Introduce several troubleshooting methods for gear oil pumps

The main principle of a gear oil pump is that the power nozzle uses the sprayed liquid or gas to drive and accelerate the surrounding liquid, gas, or solid. This movement leads to a mixture of driving and driven substances. The velocity of the jet decreases at the diffusion point while the pressure increases. Unlike traditional pumps, gear pumps do not have moving parts during operation. Gear oil pumps can be made of various materials, such as cast iron, steel, stainless steel, Hastelloy, titanium, enamel, glass, plastic, and graphite, and can be made in various sizes. When the suction capacity ranges from 1 to 200000m3/h and the suction pressure reaches 10-2mbar, the size can range from a few centimeters to over 30 meters. Gear oil pump is a widely used equipment for conveying and compressing mixed gases and vapors, liquids and solids, with gases or liquids often used as power media. Gear pumps are another important application for generating vacuum.
