Mining Slurry Pump Manufacturers Trend Report

If the Slurry Pump is found to be blocked during use, how to solve it is that many customers think that this is a relatively complicated problem. Once this blockage problem is not handled properly, it will easily cause damage to the equipment, thereby affecting the efficiency of use. Therefore, everyone should pay special attention to the clogging problem of the slurry pump. In fact, if you grasp the following points, you can easily solve the problem.

(1) The solid and hard deposits in the volute of the horizontal slurry pump make it silted up, and measures to remove the silt can be taken.

(2) If the axis of the shaft and the feeding box are different, the main reason is that the machining error is large and the installation is incorrect. Care should be taken to check that the installation is correct after installation. If the sealing water ring is seriously worn, it needs to be replaced with a new water ring. If the sealing water pipe is blocked, the sealing water cannot enter the middle of the packing, which will cause the packing to wear quickly and lead to leakage. The blocked water pipe should be dredged to keep the sealing water clean.

(3) If the impeller or the water inlet and outlet pipelines are blocked, the impeller or pipeline can be cleaned. If the impeller is seriously worn, it should be replaced. If the packing port leaks, the packing should be pressed tightly. If the conveying height is too high, the loss resistance in the pipe is too large, so reduce the conveying height or reduce the resistance.

The horizontal slurry pump should be regularly maintained during its use, including dredging. This can effectively avoid the problem of slurry pump blockage. If you encounter these problems in the later use of the slurry pump, you can follow the steps above. resolve.

The main part of the sand gravel pump accessories is also called the overflow part. Including pump cover, impeller, volute, front guard, rear guard, etc.

This series of pumps are horizontal, single pump casing centrifugal pumps. The pump body and pump cover are clamped by special clamps, and the outlet direction of the pump can be in any position of 360 degrees, which is easy to install and use.

The shaft seals of the sand gravel pump include packing seals, impeller seals and mechanical seals.

Bearing assembly: The bearing assembly of the sand gravel pump adopts a cylindrical structure, which is convenient to adjust the gap between the impeller and the pump body, and can be removed as a whole during maintenance. Bearings are grease lubricated.

Transmission mode of sand gravel pump: there are mainly V-shaped V-belt transmission, elastic coupling transmission, gear reduction box transmission, hydraulic coupling transmission, frequency conversion drive device, thyristor speed regulation, etc.

The overall performance of the sand gravel pump: the material of the overflow parts is made of high-hardness wear-resistant alloy cast iron. The pump has a wide flow channel, good cavitation performance, high efficiency and wear resistance. Various speeds and variants are used to allow the pump to operate under design conditions. It has a long service life and high operating efficiency, and can meet many kinds of harsh conveying conditions

Today we will understand the precautions of forth pump operation. CNSEM ®  will give you a brief introduction. Let's have a look together.

When the forh pump is running, it is necessary to check the operation of the bearing assembly regularly. If the bearing is heated during open operation, it is necessary to stop the pump and wait for the pump shaft to cool down before running again. If the temperature of the bearing is still too high, and the temperature continues to rise, it is necessary to disassemble the bearing assembly of the pump shaft to check what the reason is.

General bearing heating is mostly caused by too much grease, or by magazines in grease. The amount of bearing grease should be appropriate, but also need to ensure cleanliness, and grease should be added regularly.

The performance of the forth pump deteriorates with the increase of the wear interval of the impeller and the protection plate, and the efficiency decreases. Therefore, the impeller should be adjusted upward in time, so as to maintain a certain interval so that the forth pump can maintain high efficiency operation.

When the forth pump wear cannot meet the needs of the system, it should be replaced in time.

Are you looking for a reliable, efficient pump to transport dirt and other solids? Slurry pumps may be just the solution! With their ability to move large amounts of abrasive material at high speeds, slurry pumps can often outperform traditional pump systems. But how exactly do they work? In this article, we’ll explore the inner workings of slurry pumps so that you have all the tools necessary to make an informed decision. Ready to dive in? Let’s go! 

However, Before diving in first, let’s know what a slurry pump is, 

What Is a Slurry Pump? 

A slurry pump is a type of centrifugal pump designed to move Suspended solids, such as particles of sand and gravel, through a liquid medium. The design of the pump allows it to increase pressure so that the slurry can be moved large distances or up vertical inclines. Slurry pumps are typically used in dredging, mining and mineral processing applications. Additionally, they are commonly used in wastewater treatment operations. 

Essential Components of a Slurry Pump 

The essential components of a slurry pump include the volute or casing, impeller, shaft, sealing mechanism, motor or engine, and base plate. The volute is a curved funnel that collects and directs the flow of the pumped material. This part is typically made of hard-wearing materials such as chrome alloy steel to withstand the slurry’s high pressures and abrasive nature. 

Impeller 

The impeller is a rotating component that pushes the liquid forward and out of the volute. The component can be made from hard-wearing materials like chrome alloy steel or softer materials such as flexible rubber to help reduce wear and tear on the other pump parts. 

Shaft 

The shaft is a metal rod that connects the impeller to the motor or engine. This component is typically made of high-strength materials such as stainless steel to withstand the high stresses and torque generated by a powerful slurry pump. 

Sealing Mechanism 

The sealing mechanism prevents leakage of the pumped material around the impeller. It typically consists of a series of mechanical or hydraulic seals designed to move flexibly with the flow of the pumped material. This helps prevent damage and wear on the seals, which can be very costly to replace. 

Motor 

The motor or engine powering the slurry pump is typically located at the pump’s base. Depending on the application’s needs, it can be a traditional electric motor or an internal combustion engine. 

Overall, a slurry pump is a highly specialized piece of equipment that uses a variety of components to effectively move and process large volumes of liquid, solids, and other materials. 

Construction of Slurry Pump 

A slurry pump is made up of different parts. It has an inlet volute that helps direct the liquid and particles into the impeller, which makes them move through a discharge pipe. A shaft seal and bearing housing stop fluid from leaking out, and a casing helps guide the flow of particles and liquids. The impeller uses centrifugal force to make it work. 

How Does a Slurry Pump Work? 

A slurry pump is a type of centrifugal pump that uses the kinetic energy of a rotating impeller to increase the pressure and flow rate of a fluid. The liquid enters the eye or inlet of the impeller and then accelerates as it passes through each stage. In doing so, it becomes increasingly pressurized and is forced out by centrifugal action at high velocity from the volute discharge outlet. This pressure forces solids particles suspended in the liquid to be drawn into and carried along with its flow stream, thus producing an efficient pumping action for abrasive slurries. 

The Benefits Of Using a Slurry Pump 

There are so many benefits to using a slurry pump. Some of the benefits of using a slurry pump include the following: 

Increased efficiency and reliability in pumping thick liquids. 

Reduced downtime due to fewer clogs and blockages. 

Lower maintenance costs due to fewer parts that need replacing or repairing. 

Greater control over the flow rate of the liquid being pumped. 

Enhanced safety as they are designed with built-in safeguards against pressure overloads. 

Types Of Slurry Pumps 

Slurry pumps move viscous, abrasive and high-density mixtures such as slurries in various industrial and mining applications. Depending on the application, there are several types of slurry pumps available. 

Centrifugal Slurry Pumps 

These Centrifugal slurry pumps rely on centrifugal force to move the slurry through the pump. The rotating impellers in these pumps create pressure that forces the mixture to move outwards and into the discharge pipe. 

Diaphragm Slurry Pumps 

These pumps use a diaphragm to separate the moving fluidly from the discharge pipe. This allows the slurry to be pumped without impacting the pump’s moving parts. 

Other Slurry Pumps 

Other slurry pumps use different mechanisms to move the slurry mixture through the pump and out to the discharge pipe. Whatever type of slurry pump you use,it is essential to understand how it works to maintain and troubleshoot any issues that may arise.

To Sum Up
