Crusher equipment is the brunt equipment that mine extracts, basically undertake in the light of the stone with differ size broken, crusher equipment basically has gnathic type crusher, strike back crusher of type of type crusher, concussion type crusher, Shuang Gun crusher, hammer and conic type crusher. Because crusher work environment is harsh and bear intensity of pressure is spent big, the user is necessary to master crusher adroitly of common breakdown eliminate a method, here introduces the machine of 3 big trouble with common crusher to eliminate a method for everybody.
Crusher 3 big trouble: Bearing corrective maintenance, runner shaft corrective maintenance, and calm, rotor core corrective maintenance. We are opposite below point of 3 big corrective maintenance undertakes an analysis:
One, component of tatty of bearing corrective maintenance.
Runner shaft props up roll through bearing, the part with oneself since the so heaviest load, it is easy tatty component.
① breakdown is checked
The examination in moving; When scroll bearing is short of oil, can hear the voice of ” of “ roll roll; If hear the voice of ” of discontinuous “ stalk stalk, the likelihood is burst of bearing steel group. Mix inside bearing sandy soil waits sundry or bearing spare parts has spend gently when wearing away, can produce slight noise.
The examination after disassembling; Look carefully at crusher bearing to roll whether group of steel of body, inside and outside has damaged, rustily, scar to wait first, hold bearing inner ring with the hand next, make bearing squares, another hand exerts oneself to do sth. outside pushing, just was encircled, if bearing is good, steel group should turn outside smooth, apparent vibration and card sluggish phenomenon are not had in roll, stop after turning outside steel group does not have retrograde phenomenon. Show bearing otherwise already cannot reoccupy. Left hand blocks outer lane, the right hand is held inside steel group, drive to each direction forcibly, if drive when feel very loose, wear away namely serious.
② breakdown repairs: The apparently rusty spot outside bearing can use sand paper erasure, put into benzine to clean next; Or bearing has crackle, inside and outside to encircle disintegrate or bearing excessive when wearing away, should change new bearing. Change when new bearing, want to choose as identical as former model bearing.
2, runner shaft corrective maintenance
① journal wears away; Journal wears away not quite when, can go up in journal plating a chromium, again grinding comes need dimension; Wear away relatively a long time, v can undertake on journal, burnish to the cutting on lathe again; If journal has worn away big when, also go up in journal turning 2-3mm, again car one sleeve, take the advantage of heat to cover go up in journal, next turning requires measure to place.
② axis bends; If crusher axis bends not quite, but through burnishing the method of journal, slip ring has repair; If bend,exceed 0.2mm, can put runner shaft at compressor, patting sinuosity pressurization correctional, correctional the axial surface after burnishs with lathe cutting; If had bent big, need to change new axis additionally.
3, calm, rotor core corrective maintenance
Calm, rotor is by the silicon steel of mutual insulation piece fold, it is the magnetic circuit part of electromotor. Calm, the attaint of rotor core and be out of shape basically cause by reason of the following respects.
① crusher bearing is excessive wear away or assemble undesirable, cause calm, rotor photograph is brushed, make core surface is injured, cause silicon steel then piece a short circuit, electromotor iron caustic increases, make electromotor temperature rise exorbitant. Apply the tool purify burr such as fine file at this moment, eliminate silicon steel piece short receive, the insulating varnish on the besmear after clearing clean, heat stoving.
When ② demolishs old winding, had exerted oneself to do sth. big, make alveolar and askew and stretch outwards. Right now the tool such as hammer of clamp of applied pointed mouth, wood gives nap, make alveolar restoration, be in the has crack silicon steel of bad restoration piece join the horniness insulating material such as board of fish paper, glue.
③ creates core appearance because of the reason such as be affected with damp be affected with damp rustily. Need to use sand paper burnish right now clean, the insulating varnish on the besmear after clearing.
④ produces chamfer of core of high fever burn down or tine ministry around group ground connection. The tool such as usable chisel or drawknife accumulates frit content eliminate clean, drying of the insulating varnish on besmear.
The union between ⑤ core and baseplate becomes loose, can screw bolt of original fixed position. Be like invalidation of fixed position bolt, can drill fixed position hole again on baseplate and tap, come back bolt of close fixed position.
Above is the crusher that SBM machine sums up for everybody the overhaul of common breakdown and eliminate a method, firmly control, have profit greatly to your production certainly.
- SBM is efficient and energy-saving make arenaceous machine dust control respect photograph to be highlighted than other equipment advantage
