Working characteristics of gear pump
The working characteristics of gear pumps mainly include the following points:
Suction capacity: When the gear pump is started, it can rely on the rotation of its internal gear to generate negative pressure, thereby sucking in liquid. This feature makes the gear pump have good self-priming ability during liquid transportation, and there is no need to fill the pump with liquid before starting.
Continuous and uniform liquid supply: The gear pump realizes continuous suction and discharge of liquid through the continuous rotation of the gear. Moreover, the higher the speed of the gear pump, the better the uniformity of its liquid supply. This feature gives gear pumps significant advantages in applications where stable flow and pressure are required.
Simple and compact structure: The structure of the gear pump is relatively simple, mainly composed of gears, shafts, pump bodies, pump covers and other components. This simple structure makes the gear pump easy to manufacture, install and maintain. At the same time, the gear pump is also relatively small in size, making it easy to install and use in limited spaces.
Reliable operation: The gears inside the gear pump mesh tightly, allowing the pump to remain stable during operation and reduce vibration and noise. This feature not only extends the service life of the gear pump, but also improves its operational reliability.
Good lubrication performance: When the gear pump is working, the friction between its internal gears will generate heat. In order to reduce friction and wear, gear pumps usually automatically lubricate various components within the pump through the delivered liquid. This feature allows the gear pump to have better performance when delivering lubricating oil.
Wide range of applicable media: Gear pumps are suitable for transporting lubricating oil that does not contain solid particles and fibers, is non-corrosive, has a temperature not higher than a certain range (such as 150°C), and a viscosity within a certain range (such as 5~1500cst) or has properties similar to Lubricants and other liquids. This feature makes gear pumps widely used in petroleum, chemical industry, food, pharmaceutical and other fields.
To sum up, the gear pump has the working characteristics of strong suction capacity, continuous and uniform liquid supply, simple and compact structure, reliable operation, good lubrication performance and wide range of applicable media. These characteristics make gear pumps have broad application prospects in the field of liquid transportation.
