Design 1: Double Acting Special Pump
The double-acting special pump is simple and reliable in structure and stable in working performance. The reciprocating double-acting pump realizes to increase displacement, reduce energy consumption and extraction cost through the drainage liquid in the upper and lower strokes.
1. The pump body is connected in series, and the pumping operation is realized in both the upward stroke and the downward stroke to realize double pump displacement;
2. With the structure of ring valve forced open-close of the upper pump, the ball valve is sealed in a timely and reliable manner;
3. The lower pump adopts anti-gas principle of two-stage pump chamber compression to avoid air lock.
