Some manufacturers will market now false submersible drilling rig prices, under normal circumstances, offer submersible drilling rig should be cost plus profit, the profit is generally maintained at about 20%, and now imports roughly the same cost submersible drilling rig equipment on the market rig models, so you can target some of the data provided by the manufacturer of submersible drilling rig submersible drilling rig at the time of purchase and inventory data after you, you can choose The psychology of submersible drilling rig to assess directly. Some manufacturers offer submersible drilling rig will be high, this time to fully consider submersible drilling rig equipment performance meets the manufacturer's price, if lower price, they should note that there may be a price misunderstanding bridge rig models, be careful rig models, a sub-price goods, so be sure to get enough thick product, let submersible drilling rig stable operation, bring more benefits. Some manufacturers are only responsible for the sales, not responsible for the installation, this time to pay special inquiry, so the customer is submersible drilling rig manufacturers signed the purchase contract, must be especially noticed this one, clearly this detail. Cautious buying DTH drilling opportunities for our save a lot of trouble. 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 between the mating surfaces of the exploration rig mechanical model, the harm is great, not only out of the block relative motion, accelerated wear of parts, and will scratch the mating surfaces, destroy the lubricant film, so Parts 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%. Thus, for work in harsh environments, the conditions for complex engineering machinery spaces, one should use high-quality, matching parts and lubricants, greases, blocking the source of harmful impurities; two to do the job 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.
