On-Site Balancing and Vibration Problem Solving Service

For 25 years 3E has brought this service to its customer's doorstep. With state of the art equipment, balancing, alignment and vibration related problem solving for fans, mills, rotors, pulleys and various other rotating equipment is routine.

Predictive Maintenance using Vibration Analysis

Predictive Maintenance is a process of determining the expected running condition of rotating machinery to predict the longest possible period of life a unit can operate before a failure occurs. In other words "If it's not broke why fix it".

Rotating equipment can be categorized into three basic conditions.

• Healthy
• Sick
• Dead

Ideally when a unit has been running in a healthy state and becomes sick there is plenty of time to order parts and schedule a shut-down to make the necessary repair before the unit becomes inoperable, causing expensive downtime.

Predictive Maintenance is a three-step process.

1. A vibration technician visits the job site and with the customer determines the production importance of the various machinery to be tested. The name of the machine is recorded and without shutting down, vibration data is taken along with some condition analysis. After gathering the data on-site, 3E's vibration technician will enter the data into 3E's computer system. Depending on the style of a particular machine the analyst determines the condition of the unit and sets vibration alarms in the computer program at various levels of amplitude.



2. Based on the vibration analysis, the technician works with the customer to make repairs or corrections to any unit that is deemed to be in a sick or dead state. Achieving a healthy state could involve balancing, alignment, mechanical repair, structural improvements, etc.



3. The final step is to begin a program of scheduled vibration data collection making it possible to keep a continuously updated record of machine vibration history commonly known as trending. Comparing this history with recent data aids in the detection of faults and gradual deterioration of the machines condition.

These three steps are the basis of a reliable predictive maintenance program.

Solid State Repair

Inverters, speed controls, and various circuit boards can be repaired on-site or at 3E's facility.

Uninterruptible Power Supply (UPS)

A UPS provides power to critical equipment in the event of power loss. As businesses become more dependent on the continued operation of electrical and electronic devices the need for UPS systems is crucial.

The UPS has other benefits in addition to power loss protection. Many brands will condition the power by providing protection from line noise, power surges, brownouts and voltage variations. This added benefit saves wear and tear on hard drives and other critical electronic equipment.

UPS systems provide protection to many types of equipment including:

• computers
• emergency lighting
• telecommunication
• food preparation and storage
• data processing

UPS systems are often neglected because they are not noticed until a power failure. With time, undetected problems can develop that could result in damaged equipment or loss of data.

At 3E we recommend routine preventative maintenance and testing to avoid failures in your UPS system. A UPS in good operating condition provides security. Why wait until it’s too late?

Our typical service includes:

• battery testing and replacement
• inspection and repair of solid state charging circuits and components
• inspection and repair of bad connections

Hoist Inspection and Repair

The proper testing of overhead hoists and lifting equipment is of critical importance to employees and the employer. The potential liability savings usually offsets the cost of such inspections. Regular inspections may significantly reduce repair costs and prevent catastrophic failures.
