Repairing & dynamic balancing of 24mw pelton runner

A Pelton turbine or Pelton runner is a type of hydro turbine (specifically an impulse turbine) used frequently in hydroelectric plants. These turbines are generally used for sites with heads greater than 300 meters. This type of turbine was created during the gold rush in 1880 by Lester Pelton. The operation of a Pelton turbine is fairly simple. In this type of turbine, high speed jets of water emerge from the nozzles that surround

Repair and Dynamic Balancing of IHI Lance Compressor Rotor Assembly

Centrifugal compressors, sometimes called radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. They achieve a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the rotor or impeller. This kinetic energy is then converted to an increase in potential energy/static pressure by slowing the flow through a diffuser.

Failures In Pump And Predictive Maintenance

Rotating equipment is an essential part of any process/chemical/fertilizer/oil & gas or power plant and has a versatile role in operations and productivity. Due to massive rotation/use, there is always wear and tear in moving parts which may result in heavy losses in terms of productivity

What is dynamic unbalance?

Dynamic unbalance is a combination of static and couple unbalance and is the most common type of unbalance found in rotors. To correct dynamic unbalance, it is necessary to make vibration measurements while the machine is running and to add balancing masses in two planes. Dynamic Unbalance. Dynamic unbalance follows the same condition as couple unbalance and can be measured only when the part is rotating. Dynamic unbalance is present when the central principal axis of inertia neither is parallel to nor

When monitoring the condition of rotating equipment, one of the easily overlooked problems is electrical connection looseness. The Artesis e-MCM has detected the loose wire connections on an ID Fan at a wood mill in the USA. e-MCM monitoring software captured this problem

What is couple unbalance?

A couple of unbalances may be found in a rotor whose diameter is less than 7 to 10 times its width. In the case of a cylinder, it is possible to have two equal masses placed symmetrically about the center of gravity, but positioned at 180° from each other. The rotor is in static balance (there is no eccentricity of the center of gravity), but when the rotor turns, the two masses cause a shift in the inertia axis, so that it is no longer aligned with the rotation axis, leading to strong vibrations.

Predictive Maintenance In The Automotive Industry

We all know that today's demand for vehicles are much more than the ones a few years ago. It is no surprise why the automotive industry is transitioning from preventive maintenance to predictive maintenance. Due to the growing global demand for the automotive predictive maintenance market,

What is Static unbalance?

Static unbalance is an eccentricity of the center of gravity of a rotor, caused by a point mass at a certain radius from the center of rotation. An equal mass placed on the opposite side (180 deg) will balance the rotor. Static unbalance is classified as single-plane unbalance, meaning that it is represented by a single vector quantity and corrected by a single correction mass applied opposite to the unbalance location and in the axial plane of the mass center of the rotor. When there is no way to add (or remove) mass in the same plane as the unbalance

Motor Current Signature Analysis

The condition monitoring industry has been widely using vibration analysis for many years. The use of induction motors in industrial drives is quite common because they are considered dependable, cost-effective, and rugged. In fact, they even became industry workhorses because they play an essential part when it comes to converting electrical energy into mechanical energy.

Benefits of dynamic Balancing

Dynamic balancing is when the rotation does not produce any resultant centrifugal force or couple. The system will rotate without needing the application of any external force or couple, other than that required to support its weight. When a system or machine is unbalanced, to avoid stress being put upon the bearings, a counterbalancing weight is added. Dynamic balancing is a way to balance out machines by rotating parts quickly and then measuring the imbalance using electronic equipment. The imbalance calculated can then be added or subtracted from the weight until the vibration of the parts is reduced.

Predictive Vs Preventive Maintenance

Preventive maintenance and predictive maintenance focus on increasing asset reliability and reduce the possibility of failures. They are in two forms: one is to schedule the maintenance, and the other helps to schedule work in advance, rather than when they are performed. Preventive maintenance refers to regular, routine maintenance to help keep equipment up and running, preventing any unplanned downtime and expensive cost

Static, couple and dynamic unbalance

Unbalance is a result of uneven distribution of mass, which causes the machine to vibrate. The vibration is produced by the interaction of an unbalanced mass component with the radial acceleration due to the rotation, which together generates a centrifugal force. Since the components rotate, also the force rotates and tries to move the rotor along the line of action of the force.

Advantages Of Predictive Maintenance

PREDICTIVE MAINTENANCEthat uses data analysis tools to monitor the performance and condition of equipment during normal operation to reduce the probability of failures. It is a technique in which the service period of crucial parts/assets is predicted on an inspection basis so that the parts

Importance of Dynamic Balancing

Balancing is the process of correcting or eliminating either completely or partially the effect due to resultant inertia forces and couple acting on the machine parts or components. Depending on the machinery, single or dual plane balancing is used. Selecting one plane or two plane balancing generally depends on two factors. One of the factors is the ratio of the length of the rotor (L) to the diameter of the rotor (D). The other factor is the operating speed of the rotor.

Predictive Maintenance Software In Oil And Gas Industry

PREDICTIVE MAINTENANCE software is designed to analyze the performance of any equipment based on real time data and to use the condition-based monitoring that the staff can be alerted about any possible potential issues. Actually, utilizing predictive maintenance software, the degradation of any material or equipment can be analyzed from time to time so that the necessary of maintenance can be determined.

Types of Dynamic Balancing

Basically, all machines have some form of residual vibration. Enormous vibration in rotating machinery can cause high levels of noise and more importantly, significantly reduce the life of components. So, the ideal thing to do would be to remove all causes of vibration and allow the machine to run completely smooth. The process of balancing is the removal or addition of weight to the device, so that this effective mass centre approaches the true axis.The goal of balancing is to minimize vibrations related to the first order. Basically, it works like this: We measure the initial state, then we add a trial weight of the known mass

Bearing Fault Condition Monitoring Techniques

According to the International Energy Agency, more than 51% of failures in electric motors are caused by bearings. One of the root causes of the bearing problems is unbalancing, which needs to be checked continuously to avoid unexpected failures.

Dynamic Balancing of Rotor

Rotor Dynamic balancing has a direct effect on the life of any Rotating Machine and productivity. The degree to which a Rotor is out of balance is referred to as imbalance. Rotor imbalance creates force on the bearing assembly, resulting in vibration and heat, which directly affects the Machine performance. Basically, all machines have some form of residual vibration.
