Mud Pump is also a popular concept of a wide range of pumps. Different regions, habits, and ultimately the pump type will not be the same. The mud pump described in this entry is a pump type in most sense: Applied mud pumps in the field of oil drilling. In fact, some non-clean water pumps and mud pumps, such as sewage pumps and slurry pumps, are also commonly used when they are called.
Mud pump refers to a machine that transports mud or water and other flushing fluid into the borehole during drilling. Mud pumps are an important part of drilling equipment.
In the commonly used positive circulation drilling, it is to send the surface flushing medium—clear water, mud or polymer rinsing liquid to the bottom end of the drill bit through a high-pressure hose, faucet and drill rod center hole under a certain pressure. Cool the drill bit, remove the cut debris and transport it to the surface.
The commonly used mud pump is a piston type or a plunger type, and the crankshaft of the pump is driven by the power machine, and the crankshaft passes the crosshead to drive the piston or the plunger to reciprocate in the pump cylinder. Under the alternating action of the suction and discharge valves, the purpose of pumping and circulating the flushing liquid is achieved.
BW Series Mud Pumps are mainly used for supplying flushing fluid to the borehole in core, geothermal, water resource, shallow oil, CBM and other drilling process. The fluid can be divided into mud, water, etc. They also can be used as transfer pumps of the above-mentioned medium. This series of mud pumps are with simple structure and easy to maintain and operate. Piston, lip-shaped and self-sealing type, is made of rubber or PTFE and nylon pads, equipped with shock-resistant pressure gauge, necessary spare parts and special tools. Bi-metal liner can be used to extend service life of pump greatly.
NB Series Mud pumps are mainly used for the core, coal geology, metallurgy geology, hydrogeology engineering hole drilling fluid is supplied, flushing fluid can be divided into mud, water, etc., may be used as the above medium pump.
Structural features: The mud pump is crank structure, horizontal triplex single acting piston pump, the piston is self-sealing lip, made of rubber or PTFE and nylon protective pads pressed, the pump adopts auto gearbox, variable five kinds of flow, the pump is compact, high efficiency, durable, safe, reliable, easy maintenance, low maintenance costs.
ZB Series grouting pumps are mainly used for kinds of weak corrosivity viscous and nonviscous liquid grouting(such as water, mud), especially for vertical shaft working face grouting, goaf filling, coal mine water inrush governance and so on.
The pump is triplex single-acting plunger high pressure pump, fitted with international first-class gearbox, which is of features like compact structure, multistage speed regulation, realizing different flow rate and pressure, meeting the grouting requirements of different formation. Electric motor drives triplex pump through transmission system. It has many advantages, like convenient adjustment for pressure and flow rate, long service life and so on.
3NB & 5NB Series Mud Pumps are mainly used for oil, water well, geothermy, CBM, shale gas, coalfield exploration, freezing well as well as well other drilling ,well cementation, work-over and other operations in industrial and mining enterprises. It is used for transferring mud, clay gum, mortar and other medium to the borehole. The pump adopts international advanced technology. It is characterized by advanced structure, reliable operation, good suction performance, long service life of wearing parts, easy for maintenance and repairing and so on.
F Series Mud Pumps are mainly used in oil field and geological prospecting for well drilling, well work-over, cementing, water shut off, water flooding and sending mud, clay, grout and so on.
