A piston pump is a mechanical device capable of compressing and transporting liquids or gases. It consists of a piston, cylinder, inlet and outlet valves, and seals. The piston pump compresses substances using the piston and transfers them into the cylinder, then outputs them through the outlet valve. The flow rate at the outlet can be adjusted by changing the state of the inlet and outlet valves and the frequency of the piston's movement.
The working principle of a piston pump is simple, and its operation can be divided into four steps: suction, compression, discharge, and return. As the piston moves, the inlet valve opens to draw the substance into the cylinder, then closes the inlet valve and opens the outlet valve to allow the piston to move downward and compress the substance. After compression, the piston stops moving, the outlet valve closes, and the inlet valve is opened to prepare for further operation.
