Too high temperature and pump dry running are the direct factors that cause demagnetization. The thrust bearing is wo, causing the inner rotor and the isolating sleeve friction magnetic pump to not run for a long time under certain working conditions, such as evacuation, cavitation, high temperature, etc. So we need to pay attention to avoid all occurrences of pump idling and too high temperature. In addition, there are other degaussing reasons. If the flow is too small for a long Self-priming Surface Pumps Manufacturers time or the outlet valve is closed for too long during operation, the temperature of the inteal medium of the pump will increase, the lubrication of the pump's bearings will also become worse, and the temperature will be higher. The sleeve will be damaged after a long time. Do not pay attention to cleaning during maintenance, and iron filings are adsorbed The inner magnetism causes the isolation sleeve to wear through; 3. The axial gap between the inner rotor and the isolation sleeve is too small, causing friction and loss of magnetism. 4. There are many reasons for too high temperature. The inteal cooling/lubrication pipeline will be blocked by dirt, which will cause the temperature of the inteal and exteal magnetic cylinders to rise rapidly, and there is a possibility of loss of magnetism; 2.2019-12-27 Magnetic pump demagnetization is an easy cause of damage.. 1 5. These chemical properties affect the selection of pump materials and pump types. At this time, the corresponding disassembly and inspection should be carried out, and the parts that cause the excessive clearance should be repaired or replaced. The problem of forward and reverse rotation: whether the user will use the reverse pumping when using the gear pump, if necessary, indicate it when selecting the type, and pay attention to issues such as machine seal selection.According to different chemical pump materials, the application fields are classified as follows: 　 ,Self-priming Surface Pumps Manufacturers ...ادامه مطلب

The fiber China Surface Pumps Manufacturers is related to the 'rotor' lead of each type of pump, and the allowable fiber medium viscosity is as high as 1,000,000 mpa.The speed and flow rate of vertical single screw pump are linear, and the pump can determine the speed and flow rate. According to the requirements of the working conditions, any type of pump can be manufactured into vertical, inclined, and removable vehicle-mounted pumps.6 Mpa (60 m head) differential pressure stage, and two leads have a secondary pump pressure of 1. Vertical single screw pump performance: Lishen LG vertical single screw pump, multiple screw pump products. The flow rate ranges from 0. The output pressure of conventional products is 1. According to the user's medium and physical properties, 'stator, rotor, sheath' and overcurrent components, Shanghai Lishen has developed a relatively complete material system for selection after many years.6 Mpa (60 meters head). The single and double end face machine seals of various sealing materials of dynamic and static rings.2 Mpa ( 120 meters head). 2 The pipeline should be equipped with an independent support frame, and the weight of the pipeline should not be placed on the pump. 2. The outlet pressure is too high and exceeds the rated value. The center height of the new pump is different from the original one. 3. Tighten the bolts as required. Disassemble and polish to the required accuracy and reinstall. Recheck the gasket, re-tighten it, and tighten the diagonal bolts evenly. 3. Fix the pressure after alignment. Just open it. 3. 4. The base and the foundation ground are not fixed. No measures have been taken at the insertion end of the inlet pipe, resulting in 'bottom suction' with the bottom of the fuel tank.   ,China Surface Pumps Manufacturers ...ادامه مطلب

 The pump and the motor are directly connected coaxially, which is a mechatronics product with compact structure and stable performance. 2. The design of the anti-clogging hydraulic components of the large flow channel greatly improves the dirt passing capacity. It can effectively pass 5 times the diameter of the pump diameter and the solid particles with a diameter of about 50% of the pump diameter. 3. Reasonable design, reasonable supporting motor, high efficiency, low noise and significant energy saving effect. 4. The mechanical seal adopts hard and wear-resistant tungsten carbide, which is durable and wear-resistant, and can make the pump safe and continuous operation for more than 8000 hours. 5. The pump is a vertical structure, the center line of the inlet and outlet are on the same horizontal line, and the specifications of the inlet and outlet flanges are the same, so installation and disassembly are very convenient. 6. The area is small, and there is no need to build a machine room, which can save a lot of infrastructure costs; add a protective cover to the fan end of the motor, and the whole machine can be placed outdoors. The main purpose of the pipeline sewage pump: 1. The discharge of seriously polluted wastewater from factories and commercial units. 2. Discharge system of urban sewage treatment plant. 3. Sewage drainage system in residential area. 4. Sewage discharge from hospitals, hotels, and high-rise buildings. 5. Drainage Surface Pumps Manufacturers for subways, basements, and civil air defense systems. 6. Discharge of thin mud in municipal engineering and construction sites. 7. Water supply system of water company and factory. 8. Sewage discharge from farms or rural biogas digesters and farmland irrigation. 9. Attached machines for prospecting mines and water treatment equipment. 10. Applicable to water supply and drainage of water conservancy projects. ,Surface Pumps Manufacturers ...ادامه مطلب
