Let's talk about the wire rope inElevatorThe role of wire rope and the cause of wear

The elevator is mainly driven by the chain, and the wire rope is used as an auxiliary material to play the role of safety. The wire rope has two installation positions: one is installed next to the chain as a safety rope, which works when the chain breaks; the other is installed on the four corners of the platform As a balance rope to ensure the balance of the desktop.

Generally, steel wire ropes are exposed, the environment is harsh, the operating load is large, the tension is high, the internal and external friction is large, and the corrosion is rusty. Although many people regard steel wire rope as an industrial material, it is actually composed of many moving elements (steel wire, strand, lining core, etc.). When stretched, bent and twisted, each steel wire and lining core will produce friction and wear to each other.

traditionalElevatorWire rope lubrication method is generally manual, with a brush or other water suction tools in the wire rope coated with grease (oil), it should be noted that can not be heated butter, or grease (oil) is difficult to enter the wire rope, do only surface maintenance, simply can not achieve the desired maintenance effect.

wire rope wear in use:

1. Continuous wear and adhesive wear occur at the actual contact friction part;

2. Wear caused by the adhesion and combination of dust and abrasives;

3. If the wire rope is exposed to humid, acidic and alkaline gas environment, it will cause corrosion and chemical erosion;

4. Due to overload, impact or excessive bending, the steel wire structure changes, the strength is reduced, and fatigue occurs. This is a form that is naturally not easy to detect but will gradually accumulate and suddenly produce damage;

5. Due to the high specific pressure between the steel wires and between the steel wires and the rope wheel and the drum, the oil film strength is insufficient, and traces and deformation appear;

6. Wear caused by friction heat generated by direct contact with metal.

PurchaseElevatorSeveral parameters you need to know when

When purchasing a lift, you need to understand its service items, transportation capacity, characteristics in operation, as well as the provisions of civil design schemes such as hoistway and main engine room, so that you can buy your own equipment faster. The following are some parameters that you need to know when purchasing lifting equipment.

1. Rated speed: The operating speed of the equipment required for manufacturing or design schemes is expressed in m/s, which is a basic parameter. The typical speed of hydraulic elevators is 0.25 m/s and 0.1 m/s, and can be designed under special circumstances. Less than 0.5 m/s.

2. The specific situation of the hoistway: The elevator should be installed in a closed hoistway. The specific situation of the hoistway determines the specifications and dimensions of the equipment, which actually includes the total width, depth, bottom of the well and the status of the main machine room.

3. High-rise height: The height of the equipment from the bottom station to the high-rise station is very important, because the height of the high-rise building needs to meet the acceptance standards of our country.

4. Lifting height: When the lifting equipment runs from the next level to the packaging height of the previous level, it should be accurately measured. As the height increases, the length of the hydraulic cylinder will increase, and the price of the hydraulic cylinder will be more expensive.

5. The number of stations, the number of hearings, the number of kiln doors, and the price have a great influence.

6. Rated load capacity: The load capacity (Kg) required for manufacturing or design scheme is the basic parameter of lifting equipment, and the main parameters are customized according to customer satisfaction.

All right, let's talk about it today. Thank you for watching.
