Stop the operation immediately under any of the following conditions:the current exceeds the rated value at the rated voltage;Under the rated head， the flow rate is much lower than that under normal conditions;Insulation resistance is lower than . megohm;When the dynamic water level drops to the pump suction;When the electrical equipment and circuit are out of specification
6 Service conditions
aAurora It needs to be replaced in case of damage， swelling and deformation， insufficient spring pressure， breakage， etc.
Operation management of screw pump Nemo pump (single screw pump) is a positive displacement pump，Slurry pump short-circuit protection，BakersfieldQJ submersible pumpsupply overload (backup) protection circuit， 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.
Pf The main circuit water pump control cabinet is mainly composed of isolation circuit， short-circuit protection， overload (backup) protection circuit， 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.
When it rises，Slurry pump the outlet pipe of the submersible sewage pump does not flow or does not flow. After relevant research and ysis， we believe that there are many reasons for the following abnormalities of the sewage pump.
(d) The average maximum relative humidity in the wettest month is %. At the same time， the monthly average minimum temperature is not higher than ℃
w Submersible slurry pumpUse ultrasonic method to detect whether there is cavitation in the submersible slurry pump. This method is often convenient for re detection. Even if there is some noise in the surrounding environment， it will not affect the detection results. Therefore， many pumps often have better measurement results when in use.
X the resistance shall be greater than megohm after filling with water. Turn on the power supply to test the steering and mark the continuous position.
BHonest service Solution: Please perform parameter initialization (item F and re edit the parameter (possible cause: there is a conflict between item F and item f
vU On the basis， according to the type selection requirements of different transmission media and temperatures， it extends IRG vertical hot water circulating pipeline centrifugal pump， GRG vertical high temperature pipeline pump， IHG vertical chemical centrifugal pump， YG vertical pipeline centrifugal pump，Slurry pump ihgb vertical explosion-proof stainless steel pipeline centrifugal pump and isgb explosion-proof pipe
Pipeline single-stage single suction hot water pump. It is an IRG type single-stage single suction hot water pipeline pump with ring conveyor belt for high-temperature hot water boilers in metallurgy， chemical industry，BakersfieldQJ submersible pumpsupply paper mills， timber， restaurants textiles， bathrooms， hotels and other departments. The operating temperature is generally not more than ℃.
Mechanical seal: mechanical seal is generally used when the sealing requirements are relatively high especially in the chemical industry. It is not only required that the slurry should not leak， but also not allowed to enter the pump body. The disadvantage of mechanical seal is high cost and difficult maintenance.
Biddingy Stainless steel deep well pump can dive underground and pump hot water from deep underground. However， due to a large amount of humus and water vapor underground， it is easy to adhere to the surface of various instruments and tools，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 motor can add a variety of protection devices such as water inflow detection and overheating， so that the product can operate safely for a long time under adverse working conditions.
How to prolong the service life of the submersible sewage pumpReplace the sealing ring: after long-term use in the sewage medium， the gap between the impeller and the sealing ring may increase， so it should be replaced in time.
uAurora In this way， the upper guide housing is installed in turn. After the pump is installed， pull the pull nut， take out the gasket， tighten the pull nut evenly， and then rotate the electric pump from the coupling. The rotation must be uniform.
cZ AHR slurry pump is also a double pump casing structure， and the pump body and pump cover are equipped with replaceable corrosion-resistant rubber lining (including impeller， front sheath， rear sheath， etc.). The pump body and cover are the same as those of ah type slurry pump， and its transmission part and installation form are the same as those of ah and L type slurry pumps.
In fact， because it is designed to pump sewage or other media. Its usage is to use it in water. Both names are acceptable. When
