Talking about the daily maintenance and maintenance of the elevator installation of the villa
A brief discussion on the inspection of the steel wire rope in the maintenance of the villa elevator is divided into external and internal inspection. External inspection is to observe the external defects such as corrosion and deformation on the surface of the wire rope. The vernier caliper is used to measure the diameter of the wire rope to check its wear degree, and visually check whether the visible broken wire number of the wire rope exceeds the scrap standard. The experience of inspection and rejection of copper wire rope shows that the internal damage of wire rope is mainly caused by corrosion and normal fatigue, which is the primary reason for the failure of many wire ropes. The usual external test can't find the extent of internal damage, even to the danger of approaching fracture. Therefore, it is very necessary to inspect steel wire internally.
1. How does the elevator run?
The villa elevator has a car and a pair of weights. It is connected by wire rope. The wire rope is driven by the traction device (traction machine) to make the elevator car and the elevator moving up and down on the guide rail of the elevator.
2. Will the steel rope of the villa lift be broken?
The steel wire rope used in the elevator is special for the elevator, and the state has special regulations and requirements. The wire rope configuration not only for take the elevator car and rated load, but also taking into account the traction force size, therefore, the tensile strength of steel wire rope is much larger than the load of the elevator, the safety coefficient are above 12, usually lift more than four are equipped with wire rope, general elevator the wire rope is not broken at the same time. The safety factor of the elevator is very high. If the wire rope is broken, the elevator will be discontinued and will be put into use after the wire rope is replaced.
3. Is there a danger in the abrupt blackout of the elevator in the villa?
In the operation of the elevator, if there is a sudden outage or failure of the power supply line, the elevator will stop running automatically, and there will be no danger. Because the elevator itself has electrical and mechanical safety devices, once the power outages, the elevator brake will automatically brake, so that the elevator can not run. In addition, if the power supply department has a planned outage, the elevator will be notified in advance, and the elevator will be stopped in advance. When the elevator is out of power, the bottom of the car has a safety clamp, it will hold the guide rail, the car is fixed on the guide rail, will not slide. Some elevator control cabinets have emergency power supply. After a sudden blackout, the power in the emergency power supply is enough to send the car to the nearest floor, and open the door to let the passengers out safely.
The overall design of the lifting equipment does not allow the wire rope to have an unlimited long service life. Strictly speaking, after the wire rope is put into use, its performance begins to decrease. The wire rope must be regularly inspected according to the regulations during its operation. It can provide a basis for safe and effective use of wire rope through real-time monitoring of steel wire ropes. Usually, the inspection of the wire rope is divided into external and internal inspection. External inspection is to observe the external defects such as corrosion and deformation on the surface of the wire rope. The vernier caliper is used to measure the diameter of the wire rope to check its wear degree, and visually check whether the visible broken wire number of the wire rope exceeds the scrap standard.
The mechanical part of Guizhou lift the quality of relatively more stable, but some life is too long, or serious mechanical wear mechanism in the design and manufacture of the inherent problems, such as the old domestic elevator door, followed by the emergence of various faults with various conditions, seriously affect the use. On the basis of the original, the elevator will be reformed locally or extensively, so that it can be used safely and reliably, reduce the failure rate and make the reformed elevator reach the current technology level. The elevator of Guizhou is here today. If there is nothing to know, we can come to our company to understand the situation.
