Branch machinery small series again to share dry goods, today: single screw pump selection skills. Single screw pump is also widely used, its model how to choose, quickly come to see it

Selection skills of single screw pump:

The specification of single screw pump is determined by the nature, flow and pressure of the liquid to be transported, and the speed of the pump is chosen by the viscosity and corrosiveness of the conveying fluid as the main parameter, so as to ensure the reliable operation of the pump

Design speed of single screw pump for conveying non corrosive liquid water or water net similar to the highest speed, in actual use because of the requirements of nature and life in different medium, selection generally should be less than the design speed. The high viscosity and medium containing particles, the general design speed of 1/2-1/3 or lower, low speed is favorable to the wear of the pump, but after use due to wear of the stator flow decreased, then the appropriate progress speed, to compensate for decreased flow often policy.

The medium temperature should be -10 to 80 DEG C for special cases can be as high as 120 degrees Celsius. Each pump (a stator lead) and normal pressure 0.6Mpa, a short period of time (no more than 30 minutes) in the promise of up to 0.8Mpa, when worn in the same volumetric efficiency of the output pressure should be gradually decreased pumping water. When the maximum suction is 8 meters, the actual use of recommended no more than 6.5 meters, when pumping high viscosity medium, with positive pressure breathing.

The above is the branch of small machinery according to the actual work of the sorting out, hope to help you to choose the right screw pump. If there are other problems, you can call the website official website, telephone consultation oh
