Introduction to maintenance precautions for circular arc gear pumps

Circular arc gear pump; There are three commonly used forms of gears: spur, helical, and herringbone. These three forms each have their own advantages and disadvantages, and have different applications. Straight teeth are a simple form and are preferred for high-pressure applications because they do not have axial thrust and have high conveying efficiency. Material selection is very important in the selection of high-temperature industrial pumps. Gear pumps are commonly used to transport highly corrosive, abrasive, or volatile fluids. The materials of the pump casing, shaft, and bearings must first match the liquid being pumped. When considering high temperatures, the pump becomes more complex and even requires consideration of the thermal expansion properties of different materials. The pulsation of helical teeth is small during the conveying process, and it becomes quieter at higher speeds because the meshing of teeth is gradual.
