Integrated underground prefabricated sewage lifting pump station

With the development of China's economy, land has now become a constraint factor for China's economic development. Now the utilization rate of underground construction space is getting higher and higher, such as: underground shopping malls, subways, underground parking lots, basement of Biry district, etc. The original underground sewage storage and discharge facilities not only have outdated technology, high failure rate, and difficult maintenance. They are also regularly cleaned. The odors emitted by sewage and sewage seriously pollute the surrounding environment. The injuries caused by maintenance personnel also occur from time to time. Therefore, the original facilities can no longer meet the requirements of modern life and business activities. On the basis of the original SHWS (F) series integrated sewage lifting device, our company has launched a new generation of large-scale prefabricated pumping stations to make up for the intestinal problems of sewage delivery after SHWS (F) parallel connection. The prefabricated pumping station follows the advantages of the original sewage lifting device "filtering" and "backwashing", and at the same time realizes the sewage lifting and discharging function. The promotion of the SHWS (YZ) series of pre-created pumping stations. In addition to effectively satisfying the function of sewage transportation. In the selection of transportation equipment, we should focus on how to avoid clogging of the equipment, clean up, and how to remotely prevent the emission of odor and odor. The surrounding environment; in addition, the biggest feature is the saving of investment, the small area, the project period is greatly shortened, the appearance is beautiful and neat: fully automatic operation, can realize fault alarm, remote monitoring function. The operation is more safe and reliable:

SHWS (YZ) series prefabricated pumping stations are used to collect and discharge sewage and wastewater in residential quarters, schools, military barracks and other public places. They are mainly installed outdoors and underground, and are also used indoors. There are many options for the diameter of the cylinder (φ1200, φ1600, φ2000, φ3000, φ3800), the flow range is 25US3-1350USo and the multi-cylinder scheme can be used when it is larger.

The power supply frequency is 50Hz, the three-phase alternating current is 380V, and the debris (including flexible debris and solid particles) in the sewage must be able to flow by itself in the pipeline. Sewage temperature does not exceed 40 ℃, PH value is 4-10, the improvement of ordinary domestic sewage and wastewater. For new buildings, construction waste must be removed from the sewage pipeline before use. For oily sewage in restaurants and kitchens and hair water in baths, it must be treated with oil and hair removal before use.

1. Very little land occupation: The prefabricated pumping station is buried underground and integrated with the surrounding environment. There is no civil construction of the pumping station on the ground and no land occupation index. The buried structure makes it beautiful and elegant, and the environment is beautiful.

2. Integrated products: Whether you require dry or wet pump pits or a combination of the two, we can accurately prefabricate such pumping stations. The pumping station is transported as a billetized unit, including the barrel system, water pump system, grid system, piping system, valve system, control system and other components.

3. Solid and durable: The equipment cylinder is made of alkali-free glass fiber reinforced plastic, and is combined with 901 resin winding. Its strength is equivalent to twice that of traditional laminated glass fiber reinforced plastic. The circumferential tensile strength is greater than 300Mpa, and the axial tension The strength is greater than 80Mpa, and the compression strength is greater than 200Mpa, which can completely resist corrosion, tearing and other destructive forces, and ensure permanent waterproof and durable.

4. Short construction period: The prefabricated pumping station is supplied as a complete set. The assembly and testing of each system are completed in the factory. The time required for installation and commissioning after delivery to the site is greatly reduced. In addition, the workload of civil engineering is only 1/10 of the traditional pumping station, which greatly shortens the construction period of the whole project.

5. High efficiency, environmental protection and cost saving: The prefabricated pumping station uses CFD flow field analysis to ensure that the system is in high efficiency. Operation, plus a dedicated automatic control system to ensure that the pump can automatically adjust according to system requirements, ensure automatic and efficient operation to save operating costs. In addition, compared with the traditional pump station structure, the investment in the pump station saves nearly 25%. And it covers a small area.

6. Fully automatic control: A float switch (standard) input type liquid level transmitter or an ultrasonic liquid level gauge and other sensors are used to detect the liquid level, and the start and stop of the water pump are automatically controlled. Overload, short circuit and other protection functions are complete, which can effectively reduce the damage rate of the equipment. Other optional functions can be added according to customer needs. For example: equipped with a full Chinese man-machine interface. Dynamic display of the operating status and funding information of each device; establishment of wireless Wifi signal reception, monitoring of the device with mobile terminals (mobile phones or tablets) Operation, failure and other states (when controlled by mobile terminal. It must be equipped with a man-machine interface); use remote monitoring software to remotely monitor the operating state of the device from the computer and collect and manage the data.

7. Convenient installation and maintenance: the prefabricated pumping station is installed as a whole; the equipment in the pumping station, such as pumps and grids, need not be entered into the simplified version for maintenance. It is directly hung from the top and hanged out; the internal piping system is provided with an inspection platform in the pumping station And climbing stairs.

8. Long service life: the inner wall of the cylinder is smooth, long-term use does not hang dirty, no maintenance, water pump system, grid system, pipeline system are made of anti-corrosion materials. Long service life.

5. Finite element analysis: finite element analysis of the cylinder, analyze the stress and strain analysis of the cylinder under 30 years of soil pressure, and guide the production of the cylinder under this report: CFD flow field analysis on the cylinder The hydraulic analysis is carried out inside the body to analyze the velocity distribution, pressure distribution and flow field distribution of the water flow in the flow field, and the shape of the pump and the bottom pit at the bottom of the barrel are reasonably arranged. Increase the vortex generated during the pumping process, make the bottom of the pit have a self-cleaning function, prevent the silt from accumulating at the bottom of the pit, and effectively suppress the generation of toxic and malodorous gases. Protect the environment.

6. Pump patrol inspection and self-cleaning control module: a patrol control module can be installed in the control cabinet. When the pump is not running for a long time, the pump can be started to run for a short time to ensure the normal operation of the submersible pump. Through this module, the water pump can bypass the main control system and run directly to lower the liquid level until the water pump cannot suck in sewage. The controlled turbulence generated by the water pump sucks the particles deposited on the bottom together with scum into the pump and discharges it. The frequency of this action is adjustable
