Screw pump dosing pipeline “crackling” sound, often become a unique background sound of industrial production site. This sound, although it sounds quite noisy, but contains important information about the operating status of the equipment. In the chemical industry, environmental protection, water treatment and other fields, into the pump industry's screw pumps as the core components of the dosing system, bear the liquid will be accurate, stable delivery to the treatment process of the key tasks. The incessant “crackling” in the pipeline is an indispensable part of this process.
The working principle of the screw pump is through a pair of intermeshing spiral rotor, in the pump cavity to form a continuous sealing chamber, with the rotation of the rotor, these chambers gradually from the suction end to the discharge end, so as to realize the transmission of liquid. During the dosing process, the screw pump and piping system will be affected to different degrees due to the diversity of the nature of the liquid, including viscosity, corrosiveness, solid particle content, and so on.
The “crackling” sound, in most cases, comes from several factors. First, the liquid in the pipeline flow, due to changes in flow rate, pressure fluctuations or media containing gas, the formation of air pockets, the rupture of bubbles and liquid impact noise. Secondly, the gap between the rotor and the pump casing inside the screw pump changes, or the wear of the rotor surface, resulting in mechanical vibration, these vibrations through the pipeline transmission and amplification, the formation of the sound we hear. In addition, the pipe material, the fixing method and the sealing of the connection will also affect the characteristics and size of the sound.
In the face of this sound, can not simply be regarded as a kind of interference and ignored. It is actually an important clue to the maintenance and management of the equipment. Regular detection of changes in the sound, combined with the analysis of the pump's operating parameters (such as flow, pressure, temperature), you can find and deal with potential problems in a timely manner, such as rotor wear, seal failure, pipe clogging, etc., so as to avoid the expansion of the fault, to ensure that the production of continuous and stable operation.
In order to reduce this noise, a series of measures can be taken, such as optimizing the formulation of the liquid to reduce the gas content; selecting screw pumps with low-noise design; strengthening the support and fixation of the pipeline to reduce the vibration transmission; and wrapping the pipeline with sound-proofing materials to reduce the impact of noise on the external environment. Through these means, not only can improve the working environment, but also further enhance the equipment performance, to ensure the accuracy and efficiency of the dosing system.
In short, “crackling” screw pump dosing pipeline sound, although noisy, but also an integral part of industrial production.
