MUD PUMP is also a popular concept of a wide pump. Different regions, habits, and ultimately pump types are not the same. : The applied mud pump in the field of petroleum drilling. In fact, some non -water pumps and mud pumps such as sewage pumps, slurry pumps are also universal on the call method. This entry explained to readers the mud pump in the drilling field.
Product introduction
The mud pump refers to the machine that sends mud or water such as mud or water such as the drilling process during the drilling process. The mud pump is an important part of the drilling equipment.
In the commonly used positive cycle drilling, it is to rinse the surface -clean water, mud, or polymer rinse of the surface under a certain pressure. The purpose of cooling drills, removing and transporting the cut rock chips to the surface.
The commonly used mud pump is a piston or a plunger. The crankshaft rotation of the pump is driven by the power motor. The crankshaft will drive the piston or the plunger through the cross head or the plunger in the pump cylinder. Under the alternation of inhalation and discharge valves, the purpose of pressure delivery and cyclic flushing fluid is achieved.
Classification
Act
Single -action mud pump
In a cycle of the piston movement, only one drainage action is completed
Double -action mud pump
Complete two drainage movements in a cycle of piston reciprocating movement
Number of tanks
If the number of cylinders in the pump is classified, there are types of single cylinder, double -cylinder, three -cylinder, and five -cylinder.
Performance
Two main parameters of mud pump performance are displacement and pressure.
Displacement
The displacement is calculated based on several liters per minute. It is related to the diameter of the drilling and the required flushing liquid from the bottom of the hole. The larger the pore diameter, the greater the required displacement. The upward speed of the rinse solution is required to cut off the rock chips and rock powder from the bottom of the drill head away from the bottom of the hole, and bring them to the surface reliably. When the geological rock heart drill, the upward speed is generally about 0.4 to 1.0 meters/min.
pressure
The pressure of the pump depends on the depth of the drill, the resistance of the channel passed by the rinse solution, and the nature of the flushing fluid that is transported. The deeper the drill, the greater the resistance of the pipeline, and the higher the pressure you need.
With the diameter and depth of drilling, the displacement of the pump is required to be adjusted at any time. There is a gearbox or a hydraulic motor in the pump mechanism to adjust its speed to achieve the purpose of changing displacement. In order to accurately grasp the pressure and displacement of the pump, the traffic meter and pressure gauge should be installed on the mud pump to make the drill personnel understand the transportation of the pump at any time. ACCIDENT.
Features
- Transfer high concentration and high viscosity <10000PAS and suspended slurry containing particles.
- The phenomenon of stable flowing liquid flowing, no overcurrent, pulse and stirring, and shearing slurry phenomenon.
- The excreted pressure has nothing to do with the speed, and the low flow can also maintain high excretion of pressure.
- The flow is directly proportional to the speed, and the flow adjustment can be achieved through the transmission mechanism or the speed adjustment motor.
- Strong self -suction ability, you can directly suck the liquid without using the bottom valve.
- Pumps can be reversed. The liquid flow is changed from the rotation direction of the pump. It is suitable for the occasion where the pipeline needs to be washed towards rinse.
7, stable operation, small vibration, small noise. - Simple structure and convenient disassembly and maintenance.
The I-1B thick pulp pump is widely used in chemical, pharmaceutical, brewing, papermaking, food and other units.
