Gear Oil Pump Troubleshooting and Elimination Methods
With the development of industrial automation, gear oil pumps are widely used in various industrial fields. In actual work, due to various reasons, gear oil pumps often fail to work normally. This article will analyze and summarize the common faults and troubleshooting and elimination methods of gear oil pumps from the following aspects.
1. Reasons for oil leakage of gear oil pump
The appearance of oil leakage in the gear oil pump may be caused by three reasons: poor assembly seal, poor sealing of the sealing rubber ring, and excessive pressure.
(1) Poor assembly seal: If the seal surface is machined with a large accumulated tolerance and a large deviation, the assembly seal will be damaged.
(2) Poor sealing of the sealing rubber ring: If the sealing rubber ring is damaged or reversed, the sealing of the oil pump will be affected.
(3) Excessive pressure: When the pressure in the pump is too high, the pipe joint is damaged or the sealing rubber ring is worn, and the pipe joint is shaken off, the oil will leak out.
2. Troubleshooting and elimination methods of gear oil pump
(1) Inspect the seal surface and pipe joint of the pump housing: If there is projection or depression in the internal seal surface, the quality of the seal surface should be monitored, the poor quality should be replaced, and the sealing should be redone. Looseness or leakage of pipe joints, it is necessary to adjust or repair the installation correctly. Pay attention to the installation direction of the rubber ring so that it can play a better sealing effect.
(2) Adjust the oil pressure: The pressure should be adjusted in strict accordance with the requirements, and the pressure exceeding the upper limit of the pressure setting range should be reversed in time to avoid damage to the seal.
(3) Adjust the gap between gears: The gap between the gears should be appropriate and adjusted in time to reduce the excessive pressure.
3. Suction filter related problems
(1) Lack of air in the system: When there is no air in the die oil tank, the pump will work without pressure and cannot supply oil. The solution is to check the system, clean the air filter, and check whether the pipeline is installed correctly.
(2) Noise in the system: If there is something blocked in the filter element, this will cause the motor current of the pump to increase. Solution: Regularly clean the filter element or replace the filter element with a new one.
(3) Pollution of the suction filter element: If the filter element is blocked by impurities, it directly affects the working performance of the oil pump. Solution: The filter element should be cleaned or replaced in time.
The above is the fault analysis and troubleshooting and elimination methods of gear oil pumps. Gear oil pumps are very important in industrial production. If you encounter any problems, please contact a professional engineer for maintenance in time to prevent the system from slowing down or stopping production.
