Functions of cf fire control cabinet:Strengthen management. Normally， the use and daily management of fire pumps require manual operation
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， oneortwo managers are often unable to manage them，
4 Shaft seal partauxiliary impeller shaft seal: through the impeller action of a reverse centrifugal force，Hot water pipeline pump the single-stage pump or the first stage pump in series can adopt the auxiliary impeller shaft seal，OmahaDeep well pumpIt has laid a foundation for the development of heavy industry enterprises and the auxiliary blade shaft seal is not required
uMinneapolis It may also be because the pumps liquid supply pipe is blocked by other substances during normal use.
The pump fails to supply water or the flow is insufficient. The pump fails to supply water or the flow is insufficient. It is likely that the suction pipe has water leakage or the bottom valve has air leakage， but there are several possible reasons: the water inlet is blocked; The bottom valve is not deep enough underwater; The running speed of the water pump is not enough; leaf
EAltagrasia Transmission part all kinds of horizontal slurry pumps adopt the same series of transmission parts， including bracket and bearing components. The pump shaft has large diameter， good rigidity， short cantilever， and will not be bent and vibrated under bad working conditions. Heavy single row or double row conical roller is selected for the bearing according to the transmitted power
Or In fact， stainless steel is not only advocated in the medical industry， but also widely used in the water pump industry. The stainless steel submersible pump of denang pump is one of them.
If the flow exceeds QD， cavitation and vibration will occur，Hot water pipeline pump which will seriously affect the service life of the pump. Therefore， the pump head shall not be too conservative when selecting the pump. It shall be as close to the actual head of the pipeline as possible. Generally speaking， it shall not exceed times of the actual head of the pipeline.
z During normal operation， 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. Dont worry about replacing it. You must find out the cause of the motors heating， or
G Open when the power supply is abnormal: the difference between the power supply voltage and the rated voltage shall not exceed %. If the voltage is too high or too low， the temperature of the submersible sewage pump will rise. If the power supply is turned on abnormally， the service life will be shortened or the submersible sewage pump will burn.
REquipment maintenance And it shall be used according to the quota specified in the manual.
mW Using the fire control cabinet can improve the working efficiency of the fire pump. The fire control cabinet can meet the s that cannot be provided by a single fire pump，Hot water pipeline pump such as theof simultaneous startup. In some dangerous situations， a single fire pump can not meet the needs，OmahaDeep well pumpIt has laid a foundation for the development of heavy industry enterprises
Easy installation and maintenance. Small submersible sewage pumps can be installed freely. Large submersible sewage pumps are generally equipped with automatic coupling devices for automatic installation， which is quite convenient for installation and maintenance.
Solution: Please perform parameter initialization (item F and re edit the parameter (possible cause: there is a conflict between item F and item f
investmentl The treatment method is as follows: first， check the circuit voltage to reduce the speed of the water pump.
L Stability and reliability of seals between pump bodies.
Motor heating: cause: A. whether it is overloaded; b. Pump motor failure; c. Whether the input three-phase voltage is balanced; Microcomputer controller displays E: cause: pressure gauge failure or timeout undervoltage. In this state， press the key to eliminate the alarm.
cMinneapolis Operation management of sewage pump operation management of submersible pumpadjust the liquid level to make the water pump operate at the best operating point. After the equipment is selected， anti winding， non blocking， automatic installation and automatic control. It has a unique effect in discharging solid particles and long fiber waste. Very suitable for chemical， petroleum，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 pharmaceutical， mining paper industry， cement
Determine the head h. After the flow is determined， determine the inlet and outlet pipe diameters of the pump， complete the layout of the whole pipeline， and determine the head. In the actual selection， the resistance coefficient of the pipeline is often too large. In addition， when selecting the pump model a head margin is added， resulting in
