Organic Buckwheat (Fagopyrum esculentum), also known as Common Buckwheat, Japanese BuckwheatandSilverhull Buckwheat, is a plant cultivated for its grain-like seeds and as a cover crop. A related and more bitter species, Fagopyrum tataricum, a domesticated food plant common in Asia, but not as common in Europe or North America, is also referred to as buckwheat.
Despite the name, Organic Buckwheat is not related to wheat, as it is not a grass. Instead, Organic Buckwheat is related to Sorrel, Knotweed, and Rhubarb. Because its seeds are rich in complex carbohydrates, it is referred to as a Pseudocereal.

The urgent problem to be solved now is: What are the requirements for users of chemical pumps for future chemical pumps? This article will respond to this question of concern.
A prominent feature of mechanical products used in the chemical industry is that the performance and requirements of mechanical products vary with the type and nature of the chemical medium being transported. Although the medium mentioned here is sometimes referred to as water, oil or other non-hazardous substances; in most cases, the chemical medium refers to some very scary chemical raw materials; for example, some seriously harmful media (poisonous, Corrosive and flammable medium; especially some media that are prone to chemical reactions, corrosive, erosive or solid or gaseous media containing the above ingredients. Changes in chemical composition and chemical element ratios in diversified media can lead to changes in the properties of chemical media; resulting in increased concentrations of chemical media or special flow properties (eg, diffusible media, polymer solutions, etc.). Therefore, the stringent quality requirements for the purity of chemical media (GMP, polymers, electrolytes, etc.) are often imposed, and these particularly stringent quality requirements can be conveniently achieved by suitable chemical pumps.
The diversity of chemical media is derived from the diversity of chemical media. This makes it difficult to become a simple standard system for the chemical pump standard system. Compared with other fields, such as household electrical, home heating, water supply, drainage, etc., as well as chemical refining or automobile manufacturing, standardization has not reached a standard level not only in the production of products but also in the use of products. In chemical production enterprises, chemical pump standardization has encountered obstacles in terms of technology and economy.
Where is the possibility of optimization and improvement of chemical pumps?
There is no doubt that standardization is very helpful and very meaningful for the production and use of chemical pumps. However: From the perspective of the cost of life cycle, what should the standardization of the Zui economy look like? Is it a detailed standardization of long-term optimization according to various specific use cases? Still a rough standardization? When will the obstacles to standardized investment that can be recovered over a longer period of time brought about by the adoption of new technologies and the development of new products will end? How can we make a unified understanding of the standards of chemical pumps without compromising the interests of either the chemical pump production plant or the chemical pump producer? These questions can only be answered by strengthening the dialogue between chemical pump manufacturers, industry associations and chemical pump manufacturers. Possible solutions are: from the user's point of view, for example, establishing long-term strategic partnerships with suppliers; establishing different levels of standardization at different levels of clear definition (eg chemical pump structure types, suppliers, series, Materials, configuration, etc.) and integrated modular structure.
But Zui is also important to the "lifetime cost" problem. The potential of chemical pump life has not been fully exploited. Why does this happen? Among the many possible answers, one answer is for everyone: due to the different requirements for chemical pump performance parameters, the allowable life of the chemical pump, the load that can be tolerated, and so on. The procurement cost of the chemical pump, the installation cost, the energy consumption of the chemical pump, and the maintenance cost are relatively easy to calculate. However, the estimation of chemical pump maintenance costs is relatively difficult to determine: because the failure and possible damage of chemical pumps are not determined by the pump itself, it is often subject to changing chemical media being transported and subject to special conditions of use. Using the experience of a certain chemical pump that has been mastered, the estimation of the maintenance cost of another chemical pump often has great limitations, and the estimated result can only be an approximate, thick-line estimate.
Especially in a single equipment that works continuously, in equipment that has little "surplus" during working hours and "buffering capacity, intermediate storage" in production engineering, in equipment that sells short-term products that are in short supply in the market and sales. In chemical equipment with high profits, the failure of the chemical pump system and the resulting reduction in the service life of other chemical spare parts will result in a doubling of the overall maintenance cost.
It must be pointed out that this "special case" is not a general law and is not an unsolvable problem. After many dialogues and negotiations between chemical pump users and production plants, such problems can often be solved. The quantification of chemical pump maintenance costs is still difficult due to the small amount of data that can be mastered and the many undetermined use boundary conditions. People can't make accurate risk assessments of chemical pumps; but people can consider the cost of repairing chemical pumps to reduce procurement costs or reduce energy use costs. It is an abnormally important tool to compare and analyze the technical performance of different chemical pump systems as much as possible and as accurately as possible to judge the cost of the chemical pump life cycle.
Replace the spare chemical pump system by monitoring the working state of the chemical pump system
The overall cost and the cost of chemical pump life are a common consideration for chemical industry companies: as long as the input costs are not too high, they can use more economical single equipment or instruments, ensure effective chemical production and have chemical equipment. Operating the monitoring device, users of chemical equipment will abandon the investment plan of the spare chemical pump system. In order to ensure that the chemical pump can meet the requirements, a large number of measures must be taken in the initial stage of considering the chemical equipment plan, in the formulation of special technical specifications and the production and assembly of chemical pumps. During the use of these chemical pumps, the operation of the pump and the flow of chemical media through the chemical pump are continuously monitored by the chemical pump system, which not only improves the availability of the chemical pump, but also enables the chemical to be efficiently and economically obtained. Information on pump maintenance status.
This enhanced function of the chemical pump can be achieved by installing vibration sensors, pressure sensors, temperature sensors and solid noise sensors and their accessories in the pump body, by adding leakage monitoring devices for sliding bearing seals and chemical pump bearing diagnostic devices. The chemical pump performance diagnostic control system or the performance diagnostic controller of the frequency converter is implemented. In addition to the above-mentioned technological advances, the next development trend of chemical pumps is to improve the "friendly use performance" of chemical pumps according to the requirements of users; to produce more affordable products. Please also pay attention to the following questions when you want to improve the pump products used in chemical companies:
1. Generally speaking, modern chemical equipment is mostly highly automated and has a high production capacity. In these modern chemical production equipment, all the new chemical production data and information of the Zui, the current working status data and information of the chemical equipment can be displayed on the large screen in the production control room, and the chemical can be processed according to the production needs. The process is properly adjusted and controlled. According to experience, the early diagnosis of chemical pump failure and the connection between the chemical pump working condition monitoring system and the entire chemical equipment are often the focus of maintenance and repair in actual application, and also the high maintenance cost; especially in the technical transformation of old chemical equipment. When investing in chemical pump monitoring and early failure alarm systems, the cost is high. Modern information technology, such as WLAN network communication and bus communication technology, not only provides technical and economic benefits, but also provides considerable potential for optimization of chemical pump systems. However, for the existing old-fashioned chemical production equipment equipped with traditional detection and adjustment technology, please consider the appropriate and economical monitoring and diagnosis system.
2. According to the ever-increasing variety and complexity and the increasing number of chemical pump series (pumps, bearings, seals, chemical pump drives or adjustments, etc.) that are suitable for a particular working condition. It is conceivable that an integrated, modular chemical pump construction would be a very important structural design. It not only has good technical performance, but also brings good economic benefits.
3. In addition, it is also very meaningful to reduce the throughput of chemical equipment operators to produce initialization data (eg, vibration speed, sum or temperature, etc.). It is recommended to replace a large amount of data flow with a suitable data processor. In dealing with the data conversion of chemical pump systems and chemical production equipment, based on past experience: good cooperation between system suppliers and chemical equipment operators is required.
Can the chemical pump system be used as a sensor and regulator?
In the chemical industry, users of production equipment often say a buzzword: "Replace the sensor with a chemical pump system." Moreover, the "sensor" here not only checks and controls the medium flow when the chemical medium is input; but also as the "sensor", it must monitor the state of the chemical medium and monitor the corresponding work control points. When the physical properties or chemical composition of the chemical medium being transported changes, the working control status and operating conditions of the chemical equipment (zui small load, overload, amount of gas to be transported, vacuum degree, etc.) should be integrated into the chemical pump casing. The sensor on the body directly obtains accurate data. The purpose of this is to minimize the additional monitoring equipment in the chemical equipment. At present, the integration of this chemical pump system has made certain progress: the chemical pump system has considerable adjustment capability and has become a chemical process regulating component; a large number of electric drive devices for controlling powerful and variable speed. In addition to high energy efficiency, this variable speed drive system can also adjust the working state of the pump according to different chemical pump operating characteristic curves, so that the chemical pump work can be matched with the medium input requirements of chemical equipment. However, in the actual production of chemical equipment, there is still a certain difficulty in realizing the fact that the complex chemical pump characteristic curve and the complex chemical equipment characteristic curve should be matched to ensure the variable speed. Drive equipment can work well and requires extensive communication and information exchange between chemical pump manufacturers and chemical equipment users.
When planning and developing chemical equipment, it is necessary to start thinking about whether to adopt a variable drive system. Because it is not in any chemical production process, the variable speed automatic drive is a good choice. In addition to some technical standards (such as: the slope of the equipment characteristic curve, the rigidity of the chemical pump characteristic curve, the seismic performance reserve of the drive, etc.), in principle, it must also be based on various specific use conditions, according to the service life of the chemical pump. High and low economic evaluation.
In principle, Zuijia's chemical industry pump should have the characteristics of high quality, high reliability and high environmental protection performance; it is also beneficial to the health of workers while completing the task of chemical medium transportation; the expected service cost Zii low; can be integrated with the entire set of chemical equipment into a whole. However, in the chemical production process, various specific conditions of use and purpose of use have put forward various requirements for the manufacture of chemical pumps.
