In some dangerous situations, a single fire pump can not meet the needs, and multiple fire pumps are required to work at the same time,　　The above four methods can be used to detect whether the submersible slurry pump has cavitation, because if the equipment is in use, it will have a great impact on the operating efficiency. Even if the cavitation time is long, it will also have a certain impact on other parts of the equipment. Sometimes submersible slurry pumpoffer,　　Let the medium containing some solid particles generate a certain flow rate, so that the equipment can drive the solid to flow when it is in use, it is actually quite simple　　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.　　Potential energy, pumping water up high. However, the equipment is shaped like a decoration,ZetikaraVertical slurry pump, so what is the reason for this situation? How to solve it?

　　 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.safety requirements ,　　 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.　　 pump room height and allowable lifting height of lifting equipment　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced which maximizes the reliable operation of the mechanical seal and greatly extends its service lifeZetikara,　　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. The equipment will not be used after burning out,ZetikaraUsed pipeline pump, which will cause certain economic losses to us.　　The slurry pump of underground pump can also work normally.　　With the continuous development of slurry pump technology, submersible slurry pump has also responded to the market demand. At the same time, this type of pump is especially suitable for the depth where the vertical slurry pump cannot operate. Pay attention when using the equipment. The submersible slurry pump can operate if its depth is less than m, but it exceeds

　　 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　　Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial, so the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demandGuiyang,　　 connection dimension requirements of pump base outlet (requirements for companion flange and diameter, outlet center height, etc.)　　 If the power cord is not well contacted, it will also lead to the burning of the motor.Surin,　　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.　　At the same time, it can transport the slurry, and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal use

　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland, after hours of use, check whether the seal is good. In the future, check it once a month. At the same time, check whether the shielding sleeve between the motor rotor and stator is well sealed. Try to reduce the number of starts in use.　　 When adding lubricating oil to the pump at ordinary times, the metering must be controlled,　　When this type of pump is used at ordinary times,GuiyangVertical multistage centrifugal pipeline pump, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so that　　Rate loss so shaft power = effective power + lost power.　　The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in use

　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation without noise and vibration, and the site is cleaner.Price,　　 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.　　 Check the voltage to see if the voltage is too low to drive. Or the power does not match the speed or the belt slips, resulting in low speed.　　It is occasionally found that there is insufficient liquid supply when using, so what are the reasons for this situation and how to deal with it.Guiyang,　　The direction of the differential pressure force is opposite,GuiyangSingle stage slurry pump, which can offset part of the axial force and prolong the service life of the bearing.　　It can improve the mechanical efficiency to a certain extent. Moreover, the molecular structure of the coating itself has good compactness,GuiyangCirculating hot water pipeline pump, which can well isolate the air, water and other media from the pump impeller during use, and also reduce the corrosion and rust as much as possible　　In order to ensure the demand for water and electricity for production and living many units, hotels and residential areas in various provinces and cities in China have purchased it and generators. Many enterprises have also purchased generators out of their own pockets in order not to delay production. Driven by this, it and the generator naturally become popular

　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family when we use it, the flow is small　　 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,　　If you want to know how the slurry pump is classified,FuzhouSelf priming non clogging sewage pump, you must first understand what the slurry pump is: conceptually, it is a machine that increases the medium energy of the solid-liquid mixture through the centrifugal force generated by the rotation of the impeller, and a device that converts the electric energy into the kinetic energy and potential energy of the medium. and　　Troubleshooting: first increase the water pressure, then inject water into the pump body,FuzhouBaigang deep well pump, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.Latakia,　　If there is a standby pump, it is better to use two pumps in turn. If the pump is stuck, the pump can only be repaired. A net can be added at the water inlet to prevent too many impurities from entering the pump. In this way, the probability of pump sticking will be much smaller!　　Screw it down, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.　　At present, the temperature of the motor is very high, some even as high as ℃. In this case, it is easy to burn the motor and replace it with a new one. In fact, one motor burns out at this time. Don&#;t worry about replacing it. You must find out the cause of the motor&#;s heating, or　　 Check the surrounding environment: when the ambient temperature is higher than ℃, the temperature of the air inlet will rise resulting in overheating of the motor. Try to improve the working environment. Such as setting up shade sheds for shading.　　Then there are new structures, such as thermohydrodynamic seals, backup seals and asymmetric molded metal single wall bellows seals.Design brand,　　The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in use　　Rate loss, so shaft power = effective power + lost power.　　 The submersible slurry pump needs to be inspected after reassembly. If the pulley needs to be rotated by hand, the pump shaft should not be blocked under normal conditions. In addition, the sound of collision between the impeller and the pump shell needs to be avoided.

　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.Installation conditions,　　 one method is to use ultrasonic method to detect whether the equipment has cavitation. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, the leakage preventer will cut off the power supply of the submersible pump to ensure the normal operation of the equipment.　　In the mud pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, and the resultant force is the sum of the two forces. If the submersible slurry pump is equipped with an auxiliary impeller, the liquid effect is on the auxiliary impellerFuzhou,　　 There is also a vibration method to measure the vibration frequency of the pump, and the measurement is relatively simple. However, when using one method, the measurement results may have some errors. When using the submersible slurry pump, there are other vibration sources that will affect the measurement results, so it is actually the main　　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.　　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,
