Xiao Liu was carrying the gifts.
There was fruit, malt extract, cigarettes, and alcohol.
Wiping the sweat from his brow, he kept greeting Wu Changfeng.
Wu Changfeng had a strange look on his face.
How did this thing end up here?
After receiving the gift, Wu Changfeng invited Xiao Liu to his office.
He asked, "Aren't you conducting industrial experiments at the Cangxi Iron Mine? Do you have time to visit me?"
"Won't they just happen to be passing by?"
Xiao Liu smiled wryly: "Brother Wu, I would be happy if you were just passing by. I came here specifically to find you."
"Looking for me?" Wu Changfeng asked warily, "Is Mine Manager Ren up to his old tricks again?"
"No, no, I can't, I won't." Xiao Liu quickly denied it three times in a row: "Manager Ren has been very considerate of our Chenshui Heavy Machinery Plant. Of course, it's all because of Brother Wu."
"Then why did you come all the way to see me? I've already paved the way for you."
After hesitating for a long time, Xiao Liu said, "There's another situation."
"Is there something else going on?"
Wu Changfeng is suspicious.
In what situations do you absolutely need to contact me?
I don't understand your heavy industry stuff either.
Will I not be influenced by Minister Tang's style?
When in doubt, consult Changfeng?
Oh my god!
Am I a firefighter?
Just then.
The phone rang.
I can't help but think of it, because Minister Tang called!
After a short while, the connection was established.
Minister Xu from the Equipment Division called again.
It took a few minutes.
Director Xue, who had been submerged, called again.
Then I received a call from the factory manager of the submersible heavy machinery factory.
That was until the call from Manager Ren of Cangxi Iron Mine ended.
That finally stopped the phone calls.
They were talking about the same thing.
That was also the purpose of Xiao Liu's visit.
Wu Changfeng slumped onto the sofa, rubbing his temples, and said, "Tell me about the situation again."
Xiao Liu nodded: "That's right."
Xiao Liu took a smooth iron rod out of his backpack.
The top is machined into grooves by a lathe.
"Is this on a hydraulic valve?"
Wu Changfeng recognized him at a glance.
This is the valve core in a hydraulic valve.
The valve core moves relative to the valve core within the hydraulic valve to control pressure, flow rate, and direction.
It can be said to be the core component of a hydraulic valve.
Extremely precise and precious.
It is very common in mechanical applications.
It can be said that hydraulics and electricity form the backbone of the world's industry.
Xiao Liu nodded: "Indeed, this is a valve core, a component used in the tipper of heavy transport vehicles to provide powerful power to the truck bed."
"Look here."
Xiao Liu pointed to one end of the valve core, which was as smooth as a mirror.
There is a small black dot and a scratch here.
Xiao Liu continued, "These scratches weren't caused during the process of bringing it here, but rather from wear and tear on the valve block during use."
"So there's an oil leak?" Wu Changfeng asked.
This situation is absolutely unacceptable in heavy equipment.
This will seriously jeopardize the normal operation of the equipment.
It can support a hundred tons of iron ore, but you're leaking oil and the pressure is leaking out.
Who will get the shovels to unload the truck?
Xiao Liu nodded and said, "Not only is it leaking oil, but it also can't withstand the pressure, which makes it impossible for the truck bed to unload itself."
"Then you can replace it."
"This is the 10th valve core that has been replaced..."
Upon hearing this...
Wu Changfeng understood.
If the same part fails 10 times in a row, it's a hydraulic oil problem.
However, there are issues with product quality.
In hydraulic systems, there are two factors that affect operation: oil leakage and impurities in the hydraulic oil, such as emulsification or the presence of stones or debris.
This can lead to damage to hydraulic working components.
Looking at it this way...
If the same part fails repeatedly, it indicates a quality problem with the valve assembly.
"So?" Wu Changfeng asked tentatively.
If there are quality issues, you should contact the manufacturer.
Although Wu Changfeng already knew Xiao Liu's purpose, and several people had already asked Wu Changfeng to do things for them in the previous phone calls.
But Wu Changfeng thought this matter would be difficult to handle.
If Xiao Liu could decline, I wouldn't have to add any trouble for myself, right?
But Xiao Liu said:
"Brother Wu, I'm really out of ideas this time."
"You also said in the smelting department that localization is an inevitable path, and it is something we should support."
"This valve assembly is a product manufactured by Chicheng Hydraulic Factory."
“We have communicated with them countless times, repeatedly emphasizing that the quality is poor and is delaying our industrial experiments.”
"And the other party's attitude was one of the same thing: if the valve core is faulty, we will replace it for free."
Xiao Liu angrily retorted, "Is this some kind of free replacement issue? This is a product quality problem! We should find the cause at the source!"
"Just this one part has caused so much trouble!"
"It would result in the complete failure of industrial experiments."
Xiao Liu said with great distress: "Brother Wu, you may not know how much money the country has invested in the research and development of our domestically produced 150 heavy transport vehicle."
"If we fail because of this, tens of millions of dollars in research and development costs will be lost!"
"It's not that we can't shoulder the responsibility, but that we're letting down the task entrusted to us by the country, and the trust the country placed in our Chenshui Heavy Machinery Plant!"
"How can we explain this to the country?"
"Therefore, I would like to ask Brother Wu to step in and manage the hydraulic factory in Chicheng!"
"Make them improve the quality of the valve assembly."
"Only in this way can we avoid letting the country down."
Wu Changfeng kept his eyes closed and remained silent.
Xiao Liu's purpose was the same as that of Minister Xu, Minister Tang, and others.
