perforated zinc sheetFirst, galvanizing can enhance the corrosion resistance of the product. Zinc has high potential and excellent anodic protection. When the surface of the product is galvanized, zinc will have an electrochemical reaction with oxygen and water in the environment, thereby forming a dense zinc oxide protective film, preventing the metal from further contact with external oxygen, water and other substances, slowing the corrosion rate of the metal. Galvanized products after wire drawing processing, because the surface of the product has a more dense zinc oxide protective film, it can better resist external corrosion and improve the corrosion resistance of the product.

Read MoreThe drawing process of the product drawing process has a great influence on the product function. Generally, a large total surface reduction rate of about 90% (see area reduction rate) and a small pass surface reduction rate (about less than 23%) are selected to ensure the endurance of the product. On the high strength spring steel wire, drawing should control the exit temperature of each passage of the steel wire is lower than 150℃, to avoid the steel wire due to strain aging and appear to change the crack, which is the formation of steel wire scrap the primary disadvantage.

- The management system of the rinsing water after wire pickling should be discharged regularly and regularly, and the rinsing water should be kept clean and low acid value as far as possible. It is more appropriate to control the pH value of 3. The concentration of plating aid should not be too high. The hot plating wire must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is added without reference to the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.
There is a connection between the hook mesh and the aperture, in short, the general hole small hook mesh, the wire is also very small; Aperture is large, hook mesh wire is generally larger. The weaving of the hook mesh also has certain rules, using the first pre-bent into a wavy wire, and then woven into the hook mesh. According to the knitting method, the hook mesh can be divided into: closed weaving, two-way plain weaving, one-way corrugated weaving, two-way plane weaving, two-way corrugated weaving, rectangular hole weaving.

- With the development of the dredging market, the requirements for dredging equipment are getting higher and higher, and the suction resistance and vacuum of dredging pumps are getting higher and higher, which has a great impact on the efficiency of dredging pumps and the chance of cavitation is getting higher and higher. The number of >dredging pumps is also increasing.
- Types of slurry pumps
- Rubber is lighter and softer than other wear lining materials. This aids installation because it is easier to lift and install quickly and efficiently. Positive results for the health and safety of workers in the field.
- Types of slurry pump installation.
- In AIER® slurry pumps, WY & WYJ sump pump are vertical centrifugal slurry pump, submerged for transfer abrasive, coarse particles and high density slurry. When working, it needs no seal water or any kind of seal. It can work well as well when suction volume is not enough.
- One of the most frequently asked questions from our team of pump experts is: How do I pump slurry?xa0With this in mind, our team of experts have provided a useful guide to pumping slurry.
- The length of the piping. The longer the pipe, the more slurry-induced friction the pump needs to overcome.
- 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.
- Some models can generate discharge pressures up to 260 ft. (80 m).
- If centrifugal, are the impellers of the right design and material?
- Especially when the dredging depth reaches 20m or more, the above situation will be more obvious. The use of underwater pumps can effectively improve the above situation. The lower the installation position of underwater pumps, the smaller the suction resistance and vacuum, which can obviously reduce the losses during the work and improve the working efficiency. The installation of underwater pump can effectively increase the dredging depth and improve the ability to transport sediment.
- 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.
- 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.
- What are the materials used to construct the pump?
- 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.
- As described below, there are several , types of pumps, that are suitable for pumping slurries. However, before considering which technology to use, we must address several key issues.
- Reduced inventory
- The terms flushing and quench, often seem to be confused or misused when discussing seal support schemes for , slurry pumps, . As the concepts of a mechanical seal cartridge and a filled seal cartridge are slightly different, I will discuss them separately and in turn.
- In dry installation, the hydraulic end and drive unit are located outside the oil sump. When using a submersible slurry pump for dry installation, the slurry pump must always have a cooling system installed. Consider the design of the water tank in order to deliver slurry to the pump. Agitators and side-mounted agitators cannot be used for this type of installation.
- Slurry Pump Impeller
- It is important that the pump you choose has components that will not wear out from abrasive slurries.
- Slurry pumps are mainly used in industrials of mining, metallurgy, dredge, power, coal and other solid slurry transport.
- Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.
- Monitoring
- -When pumping abrasive slurries, it is essential to use wear-resistant components with a high chromium content. But more is not always better - above 25%, the impeller becomes brittle.
- What style of pump is suitable?
- Traditionally, centrifugal pumps are used to pump highly abrasive slurries. Centrifugal pumps use the force generated by the rotating impeller to impinge kinetic energy into the slurry.
- When the slurry pump working, pump parts are easy to be impacted, wear, and corrosion, etc. Therefore, the liner of the slurry pump uses wear-resistant material, such as high chromium alloy, rubber. The wear-resistant materials can effectively reduce the wear parts of the pump. So most of the slurry pump is a wear-resistant slurry pump in the current market.
- If a centrifugal pump, is the design and material used to construct the impeller suitable for pumping slurries?
- In harsh conditions with sand, sludge, rocks and mud, ordinary slurry pumps tend to clog, wear and fail frequently. But WA heavy duty slurry pumps are highly resistant to wear and corrosion, which means that the service life of our slurry pumps is better than other manufacturers' pumps.
- As new coal-fired power plants come on line to meet the growing demand for electricity in the US and around the world, there is an increasing need to clean plant emissions to meet clean air regulations. Special pumps help to operate these scrubbers efficiently and handle the abrasive slurries used in the flue gas desulphurisation (FGD) process.
- Determine the operating parameters of the pump.
- Metal and/or rubber pump bushings are used to combat the erosion of solid particles found in the slurry. Metal slurry pump housings are usually made of carbide to resist erosion caused by increased pressure and circulation. Sometimes wear-resistant steel is used on the pump casing so that the pump can be welded if repairs are needed.
- The main objective of all flush water programmes is to prevent contamination of the seals by pumped water.The flush water programme for boxes is therefore very similar to the flush water programme for mechanically sealed boxes. However there are still some obvious mechanical differences. The most notable difference is the addition of a seal (packing) between the inlet and outlet limits. This minimises the amount of flushing fluid consumed.
- >Slurry Pump VS Mud Pump
- 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.

- Mud pumps are mainly used for drilling, pharmaceutical, brewing, paper, and other industries, which used to transport suspension.
- Underwater installation
- A clear clean fluid supplied from an external source is normally used which is delivered to the main sealing surface on the fluid side of the sealing process. By using a closed gap throat bushing, the stuffing box can be back-pressurised to a higher pressure, ensuring that the flushing fluid does not flash across the seal face.
- - 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.
- Choosing the right slurry pump
- For pumping abrasive slurries, these types of pumps can also be made from specialised high-wear alloys. Hardened stainless steel is also a common choice for abrasive slurries.
- 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.
- Aier Machinery Hebei Co., Ltd. is a large-scale professional >slurry pumps manufacturer, gravel pumps, dredge pumps, sewage pumps and clean water pumps in China.
- Fewer and thicker vanes on the impeller. This makes it easier for solids to pass through than the 5-9 vanes on a standard centrifugal pump - typically 2-5 vanes.
