The all-hydraulic water well drilling rig is a highly efficient and versatile drilling equipment. It is mainly used for drilling wells, agricultural irrigation wells, ground source heat pump wells and other wells. It is especially suitable for water intake projects in mountainous and rock formations. The rig can be used for drilling on different formations with a maximum diameter of up to 300mm.In addition to drilling wells,it is also suitable for the geological exploration of railway, water conservancy, bridge, dam foundation and other buildings, as well as some other projects,such as, geological core drilling, small grouting hole, blasting hole, etc..

Harm of Hydraulic System Pollution of Engineering Drilling Rig
If the hydraulic system of the engineering rig is polluted seriously, the system performance will be significantly reduced and the movement will be out of adjustment. In the various pumps, valves, motors and other components of the hydraulic system of the engineering rig, there are strict gaps between the relative moving parts, the matching surface of the precision parts, and there are many damping holes, gaps or control valve ports, etc. If there are more contaminants, these gaps and holes will be blocked, so that the hydraulic components will not work properly. If the contaminant enters the matching gap between the valve body and the cylinder block, it is easy to scratch the mating surface, so that the leakage continues to increase, and the dynamic response capability of the machine is deteriorated, so that the component eventually fails. Contaminants can also stick to the mesh of the oil filter, causing the pump to empty, creating cavitation and large vibrations of the machine.
Hydraulic System Maintenance of Hydraulic Drilling Rig
Hydraulic technology 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, 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 prolonging 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 sliding valve movement 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 the oil temperature being too high, the recommended hydraulic oil will be selected in addition to the recommended hydraulic oil. Attention should also be paid to the correct level of oil in the tank to ensure that the system has sufficient circulating cooling oil. At the same time, it is necessary to keep sufficient water in the cooler and smooth pipeline.
How to Improve the Production Efficiency of Hydraulic Water Drilling Rigs?
1.After the drill bit of the hydraulic water well drilling rig is drilled into the structure, the center drilling tool needs to be replaced in time. First ,you need to clean the bottom of the hole and then blow off the residue at the bottom of the hole. After the drill bit stops rotating, the drill bit in the hydraulic water well drilling rig is drilled. It is most suitable when the lifting force is slowly increased and the lifting force is just enough to lift the drill bit.
2.The drilling process summarizes the drill bits of the hydraulic water well rig. It is also necessary to pay close attention to the subsequent working conditions of the casing, to know the specific conditions of the drilling in time, to clean the drilling holes in time, and to drill the drill bit on the water drilling rig. Strong lifting is prohibited during this process.
3. There will be more residue at the bottom of the hydraulic well rig. The eccentric drill bit will be stuck by the slag and affect its collection and production. At this point, it is necessary to deliver compressed air and clean the holes again. And let the down-the-hole hammer work for a short time, the water well rig model, and then re-do the center drilling lifting work.
