The gear oil pump is suitable for conveying various lubricating liquids。 Because of this characteristic, the gear oil pump is also called a gear oil pump。 The use of the gear oil pump requires understanding the characteristics of the oil pump。 Therefore, the editor introduces the performance, working principle and application field of gear oil pump。
1。 Performance characteristics
Internal gear oil pump is composed of involute gear or arc gear. Generally with safety valve. The gear oil pump is suitable for conveying lubricating and non-corrosive oil and other liquid media, and is suitable for conveying high-lift media. The gear oil pump is lubricated by the conveyed medium. The advantage is that the medium requirement is not high. The general pressure does not exceed 6MPa. It has the characteristics of self-priming, uniform flow, and reliable operation.
2。 Working principle
The gear oil pump is a volumetric rotary pump. The work is completed by two gears of the same size installed in the housing to mesh with each other and rotate. One driving wheel and one passive wheel. The two ends of the gear are sealed by the front and rear covers. Two independent working chambers are the suction chamber and the discharge chamber. The gears of the oil pump drive the passive gears to rotate during transportation. When the gears are disengaged, the chamber volume gradually increases. A partial vacuum is formed in the suction chamber, and the liquid is sucked in The liquid fills between the teeth of the gear and is brought to the discharge cavity. When the gear enters the mesh, the volume gradually decreases, forming a high-pressure liquid and discharging it out of the pump through the pump discharge port. According to the continuous rotation and meshing of the gears, the liquid is continuously discharged to complete the conveying work.
3。 Scope of use
Gear oil pumps are widely used in petroleum, chemical, marine, power, grain and oil, food, medical, building materials, metallurgy and other industries. Gear oil pump is not suitable for conveying solid particles, fibers and corrosive media. It is suitable for conveying lubricating oil with temperature below 180 ℃ and viscosity between 5 ～ 1500cst or other liquids with similar properties. It is suitable for all kinds of occasions where there is coagulation at normal temperature and outdoor installation work is required in high cold areas. Gear oil pumps are relatively cost-effective.
