Because the Artesis system is simple to install and requires little user intervention in operation, it combines low start-up costs with the significant benefits of predictive maintenance. Since it doesn’t require any sensor installation on the equipment itself, and it can be installed in non-EX areas, Artesis eMCM is a particularly good solution for inaccessible equipment in the automotive industry.

Service Details

Typical applications where you can monitor either electrical, mechanical and process conditions:

There are a lot of moving parts in this area, being the main ones, of course, the stamping and pressing machines. Usually, several presses are linked together to create a multi-stage forming line.

These lines have conveying systems driven by electric motors that need to be monitored. Also, most of the presses are pneumatic and require an air compressor for the pressurized air supply. Monitor your conveying systems and compressors with Artesis monitoring technology and reduce downtime at the press shop.

Do not forget any motor-driven equipment can be monitored, so decoilers and other equipment from the palletizer can be monitored too.

In the body-in-white stage of the automotive production, it is very important to ensure reliability to keep the flow of material towards the painting process. Again, conveyors are very important and monitoring their condition is essential. Also, with Artesis monitoring units, you can keep an eye on the condition of automated turn tables and welding tools as they are motor driven machines.

Again, many tools in this stage require a supply of pressurized air. Monitor the compressors for the body-in-white stage with Artesis technology. Sometimes storage is needed and done in a vertical fashion by means of lifts. Monitor the drives of the lift and ensure this task is done properly.

Again, as this is a step in a process, the parts are moved around with conveying systems and they should also be monitored. Monitor the water pumps that supply the water needed for the rinsing baths and washing booths used in surface treatment.

Ventilation is an important part of the painting process in the automotive industry. Monitor the fans used to supply fresh air and extract the polluted air. Artesis technology helps you detect problems such as misalignment and imbalance on the motors and fans.

In addition, monitor all the pumps used for the paint supply, the real heart of the painting stage.

The powertrain parts are usually cast in a foundry. For a foundry to properly work there are pumps that supply water for cooling. Monitor these pumps and the fans of the cooling tower. Also monitor any conveying systems and machine tools used to finish the parts.

Monitor the air compressors that are used for the pneumatic tools used in the engine and gearbox assembly. Also, tests are a very important part of the stage and the test rigs should be monitored so the results can be accurate.

Again, a lot of conveying systems form part of this stage and Artesis helps you monitor the condition of their drives and any other motor-driven equipment of this stage.

CASE STUDIES

Nissan Case

This section gives the details of the implementation of the Artesis early warning system at the trim & chassis department of a car manufacturing plant (Nissan) in the United States.

In the conveyor PSD graph, the sidebands around the line frequency (60Hz) are the indicators for transmission element faults. 17Hz sidebands are due to something running at 1020 rpm in the cyclo (transmission).
The figure gives a snapshot of the equipment by an existing monitoring system in the plant. The accelerometer next to the cyclo has a yellow indicator, meaning that the peak vibration at that sensor was reached the warning level.

This corroborates MCM’s analysis of transmission element fault detection. The 2OH-1 GB1 Peak scale shows that it has exceeded the warning threshold, which also confirms the early warning system’s findings.

Cooling Tower Fan Looseness

In this example, a global automobile manufacturer had installed MCM monitors on a number of cooling tower fans. Because of their physical inaccessibility, these fin fans had proven to be expensive and difficult to monitor with other methods.

The Artesis early warning system gave its first warning on Oct.16th and diagnosed the problem as mechanical looseness. However, the severity level remained low, and over the next few days, the alert was cleared. Based on the diagnosis, the plant staff decided to defer action but to watch closely for further occurrences of the problem.

Gradual deterioration in fan condition led to a renewed alert on Nov. 19th. This time, the alert remained in effect consistently at a moderate severity.

Maintenance inspection was not made until February 14th, during which time a loose attachment bolt was discovered at the point where the fan hub is attached to the driveshaft flange – validating that the initial MCM diagnosis had been correct. Following the correction of the loose fastener, the system remained in alert, accurately identifying a continuing mechanical unbalance condition which may have been related to the original problem.
