Description

Technical Field

[0001] The utility model relates to the technical field of plunger pump connection, in particular to a connecting ring for a plunger pump. Background Art

[0002] A plunger pump is a commonly used pressure pump, also called a plunger pump or a plunger pressure pump. It uses plunger movement to generate pressure. It is a fluid conveying device with constant volume and adjustable displacement. The main components of a plunger pump include a plunger, a plunger sleeve, inlet and outlet valves, a piston rod, etc. When the plunger is pushed forward, the volume of the internal cavity will decrease, thereby generating a certain pressure. When the plunger is pulled back, the volume of the internal cavity will increase, thereby sucking in liquid. The movement of the plunger is powered by a driving device (such as an electric motor), and the rotary motion is converted into the linear motion of the plunger through a transmission mechanism such as a connecting rod and a reducer. The plunger pump can provide high pressure and stable flow, which is suitable for industrial needs such as high-pressure spraying, cleaning, lubrication, filling and conveying high-viscosity liquids. It is widely used in chemical, petroleum, pharmaceutical, metallurgical, papermaking and other industries. However, the existing plunger pump connection ring has a simple structure and can only play a sealing role, but cannot stabilize the pipe connection. If the connecting pipe of the connecting ring is moved, the connecting ring will be driven, so that the connecting ring is easily damaged. Therefore, those skilled in the art provide a connecting ring for a plunger pump to solve the problems raised in the above background technology. Utility Model Content
