Practical operation and maintenance suggestions 1. Pressure monitoring: Regularly check the pressure value of the hydraulic system to ensure that it is within the range specified by the manufacturer. For example, the hydraulic pressure of the Hi-Sea top drive needs to be maintained at 16 MPa. The pneumatic system pressure needs to be maintained at 0.6 MPa to 0.8 MPa to avoid damage to components due to excessive pressure or too low pressure to affect the function. 2. Abnormal handling: If the...
