Replacement of coolant fluid and filtration system and
Summary of maintenance methods
While there are many things that coolant fluid and filtration systems bring to the table, they also require replacement and even maintenance for continued use, so it is important to remember how to do that.
Maintenance of Coolant System
Filtration systems that use diatomaceous earth, cartridges, filters, paper filters, bags, etc. require replacement of filters and other components. Some magnetic separators and centrifugal separators are considered "maintenance-free," but this does not mean that they are completely maintenance-free, as maintenance and inspection are still required.
In addition, grinding sludge separated by centrifugal separation or other means must be periodically disposed of as industrial waste and recycled,We cannot say, "We will not do anything after installation."
Coolant Filtration System Failure Cases and Effects
Maintenance or repair is required if any of the following signs or problems are observed. We recommend that you consult with a professional service provider rather than making your own judgments.
Noise and failure of pumps and motors
If the pump or motor of the coolant filtration system is making abnormal noises, parts may be worn, which can lead to a more serious failure if left unchecked.A possible cause is the bearing.
If the seal is deteriorated or damaged, it must be replaced. In some cases, the noise is caused by a damaged seal. In this case, repair or replacement is the answer.
Clogged filter
If the filter in the coolant filtration system becomes clogged, the coolant flow is restricted and foreign matter and dirt in the coolant cannot be removed. In other words,The effect of the coolant is reduced.In these cases, cleaning is necessary.
If the used filter is removed and the inside of the filter is cleaned to remove foreign matter and dirt, coolant will flow again and filtration will be normal. However, if cleaning does not solve the problem, there may be another cause.
Frequency of Coolant Fluid Replacement
The frequency of coolant replacement is difficult to define in general. Because of the cutting fluid used, the material to be cut, the frequency, and even the temperature and cleaning frequency,This is because it depends on the environment in which the coolant is used.Therefore, it is necessary to check the coolant situation in-house and consider the appropriate replacement frequency.
After installation, concentration and pH control can be performed, and by taking data for several months thereafter, the speed of coolant deterioration can be determined to some extent. It is advisable to determine the frequency of replacement according to the speed of deterioration.
However, do not make decisions based solely on your own company,Recommend also consulting with filtration equipment manufacturers.The following is a list of the most important factors to consider when deciding how often to replace your filtration equipment Decide on the frequency of replacement based on the advice of the filtration equipment manufacturer and your own data.
Procedure and key points for replacing water-soluble coolant fluid
When replacing coolant, the first step is to flush the tank. Even if you replace the coolant with new coolant without flushing the tank, because metal ions and bacteria may remain on the walls and bottom plate inside the tank,These are the causes of deterioration, and deterioration begins.Use neutral detergent/alcohol for tank cleaning to remove dirt.
If a putrid odor or white foreign matter is observed, bacteria are most likely present. In this case, bacteria can be killed by drying the tank in the sun after cleaning. If a coolant system is not used for an extended period of time, there is a risk of bacteria blooms due to stagnant coolant fluid, so it is more efficient to clean the tanks in advance if they will not be used for an extended period of time. In daily coolant management,Appropriate assessment of condition and appropriate measuresIt is important to do the following
In some cases, coolant that is not cleaned and managed will deteriorate in a short period of time, but with maintenance, there may be no problems with either the concentration or pH value after several months of use.
Disposal method of coolant liquid
Although coolant fluid is considered to have little impact on the human body, it is classified as "industrial waste" and must be disposed of properly.
Keep in mind that you may be charged with violating the Waste Disposal and Public Cleansing Law if you discharge waste into the sewage system without proper treatment. Specific treatment methods include detoxification by ion exchange or activated sludge process, but these methods are inefficient to prepare in-house unless you are in an environment where large amounts are consumed daily.
Therefore, it is more cost-effective to ask a waste disposal specialist to handle the waste. As for insoluble coolants, they can be used as fuel by waste oil fuel converting equipment, but some of them are difficult to self-dispose of, so in any caseWe recommend consulting a professional contractor..
