Seal installation and inspection brief description

The pressing cap on the seal should be made after the coupling is aligned. The bolt should be evenly supported to prevent the end face of the gland from being skewed. Check the points with a feeler gauge. The error is not more than 0.05 mm. Check the gland and shaft or shaft. The fit clearance of the outer diameter is the concentricity, and the circumference should be uniform. Check the tolerance of each point with the feeler gauge is not more than 0.01 mm. After the moving ring is installed, the moving ring should be automatically springed back after pressing the spring, and the mechanical seal is installed. When installing on the machine, it is necessary to compare with the general assembly drawing before installation to confirm whether the parts are ready. In this case, pay attention to the abnormal phenomenon such as sealing and rubbing the sealing surface and sealing ring, etc. If the filler, seal ring, etc. are in contact with the shaft or sleeve surface, flange, etc., if there is any abnormality in the seal, it must be replaced or repaired before use. The spring compression amount should be carried out according to the regulations. It is allowed to be too large or too small, requiring an error of 2.00 mm. Over the assembly, the end face specific pressure is increased, the end face is accelerated, and the seal is too small, which may cause insufficient specific pressure to seal.
