Working principle and maintenance of vertical circular arc gear pump

Vertical circular arc gear pump, as a fluid transmission equipment with good speed, is widely used in areas such as petroleum, chemical, metallurgy, and power. Its unique working principle and careful maintenance are key to the long-term stable operation of the equipment. The following is a detailed analysis of the working principle and maintenance of a vertical circular arc gear pump.

1、 Working principle of vertical circular arc gear pump

The working principle of a vertical circular arc gear pump is mainly based on the rotation of gears and the volume change of the enclosed space inside the pump body. When the gears rotate inside the pump body, they together with the pump body and the front and rear end caps form two vertical enclosed spaces - the suction chamber and the discharge chamber.

Inhalation process: When the disengagement side (i.e. non meshing side) of the gear rotates, the volume of the space on that side gradually increases, forming a vacuum or low-pressure area. Under the action of pressure difference, liquid is sucked into the teeth of the gear.

Discharge process: As the gear continues to rotate, the inhaled liquid is carried to the discharge side (i.e. the meshing side). On this side, the inter tooth space of the gear gradually decreases, thereby squeezing out the liquid and forming high-pressure liquid, which is transported to the target position through the pipeline.

Continuous work: Through the continuous rotation of gears, the suction and discharge processes are constantly repeated, thereby achieving continuous transmission of liquids.

The vertical circular arc gear pump adopts a double circular arc sine curve tooth profile, which does not have relative sliding during the gear meshing process, so the tooth surface is not worn, the operation is smooth, there is no trapped liquid phenomenon, the noise is low, the service life is good, and the speed is also good.

2、 Maintenance of vertical circular arc gear pump

In order to ensure the long-term stable operation of the vertical circular arc gear pump, regular maintenance and upkeep are required. Here are some key maintenance measures:

Check and replace seals: Regularly inspect the wear of the pump body, shaft end, and seals. If there is wear or leakage, the sealing components should be replaced with new ones in a timely manner.

Cleaning and lubrication: Regularly clean the pump body and bearings to maintain cleanliness and lubrication. For components that require lubrication, appropriate lubricants should be used to reduce friction and wear.

Check the electrical system: Regularly inspect the electrical circuits, motors, and grounding conditions. Ensure the stability of the electrical system and avoid equipment damage or stability accidents caused by electrical faults.

Adjustment and calibration: Regularly check and adjust the gear clearance, bearing clearance, and sealing degree of the seals. These parameters are within the correct range to improve the pump's operating speed and stability.

Monitoring and recording: Regularly monitor parameters such as pump pressure, flow rate, temperature, and current, and record relevant data. These data help to identify and solve potential problems in a timely manner, and determine the normal operation of the equipment.

Technical training and guidance: Regularly provide technical training to operators to enhance their operational skills and maintenance awareness. At the same time, provide detailed equipment operation manuals and maintenance guides so that operators can use and maintain the equipment correctly and stably.

Regular maintenance and upkeep: Develop a regular maintenance and upkeep plan based on the equipment's usage and the vendor's recommendations. Including cleaning the oil filter, replacing lubricating oil, checking the wear of gears and bearings, etc.

In summary, the working principle of a vertical circular arc gear pump is based on the rotation of gears and the volume change of the enclosed space inside the pump body. For its long-term stable operation, regular maintenance and upkeep are required. By inspecting and replacing seals, cleaning and lubricating, checking the electrical system, adjusting and calibrating, monitoring and recording, providing technical training and guidance, as well as regular maintenance and upkeep, it can be determined that the speed and operation of the vertical circular arc gear pump are good.
