Screw pump It is a new conveying form, which is characterized by simple structure, convenient use, energy saving, good adaptability, and great difference between the operating characteristic curve of the screw pump and the actual operating situation.

Influence of screw pump operation function

According to the operating characteristics of screw pump, its operating function was corrected, and then its operating function was improved, its adaptability was improved, and its service life was extended.

After analyzing the working function of screw pump, a method to improve its working function is proposed, that is, to improve its working function and extend its service life. Field experiments have proved that the use of hollow rotor screw pump can significantly improve the working function of the screw pump, and its compatibility with the process has also been greatly improved. The technical advantages of the use of screw pump with fixed wall thickness are clear, and in the case of poor smoothness, it can effectively reduce the conflict between the rotor and stator, And it can work continuously in some special media.

The flow rate of the screw pump is in a linear relationship with the speed. The flow and head of the high-speed screw pump are higher than those of the low-speed screw pump, but its power has made significant progress. High speed will aggravate the conflict between the rotor and stator, and then lead to the early failure of the screw pump. Moreover, due to the short length of its stator and rotor, simple wear, and then reduce its service life. Speed reduction equipment or stepless speed change equipment shall be selected to control its speed within 300 rpm, and its operation life can be improved several times
