ST 50 Portable Water Well Drilling Rig Advantages
Start drilling:
Push on the clutch handle and reducer handle, the mud pump starts to supply water, press the hydraulic right handle and rotate the left handle pressure regulating valve to start drilling. When the vertical shaft of the rotator falls to the bottom, pull down the clutch handle to cut off the power. Lift the support ring, lift the right hydraulic handle up to the up position, press the left hydraulic handle, lift the vertical shaft to the highest position, press the support ring, push up the clutch handle, press the right hydraulic handle down to the down position, start drilling again, operate repeatedly according to the above operation mode until the maximum drilling depth of the active drill pipe is reached, and then replace and install the drill pipe.How can a person change the drill pipe? First, pinch one end of the locking handle with the cushion fork, pull a three meter drill pipe into the hole with the puller, remove the puller, close the closing box, pull down the operating handle of the drilling rig ect
Inspection procedures for core drilling rig
I. Routine appearance inspection
(1) Regularly check whether the paint on the surface layer of the drilling rig is loose, mainly whether the operating parts are rusty;
(2) Regularly check whether the reinforcement is loose;
(3) Regularly check the welding position for faulty welding and desoldering.
II. Idle test run
(1) Carry out no-load actual operation of the drilling rig according to the safety operation procedures, and idle for 20 minutes;
(2) Regularly check whether the operation of the hydraulic transmission system is OK, whether the hydraulic seals, oil pipes and connectors have oil leakage, whether the temperature is OK, and whether the vacuum pressure gauge is OK;
(3) Regularly check whether the reinforcement is loose and whether various practical operations are sensitive and reliable.
