Five hundred and fortieth chapters careless assembly
"It seems that this problem is not because the strength of the pipe is not enough." Wu Ruihua came from a branch factory, looked at the pipe that had a big hole cracked behind him, and frowned.
In fact, the original tube was already very strong last time. According to calculations, the pressure it was under was strong enough. After the first explosion, everyone's most direct speculation was that the strength was not enough and continued to strengthen.
, and now, it has failed.
The technicians from the coal province diesel engine factory just slapped their butts, leaving a machine factory behind, which also wanted to solve the problem.
Wu Ruihua looked at the broken tube and kept thinking about solutions to the problem in his mind.
"What happened?" At this moment, Qin Zhenhua also came over.
He came out of the welding workshop. Every day, he would personally take the test with Lu Feng, experiment a few times, and then test to see if the strength and other requirements meet the requirements, and then study the new welding process. Every time he came out, he would feel that he would feel that he would
It feels uncomfortable to hold it in your lungs.
Welders are also a job that has a great impact on the body. Even in the hotter weather, they have to cover themselves tightly. If the welding flowers fall on their body, they will become hot and bubbled.
Over time, skin problems will occur.
If you don't protect yourself, if your eyes come into contact with too much light, you will be injured, and the ultraviolet rays inside will be too strong.
Of course, the biggest problem is the smoke, the welding wire melts, and the welding medicine helps to weld it, and it will also evaporate a irritating smell. Over time, too much inhalation into the lungs will make you feel very uncomfortable.
Now, Qin Zhenhua was breathing the air outside in big mouthfuls while watching what was happening here.
"It's strange that there is no problem with our Storm tank. As a result, when we arrived at this 80 tank, we started to make trouble." Li Changjiang said: "There must be some problems here that we don't know."
It makes sense that the people from the coal-provincial diesel engine factory have left. In the eyes of others, it seems that the test drive on the bench is fine, but it will break down when it arrives here. It is not their reason, but the tank.
Of course, this uncooperational attitude is more psychological. If the other party has psychological resistance, it will naturally not be truly integrated here.
"Yes, we have to compare." Qin Zhenhua said: "Master Zhang, do you think there is any difference between these two tanks when you were testing the drive?"
Zhang Xiangqian recalled it seriously, and then said with certainty: "This tank feels more noise when it moves."
When it was originally designed, the two chassis were actually similar. As a result, the tanks here were more noise. What does this mean?
Qin Zhenhua thought quickly in his mind. Suddenly, his eyes opened and he said, "Open the engine and let's see how it vibrates."
Why does the noise increase in tanks? The sound is all caused by vibration. This increase in noise may be caused by the increase in engine vibration.
"But, the supercharger's tube has cracked." Someone said, "Do we need to change the tube?"
"No, the tube is broken, that's a self-priming engine." Qin Zhenhua said: "Idle first, let's see the situation."
The turbocharged engine relies on exhaust to push the blades, which drives the fan to suck more air in. At idle speed, the exhaust pressure is not enough, so the engine cannot absorb more air, which means
The turbocharger with the engine does not work. At this time, it is just a naturally aspirated engine, which is quite simple.
Now, Qin Zhenhua asked him to idle first to see the situation. Zhang Xiangqian came to the cockpit in front. The engine started up amid the sound of the compressed air starter.
The moment I started, I saw the engine as if it was on a trampoline, buzzing and shaking up and down the ground. The shaking movement was so strong that it was like jumping
Like dancing.
As the engine vibrated, the broken trachea was also shaking violently.
It's clear at a glance.
This tube was not exploded by too much pressure, but was shaken open because of too much vibration!
If this is a three-cylinder engine, then the congenital unevenness causes it to vibrate so violently, that's fine. The problem is, this is a V12 engine, and the smoothness of this engine should be quite good.
.
"Prepare the crane and lift the engine, the problem should be on the rubber pad of the engine bracket." Wu Ruihua said.
They are all masters, and you can see the key to the problem at a glance. The reason why the engine vibration is so huge is that when assembling, the rubber pads on the engine bracket below were originally broken!
As long as the engine is started, it will vibrate. In order to avoid transmitting the vibration to the engine, the engine and the vehicle body are not rigidly connected. The engine is fixed by foot bolts, and a thick rubber gasket is connected in series between the foot bolts.
, this gasket can reduce vibration.
This tank was assembled by the people in the R&D room. Everyone is not sure how they assembled. Since it has been assembled, it has not moved much. Now, when Wu Ruihua judged that it was below.
When the rubber pad was problem, Zhang Xiangqian had already lie in and observed the situation below. Sure enough, he soon saw the problem. Among the eight anchor screws fixed below, there were two rubber pads with thickness and other ones.
Obviously different!
"How do these people work!" Seeing this situation, everyone couldn't help but look angry. Such a small mistake would cause big trouble. If Qin Zhenhua hadn't studied it carefully, it would have been a long time for everyone to find it.
The cause of the failure lies!
When producing and assembling, a small problem can also lead to consequences. These people are careless and cannot do anything authentic!
The engine was not fully lifted and did not follow the original design idea. Therefore, changing to such a small rubber pad became a problem. Everyone was hungry and fought until four o'clock in the afternoon. They finally changed.
, At this time, Jin Yonglin and others were late.
"Hmph, these people are simply a waste of food from our machine factory. It's better to just send them back. Anyway, when there is a problem, they won't work with us to find a way to solve it." Someone looked at him with dissatisfaction
Looking at those people, he complained in a low voice.
Qin Zhenhua's eyes became extremely serious. He saw that the arms of these people were wearing an exquisitely shaped electronic watch!
