Chapter 2 Show your skills
Just when Yang Lei was about to board the folding body, he only heard Autoliv behind him say something to stop: "How can you be sure that what drips on the ground must be fuel, not lubricating oil or engine oil, and there is even the possibility of coolant." ”
Hearing this, Yang Lei stared at Autoliv like an idiot, exhaled, and said: "Dear Dean, if you must doubt my ability to judge these common senses, you might as well change the way, because this will make me think that you are an insult to my major, don't forget, when I joined SVO, I was still a student, and my major was the Department of Aircraft Warfare." ”
"And how do you prove it?" Autoliv spread his hands and said nonchalantly.
Rolling his eyes, Yang Lei thought to himself, he didn't look for him, this old immortal is now testing his bottom line, and then said: "There are no more than several common liquids inside the body, water, engine oil, coolant, brake fluid, and in addition, it is the crude oil filled in the fuel tank." ”
"Water is one of the most common liquids encountered in AC systems, and after condensation, the moisture in the air usually drips in the center of the body or at the air outlets on both sides, which is a normal phenomenon and there is no need to panic when it is found. The second, engine oil, is usually dark brown or black when ignited, depending on the quality of the oil. Yang Lei continued: "Engine oil and lubricating oil have a common effect, that is, to adjust the internal parts of the body, especially the steering joints, so as to avoid excessive friction index during the exercise to cause emergencies, they all have the pungent smell of rubber burning." ”
Sniffing his fingers, Yang Lei shook his head: "This, obviously not." However, it should be noted that in the manufacturing process, the engine oil should not be overfilled, and too much oil will be more disadvantageous than too little oil. ”
"It's even more impossible as for brake fluid and coolant, which is thin and slippery, and the coolant may be light green, pink, blue or even purple, but it will never be colorless like this! And often leaks occur only close to the engine or under the radiator. ”
After finishing speaking, the audience was silent, and even the academicians who were busy around various fantasy mecha before stopped what they were doing, staring at Yang Lei on the ladder like a monster, and couldn't take their eyes off it.
"Hey, I said, why is there a weirdo in our department again......"
"I don't know, it seems that the president recommended me to come in. I heard that I was still a student in school......"
"Is it true?"
In the face of the whispers below, Yang Lei felt very unaccustomed, was there any mistake, he just said something common-sense, can these people look at him with such eyes? You know, these were all given to him by Tutor Thomson in the maintenance department last semester.
At this time, Autoliv couldn't hold back his face, pretended to cough twice, and said no more, only Tang Yi watched with interest on the side, as if he had discovered a new continent on a map.
Seeing this, Yang Lei continued to mend the knife and said: "As we all know, the number one killer of mecha engines is coolant, because if the loss of coolant is too large, the temperature of the body will continue to rise, which will cause irreparable damage to the engine......"
"Bang Bang Bang ......"
Tang Yi took the lead in applauding, and then the entire R&D hall resounded with boundless applause for a minute, which undoubtedly satisfied someone's vanity.
"Okay, that's all for my explanation, I don't know if your old man is still satisfied?" Yang Lei looked at Autoliv indifferently and said with a smile: "If you still don't believe me, then there is just some left fuel here, you can taste it." ”
Just when Autoliv was about to refute angrily, Yang Lei didn't give him a chance at all, and said: "But I want to kindly remind you that this fresh liquid contains a lot of toxic substances, so you must not eat too much." ”
These words not only played a good role in provoking anger, but also made Yang Lei in the eyes of everyone to achieve a great image of not afraid of authority, in front of everyone's eyes, openly provoked the vice president, Yang Lei left a very deep impression on all the employees of the mecha special department, and everyone couldn't help but start to avoid it.
"Good, good!" Autoliv gritted his teeth and said, "Then I'll see how you solve it." ”
Glancing at Autoliv on the ground with contempt, Yang Lei turned around and climbed onto the folding body and came to the part where the engine was loaded under the cockpit. The situation of mecha fuel leakage is very dangerous, and its direct impact is the waste of crude oil, at present, there is a serious shortage of earth's resources, and various countries have successively introduced bills on mecha fuel control, so manufacturers are racking their brains to try their best to reduce fuel consumption standards, you know, the fuel consumption of a mecha is inconspicuous, but an army's can not be underestimated.
Not to mention the waste of resources, it is also possible that the engine will be damaged due to insufficient fuel, not due to oil leakage, but due to insufficient fuel pressure after the oil leak.
Thinking of this, Yang Lei immediately entered the cockpit, looked at the expected warning light prompt on the dashboard, and said with a smile: "Is the air pressure insufficient?" ”
After finding the key to the problem, Yang Lei quickly returned to the front of the engine, some oil leaks do not need to disassemble the cylinder block, but in the face of the oil leakage of the cylinder block part, it must be dismantled, because it is related to the personal safety of the pilot during driving, but fortunately, the source of the oil leakage of this wind walker does not appear inside the cylinder, so it is much simpler.
Found the toolbox that the Windwalker carried with him, climbed the ladder, Yang Lei opened the front hatch on his chest, and then used a brush to clean the oil covering the surface, in the process, he found that the liner that plays a role in leak-proof sealing between some static parts of the cabin has been damaged, if this is the case, it will not play a role in sealing and leak-proofing, and even safety accidents will occur.
Carefully tighten all kinds of fastening nuts in the entire engine compartment according to the torque specified in the standard, at this time Yang Lei was already tired and sweaty, or nervous, because it was too loose, it would not be able to compress the effect of the gasket, and leakage would still occur, and too tight would be the metal bulge around the screw hole or cause slippage.
In order to minimize the incidence of machine damage accidents, Yang Lei checked various valves on one side, such as check valves, ventilation valves, etc.
It was here that he discovered the hidden danger again.
After the ventilation system of the engine is blocked, it will cause the temperature in the fuel tank to rise, so that the oil and gas will fill the entire space and cannot be discharged, increase the movement resistance of the piston, increase the fuel consumption, and due to the effect of the air pressure difference between the inside and outside of the fuel tank, it will cause oil leakage in the weak sealing place, therefore, in order to prevent the engine fuel leakage, it is necessary to regularly inspect, dredge and clean the mecha.
However, this is usually the daily work of a maintenance technician, and now this high-end version of the Windranger has not yet officially entered the military mobile unit, so it is likely to be caused by the negligence of the operators, or brutal construction work.
"President, are you really so relieved of this kid?" Looking at Yang Lei's busy figure back and forth on the Windranger, Autoliv said: "In many cases, the mecha is not broken, but repaired!" ”
Tang Yiwei was silent, as if he was expecting something. (To be continued.) )
