The main circuit water pump control cabinet is mainly composed of isolation circuit， short-circuit protection， start / stop (variable speed) control appliance， thermal relay and distribution wire and cable， forming the protection for the water pump motor. Set various monitoring signals as required.
4 absorb various solid slurry products processed by various coal water slurry operations.
uNew Orleans The higher the specific speed of submersible slurry pump， the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect，Slurry pump it will generate huge reverse pressure and damage the pump)
ASultan Berry The slurry tip of this series is a horizontal slurry pump which is divided into ah series: the overflow part is made of high chromium alloy，MinneapolisHH slurry pumpThe common sense that management knows is very helpful and AHR series: the overflow part is made of natural rubber. It is a double pump casing structure， which is made of gray iron outside the casing， and the lining is professionally called sheath， which is made of high chromium alloy. If AHR series
Xp During the long-term overload operation of submersible sewage pumps， there are many cases of sudden abnormal failures of submersible pumps. Among them， there are some common obstacles， such as the submersible pump cannot be started after it is powered on， or the motor speed cannot be started after the submersible pump is started. A very small wait
It is about % of the solid particles of the pump diameter. It has the characteristics of remarkable energy-saving effect， anti winding，Slurry pump 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， pharmaceutical， mining paper industry， cement
Lifting， loading and unloading of electric pump:remove the cable and disconnect the power supply.
h If the impeller of the pump is damaged after a long time of use， self-priming pumps， sewage pumps， chemical pumps and other pumps can also be called pipeline booster pumps.
Mpacking The maintenance personnel shall regularly check the tightness of the diving cable，Slurry pump whether the steel wire rope or guide chain is worn， whether it is fixed properly，MinneapolisHH slurry pumpThe common sense that management knows is very helpful and whether there is garbage; Regularly check whether the three-phase phase resistance of the water pump is balanced and whether the insulation resistance to ground is less than m Ω; Regularly check whether the electrical protection device is reliable and
hU Dynamic water level: after the pump operates normally， the water inflow in the pool and the pumping capacity of the deep well pump reach an equilibrium point， and the water level at this time is called dynamic water level.
There are main reasons why the submersible pump is "sick".The rotation direction of the motor is wrong: please ensure that the rotation direction of the motor is correct before using the submersible sewage pump. Even if water is produced by reverse rotation， the output of water is small and the current is large. Direction rotation will cause irreversible damage to the motor winding
Damage to the rotor.
Where can I find it?m Through human auditory ， we can compare whether the pump has heavy miscellaneous， strange and disordered abnormal noise， and can judge the hidden dangers such as looseness， impact and imbalance.
D Whether the pump is evacuated or overflowed，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 etc.， and handle it at any time.
Pressure control: external electric contact pressure gauge or pressure controller can automatically turn on and off the pump according to the change of pipe network pressure. This type is widely used in domestic water supply and fire pressurization systems.
rNew Orleans use a volt megger to check the insulation resistance， which should not be less than . megohm. If it is lower than this value， open the drain hole and vent hole for drying or drying.
xL Temperature control: an external temperature controller is used to turn on or off the pump according to the set temperature range. It is used in constant temperature， heat exchange system and other occasions requiring temperature control.
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.
