Gear pump is formed by rely on the pump cylinder and the meshing gear working volume change and move to transport the liquid or causes the pressurization of the rotary pump. By two gears, pump body and cover of two closed space, when gears rotate, gear side space volume from small greaten, forming a vacuum, the liquid suction, the side of the gear mesh volume from large to small of the space, and the liquid in pipe line. Suction chamber and discharge chamber is separated by two gears meshing line. The gear pump outlet pressure depends on the size of the source resistance pump.

1. High efficiency, precise and detailed structure design, this series pump with high volumetric efficiency and high mechanical efficiency.

2. High reliability, light weight, tight and fine.

3. Advanced casting nature, to ensure stable and reliable performance.

4. The big flow of vane pump with low pressure high and low pump combination, reasonable use of primary energy and cost savings.

Note: 
1. Should be used with anti-foam, prevent oxidation and anti-corrosion additive such as mineral oil, oil of aniline point of 77-77 degrees

2. The recommended oil temperature: 10 to 60 degrees, the temperature limits, and 20 to 80 degrees

3. Recommend a suitable viscosity: 15-150 CST (15-150 was a/s), boundaries using viscosity: 10-430 CST (10-430 mm2/s)

4. Oil suction mouth pressure: -0.02-0.03 MPA (- 02-0.3 KGF/cm2), bottom temperature instant start Mpa (0.4 kgf/cm2)

Gear pump working principle

When the driving gear of the gear pump rotates, the gear of the oil suction chamber disengages and meshes, the gear teeth of the gear exit between the teeth, increasing the sealing volume and forming a local vacuum. Under the action of external atmospheric pressure, the oil in the oil tank enters between the teeth through the oil suction pipeline and the oil suction chamber. As the gear rotates, the oil between the suction teeth is carried to the other side and into the oil chamber. This is the gear into mesh, so that the seal gradually reduced, part of the oil between the gear is extruded, forming the gear oil pressure process. When the gear meshes, the contact line of tooth direction separates the oil suction chamber from the oil pressure chamber and plays the role of oil distribution. When the driving gear of the gear pump is driven by a motor to continuously rotate, the gear is detached from the meshing side. As the sealing volume increases, oil is continuously sucked from the oil tank and the gear tooth enters the meshing side. As the sealing volume decreases, oil is continuously discharged, forming a continuous cycle process

What is the main difference between centrifugal pump and gear pump

Gear pump is a positive displacement rotary pump. The working principle is that one driving gear in a pair of meshing gears rotates by the motor, and the other driven gear rotates by meshing with the producing gear. When the two teeth are gradually separated, the volume of the working space is gradually increased, forming a partial vacuum. Under the action of atmospheric pressure, liquid is inhaled through the suction tube. The suction fluid is extruded along the inner wall of the pump by the gears.

 

The main part of centrifugal pump is pump shell and impeller inside the shell, impeller shaft and motor connected. Before starting the pump, it is necessary to fill the pump shell with water to discharge the air in the shell. After starting, the impeller is driven by the motor to rotate at high speed, and the water in the pump shell also rotates at high speed with the impeller. In this way, due to the inertia of water is thrown into the water pipe, the pressure around the impeller greatly reduced, atmospheric pressure will be low water pressure, open the bottom valve into the pump shell. And so on, you can keep pumping water up and throwing it up.

 

Centrifugal pump work its inlet valve must first open, and has been open.

Difference: gear pump is generally used as a metering pump, its treatment is small, but high head. Dosage is easy to control. Centrifugal pump is generally used to transport a large number of liquid, its characteristics are: large output.
