Introduction to the importance of trace lubricants

In the application of micro-lubrication system, the generation of oil mist is very critical. There are many factors that affect the effect of MQL micro-lubrication.

At present, most users do not have a clear understanding of the characteristics of oils used under micro-lubrication conditions. They think that as long as the oil can be used in micro-lubrication processing, this is a wrong understanding. It is very important to correctly select micro-lubricating products.

First of all, mineral oil cannot be used in micro-lubrication processing, mainly because the oil mist particles produced by mineral oil are harmful to the human body, and the particle size generated by mineral oil atomization is large, the lubrication effect is not good, and mineral oil is not suitable for high-speed processing Lubrication in the state.

When the micro-lubrication system is used in cutting, the oil is very important. First of all, the oil must be environmentally friendly and should not cause harm to the health of the operators. At present, foreign countries have clear requirements for the oil used in the metal cutting processing field, and the use of MQL technology in the domestic machining field is still in its infancy. Because the micro-lubricating oil is atomized into 0.5-10 micron oil suspended particles, When selecting trace lubricants, the health and environmental protection characteristics of the oil should be considered first.

On the premise of ensuring that the oil is harmless to human health, it is necessary to consider the lubrication and atomization characteristics of the oil in the cutting process. The first thing to consider is that the oil should have a low viscosity. Only low-viscosity lubricants can be used without heating. It is atomized into ultra-fine suspended particles in the micron range, and can realize long-distance transportation without being affected by the high speed of the machine tool. There are many disadvantages of using mineral oil. Firstly, it is difficult to atomize without heating. Even if heated, the atomization effect of ultra-fine particles cannot be achieved. After the atomization of mineral oil, it is not easy to transport long-distance in the small channel, and it is easy to form oil. Droplets, especially affect the transportation in the main shaft, and easily cause oil accumulation in the pipeline, and the terminal lubrication effect is poor. The reason is that the oil mist that forms large particles is affected by the centrifugal force of the machine tool spindle. Compared with cutting fluid, the consumption of lubricating oil is greatly reduced in cutting under the condition of micro-lubrication, and the consumption per hour is below 50ml/h, which is much lower than the consumption of the traditional heating oil mist lubrication system.

Drive the preferential presetting of the spring frame of the vehicle

The secondary spring system of the original electric locomotive consists of 4 sets of the same ordinary cylindrical compression springs. Its parameters are: spring material diameter d=48mm, maximum working circle diameter D=230mm, effective working circle number n=6.6, free height H0= 528mm, working height H=431mm. The characteristic curve of the spring is approximately straight, with stable stiffness and simple structure. However, the spring stiffness is mainly along the axial direction, and its transverse shear and bending stiffness is very poor, and its anti-resonance ability is poor. After the train speeds up, its snake-like movement and shaking phenomenon intensify. Therefore, it is necessary to improve the spring system of electric locomotives. Improvement of the spring system. The improved spring parameters and characteristics take into account the special position of the secondary spring (between the bogie and the car body) and specific functions (s...
