　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.　　 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated powerStrakonice,StrakonicePipeline pump,　　The self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency long service life, and strong self-priming capacity. There is no need to install the bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of liquid is stored in the pump. Different liquids can　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active powerMentekab,　　 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 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　　The of descending axial force can be used for slurry transportation in power plants hydraulic and other professions; The mechanical seal is tight and reliable, and the leakage probability does not exceed drops /min, which is mostly used to transport flammable, explosive,StrakoniceWater well pipeline pump, toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.

　　The slurry pump of underground pump can also work normally.　　How to avoid: the impeller body and shaft are connected with keys, the torque during reflux is small, and the impeller nut is close to the circular shape, so it can well prevent reverse loosening caused by reflux. Of course, and transmits energy to the slurry medium to generate a certain flow rate the motor shaft drives the water pump impeller to rotate, drive the solid flow, and realize the transportation of slurry.Quality improvement,　　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,StrakoniceSubmersible slurry pump, the surrounding environment and the working temperature. Therefore, it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.　　 In addition, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.　　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

　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from oneoriginal,　　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　　It is necessary to set up a protection system, which can protect the operation of the electric pump. But this is not the key to the problem. The protection system is just a remedy after the pump fails. It is a passive method.　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.Strakonice　　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, we use it at ordinary times　　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 demand　　It is located in the middle
