It is worth noting that the vertical pipeline pump can work like the self-priming pump after it is equipped with a siphon device. However， due to the existence of the self-priming pump， few people will install this device for the vertical pipeline pump.
5 Check the three-phase current with an ammeter on the control panel. If the phase power supply is found to be insufficient， the power supply of the submersible pump shall be turned off immediately. Check whether the cable connector， connection point and power switch contact are in poor contact and whether they are the main line. Check whether the circuit wiring is broken or loose or whether the fuse is damaged or burnt out
gVirginia Beach The balance ring is also disassembled;Then remove the last stage impeller and the key back， and the middle section including the guide vane; in addition，Mixing submersible sewage pump remove the impellers，MesaBooster pipeline pumpAnalytical principle of frequency conversion energy saving middle sections and guide vanes at other levels in the same way until the submerged slag slurry
Environmental conditions for normal operation of ordinary YLB motor:
BSanto With protection . cf fire control cabinet integrates many electrical components， which can form a three-dimensional protectionfor the fire pump， including voltage overvoltage and undervoltage protection， current overcurrent and undercurrent protection， overload protection phase loss protection， overheating protection， etc. this
Cq The sand suction pump and sand water separator in the aeration grit chamber of the screw pump operation pre-processing unit are used to remove the sand particles in the sewage. It is necessary to ensure their normal operation， so as to reduce the sand particles in the sludge and prolong the service life of the screw pump.
The casing ground wire of the electric pump shall be connected in strict accordance with relevant regulations. When the electric pump is running， it is strictly prohibited to work or move in the water of nearby devices or people，Mixing submersible sewage pump in case of accidents caused by the power distribution of the electric pump.
This can ensure that the water pump has been running at the best operating point， which not only meets the process needs， but also reduces the equipment loss， and is conducive to extending the economic service life of the equipment.
t drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump， so the water ring vacuum pump is used for exhaust to achieve theof water inlet.
W other requirements (cable， control box， liquid level control， etc.)
MAdministration Reduce maintenance costs. After the deployment of the fire pump， it also needs to be maintained regularly. Manual maintenance requires a lot of manpower， material and financial resources，Mixing submersible sewage pump and the maintenance cost is very high. The use of cf fire control cabinet can greatly reduce these maintenance costs
gG Article experimental water shall meet the following requirements: The water treatment equipment shall be set in a separate room， and the material of the water supply pipeline shall be anti-corrosion and rust proof，MesaBooster pipeline pumpAnalytical principle of frequency conversion energy saving Li is a centrifugal pump. The slurry pump can also be divided into other different types from other angles. Let&#;s see from what angle Panshi pump can classify the slurry pump: first， the suction inlet of the slurry pump
(b) The maximum ambient air temperature varies with seasons， but does not exceed ℃.
whereu Work to prevent the electric pump from overheating and damage. The technical guidelines for laboratory construction in medical institutions (Trial Implementation) directly proposed that stainless steel should be used. Compared with the technical code for construction of biosafety laboratories (gb-， copper pipes and non-toxic plastic pipes are no longer proposed.
C There is also a vibration method to measure the vibration frequency of the pump， and the measurement is relatively simple. However， the measurement results may have some errors. When using the submersible slurry pump， there are other vibration sources that will affect the measurement results， the cause shall be found out immediately or the pump shall be shut down for inspection. The cable shall not rub against the shaft wall to prevent the well water from penetrating into the motor along the cable core after the cable is worn.
lVirginia Beach when the design flow is required，Submersible slurry pump, WQ submersible sewage pump, submersible sewage pump, deep well pump, pipeline pump, AH slurry pump, QJ submersible pump, HH slurry pump - Hebei Xinjiasheng Pump Industry Co., Ltd the dynamic water level of the well is m
oU Or the liquid contains fibers. For the medium with solid particles such as paper scraps， the temperature of the medium to be transported is usually not greater than ℃.
Clean up the silt and other obstructions in or around the water pump.
