What are the common troubleshooting methods for the new hydraulic oil press? What to do when not sucking oil?
- 1. When the oil pump is not sucking oil for maintenance, if the filter is blocked by dirt, the filter should be disassembled and cleaned. If the oil has been used for a long time, because the sediment adheres to the fuel inlet movable door, the movable door is not tight, you should replace the new oil or release the old oil for filtering, and clean the fuel inlet movable door. If the amount of oil in the oil tank is insufficient, add enough oil to the oil tank. If there is no vacuum in the oil pump, you can pull out the small piston, inject oil and then press it.
- 2. When the oil pump is under pressure for maintenance, if the valve is dirty or has poor sealing, it can be disassembled, washed and ground to make it tight. If it is a poor contact between the oil inlet valve plug of the oil press and the valve seat, it can also be disassembled, washed and ground to make it tight. If the oil inlet valve plug of the oil press is in poor contact with the valve seat or is not tightened to cause oil leakage, you can grind the oil inlet valve plug and valve seat on the oil press to make them close together and tighten the screw plug. If it is a small piston, the gap with the pump body is too large after wear, and the pump should be replaced.
- 3. When the oil cylinder and piston are leaked and repaired, if the cup is installed wrongly, it should be installed correctly and reinstalled according to the correct side. If the leather bowl is damaged, it should be replaced with a new one.
- 4. When checking the valve port failure, if there is dirt in the oil and the steel ball valve is not sealed, clean the anquan valve to remove the dirt and close the steel ball valve. When the spring loses its elasticity and cannot withstand high pressure, a new spring should be replaced.
When the adjusting screw is loose, the jump valve is not reached when the specified pressure is not reached, and the screw should be re-adjusted to make the jump valve when the pressure reaches the specified pressure. If you work with overpressure frequently, the steel ball will damage the valve. The valve should be reground and replaced with a new ball. Pay attention to the operating procedures.
