BOS self-priming rotary displacement pump

1, the rotor is a pair of conjugate cams, when the cam is rotated, the suction port of the vacuum, the liquid fills the pump chamber. Cam continues to rotate, the liquid sent to the discharge outlet closed, no suction and discharge valves. 2. Domestic named rotary piston pump, cam rotor pump named foreign or rotary cam pump. 3. Comparison with the screw ① ② energy-saving one-third of the maintenance period over screw. ③ online maintenance, replacement parts without having to remove any pipe, quick implementation. ④ Nonextruding works, fewer components requiring maintenance, saving cost of spare parts. When ⑤ can dry run, suddenly breaking material or operational errors, it is especially important to avoid accidents. ⑥ installation volume is a third of the screw pump. 4, and the centrifugal pump can compare ① material is not blocked by the large size. ② without cavitation. ③ to achieve gas, liquid and solid mixed transport. 1, high efficiency 75-85% 2, high self-priming 1-9m 3, high-lift 1-200m flow 0.5-1400 4, high viscosity 02-10Pas 5, no plug, no bottom valve, resistant to dry grinding, heat 6 , corrosion - for media containing various chemical ingredients 7, while conveying the gas and liquid can be reversing. 8, online quick repairs without dismantling the pipes and wires. Suitable for sludge treatment, sewage, oil depots sweep warehouse unloading tankers, three-phase vapor-liquid-solid crude oil, paraffin, suspensions, gasoline, diesel fuel, lubricants, paints, toothpaste, crude oil, heavy oil, coal tar, pitch, transport oil, all kinds of pulp, resins, solvents, fibrous material.
