MesaSubmersible sewage pumpAnalytical principle of frequency conversion energy saving

　　 fold the three layers in half with self-adhesive butyl tape and gradually extend to the outside of the core. When winding, the tape shall be stretched twice, and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.　　 Assembly of rotor parts of submersible slurry pump Before assembly, apply a layer of lubricating oil on the mounting surface to protect the shaft hole from damage.Mesa, 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　　During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests, the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, we use it at ordinary timesYerba Buena,　　The of descending axial force can be used for slurry transportation in power plants,MesaQuotation slurry pump, hydraulic and other professions; The mechanical seal is tight and reliable, and the leakage probability does not exceed drops /min, which is mostly used to transport flammable explosive, toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.　　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)　　Whether it is the pre installation inspection or the post installation commissioning inspection, the correct operating procedures must be strictly followed. Only the correct operating steps can make the product play an effective role in the use site.

　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.　　Replace the motor shaft of the water pump.　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by η Indicates.Free consultation,　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining, stainless steel, titanium alloy and other materials used in China&#;s mining, chemical and water conservancy projects on the Yellow River are prone to wear short service life and many faults　　 if the removed gasket is seriously damaged, a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.　　 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, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pump

　　Circumference. In the application of slurry pump, we must pay attention to reasonable design, which are very important. In addition to the main wheel, a set of stirring impeller is added at the bottom of the product, which can spray the precipitated slag into a mixture of water and solid particlestotal cost,　　 in addition,MesaPipeline pump body, the noise method directly detects the noise of the equipment in the detection process, so in fact,MesaISG single stage vertical pipeline pump, such measurement is not very accurate.　　And it shall be used according to the quota specified in the manual.　　 In addition, the noise method directly detects the noise of the equipment in the detection process, but this measurement will also be affected by the surrounding noise, so in fact, this measurement is not very accurate.Mesa,　　 Moreover, the processes of these two pumps are also different, and the sewage pump can generally be adjusted. Submersible pumps are generally used in some special or other places.　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.　　The installation of submersible slurry pump is a step that needs to be concerned. Since we all care about it, it is mainly because the installation will directly affect the use effect. The installation work should be seamless. Some key operating points can be seen when installing the slurry pump.
