Jaw crusher is a common crusher equipment, we all know that its working environment, material characteristics have a certain impact on the service life of the equipment. Therefore, the maintenance work in the operation of jaw crusher must be carried out in strict accordance with the operation process, so that its service life can be longer. As the primary crushing equipment of various ores, jaw crusher requires operators to have good operation ability. In the work, how to choose to add grease is a very important operation, which is one of the matters that the operator must pay attention to.
In this paper, Henan Hongxing, the manufacturer of jaw crusher, introduces the relevant knowledge of lubricating oil, which is convenient for more Hongxing users to understand, better understand and operate the jaw crusher, so as to create better benefits for us. The details are as follows:
1. Selection of lubricating oil
Because of the different working environment of jaw crusher, different lubricants need to be selected. In summer, the outdoor temperature is relatively high, so no. 70 mechanical oil can be selected, while in winter, No. 40 oil is suitable for the low outdoor temperature. When the jaw crusher needs continuous work, there is a heating device in winter, which can preheat the lubricating oil. When the ambient temperature is not too high in summer, No. 50 oil can be used as lubricating oil.
2. Lubrication method
Since the bearing and eccentric shaft of large and medium-sized jaw crusher adopt pressure circulation lubrication, when the oil pump fails, the jaw crusher needs to swing power for 15-20min to stop, so it needs to manually press the oil pump to feed oil, so as to keep the bearing lubricated and avoid the accident of burning the bearing.
3. Lubrication time
The lubrication parts of jaw crusher are different, the lubrication requirements are different, and there are differences in terms of time. For example, there is no oil return device for the lubrication of the bearing of the movable jaw suspension shaft and the elbow of the thrust plate of the jaw crusher, so it is necessary to add lubricating grease intermittently. The bearing of the small jaw crusher adopts the way of adding lubricating oil to the oil cup, so the oil can be supplied once every 30-40min. The elbow of thrust plate is lubricated with thick oil, which needs to be lubricated every 3-4h.
4. Temperature of lubrication
Also, we should pay attention to the temperature of the lubricating oil of jaw crusher. In the use of the thin oil system of jaw crusher, the temperature of its return oil shall not exceed 60 degrees. When the temperature is too high, we need to control the oil flow by adjusting the oil valve or adopt the water cooling method to reduce the temperature, only in this way can we ensure its production work.
From the above we can see that there are many lubrication requirements for jaw crusher. No matter the selection of grease, lubrication method, lubrication time, lubrication temperature, etc., we need to control them well, not carelessly. Only when we have a good grasp of the relevant knowledge of the jaw crusher lubricating oil, can we operate the jaw crusher lubricating work better. The operation of jaw crusher is related to the smooth operation of the whole production, so we need to know more about the operation of jaw crusher.
