mechanical components:
1.cleaning and lubrication of guide shoe for elevator car .we all know that guide shoe running on rails, the guide shoe above the cup, to make the elevator does not produce friction sound in the operation must be regularly to the cup and cleaning gas guide shoe, and should clean up the car's health.
2. elevator hall door and car door maintenance. elevator failures are generally in the elevator hall door and car door, so attention should be paid to the maintenance of the hall door and car door. one is that the fuel on the upper frame of the door is filled with oil to keep good lubrication, and the elevator will not make unpleasant noises in the running and opening of the door. note the touch panel switch line elevator safety contact plate or screen type check, because the high frequency of elevator door switch, the switch line is damaged, which requires maintenance personnel in every work should be checked, the change will change in advance, do not let the user because of the door of elevator products the quality of doubt.
3. elevator traction machine needs oil lubrication. there are two marks on the cover of traction machine, check the oil should be in the middle of the two scale nozzle is opened, if the oil is lower than the scale below, it should be said to oil machine, without refueling, operation will lift a long time not very good lubrication, which leads to burn down the elevator traction machine and motor the. after the elevator running for a long time, the oil should be replaced in time, so that the traction machine will always maintain a good lubrication.
electrical components:
electrical components can be divided into control panel, the safety circuit of electric switch, it is the lift of the brain, central nervous elevator, starting, running and switch the elevator door are dominated by it, so in the daily maintenance work must take it as a priority to treat. in the work, it is better not to carry on the short circuit of the elevator loop in the control panel. when the elevator door system failure, someone to the convenience of the elevator door to short connection, in order to find the fault, so it is dangerous, short door occurs most accidents. why? if a person opens the hall door and extends his head to the inside, then the elevator goes up or down to the point where the door is short and the elevator can't stop, so the accident is very likely to happen. so we in the daily maintenance work don't take safety loop to short circuit, if must be short circuited, to find out which parts of a problem, which need to short the security components, and emergency maintenance or repair, must be timely to take off the short connection.
although the increase in the number of elevator, elevator maintenance workload increases, but the maintenance unit should conscientiously do a good job of elevator maintenance work, strengthen safety inspection and supervision, to prevent accidents, in order to ensure the safety of people travel, which is the maintenance unit glorious and sacred duty.
