PiraeusCentrifugal slurry pumpPerformance and precautions during use

　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature the pressure drops to　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.Piraeus,　　 WQ series submersible sewage pump has fixed and mobile devices, as shown in the figure. When the fixed driving device is selected, the chain cable shall be separately threaded into (away from the pump outlet, and its connecting line shall be parallel to the axis of the pump outlet) two lifting eye screws or lifting plates to lift the electric pump up and down,　　The above four methods can be used to detect whether the submersible slurry pump has cavitation, it will have a great impact on the operating efficiency. Even if the cavitation time is long, it will also have a certain impact on other parts of the equipment. Sometimes submersible slurry pumpAyutuxtepeque,　　Pump, sewage submersible pump and seawater submersible pump.　　Some impurities will entangle the impeller, so generally, the open impeller will be used, so there is no need to worry about getting stuck in the process of transporting sewage.　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump,PiraeusSubmersible sewage pump, so we should follow the correct steps to connect.

　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)　　When it rises, the outlet pipe of the submersible sewage pump does not flow or does not flow. After relevant research and ysis,PiraeusSubmersible pump can pump sewage, we believe that there are many reasons for the following abnormalities of the sewage pump.　　 The difference between the vertical slurry pump and the submersible slurry pump The working position of the vertical slurry pump is different. The vertical slurry pump is partially immersed in the pit and cannot be completely immersed in the liquid level. The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pumpresources,　　 Next, it is necessary to check the water seal. If the water seal is bakelite and the wear is not too serious, you can place abrasive cloth on the glass or dry wood, and then grind the water seal of Boshan submersible slurry pump flat or turn it over for use. However, if the thrust rubber water seal is used,PiraeusSubmersible slurry pump, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.　　The higher the specific speed of submersible slurry pump the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.

　　In the mud pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, and the resultant force is the sum of the two forces. If the submersible slurry pump is equipped with an auxiliary impeller,　　If the water leakage is serious, the broken pipe shall be dismantled and replaced. Lower the lift and press the nozzle of the water pump into the water for .m.　　The sewage pump will leak. If the water pipe leaks, it will reduce the power of the water pump and even damage the sewage pump. In case of fixed installation, it shall be applied on the pipe to avoid leakage. Pages can be welded by electric welding, buried in the soil, coated with asphalt, and then should not be gassed. Steaming of tap water products　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, the application market of submersible slurry pump is also better than that of vertical pumpPiraeus,　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used, so that they can have good wear and corrosion resistance when they are used, and can be used to transport most of the media when they are used. Phreatic slurry　　 for screws that are too tight or rusted for a long time, the nut can be lubricated with kerosene prepared in advance, or the nut can be gently knocked with a wooden hammer and then removed. This method can also be used in slurry pumps and other places.
