How long can the vacuum bellows be used for welding vacuum bellows? The use time of the vacuum bellows is determined by the number of times of use when the bellows is working. The less the use times, the shorter the use time of the bellows. The more times the bellows is used, the longer the use time of the bellows. High, the bellows plays a very important role in the instrument, so it is necessary to carefully observe the use time of the bellows, and when the use time is about to be used up, replace the new bellows to continue the operation of the instrument, and use the bellows If the method is not used, the use time of the bellows will also be somewhat affected. Some instruments require a long bellows and some need not be so long. Let us give an example. When the vacuum bellows is used in a constant temperature controller with a high switching frequency, its life must reach 10,000 times to meet the requirements. When the bellows is used as a vacuum switch as a vacuum seal, its life must reach 30,000 times to ensure normal operation. The two examples just now can show that the use time of the bellows is related to the place where it is used. The high-fitness has a strong usability, and the low-fitness has a low usage rate."
