Calculating the Replacement Cycle for Consumables for Laser Smoke Purifiers

It provides a practical method for calculating the replacement cycle of consumables for laser smoke purifiers, combining the usage environment of the equipment with the regularity of consumable wear and tear to help users accurately plan maintenance times and avoid the cost of over-replacement or delays.A case study of how to calculate the costs of key consumables such as filter cotton and activated carbon will help you master the techniques of cost-saving maintenance.

Why is it necessary to accurately calculate the replacement cycle?

Many friends think that "when they need to be changed, they should be changed.In fact, the lifespan of consumables such as the filter cotton and activated carbon in the laser smoke purifier is affected by factors such as the intensity of operation, the concentration of smoke and dust, and even the environmental humidity. By using actual data, it is possible to work out more scientifically when to replace the consumables.

The three key factors affecting toner life.

Hours of daily operation.

The rate of material consumption by a machine that works 10 hours a day is three times that of a machine that only works three hours a day.The committee recommended that the monthly work hours of the equipment be recorded as a basic data point.

The concentration of particulates and the types of particles.

The size of the particles of metal and acrylic dust are different, and metal dust is more likely to clog the filter.If the pressure gauge reading rises rapidly, it may be due to a change in the material.

Environmental temperature and humidity.

In the humid southern climate, the efficiency of activated charcoal drops by 20-30 %, a point which is often overlooked.When the humidity is over 60 %, it is recommended to shorten the replacement cycle by 15 %.

Three steps to finding out how often you should change your underwear.

Step 1: Record initial use data.

When you change the filter, mark the date on your calendar, and record the current pressure difference (for example, 0.8 kPa).They took photos at regular intervals each week to record the changes.

Step 2: Observe the point at which efficiency falls.

When the pressure differential rises to 1.5 times the original value (such as 1.2 kPa), or when the air smells bad, the performance of the filter has clearly declined.Record the total number of days of use.

Step Three: Take 80 % to be safe.

If the test shows that the turning point is on day 90, the actual replacement interval is recommended to be 72 days (90 × 0.8).This can avoid the risks of criticality, and also not waste too much of the residual energy.

Real case: Saving 37 % on consumables.

One metal stamping factory originally changed its air filter every two months, but after recording data it was discovered that it could be used for 78 days.After the adjustment, the company saved NT $ 1,400 per machine per year by reducing the number of changes by two.The key is that on the 60th day they reverse the flow direction of the air gun to blow the filter cotton clean, extending the effective life of the filter by 18 days.

Here are three tips for saving toner.

Clean the pre-filter every month with a weak vacuum cleaner to reduce the burden on the main filter.

• Activated carbon and filter cotton are replaced separately, to avoid waste due to simultaneous replacement.

When purchasing, choose consumables with a window for direct observation of the degree of contamination.
