Today, the professional technicians of China Coal mucking loader will explain to you what are the components of the hydraulic system of the slag loader? Mainly hydraulic oil, control components, power components, executive components, auxiliary components.
Among them, the power element of the mucking loader hydraulic system mainly converts the mechanical energy of the motive force into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which supplies power to the entire hydraulic system. The structure of the hydraulic pump of the slag slag machine generally includes gear pumps, vane pumps and plunger pumps. The vane pump has relatively stable motion, high volume power, and low noise, but its operating pressure is low, and its oil absorption capacity is poor. The pollution is more sensitive, generally only used on small mucking loader.
Gear pumps are small in size, low in cost, reliable in operation, and less sensitive to hydraulic oil pollution, so they are widely used in various types of mucking loaders and electric excavators. Due to its high speed, high volume rate, and relatively high operating pressure, the plunger pump has the advantages of simple structure and variable functions, and is now widely used in large-scale slag scrapers. With the advancement of science and technology, gear pumps are becoming higher-pressured. The highest operating pressure abroad has reached 20-26Mpa. It is expected that its use will be further expanded.
