The relationship between the flow rate of gear pump and speed
Gear pump is suitable for conveying containing no solid particles and fibers, non-corrosive, temperature is not higher than 150 ℃, the viscosity of 5 to 1500 CST lubricating oil or other liquid properties similar to lubricating oil. Try all kinds of outdoor installation and process of outdoor installation and process in high - cold area under normal temperature.
The gear oil pump is a volumetric pump, and its structure consists of a pair of meshing gears and pump shells. The pump is the same amount of output per revolution. With the constant rotation of the driving shaft, the pump also pumps out the fluid continuously. The flow of the pump is directly related to the pump speed.
Have to rise to get big flow pump rotation speed, for a pump rotation speed, is actually limited, which mainly depends on process flow, if transfer is oil, pump can at high rotation speed, but when the fluid is a kind of high viscosity polymer melt, the restrictions could be greatly reduced.
Gear oil pump and self-priming centrifugal pump working principle of the big difference is that both are different, although both are as part of the oil pump, but the centrifugal pump is mainly used in oil facilities, hydraulic facilities, etc., and the gear pump used in all walks of life, has a wide range.
Characteristics of centrifugal pump
Used to transport petroleum products such as gasoline, kerosene, diesel and aviation kerosene. Medium temperature in - 20 ℃ ~ + 80 ℃, it is a good ship loading and unloading of oil pump. It is suitable for oil conveying of oil storage equipment such as land oil depot and oil tanker. It can also be used to transport seawater and fresh water.
The characteristics of the gear pump
1. Compact, easy to use and easy to maintain.
2. Good self-absorption, so it is not required to fill the liquid before each pump.
3. The lubrication of gears is automatically achieved by means of conveying liquid, so it is unnecessary to add lubricating oil to the daily work.
It is widely used in oil, chemical, ship, electric power, grain and oil, food, medical, building materials, metallurgy and defense research and other industries.
