FAQ
It is generally not recommended to mix greases made with different thickeners. The following are soap-based grease can be mixed, such as calcium-based grease, and sodium-based grease, or lithium-based grease and composite lithium-based grease, etc., can be mixed with each other, generally does not lead to too much change in performance, and does not affect the use.
However, extreme pressure type grease contains various active components, when mixing with each other, additives will interfere with each other, resulting in deterioration of colloidal stability or mechanical stability of the grease, which will affect its performance. Before mixing different types of grease with each other, do the performance measurement to confirm that there is no obvious effect before use.
Compressor oil change period, with the compressor construction form, media, operating conditions, lubricating oil, and lubricating oil quality is different, in the process of operation, specify how much time for an oil change is impractical. Oil change time can only be decided according to the prevailing conditions. Samples should be taken periodically to observe the color and cleanliness of the oil, and to analyze the viscosity, acid value, and physical and chemical properties of the oil at regular intervals.
One of the following situations should be considered for oil change:
the oil color appears green, or the color number deepens 4 levels.
Acid value exceeds 0.5mg/g.
Viscosity change more than 15%.
-Poor fluidity, resulting in cold start and start-up wear.
-Poor heat dissipation, shortening the life of the oil.
Solution:
· Recommend lubricants that meet the quality requirements specified by the engine manufacturer to the customers.
· Choose high-quality base oils, high-performance additives, and appropriate formulations.
· In special circumstances, provide products with a greater margin of quality or higher quality grades.
Q:The Importance of Low Temperature Gear Oils
Challenges in cold environments
In cold environments, mechanical equipment faces a number of challenges, such as increased viscosity and reduced fluidity of the lubricant. These issues can lead to difficulty starting equipment, increased friction, and even damage to gears and bearings, which in turn can affect the normal operation of the equipment.
Advantages of cryogenic gear oils
Cryogenic gear oils have excellent low-temperature fluidity and viscosity temperature dependence, and are able to maintain fluidity in extremely cold environments to ensure smooth equipment startup. In addition, it also has good anti-oxidation performance and anti-wear performance, which can effectively reduce mechanical wear and prolong the service life of the equipment.
Q:Performance Characteristics of Low Temperature Gear Oil
Low temperature fluidity
Low temperature gear oil can flow quickly in low temperature environment, to ensure that the lubricant can reach the key parts of the equipment in time, to reduce the friction and wear during startup.
Antioxidant performance
Since cryogenic gear oils are usually used under extreme conditions, their antioxidant performance is very important. This performance can effectively prevent the oil from precipitation due to oxidization during long time use, and maintain the cleanliness and stability of the oil.
Anti-wear performance
The anti-wear performance of low-temperature gear oil can reduce the friction between mechanical parts and slow down the wear of the parts, thus prolonging the service life of the equipment.
Q:Areas of application
Transportation in cold climates
For vehicles that operate in cold climates, such as airplanes, trains, and automobiles, the use of cryogenic gear oils ensures that the engine and drive train can operate efficiently even in extremely cold environments.
Polar exploration and mining
During exploration and mining operations in polar regions, machinery and equipment often need to operate in extremely low temperatures, and the use of cryogenic gear oils can ensure the normal operation of the equipment.
Q:How harmful is water in hydraulic oil?
First, the way water into the hydraulic system:
Mechanical failure, such as poor sealing, cooling coil leakage so that water into the oil.
In the hot and humid climate, the oil tank breathing and brought in.
Working environment humidity, rain, snow, ice melt water pollution.
Second, the harm of water on the hydraulic system:
Can react with the hydraulic oil, the formation of acids, gums and sludge, water can also precipitate additives in the oil; the main effect of water is to reduce lubrication, dissolved in hydraulic oil in trace amounts of water can accelerate the wear of high-stress components, only by the water (100-400) × 10-6 mineral oil rolling bearing fatigue life studies have shown that the bearing life is reduced by 30% -70%. Water can cause sticking of the control valve, in the pump inlet or other low-pressure parts to produce vapor damage, corrosion, rust and corrosion of metal.
Third, the solution:
Strengthen the monitoring of the water content in the oil, outdoor use of hydraulic equipment, it is best to use weatherproof tents, strengthen the system sealing measures, waterproof entry. Tank breathing holes installed dryer, the conditions of the system can be installed "super-absorption type" filter drier.
Q:What is anti-stuck grease?
Anti-stuck grease, as the name suggests, is a kind of grease that can prevent mechanical equipment parts from sticking and rusting. It is usually composed of base oils, thickeners and various additives, and has excellent lubrication properties and corrosion resistance.
Why do I need stickproof grease?
Mechanical equipment in the operation process, due to friction, vibration and harsh environment and other factors, it is easy to lead to stagnation between parts, rust. This will not only affect the normal operation of the equipment, but also may cause serious damage. The role of anti-stuck grease is to effectively reduce the friction between parts by forming a protective film, extend the service life of equipment, and improve work efficiency.
Characteristics of anti-stuck grease:
Excellent lubrication performance: Anti-stuck greases contain high-quality base oils that maintain excellent lubrication under a variety of operating conditions.
Corrosion resistance: Anti-corrosion additives are added to effectively prevent the equipment from rusting in a humid environment and maintain the stable performance of the equipment.
Widely applicable: anti-jam grease is suitable for various industrial fields, such as machinery manufacturing, automobile manufacturing, aerospace, etc., to provide comprehensive protection for different equipment.
Temperature stability: It has good temperature stability and can maintain stable lubrication performance in high or low temperature environment.
How to correctly select and use anti-stuck grease?
Select the right type according to the working conditions: Different working environments and requirements require the selection of different types of anti-stuck greases to ensure that they can perform best under specific conditions.
Regular inspection and replacement: check the lubrication parts of the equipment regularly to ensure that the anti-card grease is not lost or deteriorated, and replace it in time to ensure the normal operation of the equipment.
Correct application: When applying anti-jam grease, ensure that it is evenly applied, not too much or too little, so as not to affect the lubrication effect.
Follow manufacturer's recommendations: Each type of equipment has manufacturer's recommendations and requirements when using stickproof greases, and it is important to follow these recommendations to ensure the proper operation of the equipment.
