Buying grease: Avoid the traps and master the tricks
In the daily maintenance and operation of mechanical equipment, the selection and use of grease is crucial. However, there are many kinds of greases on the market, and the quality is uneven, so how to avoid the trap and choose the right grease has become the focus of many users. This article will reveal the pitfalls of buying grease and provide you with some practical selection tips.
First, understand the basic knowledge of grease
Before buying grease, you must first understand the basic knowledge of grease. Grease is mainly composed of three parts: Base Oil, thickener and additive, of which base oil is the main component of grease, thickener determines the consistency and stability of grease, and additive is used to improve the performance of grease. Understanding these basic knowledge will help you better choose and use greases.
2. Identify market traps
1. Price trap: The quality of cheap grease is often difficult to guarantee. In order to pursue profits, some bad businesses may use inferior raw materials to produce grease, resulting in unstable product performance and may even cause damage to equipment. Therefore, when buying grease, do not covet cheap, should choose cost-effective products.
2. Brand trap: The product quality of well-known brands is often more guaranteed, but there are also some bad merchants who will impersonate well-known brands to sell inferior products. Therefore, when buying grease, it is necessary to carefully identify the authenticity of the product and choose regular channels to buy.
3. Specification trap: Different equipment needs to use different specifications of grease. If you choose the wrong specification, it may lead to poor lubrication or serious failure. Therefore, when buying grease, be sure to choose the right specification model according to the requirements of the equipment.
Three, master the choice of skills
1. Consider the working conditions: different working conditions have different performance requirements for grease. For example, in a high temperature environment, it is necessary to choose a high temperature resistant grease; Under heavy load conditions, it is necessary to choose a grease with strong bearing capacity. Therefore, when choosing grease, it is necessary to choose according to the working conditions of the equipment.
2. Focus on product quality: Product quality is one of the key factors in the selection of grease. High quality grease has good stability, oxidation resistance and corrosion resistance to ensure the normal operation of equipment. Therefore, when buying grease, it is necessary to choose a product of reliable quality.
3. Understand product performance: When choosing grease, it is necessary to understand the performance indicators of the product, such as cone penetration, drop point, extreme pressure, etc. These performance indicators can reflect the lubrication performance, high temperature resistance and bearing capacity of the grease. By comparing the performance indicators of different products, you can choose a more suitable grease.
Iv. Summary
When buying grease, avoid the price trap, brand trap and specification trap. By understanding the basic knowledge of grease, identifying market traps, and mastering the selection skills, you can choose the right grease products to ensure the normal operation of the equipment. At the same time, in the process of use, it is also necessary to pay attention to the correct use and storage methods to extend the service life of the grease and the running time of the equipment.
