Q&A on basic knowledge of high temperature chain oil
October 07, 2022
Concept 1: Can the chain be lubricated with ordinary grease? Answer: No Chain Structure First let's take a look at the structure of the chain. The chain usually consists of three parts: chain strands (sleeves), chain rows (chain plates), and chain cores (chain pins). There is only a small gap between each part. If grease is applied, the grease will not penetrate into the parts that need to be lubricated at all, but will only adhere to the surface of the chain. After the grease dries at high temperature, a large amount of residue will be formed, resulting in poor chain operation and residue. It may also cause contamination of the sprayed workpiece.
Concept 2: The lower the viscosity of the oil, the better the penetration, which is the most suitable for chain lubrication? Answer: no why? Because low-viscosity lubricating oil is easy to splash on the chain running at high speed, it cannot adhere to the moving position of the chain and provide proper lubrication, especially for the chain operating at high temperature, the oil will become thinner due to the temperature in the high temperature area, and cannot provide enough oil film Lubricate the chain, causing wear on the chain.
The selection conditions of chain oil should include the following: 1. Chain operating temperature (related to the following items) A. Types of chain oil B. Chain Oil Viscosity & Viscosity Index C. Chain oil residue amount D. Chain oil volatility E. Setting of chain oil pumping position 2. Chain movement speed (related to the following items) A. Chain oil viscosity B. Chain Oil Adhesion C. Anti-wear effect of chain oil D. The setting of chain oil pumping amount 3. Chain load (related to the following items) A. Chain oil viscosity B. Anti-wear effect of chain oil 4. Chain operating environment - humidity, chemical corrosion, dust (related to the following items) A. Types of chain oil B. Chain Oil Viscosity & Viscosity Index 5. Chain use occasions - clean and hygienic (related to the following items) A. Types of chain oil B. Chain Oil Residue Amount C. The setting of the oil amount of chain oil
Seeing this, do you think it is a little troublesome to choose high temperature chain oil? No, no trouble! ! It is very useful to choose fully synthetic high temperature chain oil. Fully synthetic high temperature chain oil has excellent bearing capacity and permeability, can protect good wettability on the metal sliding surface, and provide an oil film with strong adhesion. It has good thermal stability and chemical stability, and can reduce the residue produced by evaporation. Long-lasting performance at high temperatures, excellent wear resistance, and reduced impact on materials. Its special structure can prevent splashing, so it can avoid the contamination of materials during high-speed transportation, and at the same time, the oil can keep the guide rail and chain clean with the consumption of lubricating oil (at the same time, it can take away the dirt), and the operating temperature can reach 250 ℃. What equipment is fully synthetic high temperature chain oil used for? Stenters and dryers for the textile industry Oven chain in paint factory Electronic factory reflow and wave soldering machine chain Heat shrink packaging machine chain, etc.
