1, the working principle of arc gear pump:
The arc gear pump is a type of volumetric pump. It consists of two gears, a pump body and a front cover and a back cover. When the gear rotates, the volume of the space on the disengagement side of the gear increases from small to large, forming a vacuum and sucking the liquid. The volume of the space on the meshing side of the gear is reduced from large to large, and the liquid is squeezed into the pipeline. The suction chamber and the discharge chamber are separated by the meshing lines of the two gears. The pressure at the outlet of the gear pump depends entirely on the resistance of the pump outlet.
The circular arc gear pump relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transfer or pressurize the rotary pump. The structure and working principle of the external meshing dual gear pump: A pair of intermeshing gears and cylinders separate the suction chamber from the discharge chamber. When the gear rotates, the inter-tooth space between the teeth on the side of the suction chamber side gradually increases, the pressure decreases, and the liquid enters the teeth under the pressure differential. With the rotation of the gear, the liquid between the teeth is brought to the discharge chamber. At this time, the inter-tooth space between the discharge chamber side gear teeth is gradually reduced, and the liquid is discharged.
2, the application of gear pump:
Suitable for conveying lubricious liquids that do not contain solid particles, are non-corrosive, and have a wide range of viscosities. The flow rate of the pump can reach 300m3/h and the pressure can reach 3x107 pascals. It is commonly used as a hydraulic pump and to deliver various types of oil.
3, the use of gear pump precautions:
Gear pump structure is simple and compact, easy to manufacture, easy to maintain, self-absorption capacity, but the flow, pressure pulsation and noise. The gear pump must be equipped with a safety valve to prevent damage to the pump or prime mover due to a cause, such as a blocked outlet pipe, causing the outlet pressure of the pump to exceed the allowable value.
