3 detects when the gondola electrical box leakage protection tripping
① power cables connected correctly (then back to ground zero, check the cable connection is correct); ② damage leakage protection (in other leakage protection); ③ use 220V power supply (check the zero ground connection is correct)
4 hoist large lid following the oil spill
① Φ230 seal damage (down gently to seal the φ230); ② box trachoma (casting Putty or two good brother to trachoma mended); ③ small cap oil spill (to open the four M5 screws, the oil dry, add a liquid sealant, drying at 30 ° temperature for 2 hours, you can press on)
5 ring gear installed in place
① not bleed (to release the filling hole, then gently press down with a sledgehammer smashing down);
② bearing units stolen goods (clean up stolen goods)
Twisted rope hoist after repairs 6
① points deduction seizing rope fixed block (with open drill φ6.5 mounting holes with M6 screws installed); ② strip holder seizing (with professional Putty mended, repaired or returned to the manufacturer); ③ deformed steel (adjustment reset or replace steel); ④ large box and lid seizing (replacement or repair filler and welding); ⑤ pressure roller deformation (adjust or replace pressure roller press wheel)
7 Press the up switch, KM1 not work
① limit switch is damaged (check the limit switch is normal, the terminal is loose or dropped, replace the limit switch); ② motor aviation plug disconnected (check whether the sealing off air plugs); ③ KM2 contacts of 31.32 points damage (replace KM2 contactors); ④ KM1 contactor coil burned (replace KM1 contactor)
8 elevator can not start
① power connector is not plugged in securely (plug plug); ② start button damaged (replace the start button); ③ thermal relay capacitor is not reset (press the reset button); ④ leakage protection trip (to exclude leakage reclosing after remission)
9 ring does not turn the motor only, with fixed working platform
① phase (three-phase power to check the situation, whether the virtual access lines, power outages, each connector is connected securely); ② inside the motor phase failure (motor replacement); ③ rope stuck in the elevator inside (demolition hoist and remove the rope , maintenance elevator)
10 after falling off the motor automatically
① small spring pressure on the brake armature (down 3 M5 fastening screws); two M5 screws ② manual clutch armature hid on tight cause friction disc (adjustment, M5 screw); ③ contact failure, each stop the motor has slipped times regular 250px-500px (upstream and downstream switches are several times in quick succession jog); ④ open hand brake (hand brake return to normal position); ⑤ motor brake gap is too large (adjusted four weeks a gap of 0.4mm-0.6mm)
11 hoist with fixed working platform
① phase (three-phase power to check whether a bit); ② power supply voltage is too low (check and adjust the voltage); ③ the rotational position of damage (check hoist); ④ Brake does not open or fully open (pitch and check brake adjustment); ⑤ pinch roller lever deformation mechanism (inspection or replacement of the lever)
12 Hoist live shell
① motor damp (be dried shell hit isolated lead); ② loose or broken ground wire (repair or change)
13 side of the hoist motor does not move or smoke heat
① does not operate the brake armature or armature with friction disc spacing is too small (to adjust the gap or replace armature); ② brake coil burned (replace the brake coil); ③ rectifier short-circuit damage (replace rectifier); ④ thermal relays or contactors damage (replace the corresponding electrical devices); ⑤ switch is damaged (replace switch)
14 Hoist brake does not work
① no DC voltage (check for 99V DC voltage); ② rectifier diode is damaged (replace diode); ③ gap is not adjusted (to adjust the gap to 0.4mm-0.6mm); ④ brake coil is damaged (replacement brake)
15 limit switch does not work
① power phase sequence reversal (switching phase sequence); ② limit switch is damaged (replacement limit switch); ③ limit switch bad contact with the stopper (adjust the limit switch or stopper)
16 Security lock does not lock the rope
① interlocking spring damage (exchange spring or Depot Repair); ② The lock dirt or soil too (open the cleaning with gasoline or thinner); ③ not wearing rope in rope folder (the folder to wear in the rope)
17 security locks rope angle
① security lock rope clamp L or R excessive wear (adjust the security lock guide sheave security ring position or replace the L or R); ② rope surface oil (with thinner or gasoline to clean wire rope or replace the wire rope); ③ suspension ends agencies the inside of the distance is greater than the size of the platform (the platform suspension mechanism is adjusted to be greater than the size of 10-20 cm)
18 security lock small lock rope angle
① security lock brake and the pendulum axle joints damaged (replace pendulum); stick dirt (open the cleaning) between R and L ② safety locks folders; ③ suspension mechanism ends distance smaller than the inside dimensions of the platform ( the suspension mechanism is adjusted to be greater than the platform size 10-20 cm); ④ safety lock with sidebar webs at the back there is the phenomenon (with a professional tool to reset or webs Depot repair sidebar)
19 Two motors are not synchronized
① motor brake sensitivity difference (gap adjustment motor brake); ② centrifugal governor spring relaxation (replacement of centrifugal speed spring); ③ motor speed difference hoist rope pull difference (voltage or replace the rope device check hoist rope pressure means replacement of incorrect motor rotation speed; within ④ uneven load platform (platform load adjustment)
20 suspended platform can not be lowered when the roof was raised
① two suspension mechanism spacing is too small, so that the safety lock from the lock (suspension adjustment mechanism spacing)
21 penetrates the work rope hoist
① rope end welding problems or curved (polished welding parts or rope ends remake); ② lift the machine a foreign body (open hoist remove the foreign body or replace the hoist)
22 abnormal wear rope work
① support assembly wear (replacement support assembly); ② press agency rope wear (replacement cord compression mechanism); ③ guidewire block wear, damage (replace the guide rope blocks)
23 two socket without power
① no zero line (zero line to check if connected); ② leakage protection damage (replace leakage protection)
