Initial startup check
Check the design and installation accuracy of the hydraulic station:
● Extend the distance between the entrance and exit as much as possible.
● The inlet and outlet nozzles should be inclined, and the cross section of the beak should be greater than or equal to 45 ° in order to increase the cross section of the channel and reduce the speed. The recommended water inlet speed is between 0.5m / s ~ 1.9m / s. . And the exit is below 6m / s.
● In the worst case (for example: all hydraulic cylinder pistons are extended to the extreme position), confirm that the oil port is lower than the oil level in the fuel tank,
● The size of the air filter should be three times larger than the maximum return flow.
● An exhaust release valve is set on the oil return pipe; and the connector at the pump outlet can be slightly loosened to exhaust until there are no air bubbles in the oil leakage, and then the connector can be tightened to produce the same effect.
Note: This method is suitable for low pressures and should ensure that the pressure does not rise.
Initial start:
● Check the accuracy of the position of the fuel supply port.
● When filling oil, the pump should be well ventilated.
● Run the pump slowly for a few seconds, then release the relief valve at the outlet to reach the minimum pressure.
● Do not drive the pump at high speed and high pressure until the inspection is completed.
Shafts and couplings
Spline hole
● The spline hole of the coupling should be floating and automatically centered to reduce wear. The deviation of the slope of the two spline shafts should be less than or equal to ± 0.05 / 25.4mm (dialometer deviation)
● Spline holes must be lubricated with lithium molybdenum disulfide-based grease or other similar greases.
● The coupling needs heat treatment to reach a hardness of 29 ~ 45HRC.
● The specifications of the spline hole are flat teeth and side teeth, which should meet the first level standard of SAE-J498b (1971).
Spline shaft
● T7, T67 and T6 series vane pumps have high-strength keys, so it must be used when installing or replacing the pump. New keys with a hardness of 27 ~ 34HRC and corners of 0.8 ~ 1 * 45 ° can also be used. Avoid rounded corners in the key slot when the key needs to be replaced.
Shaft load
● The required structure of a flat spline shaft is the same as that of a spline shaft.
This series of products are only allowed to withstand the transmission load, and do not apply radial and axial loads.
T Series Vane Pumps is a high performance, low cost pump. Balanced design and lip blade technology are key features. It is also a favorite product in industry. Zhejiang Yongling Hydraulic Machinery Co., Ltd. is a professional Chinese manufacturer and supplier of T series vane pumps.
