Application principle of vacuum pump

Reciprocating vacuum pump is the application of piston back and forth activities, will transfer energy to the liquid. In order to complete 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 pumps used in practical production are different in construction due to the difference of liquid properties or application targets. When used to transport flammable and explosive liquids, the reciprocating pump driven by steam is often used to ensure safety and reliability.

In order not to damage the piston, a barrier pump should be used when the putrefaction liquid or suspension is carried. That is, an elastic film is used to separate the piston and the body of the food to return to the spring. 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; on the left side of the barrier are filled with water or oil. When the piston moves back and forth, it forces the gap to bend to both sides, resulting in the corrosive liquid or suspension being sucked and pressed out in turn on the right side of the barrier. It does not interfere with the piston. This kind of pump requires huge skill. It is easy to be damaged and difficult to maintain.
