1. No matter what the situation well drilling rig operated under insurance regulations, when someone is working on the mast section, under the mast other staff are not allowed to stay. 2. In the event vile weather (rain, snow, ice, or more than five years of night wind), not allowed to work on the mast, hydraulic filters. At the same time, do not permit the use of artificial lighting in the mast. 3. Do not use wire rope split shares. 4. landing drill, severely curb touch the rope. 5. In addition to elevating drilling rig, drill pipe endures, open wellhead prohibited. 6. In order to avoid drilling or pumping tube wells outside swinging from the well when pulled, the hook must be applied by 15 ~ 20mm diameter steel bars made of hook. 7. cleaned pumping tube, you should use a solid robust rope looped, set in the lower end of the pump cylinder, which is spilled, CSM. 8. Use the pulley casing promotion or landing when and machinery at the salvage work, all workers should be separated from the drilling. 9. When the casing is pulled out by lifting rig sale, in order to prevent the sleeve off, fixed to each other in the way necessary. 10. In the case of the next stop light (night time), well drilling rig work should be stopped. This time when the well is still drilling, the drill should be vigilant taken out from the well. Troubleshooting common submersible drilling rig, before using submersible drilling rig is easy to overlook the three points when using there will be some failures, some failures are due to quality caused submersible drilling rig itself, some are due to improper operation caused submersible drilling rig. Submersible drilling rig failure, maintenance is too much trouble, would delay the construction period. This requires that the user must submersible drilling rig for submersible drilling rig works have a certain understanding of the common failure to make some proper placement. Before entering the submersible drilling rig, the rig site must be flat Which is good, ready skids tools. After entering the rig rig Which cheap rig skids must elevate the tire off the ground, and adjust the rack into a horizontal position: When powered on, the motor can be started, lifting mast, after lifting mast, mast Unscrew the screw at the bottom, and support to the carriage; then lever frame legs, stretch strap attaching good, and the adjustment screw to adjust the rod, guy wire tension degree. DTH drill rig rope drum roll led by the impact of self-beam guide pulley and tension pulley sheaves re-entry drilling mast top and sagging, its end and took the rope attached to the joint drill. Mud mud drum rope through the top of the mast sheave and sagging, so the tip is connected to the mud of the barrel. Submersible drilling rig to the bottom of the mast auxiliary reel three fixed pulley used in conjunction. Which is cheaper rig, Long industry machinery (certified), the rig is provided by Shandong Machinery Co., Ltd. Dragon. Shandong Machinery Co., Ltd.
