Problems solved by technology

[0003] 1. For S-pipe valve delivery pumps, C-shaped pipe valve delivery pumps, and skirt valve delivery pumps, material backflow will occur during the reversing process of the two-cylinder pumping, thereby reducing the delivery efficiency. The longer the delivery distance, the higher the delivery height. The higher the pressure, the greater the conveying pressure, the more serious the material backflow, and the lower the conveying efficiency
[0004] 2. For the gate valve delivery pump, due to the poor sealing performance of the gate valve and no wear compensation mechanism, the pumping pressure is low, the delivery distance is short, and the delivery height is low
[0005] 3. For the above-mentioned various types of delivery pumps, since there is only one suction port, when transporting materials with poor fluidity, the material flow resistance is large and suction is difficult, resulting in low volumetric efficiency
