Chemical Raw Materials and Product Transportation

Partnership 
Anhui Shengshi Datang Chemical Equipment Group Co., Ltd. has established long-term partnerships with multiple listed companies, consistently providing technical support to ensure the smooth operation of their production lines. Recently, our technical team overcame significant challenges and successfully secured a cooperation agreement with a major chemical enterprise in Xi'an, Shanxi Province.

Selection

Centrifugal Pumps
As critical equipment for material transportation in chemical production, centrifugal pumps rely on centrifugal force to transfer fluids.

Before startup, it is essential to ensure that the pump body and feed pipe are fully filled with liquid to create a vacuum state. Once activated, the motor drives the impeller to rotate at high speed, causing the liquid to spin rapidly. Under the influence of centrifugal force, the liquid is propelled from the center of the impeller to its outer edge, gaining energy and exiting the impeller at high speed into the volute casing. Inside the volute, as the flow channel gradually expands, the liquid's velocity decreases, converting part of its kinetic energy into static pressure energy. The liquid then exits through the discharge pipe at higher pressure.

During this process, the center of the impeller forms a vacuum as the liquid is expelled, drawing more liquid from the storage tank into the feed pipe under atmospheric pressure or liquid level difference. This enables continuous transportation, akin to water droplets being flung outward when spinning an umbrella rapidly in the rain.

Installation
Proper installation is the foundation for the stable operation of chemical pumps. Our technical team formed a specialized group and traveled to the Xi'an facility to oversee the installation process.

Before installation, a comprehensive inspection of the pump and motor is required to ensure all components are intact, with no looseness or deformation. During installation, it is crucial to maintain the pump's levelness and alignment, as these directly impact its operational stability and service life. Using tools such as spirit levels, the pump's base is adjusted to keep vertical and horizontal deviations within specified limits.

Additionally, the alignment between the pump and motor must be ensured by adjusting the coupling's gap and position to align the centerlines of the two shafts, minimizing vibration and noise caused by misalignment. During installation, attention must also be paid to pipeline connections to prevent leaks and avoid imposing additional stress on the pump body. After installation, a trial run is conducted to check the pump's performance and promptly address any issues.
