First, there is no proper use of lubricants according to the season. Different viscosity grades of oil should be used depending on the weather conditions. For example, using low-viscosity oil in summer can lead to bearing damage due to insufficient oil film formation, which may result in diesel engine knocking or even tile burning.
Second, dirty or contaminated oil can cause serious issues. If unclean oil is added to the engine, it can clog the oil passages, leading to poor lubrication and potential bearing failure. Regular oil changes and using high-quality oil are essential for maintaining engine health.
Third, improper oil levels can also lead to problems. Adding too much oil can cause the engine to burn oil, resulting in carbon buildup and increased emissions. On the other hand, too little oil can cause the crankshaft or bearings to overheat and eventually seize. It's important to check the dipstick regularly and keep the oil level between the upper and lower marks.
Fourth, ignoring the oil pressure gauge is a common mistake. Under normal operation, the oil pressure should be between 0.15 to 0.25 MPa, and at idle, it shouldn't drop below 0.5 MPa. Many operators neglect to monitor this critical parameter, which can lead to undetected issues that might result in costly repairs.
Fifth, incorrect clearance between the bearing and the shaft can cause severe damage. If the clearance is too small, oil may not flow properly, preventing the formation of an adequate oil film. If the clearance is too large, oil leakage increases, and the oil film becomes unstable. Proper installation and regular maintenance are necessary to ensure the clearance remains within the manufacturer’s specifications.
Lastly, long-term overload operation can significantly increase the risk of bearing failure. Prolonged heavy loads raise engine temperatures, reduce engine speed, and decrease the oil pump’s efficiency. High temperatures also lower the oil’s viscosity, making it less effective at protecting the bearings. This combination of factors makes the engine more prone to tile burning and mechanical failure.
By following these guidelines and being attentive to maintenance practices, you can extend the life of your engine and avoid many common issues related to lubrication and bearing wear.
Air Purifier
Dynamic disinfection is a process of disinfection and cleaning of air and surfaces in indoor Spaces. A
new method of safe disinfection that does not cause harm or interference to people and the environment on
site.The charged particles and active oxygen components produced by the low-temperature plasma in the
equipment play a major role in the process of killing bacteria and viruses, and have the effect of
broad-spectrum sterilization. It can not only inactivate aerosol plankton in the air and bacteria
and viruses on the surface of object but also effectively decompose formaldehyde and volatile organic
compounds, degrade all kinds of bad smell and purify it Air environment.A small amount of high purity
zone.
Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to decoration pollution that can absorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc. , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.
There are many different technologies and media in air purifiers that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Carbon core filter technology, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time.
