Vane pump 4520V-50A5-1AA-22R, 4520V-60A12-1AA-22R use precautions

As high-performance hydraulic vane pumps, the double vane pumps 4520V-50A5-1AA-22R and 4520V-60A12-1AA-22R need to pay attention to the following matters when using them to ensure their normal operation and extend their service life:

1. Installation and debugging

Pre-installation check:

Before installation, carefully check whether the pump body, rotor, blades and other parts are intact and whether there is any damage or deformation.

Check whether all connections are tight and whether the seals are intact.

Correct installation:

The installation should be carried out according to the installation requirements in the product manual, ensuring that the pump body is placed horizontally to avoid tilting or vibration.

During installation, ensure that the inlet and outlet pipes of the pump are connected correctly to avoid reverse connection or leakage.

Debugging and trial operation:

Before debugging, check whether the motor direction is correct to avoid reverse rotation and damage to the pump body.

During the trial operation, the pressure should be gradually increased to observe whether the pump operation and sound are normal. If there is any abnormality, stop the machine immediately for inspection.

2. Operation and Maintenance

Operating parameters:

During operation, the speed, pressure and temperature of the vane pump should be strictly controlled to avoid exceeding the rated range of the pump.

The operating pressure and flow of the pump should be checked regularly to ensure that they are stable and meet the design requirements.

Hydraulic oil requirements:

The cleanliness of the hydraulic oil has a great impact on the service life of the pump. Clean, impurity-free, and qualified hydraulic oil should be used.

Regularly check the oil level and quality of the hydraulic oil. If the oil level is too low or the oil quality deteriorates, it should be replaced in time.

Bearing inspection and replacement: Bearings are important parts of the pump, and the clearance and wear of the bearings should be checked regularly. If the bearings are found to have abnormal noise, overheating or severe wear, they should be replaced with new ones in time, and ensure that the model and specifications of the new bearings are consistent with the original bearings.

Regular maintenance:

Clean and inspect the pump regularly to remove dirt and impurities inside the pump.

Check the integrity of each seal and replace it if damaged.

Check the pump fasteners regularly to see if they are loose. If they are loose, tighten them in time.

3. Notes

Avoid dry running:

When starting the pump, make sure that the pump is filled with hydraulic oil to avoid dry running and damage to the pump body.

Prevent overload:

During use, the pump should be prevented from overloading for a long time to avoid damaging the pump body or reducing the service life of the pump.

Shutdown and protection:

When shutting down, turn off the power first, then close the inlet and outlet valves to prevent the hydraulic oil in the pump from flowing back or leaking.

If the vane pump is not used for a long time, it should be regularly maintained and serviced to ensure that it is in good condition.

In summary, the double vane pumps 4520V-50A5-1AA-22R and 4520V-60A12-1AA-22R need to pay attention to installation and commissioning, operation and maintenance, and precautions when using them. Only by using and maintaining them correctly as required can the normal operation of the pump be ensured and the service life be extended.
