Computer room precision air conditioning screw damage reason 【 Room air conditioning 】 1, the screw rotation inside the barrel, oil and compressed gases and screw and friction in the body, the work of the screw surface gradually wear: screw diameter reduced gradually, gradually increase the body's inner hole diameter. So, screw with the body's diameter clearance, with the gradual wear and tear of the a little bit more. But because of the body in front of the nose and the resistance of shunt board has not changed, this increases the squeezed forward gas leakage flow, namely the gas and oil from diameter clearance flow has increased in the direction of inlet. The results make discharge machine flow down. 2, if there is acid and other corrosive substances in gas, to speed up the screw and the body wear and tear. 3, machine wear and abrasive, or a metal foreign bodies with material, to rotate the screw torque force suddenly increases, the torque beyond the ultimate strength of the screw, the screw twist off. This is a kind of unconventional accident damage. Screw repair 【 Precision air conditioning 】 1, twist off the screw according to the actual diameter of the body, according to the gap with the body's normal deviation to the new outer diameter of the screw is made. 2, wear threads of the screw diameter to reduce the surface after treatment, thermal spraying alloy, and then via grinding to size. This approach generally have professional spraying plant, repairing cost is still relatively low. 3, in the wear of the screw thread part of surfacing welding alloy. According to screw the wear degree of surfacing welding 1 ~ 2 mm thick, then grinding screw to size. The wear resistant alloy by C, Cr, Vi, Co, W and B material composition and so on, to increase the screw's ability to resist wear and corrosion resistance. Professional welding plant to the processing fee is very high, in addition to the special requirements of the screw, rarely used. 4, to repair the screw can also be used surface hard chromium plating method, chromium is wear resistance and corrosion resistance of metal, but the hard chromium layer is easy to fall off. The body's repair 【 Room air conditioning 】 Within the body of the surface hardness is higher than the screw, it's more damage than the screw later. Scrapping is the inner diameter of the body due to time and wear. It repair method is as follows: 1, increase the diameter of the body due to wear and tear, if there is a certain of nitriding layer, can put the bore hole directly, in the grinding to a new diameter size, and then according to the diameter of the new screw. 2, the body diameter by machining renovation to casting alloy, thickness between 1 ~ 2 mm, then processed to size.
