Impact Crusher Lubrication Effect

Impact Crusher Lubrication Effect

The maintenance operation of the impact crusher in production, which includes regular lubrication, is to reduce the wear in production, but in many cases, the lubrication effect is not ideal, then what restricts the lubrication effect of the machine What?

In the crushing process of the material, the internal parts of the impact crusher are gradually worn due to mutual force and friction, which makes the life of the crusher gradually reduced, which is extremely disadvantageous for the production cost. And it will affect the efficiency, so in order to prevent this phenomenon, we usually regularly lubricate the machine during production. Choosing the right type of lubricant can reduce the wear and tear in the production and ensure its service life.

Regular lubrication can help reduce the phenomenon of wear, mainly depending on the effect of lubrication. If the lubrication effect is good, then the expected demand can be achieved. If the lubrication effect is not good, then the phenomenon of increased wear can not be prevented. In terms of the production process of the crusher, what restricts the lubrication effect of the machine?

1. Load pressure: When the equipment is working, the crushed ore is squeezed through the parts and transmitted to the sliding friction pairs to generate pressure, which increases the load pressure. The heat generated by the friction pair increases in proportion to the load, and the heat increases. The temperature rises, so that the lubrication effect is affected;

2. Temperature change: The lubricating oil of the impact crusher will change with the change of temperature. The temperature will be low, the lubricating oil will become thicker, and the high temperature lubricating oil will be easily thinned. For example, the high temperature weather in summer is suitable for the lubrication with high consistency. Oil, cold weather in winter requires a weakly viscous lubricating oil. If the temperature of the lubricating oil does not meet the weather conditions at the time, the lubricating effect will also decrease.

3. High and low speed: When the impact crusher is working, the faster the rotation speed, the harder it is to squeeze into the lubricating oil between the rollers, resulting in poor lubrication. The heat generated by the friction pair is proportional to the rotational speed, and the rotational speed is too high. Heat will affect the lubrication of the crusher;

4. Impact load: The engine of the impact crusher will generate the law power. At this time, the crushing equipment needs a thick lubricating oil containing extrusion additives to prevent the oil film from rupturing and causing friction. If the oil film breaks, the friction between different parts cannot be Decrease

5. Oil quantity: The oil quantity of the impact crusher is provided by the gear oil pump. Since the gear pump works by the change of the sealing volume, as the wear quantity increases, the oil simmering capacity decreases, and the internal oil discharge increases. Insufficient supply of normal oil flow required inside the main engine, affecting the lubrication effect;

6. Contact area of friction pair: the actual contact area of ??the friction pair increases, the heat generated per unit area is relatively reduced, and the contact area of the friction pair is less, which will cause high temperature, which will seriously deteriorate the local lubrication, thus affecting the lubrication effect;

The article mainly introduces the constraints of the lubrication effect in the production of impact crusher. The above mainly introduces six factors, these different factors have an important impact on the lubrication of the machine, and how the lubrication effect is on the production process. And the life of the machine has a great impact, so we must ensure that the lubrication in the work is good.
