How to evaluate the service life and performance degradation of industrial ultrapure water machines?

Industrial ultrapure water machine is a kind of equipment used to prepare ultrapure water. The evaluation of its service life and performance degradation is very important to users. The following will discuss in detail from two aspects: service life and performance degradation.

I. Evaluation of service life:

1. Equipment life: The equipment life of industrial ultra-pure water machines refers to the time that passes from the time the equipment is put into use to the time the equipment cannot operate normally. The evaluation of equipment life can be carried out through a comprehensive evaluation of the equipment's materials, design and manufacturing processes to determine the expected life of the equipment.

2. Frequency of maintenance: Industrial ultra-pure water machines require regular maintenance during use, including cleaning and replacement of filter elements. The higher the frequency of maintenance, the shorter the service life of the equipment.

3. Operating environment: Different operating environments will also have a certain impact on the life of the equipment. For example, if an industrial ultrapure water machine is used in a high temperature or high humidity environment, its service life may be relatively short.

4. Preventive maintenance: Regular preventive maintenance of equipment can extend the service life of equipment. For example, regularly check the pipes, valves, electrical components, etc. of equipment to ensure their normal operation and identify and deal with problems in a timely manner.

5. Raw water quality: The service life of industrial ultra-pure water machines is also affected by the quality of raw water. If the raw water contains high concentrations of impurities such as dissolved solids and suspended solids, these impurities will cause corrosion and blockage to the filter elements, diaphragms and other components of the equipment, shortening the service life of the equipment.

6. Equipment load: Equipment is used according to the design workload of the equipment. Excessive water load will lead to rapid aging of the equipment and shorten its service life.

II. Evaluation of performance degradation:

1. Water quality inspection: The performance attenuation of industrial ultrapure water machines is evaluated by regularly testing the water quality of ultrapure water, including indicators such as conductivity, dissolved oxygen, total dissolved solids, and total bacterial count.

2. Filter element replacement cycle: Filter elements are frequently replaced components in ultrapure water machines, and their replacement cycle can be used as an indicator to evaluate equipment performance degradation. If the filter element replacement cycle is shortened, it means that the purification effect of the equipment is reduced and the performance is attenuated.

3. Water outlet flow: The water outlet flow of industrial ultrapure water machines is an important indicator. If the water flow rate drops significantly, it means that the performance of the equipment is degraded, which may be caused by a plugged filter element or other failure.

4. Water quality change trend: Through long-term monitoring of the water quality processed by industrial ultra-pure water machines, the performance degradation of the equipment can be evaluated. If the water quality remains stable for a long time, it means that the performance of the equipment is stable; if the water quality continues to change, it means that the performance of the equipment is declining.

5. Equipment operating status: The operating status of the equipment can also be used as an indicator to evaluate equipment performance degradation. For example, increased operating noise, increased vibration, frequent failures, etc. may indicate that the performance of the equipment is declining.

Summary:

Evaluating the service life and performance degradation of industrial ultrapure water machines requires comprehensive consideration of multiple factors, including equipment life, maintenance frequency, operating environment, preventive maintenance, raw water quality, equipment load, water quality inspection, filter element replacement cycle, outlet Water flow, water quality change trends and equipment operating status, etc. Only by comprehensively evaluating and monitoring these factors can we accurately determine the service life and performance degradation of industrial ultrapure water machines, and make corresponding maintenance and replacement decisions to ensure long-term stable operation of the equipment.
