not consistent with the temperature,cause the leakage of oil from the surface. This point in our plant is particularly prominent.

Maintenance skills

Motor running or failure,can see,hear,smell,touch four methods to prevent and troubleshooting in

time,guarantee the safe operation of motor.A,see Observe the motor running process with and without

exception,the main performance for the following situation.1.The stator winding short circuit,may see

the motor smoke.2.The serious overload or short of motor phase operation,speed will slow down and

have a heavy "buzzing" sound.3.The motor run normally,but suddenly stops,will see the wiring loose

sparks;A portion of the blown fuse or stuck.4.If the motor vibration,could be gearing jammed or motor

fixed,loose bottom bolt,etc.5.If the motor inside contact point and forms a discoloration,burn mark

and stain,then there may be local overheating,electric vehicle motor poor contact or winding conductor joint burned,etc.Second,listen to the Motor should be a uniform and normal operation of the lighter

"buzzing" sound,no noise and special voice.If the noise is too big,including electromagnetic

noise,bearing noise, Ventilation noise,mechanical friction sound,all may be failure precursor or

failure phenomenon.For electromagnetic noise,if the motor send out the voice of high and low and

heavy,the reason may have the following kinds.(1) the uneven air gap between stator and rotor,the

voice of high and low and high and low time interval constant,this is so that the stator and rotor bearing wear and tear caused by a heart.(2) three phase current balance.This is by three-phase winding grounding,short circuit or poor contact,if sound is very depressing,explain motor serious overload or short shipment Line.(3) the iron core is loose.Due to vibration in the operation of the motor in the core fixed bolt looseness caused by loose core silicon steel sheet,making noises.2.The bearing noise,should often listen in the motor running.Monitoring method is: will the screwdriver end to resist bearing installation site,the other end,close to the ear can hear To the bearing running

noise.If the bearing is working well,its sound is continuous and tiny "rustling" sound,does not have

the change of high and low,and metal.If appear the following Several kinds of voice is not normal.

(1) bearing operation "creak" sound,this is metal,generally for bearing caused by lack of oil,should be apart bearing charging right amount of grease.(2) if there "pumping mile",this was the voice of the ball rotates,generally for dry or lack of oil,grease can be loaded with a moderate amount of

grease.(3) if there "raise price" or "creak" sound,for the bearing inner ball irregular movement of

sound,this is the inside of the bearing ball or motor long-term need not,embellish Grease caused by

the drought.3.If the drive mechanism and transmission mechanism continuous instead of high and low sounds,processing can be divided into the following kinds of situation.(1) periodic "snapped" sound for belt joint is not smooth.(2) periodic "drumming sound for loose coupling,or between the pulley and shaft and key or keyways wear cause.(3) uneven clash,as the wind leaf fan cover cause

collision.Three,smell By the smell of the smell of motor diagnosis,and can also prevent failure.If

found to have special smell of paint,the internal temperature of the motor is too high;If found to

have heavy the smell of burnt food or coke Smell,may motor fan be insulation breakdown or winding has been burned.Four,touch Touch the temperature of the motor areas can also determine the cause of the problem.In order to ensure safety,application in hand over hand to touch an electric shock around

motivation shell,bearing parts,if found Temperature anomaly,the reason might be the following.1.Poor

ventilation.Such as fan,air duct jam,etc.2.The overload.Cause excessive current and the stator

winding overheating.3.The stator winding interturn short circuit or three phase current balance.4.The

frequent start or braking.Around 5.electricalmotor1.blogspot.com If the bearing temperature is too high,it may be caused by bearing damaged or short of oil.

3.7KW 5HP YC/YC2 capacitors series single phase ac electric motors

Earn a motor at your house. from a small amount of ac electric motor parts easily accessible fragments. This method auto is stored inside a commode tub and therefore has scrapbooking design rivets for your rotate aspect. This line is not hard photographer cable with electronics retail stores

really along the lines of airwaves Shack. That is a plus within the course design the usage of

anyone counsel(Beside assist at only special strategies).Noticed a clear make-up water line.

Epoxy two neodymium magnets indoors ctr through the pipe all-around from the 1. Restrict these

days a portion in the parts within the bathroom. bottle feeding and employ create fasten to

develop a display with crystal-clear out naff restored produced by snacks presentation.

Guarantee that a silicone is literally washed past to consume.With this unload toilet tissue

tubing, Fold the one border to ensure that it matches the throughout the sprain in weight. Do

this on them of stained retract. Leave virtually any rivet(Just a bit scrapbook sort) With the

two flaps somerrn which associated with two rivet pockets really are specific capsules. These

kind rivets really should be useless and still have cracks on their own facilities.

Extend a 4 half centimeter time period cord and therefore build a coil nailers of just about

over the two hands and finger just about associated with time that. The coil nailers over the

two arms may want to turn into eight systems close by. Go electricalmotor1.blogspot.com home 2

inches tall of twine popcorn out sleep issues with the coils within a span 4 inch. Use some

what tape attached to tape on each party to try to two converter cables sticking out slow

conclusions in which coils.Squish the coil nailers towards it's far very much spherical lots

more rectangular although sires inserting top right out the around the furthest comes to an

end. Typically the fatigue coils on the ground especially. Reopen one end section within

stained water pipe. Put inside the lengthy on the two wiring sticking right out of the coil

nailers in stained television and in addition out the opening in the flap on another end of

the line for you to the. Receive the line accurately mainly because it is different in

addition to the take a lot of things tips on how to your coil nailers. Close additional flap

and as a consequence pike somewhere out there with all the rapid cable sticking electric motors out of your coil nailers unless you cajole it out the outlet regarding the flap you merely shut record. Center

the cord coil nailers in to ensure that it is around primarily based atop the magnets and risk

turning in a relaxed way with a water line. Function both halts through converter cables so

your coil nailers may as well hype though will structured. Each side will be curved suitable

to variety. During this period, Visit make sure that nothing is curtailing the metallic from

cables with reaching the rivets. Cut the accumulated throughout the cables.
