supply Ordinary vertical centrifugal pump What are the requirements for backfilling after installation? 1. Before backfilling, check that the pump station has not suffered structural damage. If yes, please contact our company as soon as possible and do not dispose of it by yourself! 2. After completing the installation and grouting of the pump station on the cement base plate and reaching the required strength, check that the structure is intact, and then backfill can be carried out. three Ordinary vertical centrifugal pump manufactor Backfilling must be carried out in time after installation to prevent the pump station from floating and toppling, and the FRP material cannot be pulled or squeezed by force. 4.32mm plain soil can also be backfilled with graded sand and gravel, and the particle size of gravel shall not exceed 32mm. When the distance between the pump station barrel and the edge of the foundation pit is less than 1 m but more than 0.5 m, only graded sand and gravel can be used for backfilling, and the gravel particle size shall not exceed 32 mm. When backfilling in winter and rainy days, check whether the backfill materials are stuck together. The backfilling of the foundation pit shall be carried out continuously and completed as soon as possible. During the construction, the ground water shall be prevented from flowing into the foundation pit to avoid slope collapse or damage to the foundation soil. Backfilling shall be carried out in layers. The height difference of each layer shall not exceed 50cm. It shall be compacted with a tamper or manually, and the compaction shall be more than 90%.

In recent years, with the construction of more and more pump houses around the country, problems related to them have become increasingly apparent, Ordinary vertical centrifugal pump manufactor Management and maintenance, water pollution, safety management and other issues are gradually exposed. How to further strengthen the management level of the above pump room facilities and equipment, further improve and ensure the safe water supply capacity, and manage and maintain all kinds of facilities and equipment in the pump room has become the common concern and work direction of all major water supply management enterprises and water supply equipment manufacturers. Standardized standard pump room construction and management introduced, supply Ordinary vertical centrifugal pump Mainly based on the optimized configuration and construction of various facilities and equipment in the pump room, the computer network information technology is used to organically integrate various nodes in the pump room. At the same time, in combination with the local economic construction level, according to the actual situation and budget needs of the project, a reasonable standardized construction, management and maintenance scheme is provided and implemented for various pump rooms. Its core is the safe full frequency conversion control pressurization equipment, followed by the integration of computer network information system, and the safety management and maintenance of the whole life cycle.

supply Ordinary vertical centrifugal pump There were few original cast-in-place operations on the site, and the health did not disturb the residents. From then on, we bid farewell to the "gray and hazy" construction site. In addition, the reuse rate of steel formwork and other materials has been improved, and the waste, loss and energy saving can be reduced by more than half. It can be seen that, Ordinary vertical centrifugal pump manufactor It makes up for the shortcomings of the existing reinforced concrete operation, and the quality of the houses is also very good, which is acceptable to the public. Think about the future when prefabricated housing becomes the main construction industry in China, there will be no more dust flying around the construction site and no more construction waste everywhere. At present, the environment in our country is getting worse and worse. It can be seen that the energy-saving pump room is not only good, but also very promising.

supply Ordinary vertical centrifugal pump It is not only reflected in its working ability, but also in its excellent manufacturing process and maintenance costs. The integrated prefabricated pump station is highly integrated, so its volume is very small. It is a good choice for sewage treatment equipment for some factories and business districts that do not have a shortage of land. In addition, Ordinary vertical centrifugal pump manufactor The degree of intelligence is very high, so its failure rate is very low. Combined with the application of anti blocking technology, the integrated prefabricated pump station becomes very convenient in the later use, which greatly reduces the labor cost and maintenance cost.

supply Ordinary vertical centrifugal pump "Good, fast and economical" Talking about the advantages of prefabricated pump house, Ordinary vertical centrifugal pump manufactor He said, "First of all, the quality of prefabricated concrete components is controllable, the deviation of appearance surface flatness is small, and the concrete strength of prefabricated products can reach C40, which is conducive to improving the instability of concrete quality of traditional cast-in-place structures; Secondly, the construction period is controllable. Prefabricated components are produced in factories, and on-site installation is mechanically hoisted, which is safe and convenient, and can also significantly reduce the use of labor. The project duration can be free from the impact of natural weather and other factors; The third is energy conservation and environmental protection. The main body of the project is mostly prefabricated, and a large number of cement, sand and stone and other dust building materials do not need to enter the site. The construction has little impact on the surrounding urban environment. " The prefabricated steel structure building is a form of prefabricated building with high assembly rate, which covers the components of the system such as structure, enclosure, interior decoration and equipment pipeline. It is prefabricated in the factory, and the integrated module is transported to the construction site for assembly and connection to form a complete building. Fabricated steel structure buildings have the advantages of high standardization and high integration, which can greatly reduce the entire construction cycle.

supply Ordinary vertical centrifugal pump Application in water supply and drainage engineering, Ordinary vertical centrifugal pump manufactor Introduction! In recent years, the speed of economic development in China has risen straightly, and GDP is in a steady growth state, which shows that people's living standards are constantly improving. But for the utilization of water resources, people generally have the deep-rooted idea of inexhaustible, which leads to the increasing waste and pollution of water resources. However, at present, the development of urban industrial production has increased the utilization of water resources, so the supply of fresh water resources has presented a shortage problem. In addition, the urban industrial development has aggravated the sewage problem, and the urban sewage problem has gradually become the primary factor threatening the normal development of the city and affecting the urban ecology. Compared with the western developed countries, China's water pollution treatment technology is relatively backward. We must learn from the advanced means and technologies of water pollution treatment in western developed countries, and explore a water pollution treatment road with Chinese characteristics in combination with China's own water pollution treatment status. There may be many problems in the process of exploration, but we must continue to improve and gradually improve the efficiency of water pollution treatment. In many cases, the speed of sewage treatment in China lags far behind the speed of water pollution, while high energy consumption increases the economic load, coupled with the low degree of automation of water pollution equipment, resulting in excessive labor consumption, which will cause difficulties in water pollution treatment in China.
