So under the command of Sun Guichao, the two masters with the best equipment technology in Tianyang Ceramics Factory cooperated with each other and quickly disassembled the oil cylinder of the filter press. Then they opened the oil cylinder on site for inspection. Sure enough, the seal on the piston had appeared.

It was severely worn and obviously no longer usable.

Looking at the badly worn sealing ring on Sun Guichao's hand, there was a burst of exclamation at the scene.

Expert Hao’s level is really too high, even higher than his hairline!

Isn't it an exaggeration to say that you can find out the root cause of this West German equipment with just a touch of your fingers?

As the center of everyone's admiration, Hao Shuang didn't feel arrogant at all.

For him, a technical expert in the ceramics industry in the 21st century, diagnosing the faults of an old-fashioned imported filter press from the 1980s is as difficult as asking an NBA superstar to fight a village.

There is no difference in the A-level basketball league.

If even this diagnosis is wrong, he might as well find a piece of tofu and kill him on the spot, instead of staying in the 1980s and embarrassing the 21st century time-traveling Japanese!

"Director Lu, Chief Engineer Sun," Hao Shuang said to the slightly excited Lu Group and Sun Guichao: "Although it has been proven that the sealing ring of the cylinder piston is indeed faulty, it is not the time to be happy yet. Because we cannot

Excluded, there is no problem with other parts of this hydraulic filter press."

After hearing what Hao Shuang said, Group Lu and Sun Guichao immediately calmed down.

This is indeed the case. Equipment failure is sometimes due to a single reason, and sometimes it is a mixture of multiple reasons. The current result can only be said to be that there is indeed a problem with the seal of the cylinder piston, but other parts of the equipment are.

If there is no problem, it cannot be ruled out.

Fortunately, this problem is not difficult to prove. You only need to go to the spare parts warehouse, replace it with a spare piston seal, then install the oil cylinder back and let the filter press run again on site, and you will be sure.

Soon, the technician took a brand new piston seal from the spare parts warehouse and replaced it, and then replenished the hydraulic oil in the tank. Then he pushed the piston according to the operating specifications to raise the cylinder pressure to the highest level, and the piston kept pressing.

In this case, when the oil return pipe joint is disassembled, no hydraulic oil flows out, indicating that the cylinder seal has been restored to its original state.

Immediately, the technicians installed the oil cylinder back into the filter press and started the test on site. The results showed that the working condition of the filter press was completely normal and there was no slurry leakage.

Hao Shuang walked around the filter press several times to make sure that there was nothing unusual about the sound of the machine's operation, and that there was no abnormality in the oil cylinder such as crawling or vibration.

Sun Guichao nodded.

After receiving Hao Shuang's final affirmation, the smiles on the faces of Lu Jihui and Sun Guichao bloomed again, "Expert Hao, so it means that the fault of the filter press has been completely solved? It will not run for a period of time, and the phenomenon of pulp leakage will occur again.

Bar?"

"So far, it seems so. At least I haven't found any other problems!" Hao Shuang said with a smile. "As for whether there will be problems with slurry running in the future, I can't guarantee. I can only say that as long as the filter press

If there is no problem with the filter plate and if the operating specifications are followed completely during use, the hydraulic device will not have any major problems for at least one or two years!"

"It doesn't take a year or two," Group Lu laughed with satisfaction and said, "As long as we can guarantee that there will be no problems before delivery at the end of June!"

Just as he said this, a young man hurried in from outside and reported to Lu Group: "Director Lu, a call from Xiangyangpo Clay Mine in Tianbei City came to your office, saying that they are looking for Expert Hao!"

oh?

Collective Lu and Hao Shuang looked at each other. It must be Hao Guoqing. Because before collective Lu took Hao Shuang away, he told Hao Guoqing that if he wanted to see Hao Shuang for anything, he would call Tianyang Ceramics Factory directly.

Just have an office.

But he didn't expect that just after one night, Hao Guoqing called, and he didn't know what the emergency was.

So Lu Jiji told Sun Guichao to stay in the workshop to observe the operating status of the filter press, while he hurried back to the factory director's office with Hao Shuang.

Hao Shuang grabbed the microphone on the table and called him first. After hearing Hao Guoqing's voice on the other side, he asked: "Dad, I'm here. Did something happen in the mine again?"

"In the mine? Nothing happened in the mine." Hao Guoqing laughed loudly on the phone, "With the wire transfer receipt from Director Lu, who dares to come out and show off?"

Wire transfer receipt?

Hao Shuang covered the microphone with his hand, turned around, and asked quietly to the group Lu next to him.

"Oh, that's it! I know that mine manager Hao's side is in a tight financial situation. I asked the Finance Department early this morning to wire the money for this month's clay purchase, and asked her to send the wire transfer receipt immediately after completing the procedures.

Fax it to mine manager Hao." Lu Jiji explained with a smile.

That’s so!

Lu Group is worthy of being the person in charge of a provincial second-level enterprise. He is open-minded in his work and every detail has been considered for him. He really can’t be considered a loss by following Lu Group on this trip to Tianyang City!

"Dad, since nothing happened at the mine, why did you call me?" Hao Shuang asked into the phone.

"Although nothing happened at the mine, something happened at Caifeng Ceramics Company!" Hao Guoqing said, "Your Uncle Liu just called me and told me that the sink body was poured from the production line of Caifeng Ceramics Company.

When I was preparing to send them to the kiln for firing today, I found that all the green bodies were cracked. Pan Jiahao from Taihu could not find out the cause. In the end, Wang Daojun from Caifeng Ceramics had to ask your Uncle Liu to call.

Ask when you can go over and help find out the reason."

Hao Shuang originally thought that it would take at least a day for the cracking problem of the body of Caifeng Ceramics Company to be revealed, but he did not expect that the debugging process there would progress so fast, and the cracking problem of the body was exposed this morning.

.

He couldn't help but sneered secretly.

Hum hum, let me help find the reason?

Go and have his spring and autumn dreams!

Lao Zhi hopes that the faults on Cai Feng’s ceramic production line will get bigger and bigger!

"Dad, I'm afraid I won't be able to go back in a short time!" Hao Shuang said with an embarrassed look on his face.

"Why? Is it because the equipment failure at Factory Director Lu's side is more difficult?" Hao Guoqing asked quickly.

"Yes!" Hao Shuang said, "Compared with the pouring production line of Neiqi Company at Caifeng Ceramics Company, this is my first time to come into contact with the hydraulic filter press at Tianyang Ceramics Factory. I have to learn everything from scratch, so the fault

It will be more difficult to investigate, and it will probably take less than ten days and a half to solve it!"

As Hao Shuang spoke, he secretly winked at Group Lu, telling him to pay attention to his cooperation and not to expose himself.

Lu Jiji nodded repeatedly to express his understanding.

Although he didn't understand why Hao Shuang lied to Hao Guoqing, considering that Hao Shuang had just helped him solve a big problem and saved nearly a million dollars in losses for Tianyang Ceramics Factory, he helped Hao Shuang

If you tell a little lie, what's the problem?

"Well, you can repair the equipment for Director Lu in Tianyang with peace of mind." Hao Guoqing had no doubt that the child he raised would lie to him, "I will tell you, Uncle Liu, let Hong Kong

Fang should figure out a solution first!"
Chapter completed!
