Black spotWQ submersible pump parametersBring changes to the domestic market

　　 First of all, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may　　 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 pumpBlack spot,　　That is, first, check whether the equipment operation noise is reasonable; second, check whether the alarm unit has leakage and overheating alarm signals; third, record the flow and current of the water pump operation. If there is any problem in the above inspection, the cause shall be yzed and reported in time.　　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.Biarika,　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition, compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor and　　With the continuous development of slurry pump technology, submersible slurry pump has also responded to the market demand. At the same time,Black spotSmall deep well pump, this type of pump is especially suitable for the depth where the vertical slurry pump cannot operate. Pay attention when using the equipment. The submersible slurry pump can operate if its depth is less than m but it exceeds　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump, tighten the adjusting screw of the bearing box evenly, and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race,Black spotSubmersible sewage pump, bearing gland and retaining sleeve　　For example, the lubrication method, the number of impellers, the number of bolts and other small details determine that these slurry pumps are not used.　　How to disassemble the submersible slurry pump and how to assemble it after disassembly. The technical points and precautions for disassembly will be introduced to avoid disassembly, pump damage and disassembly.Test conclusion,　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump, loosen the bolts pressing the bearing box, loosen the adjusting nuts, make the bearing components move forward, you can compare the previous maintenance records. The second is electricity. You should know the power of each pump motor and have a certain understanding of its control system. Slurry pump with mechanical seal　　In this way, when the equipment is used again, the solvent in the pump is often less and the power consumption is also less, and the efficiency of the pump in use is often improved, and the fact is

　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakageQuality Assurance,Black spotCarbon steel explosion-proof pipeline pump,　　 The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.　　Attachment: data sheet required for ordering deep well pump　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.Black spot,　　In this way, a smooth surface can be formed on the surface.　　Pressure. Therefore, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.　　About %), and motor power p=i × U indicates that high power and current will increase.
