The working principle of a plunger pump is to change the volume of the sealed working chamber through the reciprocating motion of the plunger in the cylinder body, thereby achieving the functions of oil suction and pressure. A plunger pump relies on a sealed working chamber formed between the plunger and the cylinder bore. The plunger undergoes reciprocating movements of extension and retraction in the cylinder bore, causing the volume of the chamber to periodically change. At the same time, the suction and discharge ports of the plunger pump are reliably separated, ensuring the normal operation of the pump. ‌ The structure of a plunger pump mainly includes two parts: …

The working principle of gear pump is relatively intuitive and efficient. It is a positive displacement pump designed and manufactured using the principle of gear meshing. The following is a detailed explanation of its working principle: 1. Basic Structure Gear pumps are mainly composed of two or three gears, pump casing, electric motor, and seals. Among them, two gears (the driving gear and the driven gear) are tightly matched inside the pump casing, forming a closed volume space. 2. Working Process Inhalation stage: When the gear rotates under the drive of the motor, the meshing teeth on one side of the suction chamber gradually separate, causing the volume of the …
