Advantages and applications of semi-fluid grease!
December 28, 2021
Semi-fluid grease refers to the general term for greases with a consistency in the range of 000-0. It is made by thickening high-quality Base Oil with organic thickener and adding a variety of additives. Semi-fluid grease is only for "hardness", not for other quality indicators or product types. Semi-fluid grease itself has excellent fluidity. Without any external force, it flows under the action of its own gravity, which overcomes the shortcomings of ordinary grease that is not easy to flow when there is no external force, and solves the problem of easy lubricating The problem of leakage reduces the requirements for complex sealing, maintains the characteristics of good cooling performance and fast heat dissipation, and makes up for the disadvantages of poor cooling effect of traditional grease. At the same time, the use of semi-fluid grease can also save lubricant consumption, simplify equipment maintenance, and extend service life. Performance characteristics of semi-fluid grease: The state of semi-fluid grease is between lubricating oil and plastic grease, and is generally suitable for replacing high-viscosity lubricating oil.
In addition to the advantages of general grease, what other advantages does it have? 1. Good flow performance. The fluidity of semi-fluid grease is much better than that of general grease. It will become thinner as the gear shear speed increases, and it will become thicker as the shear speed decreases. This ensures that the friction pair can maintain a sufficient lubricating oil film at different speeds during operation, thereby prolonging the service life of the gear. 2. Excellent sealing performance Compared with lubricating oil, semi-fluid grease is not easy to be discharged from the oil port in a short time after being added to the gearbox. Therefore, it can effectively prevent the gearbox from leaking lubricating oil and does not pollute the equipment and the environment. 3. The friction coefficient is small. Low power consumption The power loss of the friction pair not only depends on the consistency of the lubricant, but also closely related to the friction of the friction part. The friction coefficient of semi-fluid grease is small, so power consumption will not increase after using semi-fluid grease. 4. Low current consumption. Good starting performance is an important performance of gear transmission, especially when starting smoothly while having a lower starting current is more important. Experiments and comparisons show that the current of using semi-fluid grease is smaller than that of Gear Oil, indicating that semi-fluid grease will not increase power consumption. 5. Good anti-wear performance. The adsorption capacity of semi-fluid grease on the metal surface is stronger than that of lubricating oil. It can form a relatively strong oil film, and can withstand higher working loads. It can effectively avoid dry friction between tooth surfaces. It has a great effect on gears and bearings. Good protection. What equipment will use semi-fluid grease? Semi-fluid grease is widely used in equipment such as pump trucks, concrete mixer trucks, concrete mixing plants, reducers, and pelletizers. Some worm gears also use corresponding worm gear grease products. Gearboxes and continuous casting equipment in steel plants are also used.
