well known in the fertilizer industry. John Blue/Thurston also offers a pressure reducing pump. No beat exchanger or super cooler is used in the direct injection pressure increasing system. E-6:0.1236 gallons per stroke, 350 rpm, Range @ 8 mph, 40 to 195 lbs. N @ 52.5 ft. E-6:...
All the control rules for the lake source, pipe 330 and pump 335, were removed. In addition, pipe 330 was kept closed. This means that these two raw sources only supply water through pumps 10 and 335, which are controlled by the agent, rather than supply water under specific control rule...
Furthermore, this study demonstrates that the biotechnological potential of the well-studied fungal genus Aspergillus is far from being exhausted, and in particular, isolates from extreme environments, such as the Arctic deep sea, are a promising source of new antimicrobial metabolites. The MN-based...
The inner recharge wells were used to prevent the accumulation of calcium carbonate in the pipe mouth from blocking. The seepage field formed by the inner recharging wells was used to continuously drive the bacteria and cement fluid injected from outer recharge well to prevent the bacteria and ...
The fractured granite reservoir is well developed in Yongle block, which leads to severe drilling fluid loss-circulation. To solve the technical problem of both plugging and reservoir protection, on the basis of comprehensive literature research and laboratory tests at home and abroad, a polymer with...
(CCK8, MCE, Monmouth Junction, NJ, USA) was added in each well and cultured for 2 h. The absorbance at 450 nm was measured with a microplate reader (Tecan Sunrise, TECAN Deutschland GmbH, Crailsheim, Germany), and cell viability was calculated according to the manufacturer’s instructions....
In this study, a hydraulic pressure test was carried out with the rock cabin and drill pipe cabin, and the pressure pump of a Sichuan jet was used for pressure testing, as shown in Figure 9. Considering the influence of temperature and pressure on the cabin body, the minimum test pressure...
The data transmission between the inlet section of the mining pump and the impeller, as well as between the impeller and the guide vane, is performed through an interface. For the setting of boundary conditions for solid particles, escape boundary conditions are used at the inlet and outlet of...
a transparent acrylic pipe, measuring one meter in length, is affixed to the input and output ends of the impeller. This configuration provides a visual window into the cavitation process, enabling researchers to closely examine the intricate details of these occurrences. In addition, an acceleromete...
