Installation & Commissioning

1. Q:What hydraulic oil is suitable for the Rexroth PGH2 - 1X/003RE07ME4 gear pump?
   
   
   A:It is recommended to use anti - wear hydraulic oil of ISO VG 46 or above. Avoid using oil products with unqualified viscosity or mixed impurities to prevent damaging the pump body seal and internal components.
2. Q:What should be paid attention to when connecting the inlet and outlet oil pipelines of the pump?
   
   
   A:Ensure the inlet pipeline has low resistance; shorten the pipeline length and increase the pipe diameter if necessary. The connection must be sealed tightly to prevent air leakage, and the outlet pipeline should match the rated pressure of the pump to avoid pipeline burst.
3. Q:How to confirm that the direction of the pump shaft rotation is correct?
   
   
   A:Check the rotation mark on the pump body first. When connecting the motor, conduct a no - load test for 1 - 2 minutes. If there is no oil output or abnormal noise, immediately stop and adjust the motor wiring to prevent reverse rotation from damaging internal gears.
4. Q:Is there a requirement for the installation height of the pump relative to the oil tank?
   
   
   A:It is recommended that the pump be installed as close to the oil tank as possible, and the installation height should not exceed 0.5 meters. Excessively high installation will increase the suction resistance and easily cause cavitation and noise.
5. Q:What preparations are needed before the first start - up of the new pump?
   
   
   A:Fill the pump body with hydraulic oil first, check the oil level of the oil tank to be above the middle scale, clean the filter, and then run it at low speed and low pressure for 10 minutes to check for leakage and abnormal noise.
