What does plunger mean?

Plunger is a mechanical part, which is usually used in fluid control equipment such as valves and pumps. It consists of a fixed column and a plug that can move in the column. The function of plunger is to control the flow and direction of fluid through the movement of plunger in the column. Plunger is usually made of metal, plastic or rubber, and the specific material depends on its application scenarios and requirements.

Plunger is widely used in fluid control, such as controlling the opening and closing or flow of valves, as well as the pressure and flow of pumps. Among them, plunger valve is a common fluid control device, which uses the movement of plunger in the column to adjust the flow and pressure of fluid. Plunger can also be used for adjustment in production process, such as oil and gas recovery field. Plunger exhaust control valve can be used to adjust gas flow and pressure changes to meet the needs of equipment and systems.

The normal operation of the plunger needs regular maintenance to ensure its stability and reliability. Common maintenance methods include regular cleaning, lubricating oil application and replacement of seals to ensure the normal operation of the plunger and prolong its service life. When selecting the plunger, the appropriate plunger material and specifications should be selected according to the specific scenes and requirements to ensure that various application requirements can be met.
