Abstract
The utility model relates to a bypass filtration system of rotary drilling machine belonging to the bypass filtration system. The filtration system comprises a filter, a main oil return pipe and a fuel tank. A bypass oil pipe is disposed on the main oil return pipe, and connected to the fuel tank through the filter. The filter is a box, in which are disposed a filter core having the netted structure. A small flow fraction in the hydraulic system main oil return pipe, which is approximately equal to 1% of the whole return oil volume, can be drained for the circulation filtering, and all the oil in the fuel tank can be filtered through the gradual, continuous circulation. Because the filter core is the netted-structured cellulose having the hydrophilic and water absorption property, thereby the pollution particles having the size of 1 micrometer can be adsorbed. The bypass filtration system provided in the utility model has advantages of simple installation, convenient maintenance, low costs, ability of effectively absorbing the water and granules in the hydraulic system, cleaning the oil, reducing the system faults, improving the cleanliness of the rotary drilling machine hydraulic system, protecting elements, and prolonging the service lifetime of the oil.
Description
Technical field
The utility model relates to a kind of bypass filtration system of bypass filtration system, particularly a kind of rotary drilling rig.
Background technique
Pollution in the hydraulic system (comprising solid particle, water, air) is the main cause that causes hydraulic system fault, in the hydraulic system of rotary drilling rig, because the fault that causes of hydraulic oil pollution is also more, such as: spool wearing and tearing, stuck etc.Because rotary drilling rig multiselect Proportional valve, servovalve etc., its dustiness to fluid requires very high, and the full flow return filter can't be removed a lot of fine particles, and can't filtered water, and therefore the full flow return filter being set in pipeline merely can not deal with problems fully.
The model utility content
The purpose of this utility model is to provide a kind of: the bypass filtration system of rotary drilling rig, solve a lot of subparticle that the full flow return filter can't be removed, and problem that can't filtered water.
The purpose of this utility model is achieved in that filtration system comprises filter, main return line and fuel tank, be connected with the bypass oil pipe on main return line, the bypass oil pipe is by the filter connected tank, and filter is a casing, filter core is arranged in casing, and filter core is a reticular structure.
Beneficial effect, owing to adopted such scheme, in system, increase a kind of online, lasting bypass filtration system, from hydraulic system master return line, draw the sub-fraction flow, be about 1% of total recirculating oil quantity and carry out circulating filtration, by progressively, continuous circulation makes the fluid in the fuel tank reach whole filtrations.Because the filter core that uses is cancellated cellulose, has speciality hydrophilic, suction, when absorbing moisture, adsorbable little contamination particle to 1 μ m, solved a lot of subparticle that the full flow return filter can't be removed, and problem that can't filtered water reaches the purpose of this utility model.
Advantage: this bypass filtration system is installed simple, easy to maintenance and cost is lower; effectively water and the molecule in the adsorption liquid pressing system cleans fluid, effectively reduces the system failure, improved the turbidity test of rotary drilling rig hydraulic system; protect element, prolonged the working life of fluid.
Description of drawings
Fig. 1 is a hydraulic schematic diagram structural drawing of the present utility model.
Among the figure, 1, filter; 2, main return line; 3, fuel tank.
Embodiment
Embodiment 1: filtration system comprises filter 1, main return line 2 and fuel tank 3, be connected with the bypass oil pipe on main return line 2, the bypass oil pipe is by filter connected tank 3, and filter 1 is a casing, filter core is arranged in casing, and filter core is cancellated cellulose.
The bypass filtration system is installed simple, easy to maintenance.More during renew cartridge, open upper end cap, take out filter core and get final product.
