After signing the purchase contract with Hao Guoqing on behalf of Tianyang Ceramics Factory, Lv Collective declined the invitation to Hao Guoqing's dinner, and took the driver and Hao Shuang to the staff canteen of Xiangyangpo Clay Mine to eat a bowl of mutton stewed noodles, and immediately set off to Tianyang.

Although Tianbei and Tianyang are only more than 80 kilometers apart, but because the highway between the two cities is a large channel for the export of Shanxi coal, and there are two obstacles in the middle of the Beijing-Guangzhou Railway and the Yellow River, there are often large traffic jams, so although they set off at six o'clock in the afternoon, they rushed to the Tianyang Ceramics Factory, it was already eleven o'clock in the evening.

So Lu Collective settled Hao Shuang in the guest house of the ceramic factory, let him rest well, and after recuperating his spirits, he went to the factory the next morning to check the fault of the hydraulic filter press.

At seven o'clock the next morning, Lu Gonggong rushed to the guest house in person and accompanied Hao Shuang to breakfast.

After breakfast, Lu led Hao Shuang to the pulping workshop of the ceramic factory.

In the pulping workshop, Sun Guichao, deputy director and chief engineer in charge of production, is leading a group of technicians from the technical department and the equipment department to wait.

Seeing Lu Gong coming in, he hurriedly greeted him and asked, "Director Lu, didn't you say that you invited experts to come over, but what about others?"

"Old Sun, what kind of eyes do you have?" Director Lu glared at Sun Guichao dissatisfiedly, and stretched out his finger to point at Hao Shuang who was standing next to him, "Isn't this Expert Hao?

What? This is Expert Hao? Director Lu, didn't you say that Expert Hao is a college student who has not yet graduated? But this person in front of you, just by his appearance, you say that he is an associate professor of the university, I am afraid that some people will believe him.

"Ah, Expert Hao, hello, hello! I don't know Taishan, I'm rude, please forgive me!" Sun Guichao stretched out his hands to Hao Shuang and apologized again and again.

"Who is this?" Hao Shuang shook hands with Sun Guichao and looked at Lu Gongji.

"Expert Hao, this is Comrade Sun Guichao, our deputy director of production and chief engineer!" Lu Collective hurriedly introduced. Since last night, Lu Collective led Hao Shuang to the factory guest house to settle down, and his title for Hao Shuang has changed from "Little Hao" to "Hao Expert", no matter how Hao Shuang opposes, it is useless.

"Hello Chief Engineer Sun!" Hao Shuang simply said hello to Sun Guichao, and then without delay, he directly asked Lu Gonggong to take him to the front of the hydraulic filter press.

"Hehe," Hao Shuang just glanced at this hydraulic filter press, then laughed, and said to Lu Gongji and Sun Guichao: "Director Lu, Chief Engineer Sun, from the perspective of equipment appearance, this hydraulic filter press should be the 300/1200 plate-and-frame underflow diaphragm polypropylene filter plate automatic filter press of Nellie Company's eighty-three model. ”

Sun Guichao saw that Hao Shuang didn't even look at the equipment nameplate on the machine, so he accurately reported the accurate model of this hydraulic filter press, and couldn't help but take his eyes to look at Lu Gonggong.

"Old Sun, don't look at me!" Lu Gong spread his hands and said, "I only told Expert Hao yesterday that the model of the filter plate is one meter two by one meter two. ”

As an old buddy for many years, Sun Guichao certainly believes that Lu Gongcheng will not lie about such a trivial matter, and there is no need to lie.

In this way, this Hao Shuang really didn't brag, he was really an expert in imported hydraulic filter presses. As far as Sun Guichao knows, it is impossible to accurately report the model of the filter press verbatim just by looking at the model of a filter plate and the appearance of the equipment of the hydraulic filter press.

"Expert Hao, what you said is right, this filter press is indeed the 300/1200 plate-and-frame underflow diaphragm polypropylene filter plate automatic filter press of Nellie's eighty-three model!" Sun Guichao took Hao Shuang to the side of the machine and pointed to the equipment nameplate on it.

Hao Shuang confidently touched the hairline on his forehead that towered into the sky.

He spent a lot of effort on the hydraulic filter press of Neckie Company in his last life, and if he couldn't even recognize the model of an ordinary hydraulic filter press in Neckie's company, then wouldn't his hair in his previous life be gray?

"Director Lu," Hao Shuang pointed to the machine, "Turn the machine on and run, and I'll see the situation." ”

"Let's start it now, don't you read the equipment manual first?" Lu Gongji and Sun Guichao glanced at each other and said in surprise.

"No, no, such a simple machine, what kind of manual do you need to read?" Hao Shuang waved his hand disappretently, "Let's fight quickly, don't waste time!"

"Okay!" Seeing that Hao Shuang was so confident, Lu Gongji met Sun Guichao again, and then ordered the head of the equipment section to start the hydraulic filter press.

So the filter press was running in the constant roar.

"Director Lu, let everyone stop talking!"

After the filter press started, Hao Shuang put forward another request to Lu Collective.

All don't talk?

Do you say that you are afraid that other people's words will interfere with your train of thought?

Lu Zheng couldn't keep up with Hao Shuang's thinking rhythm, and didn't know what kind of plane he was going to build, but he still gave the order without hesitation, so that everyone present was not allowed to speak.

Seeing that everyone had closed their mouths, Hao Shuang first rotated around the filter press twice with his hands behind his back, and then observed the part where the filter press ran slurry for a few minutes, and then walked a few steps to the power part of the filter press, put his hands behind his back, closed his eyes, tilted his ears slightly, and stood there motionless.

Lu Gongcheng, Sun Guichao and a group of technicians looked at each other, not knowing what Hao Shuang was doing.

Lu Gongcheng wanted to step forward to ask, but he remembered Hao Shuang's explanation just now, and asked everyone not to speak, including him, the leader of Tianyang Ceramics Factory, so he forced himself to suppress the doubts in his heart and stood in place waiting for Hao Shuang.

At this time, the air in the entire scene seemed to be frozen, and the time seemed extraordinarily long, and everyone held their breath, waiting for Hao Shuang's next move.

Finally, Hao Shuang opened his eyes, smiled, and said to Lu Gongji: "Director Lu, you can speak now!"

Lu Gongji couldn't help but let out a long breath, he glanced down at his watch, obviously only more than five minutes had passed, how could he feel like more than five centuries had passed.

"Expert Hao, how is it, what have you gained?" Lu Gong hurriedly approached Hao Shuang's side and asked.

"Hehe," Hao Shuang laughed, pointed to the part of the oil pump motor of the hydraulic filter press, and said: "Judging from the sound of the machine running, it should be the failure of the electromagnetic reversing valve, which leads to the low pressure of the hydraulic oil when working, which causes the force generated by the cylinder piston to compress the filter cloth of each filter plate is small, resulting in the formation of a gap between the contact surfaces of each filter plate and the leakage of mud!"

What the?

Just by the sound of the machine, can you hear that the solenoid reversing valve is malfunctioning?

That's amazing, isn't it?

Including Lu Gonggong and Sun Guichao, everyone present was stunned and couldn't believe their ears!
