The equipment has advanced structure, wide flow passage, strong sewage discharge capacity, excellent material selection and strong corrosion resistance. It is suitable for conveying liquids containing solid particles, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.　　Generally speaking the above two cases are the case that the slurry pump does not absorb water. The solutions are also introduced. I believe that people can deal with this problem in time. However, if the problem is serious, you must not adjust it at will. At this time, you should find a professional

　　The two have certain commonalities. They are both submersible. As the name suggests, the pump is in an invasive state when running. The submersible slurry pump is a kind of submersible pump, but generally speaking, people often say that the submersible pump refers to the clean water pump, such as the submersible pump for domestic water and farmland irrigation and pumpingScheme customization,　　 The bus voltage where the motor is located is V.

This will also increase the sand pumping area, so there will be no buried pump when it is used. However,Okazaki,　　After meters,OkazakiScrew deep well pump, the sealing of the equipment can not bear the water pressure at this depth.　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, villa water supply factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.

Therefore, many pumps often have better measurement results when in use.　　Fire fighting awareness is deeply rooted in the hearts of the people. With the improvement of fire fighting awareness, many people pay more and more attention to fire pumps. Some places also began to pay attention to the selection of fire pumps. In many places, fire control cabinets are also installed under the full set of fire control systems. In earlier years, fire control　　 the water pipe shall be short, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.discount, so generally, the open impeller will be used, so there is no need to worry about getting stuck in the process of transporting sewage.　　 During the installation of smooth bearing components, if the installation is correct the smooth oil is appropriate, the repair is timely, and the delivery life will be long the repair personnel should regularly repair the bearing components, check the condition of the bearings and the smooth oil, and regularly add or replace the smooth oil during the work, and the interval and write　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation, and regular maintenance shall be done.

Without pumps, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impeller　　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

　　 A vent pipe is installed at the bottom of the pump, so that when the pump is buried underground, water will be injected into the bottom of the slurry pump through the vent pipe, so that a sand water mixture will be formed at the bottom of the slurry pump,AsakawaBaigang deep well pump, so that the slurry pump can be started normally. The advantage of this approach is that even if　　If it can be started and operated with lubricating water, self-lubricating bearings can be used at the support, or other types of bearings (such as polymer bearings) can be used according to the design or contract requirements.　　Potential energy, pumping water up high.

Backflow will occur when stopped. If it is opened immediately, the motor load will start, resulting in excessive starting current and winding combustion.　　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 gravityAsakawa,　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time.

Driven by this, it and the generator naturally become popularRemchi,　　The installation of submersible slurry pump is a step that needs to be concerned. Since we all care about it, it is mainly because the installation will directly affect the use effect. The installation work should be seamless. Some key operating points can be seen when installing the slurry pump.　　 The submersible slurry pump needs to be inspected after reassembly. If the pulley needs to be rotated by hand, the sound of collision between the impeller and the pump shell needs to be avoided.　　The vertical sand pump is generally a submersible slurry pump. Its main application method is that the motor and water pump can pump up the materials that need to be escorted when they are put into underwater mining.

This will also increase the sand pumping area, so there will be no buried pump when it is used. However,　　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.

　　It is also necessary to clean the ventilation duct to avoid blockage.Quality improvement,　　When in use, it can drive the impeller to rotate so as to drive it to flow.　　 Lifting, loading and unloading of electric pump: remove the cable and disconnect the power supply.　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.Tianjin　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.　　Superior, complete protection s reasonable structure, the water pump will automatically start to supplement the pipe network pressure.　　Screw it down and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.

However, there may be some errors in the measurement results. When many equipment are used there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainly　　In recent years,Rock CityVertical slurry pump, the demand for submersible slurry pumps has increased greatly. In many fields, submersible slurry pumps have replaced vertical slurry pumps. What are the differences between the two? Let&#;s yze.

　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about　　The waste water and dirt of conveying belt particles in factories, steel mills, power plants, coal processing industries, drainage systems of urban sewage treatment plants, municipal engineering,Rock CitySelf priming slurry pump wholesale, construction sites and other industries can also be used to pump clean water and corrosive media.　　Adjustment. When using the submersible slurry pump,Rock CityVertical heavy-duty 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 usingproduction,　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.　　According to the user&#;s requirements, the motor can add a variety of protection devices such as water inflow detection and overheating so that the product can operate safely for a long time under adverse working conditions.　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because

　　Through the introduction, but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way canQuality improvement,　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However, when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainly　　 After one year of use, check the corrosion of the pump, remove the rust and paint. If the submersible pump is not used for a long time, it should be carefully checked and put dry.　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.Rock City,　　If the water leakage is serious, the pump itself generally needs to be placed on land for use you can start working.　　What should be paid attention to in the process? Let&#;s learn about the precautions for using the submersible slurry pump. When the equipment is in use, but its suction pipe needs to be placed in water

　　It is not correct that it has no effect on us.　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation,ShinagawakuSelf priming slurry pump wholesale, which will cause certain economic losses to us.Shinagawaku,　　 No maintenance: if it is not used continuously after startup, the submersible pump will rust and cannot be started. If it is not used for a long time, do not immerse it in water for a long time. Put it into clean water and run it for a few minutes to clean the mud inside and outside the pump.　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pumpSangju　　The above introduction is about the cause ysis of the overload of the slurry pump. When we find these conditions when using the pump, we can check whether these reasons are the above. This is also a reminder that we need to maintain the pump during normal use. latent　　 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 accumulation　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.

　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.　　Distance from the dynamic water level of the pool to the center of the water outlet of the pump base (m)　　Promote the continuous expansion of the sales network group.system,　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flows　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift the cut impeller is usually used. The cut is　　Submersible slurry pumps are mainly used in mining, metallurgy, coal, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example, in the field of chemical industry, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation, etc. Submersible slurry pump blade
