Reasons for bearing damage of hammer crusher:
The bearings used in the hammer crusher produced by our company are produced by large manufacturers with good market reputation, and can be used for a long time if properly maintained in the actual production process. However, in the actual production process, there are customers in the production of not long, on the phone to Shandong Sanxiang Heavy industry machinery after-sales service hotline to ask the bearing model, it should not be.
What are the causes of abnormal damage to the bearing of the hammer crusher produced by our company?
One, not beating the butter on time. Generally, after a period of production, the machine must beat the butter in time, but sometimes due to the negligence of the staff, it is forgotten. In this case, if the hammer crusher is started, due to the lack of lubricating oil in the bearing, it is easy to hold, and the ordinary method can not be removed. I have seen several times in the customer's production site, are hit with a sledgehammer, coupled with electric welding cut bit by bit ground down, it is easy to hurt the big shaft. In this case, Shandong Sanxiang Heavy machinery is generally recommended to remove the broken rotor to the factory for maintenance.
Second, the crusher cavity into the large iron block and other debris, hard bearing don't break. This situation is also very serious, and the production site is generally not repairable. The reason is that the large shaft may be deformed and distorted, if it is not completely solved and corrected, the new bearing is installed back, which is easy to damage the new bearing due to the eccentric force generated by the rotation of the rotor.
Third, the machine is not engaged in production activities for a long time, during which there is no effective maintenance of the machine, resulting in a lack of lubricating oil in the bearing, which is also prone to problems. The machine has been idle for too long, and when reproducing, the original oil needs to be discharged and replaced with a new one.
Fourth, in the daily production process, pay attention to check the tightness of the pulley, screw loose to quickly screw, otherwise it is easy to damage the bearing due to the eccentric force generated by the high-speed rotation of the pulley. I have personally seen the phenomenon of the pulley flying off the customer's production site, fortunately did not hit people.
Fifth, it cannot be denied that there are quality problems in individual bearings of the new machine, and bearing damage occurs in a short time. In the contract, it is clearly stipulated that the wearing parts damaged by non-human factors will wear no more than one third, and the shelf life is one year. Bearings with quality problems within one year will be replaced by the company free of charge.
Production safety is no small matter, I have summarized so many reasons for bearing damage, if you have other findings, welcome to call Shandong Sanxiang Heavy Industry machinery after-sales hotline to discuss, thank you!
