Prevent the Hydraulic System of a Water Well Drilling Rig from Being Contaminated

How to avoid contamination of the hydraulic system of the water well drilling rig, we need to pay attention to the following points:


1. The hydraulic accessories and hydraulic components of hydraulic system of the water well drilling rig 


Try to select hydraulic accessories and hydraulic components with low pollution sensitivity for hydraulic system of the water well drilling rig.


2. Oil filter device of the hydraulic system of the water well drilling rig


Correctly select and reasonably arrange the oil filter device of the hydraulic system of the water well drilling rig to ensure that the filtration efficiency, filtration accuracy, and pollution holding capacity of the system meet the design requirements, and the system has sufficient pollution steady-state period and pollution self-purification ability.


3. The structural design of the hydraulic system of the water well drilling rig


In the structural design of the hydraulic system of the water well drilling rig, it is necessary to minimize and eliminate pollution sources (reduce the value of the pollution generation rate) to make the system work with less invading pollution. If an isolated oil tank or closed system design is adopted, the oil discharge and exhaust devices should have reliable anti-pollution measures to avoid pipeline dead ends and blind ends.


4. The internal structure of the hydraulic components and hydraulic accessories of the hydraulic system of the water well drilling rig


The internal structure of the hydraulic components and hydraulic accessories of the hydraulic system of the water well drilling rig should facilitate the removal of pollutants, so that the pollutants are not easy to stay and silt. To minimize blind holes and dead oil areas at the blind end, the internal structure of cast, forged, and welded parts should facilitate the removal of molding sand, welding slag and oxide scale.


5. The hydraulic system of the water well drilling rig uses working fluids and materials with high abrasion resistance. 


Hydraulic oil for water well drilling rigs must have a suitable viscosity and a suitable level of solid particle pollution. In addition, the anti-oxidation, anti-emulsification and anti-wear additives of the hydraulic oil should also be considered. At the same time, it is also necessary to consider the compatibility of the hydraulic working medium with the component metal material and its sealing material.


6. The hydraulic system of the water well drilling rig should consider the influence of the main system parameters


The hydraulic system of the water well drilling rig should consider the influence of the main system parameters such as oil pressure, temperature and flow rate on pollution control, and try not to arrange components and accessories in high temperature areas.
