We are able to undertake work on many pumps and are specialist in the shaft repairs, reconditioning and shrink fitting, machining of rings, bushings and linings.
All components of an assembly that are required to rotate should be balanced, examples of such components are fans, rotors, impellers and shafts. Imbalance in a part causes unwanted vibration which in turn can cause many other problems such as increased wear to components, loud noise, decreased performance of components and catastrophic failure.
Dynamic balancing is a method of measuring the imbalance in a component using electronic equipment whilst the part is rotated at high speeds, once imbalance is measured it can be corrected by adding or removing material from a part in the appropriate location. In some cases a part may become imbalanced due to bending and can be corrected using a procedure of straightening.
At our UK based facility in Dorset UK we can provide balancing services for shafts motors up to 3 tons. We use an overhead crane capable of carrying up to 10 tons.
Shrink fitting is a method of fitting components that use an interference fit, it does this using thermal contraction i.e. a component such as a bushing can be cooled using liquid nitrogen (LN2) which causes it to become smaller and easily fit into it’s register until it returns to ambient temperature and it’s original size. This method is better than fitting the components using force or heat because it won’t damage the surfaces of the components.
