Chapter 175 The Factory Director’s Little Plan (Fourth Update)

"How long is this one?" the factory director asked, looking at the woven steel wire mesh cover.

"The current design is 200 meters." Liu Hai has no choice. It is technically difficult to build a one-time molding production line. This is the production model of Batie's small workshop.

High-pressure explosion-proof pipes are covered with several layers of mesh sleeves, and several sets of mesh sleeves of different specifications are installed on the equipment. For example, if 200 meters of explosion-proof pipes are produced at one time, how many raw materials are added at one time to produce 200 meters, and then prepare for the second production.

This kind of small-scale production is suitable for today's big environment. The integrated automatic production line has high demand for electricity, raw material security, etc. If the voltage is accidentally unstable, the mold temperature may not be reached and it will be scrapped. .

This can produce 200 meters at a time. Even if there is a power outage or the machine is damaged, not much material will be wasted.

Of course in total comparison. This kind of material wastes a lot of money. If it is produced in an integrated manner, as long as the production is stable, there will be no problem.

"Tsk, ok, ok." Sun Aiguo was very satisfied. Now the motorcycle factory is ready to hand over all motorcycle parts production to other factories, but other factories are not ready yet.

"Don't be too tired, don't be in a hurry." Sun Aiguo looked at his bangs again, becoming more and more satisfied with them.

"Director, let's take a rest together when this is finished." Liu Hai planned to work overtime and finish this, then go back to the village to tell the village about the cabbage and take a look at his home.

"Just tell me if you need anything." Sun Aiguo patted Liu Hai's shoulder again.

The factory director left, preparing to go to the construction department to build the factory building quickly, no matter what. The technology for high-pressure explosion-proof pipes should be developed soon. By the time the technology is available, there will be no room.

After the research and development of the net sleeve machine is completed, the next step is the production of high-pressure pipes, mainly the temperature of the nozzle mold, for which there are already rubber test data.

This design is simple, mainly for the subsequent debugging work. The process is probably that the feed port enters the nozzle mold at a certain temperature to form a pipe with a certain thickness.

When the first water outlet comes out, immediately cover it with the first layer of net cover, then cover it with layers of rubber, and then cover it with the second layer of net cover. The gaps in this net cover cannot be too dense. If it is too dense, the rubber cannot be combined.

The key is this temperature and the speed at which the nozzle mold comes out, so that several layers of coating can be integrated with the rubber tube.

Several layers of netting must be completed on the nozzle mold of Jimi Factory. It takes less than ten seconds from the feed port to the discharge port. The nozzle temperature is related to the discharge speed.

If the material is discharged quickly, the temperature will definitely be low. If the material is discharged slowly, the temperature will be high and it will be easily deformed. Just like a hot-melt water pipe, you must ensure that the outer layer melts and the inner layer does not deform...

The mesh sleeve production equipment can adjust the diameter of the mesh sleeve to adapt to high-pressure explosion-proof pipes of different diameters.

When Liu Hai got tired of drawing in the office, he came out to look at his sweet potatoes and potatoes. I don’t know if it’s the wasteland or the seeds, or maybe it’s the burned soil. Each of the soil bags has begun to crack. This is the following. There are sweet potatoes.

Liu Hai has been plowing sweet potato vines recently, and even drying sweet potato stalks when he has nothing to do. This stuff is delicious, modern export peninsula, small book.

Even after drying, Liu Hai and others didn't take it home. After all, the land was collectively owned and they were left here to be handed over later.

"Section Chief, these sweet potatoes are growing a lot. If you look at the cracked mud, you can see the sweet potatoes." Li Dali and others also learned to farm, pointing to the cracked soil and said.

"Well, maybe it's because of this wasteland?" Liu Hai wasn't sure. Crops must have stable traits. This thing is only in its second year. Who knows whether it will be stable or unstable in the future.

Li Dali just said that. Li Dali didn't know anything about agriculture.

Liu Hai will wait until harvest time to talk about it. The teacher has a classmate who is engaged in agriculture. He asked his classmate to come and take a look. If it really doesn't work, he will promote it in the village next year.

In the next three years, natural causes accounted for part of the factor, and there were also people...

However, as new sources of income have been opened up on Hong Kong Island, they may not be so embarrassed.

He was so busy that Liu Hai didn't even return to the courtyard once. Seeing that the equipment was gradually being completed, when Liu Hai went to Teacher Zhu's class on Sunday, he said hello to Sun Desheng and said that he would buy some meat or something in a few days.

Wang Hongmei was at home, and Liu Hai couldn't give her anything else, but she could still bring some meat when she went back. After all, the baby was hers, and she didn't lack this.

The 250 motorcycle was still known to Petrov and others, so Liu Hai just let them ride it.

In the laboratory building, the high-pressure pipe equipment has been manufactured and is being debugged.

"Li Dali, slow down." There was a pungent smell inside the factory. Liu Hai was wearing a dust mask, mainly because the gas mask was inconvenient to wear.

Li Dali and others also wore dust masks, while Sun Aiguo and others looked like no one else at all and instead looked closer.

Li Dali lowered the speed of the nozzle by one gear. Liu Hai watched the rubber particles being continuously transported in. There was a rubber pipe coming out of the nozzle. The speed of the rubber pipe at the nozzle automatically took away the first layer of net cover, and a net cover was placed on it. Pressure device to prevent the net sleeve from shrinking into a ball.

Originally, 200 meters of pipe were produced at a time, but after debugging the machine, the production was only 50 centimeters.

Sun Aiguo and others looked at the cut products, including the four layers of steel mesh in the middle of the rubber pipe and the explosion-proof high-pressure pipe. The main technical problem lies in the rubber pipe. The accessories at both ends are not technically difficult.

"That's good."

"Well, every time we produce, some materials are wasted." Liu Hai nodded.

Li Dali and the others shut down the machine, cleaned the nozzle, and then replaced the mesh cover to prepare for the second production. Of course, some waste materials can be recycled.

This kind of workshop-like equipment is not good at all. Of course, with this equipment, it can be handed over to other experts to optimize the combination and form an integrated production line.

An hour later, the second 200-meter high-pressure explosion-proof pipe from the factory was 180 meters qualified. Then the required length of explosion-proof hose was cut off and the metal fittings were installed.

"With this, can our 500-ton hydraulic press be mass-produced?" Sun Aiguo looked at the pipe and asked.

"It's possible, but some parts must be forged or die-cast, otherwise the service life will be reduced."

"It's nothing. Even if it only has one-third of the service life of the imported ones, it's fine. Imported ones are so expensive."

"It must be more than that."

"Um."

"You guys have to work harder here to produce different types of high-pressure explosion-proof pipes, and then I'll go to the ministry to check and accept them." Sun Aiguo can't wait to report. If your big brother doesn't sell it to us, then we have it too.

"Sure." Liu Hai nodded, but later in the production, Liu Hai started talking on his own, because the factory director transferred a dozen people from other workshops to learn the technology.

Sun Aiguo reported this time that he planned to ask the leaders for talents, lesbians with some education, preferably young ones. Although Comrade Liu Hai is not old enough to get married, it would be nice to arrange to work together first to get acquainted. ?
