large 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 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%.

large Vertical centrifugal pump Function. It is mainly used in the construction of sponge cities such as flood control and drainage, river restoration, black and smelly water treatment, rainwater collection and utilization. Vertical centrifugal pump manufactor It is suitable for living quarters, rural areas, municipal pipe networks, office buildings, shopping malls, streets, hotels, hotels, restaurants, sanatoriums, organs, schools, troops, highways, airports, railways, subway stations, stations, factories, mines, tourist attractions and other domestic sewage and similar slaughtering, paper mills, aquatic product processing Treatment and reuse of organic wastewater from small and medium-sized industries such as food processing plants.

1. To ensure the safety of the pump room, the pump room must be locked. 2、 Vertical centrifugal pump manufactor Safety Operation Regulations, Hygiene and Safety Management System for Secondary Water Supply, Patrol Inspection Specifications, Water Quality Inspection Record System must be posted inside. 3 large Vertical centrifugal pump The following record files must be available inside: Patrol Inspection Record, Water Tank Blowdown Record, Disinfection Record, Water Quality Inspection Record. 4. The pump room must have a pressurized area mark, and the corresponding control system should also have a pressurized area mark: low area, middle area, high area, etc, Mark the product model, qualified number, ex factory date, etc. 6. Water pump identification: the number of pumps must be painted on each pump; For example: 1 # pump, 2 # pump, 3 # pump, 4 # pump, 5 # pump, words. 7. "Normally open" signboard of inlet and outlet valves; 8. The pipe shall be marked with water flow direction arrow; 9. The prefabricated energy-saving pump room needs a drainage system 10. The energy-saving pump room can realize on-site control and remote monitoring;

large Vertical centrifugal pump "Good, fast and economical" Talking about the advantages of prefabricated pump house, 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.

large Vertical centrifugal pump Operation and maintenance of the lifting pump station: 1. The operation management mode of the comprehensive sewage pump station includes the self management of the construction unit, the agent management of the equipment supplier, the centralized entrusted operation, and the self management of farmers. The appropriate mode can be selected according to the specific situation. 2. The design or construction unit of the sewage lift pump station shall train the operation management personnel after the completion acceptance and before the formal delivery of the project, and timely deliver the construction data and system operation management requirements together. 3. The operation and management personnel of the integrated pump station shall be familiar with the operation requirements, technical indicators and safe operation procedures of the treatment process, facilities and equipment, etc., patrol and inspect the operation of the sewage treatment facilities as required, and make operation records in a timely manner. 4. The operation management personnel of the pump station shall regularly maintain, check and clean the relevant equipment to prevent equipment failures and ensure the normal operation of the facilities. five Vertical centrifugal pump manufactor Timely master the water quality of the treatment system to ensure that the water quality meets the standard; If the water quality is not up to the standard, find and solve the problem in time.

large Vertical centrifugal pump What is it? Vertical centrifugal pump manufactor What can I do? We often hear that pump stations have many uses, and are dazzled by various articles. It seems that the more we understand them, the more difficult it is to understand them. Then we will talk about some introductions of pump stations and what they can do. First of all, the pump station looks ordinary to us. Its exterior is dark green glass fiber reinforced plastic cylinder, which seems very simple, but it is not. In fact, the internal structure of the pump station can be very complex and diverse. In the dark green shell of the integrated pump station, there are many parts and components. The core of the pump station we are talking about is the water pump. For pump stations of some sizes, there is not only one water pump, but basically all of them are from the water pump unit. As for the model selection of the pump, the previous articles have also talked about it, so I will not say much here.
