A Brief Discussion on the Life Cycle Cost Theory of Air Compressors

This article carefully analyzes the cost of air compressor equipment throughout its life cycle from the perspective of users. First of all, air compressors are general equipment. Air compressors can be found in civilian hospitals and medical fields, industrial manufacturing companies, construction markets, and transportation operations. A small device can ensure the normal operation of the entire system. Running. Then the air compressor consumes energy and incurs costs during the actual purchase, installation, equipment use, and the end of the use period by the user until the equipment is scrapped. In the purchasing decision-making stage, users are required to analyze effectively and what analysis tools to use are the most headaches for users. This article would like to share with you the theory of equipment life cycle cost, guide the purchase of equipment to the end of its use period, and pay attention to the cost of equipment life cycle. After all, it is not only the one-time purchase cost of equipment, but also equipment operation and maintenance costs. Considering.

1. The source of equipment life cycle cost

The so-called life cycle cost is the total cost of equipment scrap from the end of the equipment purchase period. The total cost of the equipment life cycle can be studied to evaluate and compare various options to obtain the best long-term cost. income. It is generally expressed as LCC (life cycle cost), and sometimes WLC (whole life costing).

The life-cycle cost of air compressor equipment is the total cost of the air compressor in the predetermined life cycle due to the demonstration, selection, purchase, installation, use, maintenance and protection of the air compressor, including direct and indirect costs. Costs, recurring and one-time costs and other costs related to them.

　　The research and definition of the life cycle of equipment mainly include physical life, functional life, legal life and economic life.

　　 (1) Physical life, under normal use, from the bidding and procurement stage of the equipment to the entire period of time that the basic functions of the equipment cannot meet the normal use of the user due to the physical damage of the equipment, it is called the physical life. The physical life of equipment is affected by various aspects such as natural disasters, social disasters, and equipment quality.

　　 (2) Functional life, any device is to meet the needs of a certain function of the user. The functional life span is the time period before the equipment can meet the needs of the owner after the equipment is purchased, installed, and delivered. The loss of equipment function is mainly caused by changes in user needs, physical consumption and other reasons. The functional life of the equipment depends on both the quality factors of the equipment itself and the proper operation and maintenance factors of the user. These internal and external factors are random, so the functional life of the equipment has Uncertainty.

　　 (3) The legal life span is the reasonable service life of the equipment stipulated by law, and is also the reference guarantee life provided by the equipment manufacturer to the user.

(4) Economic life, the time from the beginning of the life of the equipment to the continued use of economically unreasonable and renewal. It is determined by the increase in operation and maintenance costs and the decrease in use value. The longer the service life of the equipment , The less asset consumption cost is allocated, but the increase in equipment service life requires more operation and maintenance costs to maintain the original functions; on the other hand, the energy consumption of the equipment will also increase, so the annual asset consumption cost The reduction will be offset by the increase in annual operating costs. Therefore, the economic life of equipment is to determine the cycle life of equipment from an economic point of view (or cost point of view).

　　 2. Equipment cycle management stage

　　 Three stages of equipment life cycle management:

　　 Pre-stage management, the pre-stage management of equipment includes the entire process of planning, decision-making, planning, research, purchase, installation, commissioning, and trial operation.

　　Operation and maintenance management, including daily maintenance, inspection, monitoring, diagnosis, repair and update management to prevent equipment performance degradation. Replacement and obsolescence management includes the repair and maintenance of some repairable equipment, and the continued reuse. The entire equipment has reached the end of its service life and has frequent failures, which affects the reliability of the equipment unit. The maintenance cost has exceeded the equipment purchase cost and must be replaced. The replaced equipment assets are sold or transferred, and the corresponding expenses are used for cost and income, which is also the official end of the equipment life.

　　 Three, equipment life cycle cost structure

　　Equipment cycle cost refers to all the expenses incurred during the equipment life cycle. The choice of equipment life cycle of different brands not only affects the cost composition, but also affects the length of the cost calculation period. During cost analysis and research, clarify the scope of its life cycle and choose a unified standard as the basis for comparison and selection of equipment of different brands.

A Brief Discussion on the Life Cycle Cost Theory of Air Compressors

Cost price management throughout the life cycle is the focus that all air compressor users need to pay attention to. Its significance is to guide people to consciously and comprehensively start from the entire life cycle of the project, and comprehensively consider the cost of equipment bidding and procurement and operation and maintenance costs. , From a number of different feasible programs, in accordance with the principle of minimum life cycle cost, select the best procurement cost program.

From the perspective of environmental protection and ecology, and considering the issue of purchase price and cost from the perspective of the whole life cycle, people can adopt reasonable planning and design in all aspects of the whole life cycle, and adopt energy saving, water saving, electricity saving and saving. The layout of the space is designed to be economical, pollution-free and environmentally friendly, and measures are in place at one time. Therefore, under the premise of minimizing the cost of the whole life cycle, the purpose of environmental protection and ecology is achieved, and the use efficiency of the equipment is improved.

The composition of the total life cycle cost includes initial investment, operation and maintenance costs, replacement costs, historical operating costs and current costs of a certain brand through industry-related data analysis, and predicted future costs. It is the user's choice of the entire life of the air compressor industry. The core content of cycle cost. The ultimate goal of the air compressor equipment industry practitioners is to minimize the life-cycle cost or maximize the life-cycle cost and profit.

　　 Four, summary

Therefore, in the air compressor industry, the goal of continuous improvement of the equipment life cycle cost is realized, so as to achieve the coordination and unification of technology, economy, society, and ecology. The user and the user have the lowest cost in the life cycle. It should be based on the technical and economic aspects of the equipment. Take measures to achieve technical feasibility and economic rationality. The main content of cost optimization during the use phase of the equipment includes the water and electricity consumption of the equipment, the integrity of the equipment structure, components, and facilities, and regular inspections, predictive inspections (maintenance), and post-repairs (maintenance). It is necessary and necessary for us to make air compressor life cycle cost statistics, and it is also an effective analysis tool for the purchase decision of air compressor units.
