In essence, a screw pump is a kind of positive displacement pump. This type of screw pump with wide-ranging applications is often used in chemical, petroleum, shipbuilding and other industries. The internal gear's rotation allows the transmission medium to be continually transferred to the discharge end during the application operation. Meanwhile, the progressive cavity pumps are highly efficient in achieving a constant volume and uniform speed of media transfer during operation. This article shows the introduction and analysis of the range of applications of screw pumps.
Compared with other pumps, screw pumps have the advantages of small size, low noise and varied transporting capabilities. In addition, the machines have a high self-priming capability and can transfer a volume of liquid with tiny particles. Therefore, you can choose the screw pump type to improve your working efficiency according to the demands of the task and the transportation way.
Screw pumps are made up of two main parts, the teeth of the pump screw and several sealing chambers formed by the pump sleeve. Media transmission is realized by the recurring attraction between these two components. The screw pumps not only have a relatively balanced flow rate, but also have features of long service life, reliable operation and excellent efficiency. In addition, screw pumps with wide applications can transport solids, liquids and gases in any direction. Therefore, the machine is often used in the petrochemical and marine engineering industries.
The screw pump is suitable for conveying a wide range of media types, primarily for various screw pump kinds. The kinds of screw pump can determine the transmission of media. There are many kinds of screw pumps, including single screw pumps, double screw pumps and triple screw pumps. As a result, you had better choose the suitable type of screw pump based on the needs of the project and the actual transmission medium. Single Screw Pump
The single screw pump's primary function during operation is to move the medium containing metal particles to the discharge end. Between the metal screw and the metal screw, there are several sealing chambers and the metal screw's primary function during operation is eccentric rotation. During the movement, the liquid is suctioned and discharged as the low-pressure area is moved to the high-pressure area. The single screw pump allows to mainly convey the medium containing metal particles to the discharge end, it is more common to process slurry and sewage. Double Screw Pump
The entire column cavity's screws of the double screw pump mesh to create multiple sealed cavity constructions. If the spiral life angle is large, the auxiliary screw can be driven. Consequently, the twin screw pumps are mostly used in the petrochemical industry by the machine can efficiently move mida with high viscosities. Triple Screw Pump
The three-screw pump is a typical screw pump, its working way is using one main screw to drive each of the two sub-screws. Every screw has two tow screw lines in it, meanwhile, the sealed cavity is created during the procedure. It should be mentioned that the medium must not be corrosive or viscous as it is primarily used to carry oil and other media. Incidentally, you would do well to take note of the amount of media and the percentage that needs to be conveyed.
