When the drilling rig friction pad wear, more needs to be adjusted periodically need to remove the adjustment nut fixing pin large drilling rig on the adjustment, turn to the right, the pins move into the new position of the cam ease the pressure plate closer. Rig friction film production will also appear in the production of large-scale drilling rig works slipping, skidding also affect the production efficiency, this time you need to pay attention to the situation of lubricating oil, lubricating oil adding too much if it would cause skidding, the need for timely clean to avoid slipping too much influence Rig production process. The importance of full hydraulic drilling rig production stability, and seriously affect the understanding of stability for the production of quality and production, and therefore fully hydraulic drilling rig in the production process of large engineering drill production lines, we must do the full hydraulic drilling rig maintenance work . Full hydraulic drive system uses full hydraulic drilling rig, the stability of the hydraulic system, largely depends on the hydraulic system used in large-scale projects of hydraulic oil rig manufacturers in the hydraulic transmission engineering drilling rig, the hydraulic oil Viscosity is one of the important factors that must be considered. Hydraulic system of hydraulic oil viscosity is too large, the pressure loss and heat flow of large hydraulic drive system efficiency. The viscosity is too large, it will cause leakage increases, the hydraulic drive system also affects the efficiency of the production. So full hydraulic drilling rig should select the appropriate viscosity and good viscosity-temperature characteristics, and also need to have a high film strength, good lubricating properties, good oxidation resistance and good stability. The correct choice of hydraulic oil is related to the stability of the entire drilling rig production, so when the choice must be strict requirements, in strict accordance with the manufacturer's recommendation to choose hydraulic oil, remember that different types of hydraulic oil can not mix, to prevent the production process appear affected.
