Xue Xiaoman, as a ceramic equipment sales engineer in the idle equipment dispensing market, had been exposed to a large number of advanced ceramic machinery and equipment when he worked in eastern Guangdong before, and his knowledge was naturally higher than Zhong Zhuming.

Hearing Zhong Zhuming ask her, he said with a smile: "Mr. Zhong, you are really a fan of the authorities, if you want to verify whether Manager Guo's words are right, it is actually very simple, disassemble the cylinder of the filter press and inspect it on site?" ”

"yes, I'm really a fan of the authorities!"

Zhong Zhuming couldn't help but smile dumbly, and said: "Practice is the only criterion for testing the truth, Manager Guo's hand-touched inspection method is not accurate, open the oil cylinder to verify it on the spot, and you can draw conclusions!" ”

Speaking of this, he beckoned the minister of the equipment department to come over and asked him to send someone to open the cylinder of the filter press on the spot.

When the Hong Kong supplier installed and debugged this second-hand filter press, the equipment department of Crown Ceramics Company also sent engineers and maintenance engineers to participate in the whole process and received a one-week short-term technical training. Although it is a bit difficult to ask them to diagnose the cause of the failure of the equipment, it is still no problem to simply disassemble and maintain the equipment according to the drawings.

So the head of the equipment department sent out the three engineers who performed the best in the training, and with the cooperation of the three of them, they quickly disassembled the cylinder of the oil pump motor of the filter press, and then opened the cylinder on the spot for inspection.

As a result, as Guo Yonghe judged, the sealing ring on the piston of the cylinder was severely overworn, and it was obvious that it could no longer be used.

Looking at the piston seal of the oil cylinder that had been worn out and deformed in the hands of the maintenance engineer, there was a sudden sound of exclamation at the scene, especially Xue Xiaoman, whose eyes were extremely bright when he looked at Guo Yonghe.

Facts have proved that Guo Yonghe really did not say much, and his maintenance level far exceeded that of those foreign experts from Western ceramic powers that Xue Xiaoman had seen when he was in eastern Guangdong.

No matter how powerful the foreign experts of those ceramic powers are, the level is not as high as Guo Yonghe, and with a casual touch of his fingers, he can find the level of the root cause of the equipment, right?

Looking at the almost adoring gazes around him, Guo Yonghe did not have the slightest fluttering emotion.

You know, he was the chief technician of the new energy vehicle giant in his last life, and he also maintained the second-hand equipment of the same model for four or five years, in this case, let him come to diagnose the fault of the old-fashioned imported automatic filter press in the eighties, the difficulty is similar to the champion of the Chinese Table Tennis Super League to go to Western Europe to participate in the community table tennis friendly match, even if it is to chop melons and vegetables to win the championship, in the end it is boring, and there will be no sense of achievement.

"Mr. Cui, Mr. Zhong, and Xue Gong, you are happy slowly!"

Guo Yonghe said to Cui Yongjun, Zhong Zhuming and Xue Xiaoman, who were obviously in a state of excitement:

"Although the on-site inspection proved that there was indeed a problem with the piston seal of the cylinder, I would like to say that now is not the time for us to be happy. Because we can't tell at this time whether there are any faults in other parts of this automatic filter press.

"Because in many cases, when mechanical equipment fails, it may be caused by a single factor, or it may be caused by a combination of multiple factors.

"The current inspection results can only prove that there is indeed a problem with the oil seal piston seal ring of the oil pump motor, but we cannot rule out whether there is a problem with other parts of this equipment."

Hearing Guo Yonghe say this, Cui Yongjun, Zhong Zhuming, Xue Xiaoman, as well as the technical department and equipment department of Crown Ceramics Company, the people present suddenly calmed down.

Guo Yongjun is right, there are many times, the failure of mechanical equipment is not caused by a single reason, so even if one of the reasons is found, it may not be able to completely solve the failure of the equipment.

However, it is not difficult to verify this problem, as long as you go to the spare parts warehouse of the equipment department, find a spare oil pump motor oil seal piston seal ring to replace the worn piston seal, and then install the oil cylinder back, open the filter press to run on site, if there is no longer a problem of running the pulp, it means that the equipment running pulp is only a single fault of the piston sealing ring.

If there is still a phenomenon of running out of pulp, then you need to continue to investigate!

Soon, the maintenance engineer of the equipment department took a new piston sealing ring from the spare parts warehouse and installed it on the piston, and then added hydraulic oil to the cylinder, and then pushed the piston to move according to the operating scale on the manual, and used the pressure inside the cylinder to rise to the highest point to keep the piston tight.

In this case, another maintenance engineer took out a tool and disassembled the oil return pipe connection of the oil cylinder, and saw that there was no hydraulic oil seeping out inside, which indicated that there was no problem with the newly replaced piston sealing ring, and the sealing of the oil cylinder had been restored to the best state.

Immediately, the three maintenance engineers of the equipment department worked together to install the oil cylinder back into the oil pump motor, and asked Guo Yonghe and Xue Xiaoman to check it on site, and after confirming that there was no problem, they pressed the equipment switch to conduct an on-site start-up test.

With a roar, the automatic filter press slowly started running, and the speed became faster and faster.

Zhong Zhuming, Xue Xiaoman, and Cui Yongjun all stepped forward, gathered in front of the equipment, and stared closely at the place where the equipment originally ran the slurry, but the machine ran for more than an hour, and the joints of the shell were still completely dry, and there were no traces of water and mud seeping out.

In this process, Guo Yonghe did not look at the original place where the pulp was running, but kept pacing in circles around eagerly, listening to the sound of the equipment running for abnormalities, and at the same time observing whether the power parts of the equipment were crawling, vibrating and other abnormal conditions.

Luckily, none of these cases are any.

Seeing that more than an hour had passed, and there was no more running pulp in the place where the original pulp was run, Guo Yonghe nodded at Zhong Zhuming and said:

"Mr. Zhong, okay, no problem, it shows that the problem of the equipment running out of slurry before is indeed caused by the oil seal piston seal ring of the oil pump motor, you can rest assured now!"

Zhong Zhuming also breathed a sigh of relief.

Before, the equipment began to run out of pulp after two or three minutes, but now the equipment has been running for more than an hour, and there has been no running of pulp, indicating that this fault has really been solved.

"Manager Guo, thank you so much!"

He went up and grabbed Guo Yonghe's hand, shaking it violently, and said: "How much is the maintenance fee this time, you name the number, I will immediately ask someone from the finance department to write a check!" ”
