supply Fire fighting integrated pump set 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 Fire fighting integrated pump set 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%.

supply Fire fighting integrated pump set While making outstanding contributions to sewage collection and treatment and flood control and waterlogging drainage, it also has many defects, such as large floor area, high cost, and easy to produce methane volatilization to pollute the environment. But with the upgrading of technology, Fire fighting integrated pump set manufactor According to the market demand, we have developed and produced an integrated prefabricated pump station with more optimized performance, which has solved many disadvantages of the concrete pump station and replaced the traditional concrete pump station as the current mainstream pump station.

supply Fire fighting integrated pump set Noise includes pump noise, motor noise and pipeline noise. There is no staff in the assembled pump room during the normal operation of the pump, so the main purpose is to protect the residents around the pump room from being affected. The pump house is mostly used in the basement of residential buildings, Fire fighting integrated pump set manufactor During operation, the vibration noise of the pump unit spreads along the floor and wall to the upstairs, resulting in obvious vibration of the wall, floor, ceiling and column head of the owner's room upstairs. The room buzz has a serious impact on the human body. Many cities in the north need heating in winter, so many communities have set up heating pump rooms. Ventilation and heat dissipation are required in the pump room, and sound leakage is serious when the pump is running. There will be a high noise sound pressure level outside the pump room, which will seriously affect the quality of life and sleep of residents in the community.

Fire fighting integrated pump set manufactor The integrated prefabricated pump station is a comprehensive urban drainage and water supply device that provides potential energy and pressure energy for water. It is composed of cylinders, pipelines, electromechanical equipment, electrical control and other ancillary facilities, and is scientifically matched, reasonably designed and assembled. Its drainage performance, safety performance and operation reliability directly determine the safety of urban drainage and water supply. supply Fire fighting integrated pump set The demander's requirements for its performance are also getting higher and higher, so detection is the way to obtain the demander's approval.
