Abu DhakaRubber lining submerged slurry pumpWhat points should be paid attention to in seasonal work

　　It, generator and market formed at the beginning of construction have gradually formed a certain scale after more than ten years of rapid development. In the early stage, in order to meet the needs of market development,Abu DhakaSingle suction slurry pump, generators and other mechanical and electrical products were collectively moved to the phase II market for operation. With a good business environment, water pumps and generators　　 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 damagedAbu Dhaka　　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　　The pump should be divided into two aspects: electricity and machinery. As for machinery, 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 sealBrezno,　　Start the priming pump. Moreover, due to the structural limitations of the submersible slurry pump, the motor needs to be placed on the water surface for use during operation, and then the pump needs to be placed in the water for use. Therefore, the submersible slurry pump must be　　 Move the sand pumping site frequently. When the pump pumps sand at a fixed position and drops to a certain height, lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand so as to move the sand pumping place back and forth for sand pumping, so that the sand pumping area in this area forms a honeycomb,　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.

　　 Another possibility is that the gas is sucked in when the pump is in use.　　AHR slurry pump is also a double pump casing structure, and the pump body and pump cover are equipped with replaceable corrosion-resistant rubber lining (including impeller, front sheath, rear sheath, etc.). The pump body and cover are the same as those of ah type slurry pump, and its transmission part and installation form are the same as those of ah and L type slurry pumps.　　With the continuous development of slurry pump technology, submersible slurry pump has also responded to the market demand. At the same time, 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 exceedsApplication process,　　 First of all, most of the pumps are suitable for conveying some relatively clean media,Abu DhakaCarbon steel explosion-proof pipeline pump, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may　When using the submersible slurry pump, the equipment may be burned out. The main reason for this phenomenon is improper operation. How should we prevent the burning out?　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller), magnetic dial indicator, outside micrometer, caliper, feeler gauge, square ruler, screwdriver with handle, hammer, V-shaped irons of the same specification, clean kerosene, oil basin, cotton yarn etc.

　　Submersible pump is a common water lifting equipment for deep wells. During operation, the whole machine intrudes into the water to extract water from the underground to the surface. It is commonly used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersibleagent,　　Water pump is a kind of machinery that pumps energy liquid. It is a machine that converts the mechanical energy of the prime mover into the potential energy of the pumped liquid. Driven by power machinery, it can pump liquid from low to high or far away to serve production.　　 water　　 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, drive the solid flow, and realize the transportation of slurry.Abu Dhaka,　　 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 adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press the　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.　　Submersible slurry pump shaft seal type: packing, packing and auxiliary impeller seal, mechanical seal
