Rig Hydraulic System Troubleshooting performance rig hydraulic system for the implementation of components ------ hydraulic cylinders, hydraulic motors power shortage; if rigs all hydraulic actuators are not strong enough, the main consideration Rig systemic problems, first of all hydraulic pressure or flow is whether the requirements of a more direct way is to use a pressure gauge to test the system; furthermore consider checking system relief valve leaks. Relief valve seal replacement lax relief, so the simplest operation, the lowest price; hydraulic pressure is insufficient to replace the pump, relief valve and pump are generally non-serviceable parts, should be replaced as a whole; if it is less than one action force, it is a problem with the actuator, hydraulic cylinder ----- consider unloading the fuel tank seal is broken or damaged hydraulic lock; in this case replace the hydraulic lock or replace cylinder seals. Brief well drilling rig working methods in recent years, as China's economy at the same time increasing levels of rig accessories, water scarcity is becoming a serious problem, most regions have started drilling, so that drilling in what machinery and equipment, of course, is a long auger drilling rig, which is characterized by advanced structure, the auxiliary convenient, use a short time. Well drilling rig working process is inseparable from the use of the pump, use pump trans loop. Under atmospheric pressure, the circulating fluid from the settling tank through the return ditch along the annular gap flow borehole bottom, perform cycle of work, the formation of reverse circulation drilling.
