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)　　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.Cobstein,　　 Check whether there is a problem with the ventilation system: check whether the fan is damaged, whether the fan rotates correctly, and whether there are abnormal objects blocking the ventilation holes.　　Superior, complete protection s, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.Namdinh　　 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power　　Be sure to choose a pump that is more suitable for use.　　Pressure. Therefore, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.

　　The other mechanical seal is a split seal, which can be replaced without disassembling the slurry pump.　　 The variable speed operation of screw pump is used in sewage plants. Screw pump is generally used together with sludge dehydrator. Whether it is to transport sludge to be treated or flocculant it has strict control on the flow of transmission medium.　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the continuous working time, the number of stops and starts of the pump,CobsteinVertical slurry pump,CobsteinCarbon steel explosion-proof pipeline pump, the surrounding environment and the working temperature. Therefore, it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.Quotation sheet, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.　　 During the installation of smooth bearing components, if the installation is correct, the smooth oil is appropriate, the repair is timely, and the delivery life will be long, the repair personnel should regularly repair the bearing components, check the condition of the bearings and the smooth oil, and regularly add or replace the smooth oil during the work, and the interval and write　　The premise of using this method is that the water gun must have sufficient flow during use, otherwise the effect of the submersible slurry pump may not be obvious.

　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damagedQuality inspection report,　　The vertical sand pumping pump is popular with a wide range of sand pumping pump users because it is easy to move. This equipment is made of high-tech endurance data. Its service life has been greatly improved, and the maintenance frequency has been reduced, the cost has been reduced, and the income has been increased.　　When assembling the motor and water pump departments below grade , firstly, tighten the nuts evenly between the water inlet joint and the contact plane from the upper part to the bearing seat, install the coupling pump shaft, fixed studs and lock rings, fix the impeller and conical sleeve on the pump shaft with a damp cylinder, and install the guide housing and impeller　　Slurry pump Inappropriate model is selected when selecting the pump. In actual use, when the load conditions do not match the model of the slurry pump, the pump lift used is too high or too low, which will lead to overload, so we are selecting the pumpCobstein,CobsteinLong shaft submerged slurry pump,　　The of descending axial force can be used for slurry transportation in power plants hydraulic and other professions; The mechanical seal is tight and reliable, and the leakage probability does not exceed drops /min, explosive, toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.　　It is an auxiliary means of on-site monitoring. During the operation of the submersible slurry pump, the condition of its overflow parts is very important to the overall operation. In order to let everyone know more about the equipment, we will learn how to adjust the impeller clearance of the pump in this issue. I hope it will help you.
