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, it 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. 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 strong enough drilling rig, the main consideration systemic problems, first of all hydraulic pressure or flow is whether the requirements percussive drill, 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 long auger easiest, lowest price; hydraulic pressure is insufficient to replace the pump, relief valve and pump are generally non-serviceable parts rig, have overall replacement; if it is less than a certain 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. Well drilling rig, Long industry machinery (certification), the rig by Dragon Machinery Co., Ltd. Shandong. Machinery Co., Ltd. Shandong Long (www.longyejixie.com) is Tai'an, engineering machinery parts leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lung industry machinery leadership with the staff warmly welcome all inquiries negotiations to create the dragon industry machinery better future.
