The conditions for the oil production team are that communication depends entirely on yelling. The maintenance worker Lao Wu's voice is at least equivalent to two copycat mobile phones playing the "most dazzling national style" at the same time, and the spreading distance is over 100 meters.

Su Cheng straightened his waist and showed an innocent expression, "I saw that the screws on the base were loose and tightened them."

"The screws on the base are said to be the head." Old Wu was too nervous just now. After walking over, his tone calmed down and said, "You are too tight, and the donkey's head is up and down. After a long time, you must not loosen other screws? If the screws are loose and the donkey's head falls off, something big will happen."

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

Mechanics like him who have 20 years of work experience will know whether the screws are loose or tight as soon as they move the wrench, which is more effective than any testing equipment. Tens of thousands of oil production machines in Shengli Oilfield, thousands of inspection tasks and hundreds of maintenance tasks are all built by such senior workers with their hands.

What surprised Old Wu was that he clearly saw Su Cheng twisting the screws, but when he started to use it, the screws were tight just right. So he tightened them and relaxed them again.

As soon as an expert took action, he knew if there was any. Old Wu carefully verified it, but stood up and sighed: "College students are good, they are studying machinery?"

"No, I've seen it a little." Su Cheng smiled. He went to find a job after the internship, and then traveled to this era, holding a wrench, and feeling quite familiar.

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

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

"The college student will repair the machine. The base was loose just now, and he saw it." Old Wu's apprentice was only 17 years old and lively. He was eager to see something happen every day, so he could not hold on now.

Dou Wanshan couldn't help but look at Lao Wu.

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

"When the machine is parked, you can see that the base is loose?" The old workers present heard the key.

Su Cheng smiled honestly and said, "I happened to be comparing the line, and I found that it was biased, so I straightened it out."

"How did you think of it as a slicker?"

"I see you all went down the well, so I wandered around the kowtow machine, I was idle." Su Cheng said in a word. He checked the bullet line as a subconscious behavior, but the cultivation of this behavior has been systematically cultivated and educated.

In serious oil production machinery maintenance tutorials, ancient products such as beam oil pumps have long been studied and broken. Any problem with any part has corresponding inspection items. For example, if the pump is vibrating, the impact load, coupling screws, chassis or foundation should be checked. In 1987, some state-owned enterprises may have such research results, but they are mostly used in their own small circles. In terms of the grassroots line, it depends on the master's experience and judgment.

Su Cheng didn't know if there was a systematic maintenance manual now, so he used an excuse instead.

Old Wu shook his head with emotion and said, "I have been in the well station for 20 years, and I didn't think about going to see the bullet line just now."

"Is Xiao Su a college student?" Dou Wanshan wiped his face and went downstairs again.

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

As he spoke, he opened the oil tank of the gearbox and removed the inside.

In the huge box, lubricating oil and crude oil were mixed together, and there were vaguely rag heads, sand and bricks underneath.

"How could there be bricks?" Su Cheng was immediately messy.

"This is not enough oily surface. Throwing something in can increase the liquid level. Last time Xiao Hei happened to pick up two bricks..." Lao Wu said very naturally.

Su Cheng widened his eyes: "You lost it?"

"This is nothing."

"What's wrong with the rag head and crude oil there?" Su Cheng took a stick and stirred it in the gearbox for a few times. Otherwise, the beam-type oil pump is easy to maintain, the gears work in this environment, and have been working for more than ten years. Good oil bath lubrication has become a Gobi bath.

Old Wu's apprentice Xiao Hei laughed and said, "I also received it."

“To increase the liquid level?”

"I'm afraid of stealing." Xiao Hei said it very simply.

In the 1980s, the time when oil rats just began to appear but were the most rampant. The entire Bohai Bay was filled with local oil rats and oil mice from other places. Lubricating oil is a very expensive thing. If sold in the store, one pound of lubricating oil can be as high as two pounds of vegetable oil. There are tens of thousands of oil production machines in the oil field, and it is not difficult for people to steal it. If the lubricating oil is mixed with crude oil, it will not be sold for price. Although the reducer will suffer from certain wear, it is much smaller than the wear caused by the stolen oil.

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

"No wear or breakage, no tooth surface pitting or peeling..." Xiao Hei said with a strange "hmm" and said, "It's weird, the gears are fine, why can't the gearbox work?"

Su Cheng recalled the knowledge he had learned, but focused his attention on the axis.

Old Wu kept paying attention to him, and at this moment, he smiled and said, "Xiao Su, tell me."

"It's time to connect the shaft. Since there are no broken teeth, it should be that the driven wheel of the intermediate shaft and the fasteners of the shaft are loose." Su Cheng did not make any actual measurements, but judged completely based on book knowledge.

Xiao Hei immediately went to check it out, and found the loosened part. He couldn't help but be surprised and said, "How did you know."

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

In fact, they are not good at improving their skills, but rather good at standard procedures.

Mature products should have mature maintenance guidelines, analyze all possibilities based on appearances, and then exclude and screen. However, China did not pursue single-person efficiency during this period, nor did it have the energy to focus on employee training. Masters and apprentices can often lead to high-level and insightful senior workers, but the time will be delayed for quite a long time.

Lao Wu, regardless of where Su Cheng learned the skills, slapped his hand with the oil on his shoulder, and smiled and shouted, "Our team made a profit, a big job."
