Weichai: Scrapped engine “really” is back to life

As the heart of a motor vehicle, the engine can only be used once in the eyes of most people, but with the development of the remanufacturing industry in our country, after the used engine is processed by technology, it can be used as a new engine. On October 31, the reporter went to Weichai Power (Weifang) Remanufacturing Co., Ltd. and witnessed the process of rejuvenating the entire used engine.

Handling and disassembling depends entirely on the robot

The reporter, led by Yu Qiang, manager of the Integrated Management Office of Weichai Power (Weifang) Remanufacturing Co., Ltd., first came to the dismantling plant of the engine and saw hundreds of waste engines shipped from across the country. The top of the engine is covered with a layer of putty. Some bodies or parts have been damaged. How are these engines handled?

In the dismantling workshop, there is a row of engines being dismantled. The workers first use robots to dismantle the lines and parts on the surface of the engine one by one. The second step is to dismantle the body. Since the engine is a precision instrument, each engine has at least tens of thousands of components. Many parts and components reporters saw it for the first time. Some parts that had only palms were more than 20 kilograms in weight. "Each engine has 850 kilograms of weight, and it is certainly impossible for manpower to move!" Yu Qiang told reporters that in the process of engine handling and dismantling, it is operated by machinery. Workers only need to be responsible for technical issues.

After dismantling, the next step is cleaning. Cleaning is not a general sense of cleaning. Instead of water, a few micrometers of sand are used for physical cleaning, so that the washed out components are no different from the new components.

120 decibels under the "trial test"

Subsequently, the reporter went to the body processing area, where a row of engines is placed, at first glance, the appearance and the new engine is no different.

Yu Qiang told reporters that discarded parts and components on used engines have been completely processed within the process of entering the machine body. The replacement process, the processing of the treatment, all the new circuit replacement, only the body casing, gears are reserved. And other parts. Each engine has reached the level of the new engine. "This time the engine can not be shipped from the factory, must be tested before leaving the factory!" Yu Qiang said.

The reporter followed Yu Qiang and came to the testing workshop. Just after he entered the workshop entrance, there was a roaring engine roar inside, and it was not long before the ears buzzed. The reporter noticed on the scene that there were operators in front of each engine to continuously check the operation of the engine. “The sound emitted by the engine during operation can reach 120 decibels, which is unbearable to the average person, but the workers have special ear plugs in their ears. Even at such high decibels, the impact on them is very small. The engine comes out of the test-vehicle workshop. After that, basically the power of the new engine can be achieved. After painting and packaging, it can be sold directly to the market,” said Yu Qiang.

Remanufacturing is not ordinary

Remanufacturing technology is not like refurbishing technology, facing such doubts. Yu Qiang told reporters that remanufacturing technology is not an ordinary renovation. The old engine was completely dismantled in the remanufacturing process. All parts were sorted and measured. However, the ordinary refurbishment or overhaul technology only disassembled the old engine failure site, and the hidden quality problem could not be ruled out. In the process of cleaning components, it is also different from ordinary refurbishment or overhaul technologies. They use special equipment to clean and inspect all parts and components, rework or replace failed parts, and engine overhaul only replaces worn and defective parts.

In addition, remanufactured engines not only ensure the quality of the engine, but also ensure the performance of the engine. The device for remanufacturing the product is a process of fully restoring the quality of the new product, as well as the product quality and service guarantee of the new product. These technologies and capabilities cannot be achieved with ordinary refurbishment or overhaul technologies. "After the remanufactured waste engine is processed, the quality is the same as that of the new machine. The warranty period is the same as the new machine." Yu Qiang's voice is full of pride.

Price discount and special mark

Speaking of the engine after remanufacturing, Chen Gang, who works in the engineering vehicle industry in Kuiwen District, has a deep understanding. He told reporters that six years ago, he and his friends bought two large excavators. Three years later, the engine started to have minor problems. Although it was overhauled once a year, these minor problems could not be solved. Lost one. This spring, he heard that Weichai did not hesitate to buy one after remanufacturing the engine. "To put on a new engine, the remaining excavator will be the same as the new one. There will be no problem in five years. Buying a new engine will cost less than 40,000 yuan, eliminating the need for overhaul fees of 10,000 yuan a year and replacing new ones. The engine is very suitable." Chen Gang said.

Yu Qiang told reporters that the engines handled by the company are now collected from Weichai power distribution centers across the country. The price of the new engine that has been processed is only 75% of the new aircraft price, and they are all marked with the English alphabet “R”. "," represents the engine that is processed by remanufacturing technology.
