Introduction to slurry pump

Slurry pump is a unique pump used to treat slurry. In contrast to the water pump, the slurry pump is a heavy-duty structure and bears more wear. Technically speaking, the slurry pump is a heavy-duty and robust version of the centrifugal pump, which can handle abrasive and arduous tasks. Compared with other pumps, the design and construction of slurry pump are much simpler. Although the design of slurry pump is simple, it has high durability and strength in harsh environment. These forms of pumps play a vital role in various industries. They are the basis of all wet processes.

What is pulp? In principle, it is possible to transport any solid by hydraulic power. However, the size and shape of particles may be limiting factors, depending on whether they can pass through the pump pipe without blockage. There are four main categories under the general category of slurry, which can help you determine the suitable type of slurry pump to meet your needs and business needs.

Type 1: mild abrasive

Type 2: Micro Abrasive

Type 3: strong abrasive

Type 4: high strength abrasive

If you want to move high abrasive type 4 mud, the ideal choice is the oil sand pump. The ability to handle a large amount of mud and enhanced bearing capacity are the advantages of slurry pump. They are specially designed for hydraulic transport of large granular solids and ensure better wear performance under harsh conditions.

Four types of centrifugal slurry pumps

Although centrifugal slurry pumps are famous for their use in oil sands, many of them have other uses. Water transport pumps are widely used because the moving mud is transported by water. The ideal way to use these slurry pumps is to use water. They are mainly used in industries requiring dredging. Tailings delivery pump is the perfect type of pump for conveying tailings or finer abrasive materials produced from hard rock mining, such as debris of mud and ore, and related chemicals used in the mining process. Cyclone pump feed pumps, such as tailings pumps, are also used in hard rock mining and can be compared with hydraulic transfer pumps because they are also used in dredging operations. These forms of pumps are used for all stages of peeling and separating solids according to particle size. The slurry pump can also be used to transport foam, but the air trapped in foam will have a negative impact on the performance of the pump. Despite the solid structure of the slurry pump, the air in the foam will damage the slurry pump and shorten its service life. However, the wear of the centrifugal pump can be reduced by taking appropriate precautions.

working principle

First describe the relationship between centrifugal pump and slurry pump, and then the principle of slurry pump will be clear. The centrifugal concept is based on the principle of pump. There are many kinds of pumps, which can be divided into dozens of categories according to different angles. Centrifugal pump is divided from the working principle. It is a process of pressurizing the conveying medium through the action of centrifugal force. In addition, there are also common types, including screw principle and plunger principle, which can be divided into pumps different from centrifugal principle. After completing the concepts of centrifugal pump and slurry pump, the slurry pump is divided from another perspective, that is, from the perspective of conveying medium. As the name suggests, the slurry pump conveys a mixture of solid particles containing slag and water. But in principle, the slurry pump belongs to a kind of centrifugal pump. In this way, the two concepts are clear.

The main working parts of centrifugal pump are impeller and shell. The impeller device in the shell is located on the shaft and connected with the prime mover to form a whole. When the prime mover drives the impeller to rotate, the blades in the impeller force the fluid to rotate, that is, the blades do work to the fluid along its moving direction, so as to increase the pressure potential energy and kinetic energy of the fluid. At the same time, under the action of inertial force, the fluid flows from the center of the impeller to the edge of the impeller, flows out of the impeller at high speed, enters the extrusion chamber, and then is discharged through the diffuser. This process is called hydraulic process. At the same time, because the fluid in the center of the impeller flows to the edge, a low-pressure area is formed in the center of the impeller. When there is enough vacuum, the fluid enters the impeller through the suction chamber under the action of suction end pressure (generally atmospheric pressure). This process is called water absorption process. Due to the continuous rotation of the impeller, the fluid will be continuously discharged and inhaled to form a continuous work.

The working process of centrifugal pump (including slurry pump) is actually a process of energy transfer and transformation. It transfers the mechanical energy of the high-speed rotation of the motor through the blades of the pump and converts it into the pressure energy and kinetic energy of the pumped fluid.

The structure of slurry pump is simple and firm. The working principle of slurry pump is much simpler and easy to follow than other pumps. The mud enters the pump through the rotating impeller, which makes a circular motion. Then the slurry is pushed outward by centrifugal force and moves between the blades of the impeller. The mud accelerated as it hit the edge of the impeller. Its high-speed energy is converted into pressure energy in the shell. With the help of centrifugal force, the pump increases the pressure of liquid and solid particles, converts electric energy into kinetic energy and pumps slurry. The system can easily pump light slurry without much trouble, and maintain the benefits of its industrial application of maintaining free slurry pump
