Chapter 750: Mouthy
Blowtorch is a common tool, using a jet flame to heat the workpiece, in the interior of a machine factory, heating the soldering iron during welding, baking sand mold during casting, heating the workpiece during heat treatment, etc., are used.
Therefore, a skilled worker can use the blowtorch to do all kinds of things in a chic and natural way, and now, Qin Zhenhua, a technical expert who has come up from the bottom little by little, is even more chic and free to use the blowtorch, he operates the blowtorch, and slowly heats a circle of steel around the turret, and after the heat is transferred, Staff Officer Wang's hand is finally taken down from the turret.
At this time, Staff Officer Wang's face was ugly, in front of everyone, there was such a big ugly, and in front of He Lao and others, it was even more uncomfortable, but he had no way to complain about others, he reached out himself.
"This turret has a relationship with Counselor Wang." He Lao said there: "As soon as we met, we shook hands, and we shook them, and I was reluctant to part." ”
And so everyone laughed.
"It's freezing on this day, is it easy to start the engine?" Just then, another person asked.
The use of blowtorch is many, in the army, the car soldiers are also equipped with blowtorches, in winter, the car is not easy to ignite, all rely on this blowtorch to bake.
In the country, it is enough to bake only the engine, if you go to the USSR, in that kind of cold weather, even the wheels have to be baked, because after a night, the wheels and the ground will freeze!
Now, hearing this question, Qin Zhenhua said with a smile: "In this regard, I really have to admire the skills of the Germans, two pillars, go up and start the tank." ”
This 1226 tank, still using the German 331 engine, uses a hydraulic gearbox, to achieve steering wheel control, at the same time, the engine compartment is longitudinal, compared with the previous transverse, the back is much longer.
This is also the reason why the 1226 tank is much heavier than the 1224 tank, the hull is lengthened, and the weight naturally comes up.
This is, of course, to realize the overall hoisting of the engine compartment, which is still a novel attempt in China.
Now, everyone thought of another thing from the embarrassment of Staff Officer Wang, this diesel engine is not easy to start in the cold weather!
Gasoline vehicles rely on spark plugs to ignite fuel, while diesel engines are compression ignition, pressed to a certain extent, the temperature of the air will rise to the most sufficient degree for diesel combustion, so the diesel is injected into it and burns directly.
In this way, the diesel engine has a high compression ratio, which is also the reason for the strength of the diesel engine, however, this also brings another problem, in the cold weather, if you want to start the diesel engine, it is not easy, the diesel can not be pressed, it will always emit black smoke.
At the same time, at low temperatures, diesel fuel will also wax and clog the oil pipe, especially in the impure diesel oil, there may also be moisture, causing the oil pipe to freeze, blocking and completely unable to start.
The method used is to use a blowtorch to heat, which is also a helpless thing.
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 his body was flexible, and after entering, he made a fuss.
One minute, two minutes, three minutes, nothing at all.
"Hey, why haven't you 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 warm-up light turned red and he twisted the start knob.
"Teng Teng." The sound of an air motor came from the tail, and under the impetus of high-pressure air, the diesel engine of the tank spun up, and after a few puffs of black smoke came out, the sonorous sound of the engine came.
Is it so simple that the launch was successful?
In winter, the power stored in the battery will also decline, so it is quite inconvenient to use the battery to start the vehicle in winter, as for the kind of electric car in later generations, if it goes to the cold area, it will be even more cheating, not to mention the electric car, an Apple mobile phone, originally fully charged, to the cold outside, it will automatically shut down because of the loss of power, not to mention the electric car.
Whether it is a lead-acid battery or a lithium battery, this characteristic is impossible to change, and the low temperature makes the activity of the chemical reaction naturally poor.
Of course, the wisdom of the people is endless, in order to solve the problem of electric vehicles in winter, some people have put forward a plan, since the temperature is low, then I will go to a heater! Just heat up the battery, and by the way, heat the car.
Where does the energy for heating come from? Fuel tank, let's set up another fuel tank! I'm still a new energy source, because the fuel tank is heated hard, and nothing else.
Tank start, can be started with electric and compressed air, in winter, or compressed air start method is more reliable, at the same time, just waiting for a few minutes, is in the preheating, this engine, taking into account the winter start problem, has been added at the top of the cylinder, a set of preheating plugs, preheating in advance.
As for the problem of fuel, in this weather, it is minus fifty diesel fuel added, which is enough to be used in the weather of minus forty or fifty degrees.
How is the performance, it is not how much data is blown out, but displayed, now, listening to the sound of the engine starting, everyone is nodding, the tanks in the army, in fact, also rely on the roasting fire, in the cold winter, this is almost the only way.
What about people? People go up for a few minutes, and it starts directly, this is the gap!
"The performance of this German diesel engine is still very good, and where its design is advanced, we are constantly learning, and then use it in our own engine." Qin Zhenhua said: "Of course, if you want to talk about the starting ability in severe cold conditions, it is always the gas turbine that has the advantage. ”
The piston engine can never be compared with the gas turbine, and people don't need to preheat it, and they can be brought up directly, but this kind of engine can't be played in China.
Even if it is made, it will not be able to burn oil, except for the Americans and the Soviets, who can afford it?
Qin Zhenhua was thinking like this, when he heard He Lao speak: "Yes, gas turbines have innate advantages in this regard, and now, the M1 tanks of the United States and the T-80 tanks of the Soviets have begun to use gas turbines, does this mean that the power development direction of tanks in the future is gas turbines?" Although our country is short of funds, the technology that should be pre-researched should also be invested. ”
Hearing this, Qin Zhenhua instantly froze, he is a straight person, he can say whatever he wants, it seems that this is not good, and he has to change it.
