Blowing lamps are a common tool that uses spray flame to heat the workpiece, heat the soldering iron during welding, bake sand during casting, heat workpiece during heat treatment, etc., all of which are used.
Therefore, a skilled worker can use blowtorch naturally to do all kinds of things. Now, Qin Zhenhua, a technical expert who has come up little by little from the bottom, is extremely free and easy to use blowtorch. He operates blowtorch.
He slowly heated a circle of steel around the turret. After passing the heat over, Staff Wang's hand finally took it off the turret.
At this time, Staff Wang's face looked ugly. In front of everyone, such a big ugly person was even more uncomfortable in front of Mr. He and others. However, he could not blame others.
He reached out to him.
"Is this turret a fate with Staff Wang?" Mr. He said there: "When I met, I shook hands and held them, I still can't bear to part."
So everyone laughed.
"It's cold and cold, is it easy to start the engine?" At this moment, another person asked.
Blowing-ups have many uses. In the army, the car soldiers are also equipped with blowtorches. In winter, cars are not easy to ignite, and they rely on this blowtorch to bake them.
In China, you can only roast the engine. If you arrive in the Soviet Union, even the wheels have to be roasted in the cold weather, because after a night, the wheels and the ground will freeze!
Now, after hearing this question, Qin Zhenhua smiled and said, "In this regard, I really admire the German technology. Second pillar, go up and start the tank."
This 1226 tank uses a German 331 engine and a hydraulic transmission to achieve steering wheel control. At the same time, the engine compartment is longitudinal, which is much longer than the previous horizontal configuration.
This is also the reason why the 1226 tank is much heavier than the 1224 tank. If the body is longer, the weight will naturally increase.
This is of course to achieve the overall lifting of the engine compartment. In China, this is a novel attempt.
Now, everyone thought of another thing from the embarrassment of Staff Wang. This diesel engine is not easy to start in the cold weather!
Gasoline cars ignite fuel by spark plugs, while diesel engines ignite. When pressed to a certain level, the temperature of the air will rise to the level that is most sufficient for diesel to burn, so when the diesel is injected in, it will burn directly.
This method gives the diesel engine a high compression ratio, which is also the reason why the diesel engine is strong. However, this also brings other problems. In cold weather, it is not easy to start the diesel engine.
If the diesel is not pressed, black smoke will continue to emerge.
At the same time, diesel will also become waxy at low temperatures, blocking the oil pipe. Especially in the impure diesel, there may be moisture, causing the oil pipe to freeze and block it and it will not be started.
The method to use is to use a blowtorch to heat it, which is also impossible.
And now, the big guy watched Wang Erzhu climb into the cockpit in front. He was wearing a pair of white gloves for work and had a flexible body. After entering, he started to tinker.
One minute, two minutes, three minutes, nothing is going on.
"Hey, why haven't it started yet?" someone asked Wang Erzhu.
Wang Erzhu lowered his head, looked at the indicator light inside, and said, "Wait a minute, wait a minute!"
Finally, the preheating indicator light turned red and he turned the start knob.
"Tengteng." The sound of an aerodynamic motor came from the tail. Driven by high-pressure air, the tank's diesel engine rotated. After a few black smoke came out, the powerful sound of the engine came.
It's so simple, is it started successfully?
In the severe cold winter, the battery power will also drop, so it is quite inconvenient to start the vehicle with a battery in winter. As for the electric vehicles of later generations, if they reach a cold area, it will be even more a scam, not to mention electric vehicles.
An Apple phone was originally full of electricity, but when it was taken outside in the cold, it turned off automatically because it was out of power, let alone electric cars.
Whether it is a lead-acid battery or a lithium battery, this characteristic cannot be changed. If the temperature is low, the activity of chemical reactions will naturally be poor.
Of course, the wisdom of the people is endless. In order to solve the problem of electric vehicles in winter, some people have proposed a plan. Since the temperature is caused by low, I will use a heater! Just heat the battery.
, and can also heat the car.
Where does the heating energy come from? Fuel tank, let’s set up another fuel tank! My new energy is the same because the fuel tank is heated vigorously and does not do anything else.
The tank can be started with electric start and compressed air. In winter, the starting method of compressed air is more reliable. At the same time, the few minutes I just waited for is preheating. This kind of engine takes into account the starting problem in winter.
, A set of preheating plugs has been added to the top of the cylinder to preheat in advance.
As for the oil problem, in this weather, the diesel of minus fifty is added, which is enough to be used in weather of minus forty or fifty degrees.
How good the performance is not how much data is blown out, but how it is displayed. Now, listening to the sound of the engine starting up, everyone nodded. The tanks in the army are actually mainly based on fire, in the cold winter,
This is almost the only way.
What about them? They go up for a few minutes and start it up directly. This is the difference!
"This German diesel engine has very good performance. We are constantly learning about its advanced design and then using it on our own engines." Qin Zhenhua said: "Of course, I have to say that in the severe cold conditions.
The startup capability is always the advantage of gas turbines.”
Piston-type engines can never be compared with gas turbines. They don’t need to warm up, but they can be brought up directly. However, this kind of engine cannot be used in China.
Even if it is made, it cannot be burned. Who can afford it except the Americans and the Soviets?
Qin Zhenhua was thinking this way, and he heard Mr. He speak: "Yes, gas turbines have inherent advantages in this regard. Now, the American M1 tanks and the Soviet T-80 tanks have begun to use gas turbines.
, Does this mean that the future direction of tank power development will be gas turbines? Although our country is short of funds, we need to invest in the technology that should be pre-researched and what should be invested."
Hearing this, Qin Zhenhua was stunned. He was straightforward and said whatever he had. It seemed that this was not good and he had to change it.
