Hardware is the key, and shock wave generator is the key, which determines the crushing energy and time, and even the accuracy at any time. Pure copper is the best material with high hardness, strong energy, short crushing time and clean crushing. At present, only Shanghai Jiaotong University and Dornier in Germany are using gravel. One of these two companies is a junior college graduate, and pays attention to technology, while the other is meticulous. In order to save costs, they all use stainless steel or other materials. After three months, the cylinder will be seriously worn.
From Shanghai No.1 Hospital to No.10 Hospital Huashan Hospital Ruijin Hospital Huadong Hospital, dozens of top-three hospitals and even internationally renowned hospitals, all of them are machines from Shanghai Jiaotong University and Dornier, Germany. I worked as an intern in East China Hospital, then worked in Zhongshan Hospital, and later transferred to Ruijin. Experience tells me that Dornier's equipment is the best, but the price is too expensive. As a listed company, the equipment is relatively strong and durable. Our hospital bought three sets, the earliest one was bought by Director Liu. It's been 15 years, and it still works. It's really stable, and the people at Jiaotong University are not very smooth. The traditional concept, equipment and hardware of the school are first-class, and the supporting X-ray machines are all developed and produced by ourselves. Compared with other domestic stone crusher enterprises,
By the way, the salesman of Jiaotong University is more sincere. Their electrodes can be used as three patients, and those of other enterprises can only be used as one patient, or even 2-3 electrodes can be used as one patient, but the price of electrodes is similar, which means that the salesman of Jiaotong University is kind in promotion. Only one electrode is like this. Think about the difference. . . ? Even the high-voltage generator of IMD in Italy used in Jiaotong University is extremely expensive, while other stone crusher enterprises I contacted are all made in China. What's worse, they are still using artificial frequency X-ray machines. The radiation dose is too high, so I can only say: some businessmen can sell poor products at high prices, some are academic, lack publicity about good things, or don't want to sell more money at all.
Really experience, please decide for yourself.
