super energy power

The conditions of the oil production team depend entirely on roaring for communication, and the voice of maintenance worker Lao Wu is at least equivalent to two knockoff mobile phones playing "the most dazzling national style" at the same time, with a transmission distance of over [-] meters. ┏ _ ┓

Su Cheng straightened up, showing an innocent expression, and said, "I see that the screw on the base is loose, so tighten it up."

"The screws on the base have heads." Old Wu was too nervous just now, but when he came over, his tone became calmer, and he said: "You are tightening too tightly, the head of the donkey is going up and down, it has been a long time, don't put another Are the screws loose? If the screws loosen and the donkey’s head falls off, something serious will happen.”

As he spoke, he pulled out the wrench from his waist, stepped forward and put it on the screw, twisted and loosened, but there was a sound of "Huh".

An experienced mechanic like him can tell whether a screw is loose or tight with the flick of a wrench, which is more effective than any testing equipment.The tens of thousands of oil extraction machines in Shengli Oilfield, the inspection tasks of thousands of machines, and the maintenance tasks of hundreds of machines every week are all built by such senior workers.

What surprised Old Wu was that he clearly saw Su Cheng turn the screw, but when he started to do it himself, the screw was just tight enough.So he tightened it and then loosened it.

As soon as the expert makes a move, he will know whether it is there or not. Old Wu carefully verified it again, stood up and said with emotion: "A college student is not bad, a mechanical student?"

"No, I've seen it a little bit." Su Cheng smiled.After his internship, he went to find a job, and then traveled to this era, holding a wrench, and still felt quite familiar.

Old Wu didn't think much about it, and said, "It looks a bit like that."

"What's going on?" Dou Wanshan, the captain, heard the shout and crawled out from the well.

"College students know how to repair the machine. Just now, the base was loose, and he saw it." Lao Wu's apprentice is only 17 years old, and has a lively personality.

Dou Wanshan couldn't help but glanced at Old Wu.

The latter nodded and said, "I saw him go around and put a wrench on the screw, and then he yelled."

"You can see that the base is loose even when the machine is stopped?" The old worker present heard the key point.

Su Cheng smiled honestly: "I happened to compare the elastic thread, and found that there was a deviation, so I straightened it."

"How did you come up with the idea of ​​snapping the thread?"

"I see that you all went down the well, so you wandered around the kowtow machine for a while, and you're free." Su Cheng said casually.It is indeed a subconscious behavior for him to check the thread, but the cultivation of this behavior has been systematically cultivated and educated.

In the serious maintenance course of oil production machinery, ancient products such as beam pumping units have long been researched and rotten.If there is a problem in any part, there are corresponding inspection items. For example, if the pumping unit vibrates, you should check the impact load, connecting screws, chassis or foundation suspension.In 1987, some state-owned enterprises may have such research results, but they were mostly used in their own small circles. When it comes to the grassroots, it is ultimately based on the experience and judgment of the old masters.

Su Cheng didn't know if there was a system maintenance manual, so he used excuses instead.

Old Wu shook his head emotionally, and said, "I've been in Jingzhan for a year, and I didn't think about going to see the thread just now."

"Xiao Su is a college student." Dou Wanshan wiped his face and went down the well again.

Old Wu greeted Su Cheng and said, "Come on, let's go check the gearbox together."

While he was speaking, he opened the oil tank of the gearbox and took the inside out.

In the huge box, lubricating oil and crude oil are mixed together, and there are faintly rags, sand and bricks underneath.

"How could there be bricks?" Su Cheng was in a mess immediately.

"It's because the oil level is not enough. Throwing something in it can increase the liquid level. Last time, Xiao Hei just picked up two bricks..." Old Wu said very naturally.

Su Cheng's eyes widened: "You lost it?"

"This is not nonsense."

"What about the rags and crude oil in there?" Su Cheng took a stick and stirred it twice in the reduction box. Besides, the beam pumping unit is easy to maintain, and the gears are in this environment I have been working for more than ten years, and a good oil bath lubrication has also become a Gobi bath.

Old Wu's apprentice, Xiao Hei, chuckled twice, and said, "It was also me who poured it."

"To raise the fluid level?"

"Afraid of stealing." Xiao Hei said very simply.

The 80s was the time when oil rats just started to appear, but they were the most rampant.Throughout the Bohai Bay, there are local oil rats and foreign oil rats.Lubricating oil is very expensive. If it is sold in a store, one catty of lubricating oil is worth two catties of vegetable oil.There are tens of thousands of oil extraction machines in the oil field, and it is not difficult for others to steal them.If lubricating oil is mixed with crude oil, it will not be sold at a price. Although the reducer will suffer certain wear and tear, it is much less than the wear caused by oil being stolen.

Old Wu lowered the oil level and asked, "Look, how about this gear?"

"There is no wear and tear, and there is no pitting and peeling of the tooth surface..." Xiao Hei gave a strange "hmm" and said: "This is still strange, the gears are fine, why the reduction box can't work."

Su Cheng recalled what he had learned, but focused on the axis.

Old Wu had been paying attention to him, and now a smile appeared on the corner of his mouth, and he said, "Xiao Su, tell me."

"It's a string shaft. Since there are no broken teeth, it should be that the driven wheel of the intermediate shaft and the fastener of the shaft are loose." Su Cheng didn't actually measure it, but judged it entirely based on book knowledge.

Xiao Hei went to check immediately, and found the loose parts. He couldn't help being surprised, "How do you know?"

Su Cheng shrugged, not knowing how to explain.This kind of maintenance method is actually very common. For example, a telecom network engineer can guide users to solve problems on the phone.Zooming in to factory equipment, a video conference can also save several air tickets.

In fact, they are not improving their skills, but doing well in standard procedures.

Mature products should have mature maintenance guides, analyze all possibilities according to the appearance, and then perform exclusion screening.However, China in this period did not pursue single-person efficiency, nor did it have the energy to spend time on employee training.When a master leads an apprentice, he can often bring out a high-level and savvy senior worker, but it will take a long time.

Old Wu didn't care where Su Cheng learned the technology, and patted his shoulder with a hand mixed with engine oil, and shouted with a smile: "Our team has made money, and a great job has come."
