Product Description

Instructions For Use



1. It is recommended to use L-HM46 or similar viscosity hydraulic oil in summer and L-HM32 or similar viscosity hydraulic oil in winter.

2. Working temperature range -20C-80C

3. The cleanliness of the system directly affects the reliability of the hydraulic components. Before refueling, the oil tank and pipeline should be cleaned sufficiently. The filter with filter accuracy of 100 ηm is commonly used on the suction side of the pump (its rated flow rate should not be less than twice the flow rate of the pump), and the filter accuracy of the return pipeline should not be less than 25 ηm.

4. Driving power Nr = pxqxn / 61200xηv , in which Nr: driving power (kw), p: working pressure (MPa), q: theoretical displacement (ml / r), n: rotational speed (rpm), and ηv: volumetric efficiency is generally 0.9.

5. Before starting, carefully check whether the inlet and outlet oil, rotation direction and the direction indicated by the sign consistent, do not reverse rotation.

6. Flexible coupling should be used between the drive shaft of the pump and the original power output shaft, with different axle degrees not more than 0.1 mm.

7. The radial force, axial force and bending moment of the pump shaft should be ensured. When installing the gear pump, the shaft should be slowly introduced, do not force knocking, axial collision, otherwise it will cause serious damage to the pump.

8. The oil suction height of the pump is not greater than 0.5m.

9. No collision is allowed at the connection flange of the oil inlet. Joint surface and joint must be strictly sealed to prevent leakage, otherwise it will cause noise, vibration, foam and other abnormal phenomena, reduce the life of gear train.

10. The diameter of the oil suction pipe of the gear pump should ensure that the flow velocity of the oil is less than 1.5m/s.

11. If the product is not used in time, fill the interior with rust preventive oil and keep it properly.
