Maintenance to electric motors

Maintenance to electric motors

BOBINADO-min
From steam cleaning to laboratory testing are just a few of the activities that take place when it comes to electric motor repair.
 

The field of action of electric motors covers several areas within the industry, which is why the output of this equipment can represent economic losses.

The maintenance of electric motors is an extremely important aspect because they are equipment for continuous use, so their components are exposed to wear, as well as contamination by agents such as dust, grease and humidity.

In the maintenance of electric motors, certain protocols are followed in order to establish the actions to be taken: Inspection, disassembly, as well as the verification of electrical and mechanical components.

The inspection phase contemplates a series of tests that are used to make an accurate diagnosis, such as verification of insulation resistance, motor continuity, direction of rotation.

Gustavo González, an engineer specializing in rotating equipment at Corporación BD, explained that the “tests make it possible to collect data on the operation of the equipment, for which dynamic and static tests are carried out to help detect or predict any failure.” Among the tests are: Polarization Index, Inductance, Capacitance, Impedance, Resistive Unbalance, Insulation Resistance, High Potential Tests, among others.

After the diagnosis is made, we proceed to the disassembly area where the electrical and mechanical parts are divided. In the case of mechanical elements such as bearings, shafts, covers, a cleaning is carried out to remove any residue and thus proceed to carry out a dimensional inspection.

Steam washing helps to remove substances that can deteriorate the motor’s insulation. Before the assembly of the winding, sandblasting is carried out as well as the internal and external mechanical polishing of the motor.

 

Rewinding of electric motors

When motors suffer damage to the coils, it is necessary to remove the winding and replace it with a new one in order for the motor to function correctly again.

There are many causes that can cause motor winding damage, some of them are:

– Overheating

– Short circuit in the connection butts.

– Short circuit between two phases.

– Peak voltage

– Short between phases

– Rotor lock

At Corporación Business, through the b&Maintenace business line, we have specialized technical personnel, workshops with test benches for horizontal and vertical motors up to a capacity of 15,000 Hp. In the same way, there are portable workshops to carry out work for motors with a capacity from 1/2 Hp to 600 Hp.

Regarding motor rewinding, we work with low and medium voltage AC equipment (up to 6,600 V / 15,000 hp), AC and DC slip rings (generators and traction rotors), DC pole rewinding and Polar Wheel.

Augmented and virtual reality in industrial maintenance

Realidad aumentada y virtual en el mantenimiento industrial

PORTADA-5 (1)
 

This technology is increasingly used in maintenance operations

Augmented Reality (AR) is a term that refers to those technologies that incorporate virtual elements in a graphic way to the real world; For its part, Virtual Reality (VR) consists of the integration of elements or objects created artificially but that have a real appearance.

The development of this technology has allowed it to be useful in Industry 4.0, opening up wide possibilities in the maintenance area.

One of the first applications of these technologies was immersive training, taking an important step in technical training. In the same way with augmented reality devices it is possible to obtain information about:

  • Process simulation.
  • Visualization of labels.
  • Remote fault diagnosis.
  • Maintenance records.
  • Visualization of plans, documents, machinery data, among others.

Virtual and augmented reality in maintenance activities allow technical staff to have access to information about equipment in real time, that is, an augmented reality system, for example, can take data from a machine to project it on a smartphone, tablet or glasses so that an operator has that information while they are working.

Both technologies provide the opportunity for companies in the industrial sector to start the path towards digitization and take advantage of the benefits it brings, such as:

  • Improvements in the security issue
  • Process improvement
  • Costs reduction
  • Reduction of waiting times

Importance of Industrial Maintenance

Importance of Industrial Maintenance Good maintenance management allows a company to be useful and competitive

DSC_0041

 

When talking about industrial maintenance, it refers to the application of a set of techniques or actions in order to conserve as long as possible and at maximum performance, both to facilities and industrial equipment.

According to the working conditions, the machinery can present breakdowns, wear parts or have low performance, which is why maintenance is important because it seeks to extend the useful life and efficiency of equipment belonging to any industrial process, which allows The organization is competitive and generates profits.

When talking about industrial maintenance, it refers to the application of a set of techniques or actions in order to conserve as long as possible and at maximum performance, both to facilities and industrial equipment.

The benefits of Maintenance in Industries

  • Increases the useful life of equipment.
  • Reduce costs.
  • Avoid irreparable damage to machinery and facilities.
  • Prevents accidents at work.
    Quality in production.
  • Reduces costs due to production stops.
  • It allows a correct use of the budget.
  • Better control of the state of equipment and machinery.
  •  

The risks for a company that does not have an adequate maintenance plan

Poor management, low budget, low proportion of hours spent on preventive tasks and a technical staff focused on correcting faults, put any industrial facility on alert.

Not having clear guidelines on maintenance puts at risk not only the integrity of industrial equipment and facilities, but also represents a danger to workers. In some cases there is a company that does not have the necessary technical structure to manage and create specific policies that allow the control of each machinery and equipment, which further complicates the panorama.

Corporación BD is an ally of the industry, and it is that through its business units in the area of ​​Maintenance and Engineering, it provides solutions in the planning and execution of maintenance in different areas:

  • Mechanical maintenance
  • Electrical maintenance.
  • Instrumentation.
  • Civil and refractory.
  • Special welds.

Reliability engineering applied to maintenance

 
Industrial Services: the heart of petrochemical plants

Through RCM, improvements in equipment reliability and plant performance can be achieved.


Reliability Centered Maintenance, also known as RCM (Reliability Centered Maintenance) is a methodology used in the preparation of maintenance plans, which is derived from reliability engineering and which seeks to reduce the probability of failure of the assets of an industrial plant. .


For Jesús García, Director of Operations at Corporación B&D, reliability engineering is a fundamental pillar in any production process, because it guarantees the availability of a plant. “In our case, we have developed and implemented reliability engineering tools, such as RCM, this has allowed us to analyze recurring failures that may be present in a system.”


RCM Benefits


    

  • Decreased maintenance costs.
    • 

  • Increased production.
    • 

  • Reduces delays in work orders.
    • 

  • Improves team control.
    • 

  • Maximize maintenance operations.
    • 

  • Less dependence on the manufacturer.
    • 



However, this methodology does not provide an instant solution to all maintenance problems in a plant, it is a technique that if you know how to use it gives good results; This is where experience and knowledge play an important role in the implementation of this type of tool.


García explains that when implementing this type of methodology it is necessary to collect all the information on the asset such as manuals, plans, know the operational context, conduct interviews with production and maintenance personnel to find out what problems are occurring, all of this. based on international regulations. “For example, the collection and structuring of maintenance and reliability data is carried out in accordance with ISO 14224, which, although it is aimed at the oil, petrochemical and natural gas industry, can be adapted for application in any industry. that has physical assets in the processes”.
