The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

- The frame plate for WAJ series pumps has interchangeable hard metal or pressure moulded elastomer liners. The impellers are made of pressure moulded elastomer liners.The shaft seals for WAJ series can be packing seal, centrifugal seal or mechanical seal.
- When slurry pump working, which is the motor drives the impeller rotation. That is the impeller on the slurry work which increases the kinetic energy of the slurry. At the same time, the slurry flows to the edge of the impeller due to inertia and is discharged from the discharge pipe at a high speed.
- Is the discharge configuration suitable for abrasive slurries?
- 1. The two types of pumps are all centrifugal pumps in the working principle. They are machines that increase the energy of solid and liquid mixtures by means of centrifugal force (the rotation of the impeller of the pump). A device that converts electrical energy into kinetic and potential energy of a medium.
- There is a science behind the design of a >slurry pump, based primarily on the processes and tasks it will perform. This is why it is important to use the right slurry pump for your specific needs. In a field that encompasses so many specialities, long-lasting, efficient and reliable quality equipment is essential.
- What we mean by slurry is basically a liquid containing solid particles. When you want to pump this slurry, there are different requirements than when pumping only dirty water. A waste water pump cannot handle the solid particles of a slurry. This is where slurry pumps come in handy. >Slurry pumps are heavy duty and robust versions of centrifugal pumps, capable of handling tough and abrasive tasks.
- The selection of a dredge or , slurry pump, can be a challenging process that can be simplified by understanding the main factors behind the smooth operation of a pump. In addition to providing more efficient performance, the right dredge pump requires less maintenance, lower power and a relatively longer life.
- Rubber lined pumps offer many advantages
- One problem with centrifugal pumps is that the velocity and shear forces within the pump may damage the slurry/solids. Typically, twin-screw pumps cause the least damage to solids in the slurry.
- Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.
- Slurry pumps can be used to transport mixtures of liquids and solids in many industries in a wide range of applications, such as mine drainage, dredging of sunken lagoons and pumping of drilling mud.
- Better safety
- Dredge pumps are designed to transfer large quantities of fluids and solids.
- On the other hand, if the slurry is not only abrasive but also has a low pH, then a duplex stainless steel construction is preferable. This material is best suited for slurry pumps to withstand harsh materials (such as acids) while still having a high Brinell hardness.
- >Slurry Pump
- A slurry pump is a mechanical device used for the pressure-driven transfer of a fluid mixture (aka slurry). The fluid mixture consists largely of water as a liquid and solids as minerals, sand, gravel, human excrement, drilling mud or mostly crushed material.
- All manufacturers are consistently involved in product development in the long and short term. Customers should expect to benefit from these developments in a number of ways: increased efficiency, increased reliability, reduced operating costs, or a combination of both.

- - Portable and low maintenance - There are no long or exposed mechanical shafts between the motor and worm gear, which makes the submersible pump more portable. In addition, because there are no long or exposed mechanical connections between the motor and worm gear, less maintenance is required and operating costs are significantly lower.
- Sites often rely on centrifugal pumps to provide slurry service. These pumps (and their associated piping systems) require special provisions that demand detailed knowledge of the properties of solids and slurries to prevent wear, corrosion, erosion and other adverse effects such as solids settling. Specifying the optimum combination of speed, geometry and material requires a proper balance of often conflicting pump priorities; this requires consideration of stable operation, maximum wear life, operational flexibility and minimum energy consumption.

- 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.
- In addition, a new level of complexity is added to an otherwise simple machine. Other parts must now be inventoried and training beyond basic spanner turning is required. When it comes to pumping rock and some of the world's most abrasive materials.
- The slurry pump is mainly used in the mining industry, its wear resistance is strong. So It conveys slurry that containing slag, but it can conveys mud. The mud pump is usually made of cast iron, the wear resistance of the pump is low. So the mud pumps often used for conveying mud or slurry containing suspended particles.
- If centrifugal, are the impellers of the right design and material?
- 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.
- >Dredge pumps are a special category of pumps used in the dredging process. Dredging is the process of transporting submerged sediments (usually sand, gravel or rock) from one area to another. Dredging takes place in the shallow waters of lakes, rivers or seas for land reclamation, dredging, flood control, new harbours or expansion of existing harbours. The various industries that use dredge pumps are therefore the construction industry, mining, the coal industry and the oil and gas industry.
- Better safety
- The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications. There are many drive modes for option, such as V-belt, flexible coupling, gearbox, hydraulic coupler variable frequency, silicon controlled speed, etc. Among them, the flexible shaft coupling drive and V-belt feature of low cost and easy installation.
- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.
- It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.
- Any type of impeller can be used in slurry applications, but closed slurry pump impellers are more common because they are high efficient and abrasion Resistance,. Open slurry pump impellers are usually used well for high concentration solids as they are less likely to clog. For example, the small fibers in paper stock which, in high densities, may have a tendency to clog the impeller. Pumping slurry can be difficult.
- Find a professional slurry pump supplier
- There are three different >types of slurry pump impellers; open, closed, and semi-open. Each has its own strengths and weaknesses, depending on the application. Some are better for solids handling, others are better for high efficiency.

- Mixers can also help agitators when pumping very dense particles. In applications where the tank is small and/or where pumping is desired to lower the water level in the tank, a slurry pump with an internal cooling system should be considered to avoid overheating of the stator (when the water level gets low). When pumping sediment from a dam or lagoon, consider the use of a raft unit, which is a submersible device. Agitators are recommended, as well as one or more mixers that can be mounted on the raft or pump to resuspend particles for successful pumping of particles.
