How to improve the anti-corrosion and heat preservation effect of the desulfurization pump?


Desulfurization pumps are used in many industries, and the effects are obvious to everyone. Especially used in some places with harsh environments, such as some places with acid and alkali, corrosive or some toxic fumes. Although the desulfurization pump is designed for the production of corrosive service locks, it is often used in these harsh environments, and it will cause some damage to the pump itself. Therefore, timely maintenance is very important. Due to the many components involved in the operation of the desulfurization pump, especially the transmission parts, impellers, shaft seals and other components are very important.

The anti-corrosion and heat preservation of the desulfurization pump plays an important role in the work of the pump. Everyone knows that the pump's transport medium is mostly corrosive, and the medium temperature is different, the degree of corrosion is different, how to improve the anti-corrosion and heat preservation effect of the desulfurization pump?

Anti-corrosion is the primary problem of desulfurization pump. It should be carried out according to the operating rules during the use of desulfurization pump. This can improve the working efficiency and service life of the desulfurization pump, and also effectively reduce the leakage caused by mechanical failure caused by misoperation. Leakage accidents reduce corrosion problems in equipment. The desulfurization pump itself has good corrosion resistance characteristics, as long as we usually do not damage it, pay attention to the environmental conditions.

There is also the protection against induced corrosion of AC transmission lines. Generally speaking, the corrosion caused by AC is much smaller than that of DC, which is about 1% of DC. However, when the high-voltage AC transmission line is erected in parallel with the pipeline, due to the influence of the electrostatic field and the alternating magnetic field, the alternating current is induced by the metal pipeline. At this time, the influence and harm to the pipeline cannot be ignored, in the case of AC/DC superposition. The presence of alternating current can cause depolarization of the electrode surface and accelerate corrosion. In addition to avoiding or shortening the length of the parallel segments as much as possible.

Insulation measures for desulfurization pumps are also essential, especially in low temperature weather. If the desulfurization pump is a closed storage device, it is necessary to insulate the delivery line and the valves at each joint. If it is an open storage tank, it is necessary to effectively control the surrounding environment to remove flammable and explosive objects, so that the periphery of the storage tank can be warmed to ensure that the medium will not solidify.
