Today, our economy is more and more developed, not only our economy, even our other aspects are the same, also become developed, the most obvious is our industry, mechanical spare parts processing is also the same, so what do you need to pay attention to when installing machinery?
1, to pay great attention to avoid the installation deviations arising from the installation.
(1) tighten the gland should be carried out after the coupling is corrected, the bolt should be evenly supported on to prevent the gland end deflection, check the points with a stopper, the error is not more than 0.05 mm.
(2) Check the fit clearance (i.e. concentricity) between the gland and the outer diameter of the shaft or sleeve, uniformly all around, and check the tolerance of each point with a stopper no more than 0.01 mm.
2, the spring compression amount to be carried out in accordance with the provisions, do not allow too large or too small phenomenon, requiring an error of 2.00 mm. Too large will increase the end surface pressure, another speed end wear. Too small will cause insufficient pressure and can not play a sealing role.
3, after the installation of the dynamic ring beard to ensure flexible movement on the shaft, the dynamic ring pressed to the spring should be able to automatically spring back.
