Reciprocating vacuum pump is the use of piston back and forth movement, the energy is transmitted to the liquid. To end the mission of liquid delivery. The flow rate of reciprocating pump is only related to the displacement of piston and the condition of pipeline, but the lift of reciprocating pump is only related to the condition of pipeline.
The reciprocating pump used in practical production has different structural methods because of different liquid properties or different application targets. When used to transport flammable and explosive liquids, the reciprocating pump driven by steam is often used for safety.
In order to prevent piston from being damaged, a barrier pump is used to separate the piston from the main body by using an elastic film. This elastic film is made of rubbers or special metals with good abrasion resistance and corrosion resistance. All parts on the right side of the barrier are made of or lined with anti-corrosion materials; the left side of the barrier is filled with water or oil. When the piston moves back and forth, the gap is forced to turn to both sides alternately, resulting in the corrosive liquid or suspension being sucked and pressed out in turn on the right side of the barrier. Not with the piston. This kind of pump requires huge skill. It is easy to damage and difficult to repair.
