Overview of Mud Pump Products

A mud pump is a machine that delivers a rinsing fluid such as mud or water to a borehole during a drilling process. Mud pump is an important part of drilling machinery equipment. Its main function is to drill the mud with the drill bit and inject it downhole during the drilling process, to cool the drill bit, clean the drill tool, fix the shaft wall, drive the drill, and bring the rock debris back to the ground after drilling. In the commonly used positive circulation drilling, the slurry pump directly sends the surface flushing medium-water, mud or polymer washing fluid through the center hole of the high pressure hose, the faucet and the drill string under the certain pressure, to directly feed the bottom end of the drill bit, so as to achieve Cools the drill bit, removes the cut rock debris and transports it to the surface. The commonly used mud pump is piston type or plunger type. The power machine drives the crankshaft of the pump to rotate. The crankshaft drives the piston or plunger through the crosshead to reciprocate in the pump cylinder. With the alternating action of suction and discharge valves, the purpose of pressure feed and circulating rinse liquids is achieved.

Slurry Pump Performance Parameters The two main parameters of mud pump performance are displacement and pressure. Displacement is calculated as the number of liters per minute, which is related to the diameter of the borehole and the required speed of the flushing fluid from the bottom of the hole. The larger the bore diameter, the greater the required displacement. It is required that the speed of return of the rinsing liquid can promptly remove rock debris and rock powder cut by the drill bit from the bottom of the hole and reliably carry it to the surface. In geological core drilling, the speed is generally about 0.4 to 1 m/min. The pressure of the pump depends on the depth of the borehole, the resistance of the passage through which the rinsing fluid passes, and the nature of the rinsing fluid delivered. The deeper the drilling, the greater the resistance of the pipeline and the higher the pressure required. With the change of drilling diameter and depth, the required pump displacement can also be adjusted at any time. In the pump mechanism there is a gearbox or a hydraulic motor to adjust its speed to achieve the purpose of changing the displacement. In order to accurately grasp the pressure and displacement of the pump, the flowmeter and pressure gauge shall be installed on the mud pump to make the drilling personnel understand the operation of the pump at any time, and at the same time, to judge whether the condition in the hole is normal through the pressure change to prevent accidents in the hole. .

Mud pump classification Mud pump is divided into single-action and double-acting types. The single-acting mud pump only completes one suction and drainage operation in one cycle of piston reciprocating motion. The double acting mud pump completes two suction and drainage actions each time it reciprocates. According to the number of mud pump cylinders, there are three types of single-cylinder, twin-cylinder and three-cylinder.

NL sewage slurry pump is a single-stage single-suction vertical centrifugal pump, the main components are volute, impeller, pump seat, pump casing, support cylinder, motor seat, motor and other components. The volute, pump seat, motor seat and impeller nut are pig iron castings with good corrosion resistance and convenient processing technology. The impeller is a three single-chord curved blade. Semi-closed impeller is selected. The malleable cast iron is used. Therefore, it has high strength and corrosion resistance. It is easy to process, has good passability and high efficiency. In order to reduce weight and reduce the amount of turning, the pump shaft is made of high-quality carbon steel cold drawing steel. Four skeleton oil seals and bushings are installed in the mud pump seat to prevent shaft wear and extend the service life of the shaft. The mud pump can be used vertically or obliquely, and has a small footprint. The volute needs to be buried in the working medium and is easy to start without diversion. The direction of rotation should be viewed clockwise from the rear of the motor. The length of the switchboard is equipped with various specifications so that the unit can be selected according to the purpose of use.

The main purpose of the mud pump 1NL type mud pump is used in mining, papermaking, printing and dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petroleum, chemical, farm, salt, iodine, dyeing, brewing, food, fertilizer, Coking plant, building, marble factory, gold mine, mud, quicksand, mud pond, filthy pond, polluted water sent to thick liquid slurry, loading material and suspended material can also be used as coal mine drainage and mud containing fluid.

2 If the mud pump is combined with a high pressure water pump and a water gun to form a hydraulic mechanized earthwork unit, it can be used as a land leveling, river channel and pond dredging, mining and other small water conservancy projects, as well as urban air defense projects. The following works.

3 Fish farming is used as a water clearing pond and fish pond oxygenation.
