Current domestic drilling rig industry due to its technical limitations, it is difficult to meet the development needs of foreign high-end customers, but for developing countries, especially some of the more backward countries in Africa, still has a strong competitive to meet different development needs of customers in different regions, especially in some backward countries is growing rapidly in recent years, so the drilling rig industry, exports sales will remain a good growth rate. 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, have to do a full hydraulic drilling rig maintenance work. Full hydraulic drilling rig adopts full hydraulic drive system 50 type drilling rig equipment, such a hydraulic system stability 50 type drilling rig manufacturers, largely depends on the hydraulic system used in the hydraulic oil, hydraulic engineering drilling rig System 50 type drilling rig much money, the viscosity of the hydraulic oil is an important factor to 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 increased 50 type drilling rig, 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. 50 type drilling rig where to sell the Prius, JieXi 50 type drilling rig provided by Luoyang Prius Drilling Equipment Co., Ltd.
