Another possibility is that the gas is sucked in when the pump is in use.　　 Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation, the motor shaft drives the water pump impeller to rotate, and transmits energy to the slurry medium to generate a certain flow rate, and realize the transportation of slurry.Exhibitor,　　Belt drive shaft seal: the pump seal can be divided into three types: packing seal, auxiliary impeller seal and mechanical seal. The packing seal and the secondary impeller seal will drip during the operation of the pump. Mechanical seal can make no water leak.　　Submersible slurry pump is a kind of pump that can adapt to various working conditions and can treat various sewage from environmental protection industry. Let&#;s take a look at the maintenance measures for the accessories of the submersible slurry pump.Location This Zalafah,　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.　　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)　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.

　　 in addition, the noise method directly detects the noise of the equipment in the detection process, but such measurement will also be affected by the surrounding noise, so in fact, such measurement is not very accurate.　　Pipeline pump, belonging to the category of centrifugal pump, is a single-stage centrifugal pump with standing structure. Because the layout design of its water pump inlet and outlet is relatively special, they are all located on the same straight line, and their inlet and outlet diameters are the same the overall description is similar to a section　　 If there is no corresponding water leakage sensor, it is necessary to regularly maintain the submersible slurry pump and replace the seals.Professional is king　　Do not exceed the rated current.　　 Precautions for disassembly of submersible slurry pump Before disassembling the filter press, drain the lubricating oil in the rotor bearing housing. If the newly added oil is stored make sure that the liquid in the submersible slurry pump is completely discharged. If the rotor is disassembled, it should continue to be used after maintenance. Do not dump it directly　　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, for example, the pump lift used is too high or too low, which will lead to overload, so we are selecting the pump

　　 the submersible slag pump is often used to transport pulp containing solid particles, so the wear resistance of the pipeline should also be considered.Packaging strategy, it has a great impact on the impeller of the equipment itself. So how to detect whether the equipment has cavitation during use?　　 touch method: touch the pump to monitor the changes of temperature, vibration and clearance,ExhibitorWQ submersible sewage pump, so as to judge whether the pump is faulty.　　Screw it down, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.Exhibitor,　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because　　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.　　First, the submersible slurry pump is also a vertical slurry pump, because its axis is basically vertical when it works, but it can be completely immersed in water when it runs, so it is a good choice
