Negative pressure transport principle activated by the pump system of the Sewage Lift Water Tank

When discussing the negative pressure transport principle activated by the pump system of the Sewage Lift Water Tank, we have to have a deep understanding of its key component-the pump, as well as the materials commonly used in these pump systems, especially the application of polyethylene (PE) and linear low-density polyethylene (LLDPE).

Material properties of polyethylene (PE) and linear low-density polyethylene (LLDPE)
As a widely used thermoplastic, polyethylene (PE) plays an important role in many fields with its excellent corrosion resistance, low temperature resistance, good processability and economy. As an advanced form of polyethylene, linear low-density polyethylene (LLDPE) not only inherits many advantages of PE, but also has higher tensile strength, tear strength, environmental stress cracking resistance, low temperature resistance and heat resistance. These characteristics make LLDPE particularly suitable for application scenarios that require high strength, high toughness and long life.

Application of negative pressure transport principle in pump system
In the pump system of 90L Sewage Lift Water Tank, the negative pressure transport principle is to generate a pressure lower than atmospheric pressure in the pump body so that the liquid is sucked in and lifted to the required height or transported over long distances. This principle is particularly important in scenarios such as high-rise buildings, underground parking lots, and remote areas far away from the municipal pipe network, because it can effectively solve the problem that gravity drainage cannot cover.

Material selection and pump system performance
For key components of the pump system, such as the pump body, pipes and seals, the choice of materials is directly related to the operating efficiency and stability of the system. The pump body and pipes made of LLDPE can not only effectively resist the corrosion of sewage, but also maintain good toughness in low temperature environments, reducing the risk of rupture caused by material embrittlement. In addition, the high tear resistance and environmental stress cracking resistance of LLDPE enable the pump system to maintain a longer service life and lower maintenance costs when facing complex and changing working conditions.
