Slurry pump structure determines efficiency
Enterprises pay more attention to their efficiency when using slurry pumps, and high-efficiency slurry pumps are directly proportional to the structure. Below we explain from several aspects, what kind of structure can ensure the efficient operation of the slurry pump.
First, the maximum lift of the rubber impeller should not exceed 63m. The maximum allowable line speed should not exceed 30m/m; the slurry pump bearings are generally selected from rolling bearings and are lubricated with thin oil or grease, and their working temperature should not exceed 75 degrees;
The pump's transmission can be equipped with a flexible coupling, a drive belt or a fluid coupling. Couplings, V-belts and pulleys shall have safety shields;
Secondly, for the double-shell pump of the rubber inner shell, the maximum size of the solid particles in the slurry should not exceed 3 mm, and there is no sharp edge;
For single-shell pumps and double-shell pumps with metal inner casing, the maximum size of solid particles in the slurry should not exceed 80% of the minimum size of the flow section; the packing sealing water pressure should be higher than the pump discharge pressure of 35 kPa.
