Abstract
The utility model discloses a lubricant charging device for sand removing pumps, which comprises a compressed air guide tube, air switches, a pneumatic control valve, an exhaust valve, a pressure regulating valve, a piston, an oil storing cylinder sleeve and a cut-off valve. The utility model is composed of two paths, wherein a first path air switch is sequentially connected in series with the exhaust valve, the pressure regulating valve and the oil storing cylinder sleeve through the compressed air guide tube, and the oil storing cylinder sleeve is connected in series with the cut-off valve though a hydraulic oil tube; the cut-off valve is connected to a sand removing nozzle tip through the hydraulic oil tube. A second path air switch is communicated with the pneumatic control valve through the compressed air guide tube, and the pneumatic control valve is connected to a pneumatic control clutch through the compressed air guide tube. The utility model can carry out continuously self-sealing lubrication for a transmission shaft of the sand removing pump and has the advantage of good effect.
Description
Technical field the utility model relates to a kind of oil drilling lubricating fitting that removes sand pump.
Background technique is in Process of Oil Well Drilling, along with constantly creeping into of drill bit, the shaft bottom landwaste is constantly taken out of well head, for landwaste is leached, need ceaselessly sift out with vibrating sieve, need again simultaneously further to filter, to guarantee the stable and reliable for performance of mud with removing sand pump, mud is recycled repeatedly, remove sand pump and be the important corollary equipment of the rig mud system that petroleum drilling operation widely adopts.Desanding pump work environment more badly needs long-time running, for guaranteeing its proper functioning, will be in time in its running with manual type to the transmission shaft lubricant oil of annotating.Put in place because aspects such as desanding pump structure design, lubricant oil are difficult to filling, remove sand pump mortar in day-to-day operation simultaneously and very easily leak, its transmission shaft and seal arrangement serious wear reduce even operational failure its operating life.Therefore, situ of drilling well remove the sand pump lubricant oil of can not annotating automatically, the maintenance-free performance that removes sand pump is poor, has directly influenced working life of removing sand pump and the desanding effect that removes sand pump.
The summary of the invention the purpose of this utility model designs a kind of desanding pump lubrication agent filling apparatus exactly, can not annotate automatically and removes the technical problem that the sand pump maintenance-free performance is poor, the life-span is low to solve desanding pump lubrication agent.A kind of desanding pump lubrication of the utility model agent filling apparatus, it comprises air-pressure duct, air cock, Pneumatic valve, outlet valve, pressure regulator valve, piston, oil storage cylinder sleeve, stop valve.The utility model is made up of two-way, first via air cock is in series with outlet valve, pressure regulator valve, oil storage cylinder sleeve successively by air-pressure duct, by hydraulic oil pipe and stop valve series connection, stop valve is connected to except that on the sand pump oil nozzle by hydraulic oil pipe again the oil storage cylinder sleeve again.The second road air cock links by air-pressure duct and Pneumatic valve, and Pneumatic valve is connected on the pneumatic control clutching device by air-pressure duct again.Be connected on the compressed air cylinder respectively again at air source inlet place air cock and Pneumatic valve.In the oil storage cylinder sleeve piston is installed, the top of piston is filled with oiling agent, and scale is installed on piston.The utility model is used lubricating grease instead and is substituted lubricant oil, is power with pressurized air, and it is lubricated, respond well that this device can carry out continuously sealing automatically to the desanding pump drive shaft.Through practice, this device can make the desanding pump work life-span prolong more than one times, has improved working efficiency, has saved the oiling agent consumption, greatly reduces the manual maintenance cost.
Description of drawings Fig. 1 is a structural representation of the present utility model.1-compressed air cylinder among the figure; The 2-air-pressure duct; The 3-air cock; The 4-Pneumatic valve; The 5-outlet valve; The 6-pressure regulator valve; 7,8-pressure gauge; The 9-scale; The 10-piston; The 11-oil storage cylinder; The 12-stop valve; The 13-hydraulic oil pipe; 14-removes sand pump; 15-pneumatic control clutching device.
Embodiment is with reference to accompanying drawing 1, a kind of desanding pump lubrication of the utility model agent filling apparatus, it comprises compressed air cylinder (1), air-pressure duct (2), air cock (3), Pneumatic valve (4), outlet valve (5), pressure regulator valve (6), pressure gauge (7) pressure gauge (8), scale (9), piston (10), oil storage cylinder (11), stop valve (12), hydraulic oil pipe (13).The utility model is made up of two-way, first via air cock (3) is in series with outlet valve (5), pressure regulator valve (6), oil storage cylinder sleeve (11) successively by air-pressure duct (2), by hydraulic oil pipe (13) and stop valve (12) series connection, stop valve (12) is connected to except that on the sand pump oil nozzle by hydraulic oil pipe (13) again oil storage cylinder sleeve (11) again.The second road air cock (3) links by air-pressure duct (2) and Pneumatic valve (4), and Pneumatic valve (4) is connected on the pneumatic control clutching device (15) by air-pressure duct (2) again.Be connected in respectively again on the compressed air cylinder (1) at air source inlet place air cock (2) and Pneumatic valve (4).Piston (10) is installed in oil storage cylinder sleeve (11), and the top of piston (10) is filled with lubricating grease, and scale (9) is installed on piston (10).Its working principle is, open air cock (3), connect compressed air cylinder (1), the compressed air conduit of pressurized air (2), outlet valve (5), pressure regulator valve (6), enter oil storage cylinder sleeve (11) bottom, pressurized air promotes to move on the piston (10), extruding lubricating grease, thereby open stop valve (12), lubricating grease then injects the lubricant housings of desanding pump drive shaft.Meanwhile the pressurized air part by air cock (3) flows to Pneumatic valve (4), and opens Pneumatic valve (4), and pressurized air flows to pneumatic control clutching device (15), makes clutch, thereby connects power, drives to remove sand pump (14) running.Scale (9) can show the storage of lubricating grease in the oil storage cylinder sleeve, and pressure regulator valve (6) is adjusted compressed air pressure, and then control grease adding pressure and adding amount.Pressure gauge (7) and pressure gauge (8) show the filling pressure of compressed air pressure and lubricating grease.When closing air cock (3) cut-out compressed air gas source, system quits work, and residual air is discharged from outlet valve (5).
