Application of pumps in chemical industry

With the development of China’s industry, chemical research industry, etc., Chinese enterprises can compare the variety and structure of pumps used in the chemical management industry, and can introduce a lot of information technology, technology, performance and product service quality have been greatly improved. The negative pressure pump is a micro vacuum pump. Because it has one intake and one exhaust nozzle and one exhaust nozzle, and can continuously form vacuum or negative pressure at the inlet, a slight positive pressure is formed at the exhaust nozzle. The evaporator circulation pump is a large flow, low head axial flow pump, which is specially used for the forced circulation of evaporators in ammonium phosphate, phosphoric acid vacuum salt production, alumina, caustic soda, light industry and other industries. Sanitary centrifugal pump is one of the simplest equipment parts. Its purpose is to convert the energy into velocity or kinetic energy and pressure of the fluid being pumped and then into an electric motor or engine. At present, there are more and more manufacturers of vacuum discharge pumps in China, but compared with the products used in the chemical company industry, there are still many national gaps in our country.

1. Requirements for pumps in the process of chemical safety production and operation. Students transport media: In chemical industry production, vacuum discharge pumps are used to transport clean media such as water, oil or other non-materials. In these two aspects, it is relatively simple to analyze through design and use. But the performance issues of mechatronics vary with the type and nature of the chemical reaction medium being transported. In most cases, chemical media refers to the use of some media that are very harmful to society. The transported media are volatile or low temperature, or are more corrosive. At the same time, they meet the requirements of strict sealing and do not allow leakage. With the huge changes in people’s learning time and wear, its sealing performance will also change, and the leakage will increase. The variety of chemical media conveyed derives the variety of requirements for vacuum discharge pumps.

1. Changes in construction process parameter data during chemical production activities require pumps without any process cost control ability in chemical production and life processes. It cannot be completed in a more stable and unchanging process. During the process, changes in conditions such as weather, raw materials, etc. may affect the stability of the entire system. Regulation is a means of chemical production to find a relatively balanced point in continuous self-regulation to achieve the stability of the system. In all the adjustment teaching process, the vacuum discharge pump is indispensable. In the process of adjustment, the vacuum discharge pump has to withstand the requirements of continuous efforts to change the flow, pressure, current and temperature range, which makes it necessary to install variable speed electric vehicle drives at key positions in the production process. The characteristic curve of different vacuum discharge pumps adjusts the working status of the pump to match the conveying medium demand required by the technological level, so as to achieve a stable operation state of automatic control of the parameters of chemical production with good effect.
