Sand/ Sludge/ Slurry
Oil and gas drilling is tough on equipment, particularly the drill bit, which needs almost constant attention to keep the rig operating properly. Injecting drilling mud into the wellbore is among the most important techniques crews have to keep the drill bit and the rest of the operation on track. Drilling mud includes varying combinations of bentonite, barite, fresh- or salt-water, oil or other synthetic additives. This depends on the type of formation you’re drilling and the restrictions imposed by environmental regulations.
Coal-mining operators rely on submersible slurry pumps to handle punishing conditions. Among the harshest environments for pumps, coal slurry quickly abrades their metal components. Inferior pumps lower mine output and increase operating costs. How can you extend pump lifespan and raise job productivity? Below we discuss the most cost-effective wastewater pumping equipment for coal-mining applications.Coal-Mining Pump Issues That Increase Your Costs
There are three coal-mining issues that plague slurry pumps and shorten their lifespans.Abrasive Solids
Coal itself is a highly abrasive material. A coal slurry is a muddy, acidic mixture of water, coal chunks, coal fines, dust, dirt and rocks. Coal fines are coal particle size usually less than one-sixteenth of an inch. These are especially abrasive to a pump’s internal components. These materials combined wreak internal havoc on pumps, causing clogs and failures.
