Are circular drill needs attention

- Nov 07, 2019-

Drill has the difference between positive and negative circulation, in use are circulating drilling rig, there are some problems needs attention, small make up for the six problems about together with everybody. Use positive cycle of rig note: host and winding to regularly check the oil level, if the lack of oil should be added in a timely manner. Hebei trailer rig work, should be ready to monitor electrical instruments, have abnormal sound, it is necessary to stop the machine immediately to check, not to work, in spite of all the fasteners check to prevent loosening. Drilling speed should vary according to stratum situation, control host electric hydraulic drilling slowly in rated range. Hydraulic lever to slow, quick operation, if small trailer rig too fast will damage the components and operation risk. Operators should always check whether oil leak, be careful not to hang, tubing pressure, so as not to damage the influence the work. If is circulation drill for a long time stop, should will withdraw the or oil cylinder a cloth.

Rotary water well drilling rig, it relies mainly on the rotary motion and broken rock and pore forming tool. Hebei trailer rig has five major types of cone. Using the pan tapered drill rotating cutting soil. According to the size of the drill respectively called cauldron and small pot cone, cone can be driven by human or power. Cut soil debris fell into the pot, to improve discharge to the ground. Its simple structure, low efficiency, suitable for general soil or sandy pebble soil layer. Small pot cone drilling depth of 80 ~ 100 meters, large cone is 30 ~ 40 meters. Pneumatic rotating disc drill wash well. On the wheel rotary drilling rig with air compressor instead of mud pump, the use of compressed air instead of mud to wash well. Usually adopts reverse circulation method, also called reverse circulation of gas lift. Trailer rig brand is suitable for the larger hole depth and water shortage in arid regions and frigid permafrost. Hydraulic power head drill. Driven by hydraulic motor through the gear reducer, and to move up and down the tower of power head instead of rotating disc on the rig rotary table and faucet, drive drill pipe and drill rotating cutting rock. To drill large diameter water well. DTH vibration of rotary drilling rig. With the combination of vibration and rotary motion way into layers.

1. Pay attention to the small trailer rig engines work load, the running-in period of the work load is generally not more than 80% of the rated load, and to arrange a suitable work, to prevent overheating phenomenon caused by the machine long time continuous operation. 2. Pay attention to always observe the instructions in the instrument, abnormal, should be ruled out, to stop the reason was not found, the fault before has not been ruled out, should stop work. In short, the engineering drilling machine of use and maintenance requirements during the running-in period, can be summarized as: to strengthen training, lighten the load, note to check, strengthen the lubrication. As long as pay attention to and implemented according to the requirement of engineering machinery maintenance and the maintenance period, will reduce the occurrence of early failure, hebei trailer rig prolong service life, improve the working efficiency, make the machine to bring you more benefits.
