Purpose: Ucting U900-90 is designed to pump chemically neutral hydroxyes with the PH = 6-8 indicator and with a temperature of up to 50 ° C. The maximum size of solid particles in the pumped medium should not exceed 90 mm, the ratio of the solid and liquid phases by mass should correspond to the equality of T: W = 1: 3, the rock content in a solid phase up to 40%, the microstless of the rock of not more than 3000 MN/ m².
Technical characteristics
Uglade U900-90, depending on the frequency of rotation and geometry of the working wheel, have different performance and pressure indicators:
• at 1000 rpm: productivity 600 m 3 /hour, pressure 40 m. Water. Art.
• at 1485 rpm: performance 900 m 3 /hour, pressure 90 m. Water. Art.
• When cutting the working wheel along the shoulder blades by 10%: performance 810 m 3 /hour, pressure 70 m. Water. Art.
The efficiency of the UGLECOSE U900-90 is 71%. The permissible cavitation supply for this coarse should be at least 5.5 meters.
The permitted backfall at the entrance to the Ugles must be no more than 0.9 MPa (90 m).
