Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.　　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 inCruya, cabinet making is superfluous. It doesn&#;t seem to matter whether there is one, but now it is not. The fire control cabinet is not optional, and it is indeed one of the indispensable members of the fire protection system. Why do you say that? Now, let&#;s have a look. Why fire department　　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 andNanyuki,　　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　　; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.　　 First remove the pump from the engine.

　　 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　　Or the liquid contains fibers. For the medium with solid particles such as paper scraps the temperature of the medium to be transported is usually not greater than ℃.　　What is the order.average method,　　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, and the income has been increased.　　Adjustment. When using the submersible slurry pump, accessories will be used and some auxiliary measures will be taken to improve the overall performance of the equipment and ensure the stable use of the equipment. Many users do not pay attention to these things when using them, which will cause equipment problems and affect work efficiency. So we&#;re using　　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, 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

　　Turn on the power supply type fool operation; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.Sampling inspection,　　In this way, when the equipment is used again, the solvent in the pump is often less, and the power consumption is also less,CruyaIrrigation deep well pump, and the efficiency of the pump in use is often improved and the fact is　　Easy installation and disassembly.　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.Cruya,CruyaDrilling fluid slurry pump,　　Wheel, mixing impeller and other main flow passage parts are made of high wear-resistant raw materials, which are wear-resistant, non clogging, and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump, and the investment is lower.　　Water flow into the bearing damages the bearing.　　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.
