(1) Cleaning of hydraulic cone crusher
Cleaning the appearance of the diesel engine, chassis and working devices of the cone crusher construction machinery can play a role in descaling and decontamination. During the cleaning process, damage to various devices and components and oil leakage parts can also be found, so as to prepare for the next maintenance. preliminary work. It is strictly forbidden to use a high-pressure and high-temperature water gun to wash the parts with high waterproof requirements, especially the electrical parts, so as to avoid damage.
(2) The oil pressure in the oil pipes before and after the filter is different, how to deal with it?
Cause of failure: filter clogged
Troubleshooting: When the oil pressure difference exceeds 0.04MPa, the filter must be cleaned, first make the oil not pass through the ground filter, and then remove the filter for cleaning, so as to directly supply oil to the crusher, no more than 2-3h

(3) There is no oil flow in the oil flow indicator, but the oil pressure is lower than 0.5MPa, how to solve it?
Reasons for failure: 1. Low oil temperature; 2. Oil switch is not turned on properly; 3. Oil pump is not easy to use;
Troubleshooting methods: 1. Oil heating; 2. Turn on the switch; 3. Stop the crusher and replace the oil pump;

(4) The amount of oil returned in the fuel tank is reduced, and the oil level is significantly reduced. What should I do?
Causes of failure: 1. Oil leakage from the bottom cover of the crusher; 2. Oil leakage from the flange of the transmission bearing shell; 3. The groove of the spherical bearing seat ring is blocked or too much oil is supplied, and the oil leaks from the dust-proof device
Troubleshooting methods: 1. 2. Stop the machine, find out the cause and eliminate it, and then add oil to the fuel tank; 2. Stop the machine, clean the oil return ring groove, adjust the amount of oil supplied, and add oil to the fuel tank

(5) The oil temperature exceeds 55℃, but the oil pressure does not rise. What is the reason?
Cause of failure: There is something wrong with the eccentric shaft sleeve;
Troubleshooting method: stop the machine to check the straight bushing and tapered bushing, find out the cause of the fault and clear it;

(6) When the oil pressure rises, the oil temperature also rises, how to solve it?
Cause of failure: The oil pipe or the oil circuit inside the crusher is blocked
Troubleshooting method: stop the machine to find the blockage and clear it

(7) The temperature of the oil coming out of the cooler exceeds 45℃?
Reasons for failure: 1. No cooling water; 2. High temperature of cooling water; 3. Blockage of cooler
Troubleshooting method: supply cooling water; check whether the water pressure is too low, increase the pressure as much as possible, check the cooling water temperature; clean the cooler

(8) What is the reason for the moving cone being lifted?
Causes of failure: 1. The oil temperature is too low in winter, which makes the oil supply pressure too large; 2. The safety valve fails, and the oil supply pressure is too high; 3. The oil pump used is too powerful
Troubleshooting methods: 1. Preheat the lubricating oil; 2. Adjust the safety valve; 3. Replace the oil pump

(9) What should I do if the water seal does not enter the water?
Cause of failure: There may be a problem inside the crusher
Troubleshooting method: stop and check the inside of the crusher, find out the cause and eliminate it

(10) The crusher vibrates, and the spring loses its elasticity quickly
Reasons for failure: 1. Uneven or excessive feeding; 2. Too much fine ore in feeding; 3. Too much fine ore in feeding; 4. Insufficient spring tension;
Troubleshooting method: 1, 2, 3 to eliminate the reasons indicated; 4 to adjust the height according to the spring, but not to exceed the specified value.

(11) There is a violent impact sound, the support ring jumps up, and then the crusher works normally again
Cause of failure: The material that cannot be broken enters the crushing cavity and is then discharged
Troubleshooting Methods: Failure

(12) “Crackling” sound when crushing ore
Causes of failure: 1. The lining of the crushing motor cone is loose; 2. The lining of the fixed cone is loose
Troubleshooting methods: 1. Always check the nuts that hold the lining plate. If the zinc alloy is loose, it should be poured again; 2. Check the U-shaped bolts that fix the lining plate. If the zinc alloy is loose, it should be poured again.

(13) The crusher vibrates violently, and the moving cone rotates quickly
Causes of failure: the main shaft is stuck in the cone bushing; lack of oil or oil is not clean; the spherical tile is worn, or other reasons cause the moving cone to sink, and the clearance between the main shaft and the cone bushing is too small
Troubleshooting method: stop inspection, find out the cause and eliminate it

(14) After the hoarse “crack” sound, the drive shaft or pulley turns and the moving cone does not move
Causes of failure: 1. The main shaft is broken; 2. The bevel gear key is damaged; 3. The pulley key is damaged
Troubleshooting method: stop inspection, find out the damaged part, and replace the damaged part

(15) The current is too high
Causes of failure: 1. Too much ore feeding; 2. Poor lubrication; 3. Damage to the bearing or spherical bearing; 4. The bearing contact surface is seriously insufficient; 5. The large bevel gear part is rubbing against the lower part of the spherical bearing seat;
Troubleshooting methods: 1. Adjust the ore feeding; 2. Strengthen the lubrication; 3. Replace the bearing; 4. Re-scrape or replace; 5. Add a pad to the lower part of the spherical bearing seat;
