Slurry pump and mud pump are two concepts that are often confused. These two types of pumps both transport slurry and do not transport pure liquid, and they are crossed in the application. Today, I will introduce in detail the difference between a slurry pump and a mud pump.
Definition of Two Types of Pumps:
A mud pump is also a general concept of a broad pump. Different regions and habits will eventually involve different pump types. The mud pump described in this entry is a pump type in most senses: the field of oil drilling The applied mud pump. In fact, some non-clean water pumps and mud pumps, such as sewage pumps, slurry pumps, etc., are also commonly called when they are called. This entry describes the mud pump in the field of drilling to the reader.
The slurry pump belongs to the centrifugal pump in terms of working principle. Conceptually, it refers to a machine that increases the energy of the solid and liquid mixed medium through the action of centrifugal force (the rotation of the impeller of the pump), and converts electrical energy into the kinetic energy of the medium. Potential energy device. Mainly used in: mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum and other industries. The name of the slurry pump is a centrifugal pump from the perspective of conveying medium. In addition, the slurry pump can be divided into different types from different angles. In addition to pumping water, the water pump can also pump gas, solid, and solid-liquid mixture—mineral powder slurry! The electricity consumption of water pumps accounts for a large proportion of the country's total electricity, and the energy saving of water pumps has an important impact on the national economy. The slurry pump not only saves 4%-8% energy than similar products, but also contributes to the escape of the atmosphere from the "magic claws" of smog.
The Difference Between the Two Pumps
Mud pump features and uses:
1. It can transport high concentration and high viscosity <10000PaS and suspended slurry-containing particles.
2. The conveying liquid flow is stable, without overcurrent, pulsation, stirring, and shearing of the slurry.
3. The discharge pressure has nothing to do with the rotation speed, and the low flow rate can maintain a high discharge pressure.
4. The flow is proportional to the speed, and the flow can be adjusted through the speed change mechanism or the speed regulating motor.
5. The self-priming ability is strong, and the liquid can be directly pumped without installing a bottom valve.
6. The pump can be reversed, and the liquid flow direction is changed by the rotation direction of the pump, which is suitable for occasions where the pipeline needs to be flushed in the reverse direction.
7. Smooth operation, low vibration, and low noise.
8. Simple structure, easy disassembly, and maintenance.
It is a machine that transports flushing fluids such as mud or water to the borehole during the drilling process. The mud pump is an important part of the drilling machinery and equipment. Its main function is to inject the mud into the well with the drill bit during the drilling process. The mud pump is of piston type or plunger type. The crankshaft of the pump is driven by the power machine to rotate, and the crankshaft drives the piston or plunger to reciprocate in the pump cylinder through the crosshead. Under the alternate action of the suction and discharge valves, the purpose of pressurizing and circulating the flushing liquid is realized.
Slurry Pump Features and Uses
Slurry pumps can be widely used in mining, electric power, metallurgy, coal, environmental protection, and other industries to transport slurries containing abrasive solid particles. Such as slurry transportation in metallurgical dressing plants, hydraulic ash removal in thermal power plants, coal slurry and heavy medium transportation in coal washing plants, river dredging, and river dredging. In the chemical industry, some corrosive slurries containing crystals can also be transported. First of all, about 80% of the applications in concentrators are used in concentrators in the mining industry.
Due to the harsh conditions of ore primary selection, the service life of the slurry pump is generally low in this section. Of course, different ores have different abrasive properties. For example, the relative abrasiveness of the concentrate conveying and other sections are reduced, and the overall service life of the pump is longer. Therefore, when the general user often asks about the service life of the supplier's products during the procurement process, strictly speaking, any manufacturer will not promise an accurate service life for the user without any basis, because of the service life of the overcurrent components The service life of (wear-resistant and corrosion-resistant parts) depends on many different factors. The diversity and complexity of working conditions lead to differences in the service life of materials of the same quality.
