Working characteristics of soybean oil vegetable oil gear pump
In the process of conveying soybean oil, vegetable oil and other oils, gear pumps are a common power device, and their working characteristics are mainly reflected in the following aspects:
1. Structural characteristics
Gear pumps are mainly composed of gears, shafts, pump bodies, pump covers, bearing sleeves and other components. These components have undergone rigorous heat treatment and have high hardness and wear resistance, ensuring the stability and durability of gear pumps when conveying high-viscosity liquids such as soybean oil. In addition, all moving parts in the gear oil pump are lubricated by the medium it conveys, reducing the need for additional lubrication.
2. Working principle
The working principle of the gear pump is to convey liquid based on the mutual rolling engagement of gears. When the gears rotate, the spatial volume on the disengaged side of the gears gradually increases, forming a vacuum, thereby sucking in the liquid; while the spatial volume on the meshing side of the gears gradually decreases, squeezing out the liquid and sending it into the pipeline. This process continues as the gears rotate continuously, realizing continuous delivery of the liquid.
3. Working characteristics
Stable flow: The gear pump can ensure the stability of the output flow through the precise meshing of the gears. Even when the working pressure changes, the end face spacing can be automatically adjusted to maintain a stable output flow.
Small pressure pulsation: Due to the optimized design of the internal structure of the gear pump, the pressure pulsation generated during the working process is small, thereby improving the stability and reliability of the conveying liquid.
High volumetric efficiency: The gear pump has a high volumetric efficiency and can make full use of the input energy to convey the liquid. This reduces the energy loss to a certain extent and improves the conveying efficiency.
Good self-priming: The gear pump has a good self-priming ability and can suck the liquid by itself without external drainage. This feature makes the gear pump more convenient during startup and operation.
Insensitive to oil contamination: Due to the particularity of the internal structure of the gear pump, it is insensitive to the degree of oil contamination. Even if there is a certain amount of impurities or particulate matter in the oil, it will not have much impact on the working performance of the gear pump.
However, there are also some potential disadvantages of gear pumps when conveying soybean oil, vegetable oil and other oils. For example, due to the high viscosity of the oil, it may cause the wear of the gear pump to increase, thereby affecting its service life. Therefore, when selecting and using the gear pump, it is necessary to fully consider the characteristics and conveying requirements of the oil to ensure that the gear pump can work normally and perform at its best.
