Reason
|
solution
|
1.The press block moves up and down unsteadily, with obvious vibration or gaps, and the pressure rises slowly.
|
1.Air in hydraulic system
|
1.Open the bleed valve at the top of the oil cylinder to remove the gas
|
1.When shutting down and maintaining pressure, the oil pressure will drop rapidly.
|
1. The sealing ports of the one-way valve and the oil separator of the oil pump are damaged or the hydraulic oil is dirty.
|
1.Depending on the situation, grind the valve port, clean the oil, or replace damaged components of the sealing device, etc.
|
|
2. The pump, oil separator and sealing device components in the cylinder are damaged.
|
2.Replacement accessories
|
1.The up and down movement of the pressing block is unstable
|
1. After the gear end face is worn, the gap increases and oil leakage is more
|
1. Repair the gear pump and reduce the end clearance.
|
|
2. The oil is not clean and the oil filter is clogged.
|
2. Clean the oil filter and clean the working oil.
|
1.Hydraulic return stroke is too slow
|
1.The oil is not clean
|
1. Replace with new working fluid.
|
|
|
2. Clean the oil filter and clean the working oil.
|
1.The hydraulic thrust pressure is not enough.
|
