Cone Crusher Common Fault
Common malfunctions of Cone Crusher
Fault 1: The oil pressure in the oil pipe before and after the filter is different
Cause of the malfunction: the filter is clogged
Trouble-shooting: When the oil pressure difference exceeds 0.04MPa, the filter must be cleaned. First, let the oil not pass through the ground filter, then remove the filter to clean, so that the oil is directly supplied to the crusher, no more than 2-3h.
Fault 2: There is no oil flow in the oil flow indicator, but the oil pressure is lower than 0.5MPa
The cause of the malfunction:
1.The oil temperature is low;
2.The oil switch is not opened well;
3.The oil pump is not easy to use;
2.Turn the switch on;
3.Stop the crusher and replace the oil pump;
Fault 3: The oil return in the fuel tank is reduced, and the oil level is significantly reduced.
The cause of the failure:
1.The bottom cover of the crusher leaks oil;
2.The oil leakage of the bearing shell flange;
3.The spherical bearing seat ring is blocked or the oil is too much, and the oil leaks from the dustproof device.
Troubleshooting method: 1, 2 stop, find out the cause to eliminate, then add oil to the fuel tank; 3 stop, clean the oil ring groove, adjust the oil supply, and add oil to the fuel tank.
Fault 4: oil temperature exceeds 55°C, but the oil pressure does not rise
The cause of the malfunction: There is something wrong with the eccentric bushing;
Troubleshooting: Stop checking the straight bushing and the cone bushing to find out the cause of the fault.
Fault 5: The oil temperature rises while the oil pressure rises
Cause: The oil pipe inside the tubing or crusher is blocked.
Troubleshooting method: stop to find the blockage and clear
Fault 6: The oil temperature from the cooler exceeds 45 °C
The cause of the failure:
1. no cooling water;
2. the cooling water temperature is high;
3. the cooler is blocked.
Troubleshooting method: give cooling water; check if the water pressure is too low, increase the pressure as much as possible, check the cooling water temperature; clean the cooler
Fault 7: There is water in the oil and the oil in the tank increases.
Cause: The water pressure in the cooler is higher than the oil pressure
(1) Pay attention to prevent excessive oil pressure. If the oil pressure exceeds 2 kg/cm2, it will cause injury.
of Cone Crusher
(2) During the operation check, the coupling guard should be ensured to be intact, and the screw of the coupling should be prevented from falling off and hurting; if the pressure is too large, the joints will be stretched and the oil ll splash and hurt people.
