The hot plating wire uses zinc-free slag to add hot melt zinc and galvanize, which avoids the traditional heating process and radiates the surface 1653 of zinc liquid surface 4102 to the hot melt zinc, reducing the high temperature oxidation on the surface of zinc liquid. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, which reduces the heat radiation of the zinc liquid surface.

The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violent”, or the cage under the “destruction” will occur welding or plastic crack off.

- The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge line.
- Rubber Lined Slurry Pump
- As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.
- Heavy-Duty Slurry Pump
- Slurry pumps with rubber lining are the ideal pump for the mineral sand industry. They have a special rubber lining that makes them heavy duty pumps capable of withstanding high levels of abrasion.
- In a subsea installation, the slurry pump runs directly in the slurry and does not require a support structure, which means it is flexible and easy to install. If possible, the catch basin should be equipped with sloping walls to allow sediment to slide down into the area directly below the pump inlet. Agitators should be used when the liquid contains large amounts of solids and has a high particle density. Freestanding or side-mounted (submersible) mixers are an excellent choice for resuspended solids, especially if the catch basin is large or does not have sloping walls.
- If you have experience pumping slurries, you know it's not an easy task. Slurries are heavy and difficult to pump. They cause excessive wear on pumps and their components and are known to clog suction and discharge lines if not moving fast enough. Most importantly, it’s a challenge to make slurry pumps last for a reasonable amount of time. But, there are a few things you can do to extend the life of your slurry pump and make pumping slurry less of a challenge.

- How to Choose a Dredging Pump or Slurry Pump
- A dredge pump contains a pump casing and an impeller. The impeller is mounted in the pump casing and connected to the drive motor via a gearbox and shaft. The front part of the pump casing is sealed with a suction cover and connected directly to the suction pipe of the dredger. The discharge port of the dredge pump is located near the top of the dredge pump and is connected to a separate discharge line.

- WL Series Light-duty pumps are cantilevered, horizontal centrifugal slurry pumps. They are suitable for delivering low density slurries for metallurgical, mining, coal and building material departments. The shaft seal adopts both gland seal and centrifugal seal.

- A >dredge pump is a horizontal centrifugal pump that is the heart of a dredger. It is designed to handle suspended abrasive granular materials and solids of limited size. Without a dredge pump, a stranded dredger would not be able to deliver mud.
- Another way of classifying the type of slurry pump installation is dry installation or wet installation. Dry installation pumps have the hydraulic end and drive located outside the liquid, whereas wet installation pumps (such as submersible pumps) operate within a catch basin or slurry. Submersible pumps do not require much support structure and therefore do not take up much space. Depending on the type of operation and installation required, the preferred method of pump installation is determined.

- If youve ever pumped a slurry, you know it can be one of the most challenging fluids to work with. It is abrasive, viscous, sometimes corrosive, and contains a lot of solids. Theres no doubt that the slurry on the pump is hard. But the more you know about whats being pumped, the better your pump selection will be, resulting in longer mean time between failures.xa0Next, the , slurry pump supplier, will share the following content with you.
- All products are mainly supplied to environmental protection, wastewater treatment, urban water supply and drainage, mine, metallurgy, coal, petrochemical, building material, thermal power FGD, river dredging, tailing disposal and other fields.
- Hydrostatic head - i.e. the height to which the slurry must be lifted in the piping system.
- Adapting a pump to its precise application - be it pulp and paper, gas and oil, mining or industrial applications - will have a direct impact on its service life. That's why our bespoke pumps have the unique advantage of interchangeable components. These components include slurry valves, which can be replaced every 6 months as a preventive measure and every 12 months for regular maintenance, depending on the application.
- The concentration of solids in the slurry - measured as a percentage of the total volume.

- If centrifugal, are the impellers of the right design and material?
- 3.Basic pump components such as impeller size and design, materials of construction and discharge configuration must be considered to ensure that the pump can withstand the wear and tear caused by abrasive slurries. Slurry pumps are typically larger in size compared to low viscosity liquid pumps and often require more horsepower to operate due to their lower efficiency. Bearings and shafts must also be more robust and durable.
- What style of pump is suitable?
- Magnetite mixing
- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.
- Other manufacturers looking for differentiation, if not the end result, may choose to add a small part to their pump assembly in the description, thus allowing in-line adjustment of the wear ring in the suction side lining assembly.
- The dredge pump is designed to draw sediment, debris and other hazardous materials from the surface layer into the suction pipe and transport the material through the pipe to the discharge site. The pump must be able to handle common solid debris of various sizes that can pass through the pump, thus minimizing the downtime required for cleaning.

- How to choose a slurry pump?
- Underwater installation
- The rule of thumb for setting the water pressure is the same when using the pack box, whether flushing. Mud pump shut-off pressure plus 10% or plus 20 psi, whichever is greater. However, the flow rate is set differently.
- Keep in mind that slurry pumps are designed to adapt to specific pumping conditions. Pumps used in the cement industry handle most fine particles at low pressures, so the casing can be of lightweight construction. In rock pumping, the casing and impeller must be able to resist slamming, so they must be built thick and strong.
- Process speed doesn’t have anything to do with choosing slurry pump impeller, but it does have an effect on the life of slurry pump impeller. It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.
- Floor drainage
- - Reduced space requirements - Since submersible slurry pumps operate directly in the slurry, they do not require any additional support structures.
- Fine-grained sand can be extremely abrasive and typically wears slurry pumps quickly. Characteristics of coarse aggregates that can affect pump performance are size, shape and surface texture, as well as gradual changes in particle size, while fine materials can create excessive friction in the pipe.
- Many types of pumps are used for pumping slurries.The centrifugal slurry pump uses the centrifugal force generated by a rotating impeller to impact kinetic energy to the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.
