The design principle of the integrated sewage prefabricated pumping station

2019-10-30
The development of any pump is based on the science. Especially with the advancement of technology, the pump industry has developed rapidly and an integrated prefabricated pumping station has emerged. So, how is the integrated prefabricated pumping station design and development? What is the design principle?

The overall design principle of the integrated sewage prefabricated pumping station:

The liquid level information of the pump station is fed back to the control system by the pressure sensor or the float ball, and then the water pump switch is operated by the operating parameters set by the control system. When the liquid level reaches the liquid level of the pump set by the system, the control system will control the pump to start, so that the sewage will be pumped from the pump station to the exit of the municipal sewage pipeline; when the sewage pumping is lower than the system setting liquid level, the system will control the pump to stop pumping. This process will repeat, so that the integrated sewage prefabrication pump station runs smoothly.

First, the antislip cover design of the integrated sewage prefabricated pump station
The antislip top cover material is made of GRP. The inner and outer surfaces of the cover plate are flat, and cracks with a depth of 2mm or more are not allowed. Layered delamination is not allowed, and the fibers are exposed, the foreign matter are mixed, and the uneven color. It can effectively prevent aging for a long time exposed to sunlight. The overall top cover has antislip measures, such as antislip patterns or granules, and is printed with anti-corrosive paint.


 
Second, the cylinder design of the integrated sewage prefabricated pumping station
The glass fiber reinforced plastic cylinder body is made of alkali-free glass fiber roving and its products as reinforcing materials, and the thermosetting resin is high-grade resin. The computer controlled winding process is used to ensure uniform thickness and meet design requirements. The thickness of the structural layer is determined by the structural design. The pumping station structure of the integrated prefabricated pumping station of Better Technology Co., Ltd. is made of GRP. It is equipped with Italian (VEM) equipment and fully automatic control of continuous winding type to ensure uniform thickness and reach design rigidity. The quality is stable and excellent.

Three. the Design of stains flow of the integrated sewage prefabricated pumping station
The CFO flow field calculation is used to discharge solid particles such as sludge as much as possible out of the equipment. In addition, because the conveying medium contains a large amount of sand, oils and fats, and various living impurities, especially the high concentration of chlorine ions in the sewage, according to the special requirements, the cutting blade material of the pulverizing grid machine has high strength and hardness conditions. Corrosion resistance is also required. The pulverized grid should be able to run continuously for 24 hours a day, ensuring that the solid particle size after cutting should be above 15-16mm, and the granules should not be shredded by less than 10mm to prevent solid particles from passing directly through the lifting grid of the sewage treatment plant.

Four, the design of the drive shaft of the integrated sewage prefabricated pump station
The surface hardness of the drive shaft should be above 60HRC, and the tensile tension should not be less than 1,027kPa; it is resistant to mud and sand wear. The bearing is protected by a bearing sleeve consisting of a replaceable crankshaft unit and a mechanical seal. The service life of the bearing should not be less than 100,000 hours.
Five. the design of service platform for integrated sewage prefabricated pumping station
The pump is self-coupled with a vertical wet installation. The pump and inlet wells are integrated into the same wellbore with an internal service platform and ground control panel.
The above is the main design principle of the integrated prefabricated pump station.
