    What is a detachable dowel joint?

    The detachable joint depends on the reciprocating piston (or plunger) in the detachable joint cylinder to change the volume of the detachable joint cylinder, with the action of two check valves, to achieve the purpose of suction or discharge of liquid. According to the structure of the piston, it can be divided into three kinds: piston detachable joint, plug detachable joint and diaphragm detachable joint. The main component of the piston detachable joint is the piston, relying on the piston to work in the removable joint cylinder, inhaling or excreted liquid. The main part of the plunger detachable joint is the plunger (cylindrical), which is larger than the piston contact area and wear-resistant. The detachable joint acts in exactly the same way as the piston.
