Product details

NL sewage mud pump | stainless steel mud pump-Introduction
Mud pump is a mechanical device that delivers flushing fluids such as mud or water to the borehole during the drilling process. Mud pump is an important component of drilling machinery equipment. Its main function is to inject mud into the wellbore with the drill bit during the drilling process, cooling the drill bit, cleaning the drilling tools, fixing the wellbore, driving the drilling, and bringing back the rock debris after drilling to the surface. In commonly used positive circulation drilling, the mud pump sends the surface flushing medium - water, mud, or polymer flushing fluid - directly to the bottom of the drill bit through a high-pressure hose, faucet, and drill string center hole under a certain pressure, in order to cool the drill bit, remove the cut rock debris, and transport it to the surface. Commonly used

The NL sewage cement slurry pump is a single-stage single suction vertical centrifugal pump, consisting of main components such as volute, impeller, pump seat, pump casing, support cylinder, motor seat, and electric motor. The snail shell, pump seat, motor seat, and impeller nut are cast from pig iron, with good corrosion resistance and convenient processing technology. The impeller consists of three single chord curved blades, which are semi enclosed and made of malleable cast iron, resulting in high strength and corrosion resistance; Easy processing, good passability, and high efficiency. In order to reduce weight and cutting volume, the pump shaft is made of carbon steel cold drawn round steel. The mud pump seat is equipped with four skeleton oil seals and shaft sleeves to prevent shaft wear and extend the shaft. This mud pump can be used vertically or obliquely, with a small footprint. The volute shell needs to be buried in the working medium for easy start-up and does not require water intake. The rotation direction should be clockwise when viewed from the tail of the motor. There are various specifications for the length of the switchboard, so that users can choose according to their specific needs.

NL sewage mud pump | stainless steel mud pump-Main purpose:
① NL type mud pump is used in mining, papermaking, printing and dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petroleum, chemical industry, farms, salt fields, iodine fields, dyeing, brewing, food, fertilizer, coking plants, construction, marble plants, gold mines, mud, quicksand, mud ponds, sewage ponds, polluted liquids for conveying and absorbing thick slurry, loading and suspended solids in sewage operations. It can also be used for coal mine drainage and fluids containing mud blocks.
② If the mud pump is combined with a high-pressure water pump and water to form a hydraulic mechanized earthwork unit, it can be used for excavation and transportation of small water conservancy projects such as land leveling, dredging and chiseling of rivers and ponds, as well as urban air defense projects.
③ Fish farming is used for carrying water to clear ponds, increasing oxygen in fish ponds, etc.
