The most commonly used connection method rig Shandong Dragon Industry Machinery Co., Ltd. is professional development, production of various types of mining equipment backbone enterprises, the production of various types of submersible drilling rig, water well drilling rigs and other products. Today, let us work together to understand the connection requirements for crawler drilling rig: The rig currently used connection method (1) snap connector technology, mainly used for metal pipe. Threaded connection can be divided into male and female connections and then planting snap connector. (2) welded connection percussion drills, water well drilling rig is divided into welded connection, mainly used for large-diameter pipe for quality: plastic welding, mainly used for plastic pipe. (3) screw connection, and more for large diameter shallow wells. (4) adhesive, mainly used in plastic pipe and glass pipe. (5) socket connection, mainly for shallow wells, down into the bell handcuffs iron pipes and hard PVC pipe. Submersible drilling rig maintenance introduction submersible drilling rig maintenance among long auger, diesel engine bearing the brunt of it is the source for the rig of the hydraulic system, which directly affects Drill climbing ability, promote (boost) power, rotary torque and chisel Rock efficiency, timely maintenance and repair are submersible drilling rig to play the best efficiency of the premise. 1, diesel new or overhauled before use must be run-in, in order to improve the reliability and economic life of the diesel engine. Running at less than 70% of rated speed, and 50% of the rated load of 50 hours. 2 ,, should be shut down after a run-in hot oil sump release, with the diesel fuel to clean the oil pan and oil network, change the oil and filter after break-in period should be replaced every 250 hours per working oil and filter . 3, class clean up the air filter to prevent the diesel engine cylinder.
