What are the causes of wear and tear of the isolation sleeve of acid and alkali resistant magnetic pumps?

　　Acid and alkali magnetic pump has far more than other machine pump isolation performance, one of the main reasons is that its diaphragm sleeve play a role in the transportation process will be completely isolated from the liquid closed, in terms of the operator, mastering the acid and alkali magnetic pump outer isolation sleeve wear reasons is necessary to effectively avoid abnormal operation brought about by the wear and tear of the components, to ensure that the transportation process of the stability and reliability.

　　In understanding the reasons for wear and tear of the outer isolation sleeve of the acid and alkali magnetic pump, first of all, we must know its functional characteristics, isolation sleeve and internal and external magnetic steel together to form a magnetic coupler, this component is a key part of the acid and alkali magnetic pump, is to achieve the basis of zero leakage, in the activation of acid and alkali magnetic pumps, the use of acid and alkali magnetic penetration to achieve contactless transfer of kinetic energy, magnetic force directly act and drive the isolation sleeve, from the root of the leakage to be eliminated. The possibility of leakage is eliminated from the root. However, in the actual transportation process, after using a period of time, some users also reacted to the acid and alkali magnetic pump leakage, the reason is often caused by the isolation sleeve damage.

　　Problems caused by large fluctuations in pump operating conditions: the axial force of the acid and alkali magnetic pump is automatically balanced by hydraulic equalization, in actual operation if the operating parameters fluctuations are large, it is easy to destroy the hydraulic balance of the magnetic pump, so that the sliding bearings are subjected to large radial and axial forces, resulting in damage to the bearings.

　　Acid and alkali magnetic pump production costs are high, the internal components of the material selection is very strict, outstanding quality, but if the medium is not in accordance with the prescribed standards, it is easy to cause wear and tear of the internal components, improper operation of the acid and alkali magnetic pump is one of the reasons for the wear of the outer isolation sleeve is also a very common one. Usually because of the handling of media containing a large number of hard particles or crushed iron filings, which leads to wear through the isolation sleeve, resulting in leakage, in order to avoid this situation, it is recommended to handle the media in strict accordance with the magnetic pump operating manual, avoiding the transportation of media exceeding the standard.

　　No medium or small flow rate of transport medium: make the bearing dry friction, burn the bearing. Acid and alkali resistant magnetic pump is lubricated and cooled by the conveying medium to the sliding bearings, in the absence of open inlet valve or outlet valve condition, the sliding bearings due to the lack of conveying medium lubrication and cooling and lead to damage.

　　Acid and alkali magnetic pumps can handle high-risk nature of acid corrosion of liquids and flammable and explosive gas liquids, but can not deal with more hard particles of liquids, this is because the magnetic pump is dependent on the media overflow to achieve the cooling and lubrication, if the media content of hard particles exceeds the standard, there is no doubt that it will be directly abraded through the pump, through the addition of filters in the inlet of the pump can be appropriately played a role in the protection, but should try to avoid transporting the particles of content But still should try to avoid the transportation of particle content of the media.
