Most of the various lubricants commonly used in printing plants are petroleum-derived mineral oils with additives. The thickening of the lubricating oil is distinguished by the viscosity, the greater the viscosity, the thicker the oil.
Greases are made from mineral oil, thickeners and additives. The softness and hardness of fat are differentiated by penetration. The greater the penetration, the softer the fat.
To fuel the equipment, it must comply with the specifications and specifications specified in the operating manual (or instruction manual). Otherwise, it is easy to have problems.
A factory in the early use of the 4-color machine in Heidelberg, only know the difference in the viscosity of lubricating oil, do not know that there are a variety of lubricants, into the ISO100 engine oil. Some days later, the automatic detection of the machine showed a red light and the machine could no longer start. When the tank is opened, the lubricating oil is no longer a brown transparent liquid but becomes a porridge. There are many yellow pieces mixed in it, like oatmeal porridge.
What is the reason? The original Heidelberg 4-color machine transmission gears have high manufacturing precision, especially in the early stage of use, the flank clearance is very small. Ordinary oil can not withstand the rolling of the gear, the gear movement and heating up accelerates the oxidation of the oil. The oxidized oil forms a hard rake and is crushed into many pieces by gears. The deteriorated oil was released, the tank was cleaned, the oil path was dredged, and the ISO100 extreme pressure gear oil was injected as required. The machine had never experienced any lubrication accidents since then.
Extreme pressure gears are based on mineral lubricating oils with suitable viscosity. They are formulated by adding rust inhibitors, antioxidants, anti-foam and extreme pressure anti-wear additives. In the high temperature state, it can form a relatively strong compound film with the metal surface. It has a lower melting point than the metal. When the metal surface heats up due to friction, the compound film melts into a smooth surface, which can reduce the temperature and reduce the friction. Prevent scratches, seizures, or welding by metal friction.
Use extreme pressure gear oil, but also pay attention to different brands of oil can not be mixed together. Because there are two kinds of extreme pressure additives, one is sulfur phosphorus type, and the other is lead type. The two are mixed together to undergo chemical changes that degrade the oil. Different brands of oil cannot be used together. Because there are two kinds of extreme pressure additives, one is sulfur phosphorus type, and the other lead consumption. These two kinds of mixing in one axious chemical change, so that the oil deterioration. Different brands of oil may have different extreme pressure additives. Even if it is the same brand, we must also look at its packaging words, the same is Pegasus, Mobile Compound is lead type, Mobilgear is sulfur phosphor type.
The equipment used by the printing plant for extreme pressure gear oils are: KBA- Rapida 104CX (with Mobilgear 627, viscosity grade ISO100), KOLBUS splice gearbox (with Mobilgear 630, grade ISO220) martini rubber Book machine 3006 (with Mobilgear 626, class ISO68), Heidelberg Herries motor gearbox (with Mobilgear 630, class ISO220).
Air compressor oils are also more stringent. If the oil is used improperly, the oil in the high temperature, high pressure, high frequency cylinder is easy to oxidation, carbon deposition, not only does not achieve lubricating effect, accelerate the cylinder and piston wear. The exhaust valve is more dangerous to deposit carbon. Coke will cause the exhaust valve to close tightly, and the discharged compressed air may return to the cylinder when inhaled. Compressed air frequently enters and exits the exhaust port, making it easy to warm up the valve. If the amount of fuel is too large, the oil vapor mixture in the trachea will be detonated.
Compressor oil is a deep refining of petroleum, adding antioxidants, metal deactivators, rust inhibitors, clean dispersants, anti-wear agents and defoamers, with good oxidation stability, corrosion resistance, anti-foam Sex, viscosity, low volatility, and carbon deposition tend to provide good lubrication and sealing to cylinders and pistons. It cannot be replaced by any other oil.
There are various kinds of equipment used in printing plants, and different equipments have different structures and characteristics. Therefore, the properties and requirements of lubricants vary from device to device. For the purpose of making the equipment well lubricated, achieving the goal of reducing wear, reducing energy consumption, and prolonging the service life, it is extremely important to properly select the type and specification of the lubricant and properly use the lubricant.
