Will the pressure value of the gear oil pump also fail to increase?

Analysis of the problem of the pressure value of the gear oil pump not increasing

Gear oil pump is a commonly used fluid conveying equipment in industrial areas, which uses a pair of meshing gears to pump liquids. However, during use, sometimes there may be issues with the pressure value of the gear oil pump not increasing, which can have a serious impact on production rate and equipment performance. The following is a detailed analysis of this issue, including possible causes, impacts, and corresponding solutions.

1、 Possible reasons

Internal wear of oil pump

After prolonged use of the gear oil pump, components such as gears and bearings may experience wear, leading to increased clearance and internal leakage. This will reduce the output pressure of the oil pump and prevent it from reaching the expected pressure value.

Oil suction pipeline problem

Blockage, poor oil suction, or poor sealing of the suction pipeline can all cause the oil pump to be unable to suck in enough liquid, thereby affecting the output pressure. In addition, if the oil temperature is too low or the oil level is too low, it may also cause the oil pump to have difficulty absorbing oil.

Oil pump drive device malfunction

Malfunction of the driving device of the oil pump (such as motor, belt, etc.) may result in the oil pump being unable to obtain sufficient power to generate the required pressure. For example, belt looseness or breakage can cause a decrease in oil pump speed, thereby affecting output pressure.

Oil problem

The viscosity of the oil, whether too high or too low, may affect the performance of the oil pump. Excessive viscosity can increase the resistance of the oil pump, while low viscosity may lead to increased internal leakage of the oil pump, both of which are not conducive to the establishment of pressure.

Improper installation of oil pump

If the installation position and angle of the oil pump are incorrect, it may cause poor oil suction or obstructed oil discharge, thereby affecting the output pressure. In addition, if the inlet and outlet valves of the oil pump are not opened correctly or have faults, it may also cause the pressure to fail to rise.

other factors

If the one-way valve gets stuck, the seal is poor, the oil pump parts are severely worn, or the oil suction filter screen is blocked, it may also cause the pressure value of the gear oil pump to not increase.

2、 Impact

The failure to increase the pressure value of the gear oil pump will directly affect the normal operation and production rate of the equipment. For example, in hydraulic systems, if the output pressure of the oil pump is insufficient, it may cause the system to malfunction or even lead to malfunctions. In addition, long-term operation under low pressure may accelerate the wear and tear of the oil pump and system, shortening the service life of the equipment.

3、 Solution measures

Check and replace worn parts

Regularly check the wear of the oil pump and replace severely worn components such as gears and bearings in a timely manner to reduce the impact of internal leakage and increased clearance on output pressure.

Clean and inspect the oil suction pipeline

Regularly clean the oil suction pipeline to ensure that it is unobstructed. At the same time, check the sealing of the suction pipeline and there is no leakage.

Inspect and repair the drive system

Regularly inspect the driving devices of the oil pump, such as motors, belts, etc., to ensure their normal operation. If there is a malfunction, it should be repaired or replaced in a timely manner.

Choose the appropriate oil

According to the usage environment and requirements of the oil pump, select the appropriate viscosity of the oil to ensure the normal operation of the oil pump and stable output pressure.

Correctly install and debug the oil pump

Ensure that the installation position and angle of the oil pump are correct to avoid poor oil suction or obstructed oil discharge. At the same time, by correctly opening and adjusting the inlet and outlet valves of the oil pump, the pressure can rise normally.

Increase maintenance and upkeep

Regularly maintain and upkeep the oil pump, including cleaning, lubrication, inspection, etc., to determine its performance and lifespan.

In summary, the inability to increase the pressure value of the gear oil pump is a complex issue that requires investigation and resolution from multiple perspectives. Only when all parts of the oil pump are running and cooperating properly can the stability of the output pressure and the normal operation of the equipment be determined.
