Selection of anti-corrosion pump often exist in the following situations: one is for the sake of saving, the similar working conditions all the models unified to the same model, specifications, in order to facilitate future management, such as the standby pump scheduling, spare parts interchangeability Good, which can also reduce the inventory of spare parts to achieve the purpose of saving money. The disadvantage is that some of the pumps are reluctantly used together, will have a horse-drawn car, functional waste; or pump performance or function does not match the actual needs, resulting in equipment damage, or maintenance costs increase. Often things are against their wishes: This would like to unify the specifications pump, save costs, but the result is increased damage, frequent maintenance, the cost increases. Another method of selection is just the opposite, because of different conditions, that is, the pump model, a high degree of breakdown of the specifications, resulting in increased spare parts, inventory increases, the increase in capital more than three phenomena. The existence of the above two situations is now more common. They have their own strengths, but they also have their own shortcomings. The method we adopt depends on the actual situation. We do not agree with the over-uniform specification model nor the over-detailed specification model depending on whether it is conducive to production, management, Conducive to cost savings, if you can meet the three requirements are conducive to the use of a unified model selection method, the reverse is not true. Selection Example: Wet smelting enterprises, often for convenience, the ordinary slurry pump used as a filter press with the pump, so that although the convenience of management, reducing the cost of the first purchase, the spare parts and spare parts to facilitate the procurement and storage, However, due to the normal process pump to press the pressure operation, the seal can be easily damaged, in this case, filter press pump operation is often difficult to normal, the result is to facilitate the management has increased maintenance costs. Therefore, at this time, filter press should be used for differential pump selection, can not figure convenient.
