When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump, especially in cold winter. Then put it in a dry place. Conditional users can also apply oil to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. in addition　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, protection should be done well, which should be a comprehensive optimization design method.Tampere,　　Then start the spray pump. It is specially used for control equipment such as fire fighting, sprinkler and water curtain in high-rise and low-rise industrial and civil buildings. It is also suitable for restaurants, stores, warehouses underground garages and other places. The ordinary sprinkler head can be directly installed or hung on the sprinkler pipe network　　If the pump outputs more medium liquid, 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 (aboutJabalya,　　It is an auxiliary means of on-site monitoring. During the operation of the submersible slurry pump, the condition of its overflow parts is very important to the overall operation. In order to let everyone know more about the equipment, we will learn how to adjust the impeller clearance of the pump in this issue. I hope it will help you.　　A large amount of lubricating oil is stored.　　Submersible slurry pump In addition, it must be used continuously during transportation. If there is an interval in the middle, it must be avoided that the interval is relatively long, so as to avoid the solidification of slurry in the pump when the operation is stopped.

　　 In addition, but this measurement will also be affected by the surrounding noise,TamperePipeline pump body, so in fact, this measurement is not very accurate.　　Characteristic ysis Starting mode the starting mode of the water pump control cabinet is divided into: full pressure start, star delta step-down start, soft start and variable frequency start. Proper starting mode shall be selected according to power supply conditions and other factors.　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.offer　　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,TampereBooster pipeline pump, 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 one　　For example in the market, for example, the sweeping pump some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics

　　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.Quality assurance,　　Submersible slurry pump In addition, which also requires some time og quantity when switching on and off, so in fact, it can be adjusted to a certain extent during use. The submersible slurry pump needs to use a line when in use　　 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.　　 In addition, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.Tampere,　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller), magnetic dial indicator, outside micrometer,TampereHorizontal non clogging sewage pump, caliper, feeler gauge, square ruler, copper bar, screwdriver with handle, hammer, V-shaped irons of the same specification, clean kerosene, oil basin, cotton yarn, etc.　　Turn on the power supply type fool operation; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.
