Detailed information on daily maintenance of pulleys

The manufacturer of the lifting pulley tells you about the daily maintenance of the pulley. At present, pulleys are commonly used tools in our daily lives, and they are a very labor-saving device that has applications in most fields. Among them, hot rolled pulley is widely used and has its own high strength. People like functions are very popular, but they are usually maintained after the device is in use to extend its lifespan. So, what is the daily maintenance of pulleys? Let's take a look at the analysis below.

Introduction to the characteristics and advantages of hot-rolled pulleys

The appearance of the hot rolled pulley groove is moistened and wear-resistant, and can be heat treated, with good strength and durability.

Main functions and material matters of crane pulleys

In cranes, the main function of pulleys is to thread and wind steel wire ropes. Pulleys are divided into movable and fixed pulleys based on whether the central axis is moving or not; According to the manufacturing method, it is divided into cast iron pulleys, cast steel pulleys, welded pulleys, nylon pulleys, and aluminum alloy pulleys. Cast iron pulleys, including gray cast iron (HT1533) pulleys and ball plug cast iron (QT4010) pulleys. Grey cast iron pulleys have good technological performance, have little wear on steel wire ropes, but are fragile, and are mostly used in light and intermediate operation levels; Ductile iron pulleys have higher strength and impact toughness than gray iron, so they can be used in heavy-duty operations.

Causes of overheating in piston rod machining

(1) The piston rod and the ferrule joint are tilted during installation, causing some parts to rub against each other, and adjustment should be carried out immediately;

Piston rod design considerations

Piston rod is a connecting component suitable for piston rod work, most of which are used in hydraulic cylinders and cylinder fitness exercise components. It is a fitness exercise component with frequent fitness exercises and high technical standards. Taking the oil pressure cylinder as an example, it is composed of several parts: cylinder liner, piston rod, piston rod, and bearing end cap.

1. Use of machinery and equipment Product workpiece standards.

Routine maintenance of piston rod equipment

1. Check the integrity of the equipment, whether accessories are missing, and all tools and accessories should be placed and stored neatly.
