Hydraulic System Maintenance Of Hydraulic Drilling Rig
Hydraulic technology of Hydraulic Drilling Rig is a new technology that develops late but develops rapidly. It is gradually developed on the basis of fluid mechanics. It mainly uses the pressure of the liquid to transmit the force and torque, the so-called hydraulic transmission. Proper use and maintenance of the hydraulic system is an important factor in ensuring the normal operation of the system and extending its service life.
(1) Prevent contamination of hydraulic oil. The pollution of hydraulic oil refers to the incorporation of air, moisture, dust and insoluble sediments generated by self-oxidation from the outside. The contamination of the oil will aggravate the wear between the relatively moving parts in the hydraulic components, resulting in throttling holes. Blockage or slipper motion is stuck, and the chemical stability of the broken ring oil accelerates the generation of oxides and the decomposition of organic impurities in the oil. According to statistics, more than 75% of hydraulic system failures are caused by oil contamination. As a result, the fuel tank should be properly sealed. It is forbidden to use oil-resistant seals and hoses, and regularly clean and replace the oil to prevent oil contamination and aging.
(2) Prevent the oil temperature from being too high. If the oil temperature of the hydraulic system is too high, the viscosity of the oil will decrease, the leakage will increase, the volumetric efficiency will decrease, the oil velocity will be unstable, the oil will deteriorate, and the air condition will be aging. In order to avoid excessive oil temperature, in addition to selection In addition to the recommended hydraulic fluid, the correct oil level in the tank should also be noted to ensure that the system has sufficient circulating cooling oil. At the same time, it is necessary to keep the amount of water in the cooler sufficient and the pipeline to be unblocked.
