Ten faults and corresponding solutions: ______________________________ Cone crushers have ten common faults and their solutions are here>>> If oil indicator shows no oil, and oil pressure is lower than 0.5 MPa. The reason for that is the temperature of the oil is too low, and the oil switch is turning off; the oil pump not working well. The solution is to heat the oil, turn the oil switch on, and change the oil pump. if there is an oil pressure difference b/w oil pipes and filter. The reason is filter is blocked. the solution is if oil pressure is 0.04mpa then the filter will be cleaned well. if the oil pressure increases, oil temperature also. The Reason there is something wrong with the sleeve of the oil pipe. Solution: check the straight sleeve and cone sleeve after turning off the crusher, and find the problem to solve it. The scavenge oil in the fuel tank is significantly reduced. Reason: the oil leaks from the bottom of the crusher; oil leaks from the flange plate. Solution: turn off the crusher, check the bottom and flange plate, clean the circular groove, and add some oil to the fuel tank. The temperature of the oil discharged from the cooler is beyond 45℃. Reason: there is a lack of cooling water in the cooler; the temperature of cooling water is higher; the cooler is blocked. Solution: add some cooling water to cooler; check whether the hydraulic pressure is too low and try to increase it; check the temperature of cooling water. The oil is mixed with water, which makes the amount of oil increase. Reason: The hydraulic pressure is higher than oil pressure in the cooler. Solution: try to make the hydraulic pressure lower than oil pressure 0.05MPa. The concave is lifted. Reason: the oil pressure is too low in winter; the safety valve fails to work. Solution: preheat the oil; adjust the safety valve; change the oil pump. The water discharged from the water seal is mixed with oil. Reason: the circular groove in the spherical bearing is blocked. Solution: Clean the circular groove and add oil to the fuel tank. There is crackle when crushing stones. Reason: the mantle or the concave of cone crusher is loose. Solution: the bolts should be fixed frequently; check the U-type bolts of the fixed liner. The current is too high. Reason: there are too many rocks in the chamber; poor lubrication; the bearing or the spherical bearing is broken. Solution: adjust the feeding; strengthen the lubrication; change the bearings. Through the study of this article, you must have a deeper understanding of the operation and maintenance of the cone crusher. In the case of the above-mentioned failure of the crusher, the problem is analyzed and solved by referring to the method given in this article. If the fault cannot be eliminated, welcome to consult the HXJQ Machinery, we will be happy to serve you with the fastest speed and provide you with the most effective solutions.
