During the installation of smooth bearing components, if the installation is correct the smooth oil is appropriate, the repair is timely, 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　　 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.Dandmond,　　Check the three-phase current with an ammeter on the control panel. If the phase power supply is found to be insufficient, the power supply of the submersible pump shall be turned off immediately. Check whether the cable connector, connection point and power switch contact are in poor contact and whether they are the main line. Check whether the circuit wiring is broken or loose, or whether the fuse is damaged or burnt out　　Sex is different. Although the submersible slurry pump is widely used, the impurity pump some people outside the industry misunderstand this. In fact dredging pump, desilting pump, etc. are all in the application scope of the slurry pumpYangsan,　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies, especially in the mining, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corroded　　Therefore, the correct selection of shaft seal can ensure the safe and stable operation of slurry pump.　　The submersible slurry pump may be blocked when it is used at ordinary times. In particular, some equipment is frequently used at ordinary times,DandmondZD slurry pump, but the maintenance work is not done well when it is used, so it will be blocked after being used for a period of time

　　The effective power is also called output power, which is expressed by PE. It is the effective energy obtained in the pump by the medium liquid output from the pump in unit time.　　And it shall be used according to the quota specified in the manual.　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.Installation conditions,　　Be sure to choose a pump that is more suitable for use.　　In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for use

　　Wheel, mixing impeller and other main flow passage parts are made of high wear-resistant raw materials, which are wear-resistant, corrosion-resistant, non clogging, and have strong sewage discharge capacity, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump, and the investment is lower.Analysis project,　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, so I　　In order to meet the use requirements of slurry pumps in different industrial fields and working conditions, we have continuously carried out research, development and improvement, so that we have different series, each series has a variety of specifications and models, and different series of products have different performance and s. Let&#;s learn about it below　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, protection should be done well, which should be a comprehensive optimization design method.Dandmond,　　The above four methods can be used to detect whether the submersible slurry pump has cavitation, because if the equipment is in use, it will have a great impact on the operating efficiency. Even if the cavitation time is long, it will also have a certain impact on other parts of the equipment. Sometimes submersible slurry pump　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise,DandmondSubmersible pump can pump sewage, the motor will fall into the water　　With the continuous development of slurry pump technology, submersible slurry pump appears in response to market demand. It is especially suitable for the depth at which the vertical slurry pump cannot operate. The underwater part of the vertical slurry pump is generally not more than m, the maximum design depth of our company&#;s underwater slurry pump can reach m, but such underwater depth is not the best operating depth of this kind of pump, so it will lead to the unreliability of the operation of the vertical slurry pump from time to time.
