How to disassemble the jaw crusher?
It is understood that after long-term use, the jaw crusher needs to be regularly repaired and maintained to extend the service life of the equipment, and disassembly work is required during the maintenance process. The main contents of the jaw crusher disassembly are as follows:
1. For the jaw crusher with an integral connecting rod, to remove the thrust plate, you must first unscrew the baffle bolts, cut off the dry oil lubricating oil pipe, and hang the thrust plate on the crane lifting hook or other lifting equipment, and then loosen the spring at one end of the horizontal connecting rod, pull the movable jaw to the fixed jaw direction, and remove the thrust plate.
After visiting Kefan Heavy Industry, we learned that if the rear thrust plate is to be removed, the connecting rod should be pulled apart together with the front thrust plate and the movable jaw to remove the rear thrust plate.
2. After the thrust plate is removed, cut off the thin lubricating oil pipe and cooling water pipe, support it with a bracket under the connecting rod, and then remove the connecting rod cover before lifting the connecting rod.
3. The main shaft of the jaw crusher should be removed together with the pulley and flywheel. Move the motor (with the belt) as close to the jaw crusher as possible along the slide rail and remove the V-belt. Then lift the shaft with a crane.
4. In order to disassemble the movable jaw, you must first cut off the dry oil lubricating oil pipe, remove the pull rod, remove the bearing cover, and then use a crane or other lifting equipment to pull out the movable jaw. The above four points are the key points of jaw crusher disassembly. However, before the disassembly of the jaw crusher begins, first ensure that the power is off, and the upper and lower equipment of the production line are stopped before the disassembly work can be carried out. The following briefly introduces some simple knowledge of jaw crusher maintenance.
1. Regularly shut down the jaw crusher to check the machine. Any stone crushing equipment should be turned on and off at the same time. Regularly shut down the jaw crusher to check the wear inside the machine, such as the wear degree of the center feed pipe, cone cap, upper and lower flow channel linings of the impeller, circumferential guard plates, and wear-resistant blocks. Replace the parts with more serious wear immediately to repair these parts. At the same time, pay attention to the weight, model and size of the replacement parts. They must be replaced according to the original part parameters.
2. Regularly reduce the production of the jaw crusher conveyor belt. The jaw crusher conveyor belt is indispensable in the stone production line. The machine is driven by the conveyor belt. Regularly adjust the tightness of the conveyor belt to ensure that the conveyor belt is evenly stressed. When driven by dual motors, the triangle belts on both sides should be selected in groups so that the length of each group is as consistent as possible.
If the drive belt is found to be too worn, please replace it immediately.
3. Lubrication of mechanical parts The jaw crusher uses Mobil automotive grease or 3# lithium grease. Add appropriate amount of grease every 400 working hours. Open the main shaft assembly to clean the bearings after 2000 working hours. Generally, replace new bearings after 7200 working hours.
In addition, in order to ensure the normal operation of the jaw crusher, in addition to the correct operation of the jaw crusher, planned maintenance must be carried out, including daily maintenance inspection, minor repairs, medium repairs and major repairs.
(1) Minor repair: The main contents include checking and repairing the jaw crusher adjustment device, high-speed discharge port clearance, turning or replacing the worn liner.
Inspect the transmission part, lubrication system and replace lubricating oil.
The cycle of minor repairs is about 1-3 months.
(2) Medium repair: In addition to all the work of minor repairs, it also includes replacing the thrust plate, liner, checking and repairing the bearing, etc.
The cycle of medium repairs is generally about 1-2 years.
(3) Overhaul: In addition to all the work of the overhaul, it also includes replacing or turning the eccentric shaft and the movable jaw shaft, casting the babbitt alloy on the upper part of the connecting rod head, and replacing or repairing various wear parts.
The overhaul cycle of the jaw crusher is generally about 5 years.
