Precautions for Selection of Acid and Alkali Resistant Pump

Basic Selection of Acid and Alkali Resistant Pumps

  Acid and alkali resistant chemical pump is a wide range of general-purpose mechanical equipment, it is widely used in petroleum, chemical industry, power metallurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, occupying an important role in the national economy Status. According to statistics in 1979, the output of acid and alkali resistant pumps in my country reached 1.256 million units. The electric energy consumption of acid and alkali resistant pumps accounts for more than 21% of the national electric energy consumption. Therefore, greatly reducing the energy consumption of acid and alkali resistant pumps is of great significance for energy saving.

  In recent years, our acid and alkali resistant pump industry has designed and developed many high-efficiency and energy-saving products in acid and alkali resistant chemical pumps, which have played a positive role in reducing the energy consumption of acid and alkali resistant chemical pumps.

  However, in various fields of the national economy, due to unreasonable model selection, many acid and alkali resistant pumps are in unreasonable operating conditions, operating efficiency is low, and a lot of energy is wasted. Some acid and alkali resistant pumps cannot be used at all due to unreasonable selection, or increase in maintenance costs and low economic benefits. It can be seen that the rational selection of acid and alkali resistant pumps is also of great significance for energy saving.

  The so-called rational selection of acid and alkali resistant pumps is to comprehensively consider the comprehensive technical and economic indicators such as the investment and operating costs of acid and alkali resistant pump units and acid and alkali resistant pump stations, so that they conform to the principles of economy, safety and application. Specifically, there are the following aspects:

  1. It must meet the requirements of flow and head, that is, the operation time point of the acid and alkali resistant pump (the intersection point of the device characteristic curve and the performance curve of the acid and alkali resistant pump) is often maintained in the high-efficiency range, which saves power and is not easy Damage to the machine parts.

  2. The acid and alkali resistant pump should not only be small in size, light in weight, low in cost, but also have good characteristics and high efficiency.

  3. It has good anti-cavitation performance, which can reduce the excavation depth of the acid and alkali resistant pump house without causing cavitation of the acid and alkali resistant pump, so it runs smoothly and has a long life.

  The above is the sharing of notes on the selection of acid and alkali resistant pumps. In the next chapter, we will bring the selection steps of acid and alkali resistant chemical pumps. If you have any questions, please contact us and we will serve you wholeheartedly!
