Impeller is mounted within the pump housing 2 slurry pump, and secured on the shaft 3 ZJQ150-30-30 slurry pump, driven directly by the motor shaft. Central pump housing having a fluid suction pipe 4 is connected to a suction 5. Liquid through the bottom valve 6 and the suction tube into the pump. Liquid discharge port on the pump casing 8 is connected with the discharge pipe 9. Before starting centrifugal pumps, pump shell filled with a liquid to be transported; after start, start, the impeller shaft driven by the high-speed rotation ZJQ150-22-22 slurry pumps, liquid between the blades must also be with the rotation. 1. Dive pumping sand pump before starting preparation ① test motor rotation is correct, as viewed from the top of the motor to the pump at the clockwise rotation. Test time is shorter ZJQ200-15-22 slurry pumps, mechanical seals to avoid dry abrasion. ② open the exhaust valve so that the liquid fills the pump, to be filled close the exhaust valve. ③ check all parts are normal. ④ hand drive moving pump lubricating fluid into the mechanical seal face. ⑤ high temperature should be preheated heating rate of 500 degrees per hour, in order to ensure uniform heating ministries.
