"I really didn't expect that the field tank emergency repair vehicle brought by this really played a big role." At this time, in the cab of the Type 90 tank modified emergency repair tractor, Qin Zhenhua was stepping on the accelerator pedal and starting the operation.
The emergency tractor advances, and behind it, drags the 85-3 tank with a steel cable.
Qin Zhenhua was a little ridiculous and self-deprecating when he was talking. When he came, he decided to bring this car over, not to do this. Every day, he would drag an 85-3 tank back after the test. This is called
What happened? Yesterday's first time was an accident, but today it was definitely a mechanical failure.
Qin Zhenhua said, while glanced at Wang Erzhu sitting behind him. At this time, Wang Erzhu had closed his eyes and showed a painful expression on his face. He failed again today, and had an accident again today, and wanted to chase T-80UD
The tank points are almost even more difficult.
Wang Erzhu was full of self-blame. In his eyes, it was mainly because of his personal reasons. Although it was not actually caused by him, Wang Erzhu would not forgive himself.
Qin Zhenhua said this to make fun of Wang Erzhu, hoping that Wang Erzhu can recover. Unfortunately, Wang Erzhu obviously did not have that mood.
So Qin Zhenhua stopped talking, started the tank repair car, and rumbling back to the starting point.
At this time, a large number of Pakistani personnel had already surrounded him. Aslam said: "Would you like to drive back to our tank overhaul factory, where there is enough equipment to complete the emergency repair of the tank."
Aslam trusts the products of the Eastern powers. After all, the 85 tanks that are being produced in their factory are of good quality and have never had a power system failure. Today, this situation is really unexpected, and the conditions in the wild are not
OK, if you start to the overhaul factory, you will be more relaxed in repairing.
"No need, it's too late to go back and forth." Qin Zhenhua said: "We have repaired it on site. Now, let's lift the engine first."
Today's failure is clearly a problem with the engine and transmission system, so they must hoist the power unit. It cannot be repaired inside the tank, so they can only lift it out for repair.
Unfortunately, I missed some of it. If I brought an extra set of power units when I came here this time, I could replace it at any time. This power unit is specially designed and in the wild.
, can also be quickly hoisted.
"We have technicians, and we can help you anytime," Aslam said. "We are very familiar with the engines of the Eastern Powers..."
"Thank you." Qin Zhenhua said: "We may need some parts. If you have one there, I hope we can deliver them to us quickly."
Pakistan has the ability to overhaul the engine, so they also store some spare parts. These engines are common and many parts can be replaced. Now, there is no other way. It is arranged from China. It is absolutely
It's too late, so I can only ask for help here.
The book friends used the small book pavilion before.
"No problem, what parts do you need?" Aslam asked.
"This will only be known after it is taken apart." Qin Zhenhua said: "Today's power system failure is insufficient power and black smoke is emitted. It is very likely that the valve is not tight, and it may only be necessary to polish the valve, but if it is complicated, it is
, the cylinder piston and other things may need to be replaced."
Before it is removed, it can only be inferred based on experience that the valve acts as intake and exhaust, and is quite precise. After running for a period of time, the valve may wear out and cannot be closed, and the cylinder will leak.
At this time, the motivation must be reduced.
Just as Qin Zhenhua was talking, the engine had been hung up and placed on the engine bracket beside him. The experienced old technicians from the first machine factory immediately began to dismantle, with buzzing sounds endlessly.
, the cylinder head was removed.
When the cylinder head was removed, everyone was stunned: "Impossible, why is this happening?"
Inside the cylinder head, you can see valves, which are not closed tightly. From the valve part, you can see a layer of black things. Everyone is familiar with the thing, and it is carbon accumulation.
If the engine is not completely burned, carbon deposits will form in the combustion chamber. This is a common phenomenon. Everyone knows that no matter how the engine technology develops, carbon deposits will not be eliminated. In later generations, direct injection of engines in the cylinder will be carried out.
Carbon deposits are even more serious.
But, there is a limit. Now, the carbon deposit is so deep that it actually pushes up the valve?
Then, looking into the cylinder, I saw that it was pitch black, the cylinder wall had been strained, and there was a thick layer of carbon deposits on the top of the piston. Judging from it, it was probably one or two centimeters thick! In this case, the engine was still
Want to output power? It’s hard to maintain your own operation!
"Impossible, impossible, there must be something wrong, there must be something wrong!" Wang Erzhu said: "This is impossible for our engine. It is impossible for such a serious carbon deposit!"
The tank engine produced by the first machine factory may be insufficient power, only one thousand horsepower, and cannot be compared with an engine with one thousand two hundred horsepower. However, the reliability is absolutely guaranteed, and such a serious problem cannot occur!
Qin Zhenhua also frowned. Wang Erzhu said exactly what he guessed. This engine was simply damaged. Such a serious carbon deposit would not be possible even if it was running for a thousand hours in a row.
result.
"Everyone, please disturb me, do you need help? We also have very excellent engine experts." At this moment, a voice sounded from behind: "The problem of carbon deposits in the engine may be that the fuel supply has been rashly increased, but
No other parameters have been changed, and the incomplete combustion of diesel injected into the cylinder has been caused by the incomplete combustion of the diesel oil."
The voice of Wang Erzhu sounded a little annoyed. Although the other party was very sincere, it seemed to be deliberately ridiculing him in his ears. Wang Erzhu replied coldly: "No need, our engine, we
Know it yourself!"
Humph, what good people are you going to pretend to be? If you really want to be a good person, why did you still steal our business? Especially, we recommend you, but in the end, it was too much to steal our business!
"Mr. Aslam, we need a complete set of pistons and cylinders, please send them to us immediately." Qin Zhenhua is already arranging accessories.
