Lo correcto hubiera sido decir: ''Habiendo llegado la tecnología a una alta calidad de fabricación... aún existen fabricantes antediluvianos que la ignoran''
Somehow the pumps seems to be performing at acceptable level, dispite the workmanship; probably not for continuous duty and low speed. Not seen any shaft and impeller balancing.
It is difficult to imagine a less suitable location in which to build pumps, nor a less suitable method of installing and caring for bearings! Why on earth would one choose to build anything on a bed of sand! Particularly something which uses unsealed ball bearings! Pride of workmanship, quality and product longevity are certainly absent...
The delicacy of the assembly process, the ingenius alternative use of tools, the near semiconductor grade clean room conditions, as a 50 year toolmaker, I am impressed!
What amazes me is that these guys assemble bearings, etc., and handle tools contaminated with soil- When I work on my car’s bearings or other components, I do it on a clean paved surface and keep all my tools from soil contamination.
На 3:50 работяга забивает вал кувалдой, а на конце вала - резьба :( На 4:16 это и вся смазка для подшипника? :( На 3:37 токарь посадку рабочего колеса делает из-под сверла :(
Добавлю, рабочее колесо не балансировано. Плюс бьёт со страшной силой и посадочные места под подшипники провалены ( это там где он ключом из осаживал). Колхоз, вибрация и проварот подшипников обеспечены!
Гонят количество. Есть токарный станок отсюда можно всё это поправить. Сделать оснастку. Но всё замедлится. Посадка под вал после сверла. Центровка? Да на х она нужна...
They are just knocking those bearings and shafts with iron hammers that will surely deform them. They must have used brass hammers and put an utmost care on installing the shafts and bearings.
Lots of people commenting on how they "press" in the bearings, but looking at the heap fo sand they work in and a lot of which will inevitably end up in the bearing as well, I am not sure if that really matters. My question is: do they really not know better or do the just not give a flying...?
It's appalling how cavalier they are with safety including the lack of any eye protection. This is not about not being able to afford one but cultural backwardness of not valuing safety.
@@danielzunigagutierrez6300 These countries are in so much debt to Western countries they can’t even think of safety or better life, except how to return the high interest debt that’s normally average equal to their GDP. The more they fall behind the more of their future resources they loose to Western wealthy countries. This country in video has $10,000 debt on every child born there. Or Every child has a burden of $10,000 of debt to payback, which could go up if borrowing continues.
The degenerated influence of Islam where safety or even life isn't valued because an accident is just Gods will. Even when a tower crane collapsed on Mecca and killed many people they couldn't care less about the fact that their own negligence caused it.
Inserting those bearings that way is very WRONG. It will destroy the bearing cages. They should first learn how to do this the right way, it is basic knowledge for any mechanic.
Не смазки в подшипники не оправки загнать их, а про соосность я вообще молчу там нужно один самонастроивающийся ставить не балансировки крыльчатка БАСУРМАНЕ ОДНИМ СЛОВОМ.
You noticed the dirt. That's GuD observation. But you didn't notice 2 things. 1- use of used bearings 2- hammering while fitting at the inner ring of bearing, which makes it more weaker and risky.
@@williamlee7371 your right you don’t hit then, the pump bore should be machined too have a .0005 bearing slip fit and when you install the end cover it will keep the bearings in place along with the weight of the rotating element ( impeller and shaft) your should ever press bearings on because it damages the bearings. I either use a induction heater to install a bearing over a shaft ( never over 350 degrees) or put the bearing in dry ice to shrink the bearing to install in a bore. I worked a Nuclear Power Plant all over the United States and worked on hundreds on pump including nuclear reactor cooling pumps and pump that pumped 250,000 gallon per minute from the ocean ( yes 250,000 GPM ) have a good day
They could have a real factory with just a little more effort. Concrete floor, work benches, bearing press, impeller balance stand, safety glasses and some bearing grease. Then they would produce a quality cheap product without maiming the employees.
You are right grumpy bill. They have realised that you don't need to spend hundreds of billions of dollars to explode rockets on launch pads or collect dirt when we have enough on planet earth.
Someone should teach them how to install bearings so they don't destroy them before they're even used. Also assembling them in sand and dust isn't conducive to longevity.
Oh you need this flange lathed flat? Sure, I'll eyeball it. Heavy cast metal part? No problem, just throw it on the ground. Need a bearing installed? Well I'll just beat it in with a big hammer. Gotta hand it to them though. They get shit done. "Do you guys offer a warranty?"
