Dynamic Balancing Services

Service Details:

Other Details:

• When unbalance has been identified with the help of FFT vibration analyzer, then the correction is straightforward. Weight has to be either added or removed from the rotating equipment.
• Unbalance is measured and reported in two ways. One is a measure of the effect of the vibration and the other is a measure of the heavy spot. The vibration measure is used in fieldwork and embodies the speed characteristics of centrifugal force effects. In field balancing, rotors run at their own operating speed, with minimum disassembly. A basic requirement in place balancing is that the rotor has to be accessible to make corrections.

The technique of field balancing offers some distinct advantages as:

• Balancing is performed on the complete assembled machine and hence compensates the assembly tolerances.
• The cost and time to dismantle the machine are saved.
• The possibility of damage to the rotor in dismantling and carrying it to balancing station is eliminated.
• The effects of temperature, pressure, distortion and other environmental influences can be incorporated.
• The vibration level measured at the 1*rpm is used as an indicator of the amount of unbalance. The location is determined by measuring the phase. Phase is measured by an indicator in the instrument, triggered by a photocell.

Service Details:

With the thorough knowledge of the industry, we are engaged in offering services for Magnetic Particle Inspection. Our professionals utilize advanced machines a follow industry guidelines while rendering these services. Offered service is based on non-destructive methods which are used for the detection of surface and sub-surface defects in the ferrous material. In order to maintain higher standards, a team of experts keeps vigil at every stage.

Following are some of the details of the service offered by us:

• Removes the material flux from the area of the flaw
• Uses an externally applied magnetic field or electric current
• Deformation of the magnetic field extends to a considerable distance
• Size of the distortion is much larger than that of the defect
• Distortion is made visible at the surface of the part by means of the tiny particles attracted to the leakage fields
• Common method of magnetic particle inspection uses finely divided iron or magnetic iron oxide particles
• Suspension is sprayed or painted over the magnetized specimen during magnetization
• Magnetic particles are attracted by the surface field in the area of the defect
• Magnetic particles are held on to the edges of the defect
• Inspection can be applied to raw material in steel mills in the early stages of manufacturing
• Also used for inspecting structural parts

Common test methods:

• BS6072: 1981 (1986 - AMD 4843)
• Magnetic Flow
• Color Contrast Method
• ASTM E709
