Jaw Crusher common troubleshooting methods(2)

Spring fracture
Reasons:
Transfer of small nesting population, the non-relaxed springs
Troubleshooting:
Replacement spring

Block off adjustment
Reasons:
1) elbow board, elbow pads to the procurement board or system, do not meet design requirements of OEMs
2) to adjust the fixed bolts loosening Block
3) Block adjustment casting serious welding defects or defects
Troubleshooting:
1) the replacement and adjustment of seat assembly to replace the original OEM elbow board, elbow pad plate
2) the replacement of seat adjustment and seat adjustment bolt will be tight
3) the replacement of seat adjustment

Eccentric shaft bending or breaking
Reasons:
1) lifting the host occurred during the rollover, so that unilateral eccentric shaft bending force
2) has been broken for more than material hardness product specification requirements
3) ultra-long-term negative operating console
4) sub-standard toggle plate, non-broken material into the cavity when broken off from the protective effect of
5) eccentric shaft improper heat treatment, stress concentration, resulting in a short period of fracture
Troubleshooting:
1) replacement of the eccentric shaft, lifting the right host
2) replacement of the eccentric shaft, the compressive strength of materials by crushing, select suitable crusher
3) replacement of the eccentric shaft, transfer or replacement of the load operation is suited to crusher
4) replacement of the eccentric shaft, non-use of design standards do not match the elbow plate, plate elbow pad
5) replacement of the eccentric shaft, the use of heat treatment of the eccentric axis of qualified

Moving jaw fracture
Reasons:
1) left-intensive casting serious shortcomings, such as stomatal
2) the use of unqualified elbow plate, plate elbow pad, crusher in a strong shock from the bracket did not break the protection of
3) moving jaw displacement occurred in the rack, one rack at the bottom side of retaining plate collision
4) The spring tension rod immediately after the expiration of the timely replacement of yet
5) the provisions of nesting population is less than the limit
6) The feed location is not in favor of a client or under the hopper angle is too steep, so that the direct impact of material moving jaw head.
Troubleshooting:
1) the replacement of fixed jaw
2) replacement of fixed jaw. At the same time, replaced the original OEM production elbow plate, plate elbow pad
3) replacement of fixed jaw. At the same time, the right eccentric shaft assembly, bearings, bushings and dynamic set tight jaw, the replacement of damaged parts
4) the replacement of fixed jaw. At the same time, the replacement of the spring rod
5) the replacement of fixed jaw. At the same time as required to adjust nesting population
6) the replacement of fixed jaw. At the same time by doing into the hopper to ensure that the material under the uniform, smooth, and the second from the middle to the edge points.

Rack bearing or moving the jaw with excessive temperature rise
Reasons:
1) Bearing off too much oil or oil-injected
2) plug the hole, not into the oil increases
3) Flying Wheel block position weight deviation, beating rack
4) set tight bushing axial movement occurred
5) bearing wear or damage such as Cage
6) Non-bearing temperature rise, but the move set of the jaw and the end caps sealed heat or friction bearing rack covered with double inlay with the rotation axis, friction heat
Troubleshooting:
1) Manual provides refueling time quantitative
2) clean-up hole, plug oil complex
3) The transfer is to fly round slot position with weights;
4) demolition rack bearing caps, locking firmly fixed bushing and flywheel removed or tank round, the replacement of a new set of tight bushing
5) the replacement of bearings
6) Cover and seal replacement kits, or heat release rack bearing on one end of the bearing caps, and fuses together with the inlay cover bearing pressure tank into the rack, and then set on the bearing cap, the elimination of rotating cover inlay.
