Machine installation is one of the most important processes of industries and appropriate machine installation helps to maximize the consistency and it also minimizes the life cycle cost.
And inversely bad Machinery installation may lead to many losses like it may cause the formation of poor quality products, it may reduce machines capacity and these factors may lead to high production costs. Installation requirements are different which depends on each individual machine and its functions, few of the instructions that must be followed while machinery installations are discussed below.
The first thing that has to be checked is to find out that whether the foundations where machine have to be installed are stiff and strong enough that the machine will work almost in state of equilibrium. If there is lack of mass or stiffness in the foundation then it may cause operating forces to produce uncharacteristic vibrations that degrades the machine and increases the cost of maintenance of machines. Foundations are to be such that they can withstand the applied load from outside that too without any resolution, flexing or devastating. Foundations of heavy machines are made up of concrete or steel structures. Foundations of heavy machines are made either by making concrete pad which is made by pouring concrete and making a pad that has enough stiffness and mass to absorb the abnormal forces produced by the machines.
The machines are bonded to the foundation by the anchor bolts. Permanent methods used for anchoring confirms the fix and permanent fitting of parts. In the process of machine installation when the machines are anchored to foundations made up of concrete, j- bolts are embedded into the concrete foundation at the time of pouring concrete. The machines are held by size bolts so as to withstand holding torque and also to prevent machines from loosening their position by loosening of bolts with time.
When machines are operated they generate vibrations and these vibrations are either absorbed by the foundations on which they are held or are absorbed by machines only. The term cross talk also takes place in this process vibrations produced by one machine are absorbed by other machines and this also constitutes for the reliability problems. This problem mainly occurs in the places where there are plants of machines that are where a number of machines are installed in an industry like paper printing units, metal processing units etc.
