A common problem of QGB cylinder

What are the aspects QGB cylinder, general? Know these, for using QGB cylinder, there is a certain benefits, can accomplish know fairly well, also can know about QGB cylinder, more in-depth and comprehensive, so as to better use the element device QGB cylinder. 。 General QGB cylinder is cast, and aging treatment, after the factory will go to eliminate internal stress produced by casting. But if the time is too short, QGB cylinders in use process in the future they may also appear deformation phenomenon. 。 QGB force of the cylinder is very complex, in addition to the weight of the parts, such as static load, but also bear some other forces, including reaction, etc. , so in under the joint action of the force, deformation and leakage. 。 If QGB cylinder by load, the increase or decrease speed too fast, and if the temperature change is big, no warming cylinder right down or is not correct, will make problems QGB cylinder. 。 QGB cylinder produced stress after welding, but not to temper the QGB cylinder, to eliminate the stress, makes QGB cylinder there is a big residual stress, then in use process will appear to be out of shape. 。 QGB cylinder installation or maintenance, if some technical reasons, between the expansion of the makes it is not appropriate, then later QGB cylinder will be out of shape. 。 Sealant QGB cylinder quality is bad, or impurities, such as too much will make the sealing surface sealing performance is bad, make QGB cylinder problems. 。 Bolts and other fasteners installation is not correct, or substandard, etc. , will make the stress changes, or the formation of gap, will eventually make QGB cylinder leakage phenomenon.
