optimal water inflow of well m/h
3 If the three-phase current of the submersible sewage pump is large and stable the submersible pump cannot be started. The reason can only be understood from the submersible pump. Submersible pump bearings may be damaged and the pump may be blocked. The impeller is full of groceries. Submersible pumps shall not be used for sundries， such as those wrapped around the pump shaft
wColorado Springs Start the priming pump. Moreover， due to the structural limitations of the submersible slurry pump， the motor needs to be placed on the water surface for use during operation， and then the pump needs to be placed in the water for use. Therefore， the submersible slurry pump must be
Check the water pump: it is possible that the selection of the water pump is not matched with the motor，Multistage pump which makes the temperature of the motor too high after long-term operation; It is also possible that the working time exceeds the specified working time of the motor. At this time，Long BeachBaigang deep well pumpDescription of main production process the use time and times should be strictly limited， the correct thermal protection should be selected， and
HHeranietzsche The fire control cabinet adopts centralized management and one key operation. The startup procedure is simple and convenient. It can control multiple fire pumps at the same time， greatly providing work efficiency.
Nt Functions of cf fire control cabinet:Strengthen management. Normally， maintenance and management. However once large shopping malls are encountered and there are a large number of similar fire pumps，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 oneortwo managers are often unable to manage them，
The failure to start the water pump may be caused by the power supply or the failure of the water pump itself.
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.
o The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.
P Damage to the rotor.
Tsystem There is a blockage in the water pump.
pE On the rack.
the pipeline shall be designed as a circulating circuit to minimize turning， prevent microbial breeding and reduce water quality.
Stainless steel deep well pump is not a disposable product， nor a short-term product， but a long-term equipment. One investment can ensure long-term profits，Multistage pump and there is no need to replace equipment in a short time. Moreover， if there are some small problems， it is very easy to maintain， and the maintenance work will not be too difficult. therefore
Analysis projectg The quality of the substitutes produced is not up to the standard，Long BeachBaigang deep well pumpDescription of main production process and the price of imported spare parts is expensive; Moreover， in the subsequent sludge treatment unit， the flow passage parts of the centrifugal dehydrator are more sensitive to sand particles. Therefore， sand particles in the conveying medium shall be minimized.
Y In order to ensure the demand for water and electricity for production and living，Multistage pump many units， it and the generator naturally become popular
Take out the locking ring of the coupling， unscrew the fixing screw and remove the connecting bolt to separate the motor and water pump.
dColorado Springs Solution: replace the remote pressure gauge; Replace the pressure transmitter; Check the connecting signal wire.
kE Whether there is any fault.
check the cable and replace it if it is broken or broken to avoid leakage.
