Common failures of single-arm hydraulic presses in operation

The single-arm hydraulic press has a relatively good performance in terms of straightening and press-fitting, and has always been loved by users. However, mechanical equipment is more prone to failure. Today, I will briefly introduce the few small ones often encountered in the operation of hydraulic presses. Failure for user's reference.

1. Failure of oil leakage.

This kind of failure is relatively common, and it is also very intuitive to see. If oil leakage is found at the position of the hydraulic oil pipe and seal, replace the corresponding parts in time.

2. Large vibration and abnormal noise.

This type of failure is usually caused by air entering the oil, which can be checked from the oil pressure pipeline. Pay attention to check whether the oil position in the oil tank is normal and whether the sealing device is too worn.

3. Oil problems.

This kind of failure is also the most common. It is necessary to ensure the cleanliness of the oil, and the oil temperature should not be too high, to avoid the oil temperature being too high, and the thin pressure of the oil side cannot reach the preset value.

4. The pressure cannot reach the specified preset value.

Such failures need to check whether the oil pump piston of the single-arm hydraulic machine is lubricated and whether the piston needs to be replaced.
