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

Su Cheng straightened his waist and said with an innocent expression: "I see that the screws on the base are loose, tighten it." ”

"The screws of the base, there is a head. Lao Wu was too nervous just now, and after coming over, his tone calmed down a bit, and said: "You are too tight, the donkey's head is up and down, after a long time, you can't shake other screws loose? ”

As he spoke, he pulled out the wrench from his waist, stepped forward and put it on the screw, twisting and loosening, but it was a "huh".

A mechanic like him, who has 20 years of experience, can tell the eighth chapter: The maintenance worker knows whether the screws are loose or tighter when he moves, which is more effective than any test equipment. Tens of thousands of oil production units in Shengli Oilfield, thousands of inspection tasks every week, and hundreds of maintenance tasks are all built by such senior workers with their hands.

What made Lao Wu strange was that he obviously saw Su Cheng screwing, but when he started by himself, the tightness of the screws was just right. So as soon as he tightened it, he relaxed again.

As soon as the expert made a move, he knew if there was one, Lao Wu carefully verified it again, stood up and sighed: "College students are good, learn mechanics?"

"No, I've seen a little. Su Cheng smiled. He went to look for a job after his internship, and then he traveled to this era, pinching the wrench, and there was a sense of familiarity.

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

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

"The college student will repair the machine, and the base was loose just now, and he saw it. "Lao Wu's apprentice is only 17 years old, and he has a lively temperament, and he looks forward to something every day, and now he can't live with it.

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

The latter nodded and said, "I saw him go around in a circle, and he took the wrench to Chapter 8: Maintenance Screw, and then he roared." ”

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

Su Cheng smiled honestly: "I just compared the bullet line, and found that there was a deviation, so I corrected it." ”

"How did you come up with the idea of a bullet line?"

"I saw that you all went down the well, so I walked around the kowtow machine for a while, idle. Sioux City said in a word. It is indeed a subconscious behavior for him to check the elastic line, but the cultivation of this behavior has been systematically cultivated and educated.

In the serious oil production machinery maintenance tutorial, such ancient products as beam pumping units have long been studied. If there is a problem in any part, there are corresponding inspection items, such as pumping unit vibration, the shock load should be checked, and the connecting screws, chassis or foundation are suspended. In 1987, some state-owned enterprises may have such research results, but most of them are used in their own small circles, and the specific grassroots frontline depends on the experience and judgment of the master after all.

Sioux City also didn't know if there was a systematic maintenance manual now, so he replaced it with a pretext.

Lao Wu shook his head with emotion and said, "I've been in the well station for 20 years, and I didn't think about going 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, let's go and check the gearbox together." ”

As he spoke, he lifted the oil groove of the gearbox and removed the inside.

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

"How can there be bricks?" Sioux City was messy.

"This is not enough oil level, throw something into it, it can raise the liquid level, last time Xiao Hei just picked up two bricks...... "Lao Wu said very naturally.

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

"That's not nonsense. ”

"What's the matter with the rag head and the crude oil in there?" Su Cheng took a stick and stirred it twice in the reducer, not to mention that the beam pumping unit is easy to maintain, the gear works in this environment, and it has been working for more than ten years, and a good oil bath lubrication has become a Gobi bath.

Lao Wu's apprentice Xiao Hei laughed twice and said, "I also poured it." ”

"To raise the level?"

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

The 80s were the time when gas guzzlers were just beginning to appear, but they were the most rampant. The entire Bohai Bay is full of local oil guzzlers and foreign oil rats. Lubricating oil is a very expensive thing, if it is sold in a store, one pound of lubricating oil is worth two pounds of vegetable oil. There are tens of thousands of oil extractors in the oil field, and it is not difficult for people to steal them. Lubricating oil mixed with crude oil, it will not be sold for a price, although the reducer will suffer a certain amount of wear and tear, but it is much smaller than the wear caused by oil theft.

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

"There is no wear and fracture, and there is no tooth surface pitting and spalling...... "Hmm" the little black monster said, "This is strange, the gear is fine, why can't the reducer turn." ”

Su Cheng recalled what he had learned, but kept his eyes on the axis.

Lao Wu had been paying attention to him, and at this time, a smile appeared on the corner of his mouth, and he said, "Xiao Su, you can talk about it." ”

"Let's string it. Since there is no broken tooth, it should be that the driven wheel of the intermediate shaft and the fasteners of the shaft are loose. "Sioux City didn't actually measure, but judged it entirely based on book knowledge.

Xiao Hei immediately went to check, and sure enough, he found the loose parts, and couldn't help but be surprised: "How do you know." ”

Sioux City shrugged, not knowing how to explain it. This kind of repair method is actually very common, for example, the network engineer of the telecom, can guide the user to solve the problem on the phone. Zoom in to factory equipment, and a single video conference can save several airfares.

It's not that they're skilled, it's that the standard procedures are good.

Mature products should have mature maintenance guidelines, analyze all possibilities according to appearances, and then carry out exclusion screening. However, during this period, China did not pursue individual efficiency, nor did it have the energy to devote time to staff training. The master and the apprentice can often bring out a very high level of understanding of the senior worker, but the time will drag on for a long time.

Lao Wu Cai didn't care where Su Cheng learned the technique, his hand mixed with engine oil, patted him on the shoulder, and shouted with a smile: "Our team has earned, and there is a big job." ”
