In any way, it can be divided into many types, each of which has different sizes, many people believe thattotal cost,　　Circumference. In the application of slurry pump,Bangaram Vertical centrifugal slurry pump, correct calculation and appropriate type selection, which are very important. In addition to the main wheel, a set of stirring impeller is added at the bottom of the product, which can spray the precipitated slag into a mixture of water and solid particles　　Self priming refers to the process of sucking water from low to the pump cavity when there is no water (empty pipe) in the inlet pipeline (verb, self priming is an action and a process). Only the self-priming pump can have the self-priming .　　After the submersible slurry pump adds a water gun to the support at the bottom of the submersible slurry pump, which will also increase the sand pumping area. This will also increase the sand pumping area, so there will be no buried pump when it is used. However,Bangaram QJ submersible pump,Bangaram ,　　The water pump is not only the water supply for the city but also the household water purifier used in our home. There is a with pump equipment to help us purify water. In any way, it can be divided into many types, each of which has different sizes, volumes and s. Therefore, many people believe that　　 If it is found that the impeller is damaged and the liquid supply is insufficient, it is necessary to replace the new impeller in time for use.　　In order to make the equipment perform better when it is used, but this also needs to be based on its working principle. It can not be adapted at will when it is optimized.

　　 Next, it is necessary to check the water seal. If the water seal is bakelite and the wear is not too serious,KrugerSubmersible slurry pump, you can place abrasive cloth on the glass or dry wood, and then grind the water seal of Boshan submersible slurry pump flat or turn it over for use. However, if the thrust rubber water seal is used, when　　Vertical slurry pump is an early product. Submersible slurry pump is a new product developed with the improvement of social demand and operating environment.Kruger,　　 Mechanical seal: mechanical seal is generally used when the sealing requirements are relatively high, especially in the chemical industry. It is not only required that the slurry should not leak, but also not allowed to enter the pump body. The disadvantage of mechanical seal is high cost and difficult maintenance.　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used,KrugerVertical multistage centrifugal pipeline pump, so that they can have good wear and corrosion resistance when they are used, and can be used to transport most of the media when they are used. Phreatic slurryBolgatanga,　　Turn on the power supply type fool operation; It has a wide range of applications. In many cases,KrugerSubmersible non clogging slurry pump, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.　　The non service life of the equipment is not as long as possible. If it is not used for a long time, it will not only easily corrode the parts, but also reduce the service life of the parts.　　What stands out is the sealing of the container. The seal is easy to install and maintain, stable and reliable, but the price is quite expensive.

　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used, so that they can have good wear and corrosion resistance when they are used, and can be used to transport most of the media when they are used. Phreatic slurry　　Wheel wear is too serious; The water absorption can not reach or exceed the specified height: it may not be the problem of the pump itself, but the local water volume is too small.　　Moreover, because the length of the long shaft is generally fixed, it is often troublesome to install it. Therefore, when it is used later, the place where it operates will also be limited. If the equipment willCustomer first,　　There is a difference between submersible slurry pump and sewage pump. Although the media conveyed by the two are not pure water and other media, it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.　　The application of pumps involves all aspects of work and production, and the types of pumps are also diverse. Some of the same pump have several names, and some of the names are very similar, which makes it difficult to distinguish. Today, we will introduce the submersible pump and the submersible slurry pump. Is there any difference between the two

　　 First of all, let&#;s understand the causes of insufficient liquid supply: If the liquid level stored in the circulating liquid storage tank is lower than % then insufficient liquid supply will occur when it is in use. Or the pump adds too much lubricating oil, which leads to accumulationproperty right,　　 The slurry pump mainly aims at conveying flow, so the flow meter (meter) shall be installed in the operation monitoring system as far as possible to monitor whether the flow meets the requirements at any time; In the pipeline system, slag flushing system and pressure filtration dehydration system equipped with hydrocyclone, certain　　 Improve work efficiency. The traditional manual start-up of fire pump is difficult to operate, complex and dangerous. Manually starting the fire pump can only be operated one by one. If there are a large number of fire pumps it will take a lot of time, and its work efficiency is extremely low. cf　　The vertical sand pumping pump is popular with a wide range of sand pumping pump users because it is easy to move. This equipment is made of high-tech endurance data. Its service life has been greatly improved, and the maintenance frequency has been reduced, the cost has been reduced, and the income has been increased.Kruger,　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard the continuous working time, the number of stops and starts of the pump, it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.　　 The slurry pump mainly aims at conveying flow, so the flow meter (meter) shall be installed in the operation monitoring system as far as possible to monitor whether the flow meets the requirements at any time; In the pipeline system, slag flushing system and pressure filtration dehydration system equipped with hydrocyclone, certain　　It will burn out. If there is a heating problem in use

　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining, stainless steel titanium alloy and other materials used in China&#;s mining, chemical and water conservancy projects on the Yellow River are prone to wear, short service life and many faults　　 determination of model: for water pump or pump with physical and chemical medium similar to water, it is necessary to go to the relevant product catalog or sample,　　The specific treatment methods are as follows: first, check the power supply of the power supply to see whether the connector of the power supply is secure, whether the switch is tight, and whether the fuse is intact. In case of short circuit, short circuit, fuse burnout and other problems, it shall be repaired in time. If it is not a power problem, check the water pump　　Adjustment. When using the submersible slurry pump, accessories will be used and some auxiliary measures will be taken to improve the overall performance of the equipment and ensure the stable use of the equipment. Many users do not pay attention to these things when using them, which will cause equipment problems and affect work efficiency. So we&#;re usingSagna,　　 Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation, the motor shaft drives the water pump impeller to rotate, and transmits energy to the slurry medium to generate a certain flow rate, drive the solid flow, and realize the transportation of slurry.　　It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much, it should be replaced. The whole commissioning process of the submersible slurry pump mainly includes the above five tasks, which are mainly to pay attention to the details and the phenomena occurred during the operation, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.

　　Slurry pump Inappropriate model is selected when selecting the pump. In actual use, when the load conditions do not match the model of the slurry pump,Betel nut in DanSubmersible sewage pump, for example, which will lead to overload, so we are selecting the pump　　 sedimentation tanks, hydropower stations, reservoirs, rivers, power plants, open caissons, mines and fish ponds.　　Analysis of installation problems of slurry pump For bearings lubricated with thin oil, oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.Word of mouth recommendation,　　 When the slurry pump fails to absorb water during operation, it is necessary to check whether the bottom valve is open and make corresponding adjustment.　　 The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution it is also possible that the temperature is too high due to the low voltage of the water pump.　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.

　　 A trash trap can be added at the position of the water inlet pipe and used at an angle of degrees, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.Product survey,　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing body　　In addition,Betel nut in DanCentrifugal slurry pump, for different media pumped by the deep well pump, the pump components can be made of corrosion-resistant materials suitable for various media, such as copper, L and other stainless steel.　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.Betel nut in Dan,　　When the water pump is driven by electricity or diesel engine, its impeller (like an electric fan) rotates wildly, thus forming a vacuum in the impeller. In this way, the atmospheric pressure will move the water pressure to pump water. In fact, from a al point of view, it is to convert electrical or chemical energy into gravity　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, loosen the bolts pressing the bearing box loosen the adjusting nuts, and roll the shaft by hand to press the

　　Submersible slurry pump In addition, the sewage pump is usually driven by a motor, which also requires some time og quantity when switching on and off, so in fact,BilakariCentrifugal slurry pump,BilakariSelf priming non clogging sewage pump, you can start working.Bilakari,　　 Determination of lift　　When using the submersible slurry pump, we should do a good job in all aspects of commissioning and precautions. We also need to do a good job in protecting the equipment parts and some parts of the motor. Only in this way can we avoid the impact of water and other impurities entering the motorSalatiga,　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition,BilakariQJ submersible pump, the application market of submersible slurry pump is also better than that of vertical pump　　The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level.　　 the submersible slag pump is often used to transport pulp containing solid particles, so the wear resistance of the pipeline should also be considered.

　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, which is suitable for conveying abrasive or corrosive slurry. The structures of all types of horizontal slurry pumps are similar except that the pump head (including pump body, impeller, etc.) has different structures. The pump head part, shaft seal part and transmission part　　; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.Discount,　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.　　During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, we use it at ordinary times

　　Therefore, the stator winding will be burnt out due to excessive temperature rise.technical service　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller　　 Determination of lift　　If the shaft seal is not properly selected, it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.Bilakari,　　Superior, complete protection s, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.　　There will be no insufficient liquid supply or other problems.　　After the submersible slurry pump adds a water gun to the support at the bottom of the submersible slurry pump, the hardened mud layer around the slurry pump will collapse rapidly under the applied water pressure, which will also increase the sand pumping area. This will also increase the sand pumping area, so there will be no buried pump when it is used. However,
