The anticorrosion and heat preservation of the pump are very important for the work of the pump. Everyone knows that most of the pump's delivery medium is corrosive, and the temperature of the medium is different, and the degree of corrosion is different. How to improve the anticorrosion and heat preservation effect of the pump?
Anti-corrosion is the primary problem of the pump. It must be performed in accordance with the operating rules during the use of the fluoroplastic pump. This can improve the working efficiency and service life of the pump, and can also effectively reduce leakage and leakage caused by mechanical failure caused by misoperation Leakage accidents, reducing equipment corrosion problems. Fluoroplastic itself has good corrosion resistance, as long as we usually pay attention not to damage it, pay attention to environmental conditions.
There is also protection against induced corrosion of AC power lines. Generally speaking, the corrosion caused by AC power is much less than that of DC power, which is about 1% of DC power. However, when high-voltage AC transmission lines are erected in parallel with pipelines, AC currents are induced in metal pipelines due to the effects of electrostatic fields and alternating magnetic fields. At this time, the effects and hazards on pipelines cannot be ignored. The presence of alternating current can cause depolarization of the electrode surface and accelerate corrosion. In addition to avoiding or shortening the length of parallel sections as much as possible.
Insulation measures are also necessary, especially in cold weather. If the equipment is a closed storage equipment, the mixed-flow pump manufacturer must perform insulation treatment for the conveying pipeline and the valves at each connection. If it is an open storage tank, it is necessary to effectively control the surrounding environment, remove flammable and explosive objects, and ensure that the medium will not solidify.
The conditions for users to choose anticorrosive pumps vary greatly. For example, they are classified according to the chemical properties of the medium: there are acids, alkalis, solvents, strong acids, and strong bases, as well as weak acids, weak bases, and mixed acids. Status points: clear liquid, slurry, low viscosity, high viscosity, different solid content, solid particle size, solid hardness, material specific gravity, material sedimentation performance, etc. If it is divided according to working conditions: there are different inlet slot heights, different suction strokes, different pressures, different flows, different operating conditions (long-term, intermittent, pressure, etc.) and so on. Therefore, the selection conditions of anticorrosive pumps are very complicated. The above three conditions of use sometimes exist independently and sometimes coexist. Therefore, the selection of pumps is very difficult. So in general, different types of working conditions require different types of anticorrosive pumps to match.
