large Integrated sewage 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 Integrated sewage 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%.

1. To ensure the safety of the pump room, the pump room must be locked. 2、 Integrated sewage pump set 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 Integrated sewage pump set There must be the following record documents inside: Patrol Inspection Record, Water Tank Blowdown Record, Disinfection Record, Water Quality Inspection Record. 4. The pump room must be marked with the pressurized area, and the corresponding control system should also be marked with the pressurized area: 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 Integrated sewage pump set It is an important water conservancy equipment in urban infrastructure construction, Integrated sewage pump set manufactor It is mainly used for municipal drainage, flood control and waterlogging drainage in flood season, and can be divided into sewage lift pump station and rainwater lift pump station according to the action objects. It is generally installed underground and connected with the urban underground sewage pipe network to collect domestic sewage and rainwater. It is a new environment-friendly pump station. After the mixing treatment, the water level is raised by pressurizing the water pump, and the sewage is transported to the sewage treatment plant, realizing the rapid discharge and treatment of urban sewage.

large Integrated sewage pump set Explain the structure of the integrated prefabricated pump station: 1. Outdoor stainless steel control cabinet: manual and automatic. The following control functions can be realized: (1) Daily automatic position, realizing unattended pump station. (2) Two for use and one for standby, mutual standby, automatic switching, high water level working at the same time, automatic fault switching. 2. Crushing grid: the crushing grid is placed at the inlet of the FRP cylinder of the pump station, and the submersible crushing grid is safe and reliable; The supporting guide rail is convenient for maintenance and overhaul. 3. Liquid level sensor: pressure sensor (standard configuration)/floating ball switch/water level electrode is used, and special monitoring relay is provided to realize automatic control operation of pump station liquid level. four Integrated sewage pump set manufactor Service platform: built-in service platform for valve and water pump maintenance; Customize platforms in different forms, locations and heights as required.

large Integrated sewage pump set How to choose? Integrated sewage pump set manufactor The main equipment in the pump station selected according to the input and output are: various controllable valves, pump sets, grid systems, water level gauges, flow meters, etc. According to the requirements of the system and the different control methods adopted, as well as the nature, parameters and characteristics of the input and output signals, the appropriate PLC system can be flexibly selected. Select according to the storage capacity Calculate the actual capacity demand of the storage according to the number of nodes required for programming. The PLC control system used in the current pump station is selected according to the communication requirements, which is generally divided into equipment unit layer, pump station layer, dispatching layer, etc. Layers directly need to transmit various parameter information, so we should select the appropriate PLC equipment according to the field needs, such as network, expansion, off the shelf bus connection, investment and our own equipment.
