　　Demonstration of oil drainage steps for centrifugal wear-resistant and energy-saving slurry pump　What is a centrifugal wear-resistant and energy-saving slurry pump?The concept of centrifugation is based on the principle of pump.There are many types of pumps, and they can be divided into dozens of categories according to different angles.Centrifugal pumps are divided into the working principle of the pump, and are the process of pressurizing the conveying medium through centrifugal force.There are also common types including screw principle, plunger principle, etc., which can be divided into pumps that are different from the centrifugal principle.After talking about the concept of centrifugal pumps, and then talking about slurry pumps, slurry pumps divide pumps from another perspective, that is, divide them from the conveying medium.As the name suggests, the slurry pump delivers a mixture of solid particles containing residue and water.In principle, centrifugal wear-resistant and energy-saving slurry pump is a type of centrifugal pump.The main working parts of the centrifugal wear-resistant and energy-saving slurry pump are the impeller and the casing. The impeller device in the casing is located on the shaft and is connected to 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 on the fluid in its direction of movement, thereby forcing the pressure potential and kinetic energy of the fluid to increase.At the same time, under the action of inertial force, the fluid flows from the center to the edge of the impeller, and flows out of the impeller at a very high speed, enters the pressure outlet chamber, and is discharged through the diffusion pipe. This process is called the water pressurization process.At the same time, since the fluid in the center of the impeller flows to the edge, a low pressure zone is formed in the center of the impeller. When it has sufficient vacuum, under the action of the pressure at the suction end (usually atmospheric pressure), the fluid enters the impeller through the suction chamber. This process is called the water absorption process.Due to the continuous rotation of the impeller, the fluid is continuously discharged and sucked in, forming a continuous work.The working process of the centrifugal wear-resistant and energy-saving slurry pump is actually a process of energy transfer and conversion.It transfers the mechanical energy of the motor at high speed through the pump blades and converts it into the pressure and kinetic energy of the pumped fluid.I believe everyone knows about the centrifugal wear-resistant and energy-saving slurry pump. Oil may be needed when using it. Here is a step for draining the oil of the slurry pump: 1. If you want to drain all the oil in the box, you can unscrew the oil drain plug at the bottom of the box to drain the oil.2. In a short time when the liquid level is lowered, the oil splashing of the bearing against the oil and the plunger spring can be lubricated. The oil tank and the oil filter under the pump are made of 230 mesh/inch copper wire mesh. The oil filter mesh should be cleaned frequently to prevent clogging. When used, the oil temperature of the oil tank should not exceed 60℃. If necessary, appropriate measures should be taken to cool the centrifugal wear-resistant and energy-saving slurry pump.3. When the centrifugal wear-resistant and energy-saving slurry pump is discharged from the outside oil, the liquid level of the oil tank top plate should not exceed 30 mm to ensure the lubrication and cooling of the bearings in the pump. When the jack working chamber volume is too large, another oil tank must be installed to ensure that the liquid level after the oil is discharged from the outside oil should not be less than 100 mm to avoid emptying.4. After the speed-regulating slurry pump is first run for 500 hours, the oil should be changed and the oil tank and oil filter should be cleaned. The oil quality should be tested by visual inspection and testing. When the oil quality deteriorates, the oil should be changed in time. When changing the oil, the oil tank and oil filter must be cleaned at the same time. If there is metal chips or water in the oil, the cause should be found and the fault should be discharged.When the centrifugal wear-resistant and energy-saving slurry pump is working, the pump needs to be placed on land, the suction pipe is placed in water, and the pump needs to be started.Due to structural limitations, the motor needs to be placed on the water surface during operation and the pump is placed in the water, so it must be fixed. Otherwise, the motor will fall into the water and will cause the motor to be scrapped.Moreover, since the length of the long shaft is generally fixed, the pump is more troublesome to install and use, and the application situations are subject to many restrictions.If there is a backup slurry pump, the two pumps will be used in turn.If you can plug the pump, you can only repair the pump. You can add a net to the water inlet to prevent too much impurities from entering the centrifugal wear-resistant and energy-saving slurry pump. This will make the chance of plugging the pump much smaller!

What are the raw materials for vertical liquid slurry pumps? How to choose wear-resistant or corrosion-resistant?According to common sayings in the industry, the raw materials of vertical liquid slurry pumps are metal raw materials and rubber raw materials. Metal and rubber raw materials can be divided into many types. Different vertical liquid slurry pump raw materials should be selected according to different working conditions. The common metal raw materials are A05 and the rubber raw materials are R55.Metals: A05, A07, A33, A49, Cr30, 304 stainless steel, 316 stainless steel, duplex stainless steel Rubber: R55, ethylene propylene rubber, Hypalen, Resin: polyurethane, polyetherester The above categories are various raw materials commonly used in vertical liquid slurry pumps, among which A05, A49, and R55 are widely used.The characteristics of the vertical liquid slurry pump determine the selection of raw materials for the vertical liquid slurry pump. The vertical liquid slurry pump is a centrifugal pump that transports slurry containing solid particles. It should be a simple liquid that is not a simple liquid, so it is generally required to have good wear resistance.Therefore, the raw material properties of the above slurry pump should be wear-resistant.However, in many special working conditions, we have to abandon certain wear resistance and sacrifice wear resistance characteristics.Selection of corrosion-resistant media for slurry pumps　　In many cases, the slurry we transport not only contains solid particles but also has corrosive characteristics　　The selection of raw materials for vertical liquid slurry pumps must be based on the characteristics of the transport slurry. The expensive ones do not necessarily have to be good, but the suitable ones are good　　For example, when we use stainless steel raw materials to transport slurry with strong abrasive slurry, which is very wasteful and has poor effect;　　It is also undesirable for us to use A05 raw materials to transport slurry with strong corrosive slurry.For example, nitrates, sulfuric acids, and strong alkaline slurries have very fierce corrosion properties, generally between PH0-3 and PH12-14. Because raw materials with good wear resistance do not necessarily have good corrosion resistance, it is necessary to abandon raw materials such as A05 and R55 at this time, and then select A49, Cr30, 304 stainless steel, 316 stainless steel, duplex stainless steel, EPDM rubber, and Hypalen. The prices of these raw materials are generally 1-3 times higher than ordinary raw materials, or even more.How to choose raw materials for slurry pumps 1. Slurry with less acid and alkalinity and no sharp angle particles: A05, A07, common metal mines and coal washing, the first use of vertical liquid slurry pump types: ZJ type vertical liquid slurry pump, AH type vertical liquid slurry pump, ZGB type vertical liquid slurry pump; 2. Slurry with less acid and alkalinity and no sharp angles: R55 rubber raw material, common metal mines and coal washing, the first use of vertical liquid slurry pump types: AH typeVertical under-liquid slurry pump; 3. Slurry with large acid and alkalinity and strong particles with strong corrosion: A49, Cr30, a common desulfurization occupation in power plants; 4. Slurry with strong acid and alkalinity and low temperature and certain abrasiveness: select ethylene propylene rubber and Hapalen rubber raw materials, commonly transported nitrates; 5. Slurry with strong acid and alkalinity and low temperature but not high temperature: select stainless steel raw materials; Select vertical under-liquid slurry pump raw materials based on the principle of cost-effectiveness and suitable!

Wear-resistant slurry pump is a special industrial pump that is widely used in the production process in different industries.In the fields of mining, chemical industry, metallurgy, etc., this pump is used to transport high concentration and high viscosity liquid and solid mixtures, such as slag, lime mortar, sewage, etc.Because these substances are highly abrasive and corrosive, a specially designed pump is needed to ensure its stable operation and long life.　　The wear-resistant slurry pump is mainly composed of pump body, impeller, mechanical seal and motor.Among them, the pump body and impeller are the most susceptible to wear, so it is often made of high-hard alloy materials.At the same time, in order to further improve its anti-wear properties, special materials such as ceramics and polyurethane can also be used for surface coating or coating.In addition to material selection, the structure of the impeller is also an important factor affecting its performance.Currently, common impeller types on the market include open and closed. When using it, you need to choose according to the specific situation. Compared with traditional centrifugal pumps, wear-resistant slurry pumps are more suitable for transporting high-concentration and high-viscosity substances.This is because its impeller and pump body have a larger flow channel gap and channel area, which can effectively reduce the phenomenon of blockage and jamming of solid particles.In addition, it also has some design features, such as the mechanical seal adopts a double-end structure, which can effectively prevent media leakage; the pump body and the inlet and outlet pipes are connected by flanges, which are convenient for repair and replacement.　　During use, the pump needs to be regularly inspected and maintained regularly.It mainly includes cleaning the pump body and impeller surface, checking the wear of the mechanical seal, and timely replacing damaged parts.At the same time, it is also necessary to pay attention to controlling the running speed and discharge volume of the pump to avoid vibration and noise caused by overload or idleness.　　Wear-resistant slurry pump is a widely used industrial pump and plays an important role in the production process in different fields.Its excellent wear resistance and design features make it an ideal choice for delivering high concentration, high viscosity liquid and solid mixtures.During use, regular inspection and maintenance are required to ensure its long-term stable operation.

Wear-resistant and corrosion-resistant slurry pumps play an important role in many industrial fields, especially in industries that need to deal with large amounts of slurry, such as mining, chemical industry, water conservancy, etc.Using this pump can improve production efficiency, reduce operating costs, and ensure the safety and stability of the production process.　　The design and manufacturing process of the pump fully considers wear and corrosion resistance.The overflow components of such pumps are usually made of high hard wear-resistant materials that resist wear of slurry.At the same time, the internal structure of the pump body has also been specially designed to reduce the flow resistance of slurry in the pump body and reduce energy consumption.Its excellent performance enables it to operate efficiently under various complex operating conditions.Whether in a slurry environment with high sand content, high concentration, high corrosion, or under harsh production conditions that require long-term continuous operation, it can work stably to ensure the continuity and stability of the production process.In addition, the use of wear-resistant and rot-resistant slurry pumps can also improve production efficiency.Due to its excellent wear and corrosion resistance, this pump can extend its service life and reduce the frequency of repairs and replacement.This not only reduces the cost of equipment maintenance, but also avoids production interruptions caused by equipment failure.At the same time, its high efficiency conveying capacity makes the processing and disposal process of slurry more efficient, thereby improving the efficiency of the entire production line.　　Some issues need to be paid attention to during use.For example, wear-resistant parts should be inspected and replaced regularly to prevent excessive wear from affecting performance; at the same time, attention should be paid to the sealing of the pump body to prevent slurry leakage from causing environmental pollution and production safety issues.　　In general, the use of this pump is one of the key factors in improving production efficiency.The excellent performance of this pump in treating slurry can not only ensure the continuity and stability of production, but also reduce operating costs and improve production efficiency.Its importance is even more prominent in industries that require the treatment of large amounts of slurry.Therefore, in these industries, selecting and using suitable wear-resistant and slurry pumps is one of the key steps to improve production efficiency.
