Due to its compact structure, smooth, easy operation and energy etc, cone crusher hydraulic system is widely used in construction machinery. If use and maintenance undeserved, it will greatly improve failure rate, influent mechanical reliability and service life seriously. Therefore, it is necessary to talk about the method of proper use and maintenance hydraulic system.
Regular inspection hydraulic oil quality and keep hydraulic oil clean. In checking hydraulic oil quality, basically check the following three aspects:
1. In use, due to the change of the temperature, oxygen in air and sunlight, hydraulic cone crusher the role of the hydraulic oil would gradually by oxidation, make its viscosity properties change. The extent of the oxide, usually from hydraulic oil on the color, smell judgment. If the color of hydraulic oil is dark brown, and a stench already oxidation that taste. Brown, the deeper odorous flavour, then explaining oxidation with the more powerful the degree. At this point, should replace new oil.
2. Hydraulic cone broken oil contains moisture degree. The hydraulic oil mixed people moisture, if will reduce its lubrication performance, corrosion of metal. Judge hydraulic oil mix water level, there are usually two ways. One is according to its color and the change of odour circumstances, such as hydraulic oil color has milk-white, odour did not change, then explaining mixed people too much water. The other one is to take a few hydraulic oil droplets on the iron in the scorching heat, if PaPa voice, then issued that contains moisture. At this point, should replace new oil.
3. The hydraulic oil contains impurities. In the mechanical work after period of time, take few drops of hydraulic oil on hand and twist it in fingers, and see whether there are metal granules, or observe whether has small shining points in the sun. If there are more metallic particles or sparkle, the hydraulic oil contains more mechanical impurities. At the moment, it should replace hydraulic oil, or release the hydraulic oil out, settling for not less than 42h above time, then reuse it after filtering.
When hydraulic system break down, something abnormal phenomenon will often happened in advance. And earnest strictly daily inspection and maintenance, for timely hair and eliminate small fault, prevent big accidents, has the very vital significance.
