James was a little embarrassed at this time. There was a professional reporter outside who was waiting for a joke. His troops were originally driven without fuel, but it was already very embarrassing. Now, the engine has also been released.
The failure was that I wanted to show the advanced nature of American tanks in front of the outside world, but now? It's a joke.
However, he had no other choice, and he still had to repair it. If he continued to pretend, he might really break the engine and the loss would be huge.
"Disassemble." James said.
So, just in front of everyone, the tank unit began to dismantle. Although other tank engines may be able to start, the overall situation is similar. Since some have fallen into bed, the rest should be replaced together.
It's gone.
Open the back cover and remove the air filter. Sure enough, the paper filter inside was completely blocked. It seems that they stopped here not entirely because of the bottom of the oil, but also because of the air filter.
The device is blocked.
"It's better to be inside the car." At this time, watching the Americans start to disassemble the engine, the few people did not get too close to them in order to avoid suspicion, but returned to the car. After entering the car, the air conditioner inside made people feel like
It was extremely refreshing and in sharp contrast to the outside. The outside was not a place to stay. After a few days, my skin was sunburned.
Nie Qianqian sighed and said, "We will have a desert topic this time. Should we write about technical issues in the desert?"
Of course, this is a question for Qin Zhenhua. After all, what can be written and what cannot be written depends entirely on Qin Zhenhua's decision.
"You can write it, after all, this is not confidential." Qin Zhenhua said: "A normal vehicle, when you arrive in the desert, it is not uncommon for frequent blockage of the engine's air inlet because of the strong wind and sand. Moreover, it is not uncommon for cars to use
Because of the large intake of gas turbines, this defect will be even more serious.”
I’m using the book-chasing app I’ve been using recently, [app] to cache reading and read offline!
When I got back in the car, I no longer had to install a foreign journalist. Several people communicated happily in the language of the Eastern power. Seeing the people outside working sweat profusely, it was so touching that they could blow the air conditioner and cool down.
I'm in a happy mood.
What Qin Zhenhua is talking about is also a defect of automotive gas turbines.
Compared to diesel engines, the intake of gas turbines has increased several times. If it is in an ordinary environment, it is nothing, but when it comes to the desert, there is wind and sand everywhere, and the sand is sucked into the engine, which is not fun.
The gas turbine has a speed of tens of thousands of revolutions. As long as one of them flies in it, it can break the engine. When the diesel engine sucks in, it is also a high probability that it will pull the cylinder and protect the machine's barrier, which is the air filter.
"If you run for hundreds of kilometers, you have to change the filter element. Otherwise, it would be fine if the filter element is blocked. If the filter element is broken and the sand falls into the engine, it is not a joke." Wang Erzhu also said from the side, at this time, he was from the car
, I can already see the other party starting to remove the air filter. The extra-large air filter looks very interesting when I take it out.
"So, how do we solve this problem with the equipment we exported to the desert?" Nie Qianqian continued to ask.
The Eastern powers exported a lot of weapons here. How did the large number of 69 tanks solve this problem in the armored forces of Iraq?
"In order to meet the needs here, we have specially developed a desert air filter." Qin Zhenhua said.
In order to sell the equipment here, the first machine factory has put in a lot of effort. It has made a lot of improvements to the tropical environment and a lot of improvements to the desert environment. This special air filter
, is one of them.
Ordinary air filters are paper-based. They are filtered through folded paper and filtered against the gap between paper molecules. The effect is very good. However, this is only suitable for normal environments. In the desert, countless sands are hit.
When it came to this layer of paper, it was blocked soon.
The special desert air filter uses a double-stage dry air filter composed of a multi-cyclone tube thick filter and a paper filter element, which means it uses double-insurance.
Before the paper filter element, a protection is added. When the air passes through the rough filter of the swirl tube, most of the dust is filtered out due to centrifugation and is introduced into the ash storage plate through the conical pipe. The filtered gas is
After passing through the inner tube of the cyclone, enter the next level of paper filter and then perform further filtration. The front and back channels are called coarse filtration and fine filtration respectively.
In this way, the sand and dust are mainly in the filter in front. This rough filter has a special ash storage tray. Most of the sand is filtered on the ash storage tray, so that it can be poured out directly. It is very convenient, only a few
The sand will enter the fine filter, greatly increasing the use of paper filter elements.
"After using it for a long time, the front coarse filter will also fail. At this time, you can take out the filter net, blow it with high-pressure air, and then put it in. This method greatly reduces maintenance and maintenance
"The cost of this device is very reliable in the hands of users in Yiguo."
The Americans have not specifically studied and experimented, so they are blind now. They are still using paper filters, which is simply a waste of resources.
"Is there any disadvantage?" Nie Qianqian asked.
"There are also disadvantages. The biggest disadvantage is that the intake resistance increases and the appearance size is also large. However, as long as we pay more attention to the design, we can reduce the resistance to the allowable range." Wang Erzhu said.
When exports started, Wang Erzhu was also the main force in technological innovation, and the design of air filters was his main recommendation.
Nie Qianqian's eyes rolled twice, and then said, "So, do we have the ability to modify air filters for Americans? This will make them a lot of money?"
"Qianqian, you have been following Brother Zhenhua for a long time and have also begun to learn to think about problems in his way." At this moment, Wang Xiaoyu, who had not spoken much, spoke.
Qin Zhenhua always thinks about how to make money. Now, Nie Qianqian has also learned it?
"It's not difficult to modify it for Americans. As long as we know the intake flow of their engines and the maximum space that the air filter can occupy, we can design it." Qin Zhenhua said: "Using domestic design, one day
You can produce the finished product.”
This thing is just a matter of thinking, and it is not difficult to produce it in real way.
"Okay, then I'll go and fool us, maybe I can also fool us into making a business." Nie Qianqian said.
