Ing. Enrique Dounce Villanueva LET US TALK ABOUT INDUSTRIAL PRESERVATION.

LET US TALK ABOUT INDUSTRIAL PRESERVATION INTRODUCTION In some of my works I have mentioned that my first contact, from a scientific point of view, with different aspects of Industrial Maintenance, was during a Maintenance Congress that took place from June 4 to 15, 1962 in Stockholm, Sweden. I was invited to attend it by L M Ericsson, phone equipment, manufacturer and supplier. This event awakened in me a profound interest in Industrial Maintenance, mainly focused in communications. Since then, through my 25 years of experience in “maintenance” work at Telefonos de Mexico’s phone plant, and later, until my retirement in 2002 as Consultant and Lecturer in this branch of Mexican industry, I have closely followed its evolution, I have written books and articles, I have attended numerous congresses on the topic and I have expressed personal initiatives about this subject to Mexicans and foreigners. I now see with satisfaction that I have a considerable amount of my own work, plus the time and age to sow. Our work has led us to verify that at world level, there is a dangerous confusion that calls “Maintenance” to what is actually “Conservation” thus constantly harming our habitat. We have always thought that it is important to correct this mistake. Since 1984, we have requested help in writing to obtain a forum to present our ideas. We have many letters sent to relevant persons and entities in our country such as CONCYT (Science and Technology Council), UN (United Nations), SEP (Department of Education), our last two Presidents, and hoping for better results, we have presented in “Initiative Mexico” in 2010 and 2011, the idea “Let us learn to care for our planet by scientifically training Industrial Conservation teachers”. We have presented our thesis once and again without tangible results. Moreover, the works we have developed continue to be accepted worldwide. In 1989, we introduced “Industrial Conservation Taxonomy” which can be found in the net. In 2009, we wrote “The Principle of Industrial Conservation”; in 2010 and 2011, “Initiative Mexico” and at present we are writing a new book that will gather, in a holistic manner, the concept of Industrial Conservation. Wtihin this context and taking into account that is essential and urgent to find physical and moral persons determined to study in depth this problem, we are inviting persons in the educational circles in our country to join in our effort. For your information up to this time, our research has led us to feel that the above mentioned mistake is due to the fact that “Maintenance” is being called indiscriminately Conservation and Preservation causing serious problems in the appropriate administration of this subject. Our current work consisted in analyzing the differences made by some Technical school, Universities and Technological institutes, well known in our circle so we decided to get near them through the net to verify how they handle these concepts in the following entities:

NOTE: The initials in parenthesis stand for the Spanish names of the Departments and universities as follows: SEP = Secretaria de Educacion Publica = Department of Education STPS = Secretaria de Trabajo y Prevision Social = Labor and Social Welfare Department UADE = Universidad Argentina de Empresas = Argentinian University of Business UAM = Universidad Autonoma de Madrid = Autonomous University of Madrid

We suggest that our guests read this article with a mind open to change. We will present the entities in the above mentioned order , therefore, we will first present the results we obtained with: 1.- General Directorship for Job Training (SEP) (STPS, 2011). They work through CECATI (Training Center for Industrial Labor) in which they teach, among others a course called “Industrial Maintenance”. We got this report from the net.

You can see the absolute lack of coherency in the use of the terms employed. The persons doing the advertisement, certainly with a lot of care, take the words Industrial Maintenance, Maintenance, and Conservation as synonymous: that is, they consider all these terms as having the same or similar meaning. However, the students of this course are being trained exclusively in the Preservation of the different mechanical devices in the industry and the Preservation of facilities and pumping equipment, which are, mainly, Industrial Preservation tasks, as mentioned by the arrow placed by our analyst. (STPS, 2011) Mexico. 2.- Social Welfare and Labor Department (STPS for its initials in Spanish) At the Social Welfare and Labor Department we also find these concepts included under the name of maintenance, for example for the degree in “Mechanics, Repairs, and Maintenance”, for which it is mentioned that it deals with machinery’s operation, maintenance and repair, as well as facilities and equipment for mechanical and industrial processes. See how many synonyms were used and they never mention Preservation which is the true role of the subject they are teaching. It is the same focus for all other degrees or courses they offer.

3.- Technological Universities System (SEP) (SEP, 2011) Mexico. Within the Public Education Department, the Technological Universities system offers degrees in four areas, from which we analyzed in depths the industrial electro-mechanical area and its degrees, such as “Production Processes”, “Industrial Maintenance,” “Industrial Electricity and Electronics”, etcetera; where we found the already mentioned confusion, citing as an example courses such as “Computer equipment maintenance”, “Hydraulic and pneumatic machinery maintenance”. “Shaping processes machinery Maintenance”, “Automation and Robotics equipment Maintenance” etcetera. Analyzing the above, we can see they are talking about “Preservation”, and not maintenance. 4.- National Autonomous University of Mexico (Moltalvo, 2011) Mexico. We analyzed the use of this criteria en the “Writings about productive Systems design”, done by an Industrial Engineering Professor at this school, in which in section IV.3, he writes about “Types of Maintenance”. Studying this subtopic under the focus here proponed, we again find the inappropriate use of these concepts.. 5.- Monterrey Institute of Technology (ITESM, 2011) Mexico. We studied the degree plans that have some relation to Industrial Conservation such as “Sustainable Development”, “Industrial and Systems Engineering”, and “Electrical and Mechanical Engineering”; etcetera but we did not find any mention of maintenance, Conservation, or Preservation. In 1999, when this subject was still taught, it was considered an optional subject. 6.- Argentine’s University of Business (UADE) (UADE, 2011) South America. We studied their “degree plans” for example, 3.3.702- “Production Organization” and within its contents we could verify that they talk about “Maintenance operation” confusing it with Conservation.

7.-Madrid’s Autonomous University (UAM) (UAM, 2011) Spain. We thought it was important to analyze the criteria followed by this university to hire some “maintenance” services. Again, we used the net to visit this university’s site, opening in “UAM and the media”, followed by “public contracts” and requested “services”, finding A- 212 Maintenance and repair services for Electronic equipment and wíreless net programs for UAM and within its parts for “technical prescriptions” we analyzed topics 7, Maintenance service description, and 8, Maintenance detail, again finding very clearly the same concept confusion. With the objective of placing within a context what we have so far analyzed, this to help us understand the importance for the world to know the Industrial Conservation branches. Let us see Figure 2 to obtain a concept for Preservation.

Figure 2 Industrial Conservation Branches We define Industrial Conservation as the human action on a system, which, through the application of scientific and technical knowledge, contributes to the optimum use of existing resources, thus working towards the integral development of man and his ecosystem. It is divided in two branches, one is Preservation which refers to the care of the quality of the system’s material aspect, and the other is Maintenance which focus on caring for the quality of the service provided by such matter. Let us now talk about the motive for this analysis: INDUSTRIAL PRESERVATION For a system to reach its expected life time (trustworthy operation for “n” hours) it is necessary to think carefully how to protect it from wear and random failures. For example, within a forest, we need to remove fallen, old, or dead trees, plant new trees, fumigate, etc. We can find other case in an generating set in which we can see that it needs, among other things, oiling to decrease wear, fuses to protect its electrical circuits, cleaning to avoid damage due to dust, etcetera. We must analyze any resource we want to protect and plan carefully the tasks that need to be performed. This task is called Preservation and is focused exclusively in taking care of the matter and not on the Service it performs. Preservation is defined as human action performed to protect from material damage the resources existing in the habitat. There are two types of preservation, Preventive and Corrective and the difference lies in whether the work is done before or after a damage has occurred to the resource. Septiembre 2011. Copyright ©

For example, to paint a Hopper just installed is a task for Preventive Preservation but if it is done to repair it, then it will be a Corrective Preservation task. We must be aware that the matter that comprises an item during its life requires to always be cared for by one of these types of preservation. According to the importance of the tasks to be performed for the item, Preservation includes three sequences or action to follow, Periodic, Progressive and Total (Figure 3).

Figure 3 Preservation Periodic Preservation refers to the rational care and protection for a machine during and in the place it is operating. It is divided in two levels; the first level corresponds to the resource user, and the second level to a middle technician (Figure 4).

First level. Defines Preservation tasks and frequencies for the operator to apply to the resource. As a first responsibility, the operator must know in depth the operation manual and the careful performance of preservation tasks assigned to him (cleaning, oiling, small adjustments, minor repairs). All these tasks are usually performed on the site where the machine is operating. Second level. Defines the Preservation tasks and frequencies that a middle technician must apply to the resource when there are anomalies in their operation. Therefore, more Septiembre 2011. Copyright Š

knowledge is needed, Tools, and testing machines are required in order to be able to perform “First Aid” tasks to the item at the operation site. Progressive Preservation. After a long operation time, machines must be checked and repaired more in depth. This requires that it be done outsider of the operation site, with more specialized personnel, tools, and diagnosis tools. In some cases, it is economically more feasible for companies to have their own personnel and shops to attend to the tasks on these equipments that require frequent handcraft tasks; in other cases, when a more specialized preservation job is required, it is better to hire workshops nearby. Due to the above, this type of preservation is divided in two levels (Figure 5):

Figure 5

Third level (Technician). When the attention is assigned to the factory’s general Workshops, which must employ personnel with strong handcraft characteristics, since good labor is more important than analysis work. Fourth level (Specialists). When the attention is assigned to third parties with specialized personnel and shops, usually to perform Preservation tasks focused on specific areas of the company (Air condition, electricity or internal combustion motors repairs, civil engineering or electrical jobs, plumbing, etcetera). Fifth level, Total Preservation (Overhaul). It means to check and repair an item until it arrives to a desirable condition, which can be its original condition (new, where all its parts are also new), or it can be taken to intermediate conditions. High cost physical assets (airplanes, ships, trains, etcetera), are subject to this type of preservation to extend their useful life.. Septiembre 2011. Copyright ©

This type of preservation requires, in the first place, a person responsible for the total result obtained, who will supervise the labor of the work teams. These work teams should have in depth knowledge and abilities about the design, functioning and operation of the item’s part in their care, as well as about the handling of tools and test machines which are to be used. With the objective of ordering the definition of the different Overhaul levels, the USA Federal Aviation Administration (FAA) has recommended a series of rules applicable to any type of motor. For example, this entity considers that only an item’s manufacturer is capable of rebuilding it to its original specifications.

CONCLUSION As we have seen, we have verified that the educational entities which are created to provide for us the culture of Industrial Conservation are really disoriented, and confused, in spite of the daily effort we put forth to obtain good results, in spite of the great men and healthy will involved at world level in this task. The ideas brought about by Industrial Conservation have created a “Gordian knot” that makes it difficult to understand the essence of these topics. However, a Joint battle of good wills and providing creative solutions to discover the root of the problem in order to disclose all the existing implications. Cited works ITESM. (2011).
