Densely small cracks appeared on the dust ring, and the high-strength hose clamp below should normally be made of stainless steel. At this time, it was rusty and, most importantly, broken. Ji Dongqing frowned.

"First, the quality of the hose clamp is unqualified! Second, the quality of this seal is seriously unqualified! If I guessed correctly, this material is chloroprene plus butadiene rubber with a vulcanizing agent, antioxidants and anti-aging

agent, and a certain proportion of natural rubber! This wind power tower is so short, it should use a dustproof seal whose main body is EPDM rubber, not something made of this material!"

"Seawater infiltration is not terrible. The large amount of high-temperature resistant grease in the inner ring of the bearing can withstand it for a while. What is most scary is the hose clamp we just saw. Once the fragments of this thing enter the inside of the bearing, the bearing will wear. At such a high temperature

Replacing the bearing at the position is not particularly difficult, because the part where the outer ring of the bearing matches the bearing hole has an interference fit. Do you want to remove it? It’s like reaching the sky!”

"In addition, the fit between your main shaft and the inner ring of the bearing is also an interference fit. The shaft was frozen with nitrogen and then installed. If there is a fault, just wait and replace the reducer!"

Facing Wang Xiaodan, Ji Dongqing had no reservations. Ju Xiaojie's eyes changed several times and he looked at Wang Xiaodan.

"Mr. Ji, is it feasible if we cut off the dust seal and reinstall it by docking it? Of course, this is on the premise that there is no damage to the wind turbine bearings. This project is very important to us!"

As Ju Xiaojie said that, he moved the screen closer to Ji Dongqing. Ji Dongqing secretly thought that the other party was indeed an expert. This method of installing the dust seal was standard in Yang Jian's German manual.

If the other party has not carefully watched the above content, it is impossible to know. Facing the expert Ji Dongqing, he did not dare to show any slightness. He bent forward and carefully watched every frame above.

"Talk back to me!"

"...Okay, follow Commander Ji's command below!"

"receive!"

Soon news came from the top of the tower, and Ji Dongqing carefully stared at every point above.

"Use a knife to cut the dust seal, and then throw the hose clamp into the sea. Do not touch the bearing. I hope your engineers will add a dust cover when designing the bearing. In that case, everything we do will make sense. It is best that

Metal dust cover.”

Ji Dongqing directed the workers above to start the operation. The other person took a special tool to hook the dust seal, and then started cutting with an electric tool. Soon a large piece of rubber fell into the sea, and the workers on the ship hid in the cabin one after another.

"Fortunately, there is a metal dust seal. Mr. Ju, take off all the black rubber dust seals. Pull out the hose clamp without leaving any on it, and then take it down! The material of this thing is wrong. It is not stainless steel, but

That kind of stainless steel! It can barely be used on land, but it's a recipe for death if used in a salt spray environment at sea! In addition, do you want to replace the dust seal tape? Is it still a product produced by the original manufacturer? If so,

Just don’t waste your time and keep applying!”

Ji Dongqing breathed a long sigh of relief. Fortunately, the damaged part of this fan was not very large. Now it seems that the noise and unstable operation are due to the excessive gap in a certain part! This part of the problem has been solved. It depends on whether the bearing at the rear is in contact with the front part of the reducer.

The bearings are concentric.

"Okay, I'll confirm right away!"

Ju Xiaojie was very efficient here. He took out his phone and dialed the country, but the result was very pessimistic.

"Bastard, did you see the screenshot I sent you? How did a product of this quality enter the factory? Where is QE? The QC on site came out to me!"

Ju Xiaojie roared into the phone. On the other end of the phone, several leaders all had bitter faces and looked at each other. Many of them lowered their heads.

"Mr. Ju, this is not the time to hold people accountable..."

"I don't want to be held accountable. Where are the qualified parts I want? Who can I ask for them from? Our workers stand on top of a wind tower hundreds of meters high. A work ship costs 10,000 US dollars a day to berth! There is no dust seal.

The bearings will be exposed to the salt spray environment. Who is responsible for the problem? If I can't get accurate information within ten minutes and who will prepare qualified parts for me, then I will send an email to the headquarters to ask them

Help those bastards who only know how to sit in the office know what we are doing outside!"

"And go to the manufacturer right away to find out where this part is produced and what materials it is made of. Find our design drawings for me right away. I said right away, do you understand? Right now!!"

Ju Xiaojie shouted loudly into the phone, and several technicians on the other end of the phone immediately pulled out the drawings.

"Mr. Ju, I found it, the drawings are on the table!"

"Show me what the material is, and then show me what material the drawings issued to the outside require the product to be made of? Which version of the drawing is it? Which version of the drawing is the dust seal installed on our machine made according to?

I’ll give you five minutes, right now!”

"Received Mr. Ju!"

The designers did not dare to show any slightest care. From procurement to quality inspection in three minutes, all the people involved were pinned to their seats.

"Mr. Ju, our drawings have been updated to the fifth version, and the manufacturer's version is the fourth version! The material has not changed, and EPDM is required. We borrowed this product from German, so there will be no errors!

What is the problem?"

"Go to the manufacturer to confirm the formula of this product for me. The other time is coming soon. Where is the product from another company that I want? Our workers are on the wind tower. Do I want to work on it today? There will be a storm on the sea soon. It's time.

I can’t see my request coming true, someone has to take the responsibility, do you understand?”

Ju Xiaojie hung up the phone immediately as he said that. Ji Dongqing watched from a distance the whole time. Although he didn't hear what the other party said, he was very excited everywhere he saw it, and the other party's rights must be considerable, otherwise he wouldn't dare to look at those people who looked above his head.

The heavy technicians roared angrily.

The Dalian factory is already busy from top to bottom at this time. As for the Liujia factory in Ganjingzi, two Volkswagen staff are already in place.

"Where are your design drawings?"

"Leader, please wait a moment, we are looking for you, please wait a moment!"

"Why wait a minute, I've been here for half an hour, and you don't even know the drawings. This is how your technical department manages documents? Where is the technical manager?"

"Leader, please wait a moment. The technical manager is out and will be back soon!"

"Wait a moment. How big is your water trap? How many things can it hold? Where is Liu Yangxiang? Come out right away!"

…

The Liu family has a group of so-called ministers, managers, and general managers who are busy with their work.
