Chapter 8: Repairman

The conditions of the oil production team, the communication is completely dependent on roaring, and the voice of the repairman Lao Wu is at least equivalent to the "most dazzling national style" of two copycat mobile phones at the same time, and the transmission distance is more than 100 meters.

Su Cheng straightened up and said with an innocent expression, "I think the screws on the base are loose, and I tighten it."

"The screws on the base have a head." Lao Wu was too nervous just now. After walking over, his tone calmed down a little and said, "You are too tight. The donkey's head is up and down. After a long time, you have to loosen other screws? If the screw is loose and the donkey's head falls off, it will be a big deal.

As he said, he pulled out the wrench from his waist, put it on the screw, and loosened it again and again, but it was a "huh".

A 20-year-old quigrew like him, when the wrench moves, he knows whether the screw is loose or tight, which is more effective than any test equipment. The tens of thousands of oil extractors in Shengli Oilfield, thousands of inspection tasks per week, and hundreds of maintenance tasks are all built by such senior workers by hand.

To Lao Wu's surprise, he clearly saw that Su Cheng screwed the screw, but when he started it, the screw was just right. So he tightened it and relaxed again.

As soon as the artist took action, he knew if there was any. Lao Wu verified it carefully, and stood up and sighed, "College students are good, learn machinery?"

"No, I've seen it a little bit." Su Cheng smiled. At the end of his internship, he went to find a job, and then crossed into this era, holding a wrench, and felt quite familiar.

Lao Wu didn't think much about it and said, "It's a little like it."

"What's going on?" Captain Dou Wanshan heard the shout and climbed out of the well.

"College students will repair the machine. The base was loose just now, and he saw it out." Lao Wu's apprentice is only 17 years old and has a lively nature. He is eager to do something every day, and now he can't stand it.

Dou Wanshan couldn't help looking at Lao Wu.

The latter nodded and said, "I saw that he circled around and put the wrench on the screw, and then he roared."

"If the machine is stopped, can you see that the base is loose?" The old workers present recognized the key as soon as they heard it.

Su Cheng said with a simple smile, "I happened to compare the bullet line. I found that there was a deviation, so I corrected it."

"How did you think of the bullet line?"

"I saw that you all went down to the well, and you just walked around the edge of the kowtow machine. It's idle." Su Cheng said it in a word. It is indeed a subconscious behavior for him to check the bullet line, but the cultivation of this behavior has been systematically cultivated and educated.

In the serious oil production machinery maintenance tutorial, ancient products such as beam pumping units have long been poorly studied. If there is a problem in any part, there are corresponding inspection items, such as the vibration of the pumping unit. The impact load, connecting screws, chassis or foundation suspension should be checked. In 1987, some state-owned enterprises may have such research results, but they are mostly used in their own small circles, specifically at the grass-roots level, relying on the master's experience.

Su Cheng doesn't know if there is a systematic maintenance manual now, so he uses an asse to replace it.

Lao Wu shook his head with emotion and said, "I've been in Jingzhan for 20 years, and I didn't want to see the bullet line just now."

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

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

While he was talking, he opened the oil tank of the gearbox and removed it.

In such a large box, lubricating oil and crude oil are mixed together, and there are rags, sand and bricks faintly below.

"How can there be a brick?" Su City was immediately in a mess.

"This is not enough oil surface. Throwing something in can improve the liquid level. Last time, Xiaohei just picked up two bricks..." Lao Wu said naturally.

Su Cheng's eyes widened: "Did you lose it?"

"That's not nonsense."

"What's wrong with the rags and crude oil in it?" Su Cheng took a stick and stirred it twice in the gearbox. If it is not to say that the beam pump is easy to maintain, the gears work in this environment for more than ten years, and the good oil bath lubrication has also turned into a Gobi bath.

Xiao Hei, Lao Wu's apprentice, laughed and said, "It's also me."

"In order to improve the liquid level?"

"Afraid of stealing." Xiaohei said it very simply.

In the 1980s, it was the time when fuel consumption began to appear, but it was the most rampant. Throughout the Bohai Bay, there are local fuel consumption and foreign oil mice. Lubricating oil is a very expensive thing. If it is sold in stores, one catty of lubricating oil can be up to two catties of vegetable oil. There are tens of thousands of oil extractor in the oil field, and it is not difficult for them to steal them. If the lubricating oil is mixed with crude oil, it will not be sold for a price. Although the reducer will suffer a certain amount of wear, it is much less than the wear caused by theft of oil.

Lao Wu lowered the oil surface and asked, "Look, how about this gear?"

"There is no wear and fracture, and there is no tooth surface pitting and peeling..." The little black monster said, "Uh-huh" and said, "It's strange. The gears are fine. Why doesn't the gearbox work?"

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

Lao Wu has been paying attention to him. At this time, the corners of his mouth smiled and said, "Xiao Su, tell me about it."

"It's a series of axes. Since there is no broken tooth, it should be that the driven wheel of the intermediate shaft and the fastener of the shaft should be loose. Su Cheng did not make actual measurements, but judged completely based on book knowledge.

Xiaohei immediately went to check and found the loose part. He couldn't help but be surprised and said, "How do you know?"

Su Cheng shrugged his shoulders and didn't know how to explain it. This maintenance method is actually very common. For example, telecommunications network engineers can guide users to solve problems over the phone. Zooming in to the factory equipment, a video conference can also save several tickets.

In fact, they are not skilled, but good at standard procedures.

Mature products should have mature maintenance guidelines, analyze all possibilities according to the appearance, and then exclude and screen them. However, China does not pursue single-person efficiency during this period, nor does it have the energy to spend time on employee training. When the master leads the apprentice, he can often bring out high-level and comprehension senior workers, but the time will be delayed for a long time.

No matter where Su Cheng learned the technology, Lao Wu Cai patted his hand with engine oil on the shoulder and shouted with a smile, "Our team has made money. There is a big worker."
