NebaUsed pipeline pumpWhat should I pay attention to when buying

　　 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.　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand,NebaBaigang deep well pump, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition,　　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　　When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation,NebaVertical multistage centrifugal pipeline pump, that is, the traditional slurry pump cannot be installed and operated, and the submersible slurry pump can supplement this part of the blank work point.　　After that, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.　　Sex is different. Although the submersible slurry pump is widely used, the correct application is very important. Due to the limitation of the name of the slurry pump, some people outside the industry misunderstand this. In fact the impurity pump, dredging pump,NebaQuotation slurry pump, desilting pump, etc. are all in the application scope of the slurry pump

　　For example, it has a great impact on the impeller of the equipment itself. So how to detect whether the equipment has cavitation during use?　　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.　　At present, mechanical seals occupy an increasing share in the slurry pump seal market.Where can I find it?,　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.　　 The slurry pump mainly aims at conveying flow, so the flow meter (meter) shall be installed in the operation monitoring system as far as possible to monitor whether the flow meets the requirements at any time; In the pipeline system slag flushing system and pressure filtration dehydration system equipped with hydrocyclone, the nut can be lubricated with kerosene prepared in advance certain　　 for screws that are too tight or rusted for a long time, 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.

　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.High quality brand,　　Many users, including new practitioners of slurry pumps, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar, but there are essential differences. What is the difference between submersible slurry pump and vertical slurry pump?　　 Store in a well ventilated and dry place. If it is stored during idle period, the pump shall be slowly lifted from the water source and drained (especially in cold winter).　　The packing seal, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role inNeba,　　The type selection planning of submersible slurry pump has a great impact on its service life and operation stability. A scientific and reasonable type selection plan will affect whether the slurry pump can achieve efficient operation. The operating power of the slurry pump is very high and the loss is small. Service life of flow passage parts of pump　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized to　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.
