Solution To Hydraulic Guillotine Shearing Machine Oil Cylinder Failure

The oil cylinder, also known as the hydraulic cylinder, is the primary component in the hydraulic guillotine shearing machine equipment to complete energy conversion and transport oil. If the oil cylinder works abnormally, it can cause instability in the shearing machine system. To ensure the normal operation of the shearing machine, the cause of the fault should be identified as soon as possible and repaired in a timely manner.

  1. Insufficient oil supply from the hydraulic pump of the shearing machine: This is due to the wear of internal parts in the hydraulic pump, which reduces the volumetric efficiency of the pump and increases the load on the oil cylinder, resulting in an increase in pressure and an increase in internal leakage. The increase in leakage will cause the pump to deliver to the oil cylinder at a speed that does not meet the specified value.
  2. The connection between the hydraulic cylinder of the shearing machine and the load is not accurate: when the connection step of the load is incorrect, it can cause the speed of the cylinder to slow down when moving, resulting in abnormal operation of the hydraulic cylinder.
  3. There is an issue with the layout of the hydraulic cylinder: the piston end face is tightly attached to the cylinder end face, and the piston bearing area is insufficient during startup, which prevents it from pushing the load, resulting in a slowdown in the speed of the shearing machine oil cylinder movement.
  4. Problems with the relief valve: If the relief valve spool stuck in the open position, a large amount of oil from the relief valve overflow back to the tank, will make the flow into the cylinder increased and lead to slow down.
  5. The small volume of the accumulator or the low inflation pressure are also the primary reasons for the abnormal operation of the shearing machine oil cylinder.
