GPA2-16-E-30-R gear pump is a product suitable for hydraulic systems of various machine tools, such as grinders, balers, injection molding machines, cranes, die-casting machines, and hydraulic stations for artificial board processing and food processing. This article will explain in detail the application of GPA2-16-E-30-R gear pump in grinder hydraulic station.

Basic working principle of GPA2-16-E-30-R gear pump

GPA2-16-E-30-R gear pump is a typical internal meshing gear pump, which consists of a pair of meshing gears. When the active gear drives the passive gear to rotate, the sealed working chamber formed between the gears will change in volume, thereby realizing the suction and discharge of the liquid.

1. 1. Suction stage: When the two gears gradually separate from the meshing state, the gap between the gears gradually increases, forming a local vacuum. At this time, the hydraulic oil in the oil tank is sucked into the tooth valley of the gear and fills the entire working chamber.
2. 2. Discharge stage: As the gear continues to rotate, the hydraulic oil originally sucked in is brought to the meshing point of the gear. When the two gears gradually mesh, the gap between the gears gradually decreases, and the hydraulic oil is squeezed out of the working chamber to form a high-pressure liquid. The high-pressure liquid is transported to other parts of the hydraulic system through the outlet pipe of the pump.

This working principle of the GPA2-16-E-30-R gear pump makes it have the advantages of simple structure, reliable operation, and easy maintenance. At the same time, due to the high meshing accuracy of the gears, the output flow and pressure pulsation of the pump are small, which can meet the requirements of precision processing equipment such as grinders for hydraulic systems.

Application of GPA2-16-E-30-R gear pump in grinder

In grinders, GPA2-16-E-30-R gear pumps are mainly used to provide stable hydraulic power to drive various hydraulic actuators (such as hydraulic cylinders, hydraulic motors, etc.) of grinders. These actuators complete the feeding, grinding, rotation and other processing operations of workpieces driven by hydraulic oil.

1. Grinding feed control: The hydraulic oil output by the GPA2-16-E-30-R gear pump adjusts the grinding feed speed through the control valve group. By changing the opening of the control valve or adjusting the displacement of the pump, the grinding feed speed can be precisely controlled, thereby improving the processing accuracy and surface quality.

2. Grinding wheel frame movement control: During the grinding process, the grinding wheel frame needs to move along a certain trajectory. The GPA2-16-E-30-R gear pump provides stable hydraulic power for the movement of the grinding wheel frame. Through the telescopic movement of the hydraulic cylinder, the grinding wheel frame can move along a predetermined trajectory to ensure the stability and accuracy of the processing process.

3. Workpiece clamping and positioning: Before grinding, the workpiece needs to be clamped and positioned on the grinder. The hydraulic oil output by the GPA2-16-E-30-R gear pump drives the clamping mechanism through the hydraulic cylinder to firmly clamp the workpiece on the grinder. At the same time, by adjusting the positioning mechanism, the position accuracy of the workpiece during the grinding process can be ensured.

4. Cooling and lubrication: A large amount of heat and grinding chips will be generated during the grinding process, and the cooling and lubrication system is needed to reduce the temperature and reduce wear. The GPA2-16-E-30-R gear pump provides the necessary hydraulic power for the cooling and lubrication system. By delivering coolant to the grinding area through the hydraulic pump, the grinding temperature can be effectively reduced, the wear of the grinding wheel by the grinding chips can be reduced, and the grinding efficiency and the service life of the grinding wheel can be improved.

Performance characteristics of the GPA2-16-E-30-R gear pump

The GPA2-16-E-30-R gear pump has a variety of performance characteristics, making it suitable for precision processing equipment such as grinders.

1. High pressure stability: The GPA2-16-E-30-R gear pump has a high working pressure and a stable output flow, which can meet the requirements of the hydraulic system of high-precision processing equipment such as grinders.

2. Low noise: Due to the high meshing accuracy of the gears, the GPA2-16-E-30-R gear pump generates low noise during operation and will not interfere with the working environment.

3. Strong self-priming ability: The GPA2-16-E-30-R gear pump has strong self-priming ability and can suck hydraulic oil from the oil tank without external auxiliary equipment.

4. Easy maintenance: The GPA2-16-E-30-R gear pump has a simple structure and is easy to disassemble and assemble. During maintenance, it is convenient to check the wear of the gears, replace seals, etc.

Maintenance of GPA2-16-E-30-R gear pump

In order to ensure the normal operation and long-term use of the GPA2-16-E-30-R gear pump on the grinder, regular maintenance work is required.

1. Regular inspection: Regularly inspect the GPA2-16-E-30-R gear pump, including checking the wear of the gears, the lubrication of the bearings, the integrity of the seals, etc.

2. Cleaning and maintenance: Keep the GPA2-16-E-30-R gear pump and its surroundings clean, and regularly clean the oil tank and filter to remove impurities and dirt in the hydraulic oil. At the same time, lubricate and maintain the various parts of the pump to extend its service life.

3. Replace the hydraulic oil: According to the use of the hydraulic oil and the processing requirements of the grinder, replace the hydraulic oil regularly. When replacing the hydraulic oil, ensure that the cleanliness and quality of the new oil meet the requirements.

4. Troubleshooting: When the GPA2-16-E-30-R gear pump fails, it should be stopped in time for inspection and troubleshooting. During the maintenance process, the relevant safety operating procedures and maintenance specifications should be followed to ensure the quality of maintenance and personnel safety.
