Based on the characteristics of the rig, rig classification method is different, the following list about two things: 1, depending on the place of use, submersible drilling rig can be divided into two categories underground and open. Downhole submersible drilling rig can be divided according to whether the running gear of two self-propelled and non-self-propelled; our open hole drill more, mostly for self-propelled. 2, in accordance with different pore sizes, submersible drilling rig can be divided into light submersible drilling rig (pore size of 80 ~ 100mm) tunnel boring machine, medium submersible drilling rig (pore size of 130 ~ 180mm), heavy-duty submersible drilling rig (pore size of 180 ~ 250mm) Leasing Co., Ltd. Shanxi Qishan compressor rig lease of used, recycled, rental business, welcome to buy! Compressor Rental Co., Ltd. Shanxi Kisan: to reduce the impact of mechanical impurities: mechanical impurities generally refers to some metal shavings, wear products such as dust, soil and other non-metallic materials and mechanical engineering in the course of self-generated. Once these impurities into the machinery inside, reach drilling machine maintenance between the mating surfaces of machinery, the harm is great, not only out of the block relative motion, accelerated wear and tear parts drilling machines, and will scratch the mating surfaces, damage lubricant film, the part temperature, oil deterioration. According to the determination, the lubrication of mechanical impurities to 0.15%, the engine of the first piston ring wear rate is 2.5 times larger than normal; when you scroll over the shaft into the impurity particles, their life will be reduced by 80% -90%. Therefore, working in the harsh environment, the conditions for complex engineering machinery spaces, one should use high-quality, matching parts and lubricants, greases road drills, to block the source of harmful impurities; Second, we must do the work site mechanical protection work to ensure that the appropriate agencies can work to prevent all kinds of impurities into the machinery inside. Mechanical malfunction, try to repair regular place for repairs. When on-site repair, should take appropriate precautions to prevent the on-site repair of replacement parts before entering the mechanical contaminated dust and other impurities.
